Abstract : H.264 is the latest video coding standard, which is also known as MPEG-4 Part 10, or MPEG-4 AVC (Advanced Video Coding). It was published in early 2003 by the ITU-T Video Coding Experts Group (VCEG), together with the Moving Picture Experts Group (MPEG).The main goals of the H.264/AVC standardization is to enhance compression performance and to provide a “network friendly” video representation addressing “conversational” (video telephony) and “non conversational” (storage, broadcast, or streaming) applications. For the transmission of standard definition (SD) and high definition (HD) TV signals over satellite, cable and terrestrial emission and the storage of high-quality SD video signals onto DVDs require a higher coding efficiency which can be offered by H.264/AVC standard, but this comes at the cost of veryhigh computational complexity.H.264 is reportedly able to achieve high coding efficiency with the reduction of bit rate more than 50% in average. A significant improvement in the rate-distortion has been achieved by H.264 in comparison to previously existing standards( MPEG-1, MPEG-2...). HEVC makes use of prediction to exploit redundancies in the signal and therefore achieve high compression efficiency. In particular, the Intra frame prediction block consists of predicting a block in the current frame using the reference information from neighboring blocks in the same frame. It supports 9 different modes based on directions. The objectiveis to improve Intra frame prediction block, with the goal of drastically reducing computational complexity and at the same time achieving comparable compression efficiency as conventional HEVC. Keywords - High Efficiency Video Coding, Video Coding, Intra Frame Prediction, Advanced Video Coding, Moving Picture Expert Group, Prediction Block.
