ES7010 and ES7011

MPEG2 AVEncod e r

Prod u ctBrie f

The ES7010 and ES7011 are MPEG2 audio video encoders. They consist of a video encode/

transcode unit, audio DSP engine, a 32-bit RISC CPU, a video input/output unit and a system

control unit. The devices uses either 8MB or 16MB of SDRAM depending on the functions. This

device is the optimal choice for consumer digital video recording and playback needs.
