DETAILED ACTION
Notice of Pre-AIA or AIA Status
The present application, filed on or after March 16, 2013, is being examined under the first inventor to file provisions of the AIA .
Response to Arguments
Applicant’s arguments with respect to claims 1-3 and 5-20 have been considered but are moot because the new ground of rejection does not rely on any reference applied in the prior rejection of record for any teaching or matter specifically challenged in the argument. The removal of the term “based on the displacement vector” from the determining motion information step changes the scope of the claimed invention to now refer to conventional candidate list generation from reference blocks. Motion vector candidates are now simply those associated with reference blocks rather than derived based at least in part on a displacement vector associated with the current block as previously claimed.
The non-statutory double patenting rejection over U.S. Patent No. 12,167,019 has been withdrawn in light of applicant’s amendments.
Claim Rejections - 35 USC § 102
In the event the determination of the status of the application as subject to AIA 35 U.S.C. 102 and 103 (or as subject to pre-AIA 35 U.S.C. 102 and 103) is incorrect, any correction of the statutory basis (i.e., changing from AIA to pre-AIA ) for the rejection will not be considered a new ground of rejection if the prior art relied upon, and the rationale supporting the rejection, would be the same under either status.
The following is a quotation of the appropriate paragraphs of 35 U.S.C. 102 that form the basis for the rejections under this section made in this Office action:
A person shall be entitled to a patent unless –
(a)(1) the claimed invention was patented, described in a printed publication, or in public use, on sale, or otherwise available to the public before the effective filing date of the claimed invention.
Claims 1-3, 5-10, and 13-20 are rejected under 35 U.S.C. 102(a)(1) as being anticipated by Sun et al. (12,167,006).
Regarding claims 1, 7, and 16, Sun discloses a method for decoding video data using temporal motion vector prediction (TMVP), the method being executed by one or more processes, the method comprising:
obtaining a coded video comprising a coded current picture (done by receiver as the inverse of the encoding process, col. 2 lines 57-61),
determining a displacement offset, the displacement offset identifying a block in a reference picture associated with a current block in the coded current picture (col. 3 lines 50-63);
determining a motion information associated with the identified block, the motion information being used as a motion vector predictor (MVP) from a temporal motion vector prediction (TMVP) candidate (col. 3 line 64 – col. 4 line 11); and
decoding the coded current block using the motion information (performed by decoder, col. 3 lines 38-42).
Regarding claims 2 and 8, Sun discloses the method and apparatus of claims 1 and 7, wherein a displacement vector associated with the identified block indicates at least one respective position of at least one motion vector predictor in a temporal motion vector predictor candidate list (col. 6 lines 13-21).
Regarding claims 3 and 9, Sun discloses the method and apparatus of claims 1 and 7, wherein a displacement vector associated with the identified block indicates at least one respective displacement vector among a plurality of displacement vectors associated with respective candidates in a temporal motion vector predictor candidate list (col. 6 lines 13-21).
Regarding claims 5, 13-15, 17, and 19-20 Sun discloses the method, apparatus, and computer readable medium of claims 1, 10, 16, and 18 wherein the displacement offset indicates a motion vector difference with adaptive motion vector resolution techniques (conventional indexing using a table) (col. 1 line 66 – col. 2 line 4).
Regarding claims 6, 10, and 18, Sun discloses the method, apparatus, and computer readable medium of claims 2, 8, and 16 wherein the displacement vector has a displacement vector resolution in a specific number of samples (inherent, as a displacement vector must have a resolution of at least one sample).
Claim Rejections - 35 USC § 103
The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action:
A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made.
Claims 11 and 12 are rejected under 35 U.S.C. 103 as being unpatentable over Sun in view of Chuang et al. (2018/0098086) [Chuang].
Regarding claims 11 and 12, Sun discloses the apparatus of claim 8, but fails to specifically disclose a TMVP candidate list is reordered based on a template matching cost, said list generated using a pre-defined scan order based on a magnitude of the displacement vector.
In an analogous art, Chuang teaches this to be a conventional approach to generating motion vector candidate lists, fist scanning in ascending order based on relative distances (paragraph 0110) then reordering the candidate list after applying template matching to find the optimal cost (paragraphs 0199-0200).
It would have been obvious at the time of effective filing to a person of ordinary skill in the art to modify the apparatus of Sun to include a TMVP candidate list is reordered based on a template matching cost, said list generated using a pre-defined scan order based on a magnitude of the displacement vector, as suggested by Chuang, for the conventional and predictable benefit of quickly determining the best motion vector candidate during video coding.
Conclusion
THIS ACTION IS MADE FINAL. Applicant is reminded of the extension of time policy as set forth in 37 CFR 1.136(a).
A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
