Description

  The present invention relates to a playback apparatus and playback method for playing back sound information recorded on a recording medium on which sound information is recorded.

  In recent years, in order to learn languages such as English conversation, CDs, cassette tapes, and other recording media on which audio information for learning is recorded have become widespread. The user learns by using these learning materials in which learning audio information is recorded and the included learning text.

  However, modern Japanese people tend to rely more on text if there are places where listening skills are extremely low compared to reading comprehension, so there are places where it is difficult to hear while playing the material. It is preferable to learn without looking at foreign language characters described in the text as much as possible. In addition, it is complicated to read the text each time to read the Japanese explanation, which results in a loss of learning time. Therefore, more efficient and effective learning is possible if the same learning can be performed without using text when learning the teaching material. Conventional language learning methods using CDs and cassette tapes have made it difficult to do similar learning without using text.

  Therefore, conventionally, there is a reproducing apparatus 1 that can reproduce an MP3 format file as shown in FIG. 1, for example. The MP3 format file has a header file and an audio file. In this playback apparatus 1, an MP3 format file recorded on a recording medium can be played back as an audio file format (3-track format) in which segments are classified by track using a header file. In the content using this file format, for example, each segment includes at least one word, track A has native speed audio information (eg, “Hello” in segment 1), and track B has slow speed audio. information (e.g., segment 1 "HELLO"), the track C includes a Japanese translation audio information (e.g., segment 1 "Hello"), the button operation of the reproducing apparatus 1, free of the same segment between tracks You can switch to and play. In this playback device 1, A button 6, B button 7 and C button 8 correspond to track A, track B and track C, respectively, and pressing any of A, B or C button will instantly track the track. You can switch and play. So, for example, if you play a segment of track A and the user feels it is too fast to hear at native speed, you can press B button 7 during or after playback without looking at the text. Switching to segment track B and listening to the same content at slow speed increases the likelihood of listening. Similarly, pressing C button 8 switches to Japanese translation of the same segment. Track C may contain not only Japanese translations but also audio information in Japanese. Therefore, by reproducing the content for language learning of the three-track system using the conventional reproducing apparatus 1, language learning can be effectively and efficiently performed without text.

  For example, when a three-track system content that memorizes English words is played back by the playback device 1, the user listens to the content repeatedly until it is memorized. However, the playback device 1 normally plays back the content in segment order. Therefore, in such a case, not only the segment that has not yet been memorized but also the segment that has already been memorized must be heard repeatedly, which is an inefficient learning method. It is possible to fast-forward a segment already memorized during reproduction and advance to the next segment, but the more the number of segments already memorized, the more complicated the operation becomes. 2. Description of the Related Art Conventionally, a program performance function used in a playback device such as a CD, that is, a function that allows a user to designate and play a track (a segment in the case of a three-track format) is known. Therefore, if this program performance function is adopted, it is considered that only segments that have not yet been memorized can be reproduced. However, even if such a program performance function is adopted in the playback apparatus 1, every time a segment that is memorized is generated, the user must select a segment that has not yet been memorized and set the program performance every time it is played back. In other words, very complicated work is required. There is a demand for a playback apparatus that can easily set a segment that has been memorized by the user and that can automatically skip the segment for playback. Further, when skipping an already memorized segment, it is preferable to simultaneously skip three segments associated by the three-track method.

  On the other hand, in Patent Document 1 below, a playback device applicable to playback of a recording medium in which a program with restrictions on playback (audio / video information) and a program that can be freely played back (audio / video information) are mixed, and A playback method is described. This reproducing apparatus is also an apparatus that can reproduce an audio file on a recording medium using a header file. In this playback apparatus, an identifier is automatically set during playback for a recording medium in which an identifier for determining whether each program is a playback-restricted program or a free playback program is recorded in a management area (header file). Can be determined automatically. Therefore, even if the user does not perform complicated settings such as program performance settings every time playback is performed, the playback-restricted program (that is, the program that the user wants to prohibit playback) can be automatically skipped for playback. Is possible. Therefore, if the skip playback method of the playback device disclosed in Patent Document 1 is adopted in the playback device 1, the device automatically stores the memorized identifier in the header file for the memorized segment of the memorized content. It is considered possible to perform skip reproduction.

