Abstract

PROBLEM TO BE SOLVED: To solve the problem of there being the any possibility that program information at that day or in the future to be frequently referred to exceeds the capacity of a non-volatile storage medium, such as a flash memory since the transmission quantity of the program information is increased due to the increase of the total number of services in a BS/CS digital broadcasting receiver according as CS digital broadcasting starts, and the problem of there being a possibility that a broadcasting network, incapable of storing sufficient program information, being generated due to the generation of bias in the storage of the program information between a plurality of broadcasting networks. SOLUTION: Received program information is temporarily stored in the buffer of a volatile storage medium, and the program information in the relatively close future among the program information stored in the buffer is stored in a non-volatile storage medium, and the maximum storage capacity is decided in each broadcasting network, so that the bias of the storage between a plurality of broadcasting networks can be suppressed.

Further, because of the multi-broadcast network configuration, it is conceivable that there will be a bias in the progress of the accumulation of program information among the broadcasting networks, and there will be broadcasting networks in which sufficient program information cannot be accumulated. The program information that has not been stored is displayed waiting for reception when you refer to the program table.
The information is displayed later than the information stored in the non-volatile storage medium.
