Digital Audio in Early HD Disc Players
by henningThe previous article points out what formats are mandatory and what formats are optional in the BD and HD DVD formats. What it doesn’t discuss (though you could read it at TWICE) was the players themselves, and what they support.
Dan Ramer over at DVDFILE has been thinking about it, and doesn’t like what he sees. “The really bad news is that, with the exception of PCM, the initial Sony player will not support advanced CODECs either by decoding with its internal decoder or by outputing those digital bit streams for external decoding. Until HDMI 1.3 becomes available, you will not be able to send the bit streams for the advanced CODECs to an external decoder.”
Dolby Digital Plus, DTS HD, Dolby True HD, and DTS HD Master are all optional formats in the BD spec. These are all superior formats to standard DD 5.1, and the new Sony BD player will pass none of them out on a digital output. And if I read things correctly, it won’t even decode them to analog for you either.
For now, the digital part is no big deal. No receiver or pre/pro in existence today can decode these formats, as far as I know. But many receivers and pre/pros have analog inputs. So it would have been nice if the Sony player could at least output the high-fidelity soundtracks in analog. But that’s not the case.
One more reason to wait things out…
