Study on Parallel Approach in H.26L Video Encoder
H. 26L is an emerging video encoding standard proposed by ITU, which goal is for video communication and multicast in Iow bit rate conditions. This paper gives detailed analysis and performance tests for the parallelism of the H.26L video encoder test model long-term (TML8.0).Based on these tests, several parallel schedule strategies are discussed in different aspects, and the optimal one is selected and implemented by using MPI. At last,experiment results on Dawning-2000 MPP machines with different processors are given. The analysis and simulation results show that the H.26L has a good parallel performance and scalability on slice layer, and parallel computing can greatly speed up the processing of H.26L encoder. The experiment methods and results can be applied to many parallel systems for H.26L video processing.
