Specifications
The frame phase relationship between the SDI video stream and the analog
reference signal is established according to SMPTE RP 168-2002. This
defines the SDI video frame start occurring N pixel periods before the
frame start of the analog video reference signal. N is defined for each video
format in
Table 5 .
Electrical Length
Input to output delay: Default with zero user input delay
In delay mode or in genlock mode with zero input video delay with respect to genlock frame position:
Full-frame mode 1 frame period in all formats
Minimum delay mode ~ 300 pixel periods in all formats
Input to output delay: User input delay in pixel steps ranging from 1 to 2 frames
1
In delay mode or in genlock mode with any input video delay with respect to genlock frame position:
Full-frame mode 1 frame minus 5 lines to 2 frames minus 5 lines
2
Minimum delay mode ~ 300 pixels to 1 frame
Mechanical
Frame type 2000T1DNG or 2000T3NG Kameleon Frame
Environmental
Operating temperature Refer to Kameleon 2000 Frame specifications
Operating humidity 0 to 90%, non-condensing
1 The User input delay is specified as 1 full frame. plus one frame in pixels and lines. The Delay Wrap Position on the Frame
Sync web page roughly indicates what fraction of that last frame of adjustable delay is being used. Because the input video
delay with respect to genlock frame position can vary, the Delay Wrap Position with respect to User Input Delay will vary.
2
Full Frame Mode always has at least 1 frame minus 5 lines of electrical length.
