The CH7205 is a video TV encoder device for DVD
applications which accepts a digital video input signal,
encodes and transmits data through four 10-bit high speed
DACs. The device is able to generate synchronization signals
for NTSC and PAL TV standards with CVBS, S-Video
outputs, and YPrPb outputs (480i, 576i, 480p and 576p).
The device accepts data over one 12-bit (or 8-bit) wide data
port with dual edge clock data transfer for multiplexed data
(24 bit or 16 bit) through variable voltage data port which
supports 5 different data formats including RGB and YCrCb.
create outstanding video quality. Support is provided for
Macrovision
and scan converted to non-interlaced video.
In addition to TV encoder modes, bypass modes are included
which perform color space conversion to HDTV standards
and generate and insert HDTV sync signals.
