It is determined whether or not the PV data of the music having the ID. In addition, the wording used to determine whether the data is PV data is not limited to the wording described above. Moreover, the determination method of whether moving image data is the PV data of the music selected by the user is not restricted to the method mentioned above.

  When it is determined that the moving image data that has started to be received is PV data of a song with a song ID read from the reserved song table 22a (S27: YES), the control unit 20 of the karaoke apparatus 2 uses the PV data (received movie data). The singing start position in the PV data is specified based on the audio data (audio data associated with the moving image data) included in the video data (S28). For example, the control unit 20 performs frequency conversion on voice data, determines a position where a frequency component (frequency waveform) of a human voice first appears, and specifies this position as a singing start position. In addition, the information which shows a singing start position may be previously added to PV data (video data), and in the case of such PV data, the control part 20 starts singing based on the information added to PV data. The position can be specified.

  In addition, the control part 20 of the karaoke apparatus 2 receives PV data sequentially from the head, and specifies a song start position based on the audio | voice data contained in the received PV data. For example, some PV data published via the network N has advertisement data added to the head. In the case of such PV data, the control unit 20 can specify the start position (song start position) of the PV data based on the difference in the characteristics of the audio data between the advertisement data and the PV data. Moreover, you may identify a song start position based on moving image data other than the structure which identifies a song start position based on the audio | voice data matched with moving image data. For example, in the case of PV data with advertisement data added to the head, the control unit 20 determines the start position (singing start position) of the PV data based on the difference in the characteristics of the moving image data between the advertisement data and the PV data. Can be identified.

  When the singing start position in the moving image data (PV data) that has started reception is specified, the control unit 20 of the karaoke apparatus 2 specifies the vocal sound start position in the song data of the song ID read from the reserved song table 22a (S29). ). In addition, the control part 20 can specify a vocal sound start position based on the various information contained in music data.

  The control unit 20 of the karaoke apparatus 2 uses the moving image data (PV data) that has been received based on the vocal sound starting position in the music data specified in step S29 and the singing start position in the moving image data specified in step S28. The reproduction start position is specified (S30). For example, the control unit 20 calculates the time from the performance start position of the music data to the vocal sound start position. And the control part 20 specifies the position before the calculated time to the reproduction | regeneration start position from the song start position specified by step S28 in the moving image data (PV data) which started reception. In addition, the control part (audio | voice specific part, moving image specific part) 20 specifies the part (partial moving image data and partial audio | voice data) corresponding to music data among moving image data by specifying the reproduction start position in moving image data. Can be identified.

  When the reproduction start position of the moving image data is specified, the control unit (display control unit) 20 of the karaoke apparatus 2 uses the moving image monitor device 6 based on the moving image data (PV data) sequentially received from the specified reproduction start position. Display is started (S31). Specifically, the control unit 20 sequentially transmits moving image data sequentially received by the first communication unit 23 from the second communication unit 24 to the monitor device 6 via the relay device 5, and the moving image data based on the moving image data is transmitted. It is displayed on the monitor device 6. In addition, the control part 20 displays the moving image based on moving image data on the monitor apparatus 6 as a background image of the lyrics contained in music data.

  On the other hand, the control unit (sound volume control unit) 20 of the karaoke apparatus 2 performs a process (for example, a mute process) for reducing the sound volume based on the audio data received via the network N together with the moving image data (S32). Moreover, the control part 20 of the karaoke apparatus 2 reads the music data of the music ID read from the reserved music table 22a in step S21 from the storage part 22, and starts the audio output based on the read music data on the speaker 7 (S33). . At this time, the control unit (audio output unit) 20 outputs not only audio output based on music data but also audio based on audio data received together with moving image data. Note that the volume of the voice based on the voice data is reduced in step S32, so that it does not interfere with the audio output.

If it is determined in step S27 that the moving image data that has started reception is not PV data (S27: NO), the control unit 20 of the karaoke apparatus 2 skips the processing in steps S28 to S30 and is based on the sequentially received moving image data. Display of the moving image on the monitor device 6 is started (S31). Moreover, the control part 20 of the karaoke apparatus 2 performs the process which reduces the sound volume based on the audio | voice data received with the moving image data (S32), and outputs the audio output based on the music data of the music ID read from the reserved music table 22a. The process starts with the speaker 7 (S33).
Even when the moving image data that has started to be received is not PV data, for example, the reproduction start position is determined based on the moving image data or the audio data associated with the moving image data, and the determined reproduction start position is used. Video display based on video data and audio output based on audio data may be started. For example, in the case of moving image data with advertisement data added to the head, the control unit 20 of the karaoke apparatus 2 may specify the end position of the advertisement data and determine this position as the reproduction start position.

