摘要： Embodiments are directed to transmitting L1 pre-signaling information with predetermined modulation and code rate such that L1 pre-signaling information can be received without preliminary knowledge on the network. L1 pre-signaling information makes it possible to receive the L1 signaling information, data link layer information, and notification data that may have configurable code rates and modulation. Therefore, L1 pre-signaling information can be thought of as signaling metadata (i.e., information about other signaling information). L1 signaling is divided into pre-signaling and signaling parts. The pre-signaling part includes parameters used for receiving the L1 signaling information. L1 pre-signaling signaling enables the receiver to receive the signaling itself (L1 signaling and data link layer information) by informing the receiver about the type of modulation, coding, and the like, used to transmit the L1 signaling, data link layer, and notification information.

摘要： Aspects of the invention are directed to service discovery in a digital broadcast network. A service discovery descriptor, which may be electronic service guide-provider and cell specific, provides mapping between a service identifier, a logical channel identifier, and a physical channel, which may be characterized by a frame identifier and a slot identifier, that is, each physical channel may have one or more slots within one or more frames. A neighboring service discovery descriptor provides mapping for the service available within neighboring cells. Aspects of the invention are directed to an encapsulation protocol that encapsulates variable length data, including, but not limited to, the service discovery descriptor and the neighboring service discovery descriptor, into fixed length data stream packets.

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.

摘要： Embodiments are directed to transmitting receiver-capacity-signalling data that specifies a plurality of receiver capacities to be used for receiving a service. The signalled receiver capacities may include: a type of time interleaver being used and a minimum burst interval between two consequent bursts. The signaled receiver capacities may also specify: how often a physical layer pipe appears in frames, and/or a number of a frame in which a physical layer pipe appears for a first time during a super frame. Embodiments are directed to receiving the receiver-capacity-signalling data and if, based on the received receiver-capacity-signalling data, receiver capacity is sufficient for one or more selected services, performing service discovery and decoding the one or more services. Otherwise, decoding the one or more services may not be performed.

摘要： In accordance with an embodiment, a best-effort service is divided into packets for best-effort digital broadcast transmission. The packets are encapsulated with an encapsulation protocol that uses a packet order defining field. The encapsulated packets are inserted into an unused portion of a slot of a digital broadcast transmission frame. Then, the encapsulated packets are repeatedly inserted into the unused portion of the slot of the digital broadcast transmission frame in a packet-carousel fashion. And the transmission frame is digitally broadcast. In accordance with an embodiment, a digital broadcast transmission is received. Encapsulated packets that have been repeatedly broadcast in a packet-carousel fashion are accessed from a best-effort portion of a digital broadcast transmission frame slot. And a best-effort service is composed from the encapsulated packets by combining the encapsulated packets in an order based on a packet order defining field of the encapsulated packets.
