DIGITAL BROADCAST SIGNAL RECEIVING SET AND BROADCAST SIGNAL RECEIVING APPARATUS

PROBLEM TO BE SOLVED: To solve a problem where aspect change of images associated with a channel change is not made quickly. SOLUTION: A TV 110 extracts aspect ratio information about each program of each channel which is overlapped on digital television broadcast signals from digital television broadcast signals periodically, and records the same to a recording medium 50, and when the instruction of change of the channel is input from the outside on the other hand, immediately reads out the aspect ratio information corresponding to the program of the channel of the change destination by the instruction concerned from the recording medium 50, and notifies the same to a microcomputer 90 which controls a scaler 80. Consequently, in comparison with the prior art, it is possible to greatly shorten the time required to notify the aspect ratio information to the side of the scaler 80. COPYRIGHT: (C)2008,JPO&INPIT
