Title : Inter Prediction Mode Decision for Fast UHD HEVC Encoders
Date: Thursday, 16th Mar@17:00
Abstract : High Efficiency Video Coding (HEVC) is the latest video coding standard.
It has been designed to meet the demands for ultra-high definition (UHD) services. Although it can provide up to twice better compression efficiency than its predecessor, H.264/Advanced Video Coding (AVC), its high encoding complexity, especially in the inter prediction, is a main obstacle for practical applications. Herein, a most probable inter prediction mode (MPIM) decision method is proposed to reduce the inter frame encoding complexity of HEVC. Experimental results show that the proposed method can provide on average 51.46% encoder speed-up for an average 0.30% bitrate increase in random access main configuration with UHD videos compared to the HEVC test model (HM) 16.13 reference software. The respective values compared to Turing open source codec with slow preset are 55.85% and 0.46%.
