GENERAL DESCRIPTION
The SAA7120; SAA7121 encodes digital YUV video data
to an NTSC or PAL CVBS or S-Video signal.
The circuit accepts CCIR compatible YUV data with
720 active pixels per line in 4 : 2 : 2 multiplexed formats,
for example MPEG decoded data. It includes a sync/clock
generator and on-chip DACs.
Macrovision Pay-per-View copy protection system rev.7
and rev.6.1 as option.
This applies to SAA7120 only. The device is protected
by USA patent numbers 4631603, 4577216 and
4819098 and other intellectual property rights. Use of
the Macrovision anti-copy process in the device is
licensed for non-commercial home use only.
Reverse engineering or disassembly is prohibited.
