Abstract

PURPOSE:To efficiently use a memory area by allocating more memory areas to a program with high rating by counting the number of times of view at every selected channel and program number, and storing only the teletext data of the program number with high rating at every television broadcast channel. CONSTITUTION:When teletext is viewed, the number of times of view at every television broadcast channel and program to be viewed is counted, and a count value is stored in a nonvolatile RAM 8d. When received teletext data is stored, the program number included in the data is confirmed, and when the rating at every channel computed from the number of times of view of the program in a channel being received stored in the nonvolatile RAM 8d exceeds a prescribed value, the data is stored in a RAM 8c in sequence of reception. In such a way, more memory areas are allocated to the program with high rating, which enables the memory area to be efficiently used.
