Patent number: 11095904Abstract: Approaches to selection of motion vector (“MV”) precision during video encoding are presented. These approaches can facilitate compression that is effective in terms of rate-distortion performance and/or computational efficiency. For example, a video encoder determines an MV precision for a unit of video from among multiple MV precisions, which include one or more fractional-sample MV precisions and integer-sample MV precision. The video encoder can identify a set of MV values having a fractional-sample MV precision, then select the MV precision for the unit based at least in part on prevalence of MV values (within the set) having a fractional part of zero. Or, the video encoder can perform rate-distortion analysis, where the rate-distortion analysis is biased towards the integer-sample MV precision. Or, the video encoder can collect information about the video and select the MV precision for the unit based at least in part on the collected information.Type: GrantFiled: June 24, 2020Date of Patent: August 17, 2021Assignee: Microsoft Technology Licensing, LLCInventors: Gary J.

Patent number: 11070823Abstract: Described tools and techniques relate to signaling for DC coefficients at small quantization step sizes. The techniques and tools can be used in combination or independently. For example, a tool such as a video encoder or decoder processes a VLC that indicates a DC differential for a DC coefficient, a FLC that indicates a value refinement for the DC differential, and a third code that indicates the sign for the DC differential. Even with the small quantization step sizes, the tool uses a VLC table with DC differentials for DC coefficients above the small quantization step sizes. The FLCs for DC differentials have lengths that vary depending on quantization step size.Type: GrantFiled: February 3, 2020Date of Patent: July 20, 2021Assignee: Microsoft Technology Licensing, LLCInventors: Chih-Lung Lin, Shankar Regunathan, Sridhar Srinivasan

Patent number: 11057628Abstract: Various embodiments of the present technology generally relate to encoding techniques. More specifically, some embodiments relate to encoding techniques for screen data. Intra block copy (IntraBC) using motion compensation within a frame (not between frames) is very useful for encoding data captured from screen. Unfortunately, this tool is not included in most of video coding standards, including the base version of HEVC (i.e., H.265). Various embodiments of the present technology utilize encoding techniques to simulate IntraBC with compliant syntax. For example, embodiments divide a high-resolution frame into smaller areas and then encode these areas independently as if these smaller areas were independent frames.Type: GrantFiled: April 24, 2020Date of Patent: July 6, 2021Assignee: Microsoft Technology Licensing, LLCInventors: You Zhou, Chih-Lung Lin, Ming Chieh Lee

Publication number: 20210203957Abstract: When encoding/decoding a current block of a current picture using intra block copy (“BC”) prediction, the location of a reference block is constrained so that it can be entirely within an inner search area of the current picture or entirely within an outer search area of the current picture, but cannot overlap both the inner search area and the outer search area. In some hardware-based implementations, on-chip memory buffers sample values of the inner search area, and off-chip memory buffers sample values of the outer search area. By enforcing this constraint on the location of the reference block, an encoder/decoder can avoid memory access operations that are split between on-chip memory and off-chip memory when retrieving the sample values of the reference block. At the same time, a reference block close to the current block may be used for intra BC prediction, helping compression efficiency.Type: ApplicationFiled: March 11, 2021Publication date: July 1, 2021Applicant: Microsoft Technology Licensing, LLCInventors: You Zhou, Chih-Lung Lin, Ming-Chieh Lee
