Patent number: 11979603Abstract: Aspects of the disclosure provide methods, apparatuses, and non-transitory computer-readable storage mediums for video encoding/decoding. In a method, prediction information for a current block is decoded. The prediction information indicates a first intra prediction mode and a secondary transform index, based on which a secondary transform core is determined. A first transform coefficient block is de-quantized from the prediction information. A size of the first transform coefficient block is less than a size of the secondary transform core. A part of a second transform coefficient block is generated based on the first transform coefficient block and the secondary transform core. A size of the second transform coefficient block equals the size of the secondary transform core. A size of the part of the second transform coefficient equals the size of the first transform coefficient block. The current block is reconstructed based on the part of the second transform coefficient block.Type: GrantFiled: October 8, 2021Date of Patent: May 7, 2024Assignee: TENCENT AMERICA LLCInventors: Xin Zhao, Xiang Li, Shan Liu

Patent number: 11849144Abstract: Innovations for signaling state of a decoded picture buffer (“DPB”) and reference picture lists (“RPLs”). In example implementations, rather than rely on internal state of a decoder to manage and update DPB and RPLs, state information about the DPB and RPLs is explicitly signaled. This permits a decoder to determine which pictures are expected to be available for reference from the signaled state information. For example, an encoder determines state information that identifies which pictures are available for use as reference pictures (optionally considering feedback information from a decoder about which pictures are available). The encoder sets syntax elements that represent the state information. In doing so, the encoder sets identifying information for a long-term reference picture (“LTRP”), where the identifying information is a value of picture order count least significant bits for the LTRB. The encoder then outputs the syntax elements as part of a bitstream.Type: GrantFiled: June 27, 2022Date of Patent: December 19, 2023Assignee: Microsoft Technology Licensing, LLCInventors: Gary J. Sullivan, Yongjun Wu
