With over 4000 signals to distribute, transfer and route, the Eurovision Song Contest (ESC) proved to be this year’s showpiece for Riedel’s TDM based distributed mesh networked system MediorNet. Understanding the intricacies of such an event is key to realizing why TDM is such a powerful solution.
Broadcasters are no longer faced with the binary choice of going down the SDI or IP routes. The hybrid method of using TDM (Time Domain Multiplexing) combines the advantages of distributed networks with IP and SDI to deliver a fully integrated solution that helps broadcasters working across multiple technologies.
IP is well known and appreciated for its flexibility, scalability, and resilience. But there are times when the learning curve and installation challenges a complete ST-2110 infrastructure provides are just too great.
We live in fascinating times: increasingly, we live in the era of cloud-based broadcast operations.
In the beginning, there was television. And whenever people tried to make television programmes effective video signal monitoring was an essential pre-requisite.
As company mergers, acquisitions and extensive rights management agreements have become part of the new media landscape, it has created large multi-national conglomerates that span the globe. This in turn has revealed the need for IT networking technology and complex software orchestration that tie all of the disparate locations together and increase productivity across the company.
After years of trial and error designed to reduce operating cost and (more recently) keep crews safely distanced, remote production has found its niche in live production and will remain the de facto method for producing events over a distributed network infrastructure. However, a big hurdle left to overcome for successful deployment of such networked workflows is latency. In live production, video latency refers to the amount of time it takes for a single frame of video to transfer from the camera to a processing location (on premise or in the cloud) and back to the display—wherever that display might be.
A number of new production facilities are now being designed and built around the ST 2110 standard for video over IP, but the cost has been prohibitive for many others. The engineers at Diversified Systems Inc. (DSI), a veteran systems integrator, were challenged by this when it came to a recent project to add cameras to the recording studios of New York City’s renown Power Station.
