2 Tutorial on the Grand Alliance HDTV System Background on USA HDTV Why there is a Grand Alliance Basic Grand Alliance HDTV System specifications Tutorial using block diagrams of Grand Alliance HDTV System Issues for FCC Field Operations Bureau 27 July
3 Background on USA HDTV ATSC formed in 1982 FCC Advisory Committee on Advanced Television Service formed in 1987 Over 20 proposals for ATV broadcasting First digital HDTV proposal in 1990 Field narrowed to four digital HDTV and one analog HDTV proposals Proposals tested during 1991 and July
4 No Single Winner from Testing Four digital HDTV systems were found superior to the analog system Each digital HDTV system had some superior characteristics No one digital HDTV system was considered to have overall superiority 27 July
5 Why There Is a Grand Alliance The Advisory Committee suggested the four digital HDTV proponents get together in a Grand Alliance combining the best parts of each system. On May 24, 1993 the Digital HDTV Grand Alliance was formed. 27 July

22 FCC Field Operations Bureau Issues Co-channel and adjacent channel interference into NTSC will increase slightly. The visual effect will be the same as if the signal got weaker more snow. Interference into digital HDTV will not affect pictures and sound, but it will cause the digital HDTV threshold signal level to increase. This is true for co-channel interference, adjacent channel interference, electrical interference, ghosts, etc. 27 July
23 FOB Issues (continued) Propagation effects will be the same as they are for NTSC (for example, inversion layers). People who buy HDTV will pay more money; they will put up good antennas; and they will expect fast resolution of interference problems. 27 July
24 FOB Issues (concluded) Anticipate Advisory Committee recommendation to FCC in Spring Anticipate FCC Rules by end of Anticipate some digital HDTV on-the-air in TV monitoring equipment in trucks and in field offices will need to be in place. So, budget now! 27 July
