Abstract
A multi-bit program identification signal is transmitted in the audible band with a program signal, and a receiver detecting the program identification signal automatically sets a predetermined minimum volume for reproduction of the program information. The volume control circuitry at the receiver can be made responsive to any one of a plurality of different program identification signals.
Claims6
A broadcast wave receiver for receiving a program signal, said receiver having means for receiving a broadcast signal containing a program signal portion representing audio information and a program identification signal portion, and means for reproducing said audio information accordance with said program signal portion, said receiver including:
- an antenna;
- tuner means connected to said antenna;
- volume control means receiving the output from said tuner and responsive to a detection means for controlling the volume of reproduction of said audio information;
- said detection means receiving an output of said tuner means for detecting a predetermined program identification signal, said detection means comprising:
- means for detecting a selected one of a plurality of program identification signals, comprising:
- manually operated selection means for selecting that one of said program identification signals to be detected;
- sensing means for sensing said program identification signal portion;
- start code pattern generation means for selectively generating one of a plurality of different start code patterns;
- and
- comparison means for comparing said sensed program identification signal to the generated start code pattern and for providing an output signal to said volume control means when said compared patterns match.
