Abstract
Various improvements for video production switchers are disclosed. In a user input module, a Link button is operable to link key functions with a user controllable input device. A multicolor lighting arrangement may be provided, and possibly calibrated, for illuminating each button of a switcher with a controllable color and/or intensity. In an improved Pulse-Width Modulation (PWM) scheme, a PWM output is dependent on a pseudo-random number and a threshold. A display on a keyer module may be used to provide indications of a key source and type currently associated with the keyer module. A switcher menu system may be enhanced by providing a first display for accessing a full menu system, and a second display for accessing at least a portion of the full menu system. In a modular switcher panel, a panel structure carries button modules, at least one of which is interchangeable without displacing other button modules.
