●Multiport YCrCb to NTSC / PAL / SECAM Digital Video Encoder
●The Bt860/861 is a multiport digital video encoder with pixel synchronization and per-pixel blending capabilities. The three 8-bit YCrCb data ports allow for a variety of video and graphic overlay configurations useful in video set-top box applications. The Bt860/861 is specifically designed for video systems requiring composite, Y/C (S-Video), and simultaneous component YUV or RGB (SCART) video signals. 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),
●PAL-Nc (Argentina), PAL-60, NTSC-443, and SECAM. The Bt860 and Bt861 are functionally identical except that the Bt861 can output the Macrovision 7.x anticopy algorithm.
