چکیده

H.264/AVC is a joint project of ITU and MPEG. It provides high quality compression for various services like IP streaming media, SDTV and HDTV broadcast and video on demand etc. Motion estimation, input buffer, summation unit and reference frame section form complex design of H.264/AVC encoder. It is the most advanced video standard. In this paper,H.264/AVC encoder is designed in verilog with better performance and optimized structure. Design is finally implemented on FPGA platform. Index Terms H.264/AVC, 3DDCT, Encoder, Implementation, FPGA, Complexity ________________________________________________________________________________________________________

An Efficient Implementation of the Entire Transforms in the H.264/AVC Encoder using VHDL

Received Aug 2, 2013 Revised Oct 14, 2013 Accepted Oct 28, 2013 The H.264/AVC standard achieves remarkable higher compression performance than the previous MPEG and H.26X standards. One of the computationally intensive units in the MPEG and H.26X video coding families is the Discrete Cosine Transform (DCT). In this paper, we propose an efficient implementation of the DCT, inverse DCTs and the H...

A Unified Architecture for Implementation of the Entire Transforms in the H.264/AVC Encoder

Integer Discrete Cosine Transform (DCT) is among the techniques used to improve the performance of the H.264/AVC Standard. All the profiles in the H.264/AVC standard support 4×4 integer DCT and the high profiles of this standard support 8×8 integer DCT as well as the 4×4 integer DCT. Various hardware realizations have been proposed for forward and inverse integer DCT in the literature because t...

−− This paper presents the architecture and the VHDL design of the integer TwoDimensional Discrete Cosine Transform (2-D DCT) used in the H.264/AVC codecs. The forward and inverse 2-D DCT architectures were designed and their synthesis results mapped to Altera FPGAs are presented. The 2-D DCT calculation is performed by exploring the separability property, in such way, each 2-D DCT architecture...

Fast Intra Mode Decision Using DCT Coefficient Distribution in H.264/AVC

The rate-distortion optimization (RDO) method in the H.264/AVC encoder is an informative technology that improves the coding efficiency, but increases the computational complexity. In this letter, a fast Intra mode decision algorithm using DCT (Discrete Cosine Transform) coefficients distribution is proposed to reduce the H.264 encoder complexity. The proposed method reduces the encoder complex...
