          Appeal No. 95-2855                                                          
          Application 08/075,338                                                      


          with this statement, but this argument misses the point.  Even              
          though memories 14-1 to 14-i are disclosed as being filled with             
          successive frames of data after the data is stored in the memory,           
          the availability of this data does not require that more than one           
          frame of data be output.                                                    
          Of more importance to the issue before us is the                            
          operation shown in Figures 2 and 3 of the application and                   
          described in the specification.  Figure 3 shows the prior art               
          synchronization operation wherein synchronization is not obtained           
          between the preroll point t0 and the lock-in point t1.  After               
          synchronization is achieved at point t1, the graph shows the time           
          codes linearly changing with time as the tape continues to play.            
          Figure 2 shows the operation of the invention.  It can be seen              
          there that a start signal Vs occurs before lock-in point t1, and            
          one of the memories is selected as the memory holding the desired           
          frame of data.  Although each of the memories in Figure 2 is                
          shown as continuing to linearly output time code data with                  
          respect to time, only one of the memories has been selected by              
          the comparator of Figures 1 or 4.  Once the comparison is made by           
          comparator 12, a single one of the memories is selected for read            
          out of the video data.                                                      



                                          7
