Definizione
Wikipedia
The class A television service is a system for regulating some low-power television (LPTV) stations in the United States. Class A stations are denoted by the broadcast callsign suffix "-CA" (analog) or "-CD" (digital), although very many analog -CA stations have a digital companion channel that was assigned the -LD suffix used by regular (non-class-A) digital LPTV stations.
The FCC created this category of service as a result of the Community Broadcasters Protection Act of 1999. Support for this ruling came largely from the Community Broadcasters Association, an industry group representing low-power TV station operators.
Unlike traditional LPTV stations, class-A stations were given primary status during the transition to digital television (DTV), meaning that a full-service television station could not displace a class A LPTV station from its broadcast frequency (TV channel), except in rare cases. In contrast, traditional LPTV stations often found their frequencies assigned to full-service DTV operations, forcing them to relocate to another frequency. This was especially true in large cities, where available broadcast spectrum was scarce, and LPTV stations found themselves forced to cease operations due to no suitable spectrum. This was especially so with the taking of the 700 MHz band (channels 52 to 69) from the upper UHF TV band.
