Annotator 300

HDCP-Compliant Annotation Processor with DTP Extension

The Extron Annotator 300 is a high performance, hardware-based annotation processor that allows a presenter to draw, point, or type over live presentations using a touch display, graphics tablet, or a keyboard and mouse. The HDCP-compliant Annotator 300 includes HDMI and DisplayPort inputs, a universal analog video input, and three simultaneous outputs including two HDMI and a DTP® twisted pair output. It also features advanced Extron video signal processing with a high performance scaling engine and fast, reliable switching. The DTP twisted pair output extends HDMI and bidirectional control signals to a DTP receiver over a shielded CATx cable up to 330 feet (100 meters). The Annotator 300 offers a wide range of annotation tools and controls, all easily accessible by the presenter using an intuitive on-screen GUI.

The Annotator 300 is ideal for applications that require the overlay of graphics and text within AV presentations, including law enforcement, medicine, education, telepresence, and live events.
