In areas not covered by terrestrial transmissions, the digital channels are provided by the free-to-view VAST satellite platform. The television channels on this platform are all encoded in H.264 and subject to a MPEG-LA controlled transmission patent licensing tax which is included in the VAST broadcaster cost and varies on viewership figures. The terrestrial transmissions still use H.262, which doesn't incur any additional transmission costs, but select channels are broadcast terrestrially in H.264.
