Test Pattern Options for Video Clarity’s ClearView Analyzers and ClearView Players

Visualizer™ Digital Video Test Pattern

The Visualizer™ test pattern offers a comprehensive way to evaluate more than 20 key parameters of video quality from a single screen. Users can easily identify processing errors throughout the digital signal chain.

The pattern is available as an uncompressed video sequence, pre-loaded on a ClearView Analyzer or ClearView Player product or as an upgrade via delivered ClearView Library folder applied to a specific ClearView system.

Visualizer™ Test Parameters That Verify Specific Video Characteristics

  1. Frequency response: Reveal upstream down conversions, scaling, and deinterlacing
  2. Compression fidelity: Measure and quantify compression levels in real time
  3. Subjective image fidelity: Perform a rapid check of system integrity
  4. Display gamma: Measure monitor gamma quickly
  5. Color conversion accuracy: Verify colorspace conversions
  6. Skipped frames: Detect repeated and dropped frames
  7. Chroma subsampling: Determine the Chroma subsampling being used (4:2:2, 4:2:0, 4:1:1…)
  8. Color matrix mismatch: Determine high-definition (709) and standard-definition (601) color space conversion errors
  9. White clipping: Determine if highlights are being blown out
  10. Chroma upsampling: Reveal how missing chroma samples are interpolated
  11. Black clipping: Reveal black clipping and accurately set monitor black level
  12. Bit depth: Detect 10-bit to 8-bit truncation
  13. Color phase and gain: Calibrate NTSC monitor color settings
  14. Field dominance: Definitively determine field order reversal
  15. Lip-sync: Measure and quantify the synchronization offset between audio and video
  16. Chroma motion error: Demonstrate incorrect processing of Chroma in interlaced 4:2:0 systems
  17. Noise: See how an encoder handles noise
