TV Boxes VHF signal boosters and UHF converters http://www.tv-boxes.com/ Television got its start in the U.S. in the Big Cities.   In the late '40s and early '50s, unless you lived in or near New York City, Philadelphia, Chicago, Los Angeles, or one of the other major population centers, TV reception was likely to be an iffy thing.   There were only about 100 TV stations in the entire US.   People put up big rotatable antennas to capture the weak signals from 50 or 100 miles away, and augmented the tuners in their TV sets with signal boosters. Video Preservation Website http://videopreservation.stanford.edu/ The purpose of this site is to encourage the preservation of historic video using the mature technology of digital capture [video capture cards], to create individual video files, which would be stored on mass storage media such as hard drives (HDD) or data tape (DT). The individual video files created can be copied without loss -- forever. As with all computer equipment, the storage media must replaced when (a) system components begin to fail with age or (b) the technology advances. The digital files would be migrated to new storage with no loss due to recapture, noise, haste, error or budget restrictions.
