ITU-R QUESTION 105/6-1999 电视广播的频谱需求

The ITU Radiocommunication Assembly considering a) that terrestrial television broadcasting has commenced the transition from analogue to digital emission; b) that digital technology provides for greater total information capacity than analogue within a given bandwidth; c) that digital emission formats have different protection requirements to those determined for analogue emission; d) that digital emission can provide opportunities for new forms of broadcasting; e) that there is considerable interest in maximizing the efficient use of the spectrum in the VHF and UHF bands; f) that during the transition from analogue to digital which may take 10-15 years those television (“taboo”) channels will be used which are not presently utilized in given areas because of analogue planning constraints; g) that during the transition, resort to the use of the “taboo” channels as described in f) may not be sufficient to provide the amount of spectrum required to implement full digital duplication of the analogue television services.
