1. A method for processing a digital signal in a receiver, comprising the steps of: receiving a digital signal containing an availability of a service, a deterministic mapping corresponding to the service, and a service content, wherein the service content is recognized at one or more known symbol locations within a physical layer based on the deterministic mapping, wherein the deterministic mapping further corresponds at least to a mapping of an interleaver; and performing an operation on the service content in accordance with the deterministic mapping.
