Abstract

A DIGITAL AUDIO BROADCAST RECEIVING APPARATUS ( 1) THAT MINIMIZES A FREQUENCY AT WHICH THE USER SWITCHES BETWEEN NICAM AUDIO AND ANALOG AUDIO. WHEN A RESERVE AUDIO SWITCHING FLAG (C4) IS "H" IT INDICATES THAT ANALOG AUDIO AND NICAM AUDIO REPRESENT THE SAME PROGRAM, IN WHICH NICAM AUDIO, WHICH PROVIDES BETTER SOUND QUALITY, IS AUTOMATICALLY SELECTED. IF A BROADCAST RECEIVING CONDITION DETERIORATES, ANALOG AUDIO IS AUTOMATICALLY SELECTED. CONVERSELY, WHEN THE FLAG (C4) IS "L", IT INDICATES THAT NICAM AUDIO AND ANALOG AUDIO REPRESENT TWO DIFFERENT PROGRAMS. IN THIS CASE, ANALOG AUDIO THAT IS IN SYNCHRONIZATION WITH VIDEO IS AUTOMATICALLY SELECTED. AT THIS MOMENT, IT IS POSSIBLE THAT THE USER INTENTIONALLY SELECTS NICAM AUDIO, WHICH IS NOT RELATED TO VIDEO, SO THAT NICAM AUDIO IS NOT SWITCHED TO ANALOG AUDIO EVEN IF NICAM AUDIO HAS SOME NOISE. AN AUDIO SWITCHING POINT IS SHIFTED BY CHANGING A THRESHOLD FOR DETERMINING PCM DATA ERROR RATE OR BY CHANGING A SAMPLING TIME.(FIG 1)
