FOOTAGE COLLECTING/BROADCASTING DEVICE, FOOTAGE COLLECTING/BROADCASTING SYSTEM, FOOTAGE COLLECTING/BROADCASTING METHOD, AND RECORDING MEDIUM RECORDED WITH A PROGRAM

摘要

A footage collecting/broadcasting device includes a procedure, the procedure including: cyclically overwriting and storing input footage data in a storage section; periodically transmitting an existence confirmation request to an external device; setting, as a first start time to start protection of the footage data that excludes the inputted footage data from an overwrite target, a point in time reached by backtracking by a set time in cases in which the existence confirmation response from the external device is not detected a specific number of times.

1. A footage collecting/broadcasting device, comprising:
a processor configured to execute a procedure, the procedure including:
cyclically overwriting and storing sequentially input footage data in a storage section,periodically transmitting an existence confirmation request to an external device;detecting an existence confirmation response from the external device;setting a point in time reached by backtracking by a set time as a first start time to start protection of the footage data, the protection excluding the input footage data from an overwrite target, in cases in which the existence confirmation response from the external device is not detected a first specific number of times; andexcluding, from the footage data subject to the protection, the footage data input after the existence confirmation response has been detected a second specific number of times, in cases in which the existence confirmation response from the external device has been detected the second specific number of times after the protection of the footage data has started.
