1. A footage collecting/broadcasting device, comprising:
- a processor configured to execute a procedure, the procedure including;
continuously, without stopping, and cyclically overwriting and storing sequentially input footage data in a region of a storage section that is outside of a region designated as a protected region;
periodically transmitting an existence confirmation request to an external device, the external device including another processor;
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 by designating a region of the storage section, in which the footage data that is input since the first start time is stored, as the protected region and to which continuously, without stopping and cyclically overwriting of the input footage data is permitted, while simultaneously protecting the protected region from being overwritten, in cases in which the existence confirmation response from the external device is not detected a first specific number of times; and
designating a region in which the footage data input after the existence confirmation response has been detected a second specific number of times as a non-protected region that is outside of the protected region, 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.

Abstract
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.

-
continuously, without stopping, and cyclically overwriting and storing sequentially input footage data in a region of a storage section that is outside of a region designated as a protected region; periodically transmitting an existence confirmation request to an external device, the external device including another processor; 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 by designating a region of the storage section, in which the footage data that is input since the first start time is stored, as the protected region and to which continuously, without stopping and cyclically overwriting of the input footage data is permitted, while simultaneously protecting the protected region from being overwritten, in cases in which the existence confirmation response is not detected a first specific number of times; and designating a region in which the footage data input after the existence confirmation response has been detected a second specific number of times as a non-protected region that is outside of the protected region, 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. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. A non-transitory recording medium storing a program executable by a computer to perform a process, the process comprising:
-
continuously, without stopping, and cyclically overwriting and storing sequentially input footage data in a region of a storage section that is outside of a region designated as a protected region; periodically transmitting an existence confirmation request to an external device, the external device including another processor; 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 by designating a region of the storage section, in which the footage data that is input since the first start time is stored, as the protected region and to which continuously, without stopping and cyclically overwriting of the input footage data is permitted, while simultaneously protecting the protected region from being overwritten, in cases in which the existence confirmation response is not detected a first specific number of times; and designating a region in which the footage data input after the existence confirmation response has been detected a second specific number of times as a non-protected region that is outside of the protected region, 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.
