Abstract

There is provided a communication control apparatus comprising connection means for connecting a storage medium that has a memory function for reading and writing data, and a wireless communication function for communicating with an external apparatus. Control means supplies a clock to the storage medium at a predetermined timing and controls the wireless communication function of the storage medium. Obtaining means obtains, after the storage medium is supplied with the clock by the control means, communication protocol information on a communication protocol with which the wireless communication function is compatible from the storage medium. Display means performs display according to the communication protocol information obtained by the obtaining means. The control means stops supplying the clock to the storage medium after the communication protocol information has been obtained by the obtaining means.

Claims

1-13. -13. (canceled)

14. A communication control apparatus comprising:

a connection unit configured to connect a storage medium that has a memory function for reading and writing data, and a wireless communication function for communicating with an external apparatus;

a control unit configured to supply a clock to the storage medium at a predetermined timing and control the wireless communication function of the storage medium;

an obtaining unit configured to obtain, after the storage medium is supplied with the clock by the control unit, communication protocol information on a communication protocol with which the wireless communication function is compatible from the storage medium; and

a display unit configured to perform display according to the communication protocol information obtained by the obtaining unit,

wherein the control unit stops supplying the clock to the storage medium after the communication protocol information has been obtained by the obtaining unit.

15. The communication control apparatus according to claim 14,

wherein the control unit further deactivates the wireless communication function of the storage medium after the communication protocol information has been obtained by the obtaining unit.

16. The communication control apparatus according to claim 14,

wherein, when start of communication using the wireless communication function is instructed, the control unit restarts supplying a clock to the storage medium, and activates the wireless communication function if the wireless communication function has been deactivated.

17. The communication control apparatus according to claim 14,

wherein the display unit displays a menu screen for selecting an external apparatus that serves as a communication partner, the menu screen including, as an option of a communication partner, an icon that indicates an external apparatus compatible with the communication protocol indicated by the obtained communication protocol information.

18. The communication control apparatus according to claim 17,

wherein the display unit displays the menu screen that does not include an icon that indicates an external apparatus compatible with a communication protocol with which the communication control apparatus is not compatible, among communication protocols indicated by the obtained communication protocol information.

19. The communication control apparatus according to claim 17,

wherein, if the wireless communication function of the storage medium is compatible with a plurality of communication protocols, the display unit decides an arrangement of the icons on the menu screen according to a priority order of the plurality of communication protocols.

20. The communication control apparatus according to claim 14,

wherein the storage medium is an SD memory card and the wireless communication function is a wireless LAN.

21. The communication control apparatus according to claim 14,

wherein the wireless communication function of the storage medium is compatible with at least one of Picture Transfer Protocol (PTP) and Digital Living Network Alliance (DLNA), as the communication protocol.

22. The communication control apparatus according to claim 14,

wherein an operation mode of the storage medium includes a memory mode and an input/output mode, and

the control unit stops supplying the clock by deactivating the input/output mode.

23. The communication control apparatus according to claim 22,

wherein the control unit activates the memory mode and the input/output mode at the predetermined timing.

24. The communication control apparatus according to claim 14,

wherein the predetermined timing is at least one of a timing at which the storage medium is connected to the connection unit, a timing at which the communication control apparatus transits into a playback mode, or a timing at which the storage medium is initialized.

25. A method for controlling a communication control apparatus including connection unit configured to connect a storage medium that has a memory function for reading and writing data, and a wireless communication function for communicating with an external apparatus, the method comprising:

supplying a clock to the storage medium at a predetermined timing and controlling the wireless communication function of the storage medium;

obtaining, after the storage medium is supplied with the clock in said supplying, communication protocol information on a communication protocol with which the wireless communication function is compatible from the storage medium; and

performing display according to the communication protocol information obtained in said obtaining,

wherein in said supplying, supply of the clock to the storage medium is stopped after the communication protocol information has been obtained in said obtaining

26. A non-transitory computer-readable storage medium on which a program is stored, the program causing a computer to execute the method according to claim 25.
