The channel was broadcast at a display resolution of 1440 by 1080i, which despite being less than the usual 1920 by 1080 resolution used for HD broadcasts was still acceptable to the European Broadcasting Union (EBU) of which the BBC is a member. But after years of pressure from bloggers and tech experts alike, the BBC finally relented and switched BBC HD to full 1920 resolution for all broadcasts, not just when 3D was being broadcast. The channel encoded in H.264/MPEG-4 AVC for satellite and terrestrial broadcasts and in MPEG-2 for cable transmissions.
