Abstract

This paper presents a technical review to real time Video Multicast. In this paper Video Multicast technique is being described and to improve the quality and efficiency using network coding and video data compression. Video data compression is concerned with reducing the amount of data required to reproduce a digital video. It is a key component in facilitating the widespread use of digital video, which is currently prevented by the mismatch between the huge storage and transmission bandwidth requirements of video and the limited capacity of existing computer systems and communications networks. In this paper we provide measure to remove the problem of video multicast in lossy networks using data compression, network coding and multiple description codes. The rate allocation for multiple descriptions can be optimized at the source to generate a scalable video bit stream such that the expected PSNR of the video at the receivers is maximized. Here we implement Huffman Coding as it is being lossless data compression. Although the range of video compression standards now available, such as H.261 or MPEG-2, exhibit acceptable performance when operating at high bit rates (eg >64 Kbps) and we can implement these. .
