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： In accordance with an embodiment, a best-effort service is divided into packets for best-effort digital broadcast transmission. The packets are encapsulated with an encapsulation protocol that uses a packet order defining field. The encapsulated packets are inserted into an unused portion of a slot of a digital broadcast transmission frame. Then, the encapsulated packets are repeatedly inserted into the unused portion of the slot of the digital broadcast transmission frame in a packet-carousel fashion. And the transmission frame is digitally broadcast. In accordance with an embodiment, a digital broadcast transmission is received. Encapsulated packets that have been repeatedly broadcast in a packet-carousel fashion are accessed from a best-effort portion of a digital broadcast transmission frame slot. And a best-effort service is composed from the encapsulated packets by combining the encapsulated packets in an order based on a packet order defining field of the encapsulated packets.

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。
