The recently developed video encoding standard Scalable Video Coding (SVC) is designed as the extension of H.264/ AVC. By employing new techniques such as hierarchal layer encoding, SVC could produce bit streams with different frame rates, bit rates and spatial resolutions; but meanwhile, the computational complexity of video encoder is also increased, which makes optimization of SVC encoding a necessity. In this paper, a novel algorithm is proposed, which utilizes the encoding mode of Base Layer (BL) macroblocks (MBs) to initialize the potential optimal candidate encoding mode list for Enhancement Layer (EL) MBs, by mapping encoding modes onto a Two-Dimensional (2D) map. Experimental results demonstrate that, the proposed algorithm could achieve significantly better and more robust time saving than two recent works while maintaining the video performances. © 2010 IEEE.
