发明名称 Interactive access to supplementary material related to a program being broadcast
摘要 <p>A method and apparatus for interacting with a broadcast program that is being performed, enabling access to supplementary materials related to the program from a broadcast signal that is a combination of a programming signal and a supplementary materials signal. The broadcast output signal is received at a location of an audience. The programming signal of the received output signal is performed for the audience, with reproduction equipment. A signal related to the supplementary material signal is extracted from the received broadcast signal.
