Delivering multimedia streaming on Internet remains several limitations, such as bandwidth fluctuations and network conjunction. We present a multimedia gateway design including dynamic bandwidth estimation, SVC extractor and buffer management to resolve the limitations. The dynamic bandwidth estimation not only selects the appropriate SVC sub-stream, but also measures the change of bandwidth and...
IP multicast has proved to be the best approach for large scale multimedia communications enhancing video transmissions for applications like IPTV, video conferencing or other best-effort real-time audio/video applications. IP multicast connectivity, unfortunately, relays on certain network technologies and protocols and is present only in some areas of the Internet, while the majority of hosts lack...
A scheme that exploits the broadcast nature of the wireless communication in order to achieve multicast content delivery is presented in this paper. As opposed to broadcasting, this method enables the clients to determine on-line the delivered content, and thus preserves the advantages of an individual service. On the other hand, a multicast content delivery is much more efficient than a unicast content...
Video-streaming can now be offered on third-generation (3G) mobile networks. Most research efforts have focused on video download. This paper presents a detailed study of challenges faced for successfully deploying applications requiring life video upload. Both subjective and objective qualities as well as the effects of mobility are analyzed on real 3G networks. Consequently, video profiles are identified...
