KR970014200A - Program start time display device of television receiver - Google Patents

Abstract

The present invention relates to a program starting point display apparatus of a television receiver that can display a program start state of each broadcasting station. The present invention is based on KVPS (Korea Video Program Service) currently in execution plan at each broadcasting station. . That is, according to the KVPS, a specific frequency signal is transmitted at the start of a broadcast program. In the present invention, each broadcast channel for controlling a tuner is sequentially internationalized, and the frequency signal is detected through a predetermined frequency detecting means. When the frequency signal is detected, the audio signal of the corresponding broadcast channel is displayed through the speaker so that the viewer can easily recognize the broadcast channel on which the program is started.
