What Matters What's in the News (1978–2004) The WPSU-TV Alphabet Cooking Show Your Health Technical information Subchannels The station's digital signal is multiplexed: Analog-to-digital conversion WPSU-TV shut down its analog signal on VHF channel 3 on June 12, 2009, the official date on which full-power television stations in the United States transitioned from analog to digital broadcasts under a federal mandate. The station's digital signal remained on its pre-transition UHF channel 15. Through the use of PSIP, digital television receivers display the station's virtual channel as its former VHF analog channel 3. Distributed transmission WPSU-TV is an innovator of distributed transmission of digital television signals; it has been involved with testing new ways to distribute these signals to difficult reception areas and received an experimental permit from the FCC in 2003. Initial tests showed that while a large UHF channel 15 transmitter at the location of WPSU's original low-VHF broadcast tower would encounter localized problems with terrain shielding that interfere with UHF reception in State College, and that relocation of the main transmitter would have interfered with the station's ability to serve the other two communities, the addition of a 50 kW, precisely-synchronized digital transmitter operating in State College itself on the same frequency as the main UHF 15 signal could provide a viable improvement to digital reception. This work was the basis for a pair of ATSC standards issued in 2004 to provide design guidance for the implementation of distributed transmission systems: A/110A, "Synchronization Standard for Distributed Transmission, Revision A" A/111, "Design of Synchronized Multiple Transmitter Networks" These standards were later used by other broadcasters, such as New York City's Metropolitan Television Alliance, as a basis of tests in 2007. This testing was crucial to other U.S. television
