    Abstract: A plurality of digital services (V'1-V'N' and A'1-A'N') are carried in a multiplex data stream (162) to a plurality of remote locations. The multiplex data stream (162) comprises a continuous sequence of frames (156). Each frame (156) comprises two consecutive fields, and each field comprises a plurality of lines. A first group of the lines in each field defines a transport layer region of that field, and a second group of the lines defines a service data region. Portions of the service data region of each field are allocated to respective ones of the video services in proportion to respective data rates of each service. A multiplex control packet is generated (104) for each field that specifies, for each service, which portion of the service data region is allocated to that service. A multiplex map (104) is transmitted with each field, and therefore, the number and location of packets may be dynamically adjusted on a per field basis.

    Abstract translation: 多个数字服务（V'1-V'N'和A'1-A'N'）在多路复用数据流（162）中被携带到多个远程位置。 复用数据流（162）包括连续的帧序列（156）。 每个帧（156）包括两个连续的场，并且每个场包括多个行。 每个字段中的第一组行定义该字段的传输层区域，并且第二组行定义服务数据区域。 每个视频服务的服务数据区域的部分按照每个服务的相应数据速率的比例分配给视频服务的相应的一部分。 为每个字段生成多路复用控制分组（104），对于每个服务，为服务数据区域的哪个部分分配给该服务。 与每个字段一起发送复用映射（104），因此可以在每个字段的基础上动态地调整数据包的数量和位置。

    Abstract: Video and audio data are prepared in the form of a packetized elementary stream having a header, a presentation time stamp, and the video itself. The packetized elementary stream is allocated into the payload section of one or more transport packets. Transport packets are usually 188 bits in length herein and include a synchronization block and prefix data followed by the payload data. The multiplex/encryptor (64) combines individual transport packets (62) into a frame of data (60).

    Abstract: The Logical Channel Table (LCT), utilizing simple conventional channels or Composite Channels, provides mapping between a Logical Channel Number (LCN) representing a service and the transport stream (TSID) / program number (PN) on which the service can be found. The LCT entry contains a Composite Channel Indicator (CCI), which when set to '1', indicates that the selected channel is a composite channel thereby indicating the home channel of the Composite Channel. The LCT provides the Composite Channel Table (CCT) to the decoder (10) so that the tuner (12) can be returned to the actual program designated in the CCT for current viewing. Each entry in the CCT associates a Composite Channel Number (CCN) with a LCN and represents the "present" definition for the composite channel. As time progresses, the CCN is used as a "pointer" to the LCN which is the currently active service for the composite channel. These tables work with conventional MPEG-2 service definitions to decode multi-service transport streams.

    Abstract translation: 使用简单的常规信道或复合信道的逻辑信道表（LCT）提供了表示服务的逻辑信道号（LCN）和可以在其上找到服务的传输流（TSID）/节目号（PN）之间的映射。 LCT条目包含复合信道指示符（CCI），当被设置为“1”时，指示所选择的信道是复合信道，从而指示复合信道的归属信道。 LCT向解码器（10）提供复合频道表（CCT），使得调谐器（12）可以返回到CCT中指定的实际程序，以便当前观看。 CCT中的每个条目将复合通道号（CCN）与LCN相关联，并表示复合通道的“当前”定义。 随着时间的推移，CCN被用作指向LCN的“指针”，LCN是组合通道的当前活动服务。 这些表适用于传统的MPEG-2服务定义来解码多业务传输流。

    Abstract: A packet of data, which contains a timestamp value and which is to be transmitted through an ATM network, is encapsulated in a convergence sublayer protocol data unit (92) having a header (96) and a payload (94). The CS-PDU is then segmented into successive segments (106, 108, 110 and 112) with one segment (106) containing the CS-PDU header (96). The segments (106, 108, 110 and 112) are inserted in respective ATM cells (114, 116, 118 and 120) and transmitted through the ATM network. At each node in the ATM network, any variable delays imposed on the cell (114) that contains CS-PDU header (96) are added to a time reference correction field (100) in the CS-PDU header (96). At a destination node, the accumulated delay value in the TRC field (100) of the CS-PDU header (96) can be added to the timestamp value of the packet to compensate for the variable delays imposed by the ATM network.

    Abstract translation: 包含时间戳值并且要通过ATM网络发送的数据包被封装在具有报头（96）和有效载荷（94）的汇聚子层协议数据单元（92）中。 然后，CS-PDU被分段成具有包含CS-PDU报头（96）的一个段（106）的连续段（106,108,110和112）。 这些段（106,108,110和112）被插入相应的ATM信元（114,116,118和120）中并通过ATM网络传输。 在ATM网络中的每个节点处，施加在包含CS-PDU报头（96）的小区（114）上的任何可变延迟都被添加到CS-PDU报头（96）中的时间基准校正字段（100）。 在目的地节点，CS-PDU头（96）的TRC字段（100）中的累积延迟值可以被添加到分组的时间戳值，以补偿由ATM网络施加的可变延迟。
