Digital Video Encoder
Bt860/861
High-Performance Multisource Video
for a Wide Range of Systems
Conexant鈥檚 Bt860 and Bt861 are multiport digital video encoders
with pixel synchronization and per-pixel blending capabilities.
The three 8-bit YCrCb data ports allow for a variety of video
and graphics overlay configurations useful in video set-top box
applications. The Bt860/861 is designed specifically for video
systems requiring the generation of simultaneous composite,
S-video (Y/C) and either component YUV or RGB (SCART)
video signals.
High-performance video combined with the right set of features
make the Bt860/861 a versatile device for almost any video
system. 10-bit DACs provide the clear, lifelike video required for
modern satellite and cable television set-top boxes, Super VCD
and DVD players, PC add-in cards, video conferencing systems
and digital cameras. Several power conservation modes extend
portable system battery life and help reduce system heating.
New televisions and media which make use of wide screen 16:9
aspect ratios are also supported by the Bt860/861 to provide the
best flexibility, performance and functionality.
