ATV systems aspects and planning factors : investigation report / by Gérald Chouinard, Donald MacMillan, André Vincent, René Voyer.: Co24-3/8-1992-3E-PDF

"Following a request by the Broadcasting Regulation Branch of DOC, an investigation of the systems aspects of the proposed digital advanced television (ATV) simulcast systems was undertaken during the second quarter of 1992 in view of establishing the values of the critical parameters for planning purposes. The results of a detailed review of the ATV systems parameters is presented with an interpretation of the parameter values for planning purposes. The parameters of a typical ATV receiving installation are identified and linked analytically to establish (with more accuracy than in the case of NTSC) a reference ATV receiver model to be used for the planning of ATV broadcasting services. A fully flexible Lotus-123 spreadsheet has been created which ties all the key system parameters together in order to allow for a complete trade-off analysis among all the related system parameters in view of establishing optimum co-channel separations between ATV and NTSC transmitters. Finally, a list of assumptions that will have to be made to allow the planning of the service is tentatively established, hi this case, resulting in more questions than answers"--Introduction, page 2.
