Data recording transmission device, data recording transmission method, and data recording transmission program

A data recording transmission method comprising:

• causing a controller that controls the recording of the data in the recording medium and the transmission of the data recorded in the recording medium to the external device through the network to:
• record management information of a file for transmission including unit data on a management table recorded in the recording medium when the recording medium interface records data which is a predetermined time or a predetermined size as the unit data in the recording medium;
• transmit the file for transmission to the external device through the network by the network interface;
• erase the management information of the file for transmission on the management table after transmitting the file for transmission and record management information of a file for recording including the unit data on the management table;
• and
• update the management information of the file for recording to management information obtained by combining new unit data with the unit data included in advance whenever the recording medium interface records the new unit data in the recording medium, record the management information of the file for transmission on the management table, and erase the management information of the file for transmission after transmitting the file for transmission.

A computer software product that includes a non-transitory storage medium readable by a processor, the non-transitory storage medium having stored thereon a set of instructions for performing recording and transmission of data, the instructions comprising:

• a first set of instructions of recording management information of a file for transmission including unit data on a management table recorded in the recording medium when the recording medium interface records data which is a predetermined time or a predetermined size as the unit data in the recording medium;
• a second set of instructions of transmitting the file for transmission to the external device through the network by the network interface;
• a third set of instructions of erasing the management information of the file for transmission on the management table after transmitting the file for transmission and recording management information of a file for recording including the unit data on the management table;
• and
• a fourth set of instructions of updating the management information of the file for recording to management information obtained by combining new unit data with the unit data included in advance whenever the recording medium interface records the new unit data in the recording medium, recording the management information of the file for transmission on the management table, and erasing the management information of the file for transmission after transmitting the file for transmission.