JP 2002-175090 A

  However, the playback device disclosed in Patent Document 1 can automatically skip playback of audio information that is set to playback prohibition by determining the identifier recorded in the management area of the recording medium. However, basically, the user cannot change the identifier freely. However, when the playback is limited by the time limit, it is possible for the user to select playback prohibition (skip) by not setting the identifier (date information), but a complicated operation is required. Accordingly, there is a problem in the playback apparatus 1 that there is no apparatus and playback method that allow a user to skip a segment that the user wants to skip with a simple operation.

  Therefore, in view of the above circumstances, the present invention skips a desired segment with a simple operation by a user in a playback device for playing back a recording medium that records a file format in which segments are classified into tracks using a header file. It is an object of the present invention to provide a playback device and a playback method that can be set to perform skip playback.

  In order to solve the above problems, a playback apparatus according to the present invention plays back a recording medium having header information and audio information having a plurality of sections (segments) classified into a plurality of areas (tracks). A reproduction instructing means for the user to designate one of the areas to instruct reproduction, and an information acquisition means for reading information corresponding to a section of the area instructed to reproduce by the reproduction instructing means from the recording medium Voice information storage means for expanding and storing the information read by the information acquisition means as information in a reproducible format, and reproduction processing means for reproducing the information stored in the voice information storage means, Based on the audio information reproduced by the reproduction processing means, a skip setting means that can be set during reproduction so that the user does not reproduce the section next time; Provided, during reproduction, compartment set by the skip setting means characterized in that it does not play.

  With the above configuration, the user can perform skip setting while listening to the audio information of the segment, so that the memorized segment can be easily skipped during the next playback.

  In addition, a setting canceling unit for canceling the setting by the skip setting unit is provided.

  Further, the skip setting means skips all sections of the same classification as the set section.

  The skip setting means stores position information included in the header information corresponding to the set section in a skip information storage means provided in the playback apparatus.

  Further, the position information of the section set by the skip setting means is displayed on a display unit. Further, the skip setting means is a predetermined operation of a user performed during reproduction of a section.

  Further, the information acquisition means reads information from a recording medium detachable from the reproducing apparatus.

  Further, the information acquisition means reads information from a recording medium provided in the reproducing apparatus. The recording medium is a non-volatile memory.

  Furthermore, the reproduction method according to the present invention is a reproduction method for reproducing a recording medium having header information and audio information having sections classified into a plurality of areas, and the user uses a reproduction instruction means to The area is designated so that reproduction is instructed, information corresponding to a section of the area instructed to be reproduced by the reproduction instruction means is read from the recording medium, and the read information is expanded and reproduced. The information is stored in the voice information storage means, the information stored in the voice information storage means is reproduced by the reproduction processing means, and the user does not reproduce the section next time based on the voice information reproduced by the reproduction processing means. As described above, the skip setting is performed during the reproduction, and the skipped section is not reproduced during the reproduction.

  Therefore, according to the present invention, in a playback apparatus for playing back a recording medium in which a file format in which segments are classified for each track using a header file is played, a user can set a desired segment to be skipped by a simple operation, and skip A reproducing apparatus and a reproducing method capable of reproducing can be provided.

  Although FIG. 1 has been described as the playback apparatus 1 of the conventional example, this external view is the same in the playback apparatus according to the embodiment of the present invention, so that the same diagram is hereinafter used as the playback apparatus 1 according to the embodiment of the present invention.

  FIG. 3 shows a functional block diagram of the playback apparatus 1 in the first embodiment of the present invention. The playback device 1 includes a CPU 30, a ROM 31, a RAM 32, an EEPROM (or a non-volatile memory such as a flash memory) 33, an insertion unit 35, an information reading unit 36, an audio signal processing circuit 37, a headphone terminal unit 38, a display unit 41, and an operation unit 42. Have Among them, ROM 31, RAM 32, EEPROM 33, information reading unit 36, audio signal processing circuit 37, display unit 41, and operation unit 42 can send and receive signals and data to / from CPU 30 via bus 43, and are controlled by CPU 30. Yes. A recording medium 34 is connected to the insertion unit 35. Each function described in FIG. 3 indicates a function for reproducing an MP3 format file including an Lm format file. Therefore, descriptions of FM radio tuners, recording functions and the like are omitted.