  The control unit 20 of the karaoke apparatus 2 determines whether or not the audio output started in step S33 has ended (S34). Specifically, when the audio output based on the music data is executed to the end, or when the user operates the input device 3 (karaoke device 2) and instructs the output stop during the audio output, the control unit 20 Determines that the audio output has ended. When it is determined that the audio output has ended (S34: YES), the control unit 20 of the karaoke apparatus 2 ends the moving image display started in step S31 (S35). That is, the control unit 20 ends the moving image display started with the start of the audio output (music performance) based on the music data when the audio output ends. In addition, when ending a moving image display, the control part 20 also complete | finishes the audio | voice output based on the audio | voice data received with the moving image data.

  If it is determined that the audio output has not ended (S34: NO), the control unit 20 of the karaoke apparatus 2 determines whether or not the moving image display started in step S31 has ended (S36). When it is determined that the moving image display has not ended (S36: NO), that is, when both the audio output based on the music data and the moving image display based on the moving image data have not ended, the control unit 20 performs the process in step S34. return.

  When it is determined that the moving image display is finished (S36: YES), that is, when the moving image display is finished before the audio output is finished, the control unit 20 of the karaoke apparatus 2 uses the first communication unit 23 to connect the network N. The display of the moving image based on the moving image data received via the network is started again (S37), and the process returns to step S34. At this time, the control unit 20 of the karaoke apparatus 2 may be configured to display again a moving image based on the same moving image data as the previously displayed moving image data, or may be configured to display a moving image based on different moving image data. For example, when specifying moving image data to be used for a background image via a reservation reception screen, the user can specify whether the same moving image data is used (reproduced) only once or repeatedly (reproduced). It is good. In addition, when the moving image data to be used for the background image is specified via the reservation reception screen, the user may specify a plurality of moving image data and the use order (reproduction order) of each moving image data. Thereby, the control part 20 of the karaoke apparatus 2 switches whether the moving image display should be ended or the same or different moving image display should be started according to the user's designation when the moving image display is ended before the audio output is ended. be able to.

Further, if the data information stored in the reserved song table 22a is search information, the control unit 20 of the karaoke apparatus 2 will end up displaying the moving image before the audio output is finished, if the video display is finished. The search process based on the corresponding data information may be performed again to start displaying a moving image based on the searched moving image data. In this case, while the audio output is being performed, a plurality of moving images related to the music being output are sequentially displayed.
In addition, when displaying the same moving image, the control unit 20 may be configured to start the display from the reproduction start position determined in step S30, or start the display after newly performing the reproduction start position specifying process. It may be configured. In addition, when displaying different moving images, the control unit 20 may be configured to start the display after performing the reproduction start position specifying process for different moving image data, or start the display without performing the specifying process. It may be configured.

  When the audio output is finished and the moving image display is finished, the control unit 20 of the karaoke apparatus 2 determines whether or not the operation end is instructed (S38). When it is determined that the operation end is not instructed (S38: NO), the control unit 20 of the karaoke apparatus 2 returns the process to step S21, and performs step information about the music information stored at the head of the reserved music table 22a. The processes after S21 are repeated. When it is determined that the operation end has been instructed (S38: YES), the control unit 20 of the karaoke apparatus 2 ends the karaoke process.

  7 and FIG. 8, the karaoke apparatus 2 can acquire (receive) moving image data based on the data information acquired from the mobile terminal 1, and can use the received moving image data as a background image of karaoke. In the process shown in FIGS. 7 and 8, the karaoke apparatus 2 also ends the moving image display based on the moving image data when the audio output is ended. In addition to this, even after the audio output is completed, the moving image display based on the moving image data may be continued until the karaoke apparatus 2 starts the audio output based on the next reserved music data. Also, in this case, between the end of audio output and the start of the next audio output, the sound volume based on the sound data received together with the moving image data is returned to the original sound volume and the sound is output. Good. That is, only a moving image based on moving image data may be displayed during audio output, and a moving image display based on moving image data and an audio output based on audio data may be performed in an audio output waiting state. As a result, it is possible to view arbitrary content data when waiting for audio output.

