Premier 4K acquisition LIVE S IS LIVE recently put together a working group to explore the technology and workflows required to deliver live, 4K, multi- camera event coverage from an outside broadcast unit, which culminated in a field test at St James Park on 2nd February. Working with major camera and equipment suppliers, SIS LIVE has conducted proof of concept tests at base using a range of cameras coupled with its latest 3G capable outside broadcast unit OB 14. All recent SIS LIVE trucks have been built to be 3G capable, designed to handle HD signals. This has involved testing of signal flows, the use of lenses suitable for live event coverage, as well as the integration of recording technology. The testing continued on 2nd February with a Premiership football match featuring Chelsea and Newcastle captured in full 4K using the Sony F65 camera paired with a Fujinon 75mm-400mm lens, recording to the camera’s onboard 256gb flash memory cards. Additionally, one of Psitech’s 4K Vortex systems and two specialist engineers were flown over from the United States to take part in the testing. Through this SIS LIVE has gained experience in manipulating 4K pictures within an OB truck setting, and experimented with the capability of the Psitech device to understand its potential applications in the live sport genre. SIS LIVE’s camera operatives gained invaluable experience operating the F65 demonstrating how 4K acquisition requires a different approach to camera operation; in effect, shooting wider, which then allows VT operatives and production staff to create multiple shots from the same camera position. Phil Aspden, Commercial Director, SIS LIVE says 4K technology is still at an early stage and there is a huge difference in the requirements of single camera capture compared to that needed to transmit live shows. Live sport, for example, requires very reliable equipment with very low failure rates. If a shot is missed due to failed equipment there is rarely an opportunity to restage the event. This becomes even more challenging when the technology has to be compact enough to be mobile and able to operate from a range of locations. Outside broadcast vehicles provide finite space which limits the amount of equipment that can be installed. OB environments are often challenging which puts extra demands on the equipment so any 4K equipment needs to be as compact, portable and reliable as possible to be able to capture the range of shots we currently achieve in OB scenarios. SIS LIVE supported the BBC and NHK in their super hi vision transmissions of the Opening and Closing ceremonies and other sports events at the London 2012 Olympics. In the preparations for the project they provided expert technical and logistical OB support for the Japanese NHK crew tasked with integrating the specially adapted outside broadcast vehicle and audio equipment shipped in from Japan. SIS LIVE provided dedicated workshop space and technical support at their Langley OB base to assist with the integration of the NHK audio equipment into the SIS LIVE audio truck which operated alongside the NHK SHV OB unit. David Meynell, Managing Director, SIS LIVE says it is inarguable that 4K technology is going to be part of our future. “If the popularity of 4K consumer technology continues to rise we will reach a point where broadcasters want to transmit live events in 4K, and this means that SIS LIVE needs to be ready to deliver. As with all new technologies we are monitoring its development and potential demand closely, ensuring that we remain at the forefront of technological development.” 70 | TV-BAY MAGAZINE TV-BAY075MAR13.indd 70 11/03/2013 16:52
