ITU-R QUESTION 9/6-2003 模拟和数字地面电视广播的通用信号传送器和再传送器.文件6/1-E

The ITU Radiocommunication Assembly considering a) that introduction and implementation of digital terrestrial TV broadcasting should be realized taking account of existing terrestrial broadcasting; b) that digitalization of TV distributional network leads to a radical increase in the number of programs delivered by the network and thus to the need for additional transmitters and retransmitters to be installed; c) that most of additional transmitters and retransmitters are currently being installed for existing terrestrial broadcasting; d) that there are advantages in reuse of currently installed transmitters and retransmitters, i.e. their further use for digital terrestrial TV broadcasting; e) that such reuse is especially important when digital terrestrial TV broadcasting are being implemented not in addition to existing terrestrial TV broadcasting but as their replacement, because of the lack of frequencies; f) that the reuse of currently installed transmitters and retransmitters for digital terrestrial TV broadcasting should be preferably realized with a minimum alteration or no alteration at all; g) that signal transfer into the broadcasting frequency band, amplification and transmission are common function for both analogue transmitters (with amplitude modulated PAL/NTSC/SECAM input signal) and digital transmitters (with multiprogram digital TV signal modulated for digital broadcasting, or HDTV, as input signal); h) that part of the functions of present analogue transmitters and retransmitters – i.e. amplitude modulation of the TV signal and sideband filtering – can be shifted to the digital decoders of the distributional network, which will implement these procedures digitally and with a higher quality by producing amplitude modulated PAL/NTSC/SECAM signals with a partly suppressed sideband and also frequency modulated audio.
