Spain has officially confirmed that 5 November 2026 will mark the beginning of a new era for its digital terrestrial television platform, with the launch of DVB-T2 broadcasting and Ultra HD (UHD) services on TDT (Televisión Digital Terrestre).

The move represents the biggest upgrade to Spain’s terrestrial television network since the country’s digital switchover and is designed to improve picture quality while making more efficient use of available broadcast spectrum.

For viewers, the change should bring more free-to-air UHD content, while broadcasters will benefit from the increased efficiency offered by the newer DVB-T2 transmission standard.

What is changing?

Until now, the majority of Spain’s TDT channels have been broadcast using the original DVB-T standard together with H.264 (AVC) video compression.

From 5 November 2026, one national multiplex will transition to the more advanced DVB-T2 transmission system using HEVC (H.265) compression.

This combination allows broadcasters to transmit significantly more data within the same amount of spectrum, making it possible to offer Ultra HD television services without requiring additional frequencies.

The first phase of the rollout will also see the launch of a new national commercial television service known as SIETE, alongside the expansion of UHD broadcasting.

Better picture quality

The biggest benefit for viewers will be improved image quality.

DVB-T2 and HEVC together allow broadcasters to deliver 4K Ultra HD pictures with much greater efficiency than the existing DVB-T platform.

Spain has already demonstrated its commitment to UHD broadcasting by becoming one of Europe’s first countries to launch a permanent free-to-air UHD television channel. The November launch expands that strategy, allowing more viewers to benefit from higher-quality terrestrial broadcasts.

Although UHD content will initially be limited, the long-term objective is for Spain’s terrestrial television platform to become almost entirely DVB-T2 based.

Will viewers need new equipment?

For many households, the transition should be relatively straightforward.

Most televisions purchased over the past several years already include DVB-T2 tuners and support HEVC decoding. In these cases, viewers will simply need to perform a channel retune once the new multiplex begins broadcasting.

Owners of older televisions that only support DVB-T will continue receiving existing HD channels during the transition period. However, they will eventually need either a compatible DVB-T2 receiver or a newer television if they wish to receive future UHD services.

The phased approach is intended to avoid forcing millions of households into replacing perfectly serviceable equipment overnight.

Apartment buildings may require updates

While many individual homes will only need a retune, some communal aerial systems installed in apartment buildings may require technical adjustments.

Older head-end amplifiers and filtered distribution systems may need updating to accommodate the reorganised multiplexes and the introduction of DVB-T2 services.

Professional aerial installers are therefore expected to see increased demand as the migration progresses.

Existing channels continue

The vast majority of Spain’s national television services will remain available throughout the transition.

However, some channels will move between multiplexes, meaning viewers who do not retune their televisions after 5 November could temporarily lose services such as Clan, DKISS, Atreseries, BeMad and Boing until a new channel scan is completed.

For most viewers, this will simply involve running the television’s automatic tuning process.

A gradual migration

Importantly, Spain is not switching off DVB-T immediately.

Instead, the government is adopting a phased migration strategy.

The initial DVB-T2 multiplex launches in November, while the existing DVB-T network remains operational to ensure older receivers continue working.

Only once DVB-T2-compatible receivers are present in the overwhelming majority of Spanish homes will the remaining multiplexes migrate to the newer standard.

This gradual approach minimises disruption while encouraging viewers to upgrade naturally as they replace ageing televisions.

How does Spain compare with the UK?

Spain’s decision places it among the more ambitious European countries when it comes to terrestrial television.

While the UK already uses DVB-T2 for some Freeview HD services, there are currently no plans for a nationwide migration to DVB-T2 or the widespread introduction of UHD terrestrial channels.

Instead, UK broadcasters have focused much of their Ultra HD development on satellite and internet streaming platforms.

Spain, by contrast, continues to invest heavily in free-to-air terrestrial broadcasting, recognising that millions of viewers still rely on TDT as their primary means of receiving television.

Looking ahead

The launch of DVB-T2 and UHD broadcasting on 5 November represents a significant milestone for Spanish television.

Although the transition will take several years to complete, it lays the foundations for a more efficient terrestrial platform capable of delivering higher picture quality and supporting future broadcasting technologies.

For viewers with compatible equipment, the upgrade should be as simple as carrying out a channel retune. For the broadcasting industry, however, it marks the beginning of the next generation of free-to-air television in Spain.
