Abstract

So far an efficient coding scheme for ultra high resolution (8K) video under a low bit-rate condition has not yet been proposed. Within H.264 coding framework, highly efficient coding is realized due to the optimal control for the macroblock (MB) coding mode decision. However, coding modes available in H.264 coding are not necessarily appropriate for 8K full resolution coding under the considerably low bit-rate condition, and satisfactory coding performance cannot be achieved within H.264. In this paper, we propose to define the extended coding mode from the analytical result of R-D performance by conventional coding modes. From coding experiments, it was confirmed that the maximum coding gain reached 0.18dB at the target bit-rate assumed in this study.
