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

(2) Encoding and Transcoding system
2.3.2
encoder based on MPEG2-TS/PS.
2.3.3
(1) MPEG2-TS
(2) MPEG2-PS
It stamps SCR, PCR, DTS and PTS after multiplexing streams that are from the video encoder and the audio
Partial TS can be made by forming SIT packet from PSI and SI data of base on DVB.
It is possible to multiplex the packet that inputted from the host CPU interface.
It can output the signal, which generates the pulse wide modulation (PWM) with comparing PCR/SCR of the
stream and system time clock value, for making the reference clock of the system.
Using the PID filter corresponding to 16 PIDs, It separates MPEG2-TS to one video stream, two audio streams,
and two user data streams. Internal CPU extracts section data in PSI and SI of base on DVB.
With the stream ID filter, it separates MPEG2-PS to one video stream, one audio stream, and two user data
streams.
