A computer-based media data processor for controlling transmission of digitized media data in a packet switching network. When the processor receives a request from a network client node for presentation of specified media data stream presentation unit sequences the processor in response retrieves media data from a corresponding media access location, determines the media data type of each presentation unit in the retrieved media data, and designates each retrieved presentation unit to a specific media data presentation unit sequence based on the media data type determination for that presentation unit. The processor then assembles a sequence of presentation descriptors for each of the specific presentation unit sequences, all presentation descriptors in an assembled sequence being of a common media data type, and then assembles transmission presentation unit packets each composed of at least a portion of a presentation descriptor and its media data, all presentation descriptors and media data in an assembled packet being of a common media data type. The assembled packets are then released for transmission via the network to the client processing node requesting presentation of the specified presentation unit sequences.
