The ‘Beyond HDTV’ demonstration on the EBU exhibit has been set up to serve several purposes, starting with a clarification of what 4K means to cinema (4096x2160) and to television (3840x2160).
The serious element starts with Ultra Hi Def in 50p, and the application of HEVC video coding at various bitrates. “It is an experimental
environment, “ said Hans Hoffmann, head of media fundamentals and production at the EBU. “4K displays for
the home will carry a premium, but market take up of 15% will be the point when broadcasters get nervous. The question is, will the premium channels jump on it? And does High Def as it is look competitive enough now?” The EBU is providing test sequences (4K 50p) and will provide stereoscopic
sequences in 1080 50p per eye and at some exceptionally high frame rates – 100Hz and 120Hz. This is to allow EBU
members to perform scientific tests on potential formats. “For broadcasters it is absolutely clear there is no more space available for any

future formats. Whatever they want to do it has to fit in the space we have today for
HDTV,” said Hoffmann. “We can show 4K at 50p with HEVC video encoding in exactly the same bitrates as we use today for HDTV. And it is up to the audiences here to make a decision whether the images are remarkably good of whether they see artifacts.” Is this the picture quality consumers can expect in the home? “Artifacts are very typical for compression,” said Hoffmann. “We of course have certain artifacts at given bit rates, and on critical sequences less artifacts. As we increase the bitrates, the artifacts disappear.” 10.F20
Social media will not spike ratings

Arri By David Fox
A range of ‘ready to shoot’ kits has been launched by Arri for Blackmagic Design’s new Cinema Camera. Starting at $1,200, all the kits include Arri’s mini base plate MBP-3, an ergonomic camera cage system for mounting accessories, and a universal cable safe system CCS-1, which protects internal electronics against accidental stress. A basic configuration adds an aluminium left side support arm CSL-1, providing solid support for handles and accessories, while still allowing for the use of handgrip and controls,
while the top-of-the-line configuration comes with a hot shoe bracket CHS-1 to prevent camera body flex. “The idea behind our Pro Camera Accessories range is to make film-style functionality available to users of all professional cameras that are real players in the market, which the new Blackmagic camera clearly is,” said Stephan Schenk, general manager of Arri’s Camera and DI Business Unit. “Both Blackmagic and Arri have responded quickly to customer demand, working together to create an accessory kit that improves the interface between camera and operator.” 11.F21
Broadcasters may be in danger of overestimating the power of social media as a ratings driver, according to a study from ratings powerhouse GfK. The research reveals more people are likely to watch TV content after catching a TV promo than they are through a recommendation by a friend on Facebook.
GfK teamed up with Red Bee to examine the way viewers watch television by using the VoD specialist’s TV Genius Content Discovery platform, which builds personalised TV listings and recommendations for viewers. Based on a sample of the top shows that aired on UK terrestrial broadcaster ITV, the research indicated that online sources played only a minor role in driving audiences to some of the most- watched-shows on TV. The most important factor for viewers was that it is a regular show that they have seen before. Promos on TV, TV listings and reviews were also key influencers.

Abakus By David Fox
The new Abakus XL borescope/periscope lens system is designed for model work and/or close-up special effects. It can be used directly, straight through, as a
borescope, or as a periscope with a 90º or 45º bend. “High quality has been achieved throughout the system using a new optical telocentric design, which removes the need for field lenses and thus gives a much enhanced quality in the overall performance,” said Abakus MD Dr Ken Pollitt.

Nick North: “We must put social media in context”
global head of Innovation, Audience Measurement, said: “Trend spotters are coming at this from a different perspective to the consumer – it’s important to remember that not everyone has an iPad. “We must put social media in context – it has a role to play but recommendations by trusted TV critics still also feed into effective recommendation engines,” he added. The research also revealed that second screen viewing habits are not quite as cohesive as content providers would like.
It has interchangeable front lenses with a range of focal lengths (10mm, 14mm, 20mm, 28mm and 40mm). The lenses are surrounded by a circle of lights built into the system, minimising the need for additional lighting. It is suitable for 35mm or Super35 sensors or film – a 2/3-inch HD format is also available. The whole system operates at T5.6, and its controls are at the rear, nearer the user, for ease of use. 11.G25
ITN evaluating LYNXdr cloud ITN is one of a number of companies evaluating Front Porch Digital’s LYNXdr cloud service as a storage and disaster recovery system. “We have many LYNXdr customer wins in the US, but the ITN evaluation is the first for Europe, and a great step forward in the evolution of the platform,” said Rino Petricola, senior vice president and managing director of Front Porch Digital International. Said Ian Auger, head of IT and communications at ITN: “The LYNXdr concept is very interesting and we are pleased to be able to offer some assistance in evaluating it in a real-world environment.” 7.C16
Hawk swoops in ContentProbe Hawk is described as the ‘next generation’ of the IdeasUnlimited’s broadcast compliance recording platform. According to the company’s Managing Director Glyn Powell-Evans, ContentProbe Hawk brings together for the first time all the functions of compliance recording, monitoring, verification, commercial certification and live viewing.
Powell-Evans said this made it simpler and more cost-effective for broadcasters to fulfil their regulatory recording and monitoring obligations. “ContentProbe Hawk establishes a new standard for regulatory recording and monitoring systems by reducing the complexity of the supporting infrastructure, and streamlining the diverse aspects into a more logical and easy to operate workflow,” he explained. ContentProbe Hawk eliminates the need for an internal RF ring main to distribute display feeds through a facility. Instead, broadcasters can ingest and record any unencrypted or encrypted source, and view/monitor on any
combination of Macs, PCs and dedicated monitors. Live sources can be viewed in full resolution on any desktop using ContentProbe Hawk’s web browser interface, or on any HDMI monitor using an IP set-top box, with instant rewind and review of recorded channels. ContentProbe also includes a loudness monitoring engine and patented video fingerprinting, as well as the AdCert system for automated spot transmission reporting. 8.C97
