SoG Sync-on-Green refers to an RGB video connection
that has the sync (timing) signals combined with
the green signal. Only three wires are required for
this connection, compared with five wires for an
RGB+HV video connection.
S/PDIF The Sony/Philips Digital Interface Format is
commonly used to transmit digital audio
information from a source (such as a DVD player) to
a receiver (such as an audio processor). The
connectors used for S/PDIF are common RCA
(Cinch) connectors. Also see AES/EBU.
S-Video An Interlaced video signal that has two components;
one for brightness (black-and-white) information
and another for color information. Performance is
much better than Composite video, but due to
bandwidth restrictions, has less color detail than
does interlaced Component video.
UOP The DVD format allows the disc itself to send
commands to the player. A User Operation
Prohibition is a disc-based command that tells the
DVD player to ignore commands issued by the user.
For example, some DVDs will display the FBI
warning at the beginning of the disc and issue a
UOP that temporarily disables most user
commands.
YCbCr A digital Component signal, where Y is the brightness
(black-and-white) signal, and Cb and Cr are the
color signals. The picture on a DVD is stored in
YCbCr format, as it requires less storage space for a
given visible resolution than does RGB.
