Abstract
Systems, methods, apparatus and computer program products are provided for signaling to a receiver an availability of a service and a deterministic mapping of a service content corresponding to the service. A modulator receives a digital signal and generates a data frame from the digital signal, where the data frame is divided into segments, where at least one grouping of the segments contains the service content. The modulator modulates at least one grouping in accordance with the deterministic mapping. A receiving device receives a digital signal containing the availability of a service, the deterministic mapping corresponding to the service, and the service content, and performs an operation on the service content in accordance with the deterministic mapping.
