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

               The first introduction of the teaching value of the various            
          disclosed embodiments of Tanaka himself is found with respect to            
          Figure 3.  We make reference to the following locations as the              
          discussion in Tanaka relates to this first embodiment in Figure             
          3: column 14, lines 7 through 12; column 14, line 62 through                
          column 15, line 53 and column 16, lines 31 through 42.  The                 
          variance calculating portion 116 in Figure 3 is discussed                   
          beginning at the bottom of column 14.  The so-called fineness of            
          a respective block represented by the inputted television signal            
          is determined by this circuit.  Again, this indicates that the              
          computations occur on a block-wise basis on incoming, new signal            
          blocks for a new frame.  The referenced portion at column 15                
          indicates to us that in the context of the first embodiment in              
          Figure 3, it operates upon the prior art approach in prior art              
          Figure 1 by means of the first quantization step-size computation           
          portion 122 in conjunction with or feeding as an input signal 119           
          to the second quantization step-size computing portion 118.  The            
          variance calculating portion 116 also feeds this block 118 in               
          Figure 3.  Two outputs come from the block 118.  One is wrongly             
          argued by the examiner and correctly identified by appellant in             
          the early portion of the reply brief; this relates to the                   
          quantization class determinations represented by signal 121.
