Do you want DVD players with DTS-HD capabilities to play Blu ray discs? And with DTS function, can not play?
I think you have to change this question: is it necessary to have DTS-HD enabled Blu ray players to play Blu ray discs? And with DTS function, can not play? (the DVD I am when I am with you misspoke, because the DVD machine can not play Blu ray disc Bluray is the basic common sense).Well, I answer you this way: first of all, DTS-HD is "DTS compliant". What does that mean, that is, only DTS decoders can decode DTS-HD tracks (of course, only DTS effects)?.Second, the average Blu ray disc has multiple sound tracks, such as Dolby, digital DD5.1, Dolby, TrueHD, DTS-HD, LPCM, and so on. You can't decode one sound effect or another one, which doesn't affect the playback of the disc.
Third, even if all the audio formats do not support, you can also use the source code output to connect to the external decoder (such as decoder power amplifier) to achieve audio decoding playback. Moreover, many enthusiasts prefer to use this method, they believe that the built-in decoder does not work, it will affect the quality of sound. In the ten thousand step, even if there is no sound, the image is always there. Ha ha, if you are touching 1 deaf people, he looks happy. Can you say that this is not allowed to play?
Blu ray discs will, of course, be played by Blu ray players, which cannot be played by DVD. DTS and DTS-HD are digital audio formats, and it doesn't matter whether you can play Blu ray discs or not.
