HELO Plus brings an exciting layouts feature, allowing multiple inputs to be combined into a single screen with a graphic element overlay. A layout enables the user to combine the SDI input and the HDMI input into a single output stream and then add a graphic (video + key) into that composite. The layout can have up to four layers, and their priority can be arbitrarily adjusted to suit the customer’s needs.
In addition to the layering engine, both the SDI and the HDMI layers can be arbitrarily downscaled and positioned anywhere in the frame. Effectively, each live video source can be used in its picture-in-picture (PiP) element.
The system also has an internal matte generator, which can be used as the background. In this way, the graphic can be keyed over the dual PiP images, which are “over” a flat matte background.
The system can accurately switch from one layout to another frame, allowing the user to “cut” between layouts during a streaming session. Layouts are stored in one of the 20 Presets, allowing users to recall all the parameters needed for a specific purpose. There are ten layouts stored in each preset so that the user can recall the show’s preset and switch between those ten layouts at will.
The graphics system is equally impressive - It stores 20 images in its internal, non-volatile memory.
