The Range Extensions (RExt) of the High Efficiency
Video Coding (HEVC) standard have recently been approved
by both ITU-T and ISO/IEC. This set of extensions targets
video coding applications in areas including content acquisition,
postproduction, contribution, distribution, archiving, medical
imaging, still imaging, and screen content. In addition to the
functionality of HEVC Version 1, RExt provide support for
monochrome, 4:2:2, and 4:4:4 chroma sampling formats as well
as increased sample bit depths beyond 10 bits per sample.
