ASK THE EXPERTS OTT Anupama Anantharaman Director, Product Marketing and Business Development at Interra Systems. IN TODAY’S MEDIA INDUSTRY Q. how is the media industry changing today? The media industry, especially the digital TV industry, is going through some revolutionary changes both in terms of how video is delivered and how it is watched. Until a few years ago, consumers watched TV programs that were delivered via a dedicated and controlled network. Content was aggregated and delivered to viewers via cable or satellite to set- top boxes on the consumer side. Now, viewers are increasingly shifting toward watching content when they want, where they want, and on the device they want. Content is streamed per user requirements, on demand, and in the resolution supported by the playing device. Another reality is that video quality and viewing experience matter greatly. If video is interrupted, or has poor picture quality, customers are going to abandon the service and seek other alternatives. It’s a total shift in control, with content now being requested by consumers according to their preferences. These trends have pushed the industry to come up with new, innovative technologies and standards such as ABR, HEVC, 4k, MPEG-DASH, etc. To be competitive, video service providers will need to offer or expand OTT content, as the case may be, and add these new technologies into their existing infrastructure. Q. what is the difference in streaming in ott workﬂow for vod vs. live streams? In both cases, whether live or video-on-demand (VOD), segments for every proﬁle that is created are made available on the origin server. However, there are some differences. With VOD content, the segments remain static whereas with live content, each segment is uploaded in real time after it is encoded. After that, the 42 | KITPLUS - THE TV-BAY MAGAZINE: ISSUE 114 JUNE 2016 provider also has to take additional steps as to how to manage the elapsed content – whether to keep old segments on the server for later viewing or not. There are a couple of other points that service providers need to keep in mind, especially when they are considering QC and monitoring tools. Broadcasters store and manage a large number of VOD assets. In a ﬁle-based workﬂow, they have the time and luxury to go through each asset, analyze the quality and, if required, take corrective actions to ﬁx the issues. For live ABR delivery, relying on the ABR transcoder to produce error-free streams would not be wise. You need to have monitoring systems that can look at multiple manifest ﬁles simultaneously and provide alerts in real time for both errors and quality issues. Q. what is orion ™ -ott? ORION™−OTT is a software-based, over-the- top (OTT) monitoring solution for checking content integrity and related network performance of ABR content for multiscreen service delivery. ORION-OTT is designed to help customers deliver content with superior Quality of Service (QoS), and Quality of Experience (QoE). It’s a software-deﬁned product which can run on any industry- standard server and can monitor hundreds of manifest ﬁles on a 1 RU server. We have designed the product to address scalability and high-density requirements. While traditional manual monitoring methods are too time- consuming, expensive, and unreliable, and hardware-based monitoring solutions make it difﬁcult to keep up with the rapid pace of new video formats, protocols, and monitoring enhancements, ORION-OTT absolves these issues, guaranteeing the highest level of QoS and QoE for live and VOD OTT services.
