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.
Over the past year, as broadcasters and production companies have expended great effort to reconfigure their workflows and develop new ways of working amid strict safety protocols, so too have the manufacturers of the technology and systems they rely on.
In the fourth and final part of this series, we wrap up with an explanation on how PTP is used to support SMPTE ST 2110 based services, we dive into timing constraints related to using COTS (Commercial Off-The-Shelf) hardware, i.e.: servers.
In the previous two parts of this four-part series, we covered the basic principles of PTP and explained how time transfer can be made highly reliable using both the inherent methods IEE1588 provides as well as various complementing redundancy technologies. In this part, we look deeper into monitoring PTP systems.
In the first part of this four-part series we described the basic principles of the Precision Time Protocol. In part two, we investigate PTP redundancy, specifically for media networks.
Jackinabox is a unique Flyaway Gallery/ PPU designed by John Surdevan and Sam Gardner, a multicamera director and a computer vision software engineer. After working together for years and looking at how things could be improved, they began to customise their own suite of live production kit that harmonises industry standard systems with their own hardware and software. John Surdevan explains to The Broadcast Bridge how they have blended Blackmagic Design gear with the Raspberry Pi Compute Module to create a multi-touch vision mixer to help them and other production teams work more creatively, faster, smarter and more economically.
As the broadcasting industry is moving from a traditional SDI infrastructure towards the All-IP Studio providing a common frequency and – equally important – an absolute notion of time for all devices is now provided by the underlying infrastructure itself. In this four part series, Thomas Kernen and Nikolaus Kerö investigate the intricacies of PTP timing.
