No you cannot. We only support each audio and video codec in the explicit containers defined in questions 1 through 4.

6. How can I determine if a video file that I am trying to play conforms to the specifications as laid out in questions 1 through 4?

You can use a 3^rd party tool to analyze your video files to determine what audio and video codec is used. A popular 3^rd party tool to analyze video files can be found at http://www.headbands.com/gspot/.

7. How do I create WMV, AVI, H.264 and MPEG-4 content? What encoders does Xbox 360 support?

You can create this content on one of many 3^rd-party applications. Xbox 360 supports many popular encoders. Specifically for encoding to WMV you can use Microsoft Expression Encoder or Windows Media Encoder.

From Windows Home Server to Xbox 360 Dashboard Video Player	WMV(Protected), WMV(Unprotected), AVI
From Windows Media Center to Xbox Media Center Extender	WMV(Protected), WMV(Unprotected), Mpeg2

* = Please refer to question 32 on how to configure Windows Media Player to share these file types to the Xbox 360.

11. What is the "real" max bit rate, resolution, and frames per second that you support for all the different formats?

Xbox 360 does not specifically block video from playing based on a maximum bit rate, resolution, or frames per second. The maximums listed above for each codec are what we have tested for various video playback sources. Higher rated content will not be blocked, but playback may be less then optimal. Use higher bitrates at your own risk.

12. What size USB storage device does the Xbox 360 support?

The Xbox 360 will support as big of a storage device as you can format using FAT32. Unfortunately when formatting a device in Windows Vista or Windows XP you will be restricted to a maximum FAT32 size of 32GB. You can work around this limitation by using a 3^rd party utility or using an alternative Operating System that does not have this restriction. Please note that the maximum size of any single file on FAT32 is 4GB.

13. What is the maximum video file size that is supported?

The maximum file size for an AVI, MPEG-4 Part 2, and H.264 file that can be played is 4 GB. 4GB is also the maximum size of any single file that you can store on a FAT32 USB hard drive. However, Windows Media Player 11 and the Zune software do support streaming WMV files greater than 4GB.

14. Do you support 5.1 channel AAC?

No. Only 2-channel AAC is supported. If you want to play a 5.1-channel video on your console, you will need to encode it to WMV with WMAPro 5.1 audio or use the AVI container with Dolby® Digital 5.1 audio.

**15. What types of AVI files are supported?

The Xbox 360 supports files encoded using MPEG-4 Part 2, Simple and Advanced Simple Profile. These files are often referred to as Xvid or DivX® video files. Many common PC DVD authoring tools, cameras, and camcorders are capable of encoding files using MPEG-4. Note that some files authored for DivX devices may also contain additional functionality(menus, subtitles, multiple audio tracks, etc). The Xbox 360 will attempt to play these files, but does not support any of the additional functionality and in some cases will be unable to play the file.

16. Why don’t some of my older versions of DivX® files play?

Since we only support Mpeg-4 compatible codec implementations, we will not be able to play video files older than DivX® 5.0.

17. Does the Xbox 360 support video artwork when browsing my collection from Windows Media Player 11 or the Zune PC software?

The Xbox 360 will display whatever video artwork that is displayed in Windows Media Player 11 or the Zune PC software for each video file.

**18. Does the Xbox 360 support video artwork when browsing my collection from a USB 2.0 FAT32 removable drive or optical media?

For all video types we will search for a corresponding .jpg file and use that as the artwork. For example video1.avi would display the artwork in video1.jpg if it existed. In the absence of this file, for the mp4 container, we will search if the video file has embedded album artwork and display that instead. Please note you cannot use this method when streaming from Windows Media Player 11 or the Zune PC software. See question number 21 for more information.

19. What is the maximum album artwork size that the Xbox 360 supports?

You should not exceed 512KB for all scenarios. This includes embedding artwork in the mp4 container, storing artwork alongside the file in a separate .jpg container, or streaming from Windows Media Player 11 or Zune PC software.

**20. How does the “Sort by Type” and “Sort by Title” option work when browsing my own generated video content?

The “Sort by Type” option is the typical Windows Explorer view that a computer would show your files in. It will first alphabetically sort your folders and then alphabetically sort your files. The “Sort by Title” option allows you to sort all folders and files alongside each other. Both of these sort options are persistent and linked to your profile so that you do not need to set them every time. See question number 21 for more information.

