  • Publication number: 20220094979
    Abstract: A method, computer program, and computer system is provided for coding video data. Video data including a reference view and a current view is received. A co-located block in the reference view is identified for a current block in the current view. A predicted block vector is calculated based on an offset vector between the current block and the co-located block, and a disparity vector between the co-located block and the reference block in the reference view. The video data is encoded/decoded based on the calculated predicted block vector.

  • Patent number: 11252434
    Abstract: Reconstructing a coded current picture for video decoding including decoding picture partitioning information corresponding to the current picture; determining whether padding is applied to sub-regions of the current picture using the picture partitioning information; based on determining that padding is not applied, decoding the sub-regions without padding the sub-regions; based on determining that padding is applied, determining whether the padding includes wrap-around padding using the picture partitioning information; based on determining that the padding does not include wrap-around padding, applying repetition padding to the sub-regions, and decoding the sub-regions using the repetition padding; based on determining that the padding includes wrap-around padding, applying the wrap-around padding to the sub-regions, and decoding the sub-regions using the wrap-around padding; and reconstructing the current picture based on the decoded sub-regions.

  • Patent number: 11166067
    Abstract: An approach for streaming a coded virtual reality (VR) video stream including receiving a segments of the coded VR video stream; storing the segments in a playback buffer; based on determining that a current playback time is within a threshold time of a playback time of a buffered segment, that a current duration of the playback buffer is larger than a threshold duration, and that a current bandwidth is larger than a threshold bandwidth, and that a current viewport is different from a previous viewport, storing at least one refined tile corresponding to the current viewport in the playback buffer; constructing a frame based on the buffered segment and the at least one refined tile corresponding to the current viewport; and decoding the coded VR video stream based on the constructed frame.

  • Patent number: 9984256
    Abstract: Apparatus and method for detecting unauthorized tampering with a data storage device having a housing and a memory. A first identifier value is stored on an external surface of the housing and a second identifier value is stored within the memory. The first and second identifier values are combined in a predetermined order to form a combined identifier value for which a digital signature is generated using a private key, and the digital signature is stored on the storage device. The digital signature, the first and second identifier values, and one or more dummy identification values are retrieved from the storage device and stored in a memory of a verification device, which combines the retrieved first and second identifier values in the predetermined order to generate a retrieved combined identifier value. The storage device is authenticated using the retrieved combined identifier value, the digital signature and a public key.

  • Publication number: 20170323121
    Abstract: Apparatus (400, 500) and method (200, 220, 240, 260, 280, 300) for detecting unauthorized tampering with a data storage device (100, 110, 140, 520). In some embodiments, the data storage device has a housing (112, 142) and a memory (192) supported by the housing. A first identifier value (202A, 222A, 242A, 262A, 282A, 306A) is stored on an external surface of the housing and a second identifier value (202B, 222B, 242B, 262B, 282B, 306B) is stored within the memory. A digital signature (210, 256, 296) generated in response to the first and second identifier values and in response to a private key (208, 254, 288) is stored on the storage device. Thereafter, the first identifier value is retrieved from the external surface of the housing and the second identifier value is retrieved from the memory. The storage device is authenticated using the retrieved first and second identifier values, the digital signature and a public key (228, 274, 312).
