Build and understand IP infrastructures through tutorials and cutting-edge case studies. Whether you’re migrating from SDI or building a complete greenfield site, learn about the latest technology, how it works, and who is using it.
Saving dollars is one of the reasons broadcasters are moving to IP. Network speeds have now reached a level where real-time video and audio distribution is a realistic option.
Taking this technology to another level, Rohde and Schwarz demonstrate in this eBook how to reduce costs even further and provide contribution and distribution over the internet.
TV Azteca continues to grow in terms of the number of programming hours they produce, as well as by expanding to create content for OTT and other digital platforms. With plans to make a gradual transition to IP distribution, cloud-based operations and 4K UHD, the company was looking to replace aging playout and master control infrastructure with flexible technology that would enable them to efficiently run their current business and easily evolve to meet future requirements.
In part-1 of this series, Challenges, we introduced the basic concepts of the technology behind live OTT delivery. In this article, we dig deeper to help broadcast engineers and technical managers understand the intricacies of HTTP and IP technology, so they will be able to design and support OTT systems more effectively.
Recognising the extremities of the bell curve distribution and the impact large jitter variances have on picture and sound stability is critical. Only when this is understood, do we hope to be able to build reliable, flexible, IP infrastructures that will meet the demands of real-time broadcast facilities.
As broadcasters migrate to IP, the spotlight is focusing more and more on IT infrastructure. Quietly in the background, IT has been making unprecedented progress in infrastructure design to deliver low latency high-speed networks, and new highly adaptable business models, to make real-time video and audio work in IT infrastructures.
If you can see how a magic act is performed, POOF! the magic disappears. Live TV is a magic act because so much of the on-screen magic happens behind the curtain. When a random device malfunctions or fails during a live show, if the talent doesn’t blab the secret on-air, viewers probably won’t notice. As many great engineers and directors have said in so many ways, “They won’t know unless you tell ‘em.”
Live broadcast television was once considered to be unique as every bit of data had to be delivered to the viewers television set in real-time. However, as IT continues to leverage its influence on television, we discover the uniqueness of broadcasting isn’t as exclusive as we may have once thought.
The broadcast industry is moving into a new era, with internet protocol (IP)-based infrastructure and interfaces becoming real and practical elements of broadcast, production, as well as other professional media applications. We are now seeing a true shift toward all-IP operations, and SMPTE ST 2110 and other new standards are making that possible.
