AB  - This paper introduces two signaling techniques that may be useful in broadcast applications for combining supplemental data with program material. Such data may be used to monitor audience participation, advertising placement or to convey additional program information (including lyrics and URLs). The first technique involves replacing unused bits, or fill bits, in fixed data-rate compression systems with information-carrying data in a way that does not affect the quality of the program material and does not necessitate modification of encoders or decoders. A second technique involves modulating the bandwidth of a signal and adding perceptually shaped noise to create an inaudible, constant-rate supplemental signal. Both techniques may be integrated with the Dolby Digital perceptual coding system.
