General Description
The AK8855 decodes the NTSC, PAL Composite Video signal into Digital code. Outputs are ITU-R BT. 601 Level compatible Y, Cb and Cr signals. Decoded results are scaled to QVGA/CIF sizes etc..
Output interface is camera-interface in ITU-R BT.656-alike output format. When such information as Closed Caption, VBID, WSS are encoded on the Video signal, each code can be read out externally.
When the Macrovision signal is super-imposed, its information can also externally be read out.
Features
• NTSC-M / PAL- B, D, G, H, I Composite signal decoding process
