​V-Nova Wins Validation from EE

Compression specialist V-NOVA has been racking up the validations for its technology Perseus. IRT, EE, and NTT DATA have all done trials and reported success. This is on top of news that Alcatel Lucent is working to integrate the tech into its systems.

Operator EE has trialled the compression solution to stream 4K over its 4G network. “The trial with V-Nova has proven that smart software like Perseus can make a big difference for mobile network operators managing their long term video strategy,” said Matt Stagg, Head of Video Strategy at EE.

The trial addressed a number of challenges including the transport of UHD/4K content over the mobile network; delivering HD video to tablets and phones while travelling, and; providing reliable video services to rural areas, where mobile bandwidth may be limited.

The test distributed UHD/4K video over EE’s 4G network in a densely populated area of central London, near Paddington station at rush hour. The 4K content – footage from EE’s ‘Wembley Cup’ series – was streamed to a 65” 4K screen at 50fps via the EE ‘Osprey’ 4G WiFi hotspot.

The same content was also delivered in HD to tablets and phones at bitrates ranging from 300 Kbit/s to 1.5 Mbit/s, both on the road and in a rural location in The New Forest, in the south of England.

“A continuous high-quality viewer experience” was claimed to be maintained throughout the 90 mile journey, handing the signal over between more than 40 sites, and at the very edge of the EE 4G network.

Added Stagg, “We have built in a massive amount of capacity to our network because we know that our customers are demanding more and more video – it’s growing at a phenomenal rate. As well as adding more bandwidth, we’re looking at intelligent, cost-effective ways of delivering video more efficiently, and more reliably in challenging environments such as densely populated urban areas and travelling at high speed in a car or on a train.

“Early discussions about Perseus focused primarily on its exceptional compression performance,” said Guido Meardi, V-Nova CEO and co-Founder, “The trial with EE delivers many advantages beyond bitrate reduction— including significantly increased processing speed, lower power consumption, increased robustness, and graceful, block-free degradation at ultra low bitrates.”

German broadcast body IRT (Institut für Rundfunktechnik) has validated V-Nova, saying it has carried out tests of Perseus in contribution applications.

The Munich-based R&D wing for German broadcaster ARD and ZDF evaluated the technology against benchmarks set by JPEG2000 in contribution and production codecs AVC Intra Class 100 and XAVC-Intra 100 at comparable bit-rates. The results, based on a mixture of objective and subjective evaluations, “confirm a substantial improvement compared to JPEG2000 and a quality that challenges H.264-intra-based production codecs”. The tests were performed on HD interlaced content (1080i/25), which represents the large majority of content being acquired today.

“The IRT has always been at the forefront of modern media and the technology innovations needed to move our industry forward. Testing Perseus is important to enable our broadcasting, media, communications-engineering and IT clients to have a quantitative basis to assess the potential of this new technology” said Dr. Rainer Schäfer, General Manager TV, IRT.

Meardi added: “These results, combined with the many other benefits of Perseus, such as Continuous Hierarchical Adaptability translate to large bitrate reductions and the real commercial value that our customers are seeing. We know that the benefits are even larger at higher resolutions such as UHD/4K and higher frame rates such as 1080p50/60.”

In a related announcement, V-Nova said global IT service provider NTT DATA had integrated Perseus into its video encoding solutions. In particular, the compression tech has been added to NTT DATA’s Hyper for automated batch video transcoding and NRT products.

Meardi claimed: “With a simple software update, NTT DATA solutions can now offer OTT and VoD operators a real ‘game changer’, including the ability to extend their service reach by ten times.”

“By integrating Perseus we provide a unique product that is able to assure the best quality and effectiveness for on demand video,” Riccardo Ferrari, senior manager Multimedia Solution NTT DATA Italia said in a statement.