  In the processing shown in FIGS. 7 and 8, when the moving image data designated as the background video is PV data, the karaoke apparatus 2 specifies the singing start position in the PV data, and the specified singing start position and music data can be stored. The playback start position in the PV data is specified based on the vocal sound start position. In addition, a configuration in which the user manually designates the reproduction start position in the moving image data designated as the background video may be used. For example, on the reservation reception screen, the user can reproduce (moving image display and audio output) the moving image data designated as the background image on the portable terminal 1 and can execute the fast forward function and the rewind function. And it is good also as a structure which can designate the reproduction | regeneration start position which a user wants to use for the background image | video of karaoke based on the displayed moving image and the output audio | voice via a reservation reception screen. In this case, the reservation information transmitted from the portable terminal 1 to the karaoke apparatus 2 includes not only data information but also information indicating the reproduction start position. Thereby, the moving image display based on the moving image data can be performed from an arbitrary reproduction start position. In this case, the data information of the moving image data designated as the background video and the information indicating the reproduction start position designated by the user may be stored in the storage unit 12 in association with each other. Thereby, when the same moving image data is used for the background image of karaoke next time, it is not necessary to designate the reproduction start position again. Further, the information on the reproduction start position stored in the storage unit 12 of the mobile terminal 1 as described above may be shared among a plurality of mobile terminals 1. For example, the mobile terminal 1 requests a plurality of other mobile terminals for information on the reproduction start position of certain moving image data, and the mobile terminal having the requested information is requested from among other mobile terminals. It is good also as a structure which transmits the information of a reproduction | regeneration start position to the portable terminal 1.

  In the processes shown in FIGS. 7 and 8, it is desirable that the processes in steps S26 to S30 be performed before the audio output based on the music data is started. Therefore, for example, the processing of steps S21 and S22 and the processing of steps S26 to S30 may be performed when the background video is specified during the audio output of the music piece with the previous reservation order. Further, the process of step S31 and the processes of steps S32 and S33 can be executed in parallel.

In the present embodiment, designation of arbitrary video data used for the background image of the lyrics displayed on the monitor device 6 is not only performed when making a karaoke reservation, but also when a karaoke reservation has already been made or audio output has already started. It can also be performed on existing music.
Below, the process which the portable terminal 1 performs when a user designates the moving image data used for a background image | video using the portable terminal 1 except when performing a karaoke reservation is demonstrated.

  FIG. 9 is a flowchart showing a procedure of processing performed by the mobile terminal 1. The control unit 10 of the mobile terminal 1 executes a predetermined application program stored in the storage unit 12, so that a background image of a song that is already being played or a song that is already reserved (a song waiting for audio output) is displayed. A reception screen (hereinafter referred to as a background reception screen) for receiving arbitrary video data to be used is displayed on the touch panel 13. Note that the background reception screen displays not only the music data used for the background video when the music is specified and the specified music is played (audio output), but no music is specified and any music is played. It is also possible to accept (specify) moving image data used for the background video at the time. The user operates the touch panel 13 to specify moving image data to be used for the background video on the background reception screen. In this case as well, the moving image data used for the background image may be moving image data published via the network N, moving image data stored in an external device accessible by the karaoke device 2, and the like. Audio data may be associated with the moving image data.

  The control unit 10 of the mobile terminal 1 determines whether or not designation of moving image data has been received via the touch panel 13 (S41). If it is determined that it has not been received (S41: NO), the control unit 10 of the mobile terminal 1 waits until it is received. When it is determined that the designation of the moving image data has been received (S41: YES), the control unit 10 of the mobile terminal 1 determines whether or not the designation of the music that uses the specified moving image data for the background image has been received (S42). . When it is determined that the designation of the music is not accepted (S42: NO), that is, when the music using the designated moving image data for the background video is not designated, the control unit 10 of the portable terminal 1 is designated. The data information of the moving image data is transmitted to the karaoke apparatus 2 (S43), and the process ends. At this time, the control unit 10 may transmit the data information together with information indicating that the music using the moving image data for the background video is not designated.

