ABSTRACT:
A method and apparatus for filling audio blanks in a message received by a receiver resulting from switching the receiver between a plurality of input channels each having a different message for selecting the channel of highest priority is disclosed. A recording and playback device is connected between the receiver and an output channel for recording a given time segment portion of a first message. The receiver is switched to a second channel for a period of time equal to the given time segment for receiving a second message and for determining which channel has a higher priority. The recorded portion of the first message is delivered to the output channel simultaneously with the switching of the receiver to the second channel to repeat the first message portion at the output channel, thereby to fill in the audio blank resulting from switching the receiver between the input channels.
