    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： 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 is provided for ensuring that time for tuning to another RF channel between two TF frames in TF slicing exists while reception with a single hopping-tuner is enabled, and reception for terminals can be guaranteed when transmitting and receiving common services. An additional time for tuning is introduced for TF-sliced services, where the time for tuning can be inserted either before of after the P1 & P2 symbols, and the symbols allocated for the tuning time can also be used for transmission of low-bit rate services. Alternatively, additional padding bits and a guard period can be added in the event that slots or slot fragments exceed a cyclic transfer border upon time shifting. Alternatively still, the tuning time is represented by a complete TF frame, where the complete TF frame carries services other than those in the first TF frame, so that a service is transmitted in every second TF frame and a receiver can perform tuning during the TF frames which do not carry the service.

    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。
