Abstract

This paper describes a real-time 4K/60p High Efficiency Video Coding (HEVC, the latest coding standard) multi-bitrate encoding system with content-aware bitrate control. Our encoding system has multiple encoding core LSIs that can each encode 4K/60p or up to HD x 4 streams. To reduce streaming bandwidth consumption, the encoding channels adopt dynamic seamless bitrate control, which is based on content aware bitrate control and supports multi- channel real-time encoding for adaptive bitrate streaming. Experimental results show the system reduces bitrates obtained with constant bitrate encoding by as much as 56.7%.
