Description Support Documentation
The 780B Video Generator / Analyer is a battery-powered, portable video test instrument that enable you to conduct quick, on-site verification testing and troubleshooting of your HDMI system and analog video displays. The 780B supports all the features of the 780A including 300MHz on the HDMI Rx and Rx ports for testing of 4K Ultra HD HDMI 2.0 devices at 50/60Hz, but adds a larger screen (7 inches) for greater convenience in viewing analysis test results as well as a status bar on the bottom of the display for at-a-glance status on the HDMI Tx and Rx ports. Now supports testing of HDMI 2.0 devices including tests for 4:2:0 pixel encoding on sources and sinks, EDID emulation for testing HDMI 2.0 sources and distribution devices and tests HDMI 2.0 sinks with 21:9 formats. NEW! automated EDID test option enables automated testing of source devices' handling of a variety of EDIDs. Please check out the 780 Series Feature Comparison Chart to get a general understanding of the feature differences between the 3 models.

You can use the 780B instrument as a pattern generator for calibrating your high definition TVs. The 780B is equippped with a variety of standard patterns and formats including deep color and HDMI 3D formats.

Because the 780B instrument has both HDMI output and HDMI input ports, you can test your HDMI cables and systems with splitters, extenders and switches even when already installed on site using the Frame Compare feature.

The 780B instrument can also be equipped with the optional Auxiliary Channel Analyzer (ACA) utility for monitoring the DDC (HDCP and EDID) transactions and hot plug events. There are two ACA options, one for monitoring while emulating an HDMI source and/or sink and a second option for monitoring passively an HDMI network comprised of an HDMI source, repeater and sink. The passive monitoring option requires an extra hardware board with 4 HDMI ports.

The 780Bs' portability makes them ideal for your bench and for use in the field. A large 7 inch color touch display makes the 780B easy and convenient to use and when testing a source device you can view the incoming video image and metadata on the built-in LCD.
Standard Features (included with all options)

  • Battery powered for portability. Device is powered via internal batteries or externally via an AC charger.
  • Video pattern testing. Test a display's HDMI and analog component inputs with all the necessary standard timings to ensure that it can render video test patterns including deep color and HDMI 3D patterns. Over 25 video patterns supported. Add custom bitmaps. Create your own custom formats. Scroll bitmap patterns to test for motion artifacts.
  • HDMI audio testing. Send audio patterns, tones & noise through HDMI, SPDIF or Optical digital audio outputs including over HDMI 1.4 ARC channel for 780A. Program audio parameters such as sampling rate, bit depth and channels. Use a variety of audio formats including LPCM, Dolby, DTS and high bit rate audio formats such as Dolby TrueHD and DTS Master Audio.
  • HDMI analyzer for sources. Emulate a known-good HDMI sink device to analyze HDMI video and audio content from an HDMI source device with HDCP content protection. View the incoming video images and metadata from an HDMI source device on the LCD display even when content is protected with HDCP.
  • Installer Test Utility. Quickly diagnose HDMI interoperability problems through an automated and simplified interface. Run tests upstream toward the source, downstream toward the sink or test both upstream and downstream simultaneously with the "Link" test. The utility also enables you to test on both sides of a repeater.
  • Verify HDCP on repeaters and displays. Send HDCP encrypted video content to a downstream repeater (e.g. AVR) and/or sink (e.g. DTV). Check the authentication response from the sink.
  • Check Max HDCP HDMI devices. Check the number of HDCP devices an HDMI source supports during HDCP authentication.
  • Verify video timing. Verify the timing of an HDMI source. Compare against a known-good timing.
  • Verify video type. Verify the video type of an HDMI source. View AVI infoframe content.
  • Identify EDID problems. Run verification tests on the EDID of a sink device such as an HDTV or input of a repeater device. View the entire contents of the EDID of the sink device. Run portions of the EDID compliance test. Compare two EDIDS.
  • Verify an HDMI source's response to an EDID. Emulate the EDID of any HDMI sink device to verify that an HDMI source device responds properly to it. Store and retrieve multiple EDIDs for use in testing.
  • Verify audio data. Read the audio infoframes and audio sample packet headers including channel status bits from a connected HDMI source.
  • Check for CEC devices. Poll an HDMI installation for CEC devices.

HDMI Cable & Link Test Option
  • Verify HDMI cables. Run tests on HDMI cables. Test for pixel errors on multiple formats (resolutions) on the TMDS video and check continuity on the 5 volt, hot plug and DDC lines.
  • Prequalify HDMI networks (prior to installation) with Repeater Test. Verify HDMI networks comprised of cables, audio/video processors, extenders, switches, repeaters, etc. prior to installation. Test for pixel errors on multiple formats (resolutions) on the TMDS video and check continuity on the 5 volt, hot plug and DDC lines.
  • Test HDMI networks (once installed) with Frame Compare test. Verify HDMI networks comprised of cables, audio/video processors, extenders, switches, repeaters, etc. once installed. Test for pixel errors on the TMDS video.
Auto EDID Test
  • Specify a set of EDIDs for Testing. Specify a set of EDIDs to emulate in the 780B HDMI input port. These can be commercial EDIDs, EDIDs from Quantum Data EDID Library, custom EDIDs created using Quantum Data EDID Editor utility or known-bad "Test" EDIDs.
  • Verify Source Device Handling of EDIDs.Test verifies the incoming video type, timing, colorimetry, samplying and Video Identification Code and flags improper handling.
  • Auto EDID Test Report. A text report can be generated to allow sharing the results with colleagues or for later viewing.
HDMI Auxiliary Channel Analyzer (ACA) option - Two options available

  • Option 1 - Emulation monitoring of DDC transactions and hot plug events. Monitor the HDCP and EDID transactions on the DDC and also monitor hot plug related events while the 780 is emulating a known-good source device, a known-good display device or both.

  • Option 2 - Passive monitoring of DDC transactions and hot plug events (includes emulation monitoring option). Monitor the HDCP and EDID transactions on the DDC and also monitor hot plug related events while the 780 is passively monitoring and HDMI system comprised of multiple devices. Requires an additional hardware module with four (4) additional HDMI ports.
Custom Bitmap Test Pattern Pack Options

  • China Res Test Pattern Package - The ChinaRes test pattern is specified by the National Testing and Inspection Center for Radio and TV Products of China. The image pack includes both a standard definition aspect ratio (shown right) and a high definition aspect ratio. This test pattern is supported at: 1920x1080, 1280x720, 720x576 and 720x480 resolutions.

  • THX, LTD. Test Pattern Package - The THX test patterns enable A/V professionals to calibrate the displays on high-end 3D-capable HDTVs to match the same standards as those used in post-production facilities worldwide. Below are some of the THX test patterns included:

  • 3D convergence test patterns to align pixels for proper convergence
  • 3D crosstalk test patterns to determine level of 3D crosstalk
  • Color gamut 2D/3D primary & secondary color patterns to fine-tune colors & gamma
  • Picture performance pattern within THX Optimizer to verify accuracy of skin tones
  • THX box 2D/3D grayscale test patterns to accurately adjust white point and gamma
  • THX Optimizer test patterns to easily adjust brightness, contrast, color, tint, etc.
  • Uniformity 2D/3D circle patterns to determine luminance & chrominance screen uniformity
Imaging Science Foundation (ISF). Test Pattern Package - The ISF test patterns enable A/V professionals to calibrate the displays on modern high-end HDTVs. Below are some of the ISF test patterns included:

  • Geometry for testing geometry and resolution parameters
  • White Pluge for calibrating white level for dynamic range
