An Efficient Video Transmission by Reducing the Packet Loss Using HEVC
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 5
Abstract
to protect real-time video transmission over unreliable networks, packet-level forward error correction (fec) codes are widely studied. When the number of redundancy packets are determined, with fec coding block size the performance of fec coding improves. The decoding delay for a real-time video transmission cannot be tolerable and the packet loss in one frame affects not only the current frame, but all the other frames which is associated with that frame. Lesser bit error rate is achieved in the fec coding compared to the conventional coding. To reduce the video size, and get a better transmission without loss of packets which would give a better quality of video causing less delay during the video transmission, fec coding method is applied to a real-time video streaming scheme which is known as high efficiency video coding( hevc). In this scheme, there is not only improvement in the compression ratio but also in the quality of frame. No delay will be caused for waiting for the video or parity packets of the following frames both at encoding and decoding sides, since video packets of the frames are not encompassed in the hevc block. The performance is excellent, but it can still be improved when burst packet loss occurs. In this paper, a novel scheme is proposed by replacing randomized expanding reed-solomon (re-rs) scheme with hevc scheme to get improved compression ratio and good quality frames. Therefore packet loss is evaded in a video by reducing the number of frames and increasing its quality of video by applying fec coding to hevc instead of re-rs scheme which improves the compression ratio and causes less delay during video transmission. As a result, we simply get a good quality video with lesser frames and less delay during any video transmission.
