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 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)(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.
Claim(s) 19-20 is/are rejected under 35 U.S.C. 102(a)(2) as being anticipated by Zhao et al. (US 2022/0256174).
Regarding claim 19, Zhao discloses a non-transitory program storage device having encoded data representative of an image of a video (see fig. 1; e.g. see ¶ [0327]), the encoded data comprising: an indication specifying an absolute codeword value of a corrective value (e.g. see ¶ [0174], [0228]) for one or more chroma residual scaling parameters (e.g. see ¶ [0174]); and an indication specifying a sign of a corrective value (e.g. see ¶ [0174], [0028]) for one or more chroma residual scaling parameters (e.g. see ¶ [0174]).
Note: The claim discloses “a non-transitory program storage device having encoded data representative of an image of a video”. The claim then recites the content of the data. These data do not add any further structure or functional limitation to the “storage device having encoded data representative of an image of a video”. Hence, these data do not add patentable weight to the claim. It is recommended to either cancel the claim, change to a method claim or add a “non-transitory computer-readable medium storing a bitstream with stored instructions to decode the bitstream according to the method of ...” to consider the body of the claim along with incorporating all the limitations of claim 1 to have claim 19 in condition for allowance.
Regarding claim 20, Zhao further discloses wherein the indication specifying the absolute codeword value of the corrective value for one or more chroma residual scaling parameters and the indication specifying the sign of the corrective value for one or more chroma residual scaling parameters are part of an Adaptation Parameter Set (APS) in the encoded data (e.g. see ¶ [0187]).
Allowable Subject Matter
Claim(s) 1-18 is/are allowable.
The following is an Examiner’s statement of reasons for allowance: Claims 1, 6, 10 and 15 discloses a method comprising: decoding an indication specifying an absolute codeword value of a corrective value for one or more chroma residual scaling parameters; decoding an indication specifying a sign of a corrective value for one or more chroma residual scaling parameters; determining the corrective value for one or more chroma residual scaling parameters based on the indication specifying the absolute codeword value and the indication specifying the sign of the corrective value; obtaining one or more luma mapping parameters representative of a slope of a luma forward mapping function applied to a prediction of luma samples; determining one or more corrected luma mapping parameters by adding the corrective value of the one or more chroma residual scaling parameters to the one or more luma mapping parameters; obtaining one or more corrected residual scaling parameters by inverting the one or more corrected luma mapping parameters; scaling chroma residuals using one or more corrected residual scaling parameters; and decoding a video based on the scaled chroma residuals.
The closest prior art Zhao (US 2022/0256174) discloses chroma residual scaling parameters (e.g. see equation in ¶ [0174], and luma mapping parameters representative of a slope of a luma forward mapping function applied to a prediction of luma samples (see fig. 8) but fails to anticipate or render the above underlined limitation obvious.
Any comments considered necessary by applicant must be submitted no later than the payment of the issue fee and, to avoid processing delays, should preferably accompany the issue fee. Such submissions should be clearly labeled “Comments on Statement of Reasons for Allowance.”
Citation of Pertinent Art
The prior art made of record and not relied upon is considered pertinent to applicant's disclosure.
1. Shingala et al. (US 2020/0389648), discloses luma reshaping for chroma scaling.
2. Song et al. (US 2019/0320191), discloses chroma reshaping with dynamic range.
3. Su (US 2018/0124399), discloses dynamic range video reshaping.
