station's digital signal is multiplexed: On September 26, 2011, KHOU began broadcasting Bounce TV on its second digital subchannel (which originally launched as a quasi-independent station) upon the network's launch. The station had previously signed on to carry the .2 Network on one of its digital subchannels, although .2 Network never debuted. In 2015, the station began carrying programming from the Justice Network on its third digital subchannel. Quest was added to the fourth digital subchannel on January 16, 2018 and was changed to a simulcast of sister station KTBU after that station switched to the network on March 27, 2020; as of April 5, 2021, the fourth digital subchannel is affiliated with Twist. The fifth digital subchannel, Circle, which is 50 percent owned by Gray Television with the other half owned by a subsidiary of Ryman Hospitality Properties' Opry Entertainment Group, debuted with the network on January 1, 2020. Bounce TV moved to KPXB-DT2 in January 2022. Analog-to-digital conversion KHOU discontinued regular programming on its analog signal, over VHF channel 11, on the morning of June 12, 2009, as part of the federally mandated transition from analog to digital television. The station's digital signal relocated from its pre-transition UHF channel 31 to VHF channel 11.
