YCrCb or RGB to NTSC/PAL Digital Video Encoder

The Bt856/7 is designed specifically for video systems requiring the generation of 525-line (NTSC/PAL–M) or 625-line (PAL–B, D, G, H, I, N, N-Argentina) compos ite or Y/C (S-video) signals.
The Bt856 and Bt857 are functionally identical, with the exception that Bt857 can output the Macrovision anticopy algorithm.
