Stream Selection Policies for Transcoding Multimedia Presentations Composed of Multiple Streams to Play on Mobile Terminals

This paper proposes various policies and experiment results to select streams in a presentation to be transcoded for mobile terminals after distinguishing the characteristics of streams in the presentation. This applies to a presentation composed of various data streams on a PC server. The rationale of the research is that stream selection policies for transcoding enhance the speed of presentation in mobile terminals considerably faster than in the case when every stream has to be transcoded. Thus, the thesis suggests a stream selection policy for transcoding based on EPOB (End Point of Over Bandwidth) and aims to lower the required bandwidth of the presentation to the network bandwidth as well as to minimize initial delay time for the presentation to be played on mobile terminals.
