Gefen TV 1080p HDMI Signal Generator

The Gefen GTV-HDMI-SIGGEN is a TV 1080p HDMI Signal Generator which is a hand-portable, cost-effective testing tool that allows installers to locate and eliminate problems with HDTV Equipment and Displays, as well as calibrate equipment, in a quick yet sophisticated manner on-the-spot.  Besides video patterns, the Generator also supports 3 types of audio testing signal, one built-in sine wave, one external analog audio, and one external digital audio input through TOSlink. The GefenTV Signal Generator also works with Standard Definition or High Definition video resolutions.  You can use the on-panel buttons or download the Windows software application to perform advanced control, such as timing/pattern programming and the reading and writing of EDID (display identification data).

The GefenTV Signal Generator isn't just for finding troubles with specific video equipment. The Generator provides real-time testing of entire A/V configurations, eliminating snafus in minutes, saving costly labor. Ad-Hoc testing of SD and HD TV configurations often involves exchanging A/V components and/or ferrying equipment between locations. With the TV Signal Generator, these time-consuming practices can be avoided.

This device is HDCP (high bandwidth digital content protection) compliant, making it compatible with all HDTV content and displays. HDCP is a standard data encryption scheme encoded into the DVI signal to prevent videos from being copied. HDCP was adopted in 2004 by the entertainment industry. If an HDCP-encoded video source is connected to a HDTV display without the proper HDCP decoding mechanism, the picture is relegated to "snow" or a very low (480P) resolution. To avoid this situation the video source, the display and any device in between must be equipped with HDCP software key decoding devices.

The GefenTV Signal Generator includes an HDCP verification test (Pattern #39) which is useful for insuring that all devices in the video path are correctly passing the HDCP protocol.

How the Gefen Signal Generator Works:
Connect the HDMI output port of the GefenTV Signal Generator to your HDTV display. Power-cycle all equipment. Activate the On-Screen Display (OSD) Menu via the remote control and select the tests that you would like to perform. The easy-to-use onscreen menu system will guide you through the options and features. You can feed digital or analog audio into the Signal Generator rear panel in order to hear music while testing displays rather than hearing the default high-pitched audio test tone.

Note: This device is fully HDCP and HDMI compliant.
