Description

  The present invention relates to an information processing apparatus, and more particularly, to an information processing apparatus capable of controlling a media player with a remote controller of a counter device.

  In recent years, a mobile phone as an information processing apparatus has not only a communication function by a telephone call but also an address book function, a mail function via a network such as a base station or the Internet, a browser capable of browsing a Web page, etc. In addition to the functions, multimedia functions such as a music control function that can listen to audio data and a function that can receive terrestrial digital broadcast waves, terrestrial digital radio broadcast waves, and FM radio broadcast waves are installed. It is becoming.

  For example, Bluetooth (registered trademark) is known as a wireless communication technology that can be applied to electronic devices. By using this Bluetooth wireless communication technology, audio data can be transferred from a portable information terminal such as a mobile phone or a portable music player to an opposite device such as a headset without using an audio cable.

  As profiles for transmitting audio data, for example, “Advanced Audio Distribution Profile (A2DP)” (Non-Patent Document 1) and “Generic Advanced Audio / Video Distribution Profile” (Non-Patent Document 2) are known. These are standards for performing streaming transfer of audio data in real time between devices connected via Bluetooth.

  For example, in portable information terminals such as mobile phones and portable music players, audio data is compressed in a format such as SBC (Sub Band Coding), MP3 (MPEG1 Audio Layer-3), or ATRAC (Advanced Transform Acoustic Coding) 3. Transfer in packets. On the other hand, an opposing device such as a speaker or a headset does not wait for all packets to be received and reproduces them simultaneously with reception of data. As a result, the user can listen to the sound from the portable information terminal, portable music player, etc. in an almost real time on the opposite device such as a speaker or a headset.

  Recently, as a technology for reproducing audio data (data in an audio file format) using Bluetooth, so that an arbitrary file can be identified and reproduced from a plurality of audio files recorded in a music reproduction device, A technique that can be operated from a mobile phone is known (for example, see Patent Document 1).

  For example, when audio data is transferred from a mobile phone to an opposite device such as a headset using Bluetooth, the audio data is transferred or reproduced by transmitting a command to the mobile phone using a remote controller provided in advance in the opposite device.・ Technologies related to AV remote control services for controlling stopping and the like have also been proposed. The specifications of the technology related to the AV remote control service are defined by the standard of “AVRCP (Audio / Video Remote Control Profile)” (Non-Patent Document 3).

The AVRCP defines a packet format for the AV remote control command, and does not define the interpretation or operation method of the remote control command. Therefore, the technology related to the AV remote control service depends on the implementation of a mobile phone or the like.
JP 2006-94448 A Advanced Audio / Video Distribution Profile (Bluetooth SIG) Generic Advanced Audio / Video Distribution Profile (Bluetooth SIG) Audio / Video Remote Control Profile (Bluetooth SIG)

  Recently, in the above-described AVRCP, a command for acquiring content attribute information indicating a content attribute by an opposing device has been defined. This content attribute information includes media player (MP: Media Player) settings and playback status (whether it is being played or paused), information about the currently played song (eg, song name, singer, etc.) Name, performance time, etc.).

Thus, for example, when a user operates a remote controller provided in the opposite device to transmit a content attribute information acquisition request from the opposite device to the mobile phone, the content attribute information is transmitted from the mobile phone to the opposite device. It has become possible to display content attribute information received by devices. In recent years, mobile phones have not only music control functions that allow them to listen to audio data, but also terrestrial digital broadcast waves and terrestrial digital radio broadcast waves. , And a function capable of receiving FM radio broadcast waves, etc. have been installed, and media players have application programs other than music players (for example, application programs for receiving terrestrial digital broadcast waves) ) Is also included.

  For example, in the case of an application program for receiving a terrestrial digital broadcast wave, unlike a music player, there is no music track, and in principle, content attribute information cannot be transmitted from a mobile phone to the opposite device.

  However, in the current AVRCP, a media player other than a music player is not considered. For example, when the media player is switched to an application program for receiving a terrestrial digital broadcast wave from the music player, the media player is then switched from the opposite device. In response to the transmitted request for acquiring the content attribute information, a simple error response is returned, and there is a problem that the content different from that of the media player currently used on the opposite device side is displayed. In such a case, some trouble may occur in the operation on the opposite device side.

