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 .
Claim 2 has been cancelled. Claims 1, 3-4 have been amended and are pending for examination.
Response to Arguments
Applicant’s arguments, filed 04/13/2026, with respect to the rejections of claims 1, 3-4 under 35 U.S.C. 13 have been fully considered and are persuasive. Therefore, the rejection has been withdrawn. However, upon further consideration, a new ground(s) of rejection is made in view of CHUANG (US 20190082191 A1).
Claim Rejections - 35 USC § 102
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)(2) the claimed invention was described in a patent issued under section 151, or in an application for patent published or deemed published under section 122(b), in which the patent or application, as the case may be, names another inventor and was effectively filed before the effective filing date of the claimed invention.
Claims 1, 3-4 are rejected under 35 U.S.C. 102(a)(2) as being anticipated by CHUANG (US 20190082191 A1).
Regarding claim 1, CHUANG teaches a method for decoding an image, the method comprising:
deriving motion vector resolution information of a current block based on affine motion compensation information (implementing Adaptive Motion Vector Resolution (AMVR) with affine motion compensation. [0058]);
deriving a motion vector difference of the current block based on the motion vector resolution information (AMVR provides a flexible scheme to reduce motion vector difference (MVD) transmission overhead by adaptively restricting MVD to integer pixel resolution. [0058]); and
deriving a motion vector of the current block based on the motion vector difference (the pixel resolution of the at least one non-zero MVD or at least one decoded motion vector is determined according to the AMVR flag. The decoded motion vector is derived by summing the MVD and a corresponding MVP in an affine candidate selected for the affine coded block. [0060]),
wherein the motion vector resolution information represents one of an integer pixel, a half pixel unit, a quarter pixel or a one-sixteenth pixel unit ( An AMVR flag is signaled for a coding unit (CU) or a prediction unit (PU) to indicate whether integer pixel resolution is used or fractional pixel resolution is used. [0058]),
wherein the motion vector resolution information is signaled in a bitstream (An AMVR flag is signaled for a coding unit (CU) or a prediction unit (PU) [0058]).
Regarding claim 3, CHUANG teaches a method for encoding an image, the method comprising:
deriving motion vector resolution information of a current block based on affine motion compensation information (implementing Adaptive Motion Vector Resolution (AMVR) with affine motion compensation. [0058]);
deriving a motion vector difference of the current block based on the motion vector resolution information (AMVR provides a flexible scheme to reduce motion vector difference (MVD) transmission overhead by adaptively restricting MVD to integer pixel resolution. [0058]); and
deriving a motion vector of the current block based on the motion vector difference (the pixel resolution of the at least one non-zero MVD or at least one decoded motion vector is determined according to the AMVR flag. The decoded motion vector is derived by summing the MVD and a corresponding MVP in an affine candidate selected for the affine coded block. [0060]),
wherein the motion vector resolution information represents one of an integer pixel, a half pixel unit, a quarter pixel or a one-sixteenth pixel unit ( An AMVR flag is signaled for a coding unit (CU) or a prediction unit (PU) to indicate whether integer pixel resolution is used or fractional pixel resolution is used. [0058]),
wherein the motion vector resolution information is signaled in a bitstream (An AMVR flag is signaled for a coding unit (CU) or a prediction unit (PU) [0058]).
Regarding claim 4, CHUANG teaches a method for transmitting a bitstream, the method comprising:
transmitting the bitstream generated by an encoding method (a video bitstream corresponding to compressed data including the current block in the current picture. [0011]), wherein the encoding method comprises:
deriving motion vector resolution information of a current block based on affine motion compensation information (implementing Adaptive Motion Vector Resolution (AMVR) with affine motion compensation. [0058]);
deriving a motion vector difference of the current block based on the motion vector resolution information (AMVR provides a flexible scheme to reduce motion vector difference (MVD) transmission overhead by adaptively restricting MVD to integer pixel resolution. [0058]); and
deriving a motion vector of the current block based on the motion vector difference (the pixel resolution of the at least one non-zero MVD or at least one decoded motion vector is determined according to the AMVR flag. The decoded motion vector is derived by summing the MVD and a corresponding MVP in an affine candidate selected for the affine coded block. [0060]),
wherein the motion vector resolution information represents one of an integer pixel, a half pixel unit, a quarter pixel or a one-sixteenth pixel unit ( An AMVR flag is signaled for a coding unit (CU) or a prediction unit (PU) to indicate whether integer pixel resolution is used or fractional pixel resolution is used. [0058]),
wherein the motion vector resolution information is signaled in a bitstream (An AMVR flag is signaled for a coding unit (CU) or a prediction unit (PU) [0058]).
Conclusion
Applicant's amendment necessitated the new ground(s) of rejection presented in this Office action. Accordingly, THIS ACTION IS MADE FINAL. See MPEP § 706.07(a). 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.