  The ROM 31 is a non-writable mask ROM or an electrically rewritable flash ROM, in which various information is recorded. The ROM 31 stores, for example, a program necessary for developing an audio file stored in the recording medium 34 into the RAM 32.

  The RAM 32 is a memory that temporarily records information. The RAM 32 stores the audio information of the segment expanded into a reproducible format. The expanded audio information is then transmitted to the audio signal processing circuit 37.

  The EEPROM 33 is a rewritable nonvolatile memory, and can retain recorded information even when the apparatus is turned off. The EEPROM 33 has an area for storing address information of segments to be skipped. Based on this address information, skip playback can be performed in the memorization mode to be described later. The address information is managed for each content (Lm file) stored in the storage medium 34.

  The information reading unit 36 is a means for reading information recorded on the recording medium 34 set in the insertion unit 35. When the recording medium 34 is a non-volatile memory, information stored in the memory is voice-expanded in the RAM 32 based on a program recorded in the ROM 31 during reproduction. Further, the recording medium 34 may be a CD-ROM or a magnetic recording medium. In this case, the information reading unit 36 is a pickup device that detects information recorded on the recording surface thereof.

  The audio signal processing circuit 37 receives the digital audio signal expanded into the RAM 32 and applies a predetermined process to an analog signal. The headphone terminal unit 38 functions to output the analog signal to an external device such as headphones. Have

  The display unit 41 has a function for displaying information on the LCD 2 of the playback apparatus 1. For example, the file name, total number of segments, playback segment number, etc. of the Lm file included in the header file can be displayed. It is also possible to display the segment number set to skip. The operation unit 42 sends signals to the CPU 30 from switches under various buttons operated by the user.

  FIG. 4 shows a functional block diagram of the playback apparatus 1 in the second embodiment of the present invention. The playback device 1 includes a CPU 30, a ROM 31, a RAM 32, an audio signal processing circuit 37, a headphone terminal unit 38, a display unit 41, an operation unit 42, an I / F unit 44, and an EEPROM (or a nonvolatile memory such as a flash memory) 33. Among them, the ROM 31, the RAM 32, the audio signal processing circuit 37, the display unit 41, the operation unit 42, the I / F unit 44, and the EEPROM 33 can each transmit and receive signals and data with the CPU 30 via the bus 43, and are controlled by the CPU 30. ing. The I / F unit 44 is an interface for connecting to a terminal such as a PC connected to the Internet. As in FIG. 3, FIG. 4 shows a function for reproducing an MP3 format file including an Lm format file. Therefore, descriptions of FM radio tuners and recording functions are omitted.

  The ROM 31 is a non-writable mask ROM or an electrically rewritable flash ROM, in which various information is recorded. The ROM 31 stores, for example, a program necessary for expanding audio data stored in the EEPROM 33 to the RAM 32.

  The functions of the RAM 32, the audio signal processing circuit 37, the headphone terminal unit 38, the display unit 41, and the operation unit 42 are the same as those in the embodiment of FIG.

  The EEPROM 33 is a rewritable nonvolatile memory, and can retain recorded information even when the apparatus is turned off. The EEPROM 33 has an area for storing Lm files and an area for storing address information of segments to be skipped. Based on this address information, skip playback can be performed in the memorization mode. The address information is managed for each content (Lm file) stored in the storage medium 34.

  The I / F unit 44 is an interface for enabling connection between the PC and the playback apparatus 1. In the present embodiment, the Lm file is stored in the EEPROM 33 so as to be rewritable. For example, the Lm file is downloaded from the Internet to the PC, and the Lm file is sent from the PC to the playback apparatus 1. The Lm file data sent from the PC is stored in the EEPROM 33 via the I / F unit 44.

