Digital T.V
Post: #1

Broadcasters are concerned with many in-band and out-of-band transmission parameters, including data signal quality, clock tolerance, radiated power tolerance, carrier phase noise, adjacent channel emissions, and precision frequency offset requirements. The FCC permits DTV power-level changes and/or transmitting antenna location and height and beam tilt in the context of de minimise interference levels. The Advanced Television System Committee (ATSC) has provided guidelines for broadcasters in the form of suggested compliance specifications, which will be covered in this paper. On December 24, 1996, the FCC adopted the Advanced Television System Committee (ATSC) system (minus video formats) as the new digital television standard for the U.S. Shortly thereafter, on April 3, 1997, the FCC issued its rules for digital operation as well as its first set of channel allocations, loaning each U.S. broadcaster a second 6 MHz channel for digital television transmission. Subsequently, a revised set of allocations was issued in March 1998 with additional rules and changed rules, including a new transmission emission mask and potential increased transmission power provided new de minimise interference criteria are met. Terrestrial digital (DTV) broadcasting is now underway in the major markets in the United States after the Federal Communications Commission (FCC) in several Reports and Orders set the standard on December 24, 1996, and subsequently released rules of operation and broadcaster channel allocations. DTV broadcasters are mainly concerned about the in band and out of band parameters. The in-band parameters describe the signal quality. The important in-band parameters are spectral shape, data pulse shape, data eye pattern, transmitted power specifications etc. The out of band parameters include rigid TV emission mask, NTSC weighted out of band power, DTV un-weighted out of band power, beam tilt techniques etc.
