If the digital transition hadn't happened I think over the air television might have died by now. Analog broadcast used significantly more electricity and fewer and fewer people would be interested in the low quality signal. Stations might have decided the remaining viewers weren't worth the power cost.
That said I think streaming might kill it anyway.
- generatorguy 6y agoCan you quantify the difference in electricity costs? Start with difference in Watts, guess 0.15$/kWh and then find $/year saved? I bet the increase in quality and maybe the reliability or support costs for the old analog equipment were bigger factors.
- Dylan16807 6y ago...so how much would it have improved the reception if they kept using the same amount of power for digital?
- toast0 6y agoWhat's the difference in power for analog vs digital TV broadcast?? Is that mostly because ATSC broadcasts moved towards UHF, and NTSC broadcasters preferred VHF when available? Or is there some other property of ATSC broadcasts that require lower energy?
- LeoPanthera 6y agoAnalogue video has to have a very high SNR at the receiver, because any noise is directly visible in the picture. But with a digital signal, as long as you can distinguish individual bits, the picture is always perfect, so you can get away with a much lower signal strength.
