A versatile compression infrastructure
Christophe Delahousse, president, Thomson Video Networks, argues for a hybrid compression strategy that offers the best for all worlds
In today’s ever-evolving technology and competitive landscape, media enterprises face tremendous challenges as they adapt their operations to stay on the leading edge of content delivery. Linear services and traditional television are still important, of course, but now consumers control what they watch and when they watch it. And they’re demanding access on an ever-growing range of devices from smart phones to tablets to internet TV. For traditional broadcasters, adapting to multi-screen and multi-platform delivery can be costly, bandwidth-intensive, and difficult to monetise. Plus, a whole new generation of pure- play OTT providers are turning up the competitive pressure. Throughout the digital
revolution, advanced video compression and content delivery technologies have

played a key role in helping broadcasters provide a premium viewing experience for their customers. At IBC2014, we expect many of these broadcasters to be looking for compression solutions that can effectively address the challenges of multi-platform delivery.
Building a modern live
broadcast infrastructure requires much more than simply adding OTT capabilities to a traditional linear broadcast subsystem. In order to support traditional as well as new- media broadcasters and pay- TV operators, a video infrastructure must be all- encompassing and provide seamless support for many different codecs, networks, and devices. Ideally, this approach combines premium encoding capabilities with dense transcoding for turnaround
services, with an emphasis on the following criteria: Flexibility to transcode and deliver OTT and IPTV services to a constantly evolving ecosystem of devices and applications, in all necessary output formats Continued high-quality delivery for traditional broadcasts over cable, DTH, and DTTV A transcoding workflow that can be adapted easily by adding ABR encoding profiles, adding or removing channels as required, changing resolutions, or upgrading to new and emerging codecs such as HEVC High-performance
compression, multiplexing, and ad insertion, premium encoding capabilities and dense transcoding Robust channel
processing capabilities for
branding, ad insertion, and audio management including loudness control In today’s media
environments, video compression resources may be running on physical hardware appliances, virtual servers, or in the cloud. At Thomson Video Networks, we propose a hybrid strategy that offers the best of all worlds. This approach combines video-optimised hardware solutions with software-based encoding that runs on lower- cost and generic physical servers, virtualised servers, a cloud infrastructure, or some combination of the four. As a result, network operators benefit from the advantages of virtualisation and cloud computing without having to compromise on quality of service, SLAs, video quality, and any of their other critical
operational standards. Plus, they’re able to choose the mix of cloud or on-premise technologies that are most appropriate for a given project or service.
A video infrastructure that meets these requirements provides everything broadcasters need for profitable and convergent multi- platform video delivery, while maintaining the core linear operation. At IBC2014, Thomson Video Networks is presenting Behind Every Screen – an approach specifically designed for smooth integration of both multi-screen and broadcast services with optimised operational costs. 14.A10
Supporting TV Everywhere and OTT Imagine Communications
Compact and clever acoustic monitoring Genelec By Michael Burns
A new collection of Smart Active Monitoring (SAM) products, designed to adapt automatically and accurately to acoustic environments, has been launched at IBC. Genelec has introduced two new compact two-way monitors, the 8320 and 8330, and a new subwoofer, the 7350. The company also unveiled a new version of its Genelec Loudspeaker
100 theibcdaily
Manager software (GLM), complemented with a new measurement microphone and network adapter unit. The 8320 and 8330 monitors
feature Genelec’s Minimum Diffraction Enclosure (MDE) made of recycled die-cast aluminium as well as the advanced Directivity Control Waveguide (DCW) technology. The 8320 and 8330 monitors and the 7350 subwoofer offer floating point DSP engines for signal processing and Genelec-designed Class D amplifiers.
Genelec claimed its SAM
technology was an indispensable tool when dealing with challenging small room acoustics. SAM automatically optimises and aligns each monitor for relative levels and time of flight, as well as individual room response compensations. If monitors or production
projects move between rooms, SAM technology is intended to achieve high monitoring consistency by always providing a neutral sound stage imaging with low distortion. 8.D61
By Carolyn Giardina TV Everywhere and OTT services require the creation and management of many parallel outputs—meaning complex workflows. “As a result, media organisations need a flexible, new approach to both media processing and workflow management to enable them to quickly launch new services, scale with expanding opportunities, and adapt to changing market dynamics. Imagine Communications is showcasing an array of scalable systems designed to address these requirements,” said CTO, Steve Reynolds.
That includes Imagine’s SelenioFlex software-based media processing system, which is designed to provide flexible, high-quality, live and file encoding, transcoding and processing at any point in the content chain, supporting applications from source acquisition to Adaptive Bit Rate delivery and Video on Demand.
The SelenioFlex File automated, high-volume, file-to-file media transformation software
and SelenioFlex Live multiscreen encoder are both built on Imagine’s workflow management platform, enabling extensible, customisable, software-defined workflows.
For high-density multichannel live and linear TVE and OTT applications, the SelenioNext ABR transcoder offers up to 10 times the processing density and power efficiency of competing systems, claimed Imagine. Using a standard IT platform, SelenioNext could replace a headend of dedicated video processing equipment, while creating a foundation for future transcoding needs, the company said.
Also featured is the
SelenioEdge content delivery network software, designed to provide scalable, cache-efficient streaming to end-user devices, enabling complete TVE and OTT workflows. 7.G20
