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.
NDI (Network Device Interface) is a free protocol for Video over IP, developed by NewTek. The key word is “free.”
Timing accuracy has been a fundamental component of broadcast infrastructures for as long as we’ve transmitted television pictures and sound. The time invariant nature of frame sampling still requires us to provide timing references with sub microsecond accuracy.
For the past year an international group of technology companies, funded by the European Union (EU), has been looking into the use of 5G technology to streamline live and studio production in the hopes of distributing more content to (and from) viewers faster and more efficiently. Due to the restrictions imposed because of the coronavirus, most of the work thus far has been completed remotely.
In the last article in this series we looked at how KVM improves control, reliability, security and integration for multiple devices and cloud systems. In this article, we look at how latency is addressed so that users have the best quality of experience possible.
The need for synchronization rears its head in so many different endeavors that it has to be accepted as one of the great enabling technologies.
Having a collection of PCs and MACs stacked under a desk to facilitate the multitude of operational requirements not only proves difficult to operate but challenges our modern ideas around security and makes maintenance almost impossible.
Sitting at home watching the Olympics 400m Women’s hurdles final live on NBC’s 4K HDR channel, home audiences were captivated by the sweat and effort displayed on screen with immersive sound of the runners’ feet hitting the track. Viewers thousands of miles away could be excused for thinking they had the best seat in the Japan National Stadium. The live 4K HDR broadcast of NBC’s primetime show throughout the Games were an extrasensory experience unlike any previous Olympics telecasts.
Although latency and resource coordination continue to challenge those considering cloud-based remote live production, the distributed architecture model is steadily gaining traction as a cost-effective alternate to hardware-based on-premise projects. To date this IT-centric architecture has not been deployed for high-profile productions like the Super Bowl or World Cup, but remote IP-video contribution, production and distribution has allowed second-tier sporting events to be televised globally whereas they might not be - due to cost and fully remote access - using traditional production methods.
