The SHVC (Scalable High Efficiency Video Coding) standard developed as an extension to H.265 HEVC (High Efficiency Video Coding) that focus on data transmission over heterogeneous network with wide scalability. In this paper a Superior Step Search (SSS) algorithm is proposed to enhance the PSNR performance along with coding efficiency without much increase in the computational complexity. The proposed SSS algorithm performs dynamic search to predict the best matching block using a fine search pattern. Simulation results show 0.5% average increased performance in PSNR and 32% coding efficiency in Bit rate when compared with the SHM reference software. Keywords: Coding efficiency, Computational complexity, PSNR, Bit rate, Time