  When it is determined that a song that uses the designated moving image data for the background video is designated (S42: YES), the control unit 10 of the mobile terminal 1 is the song that is currently outputting audio. It is determined whether or not (S44). For example, the control unit 10 acquires information (music ID, music title, singer name, etc.) of the music currently being output from the karaoke device 2 and the music being reserved (waiting for audio output) (music ID, music title, singer name, etc.) 13 is displayed. And the control part 10 receives selection of the music which uses designated moving image data for a background image from the music in display by operation of the touch panel 13 by a user. Therefore, the control unit 10 can determine whether the music that uses the specified moving image data for the background video is the music that is currently outputting audio or the music that is waiting for audio output according to the selected music.

  When it is determined that the music is not being output (S44: NO), that is, when the music is waiting for audio output (reserved), the control unit 10 of the portable terminal 1 specifies the music ID of the specified music and the specified music. The reservation information including the data information of the moving image data is transmitted from the second communication unit 15 to the karaoke apparatus 2 (S45), and the process is terminated. The control unit 20 of the karaoke apparatus 2 that has received such reservation information stores the data information of the received reservation information in the column of background video information corresponding to the song ID of the received reservation information in the reserved song table 22a. Store.

  If it is determined that the music is being output as audio (S44: YES), the control unit 10 of the mobile terminal 1 uses the data information of the specified video data as the background video of the music currently being output as audio. It transmits to the karaoke apparatus 2 with the information which shows using (S46), and complete | finishes a process.

Next, the process performed by the karaoke apparatus 2 when moving image data is designated via the background reception screen and the mobile terminal 1 transmits data information as described above will be described. FIG.10 and FIG.11 is a flowchart which shows the procedure of the process which the karaoke apparatus 2 performs.
The control unit 20 of the karaoke device 2 determines whether or not the data information transmitted by the mobile terminal 1 in step S43 or S46 in FIG. 9 is acquired by the second communication unit 24 via the relay device 5 ( S51). When it is determined that the data information has not been acquired (S51: NO), the control unit 20 of the karaoke apparatus 2 stands by while performing other processes.

  When it is determined that the data information has been acquired (S51: YES), the control unit 20 of the karaoke apparatus 2 is currently outputting audio data based on the data information based on the information acquired from the portable terminal 1 together with the data information. It is determined whether the moving image data is used for the background image of the song (S52). When it is determined that the video data is used for the background video of the music being output (S52: YES), the control unit 20 of the karaoke device 2 designates the video as the background video based on the data information acquired from the mobile terminal 1. The received video data is started (S53). Note that the control unit 20 receives the moving image data by the same process as step S26 in FIG. Further, the control unit 20 receives not only moving image data but also audio data associated with the moving image data via the network N.

The control unit 20 of the karaoke apparatus 2 determines whether or not the moving image data that has been received is the PV data of the music that is being output (S54). Note that the control unit 20 determines whether or not the data is PV data by the same processing as step S27 in FIG.
When it is determined that the moving image data that has started to be received is the PV data of the music being output (S54: YES), the control unit 20 of the karaoke apparatus 2 performs the PV data through the same process as step S28 in FIG. The singing start position in (received moving image data) is specified (S55).

  Next, the control unit 20 of the karaoke apparatus 2 specifies information (music data information) indicating the vocal sound start position and the current output position in the music data of the music being output (S56). The control unit 20 of the karaoke apparatus 2 specifies the playback start position in the moving image data (PV data) designated as the background video based on the specified music data information and the singing start position specified in step S55 (S57). ). For example, the control unit 20 calculates the time from the vocal sound start position of the music data to the current output position based on the specified music data information. And the control part 20 specifies the position after the calculated time to the reproduction | regeneration start position from the song start position specified by step S55 in the moving image data (PV data) which started reception.

  The control unit 20 of the karaoke apparatus 2 starts displaying the moving image on the monitor device 6 based on the moving image data (PV data) sequentially received from the reproduction start position of the specified moving image data (S58). Further, the control unit 20 of the karaoke apparatus 2 performs a process (for example, a mute process) for reducing the sound volume based on the sound data sequentially received via the network N together with the moving image data (S59), along with the audio output being executed, Audio output based on the audio data received together with the moving image data is started (S60). Note that the volume of the voice based on the voice data is reduced in step S59, so that it does not interfere with the audio output.

