Comparison of Video Codecs Performance for Real-Time Transmission

Abstract

Nowadays, the need for more efficient video compression algorithms is growing, due to the increasing consumption of video content in higher resolutions. Thus, it is obvious that video compression technologies play a key role in the distribution of video content in broadcasting. In this paper, the video compression comparisons take into account the encoding or decoding time which is needed for each compression standard, in order to provide evidence about their adaptation under real-time streaming conditions. The video test sequences used in our experiments were retrieved from miscellaneous sources and their common characteristic is that they have High or Ultra High Definition resolution. Video codecs' performance was tested by using commercial coding libraries and reference software of the coding standards.
