In step S2104, the communication program 92 supplies a message indicating the registration to the terminal device 12 via the wireless network.

In step S1103, the communication program 152 receives the message indicating that it has been registered, which is transmitted from the server 11, and the processing ends.

FIG. 8 is a flow chart for explaining the determination process of the process corresponding to the button information, which corresponds to the process of step S2003 or the process of step S2007.

In step S11, the button information analysis program 93 determines whether the button information supplied from the communication program 92 corresponds to reproduction.

For example, when the button information includes the button number corresponding to the play button or the stop button of the operation unit 21, the button information analysis program 93 determines that the button information is based on the value stored in advance. It is determined whether or not reproduction is supported.

For example, when the operation section 21 has one button and the button information includes data indicating that the button has been pressed, the button information analysis program 93
Determines that the button information corresponds to reproduction when the server program 94 has not transmitted the still image, moving image, or audio data to the communication program 92.

When it is determined in step S11 that the button information corresponds to reproduction, the process proceeds to step S12, the button information analysis program 93 requests the server program 94 to transmit the data, and the process ends.

When it is determined in step S11 that the button information does not correspond to the reproduction, the process proceeds to step S13, and the button information analysis program 93 causes the button information supplied from the communication program 92 to correspond to the stop of the reproduction. Or not.

For example, when the button information includes the button number corresponding to the play button or the stop button of the operation unit 21, the button information analysis program 93 determines that the button information is based on the value stored in advance. It is determined whether or not the reproduction is stopped.

For example, when the number of buttons provided on the operation unit 21 is one and the button information includes data indicating that the button has been pressed, the button information analysis program 93
Determines that the button information corresponds to the stop of the reproduction when the server program 94 is transmitting still image, moving image, or audio data to the communication program 92.

When it is determined in step S13 that the button information corresponds to the stop of the reproduction, step S1
In step 4, the button information analysis program 93 requests the server program 94 to stop data transmission, and the process ends.

If it is determined in step S13 that the button information does not correspond to the stop of the reproduction, the processing of the request for the data transmission or the request for the stop of the data transmission is not necessary, so the processing ends.

As described above, the server 11 operates the terminal device 12
