Not exactly true; the DVD Forum has approved only certain physical carriers for encrypted digital interfaces, and those are spelled out in Forum documents as 1394 and (think it was..) USB. SPDIF as a legacy medium was never allowed; however Meridian has gotten around the issue in a proprietary fashion of their own. The DVD Forum permits proprietary digital interfaces if they pass muster with the forum.
Analog pass-thru and SACD/DVD-A mystery
From what I understand SACD/DVD-A players will require the receiver/pre-processor support analog pass thru. They, its claimed, won't work with the digital inputs accepted by the latter systems today (and fed by the CD and DVD players).
Why is this so? What is blocking the SACD/DVD-A players from outputing digital signals (like their CD/DVD ancestors) so they can plug into existing pre-processors?
Can we expect, say over 2-3-5 years, to see SACD/DVD-A players output digital signals?
