5 AJA HDP2 HD-SDI/SDI to DVI-D Video and Audio Converter
VESA and CEA Timing
By default, the HDP2 will automatically output standardized VESA rate graphics where
appropriate when a computer resolution is detected, and standardized CEA rate video
when a video device, such as an HDTV is detected. Not all VESA rates are synchronous
to SMPTE standard video input rates. However, the HDP2 can be configured manually
by selecting an output frame rate that matches the incoming frame rate. By doing so,
enhanced timing signals will be generated that will be locked to the incoming video.
Note: Some monitors may not be able to handle some of these enhanced timing
modes. For best results, refer to the list of recommended monitors that have been
tested to lock at one or more of the user-selectable frame rates.
Motion Adaptive De-interlacing
Video displayed on DVI progressive display devices requires de-interlacing technology
to properly display the video from its native interlace format. HDP2 uses advanced
motion adaptive de-interlacing to predict motion in the video stream and output a
quality picture using spatial and temporal comparisons on individual pixels.
10-bit and Deep Color Support
HDP2 supports the HDMI 1.3a specification for Deep Color bit depths. In operation,
HDP2 can support Deep Color bit depths up to 30 bits/pixel (1.073 billion colors).
Video Scaling
As shown in the graphic below, the HDP2 will scale the input video to the best fit for a
given monitor and video input. In cases where the input video and the monitor are
already the same or similar, the HDP2 automatically turns off scaling. For example, a
1920 x1080 video and a 1920 x1200 monitor will not be scaled.
Note: The HDP2 also properly supports 16:10 and 5:4 monitors.
If the HDP2 scaling is set to 1:1 via the control panel, the input raster will be displayed
unscaled. This means that input rasters smaller than the monitor appear as a “floating”
image surrounded by black. For example, a 1280 x 720 image on a 1920 x 1200 monitor
only fills about 40% of the screen. Standard definition inputs unscaled on a 1920 x 1200
monitor only fill about 20% of the screen. This mode will only work when the input
raster is smaller than the monitor resolution.
