8. Video Capture
8.1 Video Capture function
8.1.1 Input data Formats
The digital video stream of ITU RBT-656 or RGB666 format conformity is inputted (for details refer
to 8.5 external video signal input conditions).
8.1.2 Capturing of Video Signal
“Coral-PA” becomes effective when VIE of a video capture mode register (VCM) is 1, and it is
CCLK. Synchronizing with a clock, video stream data is captured from 8-bit VI pin or 20-bit RGB
input pin.
8.1.3 Non-interlace Transformation
Captured video graphics can be displayed in non-interlaced format. Two modes (BOB and
WEAVE) can be selected at non-interlace transformation.
- BOB Mode
In odd fields, the even-field raster generated by average interpolation are added to produce one
frame. In even fields, the odd-field raster generated by average interpolation are added to produce
one frame.
In order to choose BOB mode, while enable vertical interpolation in VI bit of a VCM (Video Capture
Mode) register, the L1IM bit of L1M (L1-layer Mode) register is set as 0.
- WEAVE Mode
Odd and even fields are merged in the video capture buffer to produce one frame. Vertical
resolutions in the WEAVE mode are higher than those in the BOB mode but raster dislocation
appears at moving places.
In order to choose WEAVE mode, while disable vertical interpolation in VI bit of a VCM (Video
Capture Mode) register, the L1IM bit of L1M (L1-layer Mode) register is set as 1.
