摘要
随着网络多媒体技术的高速发展以及H.265/HEVC视频编解码标准的不断运用,如何高效地进行视频编码是值得关注的热点之一。针对高效编码视频序列的问题,基于H.265/HEVC帧间预测过程中的运动估计原理以及对视频图像最优点的概率统计,加入判断提前终止搜索条件,提出一种基于改进TZsearch的快速编码算法,有效降低了视频编码时间。通过对经典视频序列的编码验证和对比,改进TZsearch算法在满足编码质量的同时降低编码时间15.37%,更加准确、高效地实现了视频编码。
With the rapid development of network multimedia technology and the continuous application of H.265/HEVC video codec standard, how to encode video efficiently is one of the hotspots worthy of attention. Aiming at the problem of efficient coding of video sequences, based on the motion estimation principle in the process of H.265/HEVC inter prediction and the probability statistics of the best advantage of SS video image, adding the judgment early termination search condition, a fast coding algorithm based on improved TZsearch is proposed, which effectively reduces the video coding time. Through the coding verification and comparison of classical video sequences, the improved TZsearch algorithm not only meets the coding quality, but also reduces the coding time by 15.37%, and realizes video coding more accurately and efficiently.
