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.

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.
Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...
Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...
A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.
Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...
In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.
“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...
The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.
The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
