It operated briefly in 1987, but was shut down after only a few months of operation and its non-commercial educational broadcast construction permit ultimately revoked. History Prior use of channel 68 in Los Angeles Channel 68 was used originally by the Viewer Sponsored Television Foundation as KVST-TV, which broadcast from May 5, 1974, through December 23, 1975. It was a station with a strong community focus and aired alternative programming, much of it leftist in nature. However, it constantly struggled for viewer support and suffered through tumultuous internal politics, leading to its closure.

KVST-TV
KVST-TV was a television station on channel 68 in Los Angeles, California, owned by the Viewer Sponsored Television Foundation. Broadcasting from May 5, 1974, through December 23, 1975, KVST-TV was an early experiment in public-access and community television that struggled to gain enough viewer support to operate. History Viewer Sponsored was formed in 1967 to bid on channel 58, the second non-commercial television allocation for Los Angeles. It lost to the Los Angeles Unified School District, in large part because the group had only raised 25 percent of the $528,000 need to construct and operate the channel; hearing examiner Chester F. Naumowicz found the LAUSD bid on better financial footing. (A third applicant, KCET channel 28, had previously dropped out of the running to avoid lengthy and expensive proceedings.) However, in that proceeding, Viewer Sponsored Television asked for the allocation of channel 68 for noncommercial use in Los Angeles, which was approved by the Fede ...

Ultra High Frequency
Ultra high frequency (UHF) is the ITU designation for radio frequency, radio frequencies in the range between 300 megahertz (MHz) and 3 gigahertz (GHz), also known as the decimetre band as the wavelengths range from one meter to one tenth of a meter (one decimeter). Radio waves with frequencies above the UHF band fall into the super-high frequency (SHF) or microwave frequency range. Lower frequency signals fall into the VHF (very high frequency) or lower bands. UHF radio waves propagate mainly by Line-of-sight propagation, line of sight; they are blocked by hills and large buildings although the transmission through building walls is strong enough for indoor reception. They are used for UHF television broadcasting, television broadcasting, cell phones, satellite communication including GPS, personal radio services including Wi-Fi and Bluetooth, walkie-talkies, cordless phones, satellite phones, and numerous other applications.

DTV Transition In The United States
The digital transition in the United States was the switchover from analog to exclusively digital broadcasting of terrestrial television programming. According to David Rehr, then president and CEO of the National Association of Broadcasters, this transition represented "the most significant advancement of television technology since color TV was introduced." For full-power TV stations, the transition went into effect on June 12, 2009, with stations ending regular programming on their analog signals no later than 11:59 p.m. local time that day. Under the Digital Transition and Public Safety Act of 2005, full-power broadcasting of analog television in the United States was initially planned to have ceased after February 17, 2009. To help U.S. consumers through the conversion, the Act also established a federally sponsored DTV Converter Box Coupon Program. The DTV Delay Act changed the mandatory analog cutoff date to June 12, 2009, although stations were permitted to cease ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
