Digital Terrestrial Television (TDT, for its acronym) is the transmission of images and sounds through binary coding that occurs through terrestrial transmitters.
In Spain, DTT was responsible for replacing Analog Terrestrial Television on April 3, 2010, but less than a month later, a DTT blackout will happen in our country. Next February, DTT will only transmit in HD after the change proposed by the Ministry for Digital Transformation during the pandemic.
We explain what a blackout consists of and how it affects your television.
What about blackouts?
The DTT blackout is a measure that seeks to improve the image quality of channels that broadcast content via DTT. .
This measure means that all channels, if they want to continue being available on DTT, must update their quality to avoid losing it.
The next is February 14, 2024. That is the exact date of the DTT blackout; therefore, all channels that broadcast quality below HD will stop working and will not be tuned. After this date, channels that want to show DTT again must broadcast at a minimum HD quality of 720p.
How will this affect new televisions?
Let’s get to the important stuff. To continue watching television, it is important to consider each of the following elements, because the television must be ready to receive channels with the quality indicated by the BOE (HD quality).
Get an HD-compatible TV: We need to check that our television is compatible with high definition. Usually, this is not a problem. However, for older devices, the option is to buy a decoder with HD capability or a new, more modern television.
Decoder or DTT HD tuner: This device is necessary to connect older televisions that do not have an HD option.
DTT antenna: To receive the DTT signal correctly, it is necessary to have the most appropriate signal and that it be in good condition.
Quality cables: The cables to connect the television antenna or decoder must be of good quality in order to avoid interference in the future.
Settings and channel search: It is also necessary to perform a channel search on the television or decoder, which will allow you to tune and save available DTT channels.