  FIG. 5 schematically shows the data structure of the Lm file stored in the storage medium 34 or the EEPROM 33. An Lm file consists of a header file and an audio file. The audio file is audio data in which each block is continuously arranged. Each segment has a different amount of data depending on the audio information contained therein, and each unit into which the segment is divided into n equal parts (the number of divisions is the same in any segment) is a block. It has 1 / n data volume of the original segment. Accordingly, the blocks in the same segment have the same amount of data. Further, the data amount of each block is obtained from the data amount of each segment and the division number n. Each block is assigned a segment number, a track number (for example, A, B, C), and a block number (1 to n), and immediately after the header file, SG (segment) 1: TR ( Track) -A: BL (block) 1, followed by SG1: TR-B: BL1, SG1: TR-C: BL1, and then proceeds to the next block number and becomes SG1: TR-A: BL2. Then, next to SG1: TR-C: BLn, the process proceeds to the next segment number and becomes SG2: TR-A: BL1. The start bit of each block is managed as address information in the header file. When each segment is expanded in the RAM 32, a designated block is called and combined based on address information for each block stored in the header file. The header file stores at least the file name of the Lm file, the number of tracks, the number of segments (m), the data amount of each segment, the number of segment divisions (n), and the like.

  The Lm file playback procedure in the embodiment of the present invention will be described with reference to the flowcharts of FIGS. In step S1, the mode button 5 is pressed to select a mode such as MP3 mode, Lm mode, and FM radio. Each time the mode button 5 is pressed, these modes can be set in a predetermined order. If the Lm mode is selected, the process proceeds to step S2, and the Lm mode is set. In step S3, if content is to be selected, the process proceeds to step S4. If it is desired to end the Lm mode or no operation is performed for a predetermined time, the process proceeds to step S9. In step S4, the user performs an operation of selecting content (Lm file) to be reproduced from the recording medium 34 or the EEPROM 33. When the content is selected, the process proceeds to step S5. In step S5, the user selects a playback mode. That is, the user selects whether to play the Lm file in the normal playback mode or in the memorization mode according to the embodiment of the present invention. If it is desired to select the memorization mode, the process proceeds to step S6, the memorization mode is set, and then the process proceeds to step S7.

  In step S7, a playback track is selected. Here, playback is performed in the order of A track → B track → C track for each segment (track order playback), or the main track is designated and the segments of the track are continuously played. You can select whether to play (main track playback). In addition, it is possible to specify a segment to start playback using the FF button 10 and the REW button 11. When track order playback is selected, playback is performed in the order of A → B → C track of the specified segment (segment 1 if not specified, hereinafter referred to as playback specified segment), and A → B → C track of the next segment. . In other words, the user can listen in the order of a word of native pronunciation → a word of slow speed pronunciation → a Japanese translation. When the main track reproduction is selected, for example, when the A track is designated, the reproduction designation segment of the A track is reproduced in the order of the next segment of the A track. By pressing the B button or the C button during playback, the playback can be switched to the B track or C track of the segment being played back (detailed later). When the reproduction track selection in the memorization mode is performed in step S7, the process proceeds to step S8.

  In step S8, as will be described in detail later, in the case of track order reproduction, the reproduction method shown in FIG. 7 is used, and in the case of main track reproduction, the reproduction method shown in FIG. 8 is used. When the reproduction ends, the process proceeds to step S9. When it is desired to end the Lm mode (step S9: YES), the process proceeds to step S10. When it is desired to reproduce the content without ending the Lm mode (step S9: NO), the process returns to step S3. In step S10, the apparatus can be turned off by pressing the power button 4 or not operated for a predetermined time (step S10: YES), and can return to step S1 by a predetermined operation. .

  FIG. 7 shows the processing in step S8 when the reproduction method in the track order is selected in step S7 in FIG. In step S20, if the reproduction designated segment has already been skipped (step S20: YES), the process proceeds to step S36. If the skip setting is not made (step S20: NO), the process proceeds to step S21. With this configuration, the playback apparatus can automatically play back the segment memorized by the user. In step S21, reproduction is performed from the A track of the reproduction designated segment. If segment A playback or repeat playback is requested by the A button 6 or REW button 11 during segment playback (step S22: YES), the process returns to step S21 and the segment is played back from the beginning. If there is no request for replay (step S22: NO), the process proceeds to step S23. In step S23, if the user wishes to skip the segment during the next playback during playback of the A track (step S23: YES), the process proceeds to step S24 and skip setting is performed. When the segment is not skipped at the next playback (step S23: NO), the process proceeds to step S25. In step S24, by pressing the record button 9 (or the mode button 5) during playback of the segment, the segment is set as a segment to be skipped next time. After the setting, the process proceeds to step S25, and the reproduction of the A track of the reproduction designated segment is completed.

