Description

  The present invention relates to a controller and a controller program for controlling a content reproduction apparatus.

A content playback system including a content playback device including a storage medium such as a flash memory capable of recording a music file and a headset is used. The content reproduction device reproduces the music file and transmits the music data to the headset using wireless transmission such as Bluetooth (registered trademark) . The headset receives music data and outputs sound from the headphones. A number of profiles such as A2DP, AVRCP, and HFP / HSP are defined in Bluetooth (registered trademark) .

A2DP (Advanced Audio
Distribution Profile) is a profile for wirelessly transmitting high-quality stereo sound. AVRCP (Audio / Video Remote Control Profile) is a profile for wirelessly transmitting a control command for controlling an audio device or the like. AVRCP has versions, and the types of control commands that can execute processing differ depending on the version. HFP (Hands-Free Profile) and HSP (Headset Profile) are profiles for making a monophonic voice call with a headset.

  The headset functions as a controller that controls the content playback device, and controls the content playback device using a profile such as AVRCP or HFP / HSP. Some content playback apparatuses support HFP / HSP but do not support AVRCP. Such a content playback apparatus needs to control the content playback apparatus by transmitting control audio data from the headset to the content playback apparatus using HFP / HSP instead of AVRCP. That is, the user utters a sound for controlling the content playback device toward the microphone of the headset (for example, when the content playback device plays a music file, the user utters a sound such as saisei or play toward the microphone). The voice input to the microphone is transmitted to the content playback apparatus using HFP / HSP.

  Similarly, some content playback apparatuses support AVRCP in addition to HFP / HSP, but cannot execute processing corresponding to some control commands of AVRCP. Therefore, when the content playback apparatus is controlled by an AVRCP control command that is not supported by the content playback apparatus, the content playback apparatus from the headset by voice input to the user's microphone using HFP / HSP instead of AVRCP It is necessary to transmit audio data for control to the content reproduction apparatus.

  Here, instead of using the AVRCP control command, when audio data for control is transmitted from the headset to the content reproduction apparatus by audio input to the user's microphone using HFP / HSP, in a noisy environment, Since the microphone collects noise, it is difficult to normally control the content reproduction apparatus. Also, in a public place, it is considered very embarrassing and resistance for the user to speak the voice for controlling the content playback apparatus toward the microphone instead of the AVRCP control command.

It is a figure which shows the control command which the reproducing | regenerating apparatus 200 respond | corresponds.

  Hereinafter, preferred embodiments of the present invention will be specifically described with reference to the drawings. However, the present invention is not limited to these embodiments.

FIG. 1 is a schematic block diagram showing a content reproduction system according to a preferred embodiment of the present invention. The content playback system includes a headset 100 and a content playback device (hereinafter simply referred to as a playback device) 200. The headset 100 and the playback device 200 can be connected to each other according to an arbitrary communication standard such as Bluetooth (registered trademark) . The playback device 200 plays back the music file recorded by itself and transmits the played music data to the headset 100 via Bluetooth (registered trademark) . The headset 100 receives the music data transmitted from the playback device 200 and outputs sound from the headphones. The headset 100 functions as a controller that controls the playback device 200.

As described above, profiles such as A2DP, AVRCP, and HFP / HSP are defined in Bluetooth (registered trademark) . The playback device 200 does not support AVRCP but supports A2DP and HFP / HSP, and supports A2DP, AVRCP, and HFP / HSP, but some control commands of AVRCP There are those that cannot execute processing in response to.

  The headset 100 stores a control audio file corresponding to the AVRCP control command in advance in the ROM. When an instruction to control the playback apparatus 100 is input by a user operation, the headset 100 transmits a control command corresponding to the input instruction instead of transmitting an AVRCP control command corresponding to the input instruction to the playback apparatus 200. The audio file is read from the ROM and reproduced, and the reproduced audio data is transmitted to the reproducing apparatus 200 using the HFP / HSP to control the reproducing apparatus 200. Therefore, the playback apparatus 200 can be controlled using HFP / HSP without the user having to utter sound for controlling the playback apparatus 200 toward the microphone.

  As shown in FIG. 1, the headset 100 generally includes a CPU 1, a RAM 2, a ROM 3, a communication unit 4, a playback unit 5, headphones 6, a microphone 7, and an operation unit 8. The CPU 1 controls each part of the headset 100 based on an operation program of the headset (controller) stored in the ROM 3.

