KPBS (channel 15) is aPBS membertelevision station inSan Diego, California, United States. Owned bySan Diego State University (SDSU) as part ofKPBS Public Media, it is asister station toNPR memberKPBS-FM (89.5). The two outlets share studios at the Conrad Prebys Media Complex at Copley Center on Campanile Drive on the SDSU campus.[2] The TV station's transmitter is located onSan Miguel Mountain in southwesternSan Diego County.

History

[edit]

In 1960, San Diego State College (now San Diego State University) applied for alicense from theFederal Communications Commission (FCC) to operate anon-commercial educational television station to serve San Diego. The station first signed on the air on June 12, 1967, as KEBS-TV.[3] The station was originally a member ofNational Educational Television (NET) before becoming a member of PBS when it launched in October 1970, at which time the station changed its call letters to KPBS-TV.[4] Despite the calls, which mimic the callsign schemes used by stations owned byABC,NBC, andCBS in New York City and Los Angeles, it is not anowned-and-operated station (nor is similarly-namedWPBS inWatertown, New York), as PBS cannot own or operate any of its member stations or regional member networks due to the service's local and non-profit nature. The KPBS call sign reflects the station's affiliation and programming, but not any special status within PBS.

KPBS started broadcasting digital television on November 21, 2001.[5] On June 12, 2009, the station turned off its analog signal overUHF channel 15 in accordance with the federal mandate fortransitioning television broadcast from analog to digital. The station's digital signal remained on its pre-transition UHF channel 30.[6][7]

On January 1, 2011, when Los Angeles' longtime PBS stationKCET ended its membership, KPBS began to be carried on cable providers in theBakersfield market, alongside fellow PBS stationsKVCR-DT inSan Bernardino andKVPT inFresno. It is also one of three PBS member stations that serve thePalm Springs market, alongside KVCR-DT andKOCE-TV inHuntington Beach (which succeeded KCET as Los Angeles' primary PBS member station).

By the middle of the 2010s, KPBS experienced budgetary constraints and erosion of viewership. The locally produced current affairs showFull Focus attracted less than one percent of the potential audience. One of the ways to increase viewership was to increase the number of subchannels as other public TV stations had done.[8]

On March 26, 2019, the digital signal has been moved to UHF channel 19 as a result ofspectrum reallocation.[9]

News programming

[edit]

KPBS produces a nightly half-hour news program on weeknights titledKPBS Evening Edition, a self-contained television newscast that is an extension of theMidday Edition newscast aired by its radio sister. KPBS' news department is editorially independent from the station's management, San Diego State University and corporate underwriters and donors. The station's investigative reports are conducted in collaboration with the nonprofit newsgathering organization Investigative Newsource, which shares a newsroom with KPBS television and radio at the Campanile Drive studios.

The station collaborates on breaking news coverage and shares news video with the localABC affiliateKGTV (channel 10).

Subchannels

[edit]

The station's signal ismultiplexed:

The initial lineup consisted of two multiplexed channels: the main high definition channel in 720p and the standard definition channel in 480i, the latter used for DTV simulcast of analog channel 15.[5][11] In 2006, an SD sub-channel was added, carrying content fromCreate.[12] That same year, the main HD channel was switched from 720p to 1080i.[11] Later that year, KPBS dropped the simulcast of analog channel 15 and implemented statistical multiplexing.[13]

In 2007, KPBS replaced Create withV-me, a 24/7Spanish-language public television channel.[14]

In January 2017, V-me ended its multicast service for public television, transitioning to commercial cable. KPBS, along with many other PBS affiliates, replaced V-me with thePBS Kids multicast channel.[15] KPBS relaunched Create subchannel and added one more subchannel, KPBS2. John Decker, director of programming at KPBS in San Diego, explained that multicasts such as PBS Kids, Create, World, and locally developed programming "give public TV an opportunity to increase value and thus loyalty among viewers" as well as "allow KPBS to expand its universe".[16]

Simultaneously with the 2017 lineup change, KPBS switched its HD format from 1080i to 720p and changed aspect ratio of SD channels from 4:3 to 16:9. Image quality degradation, caused by sharing of available bandwidth over four multiplexed channels, was noticed by viewers.[17]
