[opendtv] Re: Defining Visions: They've Done It To Us Again. . .???!!!

HDMI supports 1080@24p. Refer to EIA-CEA-861B for all the
video formats that HDMI can transport. A couple of Sony hi-end
digital projectors will accept the 1080@24sF variant.

IEEE1394 can deliver 8 channels of uncompressed audio with
content protection. In fact, it's the only digital interface currently
allowed for SACD. Installed base is not huge, but it's on pretty
much all Japanese hi-end receivers and DVD players.
