PCI analog/DVB-T stereo TV receiver

General description

This low-profile PCI card for a hybrid TV receiver supports all video standards used in analog cable/terrestrial (PAL/NTSC/SECAM) and digital terrestrial (DVB-T) markets. It is built around the proven SAA7134 video and stereo decoder.

Background information

This design leverages the highly integrated NXP video decoder SAA7134 to significantly reduce the BOM in hybrid TV applications. On a single chip, the SAA7134 handles analog TV video and stereo decoding, Macrovision copy protection detection, and MPEG-2 transport stream capture and supplies a PCI bus mastering interface for high-speed I/O to other key components.

Software-based MPEG decoding and demultiplexing dramatically reduces the cost of digital broadcast reception in PCs and other PCI-based devices. Ideal for analog and digital TV reception, this design is also a cost-effective foundation for implementing sophisticated TV-centric features such as data broadcasting, time-shift recording, video editing, broadband Internet reception, and emerging MHP applications.
