Efficient Enhancement for Spatial Scalable Video Coding Transmission
Mathematical Problems in Engineering, 2017
Scalable Video Coding (SVC) is an international standard technique for video compression. It is an extension of H.264 Advanced Video Coding (AVC). In the encoding of video streams by SVC, it is suitable to employ the macroblock (MB) mode because it affords superior coding efficiency. However, the exhaustive mode decision technique that is usually used for SVC increases the computational complexity, resulting in a longer encoding time (ET). Many other algorithms were proposed to solve this problem with imperfection of increasing transmission time (TT) across the network. To minimize the ET and TT, this paper introduces four efficient algorithms based on spatial scalability. The algorithms utilize the mode-distribution correlation between the base layer (BL) and enhancement layers (ELs) and interpolation between the EL frames. The proposed algorithms are of two categories. Those of the first category are based on interlayer residual SVC spatial scalability. They employ two methods, na...

Performance Enhancement for quality inter-layer Scalable Video Coding
One of advanced video coding standard is scalable video coding (SVC) extension of H.264/AVC, SVC provides multimedia service within variable transport environments. SVC is a large computation complexity in encoding processing, through using the exhaustive search technique. The encoding processing included the select macroblock mode and motion vector layer. This paper introduces a new proposed algorithm to reduce this complexity with saving quality. Scalable quality inter-layer performance enhancement (SQILPE) proposed algorithm depends on analysis amount of change in intensity value of pixels in the MB and video statistics. Experimental results show that the proposed fast mode decision algorithm can achieve computational savings up to 77.6% with almost no loss in quality.

Overview of the High Efficiency Video Coding (HEVC) Standard
—High Efficiency Video Coding (HEVC) is currently being prepared as the newest video coding standard of the ITU-T Video Coding Experts Group and the ISO/IEC Moving Picture Experts Group. The main goal of the HEVC standardization effort is to enable significantly improved compression performance relative to existing standards—in the range of 50% bit-rate reduction for equal perceptual video quality. This paper provides an overview of the technical features and characteristics of the HEVC standard. Index Terms—Advanced video coding (AVC), H.264, High Efficiency Video Coding (HEVC), Joint Collaborative Team on Video Coding (JCT-VC), Moving Picture Experts Group (MPEG), MPEG-4, standards, Video Coding Experts Group (VCEG), video compression.