**21. What is a sample way of organizing my video hierarchy so that I can best utilize artwork and folder structure on the Xbox 360 for my personal video collection?

The following example uses the sort option “Sort by Title” on a USB hard drive connected to the Xbox 360:

· Genre 1 (Folder)

· Genre 2 (Folder)

· Video 1.avi (File)

· Video 1.jpg (File) (Artwork)

· Video 2.mp4 (File) (Artwork embedded in file)

· Video 3 (Folder)

· Video 3-1.wmv (File)

· Video 3-2.mp4 (File)

· Video 3-2.jpg (File) (Artwork)

· Video 3-3.wmv (File)

· Video 3-3.jpg (File) (Artwork)

· Genre 3 (Folder)

22. How do display modes work?

There are 5 display modes: auto, letterbox, fullscreen, stretch, and native. You can access these modes while watching a video by pressing Display on your remote or A on your controller.

a. The auto setting attempts to automatically determine what the best viewing experience is for your video. If it is a very low resolution video, it will enlarge it enough to be viewable on your screen while limiting the size for optimal viewing. If the video is of higher resolution, it will it will enlarge it to fit the TV. For both scenarios, it will retain the aspect ratio of the original video (for example, 4x3 or 16x9).

b. Letterbox mode will display your image full screen while retaining the aspect ratio of the original video. Use this if you want to override the auto function and fit the content to your TV.

c. Fullscreen mode will display your image full screen with the assumption the video is 16x9 formatted for 4x3 screens. This can be helpful for older content that may be 4x3 with black bars encoded into the video. This mode will allow you to zoom through the black bars and see it as wide screen.

d. Stretch mode will display your image full screen and stretch 4x3 content horizontally to fill a 16x9 TV. This can be helpful for those who always want to fill their TV regardless of the aspect ratio of the content. This causes 4x3 content to appear stretched.

e. Native mode allows you to see the content at its original resolution. Use this to view content that is extremely low resolution or very low bitrates.

23. How are display mode settings saved?

Every time you watch a new video, the display mode defaults to auto. If you decide to change the setting, each time you watch the same video the console will remember what you chose last time.

24. What is the information bar?

The information bar on the on-screen display now shows you exactly where you are in the video and where the chapters are in the file. In addition, for downloaded content, it will also show how much of the video has been downloaded.

25. How are the chapters determined?

Each video is divided into 10 chapters, allowing you to quickly move around the video content. Use skip to move to the next or previous chapter. Each chapter appears as a tick on the information bar.

**26. Can I fast forward, rewind, and skip while watching content while it's being downloaded from Xbox Live Marketplace?

You can move around in video as much as you have already downloaded. If you skip or watch past the point that you have already downloaded, you will be required to wait for it to buffer enough to begin normal playback again.

27. Is there other 3^rd party software out that I can use to stream from my PC to my Xbox 360?

The Xbox 360 team extensively tests that we work well with Windows Media Player 11 and the Zune PC software. If you do decide to use 3^rd party software, please contact them directly for support.

28. How can I stream content from my Mac?

To share from a Mac computer you will be required to use a 3^rd party streaming solution. Please note that we do not support 3^rd party streaming solutions and you will be required to contact them directly for support.

29. After the May 2007 update, my 3^rd party software doesn't stream videos correctly. Why?

Video navigation was changed in the May 2007 update. 3^rd party software that does not support folders through network sharing will not work correctly. You'll have to contact the software developer for support.

30. How can I set up Windows Media Player 11 or Zune to share my media to my console?

For info about setting up sharing, see www.xbox.com/pcsetup.

31. Should I continue to use Windows Media Connect (WMC) to stream video to my Xbox 360?

Windows Media Connect can be used but is no longer supported outside of Windows Home Server. We strongly suggest people upgrade to Windows Media Player 11 or use the Zune software to receive the best experience for managing and streaming content to Xbox 360.

32. How can I get Windows Media Player 11 to stream MPEG-4 Part 2 and H.264 to my console?

By default, Windows Media Player 11 does not support MPEG-4 Part 2 and H.264. Your first option is to install a 3rd party MP4 DirectShow decoder to import MPEG-4 part 2 and H.264 files into your library. Once they are in your library they can be streamed to your console and they can be played from within Windows Media Player 11 on your PC.

