          Appeal No. 1999-0089                                       Page 5           
          Application No. 08/454,076                                                  


          With these principles in mind, we consider the appellants'                  
          argument and the examiner's reply.                                          


               The appellants argue, "[i]t is not enough for Krause                   
          simply to provide four possible modes, two of which correspond              
          to Appellants' two modes.  Rather, Krause must provide some                 
          teaching of selecting either the first mode or the second mode              
          -- and this simply is not expressly or even impliedly                       
          disclosed."  (Reply Br. at 7.)  The examiner replies, "[w]hile              
          it is true that Krause et al employs two other modes (i.e.                  
          intra-frame prediction encoding with frame-based orthogonal                 
          transformation and inter-frame prediction with field-based                  
          orthogonal transformation), the present claims do not exclude               
          these other modes."  (Examiner's Answer at 6.)  We consider                 
          the argument and reply with respect to the following claims:                
               •    claims 18, 38, 40, and 42                                         
               •    claims 39 and 41.                                                 


                              Claims 18, 38, 40, and 42                               
               “[W]hen interpreting a claim, words of the claim are                   
          generally given their ordinary and accustomed meaning ....”
