DGA-6000 Motion Pattern Overview
The AccuPel DGA-6000 Pro Engineering Option adds a variety of Motion Patterns to the DGA-6000 Ultra-
HD Video Generator that can be used to evaluate the effects of motion processing in a display or standalone
video processor.
Video without motion is simply a collection of still pictures. Static test patterns are essential for calibrating
basic display parameters, but real-world video performance depends on how display technologies and video
processing algorithms handle motion.
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. They are also required to measure the effective
horizontal and vertical resolution, and the spatial frequency response, of UHD/HD displays, and to reveal
artifacts imposed on horizontal and vertical picture detail when using the smooth motion frame-interpolation
technologies that are found in flat panel displays and video projectors. The motion patterns will also reveal
many possible artifacts created by linear and non-linear video processing, including motion-induced
contouring, at user selectable motion rates and movement angles.
Motion Groups
The Motion Patterns are divided into six (6) Motion Groups – Circular Zone Plates, Hyperbolic Zone Plates,
Horizontal (H) & Vertical (V) Resolution Wedges, H & V Linear Frequency Sweeps, H & V Detail Discs, and
Cosine Balls. Each Motion Group includes patterns of varying types and sizes to accommodate standard-
definition and high-definition video formats. 70 Motion Patterns are included.
Motion Pattern Selection
All Motion Patterns are selected from the Generator Motion Pattern Menu, which is available when the
Motion Pattern is selected in the DGA-6000’s Special Group. The Motion Pattern is the last pattern in the
Special Group.
User Selectable Motion Rates
The horizontal and vertical continuous motion rates can be independently selected in pixels per frame (or
field) and lines per frame (or field) respectively. That also allows the user to select the on-screen angular
path of motion.
Film Cadence Motion
The field motion cadence for 480i, 576i, and 1080i formats can be selected as 1-1, 2-2, or 3-2. The former
produces native video camera interlaced-video motion, while the latter produces the film cadences used for
50 Hz and 60 Hz interlaced video respectively.
Active Motion Resolution/Frequency Cursors
Horizontal, vertical, and radial cursors can be enabled that ride on the moving patterns to provide real time
measurement of horizontal and vertical resolution and spatial frequency response as the user changes
motion rates. Cursor readout is selectable in resolution units of Lines/picture width and Lines/picture height
(TVL). Frequency units of Cycles/picture width, cycles/picture height, and % of Nyquist Frequency are
selectable.
Motion Pattern Formats & Colors
Motion patterns are available for all DGA-6000 2D video formats (except 2160p50/60), and for all 3D Frame
Packing video formats. The motion patterns are available in YCbCr 4:2:2, YCbCr 4:4:4, RGB-Video, and
RGB-PC grayscale, primary, and complementary colors.
