“…Selecting the best mode of intra prediction is done according to the minimum rate distortion, which is the result of comparison between the predicted MB and source MB. The metric of distortion used in almost all encoder implementations is the sum of absolute difference, thanks to its simplicity and effectiveness [20]. Then, the residual MB is encoded, which is the difference between the source MB and predicted MB.…”

“…Two kinds of DLP exist: CLP and DSLP. Compared with TLP, DLP seems to be the best way for obtaining a maximum decrease in execution time [20, 24, 25]. Baaklini et al [26] proposed a CLP for H.264 decoder, which consists in assigning luma and chroma processing to separate CPUs.…”

“…The best mode of intra prediction is selected based on the minimum rate distortion, which is the result of a comparison among the predicted block and source block. The distortion metric applied in almost all encoder implementations, is the Sum of Absolute Difference (SAD) (Kim, 2011), due to its simplicity and effectiveness. Then, the predicted MB is subtracted from the source MB to form the residual block.…”

Using multiprocessor technology is an interesting solution for reducing the processing time of complex video encoders such as H.264/Advanced Video Coding (AVC). This paper details different levels of parallelism presented in related works for H.264/AVC encoder. An efficient Macro Blocks Line level parallelism for the intra prediction encoding chain of H.264/AVC for High Definition (HD) video is proposed. It is implemented on MPSoC architecture using an open and free platform for virtual prototyping named SoCLib. Comparing to related works, the proposed partitioning meets strongly the size of required memory constraint and provides an interesting speed-up. The proposed architecture is based on three processors and ensures a reduced circuit area. Experimental results reveal a run time saving of about 59.8% in terms of processing speed, compared to a classical execution based on a single CPU, without affecting the quality of the reconstructed video.

“…Many researchers have proposed the fast encoding algorithms [4][5][6][7][8][9][10][11][12][13][14][15] for AVC/H.264. There are two categories in fast encoding algorithms: fast intra prediction methods [16][17][18][19][20][21][22][23] and fast inter prediction methods.…”

For the higher coding performance than the previous video coding standards, high efficiency video coding (HEVC) adopts an angular intra prediction method, which requires heavy computational complexity due to the increased intra prediction modes. In this paper, we propose a fast intra prediction mode decision based on the estimation of rate distortion cost using Hadamard transform to reduce the number of intra prediction mode and early termination whether the current coding unit is splitted or not. The experimental results show that the proposed method reduces the computational complexity of intra prediction in HEVC and achieves similar coding performance to that of HEVC test mode 2.1
