Resumo


The recent growth of high definition multimedia applications imposes several restrictions to traditional ISO MPEG-x e ITU-T H.26x video encoders. Considering that, the most recent international standard, H.264 codec, includes several new algorithms in order to increase compression efficiency and application flexibility. Unfortunately this improved technology demands very high performance to support real-time video encoding. Considering this scenario, the current paper proposes the adoption of the GPU NVidia CUDA® technology as development platform to increase performance of a H.264 intra video encoder. Practical results comparing the proposed solution with the original H.264/AVC reference code points to significant performance gains for high definition computing.
