Quality assurance for IP transmission
NTT Electronics By Will Strauss
Broadcasters wanting to use a level 2 or level 3 shared VPN rather than satellite to send IP streams are the target audience for NTT Electronics’ new NA8000. Making use of the error
correction algorithm LDGM, the contribution-grade ASI-IP converter is designed to maintain footage quality throughout a transmission and can recover packets that are lost due to network
instability such as an increase of jitter. Intended for sending high bitrate data like HD or Ultra HD content, the NA8000 works with ASI and Gigabit Ethernet and can cope with up to 160Mbps for each ASI interface. AVC, HEVC and MPEG-2 codecs are all supported. According to NTT: “By
using NA8000 you can maintain the
quality of your content and reduce the cost of transmission significantly. For sending, all you have to do is pull off the BNC-cable from your transmitter, plug it into the ASI-input of NA8000 and connect a network cable to the Ethernet port.” 2.C50

Realtime performer: InvisaPC enables smooth migration from physical desktops to virtual machines
IP extension expands KVM control Black Box
By Michael Burns
InvisaPC, a KVM-over-IP system that works over a local area network (LAN) or the web, has been released.
InvisaPC extends and
switches DVI-D video and USB- HID signals with low latency to deliver realtime performance for video, keyboards and mice across IP networks. This enables hardware-based desktop extension of multiple physical CPUs or virtual machines. The InvisaPC is a scalable solution; Black Box said users can start with a small point-to- point extension setup and
Derive Wikipedia topics from audio
BBC R&D By Adrian Pennington
As part of its remit to deliver the future of public service media the BBC's estimable scientists can always be relied on to put theory into practice faster than nearly anybody. Collaboration is a key part of its success helping the researchers better understand the potential challenges and benefits of emerging and established technologies, and to drive open standardisation.
“This vital work enables R&D to advise the BBC on what is coming in the future; what it needs to be involved in and influence; what the likely winning and losing technologies are; and what the BBC needs to lead, follow or ignore,” explains Andy Bower, head of external relations, BBC R&D. Take a close look at its exhibit over in the IBC Future Zone and you will see COMMA. This is an intriguing project undertaken with partners Kite and Somethin' Else, funded by the UK's Technology Strategy Board and aimed at metadata extraction.
“High quality metadata is
required to allow audiences to search, discover and personalise content. We are developing techniques to address the challenges of

transition to an unmanaged, network-based matrix switching configuration. The system provides integrated support for back- racked PCs and virtual desktops. Desktop virtualisation is deployed through a PC or server that hosts multiple virtual desktops (Microsoft only). However, the workstations are OS-independent when using an InvisaPC transmitter, InvisaPC transmitters

creating this metadata, whether from today’s content or that taken from the vast wealth of content held in archives.” Cloud Marketplace for Media Analysis (COMMA) is showing an automated metadata generation workflow and the 'Kiwi' topic extraction algorithm, which can derive Wikipedia topics from audio. “We are aiming to show how we think that the production, distribution and delivery of content could change as networks and systems for production and distribution become increasing based on flexible IP networks, architectures and tools, and how this will bring massive benefits and opportunities for content producers and audiences alike,” he adds. There are also demos
through the RESTful API with an example interface to navigate within radio programmes using data generated through COMMA. “COMMA is a completely generic metadata extraction platform that can run in practically any environment, scale fluidly across public and private cloud infrastructure, and run nearly any Linux- compatible algorithm code – usually without modification – against single files or petabyte- scale archives,” describes Bower. “The simple HTTP- based API allows trivial integration into existing ingest workflows and tool-chains, allowing metadata to be generated and delivered without any additional human intervention.” Streaming of UHD content for interactive navigation on a tablet has only recently become possible, and the BBC is one of the first to show this working using HTML5 rather than via a native app at IBC2014. 8.F18
