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.
