Calrad's new series of intelligent video scalers are a new way to think about converting, adapting and switching all types of video signals. The digital and analog HDTV converters and scalers provide a multitude of options from one format to another or digital to analog and analog to digital conversion. Rather than generating an output that is dependent on the input format. A video scaler is able to produce a converted image in a wide range of resolutions and refresh rates, completely independent of the original, incoming video format. Calrad's OSD (On Screen Display) interface is used in the converters and scalers to indicate a visual reference of signal type and available menu items, while providing adjustments of input and output signal resolutions, brightness, contrast, color, RGB, color channel gain, horizontal and vertical position and other vital settings of the unit.
