Ryder Cup trial for UHD learning curve

BT Sport wants 4K for 2015-16 season
Conference Analysis By Chris Forrester
IBC delegates heard Alex Green, BT Sport’s director of TV, say the broadcaster was working “very hard” to see 4K transmissions of its Premier League soccer matches during the 2015-16 season. BT Sport conducted the first end-to-end all 4K trial in the UK (of a Rugby final) and the recording is being played out on the Ericsson stand (1.D61). “This gave us a great deal of confidence. We are also doing a lot with 4K camerawork across upcoming sports events. We are also using in the studio a couple of 4K ‘stitched’ images allowing us
to see the whole field of play, and this is very useful and we are excited by this.” Green was speaking during
the ‘More Pixels or Better Pixels?’ session, and he said he sensed a strong enthusiasm for the technology from the public. “I invested in a 4K display for home, and showed my familyHouse of Cardsin 4K and it truly generated the ‘wow’ factor. There is an appetite [from the public] for quality. The demand is there.” Green said that sport
would be a major driver, and perhaps ‘the’ driver for 4K adoption. “We see 4K being a natural evolution right across the industry. Live sport is all about immediacy and UHD is perfect.”
First fruits of partnership unveiled Vislink
By Ian McMurray
Said to be the world’s first portable IP news gathering solution capable of simultaneously and reliably aggregating microwave bandwidth with multiple cellular data connections at unprecedented quality, TVU Networks and Vislink have announced the launch of a next- generation TVUPack with Vislink’s integrated hybrid microwave IP technology. The TVUPack is the first fully-integrated product to emerge from the partnership between TVU Networks and Vislink announced in April. The joint offering integrates the TVUPack TM8200 with Vislink’s hybrid microwave IP technology. Utilising TVU’s Inverse StatMux IP transmission protocols, the TVUPack is able to combine multiple cellular data connections with Vislink’s hybrid microwave IP technology to give broadcasters unrivalled flexibility, says Vislink,
letting them transmit HD video simultaneously over cellular and microwave connections with sub-second latency. As a fully integrated IP newsgathering solution, the TVUPack is claimed to combine best-of-breed cellular and IP microwave transmission technologies into a single mobile lightweight backpack.
“This integrated package is the first in the world to combine the best in cellular transmission technology from TVU with Vislink’s award-winning microwave uplink solutions. This integrated joint solution enables customers to overcome the inherent limitations of cellular and microwave infrastructure, when they are used alone. The new generation TVUPack combines both infrastructures into a single small backpack and will significantly increase the transmission success rate in extremely challenging conditions. We look forward to working with TVU to provide additional transmission solutions in the future,” said Mike Payne, CEO of Vislink. 1.A69
With Sky about to extend its UHD trials with a shoot at the Ryder Cup – in order to settle on a programme chain for different genres of sport – chief engineer Chris Johns has compiled a ton of format experience to apply to his co-chairmanship of the DTG UHD Group. “There has been a push by the consumer vendors to make UHD happen and we are not drawn into as trap.” he said at IBC. “We are watching very carefully what consumers are actually getting. “There is a worry with the Digital Europe release where they have committed to the basics of UHD, and are sticking to 8-bit. All broadcasters want to push the boundaries and go for 10-bit and above simply to deliver a bigger, better picture,” he added. “By sticking to 8-bit we have a legacy which we are trying to move away from.” The DTG is dealing with the same issues everybody has with UHD. “There is that big push to make it happen, but then you take a deep breath and suddenly realise there are all the nuances of frame rates, Phase- 1 and Phase-2, and dynamic range,” said Johns. “Do we have to have HDR now? How do we deliver HDR through the production system?
In Brief
SDN-inspired cloud storage
Chris Johns: “How do we deliver HDR through the production system?”
“It is very easy to produce a
screen that delivers all those bright colours, but if you want to get it through an entire production chain you have to look at that seriously,” he added. “The DTG is pushing for what the consumer needs, and what we need in production, post and delivery.”
On the issue of frame rates, Johns would like a utopian world with one standard. “When we looked at this, and the proposal went forward for 60 and 120 fps (ITU Rec) we quickly discovered that lights, cameras, shuttering and lighting in a 50Hz world produce strobing effects,” he said. “So we still have to have the 50Hz variant for a time. It may be several years before we get to a single harmonised frame rate.”
Dante delivered on a card Sennheiser By Michael Burns
A Dante card for the EM 9046 receiver has been launched, enabling the Digital 9000 microphone system to be integrated into Dante audio- over-IP networks. Sennheiser said users would be able to conveniently route the system’s high-definition audio data via Audinate’s Dante Controller.
The EM 9046 DAN extension
card simply inserts into the expansion slot of the EM 9046 eight-channel receiver. Internally, the card features sixteen audio inputs to send the digital audio and command signals over the Dante network. Connection is
via two Gbit RJ45 sockets that serve to establish two redundant network circuits or daisy chain the signals. The card works with sampling rates of 44.1/48/88.2 and 96kHz at 24-bit resolution. Sennheiser will also adapt
its Wireless Systems Manager software to include a monitoring function for the Dante card. Like the card, the new version 4.2 will be available from October and will allow users to listen to and monitor the EM 9046’s Dante audio streams from any point in the network.
The company also announced that Technology and Production Center Switzerland (TPC) would be among the first users of the EM 9046 DAN Dante card. 8.D50
The veil has been lifted for the first time on the underlying architecture of Signiant’s redesigned cloud platform, which supports the company’s Media Shuttle and SkyDrop file movement products. The new architecture, driven by the company’s introduction of cloud products, involves the separation of the software that controls file transfers, the control plane, from the data plane, which is the software that performs file transfers. This concept, borrowed from the principles of Software Defined Networking (SDN), allows Signiant to use the cloud to increase the pace of innovation. The new SDN-like architecture has enabled Signiant to take an incremental approach to SaaS
implementation. “Because the piece that initiates and controls the file transfers is in the cloud, we can evolve it much quicker than if it was on- premise software relying on customers to perform upgrade and maintain it,” explained Ian Hamilton, CTO at Signiant. “Historically, our software was installed on the customer’s infrastructure on-premise. Many companies just replicate their software and deploy it on virtual machines in the cloud, but we rebuilt our platform in a cloud-form architecture to offer global availability, scale, automatic updates and so on.” 14.L08
RackMac for Pros Sonnet is featuring a technology lineup that includes the RackMac Pro rackmount enclosure for the Mac Pro computer and Thunderbolt Pro P2 card reader. The RackMac Pro – supporting the rackmount installation of one or two Mac Pros – provides a front panel power switch and USB 3.0 port for each computer, while panel-mounted cables connect each Mac Pro’s Gigabit Ethernet, USB 3.0, HDMI, and power ports to ports on the back of the product. The Thunderbolt Pro P2, based on 10Gb/s Thunderbolt technology, can ingest footage from individual P2 memory cards at 70 MB/s. At IBC, Sonnet is also featuring the xMac Pro Server, a rackmount technology with built-in Thunderbolt 2-to-PCI Express expansion for the Mac Pro; and the xMac mini Server. 7.G02
