HDR: Part 2 - Brightness Encoding

Dealing with brightness in camera systems sounds simple. Increase the light going into the lens; increase the signal level coming out of the camera, and in turn increase the amount of light coming out of the display. In reality, it’s always been more complicated than that. Camera, display and postproduction technologies have been chasing each other for most of the last century, especially since a period in the late 1990s…

Electricity: Part 3 - AC Systems

Here we look at alternating current (AC) systems and how generating AC often requires an intermediate step of converting to DC to improve the efficiencies of AC generators.

Camera Lenses: Through The Looking Glass, Part I

That lump of glass on the front of the camera is often taken for granted, but John Watkinson argues that choosing and using lenses wisely can make a big difference in captured image quality.

HDR: Part 1 - The State of HDR

Over the century or so we’ve been making moving images, a lot of improvements have been dreamed up. Some of them, like stereo 3D and high frame rate, have repeatedly suffered a lukewarm reception. Other things, like HD, and even sound and color, enjoyed more or less universal acclaim.

Virtual production was everywhere at NAB. Kicking things off, Mark Roberts Motion Control staged a demo at the main entrance to the LVCC.

At 2022 NAB Show Industry Demos Value Of 8K Production

It was in December 2018, during the Rugby World Cup hosted by Japan, that national broadcaster NHK began testing what it called its “Super Hi-Vision” 8K system, broadcasting images via satellite at up to 16x greater than that of HD—with a complementary 22.2-channel audio scheme. At the time NHK, working…

Information: Part 2 - Gaussian Distribution

Information can never be separated from its nemesis, which is uncertainty. The former is only possible by limiting the latter.

IP Security For Broadcasters: Part 8 - RADIUS Network Access

Maintaining controlled access is critical for any secure network, especially when working with high-value media in broadcast environments.

Thoughts On NAB 2022

NAB happened! Yes, footfall was inevitably down and there were fewer vendors exhibiting, but the show went on. And what a great success it was too.
