          Appeal No. 2001-1929                                                        
          Application 09/167,994                                                      


          as well as the Advisory Action at pages 4 and 5 of the answer               
          to jointly explain the examiner’s reasoning for the art rejection           
          of the claims on appeal is highly disfavored since it makes                 
          reference to more than one prior Office action.  Note MPEP                  
          § 1208.                                                                     
               Rather than repeat the positions of the appellant and the              
          examiner, reference is made to the brief and reply brief as well            
          as the answer for the details thereof.                                      


                                       OPINION                                        
               We reverse.                                                            
               As the title of Boyce reveals, his invention relates to                
          decoding both high and standard definition video signals                    
          utilizing the same video decoder.  As noted at the bottom of page           
          3 of the principal brief on appeal and throughout this brief,               
          Boyce discloses reducing the cost and complexity of such a                  
          decoder by reducing the amount of data processed for a high                 
          definition video signal, thus lowering the image quality of this            
          type of video signal to correlate substantially to that of a                
          standard video signal.  This is consistent with the end of the              
          abstract and is mentioned several times in the summary of the               
          invention                                                                   

                                          3
