Show.

  FIG. 21 is a flowchart showing a processing procedure when the content type notification information output unit 3 according to the third embodiment of the present invention receives the content selection notification 1601. Moreover, FIG. 22 is a figure explaining the presentation content of the presentation means 4 in Embodiment 3 of this invention. Hereinafter, the operation of the mobile phone terminal 1 according to the third embodiment of the present invention will be described with reference to FIGS.

  The processing for displaying the title character string and the focus of the content on the LCD 406 after the content type notification information output unit 3 receives the content type information 2001b is the same as that of the second embodiment of the present invention, and thus detailed description is omitted. Only the results are shown in FIG. In FIG. 22A, the LCD 406 displays the character strings “Song No. 1” (G301), “Song No. 2” (G302), and “Song No. 3” (G303) which are the titles of the first to third contents. , And the focus G310.

  Here, when the user operates the cross key 502 upward, the cross key 502 detects the operation and outputs a signal “up” as the operation signal 5001. When the music playback application 501 receives the operation signal 5001 and recognizes that the third content has been selected, the item number “3” (F413) corresponding to the third content (file name “content3.dat”) of the content type information 2001b. ) As a content selection notification 1601.

  When the content type notification information output unit 3 detects the content selection notification 1601, the content type notification information output unit 3 executes processing according to the flowchart shown in FIG. In step S101, the content type notification information output unit 3 obtains the item number “3” included in the content selection notification 1601. In step S102, the content type notification information output unit 3 refers to the content type information 2001b and obtains the content type ID “MIDI / 3D” (F433) corresponding to the item number “3”.

  In step S103, the content type notification information output unit 3 refers to the content type information 2001b, and obtains a playback parameter “NumberOfTracks: 3, NumberOfVirtualSpeakers: 2” corresponding to the item number “3”.

  In step S <b> 104, the content type notification information output unit 3 acquires the playback capability information 6901 related to the playback parameter from the playback capability information output unit 699. Here, the playback capability information output means 699 uses the capability name and capability value of the capability name “DspMaxNumberOfVirtualSpeakers” (F511, F611) as the playback capability information 6901 related to the playback parameter “NumberOfVirtualSpeakers” (F453). Output to 3. When the mobile phone terminal 1 includes the first sound source module, the content type notification information output unit 3 acquires “DspMaxNumberOfVirtualSpeakers: 1”, and when the mobile phone terminal 1 includes the second sound source module, the content type notification information output unit 3 acquires “DspMaxNumberOfVirtualSpeakers: 2”. Become.

  If it is determined in step S105 that the mobile phone terminal 1 includes the first sound source module, the number of virtual speakers (NumberOfVirtualSpeakers) “2” required for playing back the third content is a virtual speaker that can be processed in parallel by the DSP. Since the number (DspMaxNumberOfVirtualSpeakers) of “1” exceeds “1”, the process branches to “YES” and proceeds to step S106, and the value of the reproduction capability becomes “N / A”. On the other hand, when the mobile phone terminal 1 includes the second sound source module, the process branches to “NO” and proceeds to step S107, and the value of the reproduction capability becomes “OK”.

  In step S108, the content type notification information output unit 3 refers to the content type notification information table T303, and determines the content type ID “MIDI / 3D” and the value of the reproduction capability obtained in step S106 or S107 (“OK” or “ N / A ") to obtain the content type notification content. As a result, the content type notification information output means 3 outputs “sound = stereo.wav LED = on vibration = off” (F734) to the second sound source module when the form telephone terminal 1 includes the first sound source module. If “Sound = sfx3d.wav LED = alternate1 vibration = pattern1” (F733) is obtained as the content type notification content. In step S109, the content type notification information output unit 3 outputs the obtained content type notification content (F733 or F734) as content type notification information 3001.

  FIG. 22B shows the presentation contents of the presentation means 4 when the mobile phone terminal 1 includes the first sound source module, and FIG. 22C shows the presentation contents of the presentation means 4 when the mobile phone terminal 1 includes the second sound source module. Show. In FIG. 22B, the speaker 407 outputs a stereo localized sound (a sound stored as waveform data corresponding to approximately one second in the file “stereo.wav”), whereas FIG. In c), the speaker 407 outputs a sound having a three-dimensional sound effect (a sound stored as waveform data corresponding to approximately one second in the file “sfx3d.wav”). Further, in FIG. 22B, the vibrator 410 does not vibrate, whereas in FIG. 22C, the vibrator 410 vibrates. Furthermore, in FIG. 22B, the first LED 404 and the second LED 405 are lit, whereas in FIG. 22C, the first LED 404 and the second LED 405 blink alternately.

  That is, when the user performs a content selection operation, the presenting unit 4 presents sound, vibration, and LED blinking having a three-dimensional sound effect in the case of a mobile phone terminal having sufficient capability for content reproduction. Therefore, the user can intuitively know that the content is reproduced and output with a special effect of three-dimensional sound. On the other hand, when a similar selection operation is performed on a mobile phone terminal that does not have sufficient capability for content playback, a presentation different from the case of a mobile phone terminal that has sufficient capability is performed. Prior to the reproduction of the content, it can be known that a special effect cannot be sufficiently obtained during the reproduction of the content.

  As is clear from the above description, when the user selects content, the mobile phone terminal according to Embodiment 3 of the present invention determines the type of special effect based on the playback capability information indicating the capability of the content playback means. Since the presentation content is determined, it is possible for the user to know more precisely what special effect the content is reproduced with prior to the reproduction of the content.

(F921 to F924) is held. The value of the “presentation capability” field (F921 to F924) indicates that the output device (any of the built-in speaker 407, stereo headphones 408, and monaural headphones 409) that is the output destination of the content playback output signal 6001 indicates the presentation of the content playback output signal. Therefore, it is indicated that the presentation ability is sufficient (“OK”) or not (“N / A”).

