Description

  The present invention relates to an optical disk playback apparatus equipped with a hard disk, and more particularly to setting of playback parameters and recording processing during optical disk playback.

  In recent years, as an apparatus for reproducing video and audio processed in a video apparatus such as a television, a digital optical disk reproducing apparatus such as a DVD (Digital Versatile Disk) player has been widely used. One of the functions of these digital optical disc playback apparatuses is a resume function.

  The resume function is a function for automatically starting playback from the previous playback stop position at the next playback after playback stop, for example, in an optical disc recording / playback apparatus or the like. Specifically, when the optical disc recording / playback apparatus receives a playback stop instruction from the user, the playback stop position on the optical disc is detected, and a pointer indicating the detected playback stop position is recorded as the next playback start point (resume point). To do. By using this function, when a playback start instruction is received again after playback stops, it is possible to perform continuous playback from the position where playback was previously stopped by referring to the stored resume point. is there.

  One of the functions of the digital optical disk playback apparatus is a playback parameter setting function. The playback parameter setting function, for example, when playing an overseas movie (foreign film), selects the sound (Japanese or English, etc.), and displays / hides subtitles (Japanese translation) This is a function for setting a playback parameter used for performing the above. Normally, the reproduction parameter is set by a user giving an instruction using an operation device such as a remote controller.

  For example, in a DVD player, it is possible to record a maximum of eight languages of audio and a maximum of 32 languages of subtitles on a single storage medium (DVD medium). When playing back content recorded on a DVD medium, it is possible to play back audio and subtitles in any combination. Thus, the viewer can set the audio and subtitles to be reproduced according to his / her preference (reproduction parameter setting) and view the audio and subtitles.

  However, in the conventional DVD player, when the DVD medium is exchanged after setting the reproduction parameters, the reproduction parameters are reset to the initial parameters (reproduction parameters set at the time of shipment from the factory) or before the exchange. There is a problem that reproduction is performed based on the reproduction parameters of the DVD media. For example, it is assumed that a DVD medium on which a foreign movie has been recorded is set to a reproduction parameter so that the DVD medium is reproduced with English audio and Japanese subtitles, and then is replaced with a DVD medium on which a Japanese movie is recorded. In this case, unless the playback parameter setting is changed, a new DVD medium (a DVD medium on which a Japanese movie is recorded) is played back with English audio and Japanese subtitles. For this reason, the user has to change the playback parameters every time the DVD medium is replaced, which increases the work load.

  In relation to the above problem, Patent Document 1 discloses a recording medium playback device aimed at reducing the operation burden for setting parameters of dubbed audio and subtitles for each DVD medium. The recording medium playback apparatus of Patent Document 1 has selection control means controlled based on predetermined parameters, reads a plurality of data associated with the same playback time from the recording medium, and performs the selection control on the read data. Select and play by means. Then, the parameters of the selection control means are stored in association with a plurality of contents, the contents of the recording medium are identified, the parameters stored in association with the identified contents are read, and the contents of the contents are read using the read parameters. It is characterized by playing.

  According to the invention of the above-mentioned Patent Document 1, the content recorded on the recording medium is identified, and various control processes are performed using the reproduction parameters stored in advance in association with the identified content. In addition, it is possible to reduce the operation burden for setting the parameters of subtitles.

  In relation to the above problem, Patent Document 2 discloses a reproduction method that can appropriately set reproduction parameters when reproducing a recording medium such as a DVD medium. In the reproduction method of Patent Document 2, when reproducing content recorded on a predetermined recording medium (DVD media or the like), selectable reproduction parameters for the content to be reproduced on the attached recording medium are read. When the same playback parameter is stored, the playback parameter is used for playback. If no playback parameters are stored, a list of playback parameters that can be selected is displayed.

