Abstract

See full text

A system and method for transmitting files from a sender to a receiver in a television distribution system, for example, a cable television distribution network, is provided. The files are transmitted without the need for transmitting a directory over an out of band communications link. In an exemplary embodiment, a filename corresponding to a file to be transmitted is provided to a transform. The transform calculates a PID based on the filename. The calculated PID is incorporated into the MPEG2 data stream carrying the corresponding file contents. When an application program running in the receiver requests a file, the filename of the requested file is provided to a transform operating in the receiver. The transmitter and receiver transforms are identical. The transform provides a corresponding PID at its output. The PID is used to tune a PID filter on the receiver end such that the requested file is selected from the incoming MPEG bit stream for processing by the processor.
