Description

  The present invention relates to a playback section editing device, a mobile phone device, and a playback section editing method for editing a playback section of content when the playback time of the content stored in a storage medium is limited by the remaining battery level or the like.

  A playback device that plays back content such as music data stored in a storage medium, such as an audio player or a mobile phone, operates by receiving power from a battery such as a dry battery or a rechargeable battery. In these playback apparatuses, if the content playback time is limited due to a decrease in the remaining amount of the battery or the like, it is sometimes impossible to play back all the content. Here, all contents mean either all contents stored in the storage medium or all contents registered in a specific playlist (a list of contents to be continuously played back).

  To solve this problem, when the remaining battery level falls below a predetermined threshold, the user is notified that the remaining battery level is low by slowing the playback speed of the section other than the rust part from the normal time. It is known to promote battery replacement or charging (see, for example, Patent Document 1).

  In addition, it is known to select and reproduce appropriate music data within a limited reproduction time that accompanies a decrease in the remaining battery level (see, for example, Patent Document 2).

  Furthermore, the time that the device can operate is predicted according to the remaining battery level, and the silent part is cut to complete the playback of video and audio data within the predicted time, or the playback speed is faster than the specified speed. By doing so, it is known that all video and audio recorded on a recording medium can be viewed (see, for example, Patent Document 3).

  However, the example described in Patent Document 1 described above notifies the user that the remaining amount of the battery is low by an acoustic effect that slows the reproduction speed when the remaining amount of the battery is low. It was not the case that all contents were played within a limited time according to the remaining battery level.

  Moreover, in the example described in Patent Document 2, a music data file that can be played back within a limited time associated with the remaining battery level is selected, and not all content is played back. In addition, it is not intended to edit and reproduce which part of the content is to be reproduced.

  Furthermore, the example described in Patent Document 3 changes the playback speed of video and audio data in accordance with the remaining battery level, and although all the content can be played back, the naturalness of viewing is lost. was there.

  The present invention has been made in view of the above circumstances, and can reproduce all content without changing the reproduction speed when the reproduction time of the content stored in the storage medium is limited. It is an object of the present invention to provide a playback section editing device, a mobile phone device, and a playback section editing method.

  In order to achieve the above object, a first playback section editing device according to the present invention includes an end time determining unit that determines an end time at which content playback ends, and an end at which the playback ends when the content is played back.

  In the fourth playback section editing device of the present invention, the playback section determination unit is configured to exclude a predetermined section from the playback section based on a section priority for determining the playback section.

  With this configuration, for example, a priority based on a favorite level or a playback frequency for each content is referred to, and a section of a content with a lower priority is skipped without being played back. Can be performed.

  In the fifth playback section editing device of the present invention, the end time determination unit determines the end time based on the remaining battery level.

  With this configuration, when the playback time of the content stored in the storage medium is limited as the remaining battery level decreases, the playback section is determined for each content according to the limited time, and the determined playback section is Since playback is performed, all contents can be played back without changing the playback speed.

  The sixth playback section editing device of the present invention includes a processing information recording unit that records a processing start time for starting a predetermined process in the playback section editing device, and the end time determination unit is The processing start time is set as the end time.

  With this configuration, when the playable time of content stored in the storage medium is limited due to factors other than the remaining battery level, for example, a viewing reservation is set in a DTV (digital television) terminal or the like, and viewing starts When playback of content must be completed by the time, etc., the playback section is determined for each content according to the limited time, and the determined playback section is played back, so all without changing the playback speed Content can be played.

  Further, the seventh playback section editing device of the present invention has a trigger detection section for detecting a trigger for starting the determination process by the end time determination section, and the end time determination section is configured as the playback section determination section. When the trigger detection unit detects the trigger after determining the playback section, the end time is determined again. When the playback section determination unit changes the end time, the playback section of the content is determined again. The configuration is determined.

  With this configuration, even after the playback section has been determined once, it is possible to edit the playback section again based on, for example, the state of the device and user operation, and the playback section that reflects the latest status of the device is determined. be able to.

  Hereinafter, a playback section editing apparatus according to an embodiment of the present invention will be described with reference to the drawings. In the embodiment of the present invention, a playback section editing device in a mobile phone is exemplified.

  FIG. 1 is a diagram showing an example of the configuration of a playback section editing device according to an embodiment of the present invention. In FIG. 1, the mobile phone 1 includes a playback section editing device 10, a battery 20, a storage medium 30, and a playback unit 40. The playback section editing apparatus 10 includes a condition detection unit 101, a comparison unit 102, a data reading unit 103, and a playback control unit 104. Note that the playback section editing device 10 may include a battery 20, a storage medium 30, and a playback unit 40. The mobile phone 1 is an example of a “mobile phone device”. The storage medium 30 has a function as a “content holding unit”.

