With any technology project, engineers run at break neck speed to achieve tight deadlines at ever decreasing costs. But security is a new aspect anybody migrating to IP must consider from the out-set. In this article, we investigate security, what it means, and most importantly, who is responsible for it.
As the television business has become more global, and evolving consumer devices spawn the need for ever more formats, there has been an explosion of the number of versions that are needed for an item of content. The need to provide tens to hundreds of language versions provides added complications, with localized versions often being created at dispersed dubbing and captioning facilities. The Interoperable Media Format (IMF) has been developed as the solution to the sensible processing of motion pictures and episodic shows. In the linked e-book, Rohde & Schwarz explain IMF and introduce Clipster as a platform for IMF workflows.
In principle, IP systems for broadcasting should not differ from those for IT. However, as we have seen in the previous nineteen articles in this series, reliably distributing video and audio is highly reliant on accurate timing. In this article, we investigate the key components needed to build a reliable broadcast IP infrastructure.
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.
