TPG-8 can be used to:

  • Assess the video monitors rendering quality, including video-frequency band; video monitor linearity, gamma correction, optimal contrast ratio and brightness;
  • Measure the recording and playback speed in digital video monitors, network video servers and computer video surveillance systems;
  • Control the signal quality of long cable commutation (adjust wave impedance parameters, far-end echoes, etc.);
  • Monitor the recording and playback qualities of video recorders and other devices for analog transmission and playback;
  • Evaluate vertical and horizontal image resolution, dynamic range and colour rendition after image digitisation under various standards (JPEG, MPEG-2, MPEG-4, Wavelet, JPEG 2000, etc.) and compression levels;
  • Estimate geometric distortions after video image digitisation;
  • Detect video signal dynamic range and level.
