Efficient Receiver-Driven Layered Video Multicast using 263+ SNR Scalability

چکیده
In this paper we discuss the implementation of receiver-driven rate adaptation using multicast and SNR scalability as supported by Version 2 of ITU-T Recommendation H.263 -Video Coding for Low Bit Rate Communication. We compare the layered bit stream approach to receiver-driven rate adaptivity to the approach using multiple independent bit streams. We show that although the independent, non-scalable bit streams perform better in a rate-distortion sense at the receiver, the layered bit streams cause less congestion at the intermediate network segments.

Low-Complexity Video Coding for Receiver-Driven Layered Multicast
In recent years the “Internet Multicast Backbone”, or MBone, has risen from a small, research curiosity to a large scale and widely used communications infrastructure. A driving force behind this growth was the development of multipoint audio, video, and shared whiteboard conferencing applications. Because these real-time media are transmitted at a uniform rate to all the receivers in the netwo...

متن کاملStability and Fairness Issues in Layered Multicast
Layered multicast is a promising technique for broadcasting adaptive-quality video to heterogeneous receivers. Past evaluation of layered multicast protocols has focused on the effectiveness of determining the maximal number of layers that can be delivered to each receiver. Unfortunately, this is only a partial metric and does not capture all aspects of the “viewing experience”. This paper exte...

Securing the multicast communication model is a strategic requirement for effective deployment of large scale business multi-party applications (TV over Internet, Video-on-Demand (VoD), video-conferencing, interactive group games, .). One of the main issues in securing multicast communication is the authentication service; a keystone of every secure architecture. Even though several authenticat...
