Quantum Data 3D testing on 780 handheld test instrument for HDMI
The 780 is a battery powered, portable multimedia AV signal generator and analyser that can quickly check the HDMI digital ports on HDMI devices such as HDTVs, projectors, repeaters, AV receivers, players and set-top-boxes.
The 780 instrument’s 3D capabilities include features for testing both source devices and sink devices equipped with 3D. Users can select any of the HDMI 1.3 3D resolutions (timings) through the touch screen display.
For testing HDMI sink devices, the 780 can render a variety of standard 2D patterns and 3D bitmap patterns as well. Users can create their own 3D bitmaps from existing stereoscopic image pairs using Quantum Data’s free 3D bitmap conversion tool. When 3D video is transmitted from the 780, it also transmits the necessary 3D infoframe metadata in the HDMI vendor specific infoframe. In this way, an HDTV’s response to 3D metadata can be verified.

For testing HDMI 3D-capable source devices, the 780 parses the incoming 3D video and displays the left and right eye images on the 780’s built-in display. With the 780’s network analyser option, the 3D infoframe metadata and timing data, transmitted from the source device, can be examined as well.
Additional 3D-related enhancements are planned. More 3D format structures will be supported as well as the parsing and display of 3D related EDID data from a 3D-equipped HDMI sink.
The 780 combines versatility and portability with ease of use. Whether in the development lab or out in the field, the 780 is an ideal tool for investigating interoperability problems or conducting routine testing of sources and sinks. Existing 780 owners can download the 3D update for free.
