The joint patent holders of the technology have demanded licence fees which many in the industry consider either too high or too vague to justify investment. However, HEVC has not taken off in the same way previous standards have because MPEG was not alone in its development. MPEG-4 cut the bandwidth needed to deliver programming by half, and its successor H.265/HEVC (High Efficiency Video Coding) published in 2013 managed the same 50% saving trick again. MPEG-2 was the de-facto format of digital TV signals before MPEG delivered a more efficient scheme, MPEG-4/ H.264 AVC, in 2004. Video compression has been dominated for as long as anyone can remember by standards bodies Motion Picture Experts Group (MPEG) and ISO/IEC. That’s changing as the current market leader, HEVC, is challenged by a new generation of codecs potentially capable of delivering improved video playback at greater efficiency and crucially, at lower cost.
