Next Generation DVD Processor

Video Input/Output Interface
In addition to the six 10-bit video DACs, the
CS98200 provides a separate Digital Video In-
terface that will give you flexible and powerful
means of outputting digital video data to exter-
nal devices in CCIR601/3 and CCIR656 formats.
The interface directly supports NTSC/PAL vid-
eo encoding, in both master and slave synchro-
nization configurations. The internal frame
buffer format could be 4:2:0, 4:2:2, YUV655,
RGB565 and RGB555.
The CS98200 also features an NTSC/PAL video
decoder input interface. The interface accepts
CCIR601, CIF, and QCIF formats, out of many
TV decoders on the market. The video processor
also allows overlay of multiple video planes
(main video / video input / picture_in_picture
/ on-screen display).
The Video Input Scaler (VIS) module inputs 8-
bit digital video data from a camera or
PAL/NTSC decoder and simply dump all the
data to DRAM. The scaled image, with a border,
can be overlaid anywhere on the screen into a ½
or ¼-screen sized window by the Picture in Pic-
ture (PIP) module.
An alternate method of using the Video Input
function is to input a full sized picture and
present it on the screen full size (bypass mode).
In this mode, the PIP module can place full mo-
tion DVD images in the small window. An inter-
nal glitch-free mux can switch the video
processor clock source from the internal clock to
the Video Input clock, allowing the PIP mode to
switch back and forth on the fly, with no drop-
out.
