Introducing the new Avenue Layering Engine for use in broadcast, live venues and presentation. With two, independent linear keyers, program/preset background transitions, and audio mixing and breakaway, it’s an agile and flexible solution to combining audio and video content. Inputs can be driven by SDI signals from cameras, remote feeds, character generators, graphic and stillstore systems, and video servers. The full range of SDI signals from SD to HD and 3G formats are supported. The Avenue Layering Engine has two independent overlay keyers. The keyers support linear, luminance and additive keying from a variety of video sources. In linear and additive modes, external key signals are faithfully passed to the overlay combiners with the option of user adjustments to fine-tune the effect with hi/lo clip. When operating as a luminance keyer, the key signal processor provides precise control over the clip and gain functions used to extract a self-key from the fill video.