  FIG. 28 is a flowchart showing a processing procedure when the content type notification information output unit 3 receives the content type information 2001 according to Embodiment 4 of the present invention. FIG. 29 is a diagram showing the contents of the content type notification information 3001 according to Embodiment 4 of the present invention.

  Hereinafter, the operation of the cellular phone terminal 1 according to the fourth embodiment of the present invention will be described with reference to FIGS. 17 and 25 to 29. Note that description will be made assuming that the metadata 1321a, 1321b, and 1321c (FIG. 17) according to the third embodiment of the present invention are input to the content type determination unit.

  When the content type determination unit 2 generates the content type information 2001c of FIG. 25 from the metadata 1321a, 1321b, and 1321c shown in FIG. 17, “item number” (F1011 to F1013), “content file name” (F1021 to F1023) , “Content type ID” (F1031 to 1033) and “title” (F1041 to F1043) are generated in the same manner as in the third embodiment of the present invention, and the description thereof is omitted.

  Subsequently, the content type determination unit 2 performs a process of generating a field “presentation parameter” (F1051 to F1053) from the metadata 1321a, 1321b, and 1321c. For the second metadata 1321b and the third metadata 1321c, the content type discriminating means 2 includes the description of the number of virtual speakers (NumberOfVirtualSpeakers) as special effect processing information in the metadata. If the number of speakers that output 6001 is not two, it is determined that a special effect cannot be obtained, and the value (right side) of the presentation parameter “NumberOfSpeakers” indicating the number of speakers necessary for reproduction is set to “2” (F1052, F1053). On the other hand, since there is no special effect processing information indicating the number of virtual speakers in the first metadata 1321a, it is determined that monaural playback may be performed, and the value of the presentation parameter “NumberOfSpeakers” is set to “1”. (F1051).

  The content type determination unit 2 outputs the content type information 2001c generated by the operation described above to the content type notification information output unit 3.

  Here, the processing in the content type notification information output unit 3 will be described assuming that the stereo headphones 408 are connected to the headphone jack 403.

  When the content type notification information output unit 3 receives the content type information 2001c, it starts the processing of the flowchart shown in FIG. First, the content type notification information output unit 3 executes the process of the item number “1” (F1011) of the content type information 2001c. In the determination in step S201, the process proceeds to “NO”, and in step S202, the content type ID “MIDI” (F1031) and the presentation parameter “NumberOfSpeakers: 1” (F1051) are obtained.

  In step S203, the presentation unit type information output unit 499 outputs “stereo headphones” as the presentation unit type information 4901 because the active presentation unit, that is, the output device that outputs the content reproduction output signal 6001 is the stereo headphones 408.

  In step S <b> 204, the content type notification information output unit 3 refers to the presentation unit capability information table T <b> 401 and obtains a pair “NumberOfSpeakers: 2, ActiveWhiteVibrationMode: YES” of two presentation capability names and presentation capability values of “stereo headphones”. .

  In the determination in step S205, the value “1” of the presentation parameter “NumberOfSpeakers” does not exceed the presentation ability value “2” corresponding to the presentation ability name “NumberOfSpeakers”, and thus the process proceeds to “NO”. In S207, it is held that the presentation capability is “OK”.

  In step S208, the content type notification information output unit 3 refers to the content type notification information table T304, and since the content type ID is “MIDI” and the presentation capability is “OK”, the content type notification information template “<img src = “Midi. gif ”> $ Title $” (F931) is obtained.

  In step S209, the content type notification information output unit 3 sets the value “title number 1” (F1041) of the title field described in the content type information 2001c to the variable “$ Title $” of the content type notification information template F931. Embedded in the first line “<img src =“ midi. ”Of the content type notification information 3001b shown in FIG. gif ”> music No. 1 <br>” is obtained.

  The content type notification information output means 3 performs the same processing for the item number “2” (F1012) and the item number “3” (F1013) of the content type information 2001c, and the content type notification information shown in FIG. 3001b is obtained. Finally, the process proceeds to “YES” in the determination in step S201, and the content type notification information 3001b is output in step S299.

  The same process is executed when the monaural headphones 409 are connected to the headphone jack 403, but in the process of the item number “2” (F1012) and the item number “3” (F1013) of the content type information 2001c, step S205 is performed. Therefore, unlike the case of the stereo headphones 408, the content type notification information 3001c shown in FIG. 29B is output as the content type notification information 3001.

  FIG. 30 is a diagram illustrating the contents presented by the presentation unit 4 according to the fourth embodiment of the present invention. 30A shows the presentation contents of the presentation unit 4 when the stereo headphones 408 are connected to the headphone jack 403, and FIG. 30B shows the presentation contents when the monaural headphones 409 are connected. .

  When the stereo headphones 408 are connected to the headphone jack 403, the icons G402 and G403 corresponding to the second metadata 1321b and the third metadata 1321c, respectively, are visualized animation images “midi-3d.gif”. On the other hand, when the monaural headphones 409 are connected, the icon G407 is a visualization of a still image “midi-3d_noanimation.gif” having a different color, shape, and size from “midi-3d.gif”. , G408. In addition, regarding the character string display, the font, size, color, presence / absence of blinking, and display position are different when the stereo headphones 408 are connected (G405, G406) and when the monaural headphones 409 are connected (G409, G410). Is different.

  That is, when the monaural headphone 409 that is an output device that does not have sufficient capability for presentation of content including three-dimensional sound effects is connected to the headphone jack 403, the stereo headphone 408 that is an output device that has sufficient capability is connected. Since the content information is presented differently from the content information, the user can know prior to the reproduction of the content that the special effect cannot be sufficiently obtained during the reproduction of the content.
