maintaining a standard-definition test simulcast of the station's primary channel. On October 25, 2010, KNVA-DT2 converted into an affiliate of TheCoolTV, as a result of then-parent LIN Media having signed a deal with Cool Music Network LLC to carry the music video network on the group's stations in eleven of the 17 markets where it operated stations at the time; LIN dropped the network from KNVA and its sister stations elsewhere in the U.S. – and decommissioned the 54.2 subchannel – on February 28, 2013. On November 16, 2015, Media General announced that it had reached an agreement with Katz Broadcasting to affiliate 16 stations owned and/or operated by the group — including KNVA — with one or more of three Katz-owned multicast networks, Laff, Escape and Grit. As part of the agreement, on January 29, 2016, KNVA relaunched its DT2 subchannel to serve as an affiliate of Grit. KNVA-DT3 KNVA-DT3 is the Laff-affiliated third digital subchannel of KNVA, broadcasting in standard definition on UHF channel 23.3 (or virtual channel 54.3). On January 29, 2016, as part of Media General's agreement with Katz, KNVA launched a digital subchannel on virtual channel 54.3 to serve as an affiliate of Laff. (Under the initial agreement, the Laff affiliation rights in the Austin market originally intended to be assigned to a subchannel of KBVO.) KNVA-DT4 KNVA-DT4 is the Ion Mystery-affiliated fourth digital subchannel of KNVA, broadcasting in standard definition on UHF channel 23.4 (or virtual channel 54.4). The subchannel is not carried on the market's cable systems as Court TV Mystery already holds local cable carriage rights through its secondary Austin affiliate, Killeen-licensed Univision O&O KAKW-DT (channel 62), which carries the network on its DT4 subchannel. (Katz Broadcasting's affiliation agreements for Court TV Mystery and its sister networks are structured as non-exclusive subchannel leases, resulting in certain Katz networks being carried on more than one station in certain markets such as Austin.) On October 13, 2017, as part of a June 2016 agreement between Nexstar Media Group and Katz Broadcasting to affiliate 81 stations (aside from those covered by the Media General agreement that preceded Nexstar's purchase of the group) with one or more of Katz's four multicast networks, KNVA launched a digital subchannel on virtual channel 54.4 to serve as an affiliate of Escape. The subchannel's branding changed to Court TV Mystery on September 29, 2019. Programming KNVA currently carries the entire
