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.
摘要翻译：本发明涉及在通信系统中低比特率服务的有效传输。可以包括具有已知特征的同步符号作为数字广播帧的第一符号。可以解码而不必诉诸试验和误差方法的同步符号包含信号其余部分的参数。低比特率服务被分配到用于同步的导频符号之后的时隙，允许具有最大功率节省能力的快速接入时间。用户终端在同步符号之前醒来并接收分配给低比特率服务的数据。用户终端可以为分配给较高位服务的剩余时隙断电以节省功率。

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： 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.
摘要翻译：本发明的方面涉及数字广播网络中的服务发现。可以是电子服务指南提供者和小区特定的服务发现描述符提供服务标识符，逻辑信道标识符和物理信道之间的映射，其可以由帧标识符和时隙标识符来表征，每个物理信道可以在一个或多个帧内具有一个或多个时隙。相邻服务发现描述符为相邻小区中可用的服务提供映射。本发明的方面涉及将可变长度数据（包括但不限于服务发现描述符和相邻服务发现描述符）封装成固定长度数据流分组的封装协议。
