Appeal No. 2002-1510
Application No. 08/882,625 Page 2
1. A motion predictive inter-frame image signal compression
system, comprising
means for transforming image data, which includes a
plurality of groups of pictures, from one of a space domain and a
frequency domain into a plurality of data bands in the other
domain,
means for operating in said one domain to produce motion
vectors,
means for converting the motion vectors from said one domain
into motion vectors for one of said bands, said image data of
said one domain corresponding to a higher resolution than the
data of said one of said bands; and
means for allocating a target compressed-data bit rate to
pictures or blocks of pictures of a current group of pictures
according to a ratio of an amount of data generated during an
intra-frame coding of a prior group of pictures and an amount of
data generated during an inter-frame coding of said prior group
of pictures.
The prior art references of record relied upon by the
examiner in rejecting the appealed claims are:
Tourtier et al. 5,446,495 Aug. 29, 1995
(Tourtier)
Lee et al. 5,565,920 Oct. 15, 1996
(Lee)
Pecot et al.1 2 654 887 A1 May 25, 1991
(France Patent Application)
Claims 1-5 stand rejected under 35 U.S.C. § 103(a) as being
unpatentable over Pecot in view of Lee.
1 Although the examiner relies upon the summary of Pecot found in U.S.
Patent No. 5,446,495, to Tourtier, we rely upon the PTO translation of Pecot,
a copy of which is enclosed with the decision.
