Abstract—High definition videos (HDVs) have captured the current market of video coding and media. Keeping in view of that Joint Collaborative Team on Video Coding (JCTVC) developed a video coding standard known as High Efficiency Video Coding (HEVC). It is a state-of-the-art video coding tool but its performance suffers from blocking artifacts to achieve high compression ratio. HEVC is thus equipped with the in-loop filter for suppressing of blocking artifacts. This paper describes the comparative analysis of HEVC in-loop filter which comprises of de-blocking and sample adaptive offset (SAO) filters. Various high definition video sequences of 1080p and 720p are used for comparing results of with or without in-loop filtering. Simulation results that in-loop filter can suppress blocking artifacts effectively without losing subjectivity of video.

Index Terms—high definition video, HEVC, in-loop filtering, de-blocking filter, performance analysis
