TBN HD
On December 15, 2009, TBN became the first Christian television network to broadcast completely in high definition. However, only the national feed on cable and satellite is transmitted in HD, as its owned-and-operated terrestrial stations are currently not equipped for HD broadcast due in part to technical limitations caused by the number of subchannels TBN requires its stations to carry that prevent the main TBN subchannel on its owned-and-operated stations to be carried in high definition or widescreen standard definition.
Programs produced in the widescreen format that are available in high definition on the cable/satellite HD feed are downconverted to 480i SD and broadcast in a letterboxed 4:3 picture format on all five of TBN's U.S. channels carried on the network's over-the-air digital stations.
