High Efficient video coding (HEVC) will be replacing the current standard, H.264/MPEG-4 Advanced Video Coding (AVC). The main goal for HEVC standardization is to deliver equal video quality for half the bit-rate of H.264/MPEG-4 AVC. Other objective of HEVC is to support higher resolution than the current high definition (HD) of 1920 × 1080. Nevertheless, HEVC standard has similar structure design of previous standard but with new enhancement and improvement. This paper will briefly highlight new technical features in HEVC standard. Main focus in HEVC investigation will be enhancement, changes and improvement compared to H.264/MPEG-4 AVC. In addition, test is performed by using HEVC reference software (HM 12.0) comparing with H.264/MPEG-4 AVC reference software (JM 18.5). Moreover, different configuration of HEVC encoder will be tested, exclusively in intra/inter-picture configuration, entropy coding setting, de-blocking filters and sample adaptive offset (SAO), comparing its performances with H.264/MPEG4 AVC. Test sequences used in the experiment consist of different resolution and frame rate. The experiment objective is to examine the capabilities of HEVC in delivering equal or higher quality videos by using objective quality measurement peak signal to noise ratio (PSNR). All of data collected will be fitted using rate-distortion (RD) curves.
