Abstract

The importance of video coding standards increases with the growing usage of digital video transmission.

Although High Efficiency Video Coding (HEVC) and its predecessor Advanced Video Coding (AVC) have

many similarities, HEVC does a better job at digital video coding. Multiple reference frames can be used in

inter prediction of HEVC. There are several different approaches that exist in the literature. Main idea of

modern video coding techniques is to differential coding of blocks by referencing previously coded similar

blocks so that less data is required to be sent. In this paper, multi reference blocks are used for inter prediction

process. The method selects multiple reference blocks using SAD and creates predicted blocks via a weighted

average of the selected references. Weights of the selected references were calculated with the least-squares

approach. Candidate references are determined within a few blocks with lowest SAD values. Experimental

results show that the proposed method leads to an increase in PSNR values.
