Summary
The HEVC video coding standard designed by the Joint Collaborative Team on Video Coding requires nearly 70% more time than the previous standard H.264/AVC to encode a video sequence, because it is computationally more complex than its predecessor. We can take advantage of many-core architectures to reduce the total coding time, and thus, in this paper, we propose the use of an hybrid architecture where intensive computing of intra-picture prediction is performed in GPUs. We have analyzed the sequential intra prediction algorithm in HEVC and we propose a parallel architecture where the sequential thread can be highly parallelized in order to reduce the total coding time.
