The widespread of video based applications in nowadays life has increased the need of video coding scalability. In fact, spatial scalability allows the adaptation of the bit-stream to end users as well as varying terminal capabilities and network conditions. In this context, many Discrete Wavelet Transform (DWT) based video codec are proposed. We can sort out that the well known integer to integer...
Motion estimation (ME) is one of the most time-consuming parts in video encoding system, and significantly affects the output quality of an encoded sequence. In this paper, we present hardware implementation of the Large Diamond Parallel search algorithm. This hardware is designed to be used as part of a complete H.264 video coding system. This architecture is simulated and tested using VHDL and synthesized...
Entropy coding is a fundamental stage in all video compression algorithms in terms of compression efficiency and error resilience. In this paper we propose and optimize a digital signal processor (DSP)-based implementation of the CAVLC tools for the H.264 Baseline encoder. As result, we have been able to generate the bit stream and supply bit rate result: the LETI encoder is able to achieve high compression...
