be perfectly capable of doing the Master Audio as well. I don't think you'd really get one without the other.
Actually, the decoding model is completely different.
With a lossy codec, like DTS-HD, there is no need to achieve a bit perfect decode, and some sort of decode tolerance is built in to codec.
First off, to decode DTS-HD MA, a decoder must be able to deal with a much higher bandwidth.
Secondly, the core track must be perfectly extracted, since the extension contains only the data that, when added to the core decode, will result in a lossless decode that matches the PCM that was present on the encoder input.
This probably adds a secondary pass which increases decoder complexity.
That core decode then must be mixed with the lossless extension...
Even though DTS-HD and DTS-HD MA use a core and extension model, they are two different animals to decode..
Look at the Panasonic BD10.. does TrueHD (easy to decode) and DTS-HD only... the only player that is currently decoding MA is the Denon, and it is using the DSP section from one of their receivers to do it... I suspect the new Panasonic's and Sony's will use a new SOC to achieve in-player decoding.....
I think it is pretty safe to say that this player has neither the horsepower or silicon to do the decode.
