Technical Description Preliminary

The MPEG-2 A/V Encoder Card is part of a family of powerful-single-board solutions designed to compress audio and video for broadband network, home network and security applications. Its main application is video over IP, enabling the delivery of value-added services such as streaming video with multicasting technology, video surveillance and video conferencing. The card, which comes in 2 configurations: low latency with a bit-rate up to 8Mbps and full DVD quality bit-rates with higher latency, is shipped with device drivers and sample application code for easy installation, setup and operation. The MPEG-2 A/V Encoder Card creates an efficient environment for rapid prototyping and reduced time-to-market.