  After completion of the reproduction in step S25, reproduction of the B track of the same segment starts in step S26. If segment B playback (repeat playback) is requested by the B button 6 or REW button 11 during segment playback (step S27: YES), the process returns to step S26 and the segment is played back from the beginning. If there is no request for replay (step S27: NO), the process proceeds to step S28. In step S28, if the user wishes to skip the segment during the next playback during playback of the B track (step S28: YES), the process proceeds to step S29 and skip setting is performed. When the segment is not skipped at the next playback (step S28: NO), the process proceeds to step S30. In step S29, by pressing the recording button 9 (or the mode button 5) during playback of the segment, the segment is set as a segment to be skipped next time. After the setting, the process proceeds to step S30 and the reproduction ends.

  After completion of the reproduction in step S26, reproduction of the C track of the same segment starts in step S31. If segment C playback or repeat playback is requested by the C button 6 or the REW button 11 during segment playback (step S32: YES), the process returns to step S31 and the segment is played back from the beginning. If there is no request for replay (step S32: NO), the process proceeds to step S33. In step S33, if the user wishes to skip the segment during the next playback during playback of the C track (step S33: YES), the process proceeds to step S34 and skip setting is performed. When the segment is not skipped at the next playback (step S33: NO), the process proceeds to step S35. In step S34, by pressing the recording button 9 (or the mode button 5) during playback of the segment, the segment is set as a segment to be skipped next time. After the setting, the process proceeds to step S35 and the reproduction ends.

  The skip setting in steps S24, S29, and S34 is performed by pressing the recording button 9 or the like at the time of playback, so that the address of the segment being played (all the A, B, and C tracks of the segment can be selected even if any track is selected). Is stored in a predetermined area of the EEPROM 33, and in the next playback (memorization mode), the audio information is expanded from the Lm file of the storage medium 34 or the EEPROM 33 to the RAM 32 for the segment of the stored address. It is done by not doing. As a result, those segments are not reproduced at the next reproduction. The address information of the skip-set segment stored in a predetermined area of the EEPROM 33 is managed and stored for each content. Since the EEPROM 33, which is a non-volatile memory, retains information even when the power is turned off, the skip setting is maintained when the power is turned on next time and the content is reproduced. The processes from step S22 to step S24 are all performed during the reproduction of the reproduction designated segment of the A track, and the processes from step S27 to step S29 are all carried out during the reproduction of the reproduction designated segment of the B track. The processes from step S32 to step S34 are all performed during the reproduction of the reproduction designated segment of the C track. Therefore, the user can set the skip while listening to the audio of each playback specified segment or during playback of the silent part after the end of the audio in the segment. Can be set instantly.

  In step S36, when the reproduction of all the tracks A, B, and C of the reproduction designated segment is finished, if the user does not press the stop button (power button 4) or the like (step S36: YES), the process proceeds to step S37. When the stop button or the like is pressed (step S36: NO), the track order reproduction process ends, and the process proceeds to step S9 (FIG. 6). In step S37, if the segment that has been reproduced is the last segment of the content (Lm file) (step S37: YES), the track order reproduction process is terminated, and the process proceeds to step S9 (FIG. 6). . If it is not the last segment (step S37: NO), the segment is incremented by one and the process returns to step S20. Note that the user can end the process by pressing a stop button or the like at any timing between step S20 and step S35. Also in this case, the process proceeds to step S9 (FIG. 6).