An alternative approach is to rename all of your mp4 files to have an “.avi” file name extension. This will enable Windows Media Player 11 to import them into the library and will allow them to be played on your Xbox 360. To enable the playback of these files on the PC, you will still need to install an appropriate decoder on the PC.

33. I can't see my video files from the Zune software on my console. What's wrong?

Make sure that the folders containing the videos you want to share with your console are included in the Zune software's list of monitored folders.

34. I received a message that says a media update is required to play the content. When I download the update I get the message "The download could not be completed. Please try again later. Any points you used for this transaction have already been deducted from your balance and will not be deducted again" with error code 80070005. Explain.

You'll get this error if you previously downloaded the media update on another Xbox 360 console with the same profile. You are only allowed to download the update on one console per profile. You can work around this by creating a temporary Silver membership to download the update. Once it's downloaded, you will be able to use the update with any profile.

**35. What shortcuts can I use with my gamepad while using the Video area?

LB skips backward one chapter. RB skips forward one chapter. RT fast forwards. LT rewinds. Start toggles between play and pause. X and Y bring up the On Screen Display for more advanced options. While browsing through your lists of videos you can also push Start to automatically begin video playback using the bookmark if it exists bypassing the Resume/Restart page. You can also use RT or LT to page up or page down through lists of items.

**36. Why do I see the message “Updating content. This may take a few minutes. Please wait.” the first time when entering the Console video area?

To support grouping television and game videos your content metadata needs to be updated. Once this process is completed subsequent entries into the Video area will be very quick. Please be patient during the update process and allow it to complete updating all of your content metadata.

**37.What changes have you made to selecting the source for Videos, Music, and Pictures?

The source selection is now mapped to the X button for each of these areas. The Xbox 360 will remember the last source that you picked and default to that. We have also removed the computer affiliation from the System Blade and we now show a list of all the computers that you can connect to directly in the Select Source scene. This allows you to quickly jump between Windows Media Player 11 and Zune PC software media shares.

**38.How can I play music from my iPhone® and iPod Touch®?

Unfortunately the iPhone® and iPod Touch® uses a different mechanism for storing your music then a traditional iPod®. We are currently unable to play music from the iPhone® or IPod Touch®. You can still browse the pictures stored on these device through the Pictures area in the Xbox 360 dashboard.

**39.Can I play videos from my iPod®?

The Xbox 360 does not support playing videos from an iPod®.

40. When trying to play 25 or 50 fps content, I don’t get any video over VGA

This only affects consoles which output PAL-50 and PAL-60 output modes. There is a known issue in which 25 or 50 fps video sometimes doesn’t display over a VGA connection if you have previously connected your Xbox over component video output.

The workaround for this issue is as follows:

1. Connect your Xbox 360 to a display device using a component video cable

2. Go to the System Blade

3. Go to Console Settings

4. Go to Display

5. Set your display settings to a different resolution than is currently selected (e.g., set it to 480p if your current setting is 720p)

6. You should see a slider with the words “Your display settings have changed. You can keep this setting or try another. Do you want to keep the new settings? If you keep the new settings, your TV will be tested to see if it also supports this setting at 50Hz.” Answer “Yes, keep these settings” to this prompt.

7. After this your display will be tested for 50Hz output

8. You should see a slider with the words “Now displaying at 50Hz. Does this display appear correctly?” Answer “No” to this prompt even if the display is correct. Again, make sure to answer “No” to this prompt.

9. Connect your Xbox up via VGA again. The videos should now play correctly.

41. I can’t stream content to the Xbox after upgrading the Zune software to version 2.1

After you upgrade the Zune software to version 2.1 on a Windows XP-based computer, you may be unable to use the Media Sharing feature to connect to an Xbox 360 system. This issue may occur if you used an account that has administrative permissions to log on to the computer when you upgraded the Zune software.

December 2007 System Update

2007-11-30T05:00:00Z

Hello Everyone!

Coming shortly is our December 2007 System Update, one where we've added a lot of new features that you guys have been asking for. You should be prompted for the update early next week on December 4^th.

This is the seventh system update I've been responsible for and I recently went back and reviewed the previous major updates we published in June '06, November ‘06, and May ‘07. It is amazing how far the console has come since 2005! And knowing all the work that has gone into this current update I stand back and feel super-proud of the Xbox Console Team. The incredible innovation and efforts they continue to put into the platform each day is unbelievable.

