Digital TV is an evolution of the utilisation of radio frequencies in which efficiency will be way higher than that of the analogue system. With digitalisation, one frequency transmission can carry as many as eight to 25 channels while the analogue system can carry only one.
But why digitalisation? Firstly, digital TV allows viewers to get more channels with a greater variety of content such as news, children’s shows and more programming compared with the existing six free-analogue TV channels (channels 3, 5, 7, 9, 11 and Thai PBS) and this also includes cable and satellite. Digital TV broadcasters are expected to produce a higher quality and greater variety of content.
Moreover, the quality of sound and images will be improved with the digitalised platform with a reduction in interference.
