Abstract:
A packet-transmitting system having at least one control-signal transmission channel and a plurality of data-signal transmission channels, said system comprising:a transmitter apparatus including: packet-allocating section for receiving a stream of packets and allocating groups of packets to the data-signal transmission channels: time-dividing/multiplexing section for receiving packet-group data representing the packets allocated to each data-signal transmission channel by the section and for time-dividing and multiplexing the packet-allocating packet-group data to the control-signal transmission channel; and multiplexer/adder section for multiplexing a signal in the control-signal transmission channel and signals in the data-signal transmission channels in parallel, thereby to generate signals to be transmitted; and a receiver apparatus including: signal-distributing section for distributing the signals to a plurality of channels; group-data acquiring section for reproducing the signal in the data-signal transmission channel from a signal distributed to any channel by the signal-distributing section, thereby to acquire group data about the data-signal transmission channels; channel-selecting section for selecting a data-signal transmission channel to which a packet group designated is allocated, in accordance with the group data acquired by the group-data acquiring section; and selected-channel reproducing section for reproducing a signal in the data-signal transmission channel selected by the channel-selecting section, from the signals in some of the transmission channels to which the signal-distributing section has distributed the signals and for extracting only the packets of the group designated, said signals in some transmission channels not having been used in the group-data acquiring section.
