Information communication system
First Claim
1. An information communication system comprising:
- a broadcasting device transmitting a broadcasting signal; and
a receiving device receiving the broadcasting signal from the broadcasting device via a broadcasting path, wherein the broadcasting device comprises;
a broadcasting transmission part for transmitting the broadcasting signal simultaneous to a plurality of receiving devices via the broadcasting path; and
a control data transmission part for transmitting operation control data controlling an operation mode of the receiving device through a communications path which is different from the broadcasting path; and
wherein the receiving device each comprises;
a broadcasting receiving part for receiving the broadcasting signal via the transmission path;
a control data receiving part for receiving the operation control data from the control data transmission part through the communications path; and
a control part performing a control process including a decoding process in which the broadcasting signal received by the broadcasting receiving part are decoded and the decoded signals are outputted to a user, the control part changing the control in accordance with the operation control data received by the control data receiving part.

Abstract
The present invention provides a system capable of individually controlling each of receiving devices while making full use of the advantages of broadcasting. Simultaneous transmission is carried out from a broadcasting device 2 to a plurality of receiving devices 6 via a broadcasting path. Further, the broadcasting device 2 sends operation control data to the receiving device 6 through a communication path. The receiving device 6 changes its operation in accordance with the operation control data when received broadcasting is decoded. In this way, each of the receiver devices 6 can be controlled individually using the operation control data while making full use of the advantages of broadcasting.
