A majority of the consumers in this market have been spoilt for choices since they come from a HTPC background, and stress their media streamers to the limit (even beyond the officially supported specifications). Sometimes, they are pleasantly surprised by some available unadvertised feature (like the TrueHD bitstreaming in WDTV Live, which wasn't part of the initial specifications). Most of time, though, various limitations start showing up, both in terms of hardware capabilities and software support. These are dealt with in the reviews of the individual products. The end consumer needs to look at his requirements before choosing a media streamer. In addition, reviews on the net should cater to what the market really wants, and not rehash the marketing speak from the companies. Anandtech is working on creating a comprehensive suite of test streams to identify the capabilities as well as shortcomings of the various media streamer platforms. Towards this, we have identified the following features which differentiate the various platforms, both from a hardware as well as software perspective.

  1. Audio & video container support (MKV / MP4 / MOV / AVI / FLV / WebM etc.)
  2. Video codecs (H264 / VC-1 / Real Media / VP8 etc.)
  3. Audio codecs (Dolby / DTS / FLAC / Ogg Vorbis / WMA Pro / HD Audio - Decoding / Bitstreaming)
  4. Multiple subtitle formats
  5. Interlaced video streams in different codecs
  6. Specific video & audio codec quirks (such as weighted P-frame prediction & unreasonable number of reference frames for H264)
  7. Maximum video & audio bitrate
  8. Maximum video frame rate

Readers are welcome to suggest other aspects which need to be added to this test suite.

While this roundup article may not have an analytical conclusion, I will bring it to a close by listing out the platforms which we will closely follow in the coming days with respect to the above features:

  1. Atom + Ion / Ion2 [ x86 + Nvidia custom HD decode engine ]
  2. Mediatek 8520 Series [ ARM11 + Mediatek custom HD decode engine ]
  3. Sigma Designs 86xx Series [ MIPS + Sigma Designs custom HD decode engine ]
  4. Realtek 1073/1283 Series [ MIPS + Realtek custom HD decode engine ]
  5. Nvidia Tegra2 [ ARM Cortex-A9 + Nvidia low power custom HD decode engine ]
  6. Samsung S5PV210 [ ARM Cortex-A8 + Samsung low power custom HD decode engine ]
  7. Telechips TCC89xx [ ARM11 + Chips&Media Boda series HD decode engine ]
  8. Intel CE4100 [ x86 + Intel custom HD decode engine ]


Stay tuned for exclusive analysis of the capabilities of each of the above platforms from Anandtech in the near future!

    Could I put in a request that you test subtitle languages that are Right to Left oriented, like Hebrew? there is quite a market for HTPC and Media Streamers in the middle east but companies support for RtL languages has been less than stellar and is something that often even their technical support finds hard to give a straight answer about.

    I would also test network capabilities. Support for wireless or wired, limitations, connection stability and so on.
    I would say most people buying such a device will sooner or later also get a NAS.

    Personally I have a WD TV Live and it's fine.But it has it's issues. One beeing that it sometimes has trouble connecting to the network. Another thing is that some content from youtube is blocked. You get a message similar to:
    "This content can not be watched from TV attached devices."
    This is pretty annoying because it is no mentiond that youtbe access i limited...
    -> one thing that speaks for a real HTPC.

    beginner99, Thanks!

    We definitely plan to test the networking capabilities, and present it in the review. The only problem we will need to work around is the fact that the network performance is highly dependent on the setup and environment. So, one thing which works in the reviewer's home perfectly, might not be very stable in someone else's home. Of course, we will be keeping an eye out on the various forums to get the various users' experience and make those observations play a small role in our review.

    By the way, my WDTV Live experience is also very similar to yours, and that is the main reason I am unable to get rid of my HTPC :)

    For HD content you will def. need 50+ sustained mbps. I find that even my netgear WNDR3700 based wireless stutters on High Def, I just wired everything and now it's silky smooth.

    I think the devices should be reviewed in their own right, with no networking limitations, then a general review of how wireless works on media streamers ( unless you find one that performance unusually well or poor)

    Also you might think about looking at software media servers like twonky and tversity and others. With Twonky and WD Live, through the twonky software on your server ( computer) you can tell the WDlives what to do, for instance, play music in the bathroom, see what each device is playing, Play the same music through out your home.

    "For HD content you will def. need 50+ sustained mbps"

    For non-recoded BD rips perhaps, but many users will not run into this limitation, at least not in the current state of things. I've tested hundreds of 1080p mkv/H264 rips and typical bitrate is in the neighbourhood of 20mbps (variable, peaking as high as 40).

    I don't stream a lot of HD over wireless, but with a good 54mbps connection I've found 720p to work well, while 1080p is more hit and miss.

    Yea I'm talking about demuxing and remuxing a Blu Ray and playing back TrueHD which is my preferred way of getting HD content. I guess if you reencode it at 720 P you would be ok. Now, I'm way more picky then most so to get acceptable quality encoding HD takes around 5-10 hours, I have a Core I7 at 3.7ghz. So for me, forget that.

    But I just say 50mbps just to be on the safe side, you'd probably be ok with 40 but you would have no overhead.

    Don't forget the SageTV HD200. It is the only media streamer that spans all of the categories. It can act as an extender for their excellent media center software, can play almost any file format (mkv, blu-ray file format, etc) as a standalone media streamer, and can stream non-DRM internet video. I'd love see Anandtech cover it since it never seems to get any love from the media.

    Hubble70,

    Thanks for your suggestion. SageTV HD200 is based on a Sigma Designs chipset. It will probably have the same features of a WDTV Live or any other NMT, except for UI changes. We will definitely review an upcoming revision of the product if we manage to get our hands on a review unit.
  • Hubble70 - Wednesday, June 16, 2010 - link

    Yeah, its based on the old Sigma, but I find that its not the hardware that limits most of these devices, it is the software stack. Whether or not they can play ISO, full BD menus or just BD menu lite, whether you can pick a BD playlist, container support, etc. It seems to matter a lot more than the hardware in them unless you really want HD audio support which it lacks.

    And no, the HD200 is nothing like the WDTV since its primarily designed as an extender for for their media center software. And when you use their media center software you can use any UI on it that you want. There are LOTS of user created UIs and you can customize your own easily. SageMC is the most popular alternate UI. Their new version of their media center, V7.0 even allows you to install XBMC frontends on them, though this feature is in beta.

    Used as a standalone unit it is pretty similar to the WDTV live but with better file format support.

    It's definitely worth taking a better look at since it is unique among media players because it can be used as an extender, a standalone media streamer, and even as a placeshifter.

    Here's a geektonic review of the unit.

    Hi and thx for an very interesting article.

    I would like included test for playback of the format WTV which is the standard TV recording format for Windows7 / media player 12
    WMP cannot record TV shows in any other format, and i am really annoyed by my WDTV LIVEs lack of ability to playback it.
    Not that any of the competition can either though..