Maintaining a twice yearly ship schedule is difficult. Launching major services like Video Marketplace is challenging. Designing and launching an external HD-DVD player from scratch in 10 months is difficult. Growing our library of backwards compatible titles to almost 500 supported games is demanding. But hearing feedback from our users and seeing our platform succeed makes it all worthwhile. And it makes us want to tackle even more.

Did you know our system update package is only 7MB in size? Or that the entire 360 O/S resides on a tiny 16MB filesystem and when running it is only given 32MB of system memory? I mention this as our developers and testers do an amazing job of coding for performance, and that is overlooked by a lot of people. Each day they are faced with adding more features, improving performance, and creating magical experiences with those hard-capped limits. And release over release they are able to pull off some magic to make it happen.

I feel really lucky to work with such an amazing team. We love the 360, and we are passionate about making it better! Remember the team is listening to your comments on Xbox.com and on Major Nelson's site so please continue to provide the feedback!

The team is already thinking about the next update and after some well deserved time off for the holidays we'll again be working to improve your 360 gaming experience.

4. How do I create H.264 and MPEG-4 Part 2 content? What encoders does Xbox 360 support?

You can create this content on one of many 3^rd-party applications. Xbox 360 supports many popular encoders.

5. What are the different ways to play video content on Xbox 360?

You can play video from a USB 2.0 FAT32 removable drive, optical media, and by streaming from the Zune software or Windows Media Player 11.

6. What is the "real" max bit rate, resolution, and frames per second that you support for all the different formats?

7. What is the maximum video file size that is supported?

The maximum file size for an MPEG-4 Part 2 and H.264 file that can be played is 4 GB. However, Windows Media Player 11 and the Zune software do support streaming WMV files greater than 4GB.

8. Do you support 5.1 channel AAC?

No. Only 2-channel AAC is supported. If you want to play a 5.1-channel video on your console, you will need to encode it to WMV with WMAPro 5.1 audio.

9. Do you support DivX?

No.

10. Do you support MPEG-2?

No. Xbox 360 Media Center Extender does support MPEG-2, but you can't play this content in the Xbox 360 video player .

11. Does Xbox 360 Media Center Extender support MPEG-4 Part 2 and H.264?

Not at this time. You must play these videos in the Xbox Dashboard.

12. Does Xbox 360 display embedded artwork for MPEG-4 Part 2 and H.264 files?

Yes. You can embed your artwork that is less than 400KB in the video files and they will be shown in the Xbox 360 video area when streaming from the Zune software.

13. How do display modes work?

There are 5 display modes: auto, letterbox, fullscreen, stretch, and native. You can access these modes while watching a video by pressing Display on your remote or A on your controller.

a. The auto setting attempts to automatically determine what the best viewing experience is for your video. If it is a very low quality video, it will enlarge it enough to be viewable on your screen while limiting the size for optimal viewing. If the video is of higher quality, it will it will enlarge it to fit the TV. For both scenarios, it will retain the aspect ratio of the original video (for example, 4x3 or 16x9).

b. Letterbox mode will display your image full screen while retaining the aspect ratio of the original video. Use this if you want to override the auto function and fit the content to your TV.

e. Native mode allows you to see the content at its original resolution. Use this to view content that is extremely low resolution or very low bitrates.

14. How are display mode settings saved?

Every time you watch a new video, the display mode defaults to auto. If you decide to change the setting, each time you watch the same video the console will remember what you chose last time.

15. What is the information bar?

The information bar on the on-screen display (OSD) now shows you exactly where you are in the video and where the chapters are in the file. In addition, for downloaded content, it will also show how much of the video has been downloaded.

16. How are the chapters determined?

Each video is divided into 10 chapters, allowing you to quickly move around the video content. Use skip to move to the next or previous chapter. Each chapter appears as a tick on the information bar.

17. Can I fast forward, rewind, and skip while watching content while it's being downloaded from Xbox Live Marketplace?

You can move around in video you have already watched. For example, if you watch 15 minutes of a TV show, you can to go back 10 minutes and then skip forward to the 15 minute mark again (where you left off). After the video is fully downloaded, you can move through the entire video.

18. After the May 2007 update, my 3^rd party software doesn't stream videos correctly. Why?

19. How can I set up Windows Media Player 11 or Zune to share my media to my console?

For info about setting up sharing, see http://www.xbox.com/en-US/support/systemuse/xbox360/digitalmedia/pc.htm.

