Video Multicast using Multiple Description Coding and Rateless Coding Mohamad Ramin Nabati r nabati@ec iut ac ir Date of Submission 7 July 2015 Department of Electrical and Computer Engineering Isfahan University of Technology Isfahan 84156 83111 Iran Degree M Sc Language Farsi Supervisor Dr Faramarz Hendessi hendessi@cc iut ac irABSTRACTVideo delivery in packet switched networks like the Internet is a challenging issue Internet provides a best effortservice meaning that there is no quality of service guarantee in the current Internet and network parameters like thebandwidth delay and packet loss probability vary dynamically in the network Besides other issues like optimal videomulticasting and fare bandwidth allocation between video streams and other traffics in the network remain to besolved In this thesis we first review the concepts of Multiple Description Coding and Rateless Coding and thenpropose a new method for multicasting video on IP based networks In the proposed method we used both multipledescription coding and rateless coding to make video streams more resilient against packet loss in the network and inaddition provide different quality levels for heterogeneous users In this method we used even odd frames separationto create two descriptions from the original video and Raptor codng is used for the rateless coding part Formulticasting the video on the network we proposed an algorithm for receiving feedbacks from the users to control theamount of overhead sent by the server according to the packet loss probability This algorithm keeps the number offeedback messages minimum in order to prevent congestion in the server side or the network Finally the simulationresults are provided and the proposed method is compared to simple multicasting of the video The simulation resultsindicate a great improvement in the users video quality KEYWORDS Video Multicasting Multiple Description Coding Rateless Coding
