A transmitting section divides a content recorded in a recording medium
into data of a predetermined size, reproduces the data, and transmits the
data to a receiving device. An erasing section erases the outputted data
recorded in the recording medium, when the data of the predetermined size
is transmitted to the receiving device. An EOB adding section adds an
EOB, which shows an end of transmission, to the data transmitted from the
transmitting section, when a power off signal is inputted during
transmission of data by the transmitting section. An EOB-added data
position storing section stores a recording position, on the recording
medium, of the data to which the EOB is added. Then, a power off control
section turns off a power of the device.