20. Should I continue to use Windows Media Connect (WMC) to stream video to my Xbox 360?

Windows Media Connect can be used but is no longer supported. You can manage and stream content to Xbox 360 with Windows Media Player 11 or the Zune software.

21. What are the different video codecs that Zune and Windows Media Player support out of the box for streaming?

The Zune software supports unprotected WMV, MPEG-4 Part 2 and H.264. Windows Media Player 11 supports protected and unprotected WMV.

22. How can I get Windows Media Player 11 to stream MPEG-4 Part 2 and H.264 to my console?

By default, Windows Media Player 11 does not support MPEG-4 Part 2 and H.264. You can either convert your MPEG-4 Part 2 and H.264 content to WMV or you can install a 3rd party MP4 DirectShow decoder pack to import MPEG-4 part 2 and H.264 files into your library. Once they are in your library they can be streamed to your console just like WMVs.

23. I can't see my video files from the Zune software on my console. What's wrong?

Make sure that the folders containing the videos you want to share with your console are included in the Zune software's list of monitored folders.

24. I received a message that says a media update is required to play the content. When I download the update I get the message "The download could not be completed. Please try again later. Any points you used for this transaction have already been deducted from your balance and will not be deducted again" with error code 8070005. Explain.

FAQ Updates: 5/16/07:

Q: Why does some WMV content that played correctly before the updated version now play in the wrong aspect ratio or with severe stuttering issues?

A: Some content created by third-party encoders does not correctly set file attributes used to play video files and this can result in videos playing in odd aspect ratios. In addition, some higher resolution WMV v7 and v8 files may stutter and audio may not stay in sync with video. These issues will be addressed in the next release. To work around this issue you can re-encode your files to WMV9 with Windows Media Encoder available from www.microsoft.com.

Hmm, looks like we got there first. Again.

Emergence Day

2006-11-04T03:15:00Z

What takes 4.7 million lines of code, partner teams from all over Microsoft, and millions of dollars to create? The Xbox 360 system software? Nope. This is just the HD DVD player.

The Xbox platform team (us) is experiencing its own emergence day as of late; we've been hard at work for the past 8 months straight bringing the fall system update to fruition. I haven't even posted since August. Daryl's already gone over a lot of the features and changes that are in this release. I've personally been working on the Xbox 360 HD DVD player (which, by the way, reached the #1 best seller slot on Amazon.com's video games category) and I thought I'd go over some of the technical difficulties it takes to bring HD DVD to market.

There's a perception that HD DVD is just DVD with HD content, but once you look at things more closely, it's clear that HD DVD is a different beast altogether. The Xbox platform team became serious about HD DVD last year, when Microsoft as a company threw its endorsement behind the standard.

The Xbox 360 HD DVD Player, for the most part, is an entirely software based implementation. Other players on the market have specialized chips (called DSPs) that decode things like H.264, MPEG, VC1, DTS, Dolby Digital, and other codecs. Much like how backwards compatibility for Xbox 1 works on Xbox 360, the heavy parts of HD DVD are all done on Xbox 360's triple-core CPU.

If DVD is an audio/video pipeline with some navigation data (go to the menu, start playing, etc.), HD DVD can be considered a runtime environment where audio/video playback is just one major feature. So let's break down that 4.7 million lines of code. I don't have the numbers for each component, but each of these is a very significant chunk:

Video Codecs: H.264, MPEG-2, VC1
Audio Codecs: Dolby Digital+, DTS, TrueHD, LPCM, MPEG
HDi: The HD DVD runtime engine.
GDI: Drawing stuff like menus
AACS: Cryptography/DRM stuff
MF: Audio/Video pipeline

That's a lot of stuff. Some of the acronyms may not be recognizable. GDI is the Graphics Device Interface, which has been a mainstay of the Windows operating system for many years, providing facilities to draw stuff on screens. MF is Media Foundation - a framework for audio/video pipelines that was being built for Windows Vista. The Windows teams in charge of the above components all pitched in to make them work on Xbox 360 while continuing to work on other Windows projects (Vista, CE, etc.) - quite a task.

