Embodiment Construction

[0060] 1. Concept of the present invention (applicable to the case of broadcasting system)

[0061] FIG. 1 is a conceptual diagram of an information communication system according to an embodiment of the present invention. The broadcasting device 2 broadcasts to many receiving devices 6 together through the broadcasting path. In addition, the operating state control data is transmitted from the broadcasting device 2 to the receiving device 6 through the communication path. When the receiving device 6 recovers after receiving the broadcast signal, it changes its operating state based on the operating state control data. In this way, the advantages of simultaneous broadcasting can be fully utilized, and at the same time, the operation of each receiving device 6 can be individually controlled by using the operation state control data.

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.

Description

[0001] The entire disclosure of Japanese Patent Application No. 2000 247326 (filed on August 17, 2000), including the specification, scope of claims, drawings, and abstract, is incorporated into this application. (1) Technical field [0002] The present invention relates to a technique for controlling a receiving device from a transmitting device such as a broadcasting device through a communication path. (2) Background technology [0003] The broadcast system has the advantage of being able to provide programs together at low cost to many receiving apparatuses. However, conversely, since transmission is basically performed together, it is not easy to control the operation of each receiving device from the transmitting device side. [0004] In addition, not limited to the broadcasting system, when information is transmitted from the transmitting side to the receiving side, an operator on the receiving side may be required to perform an operation related to the information. ...
