Video encoding for multimedia services over communication networks has significantly advanced in recent years with the development of the highly efficient and flexible H.264/AVC video coding standard and its SVC extension. The emerging H.265/HEVC video coding standard as well as 3D video coding further advance video coding for multimedia communications. This paper first gives an overview of the...

This paper describes a unified VLSI architecture which can be applied to various types of transforms used in MPEG-2/4, H.264, VC-1, AVS and the emerging new video coding standard named HEVC (High Efficiency Video Coding). A novel design named configurable butterfly array (CBA) is also proposed to support both the forward transform and the inverse transform in this unified architecture. Hadamard...

As a 3D extension of the High Efficiency Video Coding (HEVC) standard, 3D-HEVC is developed to improve the coding efficiency of multi-view video. However, the improvement of the coding efficiency is obtained at the expense of a computational complexity increase. How to relieve the computational burden of the encoder is becoming a critical problem in applications. In this paper, a fast encoder d...

The latest High Efficiency Video Coding (HEVC) standard significantly improves coding efficiency over its previous video coding standards. The expense of such improvement is enormous computational complexity, from both encoding and decoding sides. Since computational capability and power capacity are diverse across portable devices, it is necessary to reduce decoding complexity to a target with...

To combat with lagging rate control (RC) parameter setting in encoding video sequences with discontinuous scenes, a novel RC algorithm at group of picture (GOP) level is proposed for high efficiency video coding (HEVC) in this paper. Firstly, the variation of GOP is analyzed and used to detect the discontinuous scene. Then, a new bit allocation algorithm is presented by constructing the correla...

As an approximation to the Discrete Cosine Transform (DCT), Integer Cosine Transform (ICT) is widely used in latest video coding standards, such as H.264/AVC, VC-1 and AVS. High Efficiency Video Coding (HEVC), the next generation of video compression standard, adopts 4/8/16/32 integer transform. Since the size of matrices themselves and the numerical magnitude of matrix elements are very large,...

In this paper, a low-complexity algorithm is proposed to reduce the complexity of depth map compression in the high-efficiency video coding (HEVC)-based 3D video coding (3D-HEVC). Since the depth map and the corresponding texture video represent the same scene in a 3D video, there is a high correlation among the coding information from depth map and texture video. An experimental analysis is pe...

Inter-view residual prediction (IVRP) is employed to efficiently code non-base texture views by exploiting the correlation of residues between two views in 3D video coding extension of HEVC (3D-HEVC). To further improve the performance of texture coding, advanced residual prediction (ARP) is proposed in this paper. In IVRP, residues in a non-base view are predicted from decoded residues in base...
