摘要

With the advent of smartphones and tablets, the amount of online video traffic has increased enormously. This, together with the growing popularity of high-definition video, motivated the development of the High Efficiency Video Coding (HEVC) standard, released in 2013, with the aim of achieving a 50% bitrate reduction with respect to its predecessor, namely H.264/MPEG-4 Advanced Video Coding (AVC). However, new contents with greater resolutions and requirements arise every day, making it necessary to reduce the bitrate to a further extent. In this regard, the efforts to become the leading video codec in the market resulted in two main contenders: the Joint Video Experts Team (JVET), which leads the development of the Versatile Video Coding (VVC) standard, and the Alliance for Open Media (AOMedia), which spearheads the AOMedia Video 1 (AVI) project. In this context, this paper presents a rate-distortion/complexity analysis of HEVC, VVC and AVI main video codecs using objective measures of assessment in order to analyze their real capabilities. The analysis, which was done using well-defined test conditions, reveals that VVC considerably outperforms both HEVC and AVI in terms of coding efficiency.