According to the above-mentioned patent document 2, when the same content has been played in the past, the playback is performed by automatically setting the playback parameters at the time of playback. As a result, when the content once subjected to the reproduction parameter is reproduced again, since the previous reproduction parameter is stored, the optimum reproduction parameter setting for the content can be automatically performed. Further, in the case of content that has not been played back in the past, a list of playback parameters that can be selected is displayed, from which playback parameters are selected. As a result, even when a recording medium that has not been set with playback parameters before is played back, the playback parameters can be easily set with the selection screen.
JP 2001-6330 A JP 2005-129171 A

  However, in the recording medium playback apparatus and the playback method disclosed in Patent Document 1 and Patent Document 2, since a memory (RAM) is used as a medium for storing playback parameter settings, playback parameter settings that can be stored There was a problem that the number of was small. Therefore, when there are many DVD media to be played back, it is necessary to erase the old playback parameter settings in order.

  In addition, when a single DVD medium is viewed by a plurality of users, a certain user temporarily stops viewing the contents of the DVD medium (for example, when the DVD medium is temporarily removed from the playback device). In addition, when another user tries to view the content of the DVD medium, the reproduction is performed with the reproduction parameter set by the other user. Therefore, the user must set the reproduction parameter again. There was a problem of not becoming.

  The present invention has been made to solve the above-described problem, and an object of the present invention is to provide an optical disk playback apparatus with a hard disk capable of storing playback parameters during playback as playback parameter history in units of optical disks. Playing back an optical disk mounted on a hard disk, characterized in that playback using the stored playback parameter history is possible only when required by the user and that a large amount of playback parameter history can be recorded The object is to provide an apparatus (external medium reproducing apparatus equipped with a magnetic recording medium).

It is characterized by.

According to this configuration
The hard disk-mounted optical disk playback device of the present invention presets playback parameters (parameters for setting subtitles, audio, etc.) used when performing playback processing of video information recorded on an optical disk (external medium). It is possible. When the control unit receives an instruction to interrupt the reproduction process, it stores the resume point (reproduction interruption position) and the reproduction parameter in the hard disk (magnetic recording medium) and acquires identification information for uniquely identifying the optical disk. To do. The acquired identification information is stored in the hard disk in association with the resume point and the reproduction parameter. When a playback instruction is issued again for the optical disc for which playback has been interrupted, the control unit specifies the optical disc using the identification information, and the resume point and playback parameters associated with the optical disc are stored on the hard disc. Read out and use them to resume the playback process.

In order to achieve the above object, the hard disk-mounted optical disk playback device of the present invention is
When the reproduction process of the video information using the reproduction unit is completed, the reproduction parameter associated with the identification information of the external medium that has been performing the reproduction process is erased from the magnetic recording medium. Yes.

According to this configuration
When the reproduction of the optical disc is completed (for example, when the reproduction is performed to the end of the content and the reproduction is automatically stopped), the reproduction parameters set for the reproduced optical disc are deleted from the hard disk.

In order to achieve the above object, the hard disk-mounted optical disk playback device of the present invention is
In the playback parameter setting means, when the set playback parameter matches the initial value of the playback parameter, the playback parameter associated with the identification information of the external medium is erased from the magnetic recording medium. It is characterized by that.

According to this configuration
When the value of the playback parameter set for playback of the optical disc matches the initial value (for example, the set value at the time of shipment from the factory), the optical disk playback parameter is not recorded on the hard disk. If the value after the change matches the initial value, the reproduction parameter before the change remains stored in the hard disk, so that the reproduction parameter is deleted.

In order to achieve the above object, the hard disk-mounted optical disk playback device of the present invention is
When resuming the reproduction process of the external medium using the reproduction resuming unit, when the reproduction parameter associated with the identification information of the external medium is not stored in the magnetic recording medium, The reproduction process of the external medium is performed using the initial value.

According to this configuration
When the optical disk reproduction restart process is performed and the reproduction parameter for the optical disk is not recorded on the hard disk, the reproduction process is performed using the initial value of the reproduction parameter.

  According to the first configuration of the present invention, when a playback instruction is issued again for an optical disc for which playback has been interrupted, the control unit specifies the optical disc using the identification information and is associated with the optical disc. Resume points and playback parameters are read from the hard disk, and playback processing is resumed using them. For this reason, when the user resumes playback, the user can view with the same settings (subtitles, audio, etc.) as the previous re-occurrence, so there is no need to set again and the convenience of the user is improved. In addition, since a hard disk is used as a storage medium, it is possible to store more playback parameters than when a memory (ROM) or the like is used, for example. The previous playback parameter is used only when playback is resumed by the resume function. For example, when normal playback (playback from the beginning of the optical disk) is performed, the previous playback parameter is not used. For example, the reproduction is performed with the initial value or the like. For this reason, for example, when a plurality of users view a single optical disk in parallel, it is possible to avoid a problem that the reproduction is performed with the reproduction parameters set by other users.

