This paper proposes a group of macroblock (GOMB) based motion estimation (ME) algorithm supporting adaptive search range (ASR) for H.264 video coding. Adopting the concept of GOMB to generate the Predicted Motion Vector (PMV) for doing H.264 ME achieves good results in balancing the computational complexity, video quality and memory bandwidth. Moreover, it supports adaptive search range (ASR) in doing...
This paper presents a new error concealment algorithm, which is suitable for the H.264/AVC coding standard and the hardware implementation. This algorithm can be dividing into two major categories. In the spatial domain, we use the reliable neighboring pixel values with edge detection method to conceal all the lost pixels in the block. In the temporal domain, we propose a variable block size error...
In this paper a low cost and low power multi-mode entropy decoder is proposed. The proposed design is compatible to the entropy decoding for JPEG, MPEG-1/2/4, H.264 and VC-1 video coding standards. It adopts the code-word tables merging and sharing, and integrates the various entropy decoding into a single programmable design. To reduce the required memory space, a generic look-up table partition...
This paper proposes a performance-aware transform IP design which can be configured to appropriate hardware for different performance requirements on demand without requiring additional data bandwidth in multimode video coding (JPEG/MPEG-1/2/4/H.261/H.263/H.264). Based on the scalable-DA approach, three schemes of hardware configurations which are respectively composed of 3, 6, and 12 data-paths are...
This paper presents a high performance VLSI architecture design for MPEG-4 AVC/H.264 CAVLC encoding. In the proposed design, we propose a forward-based parallel coding (FPC) technique to increase the data throughput rate. Moreover, two approaches called arithmetic table elimination (ATE) and fast look-up table matching (FLM) are exploited to reduce the hardware cost. With the synthesis constraint...
