     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT  
       FIG. 1  is a pictorial view of a schematic structural diagram of a wireless virtual computer operating platform device of a preferred embodiment of the invention. As shown in  FIG. 1 , the wireless virtual computer operating platform device includes a main computer ( 3 ), a wireless transmission device ( 1 ), and a wireless virtual host computer ( 2 ). The main computer ( 3 ) is capable of providing a video signal and receiving at least the working signal of an operating unit ( 31 ) which can be a keyboard ( 31   a ) or a mouse ( 31   b ), and displaying on a display unit ( 32 ) which preferably is a liquid crystal screen, through processing.  
      The wireless transmitting device ( 1 ) is electrically connected to the main computer ( 3 ) and capable of receiving a video-audio signal provided by the main computer ( 3 ). The signal transmits off to form a wireless signal which after being received by the wireless virtual host computer ( 2 ), which preferably is a personal digital assistant (PDA), is decoded and displayed on a screen ( 23 ) which is preferably a liquid crystal screen.  
      A user ( 4 ) then operates the wireless transmitting device ( 1 ) and generates a corresponding control signal that is displayed on the screen ( 23 ) on the one hand and is received by the wireless transmitting device ( 1 ) on the other hand. Afterwards, the control signal is transmitted back to the main computer ( 3 ) to be processed and is displayed on the display unit ( 32 ).
