Product Testing Report - Crestron NVX Platform

Summary

This testing procedure is specific to performing due diligence for the Micron AV program in order to formally recommend the Crestron NVX product line as an approved AV-over-IP matrix switching solution and add to the reference architecture.

Test Plan

Purpose

The purpose of the testing procedure is to validate sufficient video switching performance, EDID management, scaling performance, and general system feature set is sufficient for the Micron program. Based on research and discussions with Crestron sales and technical engineering contacts, we expect the testing procedures will validate a capable and robust switching experience and product line.

testing procedures

In general, the EDID management should function as follows:

1. Encoders set to EDID required for the source, typically 1080p/2CH or 2160p/2CH with 1080p support

2. Decoders should have scaling enabled to match native resolution of display.

This is the testing setup required:

1. Signal Routing - Using a Laptop HDMI output, connect to encoders and try various EDID settings (minimum should be 1080p/60/2CH and 2160p/30/2CH) and document resulting image on a scaled and non-scaled receiver/display. Document laptop screen and video at display. The goal of this test is to ensure we can ingest HD and UHD video.

   1. Signal paths required look like this:

   2. 1080p (source) -> 1080p (display)

      1. PASS

      2. 

   3. 1080p (source) -> 2160p (display)

      1. PASS

      2. 

   4. 2160p (source) -> 1080p (display)

      1. PASS

      2. 

   5. 2160p (source) -> 2160p (display)

      1. PASS

      2. 

2. Repeat test #1 using a USB-C laptop output with USB-C-to-HDMI active converter cable we use for Micron program.

   1. [Result of test]

      1. Similar to HDMI, USB-C showed that 4k can be routed, but there is an issue going from NVX360 to D200. E20 has no issue with USB-C to D200

      2. If the EDID wasn't good it would not work, but there were common EDIDs located that worked (e.g. DM Default).

   2. 
      

3. Test ability to capture an EDID from a connected display (UHD if possible) and assign to an input on an encoder. Test source behavior and video at display.

   1. [Result of test]

      1. Unable to take capture, but able to assign EDID to copy output on NVX 360. The E20 unable to perform this function.

   2. [Photo / screen shot supporting results]

      1. NVX 360 E20

4. Capture photos/screen shots of on screen menus, including scaler settings and EDID options showing HD and UHD resolution options.

   1. [Result of test]

   2. [Photo / screen shot supporting results]

      1. NVX 360 E20

5. Switching Performance - Switch sources to multiple displays using non-scaled and scaling outputs. scaling decoders should have scaling on. Here are the resolutions and switching test needs:

   1. (2) 1080p (sources) - Switched to 1080p display

   2. (2) 1080p (sources) - Switched to 2160p display

   3. (1) 1080p and (1) 2160p (sources) - Switched to 1080p display

   4. (1) 1080p and (1) 2160p (sources) - Switched to 2160p display

      1. [Result of test]

         1. Switching worked well, biggest issue is setting up compatible EDID for D200 decoder for 4K sources, some 4K EDID's caused issues on D200. Issue was consistently an EDID on input, not scaling to the output.

      2. [Photo / screen shot supporting results]

6. Test Audio de-embedding on the decoder by tying the 3.5mm output directly to a powered speaker or similar.

   1. [Result of test]

      1. De-embedding works, however, d200 is unbalanced 3 pin phoenix and nvx360 is balanced stereo (5-pin)

   2. [Photo / screen shot supporting results]

7. Being able to turn HDCP OFF ( and back on for some sources). This is required for laptop connections to be used as shared content with the zoom PC.

   1. [Result of test]

      1. PASS

   2. [Photo / screen shot supporting results]

      1. 

8. Confirm that inputs provide some sort of video sync detection so when a device is connected, the system updates a status and also sends out feedback via API (this is required to automate the source presentation, huge requirement for Micron).

   1. [Result of test]

      1. PASS

   2. [Photo / screen shot supporting results]

      1. 

9. Confirm that the outputs will be able to pass NO signal whatsoever when the routes to it are cleared. This can be turn ON/OFF in Crestron. This is used in broadcasting when audio needs to flow in the absence of video. The switcher in this case sends a black image to the output when cleared, to allow audio to go thru when there is no video. If this is the default and can not be turned off, it will NOT work for Micron systems. **Use a Micron supported HDMI-to-USB capture device used for Zoom Rooms for this test if possible.
