The Bt864A/865A is specifically designed for video systems requiring the generation of composite, Y/C (S-video) or RGB (SCART) video signals from an 8- or 16-bit YCrCb digital video stream. Worldwide video standards are supported including NTSC-M (N. America, Taiwan, Japan), PAL-B,D,G,H,I (Europe, Asia), PAL–M (Brazil), PAL-N (Uruguay, Paraguay) and PAL–Nc (Argentina). The Bt864A and Bt865A are functionally identical, with the exception that Bt865A can output the Macrovision level 7 anticopy algorithm.
