Abstract :
Streaming video to mobile devices like cellular phones is an important emerging application. However, mobile thin clients have limited capabilities and offer restricted interfaces to the end-user and the Telco infrastructure has significant technical barriers which limit the introduction of new protocols. This paper describes our design of an end-to-end interactive video service. We outline the technological and user-interaction challenges of providing one typical type of interactive controls-time-scale modification (TSM), when streaming compressed audio-video data within the Telco infrastructure in a way that maintains audio-video synchronization and respects the video frame and bit-rate contracts
