Performance Evaluation of HEVC over Broadband Networks

High efficiency video coding is the current trend setting standard for coding and transmission of video content. This standard has brought in many improvements over its predecessor H264 standard. In this paper, performance evaluation of transmitting HEVC content over the simulated network environment for disaster and calamity stricken area has been under taken. In the simulation the transmitted video sequences are subjected to various error models in NS3 simulator. The effects of speed and number of hosts on the jitter and delay characteristics of the underlying network while transmitting flows of HEVC based content has been evaluated. The extent and effect of network errors on the quality of HEVC bit stream in terms PSNR has also been tested. The results show that HEVC performs better for up to 0.001 percent network error, for up to 30 simultaneously transmitting nodes and for nodes travelling at speeds up to 100m/s.
