One of the major challenges for video collaboration lies in video conferencing in low bandwidth and low cost. In this paper we discuss about a server less desktop based video conferencing application that has been built around a highly bandwidth efficient H.264 video compression technology. The proposed solution offers a low cost multiparty video conferencing solution suitable for corporate environment...
The broadcast method is the most efficient approach to deliver a popular video for utilizing bandwidth. By combining the Fibonacci and staircase methods, this paper presents a hybrid broadcasting method with low buffer requirement to deliver a constant bitrate compressed video. The proposed method allows users with bandwidth of double of the consumption rate to download and watch the video without...
With the rapid development of video streaming era, multipath video streaming comes as a promising solution. However, dividing the video into different sub-streams is still considered as an important challenge for researchers. In this paper, we propose an approach for generating multiple complementary descriptions of the video flow, then to couple these descriptions with the path diversity provided...
Research into high quality media streaming is regarded as an important area of information technology with the rapid development of network technology and digital A/V home appliances. However, a scheme that can flexibly deal with extreme network dynamics is required to realize high quality media streaming service because the modern internet is designed for best effort services. In this paper, we design...
Internet video on demand is a new application provided by peer to peer network. Thousands of users are using real multimedia streaming systems like PPlive and PPstream which are the killer applications in the Internet. But jitters are always happening during rush time especially when users are watching less popular videos with low bandwidth network. To improve this, a cache scheduling scheme based...
The emerging scalable video coding extension in H.264/AVC standard will enable the deployment of video streaming and distribution applications in heterogeneous environments, with different user bandwidth resources and display capacities. In this paper, we study the problem of how to distribute scalable coded media objects from a media distribution server in peer-to-peer based IPTV applications. All...
Most algorithms of smoothing schedule compute the required bit rate of the video transmission to satisfy all the transmitted data. MPEG-4 with fine grained scalability supports partial data dropping to adapt to available bandwidth network. In this paper, our proposed dropping algorithm can adjust the transmitting data to fit the available bit rate. Our algorithm is based on the minimum variance bandwidth...
More and more, multimedia services are being accessed via fixed and mobile networks. These services are typically much more sensitive to packet loss, delay and/or congestion than traditional services. In particular, multimedia data is often time critical and, as a result, network issues are not well tolerated and significantly deteriorate the userpsilas quality of experience (QoE). We therefore propose...
