Probing The Data Stream
By Simen K Frostad, Chairman at Bridge Technologies
Bridge Technologies’ VB220 and VB330 digital media monitoring probes offer a highly developed and efficient solution for IPTV and streaming media applications. As part of a larger VideoBRIDGE monitoring system, or used with third-party network management systems, these probes give engineers a complete and detailed view into the data stream, wherever in the delivery chain they are deployed. Both probes are based on Bridge Technologies’ zero-tolerance approach to data errors in the stream: rather than using arbitrary Sophisticated filtering and thresholding allows staff to adapt alarm message generation to operational conditions, and one of the key features of the system is the clear graphical presentation of the live status of hundreds of datastreams, without swamping the operator with too much information. The probes deliver huge density from a compact form factor: the VB220 can monitor up to 260 streams, and three VB220 blades can be placed in one 19” 1RU chassis, giving a total monitoring capacity of 780 streams per chassis. This is a powerful tool for any network engineer attempting The VB220 digital media monitoring probe multicast parameters based on subjective detection on multiple VLANs or criteria such as picture quality, the in the process of IGMP tracking.

Engaging Audiences With OTT Smooth Streaming
By Helge Høibraaten, CEO Vimond Media Solutions
Smooth Streaming is the scalable Microsoft® technology that allows media organizations to stream content to any Internet-enabled device with no buffering, regardless of bandwidth or age of the device. Smooth Streaming automatically detects local bandwidth and video capabilities, and adapts the stream accordingly in realtime to optimize the experience for the given viewer. The result is a consistent, uninterrupted viewing experience, whether the viewer can accommodate full HD streams or something less. Smooth Streaming technology was first used to deliver ondemand content during a largescale international sporting event in 2008, and it has been gaining steam ever since. Smooth Streaming can help any broadcaster that aims to extend audience engagement and create new revenue opportunities. Vimond’s expertise in Smooth Streaming runs deep. We spun off from Norway’s largest commercial broadcaster TV 2, which was an early adopter of Smooth Streaming and the first broadcaster in the region to use the technology in a multiscreen OTT environment. While part of TV 2, Vimond developers built TV 2 Sumo, Scandinavia’s biggest commercial online video enterprise. We’ve since helped broadcasters all over the world design Smooth Streaming infrastructures. We know well the challenges broadcasters face, both in terms of selecting the right streaming technology and adapting that technology to their workflow. Vimond is also a partner with Akamai, one of the world’s largest CDNs, which affords us an even greater depth of expertise. Finally, we have experts on the actual playback equipment, which gives us one of the best in-house environments for front-end Smooth Streaming development. All of this know-how is crucial to success in today’s streaming market. When approaching a new streaming infrastructure with any customer, we first work together to consider a few crucial points: • Type of content – Are you going to stream long-form content or short-form? Will the content be live, VOD or both? Live streaming requires a video encoder, while VOD content requires a transcoder. • DRM – Does the content require DRM, or is it free to air? Content coming from Hollywood, for example, requires DRM. Microsoft’s PlayReady® DRM technology, which is integrated with Smooth Streaming, is approved by the Hollywood studios, making desirable

Hollywood content easy to exploit. • Content Delivery Network (CDN) – How many viewers do you expect? Hosting the expected traffic in-house, or do you need help from a CDN? Deciding on a CDN is an important and complex decision involving many variables – a decision best made with expert advice. Determining these factors ahead of time is critical to building a viable Smooth Streaming infrastructure – an investment that can help keep customers and build revenue for years to come.
