Football On January 31, 2019, NFL Network signed a multi-year deal to air Alliance of American Football games, broadcasting two games per week, most of them on Saturday and Sunday nights. As with all other AAF games, the broadcasts were produced in conjunction with CBS Sports. The league ultimately folded in the middle of its inaugural season. High definition NFL Network HD is a 1080i high definition simulcast feed of NFL Network that launched in August 2004. It is available nationally on satellite providers DirecTV and Dish Network, and regionally on Verizon FiOS, AT&T U-verse and most Comcast and Cogeco Cable systems. In mid-October 2008, in-studio programs began to air in "enhanced HD", featuring contained additional scores and statistics on a dedicated wing on the right side of the screen that was only visible on the HD feed. Content that is presented in 4:3 standard definition is shown with stylized pillarboxes, or for some footage, blurred pillarbox wings. On May 1, 2009, NFL Total Access began airing in full HD without pillarboxing or enhanced graphics; this was followed by the upgrade of NFL GameDay to HD the following September. Most providers began to exclusively carry the HD feed of the network during 2011, transmitting a downscaled and letterboxed version of the HD feed to provide the channel in 4:3 standard definition for analog viewers without any deviation, including the "NFL HD" logo. The standard definition feed was discontinued entirely in July 2012, concurrent with the introduction of the network's current logo. NFL RedZone channel The NFL RedZone channel is a special game-day only channel that broadcasts on Sundays during the regular season from 1:00 to 8:00 p.m. Eastern Time (10:00 a.m. to 5:00 p.m. Pacific Time). RedZone provides "whip around" coverage of all Sunday afternoon games airing in-progress on CBS and Fox. Whenever a team enters the red zone, the coverage will switch full-screen over to the live feed of that game's television broadcast, and attempt to cover a potential scoring result (touchdown or field goal). The coverage is hosted by Scott Hanson. This is not to be confused with the completely separate and different Red Zone channel available only on NFL Sunday Ticket. Starting in 2016 NFL Network during the offseason replayed one week of NFL RedZone every Sunday from the previous season.
