Four Channel Video Splitter, Model 6216 provides for the combination of four applied asynchronous video input into a single video output.  Formatting of the video display is accomplished via an RS-232 Port. The 6216 operates with input video signals that comply with RS-170, RS-170A or NTSC. The four inputs may be a mix of these formats and do not have to be synchronized. The display is formatted by the user via the RS-232 port to provide up to four horizontal stripes.  The stripe configuration is suited to applications where the main point of interest is the horizontal location of an event, such as weapon scoring systems. The individual displayed windows are formed by selecting a start line number and a stop line number for each of the four input video signals (A, B, C and D).  This allows the user to set each window to any size desired and to place them in any order.  The window size values are selected in increments of FOUR scan lines (i.e a number between 0 and 120 for NTSC video).

The user then sets the values that determine what portion of the input video is displayed in its corresponding window.  Values are entered that determine the amount of cropping from both the top and bottom of each input video.   These values are set in one scan line increments.  The first value sets the number of scan lines before the image starts displaying within the defined window.  The second value is the number of scan lines the video is active.  If the programmed window size is larger than the size of the assigned video segment, the unused portion will be black.  If there is no applied video to an input that is programmed to be displayed in a window, the segment will be blue.

If desired, the user may insert a line between the programmed windows.  This line is two scan lines wide and the color may be set to Black (0%), gray 25%, gray 75%, white (100%) or disabled.  The operator may also adjust the brightness, contrast, chroma and hue of each input video if desired.

 The included GUI provides full control of the 6216 or the user may write their own control software if the application requires embedding the 6216 in a system configuration.

GPS Synchronized Miniature Time Code Generator/Video Inserter, Model 6115G-8V2 provides an IRIG B time code output derived from GPS and inserts a time message into two independent video signals.  The time code output is synchronized with UTC time unless a time offset has been programmed.  A twelve channel GPS receiver automatically acquires all in-view satellites upon power up and locks an internal IRIG B time code generator to the GPS time reference.  If the GPS lock is lost the 6115G-8V2 will automatically switch to an internal clock and continue generating the output IRIG B signal.  No discernible change in the IRIG B output will occur due to this transition.  Additionally a battery backed up internal clock maintains time during power loss.  An external event may be time tagged by applying an Event Trigger to the Trigger Input.  The time of the event will be captured and stored until output via the serial port. The maximum event burst rate is 100KHz and the event buffer can store up to 127 events.

An Inserted video time message may be positioned at any one of fifteen locations in the video frame as selected by a front panel switch.  The character size is also selectable, again by a front panel switch.  The time message positioning and size selection is independent for each video channel. The 6115G-8 features a programmable time offset to convert the time from the GPS  receiver from UTC time to local time.  

The 6115G-8V2 has an asynchronous RS-232C port, which provides a means of configuring the unit, as well as reading the time, event, and location information.  The output messages for time/location and events are individually controlled.  The Time/Location message may be set to OFF or AUTO.  When set to AUTO, messages are sent at one second intervals.  The Event message may also be turned off, or may be set to respond only to a Query or set to send automatically until the event buffer is empty.

Included with the 6115G-8V2 is a CDROM containing a self-installing utility program for setting up the unit via a Graphical User Interface (GUI) from a Windows™ based computer via the COM port. The program will run on Windows 9x, 2000, NT, ME and XP operating systems
