Bt864A /865A
Digital Video Encoder
High Performance YCrCb to
NTSC/PAL Digital Video Encoders
Conexant’s Bt864A and Bt865A are designed for video systems
that require the generation of high-quality composite, Y/C
(S-video) or RGB (SCART) video signals from an 8- or 16-bit YCrCb
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 pin-compatible and functionally
identical, except the Bt865A can also output the Macrovision™
version 7 anticopy algorithm. Either master or slave mode
operation may be implemented to provide the highest video
performance when interfaced with any MPEG decoder. CCIR 601
or square pixel video signals may be input to provide maximum
flexibility in the system architecture.
