DD+ question

gedlee · 19th November 2009, 07:11 AM

On another thread it was stated that SPDIF cannot pass out DD+ or any of the HD formats available on BlueRay. If this is the case is there any way to get these higher foirmats from a blueray player in a PC? The players only seem to use SPDIF pass through.

Comments?

That's correct. SPDIF is too low bitrate to support E-AC3, but all E-AC3 streams -should- have an embedded legacy AC-3 stream for output over SPDIF.

Any HDMI output which is HDMI 1.3 or 1.4 compatible should be able to output E-AC3, but whether that's the case for any current HDMI-output graphics cards, I don't know.

Well thats now the question. If I send the HDMI output from the video card to a receiver that is HDMI 1.3 compatible will that strip off the E-AC3 and then pass on the video to the projector just as it is now?

It SHOULD, but I think some/most HDMI graphics cards actually have too many smarts in the way to just pass the stream untouched. Most seem to emulate an SPDIF output which is then muxed with the DVI video to produce HDMI.
