The Extron Annotator is a high performance, hardware-based annotation processor for video and computer-video sources. It allows the presenter to draw, point, or add text to electronic presentation materials using a touchscreen and/or a keyboard and mouse. The Annotator supports all common digital and analog video formats, from composite video to high resolution DVI, optional HD-SDI, and RGB. Input video is scaled and made available in a variety of output formats, including analog RGB and Extron MTP Twisted Pair, as well as optional DVI, HD-SDI, or scan-converted video. The Annotator is ideal for applications that require the overlay of graphics and text within A/V presentations, including schools, law enforcement, medicine, telepresence, and live events.