If it is determined in step S54 that the moving image data that has started reception is not PV data (S54: NO), the control unit 20 of the karaoke apparatus 2 skips the processing of steps S55 to S57 and is based on the sequentially received moving image data. Display of the moving image on the monitor device 6 is started (S58). Moreover, the control part 20 of the karaoke apparatus 2 performs the process which reduces the sound volume based on the audio | voice data received with moving image data (S59), and starts the output of the audio | voice which reduced the sound volume with the audio output in process. (S60).
Even when the moving image data that has started to be received is not PV data, for example, the reproduction start position is determined based on the moving image data or the audio data associated with the moving image data, and the determined reproduction start position is used. Video display based on video data and audio output based on audio data may be started. For example, in the case of moving image data with advertisement data added to the head, the control unit 20 of the karaoke apparatus 2 may specify the end position of the advertisement data and determine this position as the reproduction start position.

  When the control unit 20 of the karaoke apparatus 2 starts displaying the moving image based on the moving image data on the monitor device 6 in step S58, the remaining audio output time in the music data being output is a predetermined time (for example, 10 seconds) or more may be determined. Then, the control unit 20 may start displaying a moving image on the monitor device 6 when the remaining audio output time is equal to or longer than a predetermined time. That is, when the remaining audio output time is less than the predetermined time, the control unit 20 may not display the moving image on the monitor device 6. At this time, the control unit 20 also does not perform the process of reducing the volume of the sound based on the audio data corresponding to the moving image data (S59) and the process of outputting the sound with the reduced volume (S60).

  The control unit 20 of the karaoke apparatus 2 determines whether or not the audio output being executed has ended (S61). Specifically, when the audio output based on the music data is executed to the end, or when the user operates the input device 3 (karaoke device 2) and instructs the output stop during the audio output, the control unit 20 Determines that the audio output has ended. When it is determined that the audio output has not ended (S61: NO), the control unit 20 of the karaoke apparatus 2 continues the audio output based on the music data and the moving image display based on the moving image data. If it is determined that the audio output has ended (S61: YES), the control unit 20 of the karaoke apparatus 2 ends the moving image display started in step S58 (S62). That is, the control unit 20 ends the moving image display when the audio output (music performance) based on the music data ends. In addition, when complete | finishing a moving image display, the control part 20 also complete | finishes the audio | voice output based on the audio | voice data started by step S60.

  With the above-described processing, it is possible to display an arbitrary moving image based on moving image data designated by the user via the mobile terminal 1 as a background image even for a piece of music for which audio output has already been started. When the specified moving image data is PV data, the reproduction start position (display start position) in the moving image data is specified based on the current audio output position. Therefore, the display timing of the moving image based on the moving image data by the monitor device 6 and the audio output timing by the karaoke device 2 can be synchronized with respect to the music for which audio output has already started.

  When it is determined in step S52 that the video data is not used for the background video of the music being output (S52: NO), the control unit 20 of the karaoke apparatus 2 is currently performing audio output based on any of the music data. It is determined whether or not (S63). When it is determined that the audio output is not being executed (S63: NO), the control unit 20 of the karaoke device 2 monitors an error message indicating that the moving image data designated via the portable terminal 1 cannot be displayed on the karaoke device 2. The information is displayed on the device 6 (S64), and the process is terminated. In addition, the control part 20 of the karaoke apparatus 2 is good also as a structure which transmits an error message to the portable terminal 1 which has transmitted data information, and displays it on the touch panel 13 of the portable terminal 1. FIG.

  If it is determined that audio output is being executed (S63: YES), the control unit 20 of the karaoke apparatus 2 starts to receive moving image data based on the data information acquired from the mobile terminal 1 (S65). And the control part 20 of the karaoke apparatus 2 starts the display to the monitor apparatus 6 of the moving image based on the moving image data received sequentially (S66). At this time, the control unit 20 also starts audio output based on audio data sequentially received via the network N together with the moving image data. In addition, the control unit 20 of the karaoke device 2 sends the video data to the video monitor device 6 based on the video data that is sequentially received when the remaining audio output time of the music data being output is equal to or longer than a predetermined time (for example, 10 seconds). It is good also as a structure which starts a display. In addition, the control unit 20 of the karaoke device 2 suspends the video display on the monitor device 6 when the audio is not being output or when the remaining audio output time in the music data being output is less than a predetermined time. Then, it may be configured to display the suspended video in synchronization with the timing of starting audio output based on the reserved music data.

