Bt829B/827B
VideoStream II Decoders
1.1.1 Bt829B Video Capture Processor for TV/VCR Analog Input
1.1.2 Bt827B Composite/S-Video Decoder
The Bt829B Video Capture Processor is a fully integrated single-chip decoding
and scaling solution for analog NTSC/PAL/SECAM input signals from TV tun-
ers, VCRs, cameras, and other sources of composite or Y/C video. It is the second
generation front-end input solution for low-cost PC video/graphics systems that
deliver complete integration and high-performance video synchronization, Y/C
separation, and filtered scaling. The Bt829B has all the mixed signal and DSP cir-
cuitry required to convert an analog composite waveform into a scaled digital
video stream, supporting a variety of video formats, resolutions, and frame rates.
The Bt827B provides full composite and S-Video capability along with horizontal
scaling. Vertical scaling can only be implemented by line-dropping.
