Bt829B/827B VideoStreamII Decoders Bt829B– Video Capture Processor and Scaler for TV/VCR Analog Input Bt827B– Composite Video and S-Video Decoder The Bt829B and Bt827B VideoStream™ Decoders are a family of single-chip, pin- and register-compatible, composite NTSC/PAL/SECAM video and S-Video decod- ers. They are also pin and register backward compatible with the Bt829A/827A family of products. Low operating power consumption and power-down capabil- ity make them ideal low-cost solutions for PC video capture applications on both desktop and portable system platforms with a 3.3 V digital I/O interface. They support square pixel and CCIR601 resolutions for NTSC, PAL, and SECAM video. They have a ﬂexible pixel port which supports a variety of system interface conﬁg- urations, and they are offered in a 100-pin Plastic Quad Flat Pack (PQFP).
