    • Abstract:
      The live broadcasting of game playing is becoming more and more popular. The game video is one of the typical video data which should be coded with high efficiency video coding-screen content coding (HEVC-SCC). In HEVC-SCC, the palette mode is an important technique which can effectively enhance the coding performance. However, this technique also demands high-coding computation. In this paper, we propose a fast palette mode pre-decision method based on the analysis of the color complexity of the video data. Considering only the coding computation of palette mode of HEVC-SCC, our algorithm saves about 74.24% computation in the experiments of game videos. Whereas, the BDBR only increases by about 0.36% and the BDPSNR decreases by about 0.03 dB on average. [ABSTRACT FROM AUTHOR]
