Playing test signals on the Smart TV

Prerequisites

  • The Smart TV must have access to the test signals:
    • If a local web server is used, ensure that all test signals have been downloaded and stored in that server.
    • If the DISC website is used, ensure that the Smart TV has an Internet connection and is able to access the DISC website.
  • The USB flash drive containing the test application files must be connected to the Smart TV.
  • The playlist file has been successfully imported into the test application.

Procedure

  1. Start the test application.
    The application GUI appears.
  2. Navigate to and highlight the test signal you want to play in the Playlist panel by using the arrow keys on the remote control:
    • If you have successfully imported a playlist to the test application, only those selected test signals are displayed in the Playlist panel. Test signals are organized in hierarchical structure. Higher-level items are indicated by a folder icon next to them.
    • Information about a highlighted test signal is displayed next to the Playlist panel for approximately 15 seconds. To toggle the display on and off, press the info key on the remote control.
    • You can return to the parent-level playlist by pressing the Return key on the remote control.
  3. Play the highlighted test signal by pressing the Enter key on the remote control.
    The test signal being played has a triangle icon on its left side.
    • If playback of a test signal is successful, the Output panel displays Loading... and then the Current bitrate: # kbps, and the video plays back in the window in correct alignment with the audio.
      library_booksNote: The current version of LG Smart TV does not support displaying bit-rate information.

    • If playback of a test signal fails, the Output panel displays error messages.
      library_booksNote: Adverse behaviors during playback (such as audible pops, clicks, or muting) cannot be detected by the test application, and no error indication will display.

    • If network bandwidth fluctuates during playback, the Current bitrate: # kbps changes, indicating that audio track switching occurs to adapt to the current bandwidth.