  FIG. 8 shows the processing in step S8 when main track playback is selected in step S7 of FIG. After designating the main track in step S7 (designated by the A, B, C buttons 6, 7, 8), the process proceeds to step S50. In step S50, if the playback designated segment has already been skipped (step S50: YES), the process proceeds to step S60. If the skip setting is not made (step S50: NO), the process proceeds to step S51. With this configuration, the playback apparatus can automatically play back the segment memorized by the user. In step S51, reproduction of the designated reproduction segment of the designated track is started. Although FIG. 8 shows the case where the main track is the A track, even if the main track is set to the B or C track, the basic process does not change because only the button is changed, and the description thereof is omitted. . If replay (repeat playback) is requested by the A button 6 or the REW button 11 during playback of the designated segment of the A track (step S52: YES), the process returns to step S51 and the segment is played back from the beginning. . If there is no request for replay (step S52: NO), the process proceeds to step S53. If it is desired to listen to another track (B track or C track) during playback of the A track (step S53: YES), the process proceeds to step S54. In step S54, when the user presses the B button 7 (step S54: B), the process proceeds to step S55, and the B track of the same segment is reproduced. In step S54, when the user presses the C button 8 (step S54: C), the process proceeds to step S56, and the C track of the same segment is reproduced. When the reproduction in step S55 or step S56 is completed, the process returns to step S52.

  If no other track is heard in step S53 (step S53: NO), the process proceeds to step S57. In step S57, if the user wishes to skip the segment during the next playback during playback of the A track (step S57: YES), the process proceeds to step S58 and skip setting is performed. When the segment is not skipped at the next playback (step S57: NO), the process proceeds to step S59. In step S58, by pressing the record button 9 (or the mode button 5) during playback of the segment, the segment is set as a segment to be skipped next time. After the setting, the process proceeds to step S59, where the reproduction of the A track of the reproduction designated segment is completed. After the reproduction ends, the process proceeds to step S60.

  In step S58, the skip setting is performed by pressing the recording button 9 or the like during playback, so that the address of the segment being played back (along with the selection of the A track and the addresses of the B and C tracks) is stored in the predetermined EEPROM 33 The data is stored in the area, and at the next reproduction (memorization mode), the segment of the stored address is performed by not expanding the audio information from the Lm file of the storage medium 34 or the EEPROM 33 to the RAM 32. . As a result, the skip segment is not reproduced at the next reproduction. The address information of the skip-set segment stored in a predetermined area of the EEPROM 33 is managed and stored for each content. Since the EEPROM 33, which is a non-volatile memory, retains information even when the power is turned off, the skip setting is maintained when the power is turned on next time and the content is reproduced. Further, the user can perform skip setting while listening to the sound of each reproduction designated segment or during the reproduction of the silent portion after the sound in the segment ends. Therefore, the user can instantaneously skip the memorized segment with a simple operation.

  In step S60, if the user does not press the stop button (power button 4) or the like (step S60: YES), the process proceeds to step S61. When the stop button or the like is pressed (step S60: NO), the main track reproduction process ends, and the process proceeds to step S9 (FIG. 6). In step S61, if the segment that has been reproduced is the last segment of the content (Lm file) (step S61: YES), the main track reproduction process is terminated, and the process proceeds to step S9 (FIG. 6). . If it is not the last segment (step S61: NO), the segment is increased by one and the process returns to step S50. The user can end the process by pressing a stop button or the like at any timing between step S50 and step S59. Also in this case, the process proceeds to step S9 (FIG. 6).

  Further, during step S8 in FIG. 6 (that is, during the processing in FIG. 7 or FIG. 8), the user can perform various settings by pressing the menu button 13 at an arbitrary timing. For example, with respect to the segment to be displayed on the LCD of the display unit 2, it is possible to select a normal display for displaying the segment currently being played back, a skip segment display for displaying only the segment set to be skipped, or the like. When it is desired to restore the skipped segment, the menu button 13 can be pressed and then the skip all cancel can be selected. In this skip all cancel, it is possible to cancel all the skip settings of the segments in the selected content. That is, this is done by erasing the address stored in the RAM 32 for skip setting.

  Therefore, according to the present invention, in a playback apparatus for playing back a recording medium in which a file format in which segments are classified for each track using a header file is played, a user can set a desired segment to be skipped by a simple operation, and skip A reproducing apparatus and a reproducing method capable of reproducing can be provided.
