µPD61151, 61152
MPEG2 AUDIO VIDEO ENCODER LSI
µPD61151 is a LSI of MPEG audio and video encoding , decoding and transcoding . µPD61151
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 collector, and MPEG system layer which
contains the multiplexer and de-multiplexer. It combines with 64M or 128 M bit SDRAM and it uses.
µPD61152 has a Dolby Digital consumer encoder (DDCE) in addition to µPD61151.
µPD61151/2 is the optimal for portable consumer digital video recording replay equipment to
process a MPEG.
