Any experienced master control operator or quality control manager will tell you that monitoring hundreds of feeds requires that each individual channel is delivered reliably, on time and to the exact location it was meant to go. When these signals are distributed over the public internet, strict protocols must be followed in order to ensure reliability and quality for every video service it supports.
The latest displays looking to gain a footing in the studio production arena are made from a technology known to mobile phone developers called organic liquid crystal displays (OLCD). It’s now being tested for dynamic set elements where video can be wrapped around and on top of a set piece. Other ultra-thin, shapeable technologies being discussed but not yet implemented include Flexible Open Frame OLED, In-Glass Wallpaper OLED and Ultra Stretch LCD signage displays.
To date, the explanations of gamma that are seen mostly restrict themselves to the voltage or brightness domain and very little has been published about the effects of gamma in the frequency domain. This is a great pity, because analysis in the frequency domain produces interesting results.
