HEVC(High Efficiency Video Coding) is a new generation of video coding standard which is proposed by ITU-T VCEG and ISO/IEC MPEG for the increasingly widespread application of high-definition video. On the basis of original DCT transform of H.264, HEVC has proposed a DST transform with the size of 4×4.We design the hardware structure of pipelined DST by analyzing software algorithm, according to the...
H.264FRext video coding standard uses integer 8 × 8 discrete cosine transform (DCT) algorithm. It can preserve the detail image information better. Compared with the traditional cosine transform, integer DCT can avoid the mismatch problem, increase the computation speed, and is more feasible for hardware implementation. This paper proposes a novel two-dimension DCT hardware structure based on the...
In this paper, a fast inter-frame mode selection algorithm based on texture is proposed. The algorithm uses three model sets, the macro block level, the sub-macroblock level and the block level to divide all 7 inter modes. There are three methods of texture analysis to determine the best reference mode on the each level. The final decision is made by calculating the RDO-cost of the three optimal level...
This paper presents a novel video encoding algorithm using the technique of Hybrid Vector Quantization (HVQ). Two modes of operations are defined in the encoder part, i.e. intra-mode and inter-mode. A blended algorithm based on Mean Coding and Conventional VQ (MCCVQ) using an intra-codebook is adopted for the intra-mode of operation. In the inter-mode of operation, no-encode sub-mode is for static...