  The ROM 3 stores a control audio file in advance. The control audio file is a file in which audio corresponding to an instruction to control the playback device 200 input in response to a user operation is encoded with a predetermined compression format and a predetermined bit rate. When an instruction to control the playback apparatus 200 is input by a user operation, a control audio file corresponding to the input instruction is read from the ROM 3 and played back, and transmitted to the playback apparatus 200 using HFP / HSP. Is done.

The communication unit 4 is connected to and communicates with the communication unit 18 of the playback device 200, and transmits and receives various control commands, control audio data, music data, and the like to and from the playback device 200. In this example, the communication unit 4 is a Bluetooth (registered trademark) wireless transceiver. The playback unit 5 plays back the music data received by the communication unit 4 from the playback device 200 (for example, decoding, D / A conversion, volume adjustment, amplification, etc.), and outputs sound from the headphones 6. The microphone 7 collects the voice uttered by the user and supplies it to the CPU 1.

  The operation unit 8 receives an instruction based on a user operation for controlling the playback device 200, and is an operation button or the like provided on the casing of the headset 100. As instructions based on user operations, for example, as shown in FIG. 2, “play”, “stop”, “playback state acquisition”, “track up / down”, “fast forward / fast reverse”, “repeat setting”, “ Random playback setting "exists.

  The CPU 1 reads out the control audio file corresponding to the instruction based on the user operation in accordance with the user operation for controlling the playback device 200 and causes the playback unit 5 to play back the control voice data that has been played back via the communication unit 4. To the playback device 200. When an instruction based on a user operation is input, the CPU 1 transmits an AVRCP control command corresponding to the instruction to the playback device 200, and the first mode for controlling the playback device 200 and an instruction based on the user operation are input. In this case, instead of the AVRCP control command, the control audio file corresponding to the instruction is played back, and the playback apparatus 200 is controlled using the HFP / HSP.

  The CPU 1 receives information from the playback device 200 as to whether or not the playback device 200 can execute processing in response to an AVRCP control command. When the CPU 1 determines that the playback apparatus 200 can execute processing in response to the AVRCP control command based on the information received from the playback apparatus 200, the CPU 1 controls the playback apparatus 200 in the first mode. On the other hand, if the CPU 1 determines that the playback device 200 cannot execute processing corresponding to the control command of AVRCP based on the information received from the playback device 200, the CPU 1 plays back using the HFP / HSP in the second mode. The apparatus 200 is controlled.

  The playback device 200 generally includes a CPU 11, a RAM 12, a ROM 13, a content storage unit 14 such as a flash memory, a playback unit 15, a display unit 16, an operation unit 17, and a communication unit 18. The CPU 11 controls each unit of the playback device 200 based on the playback device operation program stored in the ROM 13.

A plurality of music files are recorded in the flash memory 14. The reproduction unit 15 reproduces the music file recorded in the flash memory 14 and transmits the music data to the headset 100 via the communication unit 18. The display unit 16 displays content information (music title, artist name, etc.) of the music file being played. The operation unit 17 receives an instruction based on a user operation, and is an operation button or the like provided on the housing of the playback device 200. The communication unit 18 communicates with the communication unit 4 of the headset 100 and transmits / receives various control commands, control audio data, music data, and the like to / from the headset 100. In this example, the communication unit 18 is a Bluetooth (registered trademark) wireless transceiver.

The operation of this embodiment will be described below. FIG. 3 is a flowchart showing the processing of the CPU 1 of the headset 100. FIG. 4 is a flowchart showing the processing of the CPU 11 of the playback apparatus 200. When the headset 100 and the playback device 200 are connected via Bluetooth (registered trademark) , the CPU 11 of the playback device 200 uses the headset 100 to obtain profile information supported by the playback device 200 using, for example, SPP (Serial Port Profile). (S101). The CPU 1 of the headset 100 receives the profile information supported by the playback device 200 from the playback device 200 and stores it in the RAM 2 (S1). For example, when the headset 200 supports A2DP, AVRCP, and HFP / HSP, information on A2DP, AVRCP, and HFP / HSP is transmitted. When the headset 200 supports A2DP and HFP / HSP, information on A2DP and HFP / HSP is transmitted.

  The CPU 1 of the headset 100 determines whether or not the playback device 200 can execute processing corresponding to AVRCP based on the information received in S1 (S2). When it is determined that the playback device 200 can execute processing corresponding to AVRCP (YES in S2), the CPU 1 sets the control mode to the first mode. As described above, the first mode is a mode in which the playback apparatus 200 is controlled using an AVRCP control command.

