In this paper we propose and evaluate a combined SVC-MDC (Scalable Video Coding & Multiple Description Video Coding) video coding scheme for Peer-to-Peer (P2P) video multicast. The proposed scheme is based on a full cooperation established between the peer sites, which contribute their upload capacity during video distribution. The source site splits the video content into many small blocks and...

Very Low Bitrate coding at below 64 kbit/s will be a crucial technique in forthcoming visual services such as video phone and multimedia system. The trend of increasing interest in, and demand for, telecommunication, interactive TV and Multimedia services, has led to significant acceleration of video coding research worldwide. The reference model method for developing the H.261 video coding alg...

In this letter we present an improved distributed video coding (DVC) scheme based on polar techniques. Firstly, adapt log-likelihood ratios (LLRs) for DVC with integer implementation of a discrete cosine transform (DCT). We propose computationally efficient and numerically stable modification these LLRs the simplified methods codes decoding. show that average approach provides 0.3 dB PSNR gain ...

Technologies for coding non-camera-captured video contents have received great interests lately due to the rapid growth of application areas such as wireless display and screen sharing, etc. In response to the market demands, the ITU-T Video Coding Expert Group and ISO/IEC Motion Picture Expert Group have jointly launched a new standardization project, i.e. the HighEfficiency Video Coding (HEVC...

To provide users with more realistic visual experiences, videos are developing in the trends of Ultra High Definition (UHD), Frame Rate (HFR), Dynamic Range (HDR), Wide Color Gammut (WCG), and high clarity. However, data amount increases exponentially, which requires efficiency video compression for storage network transmission. Perceptually optimized coding aims to maximize by exploiting redun...

In this paper, the authors describe two methods designed for reducing spatiotemporal redundancy of video within MPEG Immersive (MIV) encoder: patch occupation modification and cluster splitting. These allow optimizing important parameters immersive video: bitrate pixelrate. The method significantly decreases number active pixels texture depth produced by MIV encoder. Cluster splitting total are...
