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.
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.
Flexible Access is our way of responding to customer needs we see in the market. At a high level, it is about putting our customer experience first and foremost. In these uncertain times, our customers need to produce more stories, better.
PTP - as a precise network timing technology has been available for nearly two decades. It is already widely used in Telecommunication networks, Finance and Trading platforms, substation automation networks and many more industries. Every industry has its own demands such as target accuracy on the end nodes, or whether it should be used locally or via wide area connections. Furthermore, there is often the question of whether existing network components should be re-used or if they will be replaced.
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.
IP networks are delivering outstanding success for broadcasters, both in terms of scalable functionality and flexibility. And the recent NMOS suite of specifications is improving integration and control, with IS-06 and IS-07 accelerating the process.
