The Transition to DTV
In the United States, the FCC's DTV rollout schedule set deadlines for stations to complete the DTV transition process. Commercial television stations were supposed to have completed construction of DTV facilities by May 1, 2002. Public television stations were supposed to have completed their DTV facilities by May 1, 2003. Of course, extensions were granted based on individual circumstances. Once a station is DTV ready, that station may broadcast DTV programming. The FCC's schedule for transition to DTV originally proposed that everyone in the U.S. should have access to DTV by 2002, although analog transmissions continued after that date. After the switch to digital has been completed, regular television sets will need converters to receive broadcasts, although their sets will remain functional indefinitely. Actions are being taken to make the transition as smooth as possible. For example, in the Telecommunications Act of 1996, the FCC allotted to each existing broadcaster an additional 6MHz channel for digital transmissions, so that they could send out both analog and digital transmissions simultaneously. This procedure is known as simulcasting. The FCC mandated that all analog transmission would cease in 2009.
