Abstract
To provide an information repeater system capable of selecting a desired broadcasting program with a simple construction, in the information repeater system for receiving a broadcasting wave formed by multiplexing plural broadcastings and distributing it to the corresponding channel of a specified broadcasting system. Data streams D25A, D25B, . . . D25N relayed by specified transponders are extracted from the broadcasting wave S1. Arbitrary packets D32A, D32B, . . . D32N are specified and extracted from the above data streams. Thus extracted packets are transmitted to the specified channel of the specified broadcasting system. Thereby, the desired channel can be transmitted to the desired channel of the specified broadcasting system from among the plural broadcastings multiplexed in the broadcasting wave.
Claims19
An information repeater system for receiving N (N is an integer greater than 1) broadcast waves transmitted from plural transponders each broadcast wave being formed of multiplexed broadcast channels with each channel comprising transport stream packets;
- said system comprising:
- receiving means for receiving said N broadcast waves and for extracting said broadcast channels therefrom;
- packet extracting means for extracting selected packets from the transport stream packets in each channel;
- remultiplexing means for remultiplexing combinations of said extracted packets from different transponders to form M remultiplexed channels of transport stream packets, where M is an integer greater than 1;
- and
- transmission means for transmitting respective ones of said M remultiplexed channels to predetermined ones of M output channels.
A method for relaying information from N received broadcast waves, where N is an integer greater than 1, and the N broadcast waves are transmitted from plural transponders, with each broadcast wave being formed of multiplexed broadcast channels, with each channel comprising transport stream packets, said method comprising the steps of:
- receiving said N broadcast waves and extracting said broadcast channels therefrom;
- extracting selected packets from the transport stream packets in each channel;
- remultiplexing combinations of said extracted packets from different transponders to form M remultiplexed channels of transport stream packets, where M is an integer greater than 1;
- and
- transmitting respective ones of said M remultiplexed channels to predetermined ones of M output channels.
