This VI merges the four synchronization bits (Hsync, Vsync, Csync, and FieldID) into the four least significant bits of a 16-bit input array. In order to merge the signal correctly, you need to pass the precalculated 16-bit data and the line number to the VI.

Line number specifies the video line where the synchronization signals are to be merged.
Input signal is the 16-bit (I16) data array containing the line data where the synchronization signals are to be merged.
error in is a cluster that describes the error status before this VI executes. If error in indicates that an error occurred before this VI was called, this VI may choose not to execute its function, but just pass the error through to its error out cluster. If no error has occurred, then this VI executes normally and sets its own corresponding error message. Using error in and error out clusters is a convenient way to check errors and to specify execution order by wiring the error output from one subVI to the error input of the next.
Output signal is the 16-bit (I16) data array containing the four synchronization bits.
error out is a cluster that describes the error status after this VI executes. If an error occurred before this VI was called, error out is the same as error in. Otherwise, error out shows the error, if any, that occurred in this VI. Use the error handler VIs to look up the error code and to display the corresponding error message. Using error in and error out clusters is a convenient way to check errors and to specify execution order by wiring the error output from one subVI to the error input of the next.
