The changes in Digital Terrestrial Television (DTT) in Spain are underway and in 2025 one of the most important reforms of the television broadcasting system is taking place. The incorporation of the 4K resolution (Ultra High Definition) It marks a before and after in the image quality that Spaniards will be able to enjoy in their homes, but it also entails some technical steps that users must keep in mind to avoid being left behind.
On one hand, the new National Technical Plan establishes the foundations for progressively migrating to technology DVB-T2, a standard that allows for higher quality broadcasting and greater efficiency with the available spectrum. In addition, a new tender will be launched to expand the offering with an additional state channel, allowing for more content without resorting to private platforms. For more information on the new 4K DTT channels, you can consult this link.
A two-phase technical transition
The evolution towards UHD will be carried out in stages. In the Phase, which has already begun this year, the current digital multiples have been reorganized to enable the broadcasting of new channels in 4K, without eliminating existing ones. Some of these new channels are already operational, while others will be soon. This stage does not imply a blackout or leave anyone without signal, although it does require retune the television to pick up the new channels.
For this, it is essential that the television is ready to receive a signal under the DVB-T2 standard and be able to decode video in H.265/HEVC formatMany modern models already incorporate it, especially those purchased after 2017, but it's a good idea to check the model's technical specifications or consult the manufacturer.
La second phase —with no specific date yet— will mean that all broadcasts will be made exclusively in UHD and under DVB-T2, which will mean the definitive end of conventional high definition signals. This step will only be taken when at least 95% of televisions in Spain are compatible with new technology to avoid leaving any household out.
Currently, 67,8% of receivers are already prepared for DVB-T2., while 36,6% are ready to broadcast in UHD with the HEVC codec, which still leaves room before activating the full change.
Which channels already broadcast in UHD and which ones will?
The public channel RTVE It was the first to implement UHD broadcasting with its channel La 1 UHD, followed by La 2 UHD. Now, the spectrum is expanded with four new additional channels, of which two are destined for RTVE and the other two for Mediaset y AtresmediaThis will allow channels such as Telecinco y Antena 3 also offer content in 4K.
At the regional level, the case of the Galician Television (TVG), which has become the first regional station to officially broadcast in UHD after successfully passing a trial period. In addition, the system has been activated HDR (High Dynamic Range) to optimize image quality in contrast and color. TVG simultaneously maintains its HD broadcast, allowing you to continue enjoying its programming even if you don't have a 4K TV.
What do I need to do to watch the new channels?
The only action that users need to take for now is retune your TV. Changes in the radio spectrum do not require any modification of the antenna, nor if it is community nor if it is individually. Simply, when the channels start broadcasting in 4K, you will need to scan the frequencies again from the TV menu or from the DTT adapter to detect them.

If your TV is not compatible with DVB-T2, there is always the option of purchasing a external decoder compatible, which is widely available on the market with prices that can start from 15 Euros. Of course, although this will allow you to see the new channels, in some cases you will not enjoy the highest quality, depending on the characteristics of the device.
In case you have a Smart TV receiver, most allow the automatic retune, although it's a good idea to check if it detected all the new channels or repeat the search manually if not. It's important to consider the offers available on platforms such as Amazon to acquire devices that meet the necessary specifications.
Awarding of the new state channel
Another of the most relevant aspects of the new Technical Plan is the future incorporation of a new state-level channelThe Ministry of Digital Transformation confirmed that the The license will be put out to tender before the summer of 2025, with a view to being awarded between autumn and winter of the same year. This opens the door to new information and entertainment offerings that will enrich the current DTT offering.
Although no information has been released on what type of content this new channel will host, its creation seeks to further diversify the television schedule and bring audiovisual services up to date with current technological and consumer demands. If the process is expedited, its broadcast could even begin. before the end of 2025.
The public tender will require interested parties to integrate 4K technology, with UHD broadcasts from the outset, in compliance with the new technical plan guidelines.
Device Compatibility: Are You Ready?
A crucial point in this process is knowing if your television or receiver is ready for this new stage. If you bought a television from 2017, it's most likely compatible with DVB-T2 and H.265. However, it's a good idea to check the product's spec sheet, whether in the manual, on the box, or in the manufacturer's online documentation.
The progressive increase in compatible receivers is one of the keys to the plan continuing its course, and that is why they have been introduced new regulations for manufacturersFrom now on, all televisions of 40 inches or more sold in Spain must include a mandatory UHD tuner, and for models between 24 and 39 inches this measure will be applied with a one-year margin.
In parallel, the possibility of implementing measures to encourage the replacement of older televisions, such as possible subsidies or tax breaks, is being evaluated, although there is no official confirmation on this at this time.
The arrival of these new channels, accompanied by retuning and technical adjustments, marks a turning point in the way we watch television. It's a good idea do your homework so that, when the time comes, everything runs smoothly.
