WCBS-TV
On October 21, 2014, CBS and Weigel Broadcasting announced the launch of a new digital subchannel service called Decades, scheduled to launch on all CBS-owned stations on May 25, 2015, including on WCBS-TV on channel 2.2. The channel is co-owned by CBS and Weigel (owner of CBS affiliate WDJT-TV in Milwaukee), with Weigel being responsible for distribution to non-CBS-owned stations. It airs programs from the extensive library of CBS Television Distribution, including archival footage from CBS News. On September 3, 2018, Decades was replaced on 2.2 by Start TV.
Milwaukee PBS
WMVS broadcasts its digital signal on VHF channel 8, and WMVT broadcasts on UHF channel 35; the stations respectively map to their respective former analog channel allocations via PSIP, 10 and 36. All of the digital subchannels mentioned below broadcast 24 hours a day, seven days a week. Until September 1, 2010, WMVS provided its main channel feed in 1080i HD, while WMVT's digital channel was used for multicasting in 480i standard definition. However, with the complexities of the digital transition causing viewers to be unable to receive WMVS's VHF over-the-air signal – as has been a major problem in other markets – the Milwaukee PBS stations re-mapped their digital channels on September 1, 2010 in order to maximize their services, and to prepare for WMVT's 36.1 channel to eventually be transmitted in high definition in response to viewer demand. The main 10.1 signal was also reduced to 720p, as opposed to PBS's preferred 1080i format.
