Tiivistelmä
This paper describes a demonstration setup for real-time 4K HEVC intra coding. The system is built on Kvazaar open-source HEVC encoder partitioned between 22-core Xeon processor and two Arria 10 FPGAs. The demonstrator supports 1) live streaming of up to three 4K30p videos; or 2) offline video streaming up to 4K100p format. Live feeds are shot by three cameras whereas offline video is accessed from a local hard drive. In both cases, encoded bit stream is sent over a wired connection and played back by laptop(s). The demonstrated HEVC coding speed is over three times as fast as that of a pure software solution.
