Appeal No. 96-0553 Application 08/020,993 The arguments on page 4 of the reply brief are also misplaced in the context of our explanation of our understanding of the teachings and interrelationships in Tanaka between the prior art Figure 1 quantization of a first quantization step- size computing portion to each of the respective embodiments in Figures 3 to 6. Appellant goes on to submit that even if one were to construe Tanaka’s first quantization step-size as corresponding to a previously coded block, such construction must be limited to a correspondence with an immediately preceding or adjacent block of coded video data. At oral hearing this understanding was focused upon to point out that the corres- pondence was with respect to an intermediately preceding block of the same frame. This understanding is not consistent with our understanding of the way each of the respective embodiments 1 to 4 operate in Figures 3 through 6 of Tanaka in conjunction with the respective portions of prior art Figure 1. Finally, we note that with respect to the Figure 6 embodiment, the discussion at column 32, lines 11 through 21 indicates that quantization occurs with respect to luminance signal data of a corresponding color coding block. From the artisan’s perspective, it is clear that for the overall system of Figure 6 to operate with initial quantization capabilities 10Page: Previous 1 2 3 4 5 6 7 8 9 10 11 12 13 NextLast modified: November 3, 2007
