UPD61051 Datasheet, PDF (1/106 Pages) NEC – MOS INTEGRATED CIRCUIT MPEG2 AUDIO/VIDEO ENCODER

DATA SHEET
MOS INTEGRATED CIRCUIT
µPD61051, 61052
MPEG2 AUDIO/VIDEO ENCODER
The µPD61051 and µPD61052 are LSIs of MPEG audio and video encoding, decoding and transcoding.
The µPD61051 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 µPD61052 has a Dolby™
Digital Consumer Encoder in addition to the µPD61051.
The µPD61051, 61052 are the optimal choice for consumer digital video recording replay equipment to process a
MPEG.
