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.
摘要翻译：可以使用逻辑层管线（LLP）将广播网络中的服务和服务组件映射到不同的物理层传输信道（PLP）。使用LLP允许将单个服务的不同服务组件映射到物理层传输信道（PLP）。因此，服务组件可以在不同的服务之间共享。附加地或替代地，可以将不同的功能（例如，不同的错误检测或校正协议）应用于服务的每个服务组件。接收机可以基于LLP标识符识别服务，服务组件和对应的PLP。然后，接收机可以通过所识别的PLP访问和接收所需的服务和服务组件。

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： 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： A system and method for dynamically dividing the capacity of a fixed time division multiplexing (TDM) frame between physical channels for data transmission. According to various embodiments, a time frequency frame is divided into a plurality of subframes, and each of the plurality of subframes are divided into a plurality of corresponding slots. The plurality of slots are then selectively time shifted such that a defined time shift exists between corresponding slots in each subframe within the time frequency frame. For any slots or slot portions which have been selectively shifted beyond the end of the time frequency frame, such slots or slot portions are cyclically shifted to the beginning of the frame. Service data is then written into the slots of the time frequency frame, and the frame containing the service data can then be transmitted. Initialization and service access processes for a receiver are also provided.
