Why isn't DTS the default for HDTV programming?

So why isn’t DTS the default for HDTV? Poor marketing?

    Because Dolby has been the Industy standard since the beginning of time itself.

    Dolby labs is more supported and excepted.DTS is a great format but if you look around,nobody really cares if it is used or not.Digital in Video games,DVD's,HDTV,PPV movies all Dolby digital.

    I just picked up The Last Samurai and guess what??No DTS.

    Shame but true,

    I'm pretty sure DTS is less compressed than DD and so it would require more bandwidth to deliver.

    I bet there will be a Last Sammy DTS version eventually, "collector's edition" or some such. It's an average flick anyways.

    IIRC, DTS is 20bit/48khz, DD is 18bit/48khz.

    Yea, Dolby definately has more industry support, since the DVD spec has Dolby in it, like, you can't make a DVD w/o a Dolby track ;)

    DTS requires a lot more megabytes of data.

    The information that you have is totally incorrect. The numbrs that you quote are numbers that refer to an LPCM (linear pulse code modulation) audio signal. 20 bit/48 khz and 16 bit/ 48 khz figures that can only refer to a totally lossless LPCM signal and could never refer to either dolby digital or DTS, which are both lossey compression encodeing formats. The proper way to refer to any audio signal that has been compressed is by referiing to the speed of the audio signal measured in kbps. For example, dolby digital is rated at 384,000 bits per second for all 6 channels of sound, or a mere 64 kbps per channel. DTS does increase the data rate to 1,411,200 bits per second, or 235.2 kbps per channel. In contast, an LPCM siganl that is 24 bit/ 48 khz has a data stream of 2,822,400 bits per second, in 24 bit words. This terminology of word legth and sampling rate does not even apply to a compressed signal such as dolby digital or DTS which does not use any word length at all, it is simply a data stream.