  On the other hand, when it is determined that the playback device 200 cannot execute processing corresponding to AVRCP (NO in S2), the CPU 1 sets the control mode to the second mode (S3). As described above, in the second mode, instead of the AVRCP control command, the control audio file stored in the ROM 3 is reproduced, and the reproduced audio data is transmitted to the reproduction apparatus 200 using the HFP / HSP. In this mode, the apparatus 200 is controlled. The CU 1 transmits information (for example, outcalling setup) indicating that communication is performed using HFP / HSP to the playback device 200 (S4).

  The CPU 11 of the playback apparatus 200 determines whether information indicating that communication is performed using HFP / HSP has been received (S102). If received (YES in S102), the CPU 11 executes preparations and settings for communicating with the headset 100 using the HFP / HSP (S103). In addition, when such preparation and setting are unnecessary, the processes of S4, S102, and S103 may be omitted.

  The CPU 1 of the headset 100 determines whether or not an instruction to control the playback device 200 is input by a user operation (S6). That is, it is determined whether or not the operation unit 8 has been operated by the user (the operation button has been pressed). If input (YES in S6), the CPU 1 determines whether or not the control mode is set to the second mode (S7).

  When the control mode is set to the first mode (NO in S7), the CPU 1 transmits an AVRCP control command corresponding to the input instruction to the playback device 200 using AVRCP (S10). For example, when a “play” instruction is input, an AVRCP control command corresponding to “play” is transmitted to the playback device 200. When receiving the AVRCP control command, the playback device 200 executes processing according to the received control command (not shown). For example, upon receiving a “play” control command, the playback device 200 starts playing a music file.

  On the other hand, when the second mode is set (YES in S7), the CPU 1 reads a control audio file corresponding to the input instruction from the ROM 3 (S8), and reads the read audio file to the playback unit 5. The reproduced audio data is transmitted to the reproducing apparatus 200 using HFP / HSP (S9). For example, when a “playback” instruction is input, a control audio file corresponding to “playback” (for example, a sound such as seisei or play) is played back and transmitted to the playback apparatus 200 using HFP / HSP.

  The CPU 11 of the playback device 200 determines whether or not audio data for HFP / HSP control has been received (S104). If received (YES in S104), the CPU 11 executes a process corresponding to the received control audio data (S105). For example, when receiving voice data such as “Saisei or Play”, the CPU 11 starts playing a music file.

  If the playback apparatus 200 cannot execute processing corresponding to AVRCP by the above processing, the headset 100 plays back the audio file stored in the ROM 3 instead of AVRCP, and performs HFP / HSP. And transmitted to the playback apparatus 200. Therefore, it is not necessary for the user to speak into the microphone, and it is possible to solve the problem that the reproduction apparatus 200 cannot be normally controlled due to noise picked up by the microphone.

  Next, processing according to another preferred embodiment of the present invention will be described. In this example, the CPU 1 of the headset 100 sets either the first mode or the second mode in accordance with a user operation, and controls the playback device 200 in the set mode.

  FIG. 5 is a flowchart showing the processing of the CPU 1 of the headset 100. The same processing as in FIG. FIG. 6 is a flowchart showing the processing of the CPU 11 of the playback apparatus 200. The same processing as in FIG. The CPU 1 of the headset 100 determines whether or not an instruction to shift to the second mode is input by a user operation (S11). If not input (NO in S11), the process proceeds to S12.

  On the other hand, if it is input (YES in S11), the CPU 1 sets the control mode to the second mode (S3). The CU 1 transmits information indicating that communication is performed using HFP / HSP to the playback device 200 (S4). The CPU 11 of the playback apparatus 200 determines whether information indicating that communication is performed using HFP / HSP has been received (S102). If received (YES in S102), the CPU 11 executes preparations and settings for communicating with the headset 100 using the HFP / HSP (S103).

  The CPU 1 of the headset 100 determines whether or not an instruction to shift to the first mode is input by a user operation (S12). If not input (NO in S12), the process proceeds to S6. On the other hand, when input (YES in S12), the CPU 1 sets the control mode to the first mode. The other processes are the same as the processes in FIGS. 3 and 4 and will not be described. In this example, the first control mode may be set as the default control mode, or the second mode may be set.

  As described above, the control mode is set by the user operation even when the information indicating whether or not the playback apparatus 200 can execute processing in response to the control command of AVRCP cannot be acquired from the playback apparatus 200. be able to.

