HDR is taking the broadcasting world by storm. The combination of a greater dynamic range and wider color gamut is delivering images that truly bring the immersive experience to home viewers. Vibrant colors and detailed specular highlights build a kind of realism into broadcast productions that our predecessors could only ever have dreamed of.
We’ve heard the hype, and I admit I’ve contributed my fair share. The iPhone is able to capture impressively sharp, high-resolution images that stand up to critical examination even when magnified and viewed on a 20-meter cinema screen.

In the UK we have Oxford v Cambridge. In the USA it’s Princeton v Harvard. The only difference is that one is a boat race and the other is computer architecture race.
This is the second instalment of our extended article exploring the use of the 5GHz spectrum for Comms.
Gain control in digital audio is essentially a numerical model of the same process in the analog domain.
