Efficient Algorithm for Scalable High Efficiency Video Coding Intra Prediction process

The Scalable High Efficiency Video Coding (SHVC) standard is a state-of-the-art technology for scalable video coding that uses an exhaustive prediction mode decision algorithm within a recursive quad-tree structure coding unit to enhance coding efficiency. However, this improvement comes at the cost of increased computational complexity during encoding, which poses a challenge. To address this challenge, a novel approach has been proposed to accelerate the SHVC encoder. The proposed technique leverages the inherent spatial correlation between the selected Prediction Unit (PU) within the enhancement layer (EL) and its corresponding PU in the base layer (BL). This strategic exploitation yields impressive results, as evidenced by significant reductions in encoding time. It is worth noting that this efficiency boost is achieved with a manageable compromise in video quality and an acceptable uptick in bit rate, which remains well within the bounds of mainstream media requirements. In practice, the proposed methodology showcases its prowess by consistently achieving an average time-saving of 81.77% and 81.59%, thereby underscoring its effectiveness in practical scenarios.
