TECHNICAL FIELD OF THE INVENTION
The present invention relates to a media player.
[Prior art]
[0002]
There are many media players for playing music and movies, regardless of software and hardware. All of them are designed with a view to playing media files for entertainment. However, CDs, DVDs, and MDs can be used not only for music and movies but also for learning, and English word CDs for learning have already been released. Further, these media players and the like have various functions for enjoying music and moving images, such as program reproduction and random reproduction. In recent years, liquid crystal display panels have become inexpensive, and a function of playing a MP3 or the like on a CD player at the same time has been added, so that a display device can display more detailed information. At the same time, the diversity of program playback is beginning to be seen. In addition, software media players used in computers and PDAs can be controlled by a pointing device such as a mouse or pen, and have a large display area, so that playlists can be edited more easily. It has additional functions.
[Problems to be solved by the invention]
[0003]
It has been more than 20 years since the first devices with random access media players were completed, but the functions and user interface of these media players were determined from the viewpoint of enjoying music and movies, and these were used for learning. Lack of perspective for use. For example, when a CD is used for memorizing words, it is troublesome to skip words that have already been memorized each time a track is reproduced, and it becomes impractical as the number of tracks increases. The number of tracks on a CD is limited to 99. For example, in a CD in which 1000 words are recorded, 100 or more words must be recorded on one track, and skipping is not appropriate. Sometimes I have to ask me many times. Software media players used for computers and PDAs can edit specific playlists to prevent playback of specific media files, but the user interface is designed from the perspective of selecting the songs that you want to listen to. It takes a lot of trouble to remove songs you don't want to listen to from the playlist, and you can delete songs that are currently being played from the playlist with one button and skip at the same time. No user interface. For example, in a Windows Media player of Microsoft Corporation, which is a typical software media player, in order to delete a song being played from a playlist, the song being played is pointed out again with a pointing device such as a mouse, and a mouse is used. Right-click or press the delete button and select "Delete from playlist" from the menu that appears.Press the fast forward button to skip the song that continues to play even if deleted, or select the next song in the playlist. A series of operations such as double-clicking directly with the mouse was required. As a method of specifying a song that the user does not want to listen to, it is not a practical method, especially in a moving train. With a simple operation, you can skip the playback of tracks that you no longer need to listen to, and if the media player saves information even when the media is switched or the power is turned off, for example, a CD used for learning words Since the number of tracks to be reproduced decreases as the learning progresses, the number of times that a word not yet remembered is heard per unit time increases, and efficient learning can be expected.
[0004]
[Means for Solving the Problems]
In the media player according to the first aspect, the media player is configured to play a media file based on a play list. The media player includes a storage unit and a reproduction stop media file designating unit, and the play list is recorded in the storage unit. When the user designates the media file by the playback stop media file designating unit during the reproduction of the specific media file, the control program mounted on the media player or the media player program is executed for the media file being reproduced. Is moved from the play list being played, and at the same time, the playback of the next media file is started from the media file. Thereafter, when the reproduction is performed based on the reproduction list, the reproduction of the media file is skipped.
[0005]
In the media player according to the second aspect, the media player is configured not to play the registered media file. When the media file is designated by the playback stop media file designating unit while the media file is being played, the media file information is registered in the storage unit by the control program or the media player program mounted on the media player. At the same time, the process proceeds to playback of the next media file from the media file. Thereafter, the reproduction of the media file is always skipped.
[0006]
Further, it may be a media player program having the functions described in claims 1 and 2.
[0007]
BEST MODE FOR CARRYING OUT THE INVENTION
In this specification, a medium refers to a medium storing a media file such as a CD, a DVD, an MD, a memory card, a memory stick, and a hard disk, and a media file refers to a moving image, audio data, and the like. , WMA, etc. These data are often called tracks in CDs and MDs, but in the present invention, a single moving image and audio file are all called media files for convenience. For example, data (for example, 100 words) divided into a plurality of portions in a single track (media file) of a CD is also treated as a single media file for convenience.
[0008]
In a system using a music CD, MD, or the like, one piece of music is recorded as one track of audio data, and management information called TOC (Table of contents) is recorded on a medium. In the TOC, the address of the recording position is managed for each track number. In many cases, the address is unique to each medium and can be used as medium identification information. In addition, in a memory stick, a memory card, a data CD, and the like, there are various kinds of information unique to a medium, such as a capacity and a volume label, and these can be used as medium identification information. If it is necessary to individually identify, for example, data CDs inserted into the media player, these may be used alone or in combination.
[0009]
In order to specify a media file, for a replaceable medium, a method of specifying a “specific track of a specific medium” using the identification information described in the preceding paragraph such as the TOC, or information unique to the media file can be used. There are many methods for specifying the file name, file size, all or part of digital data, and features extracted from them. When a single track is divided into a number of parts on a CD, if the designation "specific track of a specific CD" is not appropriate, the digital data of the first and second parts of the file and the address information itself on the CD medium Can be used as recognition information. What is called media file information in the present invention indicates these.
[0010]
Hereinafter, embodiments of the present invention will be described with reference to the drawings. The figures and methods are only examples, and do not restrict the method of actual implementation.