  In response to a request from the comparison unit 102, the condition detection unit 101 detects the remaining amount of the battery 20, confirms a DTV viewing reservation, which will be described later, and the like, and corresponds to the detected remaining battery amount and the confirmed viewing reservation. Is calculated and the comparison unit 102 is notified. The status of the DTV viewing reservation is confirmed by referring to a viewing reservation table stored in the storage medium 30, for example. When the viewing reservation of DTV is made, the time from the present to the viewing start time can be set as the content reproducible time. The condition detection unit 101 has a function as an “end time determination unit”. It should be noted that the present technology is effective when it is known that the video output unit or the audio output unit of the apparatus is occupied in a certain time zone, not limited to the DTV viewing reservation.

  The data reading unit 103 reads content data such as music and video stored in the storage medium 30 such as a semiconductor memory and notifies the comparison unit 102 of the content data.

  Based on the occurrence of a trigger, which will be described later, the comparison unit 102 requests the condition detection unit 101 to detect the remaining amount of the battery 20 and the like and calculate the content reproducible time, and the reproducible time notified from the condition detection unit 101 The total reproduction time obtained from each content data, that is, the time required for reproduction of all contents is compared. When the reproducible time is shorter than the time required for reproduction of all the contents, the reproduction section is determined for each content and the reproduction section information is notified to the reproduction control unit 104. The comparison unit 102 functions as a “playback section determination unit” and a “trigger detection unit”.

  The playback control unit 104 controls the playback of content in the playback unit 40 based on the playback section information sent from the comparison unit 102.

  Next, the operation of the playback section editing device 10 configured as described above will be described. FIG. 2 is a flowchart for explaining an example of the operation procedure of the playback section editing device 10.

  First, in step S101, when the comparison unit 102 detects the occurrence of a trigger to be described later, the comparison unit 102 requests the condition detection unit 101 to detect the remaining amount of the battery 20, confirm the DTV viewing reservation, and calculate the content playable time. To do.

  The above triggers are the activation of the playback unit 40, trick playback (fast forward, rewind), playlist change, reordering of songs, addition of viewing reservations, change of playback mode (shuffle playback, repeat playback), playback volume When there is a user action such as change or effect change, when a replayable time is shortened by executing another program after sending / receiving mail or at the end of the call, when the battery charging cable is inserted / removed, This occurs when the playable time is changed due to insertion / extraction or when switching to BlueTooth (registered trademark). The time of switching to Bluetooth is, for example, a time of switching the playback output destination between the mobile phone 1 and a Bluetooth (registered trademark) compatible device (not shown).

  Based on the request from the comparison unit 102, the condition detection unit 101 measures the remaining amount of the battery 30 and confirms the viewing reservation of the DTV (step S102), and the remaining reproduction is performed from the measured remaining amount of the battery and the confirmed viewing start time. The possible time is calculated and notified to the comparison unit 102 (step S103).

  The data reading unit 103 is stored in the storage medium 30 based on the request of the comparison unit 102, the playback time of all the contents included in the current playlist, the playback section information set by the content creator or user, Content information such as rust information, favorite degree, and reproduction frequency is read and notified to the comparison unit 102 (step S104). Here, the current playlist indicates a playlist that is currently being reproduced or a playlist that is currently selected. The favorite degree and the incoming call setting may be acquired from the server or the like together with the content, or may be set by the user using an input unit (not shown).

  The comparison unit 102 compares the content reproduction time included in the content information acquired from the data reading unit 103 with the remaining reproducible time calculated in step S103, and the content included in the current playlist within the remaining reproducible time. It is determined whether or not it is possible to reproduce all (step S105).

  If it is determined that all the contents cannot be reproduced, the comparison unit 102 obtains a reproducible time for each song (step S106). The time allotted to each song may be the same, but if information such as the degree of favorite and the frequency of reproduction differ for each song is acquired from the storage medium 30, a song with a high favorite is played back for a long time. Etc., and can be inclined by the song.

  For example, it is conceivable that weighting is performed so that the priority of a song having a high degree of favorite or a song having a high reproduction frequency is increased. As a result of performing the weighting, the music with low priority may be deleted from the playlist.

  Then, the comparison unit 102 determines a digest playback section from the calculated playable time for each song (step S107).

  For example, when the content information sent from the data reading unit 103 includes playback section information (such as incoming call setting information), the section in which digest playback is performed is determined with priority. At this time, when there are a plurality of pieces of reproduction section information, for example, the time for all the combination patterns is calculated, and the optimum section is selected among them.

  The playback section information included in the content information is information such as a playback section and a chorus section that are included in Chaku-Uta (registered trademark) data in advance, and the playback section is determined using this information.

