High Dynamic Range

PQ and HLG Interoperability with Peter Wilson

HDR is the next major development in Ultra-HD/4K television, vastly improving contrast and detail to enhance the viewer experience.

Wilson dismissed some of the myths that have built up about the new technology: tube cameras and cathode ray tube televisions are not HDR; and the first innovators of this new technology provided charge-coupled image devices for post-tube cameras.

In fact, it was transfer knees and slope processors that compressed highlights and stopped bright detail from blowing out, providing better peak definition for standard television sets.

NAB 2015: To the Internet and Beyond

1. Why your TV should talk to your toaster: connected-TV and the 'internet of things'

One of the big draws at television technology shows such as NAB in Las Vegas is the "living room of the future", with its wall-filling, multi-image, interactive TV screen. Such "wallpaper displays" are still, largely, mock-ups, not demonstrations of real services.

But the "internet of things" (IoT) – the multiplication of connected devices, body-worn sensors and Cloud data services – could soon make such TVs a reality.
