• 4:3 aspect ratio - most commonly used for SDTV format, this aspect
ratio is almost square and is also referred to as full-frame or full-screen.
This setting should be used for displays with 4:3 aspect ratio.
When the source video and the display have different aspect ratios,
letterboxing or pillarboxing is implemented.
• Letterboxing refers to the black bars placed above and below the
picture to fill up the screen when the source material is in a
widescreen format and the display is set to a full-frame format.
• Pillarboxing refers to the black bars placed to the right and left of the
picture to fill up the screen when the source is in a full-frame format
and the display is in a widescreen format.
Optionally, use the Zoom Ratio parameter to reduce or eliminate any
black bars introduced by the aspect ratio of the source material.
Note For information regarding how the video setup, DVD setup, and display
settings interact to affect the display output, refer to the “Troubleshooting
Display Formats” section of the Chapter 4: Troubleshooting & Maintenance.
Color Space
The Color Space parameter identifies the color mapping format used for
the video output signal. Color space is a mathematical model that uses
numerical combinations of red, green, and blue to map the colors of the
video image. The available selections are:
• YCbCr 4:4:4 – provides a higher-resolution video output for those
higher sample rate formats available in some digitally formatted video
source materials .
• YCbCr 4:2:2 – standard compressed format common to DVDs and
digitally formatted video source materials.
• RGB Normal – provides a standard RGB color conversion to the
source video. This format is only available for HDMI outputs.
Typically, this setting is used with home theater displays, such as
plasma and front projections.
• RGB Expand – utilizes an expanded RGB color space definition to
provide higher color resolution. This format is only available for
HDMI outputs. Typically, this setting is used with PC-type displays,
such as DVI interfaces.
For optimal results, we recommend setting the Color Space
parameter to the format that matches the native format of the
video display. The color space conversion of the input source material is
then done by the Nº502, using its state-of-the-art video processing
technology, rather than by the video display, which may not have the
same processing capabilities. If necessary, refer to the documentation
included with the display to determine its native color space format.
