Channel information transmitting method and receiving apparatus

摘要

A plurality of channels can be set so as to be associated with one another and an accounting system can be changed and programs can be drawn up every channel. Only information of a PMT of a program number of a main channel is described in a PAT as an information table of a PMT of a carrier frequency. When there are subprograms concerning the main program, information of the PMT of the subprogram numbers is described in the PMT. Thus, the main channel which can be set from the PAT and the subchannels which are set into the main program and are set from the PMT of the main program can be set. The subchannel can be set after it was set into the main channel and cannot be directly set. In the other cases, the subchannels are channels similar to the main channel and the scrambling and charging can be independently set from the main channel.
