Content delivery and management in networked MPEG-4 system

Networking of MPEG-4 content is the topic of standardization efforts in the ISO MPEG and IETF. DMIF (Delivery Multimedia Integration Framework) was developed in the ISO MPEG as a generic networking platform for MPEG-4 content. In this paper we are describing the implementation of a MPEG-4 client-server architecture, uses DMIF with Internet RTSP (Real Time Streaming Protocol) for signaling. Mapping of DMIF functionalities onto RTSP messages is shown. The implemented system runs on PC platform and its operation is explained in details.
