          Appeal No. 96-0553                                                          
          Application 08/020,993                                                      

               After conducting a thorough study of the disclosed invention           
          and that as reflected in the claims on appeal in conjunction with           
          the respective positions of the appellant and the examiner and              
          the detailed teachings and suggestions of the applied prior art,            
          we will sustain the rejection only as to claims 7, 16 to 18, 27             
          and 28.   We, therefore, reverse the rejection of the remaining             
          claims 8 to 15 and 19 to 26.                                                
               From appellant’s brief and reply brief and the arguments               
          presented during oral hearing, it is apparent to us that the                
          focus of the dispute between the appellant and the examiner                 
          concerns only the following language of representative                      
          independent claim 7 on appeal:                                              
                    determining a correlation between one                             
                    of said plurality of blocks of one of said                        
                    frames of video data and a corresponding                          
                    block of a preceding frame of video data;                         
                    setting a quantization width in accor-                            
                    dance with said correlation.                                      
               Our study of prior art Figure 1 of Tanaka in conjunction               
          with the respective four separate embodiments set forth in this             
          reference for Tanaka’s contribution beginning at Figure 3 through           
          Figure 6 leads us to conclude that the above referenced language            
          of claim 1 is necessarily met by the teachings and suggestions as
