Services and service components in a broadcast network may be mapped to disparate physical layer transmission channels (PLPs) using logical layer pipes (LLPs). The use of LLPs allows different service components of a single service to be mapped to physical layer transmission channels (PLPs). Accordingly, service components may be shared among different services. Additionally or alternatively, different functions (e.g., different error detection or correction protocols) may be applied to each service components of a service. A receiver may identify services, service components and corresponding PLPs based on LLP identifiers. The receiver may then access and receive desired services and service components through the identified PLPs.
