Appeal No. 1998-0884 Page 6
Application No. 08/084,642
Claims 2, 8, 32, 43, 56, and 58 each specify in pertinent
part the following limitation: “selecting said frame-based
predictive encoding or said field-based predictive encoding as
a function of the predictive encoding that produces said
lesser quantity of data ....” In other words, the claims each
recite selecting between frame-based predictive encoding and
field-based predictive encoding based on which encoding
produces a smaller quantity of data.
The examiner fails to show a disclosure of the claimed
limitations in the prior art. Although Krause teaches
selecting between frame-based predictive encoding and field-
based predictive encoding, the selection is not based on which
encoding produces a smaller quantity of data. To the
contrary, the selection is based on which encoding is more
accurate. Specifically, the reference includes the following
passage.
[A]ccumulated errors from the respective frame and
field formatted paths are compared at a comparator
122, which provides an output signal at terminal 124
indicative of which path produced the least error
for a particular pair of pixel data blocks.
The output signal from the error evaluation and
selection components actuates switch 39 (FIG. 3) to
