Trinity Broadcasting Network

==TBN HD==
On December 15, 2009, the Trinity Broadcasting Network became the first Christian television network to broadcast completely in [[High-definition television|high definition]].<ref name="Web Wire.com">{{cite web|title=TBN Launches High Definition Channel on AT&T's U-Verse TV Service|url=http://www.webwire.com/ViewPressRel.asp?aId=111013|work=Webwire.com|date=January 15, 2010|access-date=November 11, 2010}}</ref> However, until 2018 only the national cable-satellite feed was transmitted in HD; TBN's [[owned-and-operated stations|owned-and-operated broadcast stations]] were not equipped to allow HD broadcasts due partly to the bandwidth limitations caused by its mandatory carriage of five subchannels over a single broadcast signal and the lack of a modern [[multiplexer]] at the transmitter level, disallowing TBN's [[master control]] from sending the main feed in high definition or [[widescreen]] [[standard-definition television|standard definition]] (this is in comparison to Ion Media Networks, which carries five to six multiplex services on most of its stations – including its flagship network [[Ion Television]], which is transmitted in high-definition); the primary TBN network feed is transmitted in standard-definition by its owned-and-operated stations and affiliates. Thus, widescreen programming on TBN's broadcast services were offered over-the-air in a [[letterboxing (filming)|letterboxed]] [[4:3]] picture format, though they are offered in their native formats on pay television and IPTV services (including TBN's mobile and [[digital media player]] apps, the latter requiring email authentication and an opt-in to the network's mailing list as of June 2018). At some point in 2018, some TBN over-the-air stations upgraded their primary feed and second subchannel to 720p HD, where available and/or technically possible.
