Summary:
This thesis presents a survey of multimedia networks and the techniques to improve the capacity of video on demand systems. A survey was conducted and comparative evaluation was done to determine the multimedia capabilities of various networks. Video on demand is an electronic video rental system in which clients request and play videos on-demand. Video on-demand system can be implemented over an existing cable TV network or an upgraded ADSL network. The two techniques used to improve the capacity of video on-demand systems are segmentation and multicasting. Segmentation consists of dividing the video into several fixed length segments, and then transmitting the segments at regular intervals instead of transmitting the video continuously. With multicasting, more than one user requesting the same video are served by a single video stream. Multicasting further assumes that each subscriber has a limited storage space, so same video segments can be multicast to subscribers simultaneously even if the requests for a video are not synchronous.
