PD61051, 61052

MPEG2 AUDIO/VIDEO ENCODER

The

碌

PD61051 and

碌

PD61052 are LSIs of MPEG audio and video encoding, decoding and transcoding.

The

碌

PD61051 has MPEG2 video encoder, MPEG audio encoding DSP, 32-bit RISC CPU, video input/output unit

which contains a processing filter and a time base corrector (TBC), and MPEG system layer which contains the

multiplexer and de-multiplexer. It combines with 64 M or 128 Mbit SDRAM and it uses. The

碌

PD61052 has a Dolby鈩?/div>

Digital Consumer Encoder in addition to the

碌

PD61051.

The

碌

PD61051, 61052 are the optimal choice for consumer digital video recording replay equipment to process a

MPEG.
