Appeal No. 1998-2557
Application No. 08/335,550
Representative claim 21 is reproduced as follows:
21. A computer-implemented process for encoding video
signals, comprising the steps of:
(a) applying a transform to a current region of a
current video frame to generate transform signals;
(b) generating quantized transform signal differences
using the transform signals and reference transform signals
from a corresponding region of a reference video frame;
(c) quantizing the transform signals to generate
quantized transform signals;
(d) encoding the current region as an inter encoded
region, if there are fewer non-zero quantized transform signal
differences than non-zero quantized transform signals; and
(e) encoding the current region as an intra encoded
region, if there are not fewer non-zero quantized transform
signal differences than non-zero quantized transform signals.