[0011]
An embodiment of the present invention in a media player capable of exchanging media will be described. FIG. 1 shows a portable CD / MP3 player. It is assumed that the main body can be loaded with a music CD or a data CD, and has a nonvolatile memory as a storage means. The main body has a liquid crystal display unit 10, a play button 11, a stop button 13, a fast forward button 14, a rewind button 12 mounted on a normal CD / MP3 player, and a user interface of the present invention. A non-reproduction designation button 15 is provided. The control software is configured to play a play list associated with the medium when the medium is loaded by the user and the play button 21 is operated, and to automatically generate a play list when there is no play list. . If the user presses the non-playback media file designation button 25 during playback of a media file having a play list associated with the media, the media file information is deleted from the play list, and playback of the next media file is started. Thereafter, when the medium is loaded, the reproduction is performed based on the associated reproduction list, and the reproduction of the media file is not performed.
[0012]
Next, a description will be given of an embodiment of the software media player according to the first and third aspects in which a nonvolatile memory is mounted as a storage means. FIG. 1 is an example of a screen during reproduction of a software type media player operating on a PDA equipped with a nonvolatile memory. An OS, a media file, a media player program, and the like are stored in a nonvolatile memory of the PDA, and the media file is configured to be reproduced based on a reproduction list. The playlist can be freely edited by the user, and the media file and the media file in the playlist can have a one-to-many relationship.
[0013]
It is assumed that a media player program is running on the PDA. FIG. 1 shows that the media file “150” in the list “English syntax 1700” is being played. When the non-playing designation media file designation icon 24 is tapped by the user, the media player moves “150” from the playlist “English syntax 1700” to the non-playing list. At the same time, the reproduction of the media file being reproduced is stopped, and the process proceeds to the reproduction of the next media file “151”. Thereafter, since there is no media file information in the play list, "150" is not played in the play based on the play list.
[0014]
Next, a media player according to a second aspect will be described. The media player is configured not to play the media file registered in the recording means. Referring to FIG. 2 and the flowchart of FIG. 3, when the play button 11 is operated in the media player of FIG. 2, the control software acquires the n-th media file information, and Is searched for (S14), and if there is a match with the media file information, the playback is skipped (S13) and the process proceeds to the next media file playback. If the information of the media file to be reproduced is not recorded in the storage means, the reproduction is performed as it is (S15). When the reproduction of the music ends, the step of S14 is performed again before the reproduction of the next music. When a non-reproduction designation button is operated during reproduction of a certain media file, reproduction of the media file being reproduced is stopped, the media file information is recorded in the recording means, and at the same time, reproduction of the next media file is started. The control program according to the flowchart shown in FIG. 3 is suitable for a media file such as MP3 that can give a specific file name to the media file.
[0015]
When the medium is a medium such as a CD or MD and the media file does not have a file name, it may be more efficient to acquire the information of the medium first than to perform the method described above. That is, as shown in the flowchart of FIG. 4, when the play button 11 is operated, the software mounted on the main body acquires the information of the medium and determines whether or not the information of the medium is registered in the recording means. Is searched (S22), and if it is registered, the setting is made to skip the reproduction of the registered media file of the media (S23). If it is not registered, it is appropriate to adopt a method of reproducing as usual (S24).
[0016]
Various methods can be considered in S23. For example, TOC information for setting not to reproduce a registered media file for a specific medium is stored, and when the loaded medium is a registered medium, It is also effective to replace the stored TOC information.
[0017]
In the method of registering the media file itself, in order to acquire information of the media file itself, if the same media file is recorded on different media, the same media file can be reproduced even if the media is exchanged. On the other hand, when the medium is a CD or MD, there is a disadvantage that the information acquisition means, recording, and retrieval means are slightly complicated. This is not limited to a media file such as a data CD or a memory stick and a media file such as MP3 having a data structure capable of storing various information in the file itself. Therefore, as shown in the flowchart of FIG. 3, it is effective not to use the above methods at all but to use them in combination depending on the media type.
[0018]
Further, the media player of the present invention can be realized by the method as shown in the flowchart of FIG. 3 for the media player of claim 2 which realizes the software media player of claim 3 on a PDA or the like.
[0019]
When the medium is a CD and playback of one of a plurality of media files in a track is stopped, a silent portion before and after the designated portion is detected, and a portion sandwiched between the silent portions is detected. Is set as a playback stop media file. In this case, as pointed out above, it is effective to replace the TOC information of the medium and reproduce the TOC information.
[0020]
Further, the configurations in the above-described drawings and the methods shown in the flowcharts are merely examples, and the media player of the present invention can be realized by other methods and configurations. Further, in the present specification, the order of skipping the media file being reproduced and registering the media file or moving the media file from the reproduction list may be performed in the control program and the media player program. The playback stop media file designating means can be emulated even in a conventional media player having only keys by, for example, simultaneously pressing two keys, a fast forward key and a rewind key. Needless to say, it is necessary to provide a means for enabling the reproduction of the stopped media file.
【The invention's effect】
By using the media player of the present invention, it is possible to make settings so that songs that one does not want to hear or media files that do not need to be heard are not easily reproduced.
