دانلود myEvalSVC: an Integrated Simulation Framework for Evaluation of H.264/SVC Transmission

Abstract

The  ever-increasing  demand  for  H.264  scalable  video  coding  (H.264/SVC)  distribution motivates researchers to devise ways to enhance the quality of video delivered on the Internet. Furthermore,  researchers  and  practitioners  in  general  depend  on  computer  simulators  to analyze  or  evaluate  their  designed  network  architecture  or proposed  protocols.  Therefore, a complete  toolset,  which  is  called  myEvalSVC,  for  evaluating  the  delivered  quality  of H.264/SVC  transmissions  in  a  simulated  environment  is  proposed  to  help  the  network  and video coding research communities. The toolset is based on the H.264 Scalable Video coding streaming Evaluation Framework (SVEF) and extended to connect to the NS2 simulator. With this combination, people who work on video coding can simulate the effects of a more realistic network on video sequences resulting from their coding schemes, while people who work on network technology can evaluate the impact of real video  streams  on the  proposed  network architecture  or  protocols.  To  demonstrate  the  usefulness  of  the  proposed  new toolset, examples of H.264/SVC transmissions over 802.11 and 802.11e are provided.
