    摘要: An audio and video production system and method, including a video production control switcher; and one or more computers connected through a network and configured for controlling the video production control switcher. The system is further configured for at least one of defining looks, including shot templates, that correspond to particular settings on the production control switcher or settings of parts of the production control switcher; defining sequences of the looks or assigning individual looks to control elements on a computer of the computers; transmitting the looks across the network; and translating of a single look into one or more standard editor commands, and transmitting the commands to the production control switcher.

    摘要: A method, system, and device for generating a clean clipping signal α for a chromakey function or a video composition, including identifying background colors formed by a solid color background, shadows cast by still and moving subjects, a non-uniform reflection caused by spot lighting and non-flat backdrop or flaw wall, and translucent foreground objects, with a 3D volume in a 3D color space; determining parameters defining same by using a dirty alpha α; generating a clean clipping signal αshd background colors, and a clean clipping signal αtsl for translucency colors; identifying foreground colors formed by the still and moving subjects with a 3D volume in a 3D color space; classifying colors into transition colors; and generating an area map for mapping each pixel into background, shadow, translucent, foreground, and transition areas.

    摘要: A video production switcher includes at least one multi-level effects generator having at least two keyers and video signal mixer. A digital video processor unit is associated with each of said at least two keyers, the digital video processor operable to generate at least a two-dimensional effect, such as an over-the-should box effect.
