Program information broadcasting system, broadcasting device, and receiving terminal unit

摘要

In a program information broadcasting system, it is aimed to minimize time for retrieval of program by viewers in operating an electronic program guide or time for waiting when applying for subscription. As a program information broadcasting system, program elements constituting a broadcasting program are divided into a plurality of items and are turned to data at a center, and a master data 21 of a program information to recognize the program is prepared. From the data constituting the master data, minimal necessary items for preparation of a program table are extracted, and a program basic information 22 is prepared. Said master data and said program basic information are transmitted simultaneously with the broadcasting, and said program basic information is received, reproduced and displayed before receiving of the master data at a receiving terminal unit 31 is completed. As a result, the program basic information having far less amount of data than the master data can be incorporated, and it is possible to minimize the time required for storage of the data in memory of the receiving terminal unit.
