P2P Video Multicast for Wireless Mobile Clients
نویسندگان
چکیده
Mobile TV is a new interesting area in the telecommunication industry. The technology for sending live video to mobile clients is characterized by relatively low CPU processing power, low network resources and low display resolution. In this paper we discuss a solution to all of these problems by using application layer multicasting. This can significantly reduce the needed bitrate and required computing resources for each client. At the same time the received video quality is increased. Several different methods for splitting the video into substreams are discussed. A system for application layer multicasting using layered H.264 is also presented.

متن کاملA Video Gateway to Support Video Streaming to Mobile Clients
This paper describes how video streaming from or to mobile participants of a video conference can be supported by a so called “Mobility Gateway“. The gateway interconnects a mobile client, through a wireless link, to a fixed network LAN or WAN multicast environment and performs intelligent operations on the video stream like transcoding, congestion control etc. in order to provide the mobile us...
متن کاملA Survey on Multicast Routing Approaches in Wireless Mesh Networks
Wireless mesh networks (WMNs) which mediates the broadband Internet access, have been recently received many attentions by the researchers. In order to increase capacity in these networks, nodes are equipped with multiple radios tuned on multiple channels emerging multi radio multi-channel WMNs (MRMC WMNs). Therefore, a vital challenge that poses in MRMC WMNs is how to properly assign channels ...

متن کاملProviding VCR in a Distributed Client Collaborative Multicast Video Delivery Scheme
In order to design a high scalable video delivery technology for VoD systems, two representative solutions have been developed: multicast and P2P. Each of them has limitations when it has to implement VCR interactions to offer true-VoD services. With multicast delivery schemes, part of system resources has to be exclusively allocated in order to implement VCR operations, therefore the initial V...
