Region Coding In an attempt to control the distribution of video
discs, the DVD Forum has designated eight

horizontal pixels by the number of vertical pixels.
The resolution of a DVD is 720x480 for
NTSC discs
and 720x576 for PAL discs. Scaling must be used to
convert this resolution to the resolution of a Fixed
Pixel display. The horizontal resolution of a CRT
(i.e., analog) is somewhat ambiguous, as there are no
discrete pixels used in this technology.
Scaling Scaling is the process of converting a video signal
from one
Resolution to another. As with any type of
signal processing, care must be taken to ensure that
the signal is not degraded by the processing itself.
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 .
UOP Video disc formats allows the disc itself to send
commands to the player. A User Operation
Prohibition is a disc-based command that tells the
