TECHNICAL FIELD OF THE INVENTION
The present invention relates to a data reproducing apparatus and an error file processing method, and more particularly to a processing method when a file error occurs during reproduction of audio data or image data recorded in a file unit and reproduction becomes impossible.
[0002]
[Prior art]
Some recent audio reproducing apparatuses have a function of sequentially reproducing music data in which each music piece is recorded on a recording medium in file units. As typical music data recorded in file units, there is a music file in which a digital music source is compressed according to a format such as MP3 (MPEG-Audio-layer 3) or ATRAC3 (Adaptive Transform Acoustic Coding 3).
[0003]
Conventionally, in this type of audio playback device, if playback of the file cannot be continued in the middle because the file to be played is damaged or the like, an error message is displayed at that point and playback of the file is stopped. Had been done. Note that a technique for restoring a recorded file until the power is cut off and the recording is stopped unexpectedly when the power supply is unexpectedly stopped while the file is being recorded on the recording medium is disclosed in, for example, Patent Document 1. Have been.

[Problems to be solved by the invention]
However, in the above-described conventional technology, when playback is stopped due to a file error, the user has to operate a skip button, a play button, and the like in order to skip a damaged file and resume playback from the next file. And there was a problem that it was very troublesome.
[0006]
Further, at the time of next reproduction (for example, when reproduction is started from the beginning of the recording medium), there is a problem that a file error occurs at the same place as the previous time and reproduction is stopped. In order to avoid this, when the reproduction is stopped due to a file error, there is a problem that a complicated operation of calling a track number corresponding to the file and deleting the file must be performed.
[0007]
The present invention has been made in order to solve such a problem, and in a case where reproduction becomes impossible due to a file error, the same file error does not occur at the next reproduction without any troublesome operation. The purpose is to be.
It is another object of the present invention to enable the user to enjoy the reproduction without troublesome operation even when the reproduction becomes impossible due to a file error.
[0008]
[Means for Solving the Problems]
In order to solve the above-described problem, according to the present invention, when reproduction cannot be continued due to a file error, the user is notified that reproduction is not possible, or at the same time or subsequent to this, the error occurs. The file is deleted. This makes it possible to delete the unplayable file in real time during the playback operation.
[0009]
Further, in another aspect of the present invention, when the reproduction cannot be continued due to a file error, the file in which the error has occurred is deleted and the reproduction is started from a file different from the file. . This makes it possible not only to delete unplayable files in real time during the playback operation, but also to automatically proceed to an error-free file and play it without operating the skip button or play button. It is possible to do.
[0010]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a block diagram showing a functional configuration of an audio reproducing apparatus 100 that implements a data reproducing apparatus according to the present invention.
[0011]
As shown in FIG. 1, an audio reproducing apparatus 100 according to this embodiment includes a microcomputer (microcomputer) 1, a memory interface (I / F) 2, a display driver 3, a display 4, a key operation unit 5, an MPEG decoder 6, A / A converter (DAC) 7, an amplifier 8, a speaker 9, and a position information storage unit 10 are provided.
[0012]
The microcomputer 1 controls the entire audio reproducing apparatus 100 (memory I / F 2, display driver 3, key operation unit 5, MPEG decoder 6, and position information storage unit 10). The memory I / F 2 exchanges compressed audio data and control data between the microcomputer 1 and the memory card 200 that stores, for example, compressed audio data in MP3 format.
[0013]
The compressed audio data recorded on the memory card 200 is formed of a different file for each music piece. One track is formed by one music file. As shown in FIG. 2, each track is composed of a set of blocks which are basic units used in so-called resume play (reproduction from the position where the track was stopped last time).
[0014]
The display driver 3 displays various information including a playback state (playback track number, playback time, playback mode, volume, remaining battery level, etc.) on the display 4 under the control of the microcomputer 1. The display driver 3 also displays on the display 4 an error message when the microcomputer 1 detects a file error, a confirmation screen for inquiring the user whether or not to delete the file, and the like.
[0015]
The key operation unit 5 is for the user to give various instructions to the audio reproducing device 100. The key operation unit 5 includes a reproduction key, a stop key, a skip (track Up / Down) key, a volume operation key, a mode designation key, and the like. By operating the key operation unit 5, the user can specify whether or not to delete the file in which the error has occurred.
[0016]
For example, it is possible to assign two keys (which may be shared with other functions) to the presence or absence of file deletion, and specify whether or not to delete the file by operating one of them. It is. Alternatively, the key operation unit 5 may be configured by a touch panel display, and the presence or absence of file deletion may be designated by operating keys displayed on the display.
[0017]
The MPEG decoder 6 expands the compressed audio data taken from the memory card 200 through the memory I / F 2 under the control of the microcomputer 1 to generate audio data. The D / A converter 7 converts audio data output from the MPEG decoder 6 into an analog audio signal. The amplifier 8 amplifies the analog audio signal output from the D / A converter 7 by a predetermined amount and outputs the amplified signal from the speaker 9.