  The present invention has been made in view of such a situation, and an information processing apparatus capable of displaying information suitable for a switched media player on an opposing device even when the media player is switched. The purpose is to provide.

  In order to solve the above-described problem, the information processing apparatus according to the present invention receives a remote control command transmitted from the opposite device via wireless communication, and analyzes the remote control command received by the reception unit. And a media player determination means for determining whether or not the remote control command analyzed by the analyzing means is a media player capable of acquiring content attribute information when the content attribute information acquisition request command is provided. When the media player determining means determines that the media player is not capable of acquiring the content attribute information, a generating means for generating a response command using information indicating that the content attribute information cannot be set, and generated by the generating means Send the response command sent to the opposite device via wireless communication Characterized in that it comprises a stage.

  In the information processing apparatus of the present invention, a remote control command transmitted from the opposite device is received via wireless communication, the received remote control command is analyzed, and the analyzed remote control command is a content attribute information acquisition request command If it is, it is determined whether or not the media player is capable of acquiring the content attribute information. If it is determined that the media player is not capable of acquiring the content attribute information, the content attribute information is set. A response command using information indicating that the request cannot be made is generated, and the generated response command is transmitted to the counterpart device via wireless communication.

  According to the present invention, even when the media player is switched, the content attribute information suitable for the media player after switching can be displayed on the opposing device.

Judge whether or not. The response command generation unit 26 generates an appropriate response command for the remote control command transmitted from the headset 2 according to the determination in the remote control command analysis unit 25. Further, the response command generation unit 26 generates an appropriate command to be transmitted to the headset 2 based on the determination result by the media player switching determination unit 28.

  The media packet transmission unit 27 generates media packets corresponding to various media players and data encoding methods, and transmits the generated media packets to the headset 2 via short-range wireless communication. The media player switching determination unit 28 views whether or not the media player controlled by the media player control unit 21 has been switched to another media player, for example, via the terrestrial digital one-segment radio receiving unit 17. It is determined whether or not the broadcasting station using the terrestrial digital one-segment broadcasting wave has been changed.

  Next, the media player control process in the mobile phone 1 of FIG. 2 will be described with reference to the flowchart of FIG. This media player control process is started when one of the media players is executed after the short-distance wireless communication unit 23 is activated by operating the input unit 13 by the user.

  In step S1, the media player switching determination unit 28 of the short-range wireless communication unit 23 determines whether the media player controlled by the media player control unit 21 has been switched to another media player. For example, when a music player among the media players is currently being executed by the media player control unit 21, for example, an activation of the media player executed by an application program when receiving a terrestrial digital broadcast wave is instructed. At this time, it is determined that the media player controlled by the media player control unit 21 has been switched to another media player.

  If it is determined in step S 1 that the media player controlled by the media player control unit 21 has not been switched to another media player, the remote command transmission / reception unit 24 of the short-range wireless communication unit 23 follows the control of the control unit 11. Then, it waits for reception of a remote control command transmitted from the headset 2 as the opposite device.

  In step S3, the remote control command transmission / reception unit 24, when the user operates the remote control 3 provided in the headset 2 as the opposite device, the remote control command (for example, transmitted from the headset 2 via wireless communication) (for example, Commands such as “Play”, “Pause”, and “Forward”) are received via wireless communication, and the received remote control commands are supplied to the remote control command analysis unit 25.

  In step S4, when the remote control command analysis unit 25 acquires the remote control command supplied from the remote control command transmission / reception unit 24, the remote control command analysis unit 25 determines whether or not the streaming operation is currently performed on the headset 2 (that is, the headset). 2) It is determined whether or not a streaming operation is being performed on another device other than 2 (for example, car navigation (not shown)).

  If it is determined in step S4 that the streaming operation is currently being performed on the headset 2, the remote control command analysis unit 25 interprets the acquired remote control command in step S5 by an interpretation method corresponding to each media player. Then, it is determined whether or not to respond to the remote control command transmitted based on the interpretation result. At this time, it is analyzed whether or not the received remote control command is a command such as “Play”, “Pause”, or “Forward”.

  In step S6, the remote control command analysis unit 25 determines whether the received remote control command is a content attribute information acquisition request command based on the analysis result. If it is determined in step S6 that the remote control command received is a command for requesting acquisition of content attribute information, the remote control command analysis unit 25 determines in step S7 that the current media player controlled by the media player control unit 21 is the current media player. Then, it is determined whether or not the media player is capable of acquiring content attribute information related to the content being reproduced.

  For example, when the current media player controlled by the media player control unit 21 is a music player, it is determined that the media player can acquire content attribute information regarding the content being played back. In the case of a media player executed by an application program when receiving a broadcast wave, it is determined that the media player is not capable of acquiring content attribute information regarding the content being played back.

  When it is determined in step S7 that the media player is capable of acquiring content attribute information related to the content being played back, the remote control command analysis unit 25 supplies a determination result to that effect to the response command generation unit 26. In step S8, the response command generator 26 reproduces according to the determination result supplied from the remote control command analyzer 25 (determination result indicating that the player is a media player capable of acquiring content attribute information related to the content being reproduced). A packet is generated using the content attribute information regarding the content in the content, and a response command that is a response to the remote control command of the content attribute information acquisition request transmitted from the headset 2 is generated.

  This content attribute information includes media player (MP: Media Player) settings and playback status (whether it is being played or paused), information about the currently played song (eg, song name, singer, etc.) Name, performance time, etc.).

  On the other hand, when it is determined in step S7 that the media player is not capable of acquiring the content attribute information regarding the content being played back, the remote control command analysis unit 25 supplies the determination result to the response command generation unit 26. To do. In step S9, the response command generator 26 reproduces according to the determination result supplied from the remote control command analyzer 25 (determination result indicating that it is not a media player capable of acquiring content attribute information related to the content being reproduced). A packet is generated using information indicating that the content attribute information relating to the content in the content cannot be set, and a response command (related to the content being played back) is a response to the remote control command of the content attribute information acquisition request transmitted from the headset 2 A response command indicating that the content attribute information cannot be set).

  The response command generator 26 supplies the generated response command to the remote control command transmitter / receiver 24.

  In step S10, the remote control command transmission / reception unit 24 acquires the response command supplied from the response command generation unit 26, and transmits the acquired response command to the headset 2 via wireless communication. As a result, it is possible to display on the display unit (not shown) of the headset 2 that the content attribute information relating to the content being reproduced cannot be set.

  On the other hand, if it is determined that the remote control command received in step S6 is not a content attribute information acquisition request command, the processes in steps S7 to S9 are skipped, and the process proceeds to step S10. In step S10, the headset 2 An appropriate response command is generated by the response command generation unit 26 with respect to the remote control command transmitted from the remote control command (for example, a command such as “Play”, “Pause”, “Forward”, etc.), and the generated response command is The command transmission / reception unit 24 transmits the data to the headset 2 via wireless communication. Thereafter, the process proceeds to step S1, and the processes after step S1 are repeatedly executed.

  If it is determined in step S4 that the streaming operation is not currently being performed on the headset 2, that is, the streaming operation is performed on another device other than the headset 2 (for example, a car navigation system (not shown)). If it is determined that the remote control command analysis unit 25 has performed, the remote control command analysis unit 25 interprets the acquired remote control command according to each media player in the same manner as when the streaming operation is performed on the headset 2 in step S11. It is interpreted by the method, and it is determined whether or not to respond to the remote control command transmitted based on the interpretation result.

  In step S12, the remote control command analysis unit 25 determines whether or not the received remote control command is a content attribute information acquisition request command based on the analysis result. When it is determined that the remote control command received in step S12 is a content attribute information acquisition request command, the remote control command analysis unit 25 supplies the determination result to the response command generation unit 26. In step S <b> 13, the response command generation unit 26 has not established a logical channel for controlling the service for transmitting the media packet to the headset 2 as the opposite device according to the determination result supplied from the remote control command analysis unit 25. Then, an error response command is generated as a response to the content attribute information acquisition request command transmitted from the headset 2, and the generated error response command is supplied to the headset 2.

  In step S14, the remote control command transmission / reception unit 24 acquires the error response command supplied from the response command generation unit 26, and transmits the acquired error response command to the headset 2 via wireless communication. Thereby, the error information can be displayed on a display unit (not shown) of the headset 2.

  Note that when it is determined that the remote control command received in step S12 is a command for requesting acquisition of content attribute information, an error response command is generated and transmitted. However, the present invention is not limited to this case. The response command itself may not be transmitted without generating a response command for the content attribute information acquisition request command.

  On the other hand, if it is determined in step S12 that the remote control command received is not a content attribute information acquisition request command, the remote control command (eg, “Play”, “Pause”, etc.) transmitted from the headset 2 in step S15. A response command suitable for a command such as “Forward” is generated by the response command generation unit 26, and the generated response command is transmitted to the headset 2 by the remote control command transmission / reception unit 24 via wireless communication. The Thereafter, the process proceeds to step S1, and the processes after step S1 are repeatedly executed.

  If it is determined in step S1 that the media player controlled by the media player control unit 21 has been switched to another media player, the media player switching determination unit 28 supplies the determination result to the response command generation unit 26. . In step S16, the response command generation unit 26 generates a command for instructing disconnection of the logical channel for the remote control based on the determination result by the media player switching determination unit 28, and generates the logical for the generated remote control. A command for instructing disconnection of the channel is supplied to the remote command transmission / reception unit 24.

  In step S17, the remote control command transmission / reception unit 24 acquires a command for instructing disconnection of the logical channel for the remote control supplied from the response command generation unit 26, and uses the acquired command via wireless communication. Send to headset 2. In step S18, the short-range wireless communication unit 23 disconnects the logical channel for the remote controller.

  Thereby, when the media player is switched, the initial setting can be indirectly urged to the headset 2 as the opposite device, and the information regarding the setting of the media player in the headset 2 can be initialized. Therefore, even if the media player is switched, it is possible to immediately recognize that the media player has been switched on the headset 2 side, and it is easy to initialize information relating to the settings of the media player in the headset 2. Can be done quickly. Thereafter, the process returns to step S1, and the processes after step S1 are repeatedly executed.

  In steps S16 to S18, a command for instructing disconnection of a logical channel for transport for transmitting a media packet, instead of generating and transmitting a command for instructing disconnection of a logical channel for the remote controller. May be generated and transmitted to the headset 2, and then the transport logical channel for transmitting the media packet may be disconnected. Thereby, when the media player is switched, the parameter information in the headset 2 as the opposite device can be indirectly updated, and the parameter information in the headset 2 corresponding to the media player after the switching can be used. Can be updated. Therefore, even if the media player is switched, it can be immediately recognized that the media player has been switched on the headset 2 side, and the parameter information in the headset 2 corresponding to the media player after the switching can be easily obtained. And it can be updated quickly.

  In the embodiment of the present invention, it is determined whether or not the current media player controlled by the media player control unit 21 is a media player capable of acquiring content attribute information related to the content being reproduced, When it is determined that the current media player controlled by the media player control unit 21 is a media player capable of acquiring content attribute information regarding the content being played back, the remote player command analysis unit 25 supplies In accordance with the determination result, a response command that is a response to the remote control command of the content attribute information acquisition request transmitted from the headset 2 is generated and transmitted to the headset 2, while being controlled by the media player control unit 21 Of media players are playing If it is determined that the media player is not capable of acquiring content attribute information related to content, information indicating that content attribute information related to the content being played back cannot be set in accordance with the determination result supplied from the remote control command analysis unit 25. It is possible to generate a packet by using it, generate a response command that is a response to the remote control command of the content attribute information acquisition request transmitted from the headset 2, and transmit the response command to the headset 2.

  Further, when a remote control command transmitted from the headset is received, it is determined whether or not a streaming operation is currently being performed on the headset 2 (that is, another device other than the headset 2 (for example, A determination is made as to whether or not a streaming operation is being performed for a car navigation system (not shown) or the like), and it is determined that a streaming operation is not currently being performed for the headset 2 (that is, the headset 2) Error response command that is a response to the content attribute information acquisition request command (if it is determined that a streaming operation is being performed on another device other than the other device (for example, car navigation (not shown), etc.)) Send or send a request to get content attribute information It is possible not to generate a response command.
