Emerging standards are making the best of existing pixels. Understand the principles of HDR, learn how to build workflows to simplify production, and deliver the highest quality HDR pictures possible.
Many people and cultures celebrate special New Year dates. Organizations designate fiscal years. Broadcasters traditionally mark their new technology year mid-April, at annual NAB Shows. Old habits die hard.
In part 2 of this investigation, we look at why Apple’s new M1 processor benefits broadcasters.
In this final part of the series, an attempt will be made to summarize all that has gone before and to see what it means.
Apple’s M1-based MacBook Air, MacBook Pro, and Mac Mini have been the focus of computer news for the last half-year because of their surprisingly high-performance.
The #1 rule of live broadcasting is that things tend to fail at the worst possible time. The greater the ratings, the more likely something highly unlikely but mission-critical will fail, broadcast RF and wireless communication systems included. Count on it.
The requirement for a wide dynamic range to be provided economically is usually met by what is loosely called gamma, which is a non-linear transfer function having numerous drawbacks. However, there is an alternative form of what might loosely be called gamma, which is floating point.
The legacy gamma adopted in 709 and 240M has recently been supplanted by two more approaches to applying non-linearity to luminance, namely the Hybrid Log Gamma (HLG) system developed by the BBC and NHK and the Perceptive Quantizer (PQ) developed by Dolby.
Broadcasters are famous for adjusting to changing circumstances during live broadcasts without missing a beat. Live radio DJs roll with the punches. Live TV news reporters, newscast directors, engineers and technicians move or cut away as fast as possible. It comes with the territory and it’s in our DNA. The trick is to make surprises appear to be part of the show and carry on.
