Publication number: 20240064314Abstract: A video image encoding device, in a first mode, variable-length-encodes a residual coefficient to generate a coefficient code string, outputs the coefficient code string and the header information in a state in which the header information is associated with the coefficient code string, in a second mode, directly uses a differential image as a coefficient code string without variable-length-encoding the differential image, and outputs the coefficient code string and the header information in a state in which the header information is associated with the coefficient code string.Type: ApplicationFiled: October 31, 2023Publication date: February 22, 2024Inventors: Hideyuki OHGOSE, Kiyofumi ABE, Hiroshi ARAKAWA, Tatsuro JURI, Kazuhito KIMURA

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
