Real-Time MPEG -1, MPEG -2, and MPEG-4 Encoder

MVRD4000 is a hardware-based, high-quality MPEG-1, MPEG-2 and MPEG-4 encoding/decoding solution. Featuring software for capture and playback, MVRD4000 also includes a software development kit for programmers to create custom applications that utilize the hardware for MPEG encoding and decoding tasks.

With real-time MPEG-4 encoding capabilities, MVRD4000 can produce high-quality video streams with reduced file sizes, making them ideal for delivery over networks, e-mail attachments and for optimum storage on hard disk drives and optical media. MVRD4000 also supports Main Profile at Main Level (MP@ML) MPEG-2 encoding. When using MP@ML, the MVRD4000 delivers the high-quality video and audio MPEG-2 output required by today's video professionals for DVD authoring. In addition, MVRD4000's variable bitrate capability is one of the most effective techniques used to maintain video quality while reducing file size. With composite and S-Video inputs, MVRD4000 is scalable up to full-D1 resolution with NTSC and PAL format support.

The capture and playback application MPEGPit is included with MVRD4000. MPEGPit is provided to monitor basic operation of the MVRD4000 board and to create MPEG files, such as content files, for Grass Valley MediaEdge. MVRD4000 also features an SDK for developers to create custom applications that use MVRD4000 to encode and decode MPEG video.

The real-time analog-to-MPEG capture capability of MVRD4000 also makes it an ideal companion to Grass Valley MediaEdge, a LAN-based client / server video distribution system. When combined with MediaEdge, MVRD4000 provides real-time MPEG encoding and live stream network broadcast of high-quality MPEG-4 video.
