    UHD TV or UHD Monitor equipped with an HDMI input that supports HDCP v2.2. The DGA-6000 will not remove or alter the HDCP protection level of the Analyzer’s incoming video signals. The Analyzer will not change incoming signal formats or convert HDR video to SDR video. Therefore, the Monitor must be fully compatible with the video source driving the Analyzer input, else the Monitor may display the source video and the Analyzer information panes incorrectly, or not at all.

  • Page 48: Dga-6000 Motion Pattern Overview

    The DGA-6000 Motion Patterns can be used to evaluate the performance of UHD and HD TVs and video processors. Motion patterns are essential to evaluate 1080i, 480i, and 576i deinterlacing, and the scaling of HD (and SD) video formats to UHD (or HD) display formats.

  • Page 49: Accessing The Motion Patterns

    1) Select the Special Patterns Group - Press the Special button on the remote control, or use the Group button on the remote control, or the DGA-6000 front panel to advance to the Special Group. 2) Select the Motion Pattern – The Motion Pattern is the last pattern in the Special Patterns group.

Phase-Lock – When an odd number of lines of vertical movement per field is selected, horizontal pattern lines at the Nyquist frequency will always be displayed in the interlaced fields.

  • Page 53: Introduction To Video Motion Testing

    Introduction to Video Motion Testing Quantitative and Qualitative Testing Motion patterns are an essential tool for assessing video performance. The AccuPel DGA-6000 motion patterns are digitally generated in real-time using mathematical algorithms that produce perfectly uniform spatial frequency characteristics for the measurement and evaluation of displays and video processors. The...

  • Page 54: Nyquist Frequency

    For demonstration purposes, the DGA-6000 Slow Edge filter (a digital horizontal spatial filter – not available for 2160p motion patterns) can be temporarily enabled to observe the aliasing reduction effects of low-pass filtering, but be sure to disable the Slow Edge filter when using the motion patterns to actually test displays or processors.

  • Page 55: Spatial Frequency Response (Mtf) & Effective Resolution

    MTF curve is expensive and best done in a laboratory environment. However, the DGA-6000 motion patterns include sinusoidal signals that produce Circular and Hyperbolic Zone Plates, Linear Horizontal and Vertical Frequency Sweeps, and Horizontal and Vertical Resolution Wedges for visually determining where the spatial frequency response (MTF) begins to roll-off, and the effective (limiting) resolution for both static and moving images.

  • Page 56: Motion Pattern Notes

    An Example of Measuring Effective Resolution with and without Motion – Set the DGA-6000 Format to match the native resolution of the display. For instance, if the native display resolution is 1920x1080 pixels select 1080i to make interlaced video resolution measurements (with deinterlacing), or 1080p to make progressive video resolution measurements.

  • Page 57: Detail Discs

    DGA-6000. For instance, the square details in the detail disc patterns are precisely 1, 2, 4, or 8 black or white pixels in length vertically and horizontally, so they are physically slightly rectangular rather than square on screen for standard-definition video formats.
