Multimedia in IMS, including IPTV, is handled by a separate unit, the Media Function (MF), which is made up of Media Control and Media Delivery Functions (MCF & MDF). According to the different specifications of an IMS based IPTV architecture, the User Equipment (UE) is expected to use the RTSP protocol as a media control protocol to interact with the MCF, and gets delivery of media from the MDF...
Rich Media (RM) is a new media concept, which is different from the transitional media such as video, audio etc. Embedded rich media services provide a fresh and interactive user experience. A rich media service contains several scenes, which specifies the layout of the elements. Depending on the concrete service, the representation can include various kinds of element streams. The organization, transporting...
IP networks allow constructing versatile device configurations for multimedia streaming. However, the stochastic nature of the packet-switched data transmission may complicate IP-based implementations of some conventional applications such as analog wired transmission of synchronized multi-channel audio. This paper introduces a multimedia streaming system based on the synchronization of multiple playback...
Real-time streaming media transmission is used widely in computer network, and audio-video synchronization is a key issue. Because of using RTP protocol in data transmission, the synchronization requirements can be solved if the time information in RTP data packets is used effectively. In this paper, combining actual application, RTP data packets are simplified appropriately in sending end, and implementation...
