    • A transport demultiplexor system and queue remultiplexing methodology includes: a packet buffer for receiving data packets belonging to an input transport stream, each packet having a corresponding identifier identifying a program to which the packet belongs; a data unloader device for pulling successive packets from the packet buffer for storage in a memory storage device, and writing the pulled packets into contiguous address locations in the memory; and, a remultiplexor mechanism for generating an address offset associated with a next data packet pulled from the packet buffer to be stored in memory and writing it to a new memory location that is offset from a memory location assigned to a previously pulled packet, the offset defining a memory gap in the memory storage device capable of being filled new data content.
    • 传输解复用器系统和队列重新复用方法包括:用于接收属于输入传输流的数据分组的分组缓冲器,每个分组具有标识分组所属程序的对应标识符; 数据卸载装置,用于从分组缓冲器中拉取连续的分组以存储在存储器存储装置中,并将所拉出的分组写入存储器中的连续的地址位置; 以及再生多路复用机制,用于产生与从分组缓冲器拉出的下一个数据分组相关联的地址偏移量以存储在存储器中并将其写入与分配给先前拉出的分组的存储器位置偏移的新的存储器位置,偏移量 定义能够填充新数据内容的存储器存储设备中的存储器间隙。

    • Techniques are provided for re-mapping and interleaving transport packets of multiple transport streams for processing by a single transport demultiplexor. At least one PID re-map table is employed having re-map values indexed by n possible PID values of transport packets associated with at one transport stream of the multiple transport streams. The n possible PID values is less than or equal to the number of PID values which can be handled by the single transport demultiplexor, and is less than all possible PID values of transport packets within the multiple transport streams. The PID values within at least one transport stream are compared with the n possible PID values of the PID re-map table, and when a match is found, the table is indexed using the matching entry and a re-map value is generated therefrom. The re-map value replaces the original PID value within the transport packet.
    • 提供了用于重新映射和交织多个传输流的传输分组以供单个传输解复用器处理的技术。 使用至少一个PID重映射表,其具有由与多个传输流的一个传输流相关联的传输分组的n个可能PID值索引的重新映射值。 n个可能的PID值小于或等于单个传输解复用器可以处理的PID值的数量,并且小于多个传输流中的传输分组的所有可能的PID值。 将至少一个传输流中的PID值与PID重映射表的n个可能PID值进行比较,并且当找到匹配时,使用匹配条目对表进行索引,并从其生成重映射值。 重新映射值替换传输数据包中的原始PID值。
