Although the network natively transmits in the 16:9 aspect ratio, KAUT-DT3 transmits Court TV Mystery programming in a horizontally condensed 4:3 format. (As Katz's subchannel-leasing agreements are structured as such that duplicate affiliations exist among some of its networks in certain markets, KAUT-DT3 shares the Court TV Mystery affiliation with KSBI, which began carrying the network—under the former Escape brand—on its DT5 subchannel in October 2018.) 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. Upon the network's debut on May 8, 2019, KAUT launched a subchannel on virtual channel 43.4 (or UHF digital channel 40.4) to serve as an affiliate of Court TV, which aired over the subchannel until it was decommissioned in coincidence with Court TV's relocation to KAUT-DT2 on October 28. The DT4 subchannel was restored six weeks later on December 9, 2019, as an affiliate of the NBCUniversal-owned classic television network Cozi TV. (As of the time of the addition, KAUT-DT4 shares the Cozi TV affiliation with Enid-licensed KBZC-LD [channel 42], which had switched its DT5 subchannel from QVC to Cozi in September 2019.) The station's digital signal is multiplexed: KAUT-TV launched a digital signal on UHF channel 40 in June 2005. The station originally planned to transmit on UHF channel 42 by the May 1, 2002 deadline for full-power television stations to sign on a digital signal; however, the assignment had also been given to then-fellow UPN affiliate KTFO (now KMYT-TV) in Tulsa, which led then-KAUT owner Viacom Television Stations Group to apply to relocate its digital channel assignment to UHF 40 in order to prevent co-channel interference with KTFO's digital feed.
