• Manufacturer Part Number: UPD61052
• Description: MPEG2 Audio / Video Encoder
• Manufacturer: NEC

2.3
combining the multiplexer and de-multiplexer, it does the transcode which is accompanied by MPEG2-TS⇔MPEG2
PS conversion.
2.3.1
(1) Encoding system
22
This LSI multiplexes and/or de-multiplexes Audio and video streams based on MPEG2-TS/PS and MPEG1. By
When the encoding system operates, it uses the clock input to STCLK that is generated with the 27 MHz
oscillator.
Audio master clock is made with 27 MHz of STCLK, and then Audio synchronizes to STC.
