Arguments
       dpy	      Specifies  the  display  screen  on which the Xv Server is to accept requests from Xv clients.  If the display option is not
		      specified, Xv uses the display screen specified by your DISPLAY environment variable.  The display  option  has  the  format
		      hostname:number.	Using two colons (::) instead of one (:) indicates that DECnet is to be used for transport.

       time	      Specifies the request timestamp.
