In-Depth Information
Fig. 26.32. shows the MOT data structure. The files to be transmitted,
the slide show or the HTML data are transmitted in the payload segment of
an MOT packet. The MOT packet plus header is inserted into the payload
segment of an MSC data group, the MOT header coming first followed by
a CRC checksum. The entire MOT packet is divided into short constant-
length packets of the packet mode. These packets are then transmitted in
subchannels.
