We went for a test drive AVOV VOXIO 2 - below I will do something like review of this particular device , but I advise you to read it if you are interested in principle from the combination Android + TV because most things are valid for all devices of this class .
Parameters sounded tempting , and we hoped to be able to run STB emulator and we can use it as a set - top box for TV. Unfortunately will not happen . Here disadvantages , most of which apply to all similar Android - based devices .
- Although HDMI output can operate up to 1080p, Android kernel supports up to 720p. We have not found a HDMI stick or STB into android whose kernel is Full HD, this was no exception . It should try to unofficial ROM. We will find and test later
- Hardware Video Decoder does not support deinterlacing. This is no exception - we have not come across with Android hardware maintenance of deinterlace, and quad processor is not sufficient to allow software to decode HD channels . STB emulator works properly with embedded software player, but pleaded an SD television . For HD should include hardware acceleration , which automatically leads to the indentation caused by lack of deintrelace.
It notes that there is no television channel that is progresive (1080p). Even full-hd television , every one , without exception, are 1080i (interlaced). Interlaced means the picture arrives at a field two - one with the even lines and then another with odd . This is from the times of CRT and it is unclear when it will change.
If your TV is not CRT (Cathode ray tube) , someone must become the image of the "i" in "p" (de-Interlacing). If the connection device - TV is 1080i, this is one TV , but if 1080p - the device does deinterlace before giving the signal to the TV. Yes, but Android boxes do not support 1080i output , and even TV does deinterlace, if the input comes 1080p, so in this case no one converts the image of the two television a field in a single frame. When moving , the images appear as cut comb.
By curiosity spent image receiver in the famous DCDi processor Faroudja (Harman-Kardon), but non- interleysnat Deteriorated image could be fine , stay , rugged . I.e. even if you have a TV with integrated high-end video processor , spoiled image will remain broken. Perhaps the untrained eye will not see the difference , but for us in the category of " not going to watch "
As I said above two defect at least until proved inherent in all Android devices that have passed through our hands ( tablets, sticks , STB), including original MAG 260 .
AVOV VOXIO 2 offers a way for audio playback - HDMI. Via HDMI in theory can play Dolby Digital (AC3) and DTS 5.1 mode pass-through, but in practice it proved extremely difficult . After much trial and error proved , HDMI pass multi-channel audio, ONLY if used H / W codec , but not H / W +. If the application can choose between the H / W and H / W +, may be able to spend 5.1 audio, but if not - do not try , will not happen.
Conclusion: it is still early for Android - based TV set - top boxes . Games and mltimediya - maybe it ( it 's the right word) , but television - a firm NO . In 2015, we will continue to watch TV with specialized devices for this purpose if we want to have a quality picture.
Here is information on what is deinterlacing, and why it is important how the picture looks if not made or made poor :
I will be happy to hear the opinion of David from team's AVOV . Please people who have no idea what's in the topic does not take a position.Code:http://www.100fps.com/
