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) composite or Y/C (S-video) signals. The Bt856 and Bt857 are functionally identical, with the exception that Bt857 can output the Macrovision anticopy algorithm. Horizontal sync (HSYNC*) and vertical sync (VSYNC*) may be configured as inputs (slave mode) or outputs (master mode). BLANK* is an input and may be externally controlled. 24-bit linear or gamma-corrected RGB data or 4:2:2 YCrCb data may be input. The rise and fall times of sync, the burst envelope, and closed caption data are internally controlled.
