Bt878/879 Single-Chip Video and Broadcast Audio Capture for the PCI Bus The Bt878/879 is a complete, low cost, single-chip solution for analog broadcast signal capture on the PCI bus. The Bt878/879 takes advantage of the PCI-based system’s high bandwidth and inherent multimedia capability. It is designed to be interoperable with any other PCI multimedia device at the component or board level. The Bt878/879 has all the video capture features of Bt848A, plus integrated BTSC stereo decode, and FM radio capture data processing. The DMA capability is enhanced to allow for low latency, digitized audio stream transport. The chip enables dbx-compliment stereo, TV, FM radio, and base-band video and audio as input sources. In addition, the chip simplifies the computer/broadcast signal interface down to a single PCI connection.