  The control unit 20 of the karaoke apparatus 2 determines whether or not the display of the moving image based on the sequentially received moving image data has been completed (S67), and when it is determined that the display has not ended (S67: NO), the moving image display and audio If the output is continued and it is determined that the process has been completed (S67: YES), the process is terminated. Thereby, the karaoke apparatus 2 can display the moving image based on the moving image data acquired from the external device based on the data information on the monitor device 6. Whether or not to display an arbitrary moving image depending on whether or not audio output by the karaoke apparatus 2 is being executed when an instruction to display a moving image based on moving image data is given without specifying a song. Can be switched.

  In the processing shown in FIGS. 10 and 11, after the audio output is completed, the moving image display based on the moving image data is continued until the karaoke apparatus 2 starts the audio output based on the next reserved music data. But you can. Also, in this case, between the end of audio output and the start of the next audio output, the sound volume based on the sound data received together with the moving image data is returned to the original sound volume and the sound is output. Good.

  In the karaoke system of the present embodiment, the karaoke apparatus 2 is configured to continue moving image display based on moving image data received via the network N until the audio output ends. Note that the karaoke apparatus 2 processes the moving image data so that the moving image display time is approximately equal to the audio output time, depending on the output time required for audio output based on the music data and the moving image display time based on the moving image data. You may have the structure to do. Specifically, the control unit (comparison unit) 20 of the karaoke device 2 specifies the remaining output time of the music being output, and the remaining display time of the moving image based on the moving image data currently displayed on the monitor device 6 Compare with For example, when the moving image display time is longer than the audio output time, the control unit 20 of the karaoke apparatus 2 processes the moving image data so as to shorten the moving image display time (for example, increases the reproduction speed), and after the processing The moving image based on the moving image data is displayed on the monitor device 6. For the music waiting for audio output, the karaoke apparatus 2 specifies the output time required for audio output, and compares it with the display time of the moving image based on the moving image data specified for the background image of this song. When the moving image display time is longer than the audio output time, the control unit 20 of the karaoke apparatus 2 processes the moving image data so that the moving image display time is approximately the audio output time, and the processed moving image data Is displayed on the monitor device 6. Thereby, the end timing of the audio output can be matched with the end timing of the display by the monitor device 6 of the moving image based on the moving image data.

In the karaoke system of the present embodiment, the user searches for moving image data to be used for the background image of karaoke in advance, and designates the searched moving image data via the reservation reception screen or the background reception screen. Met. Furthermore, the mobile terminal 1 may have a configuration in which the moving image data is automatically searched based on the music information that the user has reserved for karaoke or the music information of the music that is going to be reserved for karaoke via the reservation reception screen.
Below, the process which the portable terminal 1 searches automatically the moving image data used for the background image | video of karaoke is demonstrated.

FIG. 12 is a flowchart illustrating the procedure of the moving image data search process performed by the mobile terminal 1, and FIG. 13 is a schematic diagram illustrating a display screen example of the mobile terminal 1.
The control unit 10 of the portable terminal 1 performs the following processing when the user designates arbitrary moving image data as a background image of karaoke. First, the control unit 10 of the mobile terminal 1 acquires music information such as a music ID, a music title, and a singer name of a music that is desired to use arbitrary video data as a background video (S71). Specifically, when the user selects a song for which karaoke reservation is to be made via the reservation reception screen, the control unit 10 acquires song information of the selected song. In addition, when the user specifies the video data that the user wants to use for the background video via the background reception screen, the user is currently outputting the music that the background video is to be changed to any video data before specifying the video data. Select from music and music waiting for audio output. And the control part 10 acquires the music information of the music which the user selected via the background reception screen. For example, the control unit 10 acquires the music information of the music from the karaoke apparatus 2.

  As shown in FIG. 13A, the control unit 10 of the portable terminal 1 displays the acquired music information and also displays a search screen on the touch panel 13 that accepts selection of whether to perform automatic search or manual search (S72). . In the search screen shown in FIG. 13A, search processing based on music information is automatically performed on moving image data stored in a predetermined server device (“automatic search within a predetermined server”) or via the network N. It is possible to select whether to perform automatically on the moving image data released ("automatic search in the network") or manually by the user ("manual search"). Note that “automatic search within a predetermined server” and “automatic search within a network” may be collectively referred to as “automatic search”.

  The control unit 10 of the portable terminal 1 determines whether execution of automatic search is selected via the search screen (S73).
