High Efficiency Video Coding (HEVC) [1,2] is a next generation video coding standard which has the potential to improve delivery of High Definition and Ultra High Definition video.  A HEVC analyser is software with a user-friendly interface for visualising and testing of HEVC bitstreams. It can be a useful tool for broadcasters and content delivery professionals, quality assurance teams, educators, codec architects and for anyone new to the standard. This white paper gives an overview of some popular HEVC analysers as well as their installation guides, usage and available features. HEVC bitstream analyzers featured include Elecard HEVC analyser, Parabola Explorer and Zond265.

The full whitepaper is available here. If you would like us to feature your analyzer product, please get in touch.
