Abstract: Systems and methods are provided that combine Open Mobile Alliance Mobile Broadcast Services (OMA BCAST) with different bearers, such as China Multimedia Mobile Broadcasting (CMMB) by associating service-related identifiers within an OMA BCAST Electronic Service Guide (ESG) with CMMB bearer-specific parameters. Furthermore, associating IP source and/or destination address pairs of a service with the location of the service within the CMMB bearer can be achieved and used with unicast, multicast, and broadcast environments. Further still, systems and methods are provided that allow for ESG bootstrapping, where a desired electronic service guide can be discovered by bootstrapping, e.g., OMA BCAST ESG.

Abstract: 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.

Apparatuses may perform and methods may include: performing a handover using the extracted other multiplex information and continuing to receive services after the performance of the handover using information included in the other multiplex information.

Abstract: Methods and systems for addressing fringe areas within a broadcast network are described. At least one broadcast stream may be transmitted at a broadcast network A determination may be made as to whether a fringe area exists in the broadcast network. Information of the fringe area may be provided to a receiver in at least one signaling section associated to the at least one broadcast stream. A fringe area may occur within a single transmitter coverage area or cell of the broadcast network or over a plurality of different transmitter coverage areas or cells within the broadcast network. The fringe areas may be represented by one or more generally elliptically shaped regions.

Abstract: Broadcast services and other transmissions may conform to multiple types of protocols. Accordingly, a broadcast system may tunnel broadcasts or transmissions of a first protocol in a transport stream conforming to a second protocol. Each of the tunneled streams may be multicast together and may correspond to a separate and different physical layer pipe. The types of protocols and physical layer pipes carried in the transport stream may be defined in a pre-signaling section and/or post-signaling section of the transport stream. Common physical layer pipes may be generated and included in the transport stream to carry information and data common to multiple broadcast services or transmissions such as program specific information or service information.

Abstract: Data for a second Multi-Protocol Encapsulation-Forward Error Correcting (MPE-FEC) data frame is received while application data from a first MPE-FEC frame is undergoing error correction. The incoming data is buffered in a supplemental buffer having a size smaller than that needed for an entire MPE-FEC frame. As the supplemental buffer is filled, additional data from the second frame is stored in a buffer previously used to store error correction data for the first MPE-FEC frame. When corrected application data from the first MPE-FEC frame is transferred from an application data buffer used to hold application data undergoing correction, the second MPE-FEC frame data is transferred from the supplemental and error correction data buffers to the application data buffer. Additional data for the second frame is then placed directly into the application and error correction data buffers.

Abstract: Systems and methods applicable, for instance, in wireless communications. For example, a mobile node and/or other computer receiving a time slice burst of an elementary stream may act to obtain a delta-t time value specifying time to elapse until a subsequent burst, and/or may act to obtain information corresponding to burst length. As another example, the mobile node and/or other computer may set in view of the delta-t time value an alarm elapsed time value for activating reception circuitry. As yet another example, the mobile node and/or other computer may set in view of the information corresponding to burst length an alarm elapsed time value for deactivating reception circuitry.
