Patent number: 10897655Abstract: To make it possible to easily use video data of raw data of a high frame rate input from a single-chip camera in a server system that is different from an AV server system in which an AV server itself is included. First AV clip data is obtained by performing a compression encoding process to raw data of a high frame rate input from a single-chip camera and is written in a storage. The raw data of the high frame rate is obtained by reading the first AV clip data from the storage and processing a compression decoding process on the first AV clip data, video data of a high frame rate is obtained by performing a demosaic process on the raw data, and second AV clip data is obtained by performing a compression encoding process on the video data and is written in the storage. The second AV clip data is read from the storage and transmitted to a second AV server system that is different from a first AV server system in which an AV server itself is included.Type: GrantFiled: April 11, 2017Date of Patent: January 19, 2021Assignee: SONY CORPORATIONInventors: Hideki Arai, Kaoru Urata, Mamoru Mizukami, Yasuhiro Ichinaka, Akira Itou, Kenta Abe, Yoshihide Fujimoto, Takashi Hoshi
