    Default Will Tata Sky switch to MPEG 4?

    Tata Sky I think was one of the first well can say successful DTH services in India, and has done very well, with its + box too.

    When do you think Tata Sky will switch to MPEG4?

    Or do you think they every will?

    MPEG 4 is just a compressed technology with the quality it provides I don't feel any change is required at present.
    In future Tata sky may switch to MPEG 4!! Who Knows:001_rolleyes:

    For going to HD, every DTH provider will have to move to H.264/MPEG4 AVC. This is not because MPEG4 is better in quality but the amount of bandwitdh required by MPEG2 in HD will be enormous. MPEG4 with its advanced and higher compression ratio will be able to do so and possibly squeeze in more channels too.

    So yes. TataSky will move to MPEG4, sooner or later.

    Tata has launched the tata sky plus which works on the mpeg4 and also supports live pause and recording

    No. You are mistaken. TataSky+ is compatible with MPEG4. So when they switch to MPEG4, these folks who are using TS+ will not need to switch the box.

    TataSky still broadcasts in MPEG2.

    Does compression bring pixelation of video quality?

    To some extent, any compressed picture will always have loss as compared to the RAW format.

    But ...

    MPEG4 is able to compress the video with the same quality as MPEG2 and the corresponding size is much smaller.

    MPEG4 being able to compress the video size might also have more impact on the video quality or does it compress the file without affecting video quality?

    Well To be more simple:
    MPEG 4 compress the file more without affecting picture quality. where as MPEG 2 compress file less. But in both the case Picture quaity is remains same.

    So MPEG 4 and MPEG 2 have same Picture and Sound quality.

    There is a caveat however.

    It all depends upon how much one wants to compress. A video can be MPEG4/H.264 but the frame size could be compressed for various target devices. For instance if the target (viewing) device is standard 4:3 TV, then the frame size will be 640 x 480. If the target device is an ipod then the size will be 320x240.

    True HD is 1980 x 1080 pixels.

    So even though all are MPEG4, the quality will differ depending upon the frame size selected.

    Should it really matter to us(TS customers) in anyway!!?

    It is a sure boon to TS as it can use up its bandwidth efficiently.. But since there is no enhancement in quality and probably the price being the same, i feel no necessity of keeping track of its switch over.. :sleep:

    PS-its just my point of view..:rolleyes1:
