论文摘要
可扩展的视频编码（SVC）从其前身高级视频编码（AVC）扩展，因为它具有灵活的传输到所有类型的小工具。但是，SVC比AVC更灵活，更可扩展，但是在确定计算方面比AVC更为复杂。标准H.264 SVC中的传统完整搜索方法消耗了更多的编码时间进行计算。计算中的这种复杂性需要降低，并且开发了许多快速模式决策（FMD）算法，但是许多人无法在所有三个措施（例如峰信号与噪声比（PSNR），编码时间和比特速率）中平衡。在本文中，基于像素的方向提出的最佳模式选择算法可以获得更好的时间节省，良好的PSNR和编码效率。将提出的算法与标准H.264 JSVM参考软件进行比较，发现为57.44％节省时间，PSNR的0.43 dB增量和比特率的0.23％压缩。
Scalable video coding (SVC) is extended from its predecessor advanced video coding (AVC) because of its flexible transmission to all type of gadgets. However, SVC is more flexible and scalable than AVC, but it is more complex in determining the computations than AVC. The traditional full search method in the standard H.264 SVC consumes more encoding time for computation. This complexity in computation need to be reduced and many fast mode decision (FMD) algorithms were developed, but many fail to balance in all the three measures such as peak signal to noise ratio (PSNR), encoding time and bit rate. In this paper, the proposed optimal mode selection algorithm based on the orientation of pixels achieves better time saving, good PSNR and coding efficiency. The proposed algorithm is compared with the standard H.264 JSVM reference software and found to be 57.44% time saving, 0.43 dB increments in PSNR and 0.23% compression in bit rate.
