At the NAB show in Las Vegas, ATEME is debuting its GPAC, an open source implementation of a software media player supporting the HEVC video compression format standardized by the ITU as H.265.GPAC is designed for playback of live or file-based audio and video content, and also to encapsulate and transmit such content as a stream. Those functionalities are now extended to files or streams encoded with HEVC. It has been validated with a 1080p HD content delivery chain. Work is now ongoing to extend the use cases to Ultra HD.The company's TITAN File and Live transcoder with support for HEVC, used in combination with the GPAC player, will be on display at NAB.
