  • Publication number: 20250097444
    Abstract: A method of decoding video data performed by an electronic device is provided. The method receives the video data and determines a block unit from a current frame included in the video data. The method determines an extrapolation merge list of the block unit. The extrapolation merge list includes multiple extrapolation merge candidates. The method selects an extrapolation reference candidate from the extrapolation merge candidates for the block unit. Each of the extrapolation merge candidates includes multiple previous extrapolation parameters used to reconstruct a corresponding one of multiple extrapolation-reconstructed blocks. The extrapolation reference candidate is one of the extrapolation merge candidates. The method then determines an extrapolation prediction filter of the block unit based on the extrapolation reference candidate, and reconstructs the block unit based on the extrapolation prediction filter.

  • Publication number: 20250016343
    Abstract: A method of decoding video data performed by an electronic device is provided. The method receives the video data and determines a block unit from a current frame included in the video data. The method further determines a cross-component prediction (CCP) merge list of the block unit, including several CCP merge candidates of the block unit, and selects one of the CCP merge candidates to determine a prediction model and a filtering flag of the selected CCP merge candidate. The method then predicts the block unit using the prediction model to generate a prediction block of the block unit, determines, based on the filtering flag, whether the prediction block of the block unit is further filtered to generate a predicted block of the block unit, and reconstructs the block unit based on the predicted block of the block unit.

  • Publication number: 20250008083
    Abstract: A method of encoding video data is provided. The method determines a block unit of an image frame of the video data. The method determines, for the block unit, a first merge candidate list including multiple merge candidates, and identifies multiple merge subgroups from the first merge candidate list. The method determines multiple first cost values each corresponding to one of the merge candidates, and determines an arrangement of the merge candidates in each of the merge subgroups based on the first cost values. The method determines a second merge candidate list by selecting, from each of the merge subgroups, a first K merge candidates of the merge candidates ordered based on the arrangements. Then, the method selects one of the merge candidates in the second merge candidate list to predict the block unit and encodes one or more merge indices into a bitstream based on the selected merge candidate.

  • Patent number: 12069851
    Abstract: A transistor, a memory and a method of forming the same are disclosed. The transistor includes a gate dielectric layer (200) having an upper portion (200b) and a lower portion (200a). The upper portion (200b) is multi-layer structure having an increased thickness without changing a thickness of the lower portion (200a). In this way, gate-induced drain current leakage of the transistor can be mitigated at uncompromised performance thereof. Additionally, the upper portion (200b) designed as multi-layer structure having an increased thickness can facilitate flexible adjustment in parameters of the upper portion (200b). The memory device includes dielectric material layers (DL), which are formed in respective word line trenches and each have an upper portion and a lower portion. In addition, in both trench isolation structures (STI) and active areas (AA), the upper portion of the dielectric material layers (DL) has a thickness greater than a thickness of the lower portion.
