Patent number: 11902505Abstract: A video decoding device, in the case where a video of the progressive format is inputted, processes a frame as a picture, in the case where a video of the interlace format is inputted, processes a field as a picture. A video decoding device performs display control corresponding to a format of the both video by analyzing display control information in display control information analyzer. The display control information includes sequence unit display control information which is commonly used in a display process of all pictures that belong to a sequence to be decoded and picture unit display control information which is individually used in a display process of a picture to be decoded. A second code string analyzer acquires each of the sequence unit display control information and the picture unit display control information from an extended information area in units of pictures.Type: GrantFiled: February 6, 2023Date of Patent: February 13, 2024Assignee: PANASONIC INTELLECTUAL PROPERTY CORPORATION OF AMERICAInventors: Kiyofumi Abe, Kazuhito Kimura, Hideyuki Ohgose, Hiroshi Arakawa, Koji Arimura

Publication number: 20240040152Abstract: An encoding method includes determining video format information, (i) setting each of all frames or all fields which are included in the video, as a picture, regardless of whether the video format is the interlace format or the progressive format, (ii) setting a POC indicating display order to each of all of the set pictures one by one, the POC being different each other, and encoding a picture to be encoded which is the frame or the field with reference to a picture previously encoded before encoding the picture to be encoded. In the encoding, the video is encoded with a syntax structure which is not dependent on the video format, the video format information is encoded in a header of a sequence which is a unit of the video, and the encoded bit stream is generated.Type: ApplicationFiled: October 16, 2023Publication date: February 1, 2024Inventors: Kiyofumi ABE, Kazuhito KIMURA, Hideyuki OHGOSE, Hiroshi ARAKAWA, Koji ARIMURA

Publication number: 20220229598Abstract: Service quality of a storage service provided by a storage cluster which can have a hetero configuration can be maintained. When a new node (a post-replacement or newly-added storage node) is added to the storage cluster, a storage system compares a spec of the new node with a spec of at least one existing node other than the new node. When the spec of the new node is higher than the spec of the existing node and a first volume (a volume associated with a priority higher than a first priority) exists in any one of the existing nodes, the storage system decides the new node as a migration destination of the first volume.Type: ApplicationFiled: September 8, 2021Publication date: July 21, 2022Applicant: Hitachi, Ltd.Inventors: Shinri INOUE, Akihisa NAGAMI, Koji WATANABE, Hiroshi ARAKAWA
