Patent number: 11297346Abstract: Disclosed herein are exemplary embodiments of innovations in the area of point cloud encoding and decoding. Example embodiments can reduce the computational complexity and/or computational resource usage during 3D video encoding by selectively encoding one or more 3D-point-cloud blocks using an inter-frame coding (e.g., motion compensation) technique that allows for previously encoded/decoded frames to be used in predicting current frames being encoded. Alternatively, one or more 3D-point-cloud block can be encoded using an intra-frame encoding approach. The selection of which encoding mode to use can be based, for example, on a threshold that is evaluated relative to rate-distortion performance for both intra-frame and inter-frame encoding. Still further, embodiments of the disclosed technology can use one or more voxel-distortion-correction filters to correct distortion errors that may occur during voxel compression.Type: GrantFiled: May 28, 2016Date of Patent: April 5, 2022Assignee: Microsoft Technology Licensing, LLCInventors: Philip A.

Patent number: 11223811Abstract: A transcoder resource retrieves content stored in a repository. The stored content can be encoded in accordance with a first encoding format. The transcoder resource transcodes the retrieved content into a second encoding format. To increase available capacity, the transcoder resource stores the content in the second encoding format as a replacement to the content encoded according to the first encoding format. The second encoding format can support a higher compression ratio than the first encoding format. Additionally, the transcoding can be performed as one of multiple tasks executed in parallel. In such an instance, during parallel processing, a content management resource interleaves execution of the main processing task and the background task of transcoding the content into the second encoding format. The transcoding task can be assigned a lower execution priority than one or more other tasks executed in parallel.Type: GrantFiled: December 17, 2018Date of Patent: January 11, 2022Assignee: Time Warner Cable Enterprises LLCInventors: Albert Straub, Edward P.
