How to retune the TV channels after the DTT SD blackout

It’s less than a week until all channels in SD quality disappear from the DTT. These are the first to arrive on the digital terrestrial television grid, offering a resolution then called standard that has long since ceased to be so. Specific, 854 x 480 pixelsthe same one that offered the format DVD and that gave much better results on the old televisions CRT that on current screens where the usual thing is Full HD (1,920×1080 pixels) or higher resolutions. The new standard for DTT will be HDthat is, a resolution of 1,280 x 720 pixels which offers a better viewing experience than SD channels.

What users will find the next day 14 is that the current frequencies of the SD channels will go black and the channels that do not yet have HD broadcasts will begin to broadcast in this format. This is the case of FDF, Divinity, Energy, Boing Neox, Nova, Mega, Ten, Trece, DKISS, Gol Play, DMAX, Disney Channel and Paramount Network.
