UK broadcasters join forces in DTT high definition trial
MUMBAI: UK broadcasters BBC, ITV, Channel 4 and Five have joined forces to launch the UK’s first high definition (HD) trial broadcasts to terrestrial aerials.
A specially selected 450-strong audience sample have collected their trial HD set top boxes (STBs) for the closed technical digital terrestrial television (DTT) technical trial, which is due to last six months.
HD, the parties state, is a step change in television technology, which provides far clearer and more detailed pictures than normal standard definition TV. Each picture contains up to five times as much digital information as an ordinary TV picture.
The trial will offer participating broadcasters and their technical partners valuable lessons about delivering HD broadcasts on a digital terrestrial network and also research how the audience enjoys this new format.
It will help to discover whether there could be HD broadcasts on Freeview in future. The trial is being conducted under an Ofcom licence, which strictly limits the number of receivers and forbids reception of the trial stream by general members of the public. Humax and Advanced Digital Broadcast (ADB) have supplied the HD set top boxes for the trial.
The DTT HD trial consists of low power transmissions from Crystal Palace in London on frequencies that are not suitable for high power broadcasting.
National Grid Wireless (NGW) is transmitting the BBC’s HD stream, which went on air last month, and Red Bee Media provides play-out services.
Arqiva is transmitting the multiplex shared by ITV, Channel 4 and Five, with Grass Valley, a business within Thomson, providing broadcast playout and video encoding equipment.
Siemens Business Services is providing technical support for the BBC’s HD trial. The test broadcasts will use MPEG4 video coding, 8K carriers and 64QAM modulation at launch – different parameters may be tested during the trial period.
The BBC’s trial DTT HD stream will offer identical programming to its HD trial broadcasts on satellite and cable over the trial period.
That includes the BBC’s World Cup coverage, major Wimbledon matches and programming highlights such as Planet Earth and Bleak House.
ITV will offer its own World Cup coverage in HD, completing the full line-up of World Cup games, as well as drama such as Agatha Christie’s Poirot specials Death on the Nile and Murder in Mesopotamia, documentaries such as Jean-Michel Cousteau’s Ocean Adventures and classic films including All Quiet on the Western Front and The Big Sleep.
Channel 4’s HD trial broadcasts will include hit US drama series Lost and Desperate Housewives, FilmFour films and other Channel 4 programming.
Five will be showing episodes of CSI in addition to commissioned programmes such as Tim Marlow at MOMA and movies like Cocktail.
Research company TNS Media is conducting the research. The audience panel was selected from online volunteers who registered on a website in April. All had existing HD Ready television sets and will be supplied with special DTT HD set top boxes.

WITT Summit 2026 concludes in New Delhi
Babar Azam’s comical diving attempt goes viral as league introduces anti-dew measures.
MUMBAI: The WITT Summit just wrapped up with enough big ideas to fill a policy playbook because when India’s leaders, thinkers and icons gather under one roof, even the conversations hit sixes. The eighth edition of TV9 Network’s flagship What India Thinks Today (WITT) Summit 2026 concluded on Saturday after two days of dynamic discussions at its New Delhi venue. India’s largest multi-domain public policy and culture summit brought together political leaders, policymakers, sports icons, artists and technology innovators to examine the forces shaping contemporary India and its global standing.
Prime minister Narendra Modi delivered the keynote address on the theme “India and the World” for the third consecutive year. In a wide-ranging speech, he addressed the ongoing conflict in West Asia, calling for restraint and compassion while highlighting India’s continued development trajectory despite global turmoil.
The summit featured candid conversations with state leaders. Telangana Chief Minister A. Revanth Reddy articulated a people-first governance model and contrasted it with other development approaches. Madhya Pradesh Chief Minister Mohan Yadav declared that Left-wing extremism had been effectively eliminated in his state and highlighted preparations for the upcoming Kumbh Mela. Punjab Chief Minister Bhagwant Mann defended his government’s record, citing the closure of 19 toll plazas and creation of the Sadak Suraksha Force. Karnataka Deputy Chief Minister D.K. Shivakumar expressed confidence in Congress prospects in Assam and addressed recent allegations against him.
On geopolitics and national security, Union Minister Jyotiraditya Scindia outlined India’s ambition to become a builder of trusted digital infrastructure for the world, citing the rapid 5G rollout and village-level 4G connectivity.
Cricket received significant attention. Former India captain Sourav Ganguly praised player freedom and trust as hallmarks of great leadership and named MS Dhoni as the greatest captain due to his World Cup successes. India women’s team bowling coach Aavishkar Salvi credited the BCCI and Women’s Premier League for building a pipeline of world-class talent behind the team’s recent ODI World Cup triumph.
The summit also hosted the inaugural AI² Awards 2026, celebrating the convergence of human creativity and machine intelligence in storytelling and content creation. Poet and kathavachak Kumar Vishwas delivered a nuanced take on India’s concept of Dharma and criticised the recent arrest of an 80-year-old Shankaracharya. Veteran lyricist Sameer Anjaan and storyteller Neelesh Misra reflected on changing music trends and artistic responsibility in the wake of a recent controversy involving Nora Fatehi.
In a country where conversations often run as deep as the Ganges, the WITT Summit proved once again that when leaders, thinkers and storytellers come together, the real winner is public discourse lively, layered and refreshingly unafraid to tackle the big questions shaping India’s tomorrow.
