Abstract
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.
