Information processing device, information processing method, program, and information processing system

An information processing device comprising:

• an acquisition control unit configured to control acquisition of first time-series data and second time-series data;
• a reception control unit configured to control reception of the first time-series data acquired by one or more other information processing devices and acquisition times of the first time-series data based on local time, which is time in the other information processing devices;
• and
• a synchronization control unit configured to determine, on the basis of the first time-series data acquired by control through the acquisition control unit and the first time-series data from the other information processing devices, start timing or end timing of recording of the second time-series data acquired by control through the acquisition control unit and the second time-series data acquired by the other information processing devices.

An information processing device comprising:

• an acquisition control unit configured to control acquisition of first time-series data and second time-series data;
• a transmission control unit configured to control transmission of the first time-series data and an acquisition time of the first time-series data based on local time, which is time in a device, to a first other information processing device;
• a reception control unit configured to receive start timing, which is synchronized with timing at which recording of the second time-series data acquired by one or more second other information processing devices is started and is based on the local time, or end timing, which is synchronized with timing at which recording of the second time-series data acquired by the second other information processing devices is ended and is based on the local time, from the first other information processing device;
• and
• a recording control unit configured to control start or end of recording of the second time-series data on the basis of the received start timing or end timing.

An information processing method comprising:

• an acquisition control step of controlling acquisition of first time-series data and second time-series data through an information processing device;
• a transmission control step of controlling transmission of the first time-series data and an acquisition time of the first time-series data based on local time, which is time in a device, to a first other information processing device through the information processing device;
• a reception control step of receiving start timing, which is synchronized with timing at which recording of the second time-series data acquired by one or more second other information processing devices is started and is based on the local time, or end timing, which is synchronized with timing at which recording of the second time-series data acquired by the second other information processing devices is ended and is based on the local time, from the first other information processing device through the information processing device;
• and
• a recording control step of controlling start or end of recording of the second time-series data on the basis of the received start timing or end timing through the information processing device.

A program for causing a computer of an information processing device to execute processing comprising:

• an acquisition control step of controlling acquisition of first time-series data and second time-series data;
• a transmission control step of controlling transmission of the first time-series data and an acquisition time of the first time-series data based on local time, which is time in a device, to a first other information processing device;
• a reception control step of receiving start timing, which is synchronized with timing at which recording of the second time-series data acquired by one or more second other information processing devices is started and is based on the local time, or end timing, which is synchronized with timing at which recording of the second time-series data acquired by the second other information processing devices is ended and is based on the local time, from the first other information processing device;
• and
• a recording control step of controlling start or end of recording of the second time-series data on the basis of the received start timing or end timing.

An information processing system comprising:

• a first information processing device;
• and
• a plurality of second information processing devices,
• wherein the first information processing device includes

• a synchronization control unit configured to determine, on the basis of the first time-series data from the plurality of second information processing devices, start timing or end timing of recording of second time-series data acquired by the plurality of second information processing devices, and
• wherein each of the second information processing devices includes
• an acquisition control unit configured to control acquisition of the first time-series data and the second time-series data,
• a transmission control unit configured to control transmission of the first time-series data and an acquisition time of the first time-series data based on the local time to the first information processing device, and
