Abstract
A service channel is provided for concurrent communication with an amplitude modulated compatible digital broadcast signal. A transmitter receives input program information and input data service and combines the program information and data service to produce composite data. The transmitter generates an over-the-air signal waveform using the composite data. This signal is an amplitude modulated compatible digital broadcast signal. At least one receiver is used in the system to detect the over-the-air signal waveform produced by the transmitter. The receiver parses the composite data into program information and data service. The parsing of this composite data is achieved by using header information provided on each of the input program information and input data service.
