DigiPEG

Audio-Video MPEG-2 Full Duplex Encoder/Decoder System

This board can be used to encode/decode analog NTSC & PAL video-audio signals and broadcast them in MPEG-2 format, or the opposite.

All functions are remotely controllable via RS232, and therefore no special knowledge of programming languages is needed.

Extremely versatile and easy to use even for non-experts of MPEG technology, this board allows to develop and test your own products directly, with a multitude of possible applications.
