what is really weird is that most of the BD releases have a DTS-HD audio track in it !
but so far none of the players are able to handle this ... pretty lame for a format start ...
Panasonic has announced plans to add DTS-HD MA decoding in a software update, coming in March. Sony is also expected to add DTS-HD MA decoding to the PS3 at about the same time.
so let's say the PCM uncompressed audio track is kicking a$$, why bother putting DTS-HD audio track in BD releases ????
Because of a dirty little secret...
The "dirty little secret" that many in the BD camp don't like to talk about...is that you aren't getting master audio or "HD audio" at all with most LPCM tracks. Instead, you are getting compromised
, lower-fidelity 16/48 tracks downconverted from the 24/48 masters. The LPCM tracks on all but four Blu-ray titles are lower-fidelity 16/48 tracks downconverted from 24/48 masters.
According to DTS, even their lossy
DTS-HD audio @ 3.0Mbps noticeably exceeds the quality of the current 16/48 LPCM tracks.
Virtually every studio including LPCM right now is doing it soley for marketing purposes. They know it is inferior to the lossy 24/48 DTS-HD and lossless 24/48 DTS-HD / TrueHD tracks that require less space
on disk, but they do it anyway to sell you "HD Audio" that is compatible with your legacy Blu-ray players. Don't be surprised if they try to sell you a "special edition" re-release in a year or two with a full 24/48 track on a BD50.
FOX has taken the right approach with an eye toward the future. They include full, master quality 24/48 DTS-HD MA lossless tracks with all of their titles. Thanks to lossless compression, these 24/48 master quality tracks consume less space on every disk than lower-fidelity, downconverted 16/48 LPCM tracks. Current players can't decode them, but within 12 months, you won't be able to buy a player without full DTS-HD MA decoding, and most Blu-ray players in customers' hands (i.e. PS3s, Panasonic's BD players, among others) will support it within a matter of months. In the meantime, you get a 20-bit DTS-ES core track @ 1.5Mbps for backward compatibility that rivals 16-bit LPCM in quality.
Quite frankly, if you buy a player without DTS-HD MA or an upcoming DTS-HD MA upgrade, you are getting a player with inferior audio output quality. Based on comments from a Sony representative on the insiders thread, they have no intention of ever using LPCM at full 24/48 quality on a BD25 release, so if master quality audio is something you want, then you need a player with DTS-HD MA and Dolby TrueHD decoding.
