STD-B32:Video Coding, Audio Coding and Multiplexing Specifications for Digital Broadcasting(Fascicle 2)

[STD Number]ARIB STD-B32
[Standard Name]Video Coding, Audio Coding and Multiplexing Specifications for Digital Broadcasting(Fascicle 2)
[Enactment Date]2001/5/31
[Version]　　　　3.11
[Revision Date]2018/7/26

[General Description]

This standard specifies video signal and coding system, audio signal and coding system, and multiplexing system of transmission signal for digital broadcasting, and this standard comprises the following three parts.

Part 1: Video Signal and Coding System
Part 2: Audio Signal and Coding System
Part 3: Signal Multiplexing System

Part 1 specifies video input format (video signal based on HDTV and SDTV, sampled value of signal, scanning direction, video signal parameters), video coding system based on MPEG-2 Video standard and MPEG-4 AVC standard (combination of motion compensation prediction coding system, discrete cosine transform system, and variable length coding system), compression procedure of video, transmission procedure and signal structure after coding, and restrictions of coding parameters.

Part 2 specifies audio input signal (sampling frequency, bit number of quantization, etc.), audio coding system (combination of time frequency transform coding system and psychoacoustic weighted bit assignment), compression procedure and transmission procedure of sound, restrictions of audio coding parameters, and lossless audio coding system (audio coding system and transmission procedure).

Part 3 specifies multiplexing system (transmission by TS packet (coded signal, transmission control signal, emergency alarm signal), IP packet transmission by TS packet (coded signal, transmission control signal, emergency alarm signal), IP packet transmission by TLV packet (coded signal, transmission control signal)), multiplexing signal format (PES packet, section form, TS packet, IP packet, TLV packet, ULE packet, compression IP packet, structure of transmission control signal, structure of descriptor, structure of identifier, structure of related information and transmission procedure).
