A receiver is associated with one of the descriptions. A receiver links different description to meet their bandwidth necessity.Streaming quality at receiver side is related to the number of descriptions received. So it is important but big problem for MDC cinematic multicast is assigning bandwidth to each description in order to make best use of available bandwidth so that user satisfaction can be maximize.In this paper we tried to find how to assign bandwidth for descriptions to make maximize use of available bandwidth and formulate this problem as optimal problem. 1.Introduction: Internet has been around which greatly changed the way market is operated and process of business all over the world. World become very small due to communication facilities growth of internet really changed the life of people. Broadband internet paved the way for live streaming video such as football matches and other live events. This greatly enhanced the way content is transferred to many users at a time. Videos are bulky and need techniques of compression. This has led to many companies to develop portals that exclusively deal with videos services over internet [3]. Many user need multicasting of a live video concurrently as shown in figure1 In figure video streaming being accessed by multiple users of Internet with different devices. It is clear from the figure multiple users able to access video with heterogeneous bandwidth requirement because each user may have devices of different bandwidth and configuration containing varied RAM and processing capabilities. This kind of example can be seen in YouTube, MSN. Online Streaming such as Splitstream, Coopnet, AT&T, PTV, PPLie and AT &T are some examples. The registered users are provided live streaming by these vendors. This can’t be achieved easily because it throws some problems. One of the major problems is optimal allocation of bandwidth because, user bandwidth requirement is different because user have devices of varying bandwidth, such as mobile devices, laptop, smartphones, HD-TV. This also means that user’s bandwidth requirement is not fixed. Assignment of bandwidth with fair quality in video streaming which increases user contentment is the challenging task to be addressed.
