As broadcasters accelerate IP migration we must move from a position of theory to that of practical application. Whether we’re building a greenfield site or transitioning through a hybrid solution, simply changing SDI components with analogous IP replacements will not achieve full COT’s goals and the benefits associated with it.
Moving from the luxury of dedicated point-to-point connectivity in favor of asynchronous, shared, and unpredictable IP networks may seem like we’re making life unnecessarily difficult for ourselves. However, there are compelling reasons to make the transition to IP. In this article, we look at the primary motivation for moving to IP and the benefits it provides for broadcasters.

Low latency networks and non-blocking switches are terms now appearing in mainstream broadcasting. But what do they mean? Why are they relevant? And how do we make Video over IP work?
Innovation in the media and entertainment industry is at an all-time high with devices, backend technologies, operating systems and consumer behaviors constantly evolving. A key element of this evolution is how viewers see, experience, navigate and consume the content they want. Which is why delivering an effective user interface (UI) for video consumption is a top priority for any provider that wants to remain competitive.
Quality Control is one of the many areas where IT and broadcast use similar terms, but the meaning is quite different. Whereas IT focuses on guaranteeing bit rates and packet delivery to improve quality of service and hence quality of experience, video and audio quality is based on satisfying the demands of the human visual and auditory systems. In this article, we investigate how we quantify and measure video and audio streams.
There are many more curators of solutions in the pay-TV market now that there is a move to an all IP infrastructure away from traditional broadcast. Aside from voice, the underlying technologies in pay-TV remain the same as they have for some years i.e. Linux, JavaScript, HTML5, SQL databases and Virtual Machines. What are the implications for middleware – the functional link or glue between the broadcaster service provider and the set top box in the home. Anthony Smith-Chaigneau, senior product marketing, Nagra says the server side has grown-ever stronger and is the nucleus of all pay-TV solutions today.
The bewildering number of video and audio compression formats available is difficult for those new to the industry to come to terms with. For broadcast engineers and IT engineers to work effectively together, IT engineers must understand the formats used, the legacy systems still in place, and the reasoning behind their existence. In this article, from the series Broadcast for IT, we investigate compression formats.
Point to point connections dedicated to delivering video and audio signals have dominated the broadcast industry since the 1930’s. But migrating to IP is compelling engineers to think differently about packetized signal distribution. In this article we investigate the potential sources of congestion and the effects of buffering.
