英文摘要: With a new video coding standard high efficiency video coding (HEVC), the ultra high definition (UHD) TV service with robust video streaming technology is emerging in the TV industry. This paper addresses the system architecture for the UHD video streaming and proposes three main ideas: (i) picture prioritization method, (ii) error concealment mode signaling (ECMS), and (iii) Tile complexity-based parallel video processing. In the experiments using HEVC reference model conducted, the proposed picture prioritization method shows the gains in video quality from 2.2 to 7.5 dB in Y-PSNR, and the error concealment mode signaling gains from 0.2 to 2.5 dB in Y-PSNR, with corresponding subjective improvements. In addition, proposed parallel processing method for real-time decoding shows around...
