Software defined networking (SDN) is essential in understanding the types of content being pushed across the network and the demands of the multiscreen environment. Nexidia: The trend continues for more government regulations in the area of access for persons with visual or hearing disabilities. Mandates for closed captioning/subtitles and audiovideo descriptions exist in the USA, Canada, and UK already with the rest of the EU likely to follow suit. S3 Group: We see three major trends impacting on our solution delivery to the test and monitor segment: Firstly, we are witnessing continued strong growth in the consumption of over-the-top video services. But this isn’t uniformly the case as a number of the more forward-looking incumbents have already begun to offer OTT services as part of their bundled offering. Secondly, we are seeing a continuing shift towards consumption of content on devices other than the main TV screen, the so called ‘multi-screen’ phenomenon. Thirdly, we are seeing a significant architectural shift in the platforms delivering TV and related services to viewers. Tektronix: The major development over the last couple of years is adaptive bitrate (ABR) streaming which has caused an explosion in the number of content owners, providers, operators and broadcasters offering OTT streaming services. This will be exacerbated by the advent of the HEVC/H.265 which offers significant bandwidth savings as well as 4K, with some content providers aiming to introduce 4k streaming services over the next 12 months. Triveni Digital: As Internet delivery of content continues to increase, so does the complexities of testing and monitoring. In particular, quality of experience (QoE) can be problematic, as it is highly dependent on the particular path the content takes to reach the viewer, in addition to congestion and impairments found along the way. All of these elements can change dynamically: measurements for one viewer can’t necessarily predict the experience for another. In a captive, managed network these issues are mostly alleviated, but are still not completely eliminated. Witbe: Every service is now IP-based making quality unpredictable. We have moved from a Network-centric to a Usercentric delivery model where the only tangible reality is what customers actually hear and see. This forces the industry to S3 group’s StormTest HS64 variant as launched at IBC2013 deploy a new generation of T&M equipment. Wohler: As broadcast facilities increasingly work in the file-based domain, the need for MPEG and IPTV monitoring is rising explosively. The ability to monitor these additional signals has become critical. Euromedia: How is the Test and Monitor segment responding to these new challenges? ADB: It has become clear that QoS support within the home is a n enabling factor for QoE, but that’s only part of the picture. We have been adding support for TR-069 bridging technologies into our gateway software so that monitoring solutions based on TR-069 can monitor devices in the home which do not support TR-069 directly. These software bridges make it much easier to get a handle on what’s going on within the home network, device by device and service by service, so that operators can take remote action to solve problems. Agama: Operators need insight into the service delivery to each individual customer – regardless of platform. It’s therefore fundamental to have a business support system for service quality assurance that can create transparency under these conditions and offer insight to the entire operator organisation. Necessary properties for such a system include end-to-end coverage and the ability to process and aggregate service focused data from each and every viewing device and monitoring location. It must gather and work with the dimensions of services, customers and infrastructure in the same system; and, handle both the real-time as well as the systematic ‘over time’ perspectives. Most importantly, it has to create actionable insight to support the operator organisation and processes, and the real-world challenges they are handling. Bridge: Manufacturers in the test and monitoring sector have to push hard to keep bringing out innovations that give service providers access to the tools they need now and may need very soon. In the past few months, we’ve added a lot of new functionality to our OTT solution, such as support for https and MPEG-DASH. The landscape is changing so rapidly that manufacturers have to make it possible for service providers to adapt and change direction, knowing that the technology they bought will give them room to do that, and will not tie them into obsolescent standards and methodologies. DTVL: We have announced or introduced a number of new products, recognising some of the challenges faced in deploying such technologies. Examples include a comprehensive MPEG DASH-AVC/264 test suite for those looking to deploy a MPEGDASH player, irrespective of device type, and an HbbTV/CI+ integration test suite, for forward-thinking operators and their supply chain who wish to drive new revenues via HbbTV applications secured via CI+ functionality. Recognising the importance of audio in a media-centric environment, in partnership with Fraunhofer IIS, we have undertaken to introduce a test suite for MPEG-4 HE-AAC conformance, supplementing the company’s existing Dolby testing lab facility. Finally, we are investing in services that aid in application development and deployment, for broadcasters, operators and apps developers. Edgeware: Specialist media analytics solutions focus on improving the efficiency of the collection and analysis of these raw ABR log files to produce reports as near as possible to real-time. We enable an alternative approach by aggregating thousands of ABR logs into ‘virtual sessions’ on our Content Delivery Network (CDN) servers. A session is created for delivery of a specific video file to a specific consumer EUROMEDIA 15