A lot of the codecs existed in code at Microsoft before the Xbox 360 HD DVD Player was being built. However, it was all code that was optimized for PC platforms (windows/x86) and not Xbox 360's PPC core. This meant doing a lot of optimization. In this regard, the Xbox 360 implementation of H.264 can be considered a crowning achievement. For this computationally expensive codec, a hybrid approach was taken. Since GPUs are very good at parallelized workloads, stuff that could be parallelized is computed there, while the stuff that can't is better suited to the CPU and is done there.

Unlike DVD, where typical players pass the audio data from the disc through to your receiver, HD DVD requires that players mix sounds from menus and such in with the audio being played for the movie. The 360 player software decodes all the above codecs in software, mixes anything that needs to go together, re-encodes it into Dolby Digital and then sends that to your receiver. So, don't be alarmed when your receiver still says "Dolby Digital" even if you've selected DTS in the menus.

All 6 of Xbox 360's hardware threads are hard at work while playing back an HD DVD. At the moment, the player software pushes Xbox 360 harder than any other (save, perhaps, Gears of War during some particularly busy parts of the game).

If I'd have known how much work it was going to be bringing the 360 HD DVD Player out this year, I may not have signed up last year, but now that I can watch HD movies, it's hard to go back to crummy old DVD :)

Streaming High Def over a Wireless Network

2006-11-01T22:02:00Z

Streaming High Definition Video over a Wireless Network

With the Xbox 360 Flash Fall 2006 System Update, we've added support for WMV video playback from new sources. If you've read the video format post, you'll see that your Xbox has the ability to playback high definition (HD) video encoded in the Windows Media Video 9 Advanced Profile (VC1) codec. This means that you'll not only be able to watch High Definition video from external sources like a USB drive, CD, DVD, but also PC.

However, when you decide to stream HD content over your home wireless network, you might see performance degradation in the form of choppiness. This post is to provide you with some workarounds and suggestions to fix the choppiness.

Workarounds

Generally the performance degradation happens due to issues like interference, assuming you have an 802.11g router. The easiest, most cost-effective way to get around this is to wire your Xbox to your router via a LAN cable. Doing so will provide the best streaming quality bar none; although that probably was not the answer you wanted to hear.

A second (albeit more expensive) workaround is to purchase a router capable of 802.11a. Choppy video performance is likely due to either too much interference on your wireless’ operating frequency due to home appliances (i.e. the microwave, the cordless phone, or Bluetooth devices) or too much interference on overlapping g wireless channels.

802.11a has clear (non-overlapping channels) and operates on 5Ghz, a frequency that doesn’t have as many home appliances running within it, which makes it a better mode to stream anything that requires a lot of bandwidth. For more information on the differences between 802.11a and g, jump down to “802.11a vs. 802.11g.”

Through testing done by the Windows Media Center Team, it was determined that 802.11a is almost on par with 802.11g in terms of barrier penetration and range. Even so, it’s advised that you should only pass 802.11a through at most one wall for the best performance. If you still run into problems, even with 802.11a, you can read more about 802.11a drawbacks and an optimal environment by jumping down to “An optimal wireless streaming environment”

I wasn’t trying to stream HD content; I was trying to stream standard definition content over my 802.11b network!

You’ll probably notice that there wasn’t really mention of 802.11b in the workaround discussion. While it’s still a valid wireless mode, it’s the weakest of the three modes, capable of only providing ~6Mbps in ideal instances on an operational frequency of 2.4 Ghz. This mode will likely have problems even streaming non HD content, and is unable to stream HD content. If possible, for all content, use at least 802.11g which will give you good performance with standard definition content; 802.11a will likely give the best results for both standard and high definition content.

How do I know what wireless mode my 360 is connected to?

Start up your 360 without a game and it will boot to the dashboard. Go to the System Blade and scroll down to Network settings. Press A to see your Basic settings and you should see what 802.11 Wireless Mode your 360 is connected on be it a, b, or g.

802.11a vs. 802.11g

Yes, 802.11a and 802.11g have the same max throughput (25 Mbps not 54 Mbps as advertised due to WiFi being half-duplex communication technology). Streaming High Def usually requires about 19-24 Mbps, which means that your WiFi mode, be in a or b/g needs to be running at max throughput through the course of your video. Interference on a g network can compromise the performance of your WiFi network and thus cause degradation in performance.

