Inter Frame-Rate Distortion optimisation on scalable video for HEVC

摘要

Scalable video coding has been highlighted by the High Efficiency Video Coding (HEVC) which has efficient techniques to compress the video size considerably. However, video transmissions over wireless network have remained a challenge due to its limitations on bandwidth and time varying nature of its parameters. This paper presents a novel Inter Frame-Rate Distortion (IF-RD) optimization method for video compression in HEVC using a technique that produces the relationship between levels of transform coefficient and its samples by linear signal model. A quadratic program is used to optimize this problem, however, RD optimization is done on mode selection scheme. The results are presented in the form of Bit rate, PSNR, complexity of computation. The RD improvisation is indicated by Structural Similarity Index (SSI) with respect to Bit rate. Finally the results show a greater improvisation in PSNR, reduction in Computational complexity and increase in SSI. The encoded video can be transmitted in low bandwidth channels like wireless medium.
