The launch of the biggest TV boom in history, the digital terrestrial services that form the platform for the phenomenally successful Freeview, was made possible thanks to a grant of 6.45 million euros from the EU’s Framework Programme.
The VALIDATE (Verification and Launch of Integrated Digital Advanced Television in Europe) project, technically underpinned by a BBC-led partnership, gave the UK the technical confidence to launch digital terrestrial TV in 1998. This technical expertise allowed the BBC to solve subsequent technical problems – providing robust signal quality for the 2002 launch of Freeview, offering 30 TV and 20 radio stations without subscription, to 75% of British households. With more than four million boxes being sold in the first 18 months, Freeview became the world’s fastest-selling consumer technology.
The BBC had wanted to offer licence payers the benefits of digital TV for some time. They made the first digital terrestrial television (DTT) broadcast based on a newly agreed DTT standard in April 1996 – 70 years after television was invented. But they needed evidence to prove that the technical standards were adequate, so BBC Research & Development (R&D) agreed to take the lead in VALIDATE.

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event
On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...
Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.
Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....
Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).
When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
Using a new cooling technique MPQ scientists succeed at observing collisions in a dense beam of cold and slow dipolar molecules.
How do chemical reactions proceed at extremely low temperatures? The answer requires the investigation of molecular samples that are cold, dense, and slow at...
Scientists from the Max Planck Institute of Quantum Optics, using high precision laser spectroscopy of atomic hydrogen, confirm the surprisingly small value of the proton radius determined from muonic hydrogen.
It was one of the breakthroughs of the year 2010: Laser spectroscopy of muonic hydrogen resulted in a value for the proton charge radius that was significantly...