The operational frequency of 802.11g is 2.4 Ghz, which is a common operating frequency for devices such as the microwave, all Bluetooth devices, and cordless phones. This means that if you have any of the above devices running, your home network could take a hit in performance due to the interference generated by your household appliances. The operational frequency of 802.11a is 5 Ghz which is a more uncommon operating frequency, mitigating it from interference caused by other devices.

IEEE 802.11 a/b/g all communicate in their respective operational frequencies by splitting their frequencies into several channels. A major difference between b/g and a is that the channels in b/g overlap, creating interference whereas the channels in a do not. In general, channel 1 on a b/g network overlaps with channels 2, 3, 4, and 5. This means that if your home network is on channel 1, but your neighbor’s home network is on channel 2, your WiFi signals may interfere, causing a degradation of performance for both networks (WiFi pollution). Contrast to this is 802.11a which has 12 clear channels meaning there’s less of a chance that you will incur a performance hit.

An Optimal Wireless Streaming Environment

We’ve found that optimal streaming performance occurs when you have either your PC or your XBOX connected to your router via a LAN and the other connected wirelessly over 802.11a. If you connect your PC to the router, then connect your Xbox wirelessly via Wireless Networking Adaptor to the 802.11a router or vice versa, do not connect both the PC and the Xbox to the router wirelessly.

Your 802.11a router should be in less than 20-feet with a clear line of sight to the device that’s connected to it wirelessly. This is especially important for 802.11a which theoretically has less range and worse material penetration than 802.11b or 802.11g.

The end goal is to reduce the amount of devices on the WiFi network to reduce any possible factors that might degrade performance.

Fall '06 Supported Video Formats

2006-11-01T02:16:00Z

As you may have heard, with the Xbox 360 Flash Fall 2006 System Update we are adding support for WMV video playback from new sources. Videos can be streamed from a PC running Windows Media Connect, Windows Media Player 11, or the new Zune client player, and can also be played from Optical Disc and most USB mass storage devices. For all these sources, only the WMV video file format and codecs are supported.

How do I know if a video file will work on the Xbox 360?

Currently only the Windows Media Video (WMV) file format and codecs are supported. If you have a file with a “.wmv” extension, then the odds are pretty good that it will work. Technical details on the types of files we support can be found at the end of this post, but the easiest way to find out if a file will work or not is to just try it. Hopefully after you click play the video will show up on your display, but if the content is not supported you will simply get an “Unplayable Content” message blade from the side of the screen and then be returned to the Video blade.

How do I create videos that will play on my Xbox 360?

Windows Movie Maker, a standard feature of Windows XPSP2, will output WMV video files compatible with the Xbox 360 console. Either use the default settings when you finish a movie and click “Save to my computer,” or just make sure that the output video format you select shows the file type as “Windows Media Video (WMV).”

Videos will usually look best when they are closest to the original resolution that they were created with. Try to create video files at least 360 pixels high in vertical resolution in order to minimize content upscaling on the console.

If you decide you want finer control of the output video file format, download a version of Windows Media Encoder (http://www.microsoft.com/windows/windowsmedia/) and then start encoding away. Optimal size and bitrate settings will vary depending on the source material you are encoding. As a general guideline though, 1.5 Mbps is a typical bitrate that should be suitable for most standard definition content, and 8 Mbps is a common bitrate for high definition content.

Can I get more technical details about the kinds of files you support?

WMV video files with the extension “.wmv” are stored in a generic file container format known as ASF. ASF files can contain many different types of codecs within them. Xbox 360 supports most common WMV video codecs, as seen in the following chart:

Supported Video Codecs:

Name	FourCC
Windows Media Video 7	WMV1
Windows Media Video 8	WMV2
Windows Media Video 9	WMV3
Windows Media Video 9 Advanced Profile	WVC1

There are some files with “.wmv” extension that may play on a PC, but are unsupported on the Xbox 360 console. Windows Media Screen, Windows Media 9 Image (Photostory), and some older Microsoft codecs are unsupported, as seen in the following chart:

Unsupported Codecs:

Name	FourCC
Microsoft MPEG-4 Video Codec V3	MP43
Microsoft MPEG-4 Video Codec V2	MP42
Microsoft MPEG-4 Video Codec V1	MP41
Windows Media Screen V9	MSS2
Windows Media Screen V7	MSS1

The Xbox 360 November '06 Fall Update is heading your way

2006-10-31T01:20:00Z

Hello everyone,

Wow, only 5 months have passed since we first posted about the Spring update. The release process never seems to slow down but as tired as we all are, I’m still excited to be talking about our third major update to our system software for Xbox 360. Later tonight (or early in the morning depending on your location) the November ’06 update will go live and with it you will get to see the work we’ve put in over the last 5 months.

