          Application 08/167,415

          21 to p. 33, line 13).  Thus, the Figure 12 circuitry                       
          eliminated four 00 bytes, i.e., bytes C -C , which is equal to

          the number of bytes that represented adjusting data in the                  
          received encoded data.  In so doing, the circuitry also                     
          changed the identity of the bytes which represent the four-                 
          byte staffing start code, which was initially represented by                
          bytes C -C  in the received encoded data stream but then by

          bytes C , C , C , and C  in the modified data stream, which is2  3  8        9                                                     
          written into the receiving buffer 32 (Spec. at 33, lines 13-                
          16; p. 34, lines 12-14).                                                    
               The result of eliminating four of the 00 bytes prior to                
          storage of the data in the receiving buffer is that the                     
          variable length decoder 33 (Fig. 11(A)) is required to                      
          eliminate only three 00 bytes, i.e., synchronizing byte C  and              
                                                                   1                  
          bytes C  and C  of the staffing start code (Spec. at 34, lines2     3                                                              
          12-21).  This permits the encoded image data to be processed                
          effectively (Spec. at 33, line 22 to p. 35, line 2), i.e.,                  
          without causing a discontinuity in the displayed image.
