摘要： Aspects of the invention are directed to physical layer and data link layer signaling in digital video broadcast preamble symbols. Embodiments are directed to distributing physical layer pre-signalling data among preamble symbols. If physical layer data is larger than a predetermined number of preamble symbols, then excess physical layer data is written to data symbols immediately following the preamble symbols in top-down order symbol by symbol or the predetermined number of preamble symbols is increased. If physical layer data is not larger than the predetermined number of preamble symbols such that there is excess preamble symbol space, physical layer pipe 0 data comprising link layer signaling and notification data is carried in the excess preamble symbols or the excess preamble symbols are left empty. Different permutation rules may be used to frequency interleave odd-numbered versus even-numbered orthogonal frequency division multiplexing symbols.

摘要： A system and method for improving signaling channel robustness. Additional error correction is provided for (L1) dynamic signaling that is carried in P2 symbols in such way that high time diversity can be provided. In other embodiments, transmitted services are scheduled such that services will rotate or “move” between frames, thereby ensuring that a first slot for a service is not always transmitted in the same frequency.

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： A receiver is arranged to start receiving a data frame 80 including application data followed by parity data. An erasure information table is generated, and includes one element for each element of a data frame 80. If there are no errors in the application data, the receiver is powered-down to sleep without receiving the parity data, and the application data is used without correction being needed. If the number of errors in the application and parity data exceeds the MPE-FEC correction capability, the receiver is powered-down to sleep without further parity data being received and the data is not decoded. If the number of errors is smaller than the MPE-FEC correction capability, the receiver is powered-down to sleep when sufficient parity data is received to correct errors in the application and parity data. This can save power in the receiver. In another embodiment, the erasure information table includes one element for each column of a data frame.
摘要翻译：接收器被安排为开始接收包括紧随奇偶校验数据的应用数据的数据帧80。生成擦除信息表，并且包括用于数据帧80的每个元素的一个元素。如果应用数据中没有错误，则接收机被断电以睡眠而不接收奇偶校验数据，并且使用应用数据不需要校正。如果应用程序和奇偶校验数据中的错误数量超过了MPE-FEC校正能力，则接收机掉电睡眠，无需接收到另外的奇偶校验数据，并且数据不被解码。如果错误数量小于MPE-FEC校正能力，则接收器在接收到足够的奇偶校验数据以校正应用中的错误和奇偶校验数据时，将其关闭以进行休眠。这可以节省接收机的电量。在另一个实施例中，擦除信息表包括用于数据帧的每列的一个元素。

摘要： Aspects of the invention are directed to signalling extension frames in a telecommunication system. Extension-frame-signalling data may signal whether one or more extension parts are present in one or more gaps in time between data frames, when the one or more extension parts occur, and one or more durations for the one or more extension parts. The one or more extension parts may occur on the same radio frequencies as the data frames. The extension-frame-signalling data may signal when the one or more extension parts occur by signalling after which of one or more data frames in a super frame the extension parts occur. The one or more durations for the extension parts may be expressed in units of time.
摘要翻译：本发明的方面涉及电信系统中的信令扩展帧。扩展帧信令数据可以指示在一个或多个扩展部分出现时，数据帧之间的一个或多个时间间隔中存在一个或多个扩展部分是否存在一个或多个扩展部分，以及一个或多个扩展部分的一个或多个持续时间。一个或多个扩展部分可以在与数据帧相同的无线电频率上发生。扩展帧信令数据可以在通过信令发生一个或多个扩展部分时出现信号，在扩展部分发生超帧中的一个或多个数据帧之后。扩展部分的一个或多个持续时间可以以时间为单位表示。

摘要： Apparatus and methods are provided for adaptively determining a handover measurement interval. Power savings are achieved when a mobile terminal in a digital broadcast broadband network does not constantly attempt to measure the signal strength of nearby cells. By determining cell parameters, such as size and carrier frequency, and also determining dynamic information, such as signal strength and mobile speed over time, the time until the next handover measurement is adjusted up or down. When a mobile terminal is moving towards a transmitter in a cell, the handover measurement interval may be lengthened, and when a mobile terminal is moving away from a transmitter, the interval may be shortened.
