COMMUNICATION SYSTEM, COMMUNICATION APPARATUS WHICH CAN BE CONNECTED TO COMMUNICATION SYSTEM, CONTROL METHOD FOR CONTROL SYSTEM, AND CONTROL METHOD FOR COMMUNICATION APPARATUS WHICH CAN BE CONNECTED TO COMMUNICATION SYSTEM

摘要

Signals are evenly distributed and transmitted using a plurality of channels. Multicast and broadcast communications are efficiently made. Signals from each sub transmission paths are distributed onto a plurality of channels to send them via these channels. Furthermore, signals are inserted into the channels by finding empty packets from the channels, thus allowing input of signals to the channels that transfer various kinds of signals. Upon multicast or broadcast communications, an input signal is copied in correspondence with a plurality of channels.
