Patent number: 11265535Abstract: The present invention relates to an improved apparatus and method for harmonizing both Sign Bit Hiding (SBH) and Residual Sign Prediction (RSP) techniques in video coding. In order to improve coding efficiency, a list of transform coefficients, to which RSP is to be applied is prepared in advance of selecting a coefficient to which SBH is applied. Thereby, the RSP list can be populated in such a manner that the highest coding efficiency may be expected. Subsequently, one or more coefficients for applying SBH are selected so as not to be included in the list.Type: GrantFiled: September 4, 2020Date of Patent: March 1, 2022Assignee: Huawei Technologies Co., Ltd.Inventors: Alexey Konstantinovich Filippov, Alexander Alexandrovich Karabutov, Vasily Alexeevich Rufitskiy
