The finite speed of light, and indeed of all communication has various impacts on broadcasting.
As engineers and technologists, it’s easy to become bogged down in the technical solutions that maintain high levels of computer security, but the first port of call in designing any secure system should be to consider the user and their interaction.
In the last article in this series, we looked at why integrated monitoring is a necessity in modern broadcast IP workflows. In this article, we dig deeper to understand what is new in IP monitoring and how this integrates with traditional workflows.
Video, audio and metadata monitoring in the IP domain requires different parameter checking than is typically available from the mainstream monitoring tools found in IT. The contents of the data payload is less predictable and packet distribution more tightly defined leading to the need to use specialist media stream centric monitoring tools.
Practically all communication, including broadcasting, relies totally on electromagnetic waves that may be radiated far and wide from transmitters or guided along wires, waveguides or optical fibers.
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.
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.