Coming out of Spring we looked really hard at all the feedback each of you provided. We are always listening to our Product Support people. We dissected the replies from Major Nelson’s blog and of course we review the feedback from the Xbox.com forums. In addition we are all gamers, and we are passionate about making our product better. This will be the third evolution of our system software and with it I’m super proud of what we’re delivering. I’m hoping that you guys will be too.

Back in my original post from June I explained the concept of ‘Your Games, Your Friends and Your Lifestyle’. This is still something we pivot around in our planning for Xbox 360 and it provides a good framework to talk about some of the changes we’ve made with this release.

For Your Games, we invested heavily in enabling new experiences. The Xbox 360 Wireless Racing Wheel is an awesome accessory and we worked around the clock to make sure that there was support in the system for this cool new experience. Wireless is where it’s at in the Next-Gen and this is why we’re excited to also provide support for the Xbox 360 Wireless Headset as well. People loved not being tethered to the console with their controllers before, now they can be totally wire free when online with their friends using the new Wireless Headset. And they can be wireless to their console when tearing up the laps using the new wheel.

Here on the 360 Team we all love Xbox Live Arcade and from all the downloads of games we know you do as well. The Arcade team did an amazing job in improving their part of the dashboard this release. Being able to auto-download new titles….seeing your friends scores from the Arcade page….improving the enumeration speeds, are all part of the improvements in this area. We’re really proud of how well Arcade has done since launch but now we get to look forward to the games you guys may create via XNA Express. We worked closely with the XNA team to ensure support was in this release for developing your own games and running them on a retail Xbox 360 console. I’ve seen some of the really cool games being developed on XNA Express that have just blown me away. Enthusiasts and hobbyists around the world have been anxious to develop games on a next-gen console, and now they can.

For Your Lifestyle, we decided to focus heavily on video with this release. One of the ‘loudest’ feedback items we heard over and over was around not being able to stream videos unless you had a Windows Media Center Edition PC. I can’t even begin to count how many conspiracy theories there were around why this limitation was in place. With this update we can now dispel all those theories. We are now streaming videos from your XP / Vista PC and you can even play them back from USB 2.0 drives or data discs if you’d like. I know we are going to get a lot of feedback on the codec support we provided with this release. Let me save everyone the trouble….we know that WMV is not the only video format out there….we know that people want more choices…. and we know folks will want other codecs like H.264 / Mpeg4 / Divx / etc. Our approach from launch day last year is that we listen to constructive feedback and while I can’t promise anything for the future, I can promise that we will listen and will improve our system software over time. Some things are just not doable because of legal or licensing issues, but where possible we really try to drive new digital entertainment experiences for your lifestyle. Additional codec support is already something we’re thinking of for the future.

In addition to the streaming video support, we spent a huge amount of time getting the Xbox 360 HD DVD Player support baked into the system. I’ve been playing movies on my final production HD DVD unit and I’m amazed at the picture quality and interactive features built into the HD DVD movies. I hope everyone else gets a chance to the player out. Once you’ve gone HD, you just can’t go back!

We also worked closely with our co-workers in Zune to make sure the experience with a Zune device is handled really well on the Xbox 360. We expect that streaming videos, music and pictures will be popular with folks and I look forward to increasing the support between the two devices. Also with the Zune software on your PC you can stream AAC encoded files to your Xbox 360, something that wasn’t possible prior to this release.

With this release out the door, we’ll take a step back, collect our breaths and start to get ready for the next one. Post your feedback because we love to hear about how you’d improve and make this system better. We believe that incredible software and world class services are what make us stand out in this next generation. Your feedback guides us on what to improve or add.

Now it’s time to find some time for in-depth ‘product testing’ on some of the new games coming out. I’ve had a chance to play the final version of Gears of War and Viva Pinata, and both of them are amazing. I’m really looking forward to Rainbow Six: Vegas, as I had a chance to meet the dev team and help them integrate the Xbox Live Vision into the game about 11 months ago.

Thanks everyone,

Daryl Welsh (GT: IndieGames)
