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
