The application of the latest National Technical Plan for Digital Terrestrial Television (DTT) has brought with it a new ‘blackout’ in the televisions of thousands of homes in the 75 geographical areas established. The next day, October 14, the last of the steps that have been taking place in the process of the Second Digital Dividend will take place. The cessation of emissions is taking place gradually during this month of October, although initially the final change was scheduled to take place on June 30 . One more consequence of the health crisis caused by the coronavirus.
As a result of the changes, in many houses they have stopped seeing some or many channels, since these have changed the frequency in which they broadcast, so it is necessary to retune the television or the DTT receiver to see them again. Although each television manufacturer is different, the steps to follow to regain access to lost channels are practically the same for each brand.
First of all you have to look for the main menu of the television and from there access the configuration area , although in some televisions there are options for direct access to these settings. Once in the system configuration menu, look for the Installation or Channel Tuning setting(similar words are probably used on your TV), access it and locate the automatic tuning option.Although there are systems that incorporate manual channel tuning, it is not advisable if you do not have much experience in handling the device (and also some time, because the process is slower).
Once the pertinent warnings have been accepted in the tuning menu, the television will begin to search for the channels in their new frequencies and, after a while, all the broadcasts will be able to be seen again.
If one is a little tidy, then the next and always tedious step will remain: order the channels to suit each one.To do this, in the same tuning options there must be a menu in which the channel number that we want to assign to each television can be manually configured.
With this Second Digital Dividend, the frequencies assigned to television channels in the 700 MHz band will be released so that they can be used in the deployment of 5G networks , the fifth generation of wireless communication technologies and standards – which will succeed 4G in force – the Internet used by devices such as our mobile phone to allow us to connect to the network anywhere in the world.
