a plurality of augmenting digital samples representing
augmenting data (caption frame) whereby the resulting sequence
of digital samples (col. 5, lines 17-21) can be converted to
an electrical signal." The examiner combines Coutta with
Beaulier for a suggestion to use time data for the caption
frame.
Appellant argues (Brief, page 65) that Beaulier mixes the
background and caption images to form a composite image,
whereas appellant keeps the two sets of data distinct for
separate display. Appellant further explains, as part of a
Donaldson analysis (Brief, pages 66-7), that his means for
augmenting the data involves a separate conversion of the time
data and the scene data into separate arrays of integers
stored in adjacent regions of the same memory. Appellant
discloses (Specification, page 13, lines 6-7) that the serial
bit stream representing the image is "augmented at the end by
digital codes that specify the date and time of arrival." In
contradistinction to appellant's method, Beaulier supplies
both background and caption data to a keyer 52 which "mixes
the background and caption images to generate video data
defining a composite image frame which is communicated to
