Abstract

The present invention discloses a double / wide television receiver integrated with a double deck video tape recorder having a telephone reception function and a receiving method thereof. The apparatus and method input a telephone ring signal to detect only an external telephone ring signal, According to the ring control signal, the telephone on-screen display signal is shown to the user on the screen, and the voice of the caller is provided through the speaker according to whether the user receives the call. By removing and detecting only an externally provided telephone ring signal, there is an effect of eliminating an error that may occur due to the telephone sound by the television set itself.
