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.
摘要翻译：本发明的方面涉及数字广播网络中的服务和频道发现。具有已知特征的导频同步符号被包括为数字广播帧的第一符号。可以解码而无需诉诸试验和误差方法的导频符号包含信号其余部分的参数。因此，在对导频符号（和任何附加的同步符号）进行解码之后，可以对信号的其余部分进行解码而无需尝试和错误的方法。可以使用信号的已知部分有效地检测包含数字视频广播服务的信道。如果从被检查的信号中没有找到固定的已知部分，则该信号将被认为是非数字视频广播信号或空信道，并且接收机可以迅速进行到下一个信道/频率。以这种方式，检测非数字视频广播和空信道变得相对较快。

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： In accordance with at least one embodiment, fixed TDM slot/frame structure and statistical multiplexing are combined. A TDM slot, which is fixed (in size and position) is reserved for a variable bit rate service such that the bit rate of the TDM slot/channel is below the average rate of the service. Such a reserved TDM slot may be referred to as a service specific slot. Since the service specific slot is reserved with a bit rate below the average rate of the service, additional capacity is reserved from a rate matching slot, which may be common for multiple services. In this rate matching slot, the capacity may be shared between services according to any suitable strategy for allotting services to portions of the rate matching slot, including, but not limited to, a statistical multiplexing algorithm.
摘要翻译：根据至少一个实施例，组合固定TDM时隙/帧结构和统计复用。固定（尺寸和位置）的TDM时隙被保留用于可变比特率服务，使得TDM时隙/信道的比特率低于服务的平均速率。这样的保留TDM时隙可以被称为服务特定时隙。由于服务特定时隙是以低于服务平均速率的比特率保留的，所以从速率匹配时隙预留附加容量，这对于多个服务可能是共同的。在该速率匹配时隙中，可以根据用于将业务分配给速率匹配时隙的部分的任何合适的策略来在业务之间共享容量，包括但不限于统计复用算法。

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。
