So far in this series of articles the focus has been on the underlying requirements for successful audio over IP connectivity within a broadcast facility. The connectivity can be considered to be local; it is over a short distance, so the latency is low and it’s not a problem for the signal bandwidth to be high. In this situation the broadcaster has complete control over the network, including switch configuration and the routing of traffic over the network, so signal bandwidth and latency can be guaranteed.
Lithium batteries are all the rage on account of their low weight and high capacity. But how good are they really?

Modern broadcast facilities adopting video and audio over IP have found themselves working with thousands, or tens of thousands, of IP streams. Expecting humans to keep track of all these flows, monitor their quality and efficiently fault find is a virtual impossibility.
Compression is the ultimate enabling technology behind broadcasting. Without it, life would be very difficult indeed. In this new series, the whole topic will be explored at some depth.
In the final article in this series, we look at datasets, their importance and why GPUs are critical for machine learning.
Like a lot of new ideas in film and TV, high dynamic range pictures are easy to like. The fear is that they’re far harder to create. In reality, HDR isn’t necessarily a huge burden, certainly not in the way that stereo 3D can be. It’s often been possible to take well-shot images which were produced with no thought of an HDR finish, and make them available in HDR via a fairly straightforward re-grading process. Most people are aware of the truism that proper exposure is the cinematographer’s first responsibility, and we should probably hold on to that thought.
Of all the disruptive technologies that have emerged in the media and entertainment industry over the past few years, newsgathering and the fast turnaround production and delivery of breaking stories to many platforms is one of the most significant. Operating at the ‘speed of news’ is no longer a luxury but a necessity in today’s highly competitive landscape.
