MPEG-HEVC H.265

MPEG High Efficiency Video Coding was developed to achieve twice the efficiency of MPEG-4 AVC. Apart from having the potential to halve the bandwidth currently used to transmit HDTV services, it also halves the data needed to be transmitted for UHD. That means that a 4K UHD channel can fit into one DVB-T2 multiplex – the bandwidth that was used for one analog PAL TV channel.

Beyond helping to enable terrestrial, satellite and cable 4K transmissions, it is also a part of the Ultra HD Blu-ray specification.
