Innovation in cameras moving to 4k

For a number of reasons, wireless camera links needed time to migrate to 4K. However Broadcast Sports International, BSI, designs their own cameras and builds their own hardware and their transition to 4K is already complete.

In an industry where innovation is key, hire companies buy what is on offer from the manufacturers, however BSI has taken a different path and has created a series of specialist wireless cameras to enhance any sports or news coverage.

BSI, provides wireless cameras and other specialist cameras on a hire basis. The company offers roof-mounted cameras, goal cameras, ref-cams, and wireless microphones, all of which were originally designed for motor sports applications, but now find uses in all kinds of live broadcast situations. BSI has become something of an industry heavyweight - its kit is used in some notable large projects, such as the on-board cameras for NASCAR, the cameras and mics for the PGA Golf, and the wireless cameras for the Presidential Inauguration in the USA.

BSI has always designed and created their own kit, and the company has recently developed the new Tilting Ref-Cam – a body-worn POV camera now with remote tilting capability - a fully remote controlled drone camera with zoom and focus, and two special cameras created for Rugby coverage: the Lineout camera with wireless remote heads and the wireless corner post camera, a specialist POV camera which adapts from Rugby to Snooker.

BSI’s own HD wireless camera-back system, ‘Real Freedom’ is a complete solution for wireless cameras in live productions, comprising of integrated Ethernet camera control which allows RF, audio and paint parameters to be controlled by telemetry via the camera control unit which is located back in the OB truck.

BSI’s UK office is working on some huge productions, among them the Aviva Rugby Premiership and F1 motor racing. BSI also provides wireless cameras and specialist cameras on a daily hire basis with technical crew if required. The Real Freedom system has proved invaluable with a quick and reliable set-up for the dry hire market.

Moving to 4K – R&D and testing

While major sports events are already aired in 4K, the shots from the specialist mobile and wireless cameras are still captured at the 1080p/50/3G standard and up-scaled to 4K. However BSI’s R&D teams in Watford and Baltimore have been working for some time on the encoding and transport of the 4K video stream and completed this stage of the development a while ago.

The first live test coincided with IBC, and took place in September at the Aviva Rugby Premiership in Northampton.

BSI’s UK Managing Director, Tony Valentino, says, “This was the industry’s first test of a 4K wireless camera system with low delay and there is no doubt that it demonstrated exceptional picture quality. Everyone who saw the images from the camera was blown away by the video, and it was difficult to believe it was not from a cabled camera.”

A second test took place at the Rugby Premiership in October, where BSI added Ethernet camera control and 4x3G signal distribution, and the full 4K wireless system was demonstrated to the London audience at the SVG’s Future Sports event at the Kia Oval in November.

Now BSI is putting the final touches to the extra features that will turn its 4K system into a fully integrated 4K wireless package.

BSI’s Tony Valentino says “Wireless should work just the same as a camera that is plugged in. The quality and reliability of the wireless links is now pretty well the same as cabled cameras so a lot of people feel happy to operate them themselves now and the Real Freedom system has become a very successful part of this transition. The industry is now waiting for the key camera manufacturers to deliver more 4k cameras suitable for wireless applications. Currently we only have a very limited choice of cameras offering the required features for wireless integration.”

BSI offers its 4K solution as part of a turnkey package with on site installation, frequency co-ordination all managed by their experienced technical crews.

What is next in OTT
Mary Kay Evans In the past year alone, we’ve seen a substantial increase in the amount of OTT content that’s being streamed. In the first quarter of 2018, there’s been a 114 percent year-over-year growth in streaming video hours, and those numbers are only expected to rise. With OTT revenue predicted to reach $16.6B in 2018, a 40% gain over last year, there’s no question that OTT is booming, and that there’s never been a more critical time to pay attention to the space.

IBC in a post Brexit world
Peter Savage 2 Cast your mind forward and we are not in 2018 but next year and, yes, it’s you and me walking to the departure lounge to catch the plane to IBC just as I, and perhaps also you, have done for the last 25 years. (By the way, where is my long service award – and perhaps a new pair of shoes as I must, surely, have walked the equivalent of five Caminos covering the 12 halls in the Rai). We are at the gate and my imagination kicks in as I hypothesize on what the trip might look like next year. I leave it to you to decide which is closest to what might be to come.

The Pace of Change
Dick Hobbs - new

The youngest human to stand on the moon (so far) was Charles Moss, the lunar module pilot of Apollo 16. Charlie had a wonderful claim: his father witnessed the Wright Brothers’ first flight at Kitty Hawk, and lived to see his son on the moon.

Does anything capture the speed of technological advance better than that? The whole of the history of powered flight in one lifetime.

Ruth Matos Interview - A Career Unfolds
Ruth Matos We first met Ruth when we employed her as a student to help with our live studio at BVE in 2013. We were struck by her determination, passion and ‘I’ll do anything to help’ attitude. We became friends of Facebook and have since seen her career in the industry develop and unfold. We thought it was about time to catch up and share her inspiring story of where she is now, how she got there and the challenges she has faced along the way.
