MANAGEMENT December 2016 19 Reliable QC and monitoring solutions are essential in OTT environment BY KANISHKA TONGYA Over-the-top (OTT) TV and video revenues in the Asia-Pacific region are expected to skyrocket to US$18.4 billion over the next five years, up from $5.7 billion in 2015, according to a recent study from Digital TV Research. Yet, delivering error-free and high quality content can be an issue for broadcasters without a reliable set of quality control (QC) and monitoring tools. From an OTT monitoring perspective, broadcasters should choose a solution that provides comprehensive HTTP checks for both live and linear applications. Quality of service (QoS) assurance parameters that broadcasters will want to monitor include content download time, latency, macroblocking, freeze frames Figure 1 and black frames. Beyond video, broadcasters must also check loudness, silence and audio levels. Ultimately, this will ensure that their viewers can enjoy a highquality video and audio experience on any device. Having visibility into the entire workflow is another key requirement for ensuring optimum QoS and quality of experience (QoE). As content in an OTT workflow is stored on origin servers, content delivery networks (CDNs), as well as edge/cache servers, it can be challenging to detect the delivery source of QoS problems. A QC solution with advanced functionalities such as centralised management, QoS and QoE checks, and real-time error alerts for problem detection and troubleshooting will streamline this process. OTT technology and require- ments are always evolving. Broadcasters will want to select a monitoring tool that is flexible and scalable, enabling easy growth as well as support of next-generation technologies and standards. Finally, there cannot be any trade-offs between efficiency and accuracy. Deploying an OTT monitoring solution that works in tandem with a file-based QC tool will allow broadcasters to quickly and correctly address any issues in live and linear workflows, all the way from ingest to delivery. (See Figure 1.) The result is better QoS and QoE for OTT viewers. Finding a QC and monitoring solution that meets all of these requirements for video delivery in the OTT world can be challenging. But poor video quality is not a risk that broadcasters can take anymore. Viewers expect a consist- ent, crystal-clear video experience across all device types, including TV, PC, smartphone and tablet. Using a combination of Interra Systems’ Orion-OTT monitoring solution and Baton file-based QC tool, broadcasters have a complete video-quality assurance solution for the OTT landscape that will ensure an exceptional QoS and QoE for viewers and enable them to gain a competitive edge in the marketplace. Deploying an OTT monitoring solution that works in tandem with a file-based QC tool will allow broadcasters to quickly and correctly address any issues in live and linear workflows, all the way from ingest to delivery. Kanishka Tongya is senior International Business Development manager at Interra Systems. Innovation key in technology transformation, says SI As technology evolves, broadcasters are primarily concerned about the need for “future-proof” solutions and how these solutions can help them migrate existing workflows in order to increase workflow efficiency. “Future-proof solutions bridge the gap between current and future technological developments in the broadcast industry, as well as changes in the user viewing behaviour,” Andreas Höflich, PR manager for systems integrator Broadcast Solutions, told APB. To demonstrate the possibilities of how broadcast centres can be built to suit the needs of today’s broadcasters and be upgraded to tomorrow’s requirements, Broadcast Solutions and event partners IHSE, Riedel and Zenon Media hosted the Broadcast Innovation Days Asia 2016 with a presentation of the latest technology innovations. With the theme Think Big — Start Small — The Power to Scale, more than 300 broadcast professionals gathered in Jakarta, Indonesia on October 31 and in Hanoi, Vietnam on November 3, to discuss technological advancements and solutions that are needed to cope with the demand for faster workflows and economies of scale against the backdrop of increased competition. Broadcast Solutions exhibited its portfolio of future-proof solutions and products, which includes the streamlined outside broadcasting (OB) van family, slomo.tv’s multi-channel recording and replay servers, as well as Satcom antennas and Robycam stabilised rail and “flying” camera systems. Addressing the need to access equipment at every stage of the transmission chain, IHSE demonstrated its Draco tera KVM (keyboard, video and mouse) switches, which allow operators to manage More than 300 visitors attended the Broadcast Innovation Days Asia 2016 in Jakarta and Hanoi, which was hosted by systems integrator Broadcast Solutions and its industry partners. devices from their workstations. The main aspect of IHSE’s systems, according to the company, is its modularity and expansion features, which enable operators to expand and extend facilities while managing a wide range of content and data. Designed to simplify workflows in a radio station, Zenon Media presented “the modern radio system”, which handles import and management of data, playlist, and playout on multiple channel broadcast layers. MicroN, the newest member to Riedel’s MediorNet family, was also showcased at the events to help broadcasters adapt to a wide variety of production Eyeheight LE-2M legalisers return to UK TV series set Eyeheight LE-2M legalisers were recently deployed for the production of the latest series of the UK TV show I’m a Celebrity ... Get Me Out of Here! Designed for use in live TV content creation and post production, Eyeheight’s LE-2M legaliser ensures that incoming signal video is held within the required broadcast colourspace parame ters, such as EBU-R103. The SDI or HD-SDI source signal is auto-detected and the appropriate legalising format then applied. The LE-2M incorporates six user memories plus common presets. Additional legalisation Eyeheight LE-2M legalisers were recently deployed for the production of the latest series of the UK TV show I’m a Celebrity...Get Me Out of Here! features include automatic luma overshoot and undershoot suppression together with luma and chroma gain, black level adjustment, hue rotation, adjustable clipping levels and soft-clipping-knee levels. An ‘out-of-gamut’ indication feed displays overshoot or undershoot severity and shows the user where on the picture any signal correction is being performed. Automatic real-time control of perceptual loudness and true peak level are also provided. Originally developed in Britain by ITV Studios and first shown in 2002, I’m a Celebrity ... Get Me out of Here! is a reality TV series produced by ITV Studios and licensed globally. The latest series features former footballer Wayne Bridge, dancer Jordan Banjo from Diversity, media personality Carol Vorderman, Olympian Sam Quek, presenter Lisa Snowdon, and actors Adam Thomas and Larry Lamb. challenges. Designed with decentralised routing capabilities and easy-to-use configuration options, Riedel believes that the MicroN-based systems are futureproof solutions broadcasters will require, as the industry migrates towards fully IP-based production environments. Rajveer Singh, general manager, South-east Asia, Riedel, concluded: “The attendees were keen to know how these technologies and new workflows would enable their daily operations to be more efficient. The products highlighted at both events were a good opportunity for attendees to understand how they can benefit from them in many ways while relating it into their own context. “There was also a good level of engagement at the demonstration sessions, and the attendees requested for more seminars so as to foster in-depth understanding.”
