Troubleshooting

My Stb-tester HDMI node is offline

images/Node-offline.png

The Stb-tester node must be able to access the Stb-tester web portal over the internet using HTTPS port 443. Make sure that your network configuration isn’t preventing this.

Diagnostic information about your network connectivity can be obtained by plugging a monitor into the Stb-tester node’s HDMI output. If you need further assistance, take a photo of the diagnostic screen and send it to support@stb-tester.com.

Live video doesn’t play in the web portal

The live video only works if you are accessing the web portal from the same local network as the Stb-tester node. If you are accessing the Stb-tester portal from a different network, select JPEG thumbnails instead.

The set-top box intermittently ignores infrared keypresses

  • Check the position of stb-tester’s infrared transmitter. This is a low-power transmitter (to avoid interfering with other set-top boxes in your test lab) so it has to be close against the set-top box’s IR receiver.

    Some set-top boxes are very sensitive to the placement of the transmitter; for example this image shows a set-top box that has a cylindrical shield extending around the IR receiver diode, so Stb-tester’s IR transmitter must be placed precisely in front of the diode:

    Using a torch (flashlight) can help you to see the position of the IR receiver behind the set-top box’s plastic case.

  • If you’re still seeing issues, send us your infrared configuration file to support@stb-tester.com.

OCR doesn’t understand my language

  • Install the necessary language pack by creating the file config/setup/setup with the following contents:

    #!/bin/bash -ex

# Install Danish language support for OCR:
sudo DEBIAN_FRONTEND=noninteractive apt-get install -y tesseract-ocr-dan

    …where “dan” is a three-letter ISO-639-3 language code.

    For more information about the config/setup/setup script see Customising the test-run environment.

  • Use the lang parameter when you call stbt.ocr and stbt.match_text —for example stbt.ocr(lang="dan")— or set the default language globally by setting lang in the [ocr] section of .stbt.conf.
