AVS Part 1System
Chinese Information technology - Advanced coding
of audio and video
  • CUI BIN
  • AVS team of the MPL at UTA

2
AVS comprises 10 parts
  • Part I System
  • Part 2 Video
  • Part 3 Audio
  • Part 4 Compliance Tests
  • Part 5 Reference Software
  • Part 6 Digital Rights Management
  • Part 7 Mobile Video
  • Part 8 Transmission of AVS by IP Network
  • Part 9 Format of AVS
  • Part 10Mobile Audio Speech

3
AVS part 1
  • Part 1 of AVS addresses the combining of one or
    more elementary streams of video and audio
  • Convert data into single or multiple streams
    which are suitable for storage or transmission.

AVS System
5
AVS Bit-streams
  • ES
  • Elementary Stream
  • PES
  • Packetized Elementary Stream
  • TS
  • Transport Stream
  • PS
  • Program stream

6
PES
  • PES is an abbreviation for packetized elementary
    stream.
  • PESs syntax and semantics are used to
    encapsulate the audio and the video elementary
    stream information

PS ( Program Stream)
  • The PS is designed for use in relatively
    error-free environments
  • PS packets may be of variable and have relatively
    great lengths

13
TS ( Transport Stream )
  • The Transport Stream is designed for use in
    environments where errors are likely
  • The TS combines one or more PES with one or more
    independent time bases into a single stream
  • TS packets are 188 bytes long

Switch of PS and TS
  • PS and TS can be interchangeable with each other
  • Switch according to the public interchange format
    of PES Packet
