Patent number: 10681368Abstract: A video predictive encoding device includes an input module to receive pictures forming a video sequence, and an encoding module to encode the pictures by either intra prediction or inter prediction to generate compressed picture data, and to packetize the compressed image data along with packet header information. The packet header information includes a picture type. The encoding module determines the picture type so as to uniquely indicate whether encoded picture data is used for reference in decoding of another picture.Type: GrantFiled: March 13, 2019Date of Patent: June 9, 2020Assignee: NTT DOCOMO, INC.Inventors: Junya Takiue, Choong Seng Boon, Thiow Keng Tan

Patent number: 10542287Abstract: An encoding target region in an image can be partitioned into a plurality of prediction regions. Based on prediction information of a neighboring region neighboring a target region, the number of previously-encoded prediction regions in the target region, and previously-encoded prediction information of the target region, a candidate for motion information to be used in generation of a predicted signal of the target prediction region as a next prediction region is selected from previously-encoded motion information of regions neighboring the target prediction region. According to the number of candidates for motion information selected, merging block information to indicate generation of the predicted signal of the target prediction region using the selected candidate for motion information and motion information detected by prediction information estimation means, or either one of the merging block information or the motion information is encoded.Type: GrantFiled: July 19, 2018Date of Patent: January 21, 2020Assignee: NTT DOCOMO, INC.Inventors: Yoshinori Suzuki, Junya Takiue, Choong Seng Boon, Thiow Keng Tan

Patent number: 10484699Abstract: A predictive coding system performs predictive encoding by determination of an optimum prediction mode from prediction methods for a pixel signal of a target block. A predicted signal is generated according to the determined mode, and a residual signal is determined. The residual signal and the optimum prediction mode are encoded to generate a compressed signal, which is decoded. The decoded signal is stored as a reconstructed picture sample. During encoding, a candidate prediction mode list is generated that contains elements of optimum prediction modes of previously-reproduced blocks neighboring the target block. A flag indicating whether the list contains an element corresponding to the optimum prediction mode is encoded, and an index to the corresponding element is encoded if the corresponding element is included in the list. The optimum prediction mode can be encoded based on identifying the elements in the list, unless no corresponding element appears on the list.Type: GrantFiled: July 31, 2018Date of Patent: November 19, 2019Assignee: NTT DOCOMO, INC.Inventors: Choong Seng Boon, Junya Takiue, Thiow Keng Tan

Patent number: 10477228Abstract: A video predictive encoding device can include an input device to implement input of pictures constituting a video sequence; an encoder to encode the pictures by intra-prediction or inter-prediction and to encode output order information of each picture and information about a picture type of each picture to generate compressed picture data. The compressed picture data includes a picture to serve as a random access point. The video predictive coding device can also include a reconstruction unit to decode the compressed picture data to reconstruct pictures; a picture storage unit to store one or more of the reconstructed pictures as reference pictures to be used for encoding of a subsequent picture; and a controller to determine the picture type and control the picture storage unit based on the determined picture type. The controller can label each picture as one of following three types: CRA picture, type-1 picture and type-2 picture.Type: GrantFiled: August 20, 2018Date of Patent: November 12, 2019Assignee: NTT DOCOMO, INC.Inventors: Choong Seng Boon, Junya Takiue, Akira Fujibayashi, Thiow Keng Tan