  Next, processing according to still another preferred embodiment of the present invention will be described. In this example, the CPU 1 of the headset 100 receives from the playback device 200 information related to an instruction that allows the playback device 200 to execute processing in response to an AVRCP control command. When an instruction based on a user operation is input, the CPU 1 receives from the playback apparatus 200 whether or not the playback apparatus 200 can execute processing in response to the AVRCP control command of the input instruction. Judgment based on information. When it is determined that the playback apparatus 200 can execute the process in response to the input APCCP control command, the CPU 1 controls the playback apparatus 200 using AVRCP in the first mode. On the other hand, when it is determined that the playback apparatus 200 cannot execute the processing in response to the input instruction AVPCP control command, the CPU 1 controls the playback apparatus 200 using the HFP / HSP in the second mode. .

  FIG. 7 is a flowchart showing the processing of the CPU 1 of the headset 100, and FIG. 8 is a flowchart showing the processing of the CPU 11 of the playback device 200. When the headset 100 and the playback apparatus 200 are connected, the control unit 11 of the playback apparatus 200 uses the AVRCP control command information supported by the playback apparatus 200 in the headset 200 using, for example, SPP (Serial Port Profile). (S111). For example, the headset 100 and the playback device 200 manage information on AVRCP control commands that the headset 100 and the playback device 200 support by the player feature bitmask. For example, as shown in FIG. 9, when the playback apparatus 200 supports only “playback” and “stop” commands of AVRCP, information indicating that the playback apparatus 200 supports “playback” and “stop” of AVRCP. The data is transmitted from the playback device 200 to the headset 100.

  The CPU 1 of the headset 100 receives AVRCP control command information supported by the playback device 200 from the playback device 200 and stores it in the RAM 2 (S21). The CPU 1 determines whether or not an instruction to control the playback device 200 is input by a user operation (S22). If input (YES in S22), the CPU 1 determines whether or not the playback apparatus 200 corresponds to the AVRCP control command corresponding to the input instruction based on the information stored in the RAM 2 in S21 (S23). .

  When it is determined that the playback apparatus 200 corresponds to the AVRCP control command corresponding to the input instruction (YES in S23), the CPU 1 sets the control mode to the first mode and controls the AVRCP for the input instruction. The command is transmitted to the playback device 200 using AVRCP (S26). For example, when a “playback” instruction is input, the playback device 200 corresponds to the “playback” AVRCP control command, as shown in FIG. Accordingly, the “playback” AVRCP control command is transmitted to the playback apparatus 200.

  The CPU 11 of the playback device 200 determines whether an AVRCP control command has been received (S112). If received (YES in S112), the CPU 11 executes processing in accordance with the received AVRCP control command (S113). For example, when an AVRCP control command of “playback” is received, the CPU 11 executes playback of a music file.

  On the other hand, when it is determined in S23 that the playback apparatus 200 does not correspond to the AVRCP control command corresponding to the input instruction (NO in S23), the CPU 1 sets the control mode to the second mode and is input. A control audio file corresponding to the instruction is read from the ROM 3 (S24), the read audio file is reproduced by the reproduction unit 5, and the reproduced audio data is transmitted to the reproduction apparatus 200 using HFP / HSP (S25). ). For example, when a “fast forward” instruction is input, as shown in FIG. 9, the playback apparatus 200 does not correspond to the “fast forward” AVRCP control command. Accordingly, a control sound file (for example, a sound such as Hayakuri) corresponding to the “fast forward” instruction is reproduced and transmitted to the reproduction apparatus 200 using HFP / HSP.

  The CPU 11 of the playback apparatus 200 determines whether or not HFP / HSP audio data has been received (S114). If received (YES in S114), the CPU 11 executes processing according to the received audio data (S115). For example, when audio data such as “Hayaokuri” is received, the CPU 11 executes a fast-forward process for music files.

  As described above, in this example, when an instruction that allows the playback apparatus 200 to execute processing in response to an AVRCP control command is input by a user operation, the AVRCP control command is transmitted to the playback apparatus 200. When an instruction that the playback apparatus 200 cannot execute processing corresponding to the AVRCP control command is input by a user operation, the audio file is played instead of the AVRCP control command, and the played back audio data is It can be transmitted to the playback apparatus 200 using HFP / HSP.

  As mentioned above, although preferable embodiment of this invention was described, this invention is not limited to these embodiment. The content playback apparatus may play back content other than music files (for example, video files and still image files). The communication standard is not limited to Bluetooth, and LAN, HDMI, IEEE 1394, USB, and other arbitrary communication standards can be appropriately selected and adopted. The present invention may be provided in the form of a computer program for operating the headset 100 (controller) of the present invention or a recording medium on which the computer program is recorded.
