Bt868/Bt869
Flicker-Free Video Encoder with Ultrascale
TM
Technology
The Bt868/869 is specifically designed for video systems requiring the generation of
high-quality flicker-free composite and Y/C (S-video) signals from various YCrCb or
RGB digital streams. The Bt868/869 accepts any input format from 640 x 480 to
800 x 600 resolution.
The Bt868/869 uses Conexant鈥檚 UltraScale鈩?technology to provide the most
advanced vertical and horizontal scaling necessary for the display of non-interlaced
data on interlaced devices such as the TV. The UltraScale鈩?technology converts the
lines of input pixel data to the appropriate number of output lines for producing a
full-screen, high-quality image.
The Bt868/869 performs 5-line vertical filtering, which includes poly phase
interpolation scaling for overscan compensation and flicker filtering. Horizontal
scaling for overscan compensation is achieved by altering the encoder clock
frequency. This approach preserves all of the high frequency components of the
input signals, which are essential for the highest quality display of text intensive
images such as web pages on TVs. The amount of flicker filtering and overscan
compensation is programmable.
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). Bt868 and Bt869 are functionally identical, with
the exception that Bt869 can output Macrovision Level 7.0 anticopy algorithm.
