Code Improvements Towards Implementing HEVC Decoder

Abstract

HEVC is the latest video coding standard achieving better compression as compared to previous standards but at a higher complexity. Many applications require fast and real-time decoding of compressed video for which Field Programmable Gate Array (FPGA) is one of the efficient options. In this paper we provide the code improvement and implementation of the computationally intensive HEVC decoder. We describe our investigation for the implementation of HEVC decoder on Visual C++ 2008 platform and present improvements to the code of HEVC decoder required prior to its conversion to a hardware description language. The results for decoding time are also provided.
