    摘要： Aspects of the invention are directed to service and channel discovery in a digital broadcast network. A pilot synchronization symbol, which has known characteristics, is included as a first symbol of digital broadcast frames. The pilot symbol, which can be decoded without having to resort to trial and error methods, contains parameters for the rest of the signal. So, the rest of the signal can be decoded without trial and error methods after the pilot symbol (and any additional synchronization symbols) is decoded. Channels containing digital video broadcast services can be efficiently detected using the known part of the signal. If the fixed known part is not found from the examined signal, then the signal will be considered a non-digital-video-broadcast signal or an empty channel, and the receiver can promptly proceed to a next channel/frequency. In this way, detecting non-digital-video-broadcast and empty channels becomes relatively fast.

    摘要： The invention is directed to efficient transfer of low bit rate services in a communication system. A synchronization symbol which has known characteristics may be included as a first symbol of digital broadcast frames. The synchronization symbol, which can be decoded without having to resort to trial and error methods, contains parameters for the rest of the signal. Low bit rate services are allocated to time slots following the pilot symbol used for synchronization allowing for fast access times with maximum power saving capabilities. A user terminal wakes up just before the synchronization symbol and received the data allocated for the low bit rate services. The user terminal may power off for the remaining time slots which are allocated for higher bit services to conserve power.

    摘要： 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.