  This rust information may be obtained each time with the mobile phone 1, but for example, it is necessary to detect rust with music management software or the like that runs on a PC, and record the rust information accompanying the content. Sometimes it may be read. Furthermore, when the rust information is not recorded but the rust section is calculated when necessary, an operation such as adjusting a threshold for obtaining the rust section so that an appropriate section becomes the rust section is performed. May be. This threshold adjustment may be gradual. For example, by making the priority of the chorus section higher than the priority of the sections other than the chorus, it can be easily selected as the reproduction section.

  Also, by extracting the feature amount of the music, it is possible to detect the section where the music is transposed, the section where the tempo, the bass line, the drum pattern change, the section where the number of musical instruments changes, etc., and determine the playback section. . For example, when the comparison unit 102 determines that the section is exciting from the feature amount of the music, the priority of the corresponding section is set higher than the priority of the other sections, so that the section is selected as the playback section. Can be easy to be.

  Also, it is possible to change the time of the playback section once determined according to the favorite degree of content and the playback frequency. For example, a section with a high favorite level or a section with a high playback frequency is a section with a high priority, a section with a low favorite level (for example, a section not registered in the favorite section) or a section with a low playback frequency is a section with a low priority. By doing so, it can be made easy to select as a playback section.

  FIG. 3A is a schematic diagram showing an example of the digest playback section determined in this way. In the figure, when all the contents are song A and song B, the chorus parts p and s, the song parts q and t obtained from the incoming call setting information provided by the contents company, and the song interval Is determined as a playback section. Thereby, the music A and the music B can be reproduced without changing the reproduction speed. The incoming call setting information is prepared when content is provided, and includes, for example, rust information as time information (such as 3: 00-4: 00 is rust).

  FIG. 3B shows an example of changing the period for performing digest reproduction when the trigger generation in step S101 occurs due to another function of the mobile phone 1, for example, trick reproduction, resulting in a change in the remaining battery level. It is a schematic diagram which shows. In this figure, in addition to the skip section of the song B in FIG. 3A, the playback section is changed so that the chorus portion s is also skipped. As a result, even when a change occurs in the remaining battery level due to the operation of another function during digest playback, it is possible to play back songs A and B, which are all contents.

  The digest playback section determined in this way is notified to the playback control section 104 by the comparison section 102 as playback section information.

  In subsequent step S108, the condition detection unit 101 determines whether or not the battery 20 is being charged. As a result, when the battery 20 is not being charged, the playback control unit 104 controls the playback of content in the playback unit 40 based on the playback section information sent from the comparison unit 102 (step S109). At this time, the playback control unit 104 may control the playback unit 40 so as to fade in and fade out the joints of the playback sections.

  The playback unit 40 performs digest playback of all content under the control of the playback control unit 104 within a limited time associated with the remaining amount of the battery 20 (step S110), and ends the process.

  On the other hand, if it is determined in step S105 that all the current content can be reproduced within the remaining reproducible time, and if it is determined in step S108 that the battery 20 is being charged, the process proceeds to step S111. Skip to the procedure, play the content of all sections at normal speed (step S111), and end the process.

  According to such a playback section editing device 10, whether or not playback is possible is calculated by calculating the playback possible time from the remaining battery level and the like, and comparing this with the time required to play back the content stored in the storage medium 30. Determine whether. If it is determined that all the contents cannot be played back at the normal speed, the digest playback section is determined by obtaining the playable time for each content, and the determined digest playback section is played back. As a result, it is possible to reproduce all the content without changing the reproduction speed within the content reproducible time according to the remaining amount of the battery.

  Therefore, for example, if the playback unit 40 has not been started, playback can be performed because the remaining battery level is low or a viewing reservation is set on a DTV terminal or the like, rather than a trigger to start the playback unit 40 Time can be calculated and the digest playback section can be determined.

  Also, for example, when the playback unit 40 has already been activated, the remaining battery level is low or a viewing reservation is set on the DTV terminal or the like by other triggers (such as the above-described user action). The reproducible time can be calculated to determine the digest playback section.

  Furthermore, even after the digest playback section is once determined by the processing of FIG. 2 and the playback of the song is started, if the comparison unit 102 newly detects the occurrence of the trigger, the condition detection unit 101 Since the content reproducible time is calculated and the comparison unit 102 changes the digest playback section again, it is possible to perform content playback reflecting the latest situation of the mobile phone 1.

  In the present embodiment, the music data content in the mobile phone 1 has been described. However, the present invention is not limited to this, and the present embodiment can be similarly applied to video content in a DTV (digital television) terminal or the like. . The digest playback section in this case can be determined by detecting, for example, an exciting scene, a CM section, chapter information assigned to or associated with the content, and the like.

  INDUSTRIAL APPLICABILITY The present invention has an effect that all content can be reproduced without changing the reproduction speed when the reproduction time of the content is limited, and can be applied to a reproduction section editing device, an audio player, a mobile phone device, and the like. Useful.
