BT860KRF概述

Color Signal Encoder, CMOS, PQFP80, MQFP-80

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.
