Evaluation of Performance Ip-tv in Wimax Network

Abstract

-The future of television is undoubtedly internet Protocol Television(IPTV), given its ability to give users the ability to interact with the video they watched. The expansion of this new diffusion technique could be promoted using Worldwide Interoperability for Microwave Access (WiMax) technology to serve areas not accessible by wireline technologies. Then, with the discovery of new compression technique such as H.265 standard, it could operate on high-quality videos. This dissertation aimed to analyze and optimize IPTV performance using WiMax technology as an access support and the H.265 standard as compression standard, focusing on the choice of the more favorable buffer size. The results obtained in the simulations show that the buffer size customers WiMax stations to broadcast high-definition video must be greater than 256KB for proper reception of images component video, and to avoid poor visual quality.
