Abstract: Backup system and method that can determine a backup destination in consideration of disaster are provided. There are provided: a data acquisition unit 110 that acquires disaster information, network information, and node information; a replication group construction unit 130 that generates, based on the disaster information, and the like, replication group information including association information between a first node that stores original data and one or more second nodes that are candidates for backup destination of the original data, and saves the replication group information in a storage unit 120; a replication destination node calculation unit 140 that, when executing backup of the original data, calculates the second node as backup destination from the replication group; and a replication processing unit 230 that replicates and stores the original data into the storage of the second node.

Abstract: A front fork capable of reducing an unsprung weight of the arm-shaped front fork, optimizing rigidity, and improving appearance is provided. A front swing arm includes a left and right arm portions, and a bridge portion integrally connecting the left and right arm portions, a first lightening hole, a second lightening hole and a third lightening hole are provided in the arm portion, the first lightening hole, the second lightening hole and the third lightening hole are covered with a reflector provided to be exposed to an outer side surface of the arm portion from outside.

Abstract: Setting information is converted into a plurality of image patterns (22), and the plurality of image patterns (22) are displayed in time sequence according to a predetermined sequence. A camera device reproduces the setting information from image information (3) which the camera device acquires by capturing the displayed description to set the setting information thereto.

Abstract: A link table (28) showing a link relation between video data which are time reference data and log data which are number reference data is disposed. When the video data are deleted from a video recording ring buffer (23) or when the log data are deleted from a log recording ring buffer (26), a link data management unit (27) instructs either a number reference data recording and deleting unit (25) or a time reference data recording and deleting unit (22) to also delete the data which are the link destination of the deleted data with reference to the link table (28). Simultaneously, the link data management unit (27) deletes the link relation from the link table (28).

Abstract: A method transcodes an image in the form of an encoded input bitstream. The input bitstream includes quality layers, each quality layer includes a resolution levels, each resolution level includes components, each component includes precincts, and each precinct includes a packet partition location, a header length, and a body length. The input bitstream is decoded partially to obtain a structure of the encoded input bitstream. Coordinates of a region-of-interest in the image are specified, and progressive parameters are defined. The partially decoded input bitstream is then encoded according to the structure, the coordinates, and the progressive parameters to obtain an encoded output bitstream.
