4 Overview

Multiplexing is used for the encapsulation and sequence arrangement of audio, video,

data and control information such that they are adaptive to mobile multimedia

broadcast channel for transmission, see Figure 1. The audio stream, video stream

and data stream that belong to the same service will be placed in the same multiplex

sub-frame. Auxiliary information such as ESG, subscriber management will be placed

in different multiplex sub-frames. The system control information will be placed in a

special multiplex frame.

configuration table. When there is a change in information described in short time

service multiplex configuration table, the sequence number of short time service

multiplex configuration table needs to be changed; the value shall be cyclically taken

from the range 0~15, adding 1 for each update.

Sequence number for short time service configuration table update

4-bit field, indicating the sequence number of short time service configuration table.

When there is a change in information described in short time service configuration

table, the sequence number of short time service configuration table needs to be

changed; the value shall be cyclically taken from the range 0~15, adding 1 for each

update.

Sequence number for ESG update

4-bit field, reserved for ESG.

Quantity of multiplex sub-frame

4-bit field, quantity of multiplex sub-frames that are included in multiplex frame.

Length of Multiplex Sub-frame 1

24-bit length, the length of the first multiplex sub-frame in multiplex frame, unit is byte.

Length of multiplex sub-frame

24-bit length, the length of the multiplex sub-frames other than the first sub-frame in

multiplex frame, unit is byte.
