Thereafter, steps S11 to S14 described above are repeatedly executed.
Step S12 (meta information response) and step S13 (meta information transmission) described above may be performed synchronously or asynchronously. When step S12 (meta information response) and step S13 (meta information transmission) are performed in synchronization, step S13 (meta information transmission) is executed every time step S12 (meta information response) is executed. On the other hand, when step S12 (meta information response) and step S13 (meta information transmission) are performed asynchronously, step S12 (meta information response) and step S13 (meta information transmission) are executed independently. In this asynchronous case, the vehicle information collection application device 40 temporarily holds the drive recorder ID “camera_01” and the imaging data file meta information received in step S12 (meta information response), and stores the information for one or more times. The drive recorder ID "camera_01" and the image data meta information received in step S12 (meta information response) are collectively transmitted to the vehicle information collection server device 50 in step S13 (meta information transmission).
