agreement with Katz Broadcasting that saw 19 other former Tribune stations (including three that were spun off to either the E. W. Scripps Company or Tegna) also dropping This TV in favor of the Katz-owned network, KAUT-DT2 became an affiliate of Court TV. (As a result, This TV does not have an over-the-air affiliate in the Oklahoma City market.) Although the network natively transmits in the 16:9 aspect ratio, KAUT-DT2 (as KAUT-DT4 had done beforehand) transmits Court TV programming in a horizontally condensed 4:3 format. KAUT-DT3 KAUT-DT3 is the Ion Mystery-affiliated third digital subchannel of KAUT-TV, broadcasting in standard definition on UHF digital channel 40.3 (or virtual channel 43.3 via PSIP). The subchannel is not currently available on Cox Communications in the Oklahoma City area or on other cable providers throughout the market. On November 16, 2015, Katz Broadcasting announced it had signed an agreement with Tribune Media to carry Escape (renamed Court TV Mystery in September 2019) on stations owned by the group in four markets.

KAUT-DT4 KAUT-DT4 is the Cozi TV-affiliated fourth digital subchannel of KAUT-TV, broadcasting in standard definition on UHF digital channel 40.4 (or virtual channel 43.4 via PSIP). The subchannel is not currently available on Cox Communications in the Oklahoma City area or on other cable providers throughout the market. On December 10, 2018, as part of the announcement of the network's relaunch, Katz Broadcasting announced it had signed an agreement with Tribune Media to carry Court TV (a multicast network developed by Katz as a revival of the branding and original legal proceedings/true crime format utilized by the present-day comedic reality-focused cable network TruTV from July 1991 until January 2008) on stations owned or operated by the group in 22 markets.
