Turning to Daum, we agree with the examiner that Daum
discloses skipping or repeating video frames when the video lags
behind the audio by a predetermined amount. In addition, we find
that Daum is directed to synchronizing audio and video data
during MPEG decoding, and that alternatively, the audio can be
delayed by a number of frames to allow the video to catch up
(col. 26, lines 22-24). Moreover, although Daum discloses a/v
playback in a fast forward mode (col. 19, lines 28-35), Daum
provides no explanation of how this will be carried out. Thus, we
find that Daum does not disclose the synchronization of sub-
pictures, and does not disclose how a decoding in a fast forward
mode will be carried out. In addition, we find that Daum is not
directed to solving the same problem as appellant, i.e.,
simultaneously decoding at high speed video and sub-picture data
by skipping the current display control sequence if the updated
system clock reference value is greater than the command
executing start time.
Turning to Tsukagoshi, we agree with the examiner that the
reference is directed to reproducing subtitles (sub-pictures) in
a fast reproduction mode. However, from our review of Tsukagoshi
we agree with appellant (reply brief, page 2) that “the subtitles
to be displayed are not the subtitles which would be displayed in
