Six Channel HD-SDI Video Data Encoder, Model 6055C-6GHD is a six channel video inserter designed to receive and retransmit (reclocked and buffered) HD-SDI video compliant with SMPTE 259M, 292M and 424M. The product samples GPS or IRIG B time to within 10µsec of each EAV (equivalent to analog vertical sync) event and can overlay the captured time value at user programmable resolutions of 1 second to 100µsec in decade increments. It also can write a MISB compliant Microsecond Timestamp of this same sampled time on line 9 of the VANC data. Each channel independently auto-detects and decodes the imaging format permitting most SDI 480i, 720p or 1080i/p 24/1.001, 24, 25, 30/1.001, 30, 50, 60/1.001 or 60 fps to be connected without operator intervention. The time message and up to 3,920 ASCII characters may be inserted into the active video image, with the color and location selected by the user. The 6055C-6GHD may overlay a fixed boresite crosshair (3 sizes) or a movable crosshair (3 sizes). The movable crosshair is positionable in 1 pixel increments in X or Y, relative to the center pixel of the prevailing video format. The time reference is derived either from the internal GPS receiver or an external IRIG B time code. If the GPS or IRIG lock is lost the unit will automatically continue to run on an internal clock. The 6055C-6GHD includes a GPS Synchronized IRIG B122 and IRIG B002 Time Code Generator. The system may also be set to read a previously written MISB compliant Microsecond Timestamp and overlay the value onto the video of the same frame it is read.