[0018]
The position information storage unit 10 stores information relating to the reproduction position of the music file under the control of the microcomputer 1. That is, the microcomputer 1 manages the playback position of the memory card 200 mounted on the audio playback device 100, and stores the track number currently being played back, the block number therein, and the like in the position information storage unit 10.
[0019]
When there is no file error such as damage in the compressed audio data recorded on the memory card 200, the audio reproducing device 100 configured as described above operates as follows. That is, when a reproduction instruction is issued by operating the key operation unit 5, the microcomputer 1 reads out compressed audio data from the memory card 200 through the memory I / F2.
[0020]
The compressed audio data read from the memory card 200 is supplied to the MPEG decoder 6. The MPEG decoder 6 expands the input compressed audio data to generate audio data. The audio data generated by the MPEG decoder 6 is supplied to a D / A converter 7.
[0021]
The D / A converter 7 converts the input audio data into an analog audio signal. The analog audio signal thus generated is output from the speaker 9 via the amplifier 8. During such a series of reproduction operations, the microcomputer 1 stores the track number indicating the reproduction position of the music file, the block number therein, and the like in the position information storage unit 10.
[0022]
FIG. 3 is a flowchart showing an operation when accessing a corrupted file that cannot be reproduced for some reason while a music file is being reproduced in accordance with the above operation. For example, if the 10th block is damaged during playback of the music file of the first track with respect to the compressed audio data shown in FIG. 2 and playback cannot be continued further, the flowchart shown in FIG. 3 is executed. You.
[0023]
In FIG. 3, the microcomputer 1 controls the display driver 3 to display an error on the display 4, thereby notifying the user that the file is damaged and cannot be reproduced (step S1). Next, the microcomputer 1 controls the display driver 3 to display a confirmation screen as shown in FIG. 4 on the display 4, thereby inquiring the user as to whether or not to delete the file in which the error has occurred (step S2).
[0024]
In response, the user operates the key operation unit 5 to specify whether to delete the error file. Here, when the user instructs to delete the error file, the microcomputer 1 outputs control data to the memory I / F 2 and deletes the error file from the memory card 200 (Step S3). The file in which the error has occurred is grasped by referring to the position information storage unit 10 (the track number at the time when the reproduction is stopped is stored in the position information storage unit 10).
[0025]
After deleting the error file in step S3, the microcomputer 1 controls to move to the next music piece and play it by specifying the track number next to the track number stored in the position information storage unit 10. (Step S4). If the user does not instruct the deletion of the error file in step S2, the process proceeds to the next music piece without deleting the file and reproduces it (step S4).
[0026]
As described above in detail, according to the present embodiment, when an error occurs during reproduction of a music file and the reproduction becomes impossible, the user can be notified that the reproduction is impossible. Further, by simply instructing file deletion in accordance with a confirmation screen provided in real time when an error occurs, the unplayable file can be deleted. Therefore, the same error can be prevented from occurring at the next reproduction without performing a complicated operation. Furthermore, according to the present embodiment, the next song is automatically played back after instructing whether or not to delete a file, so that there is no need to perform a complicated operation for restarting playback, and user convenience is improved. Can be improved.
[0027]
In the above embodiment, a music file in the MP3 format is described as an example of the compressed music data recorded on the memory card 200, but the compression format is not limited to this. For example, a compression format such as ATRAC3, AAC (Advanced Audio Coding), AC-3 (Dolby Digital), TwinVQ, or WMA (Windows Media Audio) may be used.
[0028]
In the above embodiment, the reproduction of a music file is described as an example, but the present invention can be applied to the reproduction of an image file. For example, when sequentially reproducing a plurality of still image files, if a certain file is damaged and cannot be reproduced, the same processing as the flowchart shown in FIG. 3 can be performed. The same applies to the case of sequentially reproducing a plurality of moving image files.
[0029]
Further, in the above embodiment, the memory card 200 is used as an example of the recording medium, but the present invention is not limited to this. For example, a CD-ROM, a flexible disk, a hard disk, a magnetic tape, an optical disk, a magneto-optical disk, or the like can be used.
[0030]
Further, in the above-described embodiment, an example has been described in which, when an error occurs in a certain file, the reproduction is started from the next file. However, the file need not always be the next file. For example, the reproduction may be started from a randomly selected file excluding the error file, or the reproduction may be started from the first file.
[0031]
Further, in the above embodiment, when the deletion of the error file is instructed, the corresponding file is simply deleted. However, the deleted track number is stored, and the music file of the track number is stored in the next reproduction. The deletion may be displayed on the display 4 to notify the user.
[0032]
In addition, the above-described embodiment is merely an example of the embodiment of the present invention, and the technical scope of the present invention should not be interpreted in a limited manner. That is, the present invention can be embodied in various forms without departing from the spirit or main features thereof.
[0033]
【The invention's effect】
As described above, according to the present invention, when data reproduction cannot be continued due to a file error, the error file is deleted. Therefore, the error file is deleted in real time during the reproduction operation. With the simple operation, the same error can be prevented from occurring at the next reproduction.
[0034]
According to another aspect of the present invention, when data reproduction cannot be continued due to a file error, reproduction is started from a file different from the error file, so that the user can perform complicated operations. Even if it is not performed, playback can be continued from another file.