  According to the second configuration of the present invention, when the reproduction of the optical disk is completed, the reproduction parameters set for the reproduced optical disk are erased from the hard disk. As a result, playback parameters that are no longer needed are deleted, and the capacity of the hard disk can be used more effectively.

  According to the third configuration of the present invention, when the value of the playback parameter set for playback of the optical disc matches the initial value, the playback parameter of the optical disk is not recorded on the hard disk. Further, when the reproduction parameter before the setting change remains stored in the hard disk, the reproduction parameter is deleted. As a result, it is possible to eliminate the waste of capacity consumption such as storing the setting parameter that matches the initial value in the hard disk.

According to the fourth configuration of the present invention,
When the optical disk reproduction restart process is performed and the reproduction parameter for the optical disk is not recorded on the hard disk, the reproduction process is performed using the initial value of the reproduction parameter. For this reason, an error does not occur even if reading of reproduction parameters fails when reproduction is resumed, and the user does not need to perform an operation to initialize the reproduction parameters.

  An embodiment of the present invention will be described below with reference to the drawings.

[Embodiment]
<1. Internal structure of HDD-equipped DVD player>
Here, the main configuration of the electric circuit system of the HDD-equipped DVD player 1 according to the first embodiment of the present invention will be described with reference to the block diagram of FIG.

  As shown in the block diagram of FIG. 3, the HDD-equipped DVD player 1 of the present invention includes at least a control unit 11, a memory 12, an HDD 13, a data input unit 14, an encoder unit 15, a decoder unit 16, a data output unit 17, and a control. The program storage unit 18, operation button group 21, front panel 22, and DVD slot 23 are included.

  The control unit 11 is a central processing unit for performing overall control of video information processing (content recording or playback, etc.) by organically controlling the drive of each member of the HDD-equipped DVD player 1. The control unit 11 is a central part that controls each device (for example, the HDD 13), calculates data, processes, and the like.

  The memory 12 is a medium for temporarily storing various data held by the HDD-equipped DVD player 1, and is composed of, for example, a writable RAM (Random Access Memory). The memory 12 serves as a buffer memory for temporarily storing, for example, processing data when various types of information processing are performed by the control unit 11 and instruction commands received from the user.

  The HDD 13 is a magnetic storage medium for recording various data (video data, audio data, management data, etc.) held by the HDD-equipped DVD player 1. The HDD 13 is physically divided into a plurality of areas (partitions), and it is more desirable to store the areas according to the type of data to be stored (video data, management data, etc.). The HDD 13 is configured to include, for example, a video information storage area 13a, a resume information storage area 13b, and a reproduction parameter storage area 13c. The video information storage area 13a is an area for storing actual video data (original data) recorded. The resume information storage area 13b is an area for storing the next playback start position (resume point) when playback is interrupted and the identification information of the DVD medium 91 that has stopped playback. The reproduction parameter storage area 13 c is an area for storing the reproduction parameters used by the user when reproducing the DVD medium 91 for each DVD medium 91.

  The data input unit 14 is an input interface for inputting digital data (video information) from an external device such as a digital tuner. For example, when analog data is input, analog video data and audio data can be converted into digital data and input using an A / D (Analog Digital) converter (not shown).

  The encoder unit 15 is a processing circuit for compressing (encoding) video data using a moving image compression method such as MPEG2, and compressing audio data using a sound compression method such as Dolby AC-3 or LPCM. Note that the data to be compressed is, for example, video data and audio data input from the data input unit 14.

  The decoder unit 16 is a processing circuit for decompressing (decoding) the video data and the audio data compressed by the encoder unit 15 and the like. The decompressed data is output to an external device using, for example, a data output unit 17 described later.

  The data output unit 17 is an output interface for outputting video data and audio data to an external device such as a monitor. For example, when the output destination device has only an analog interface, digital video data and audio data can be converted into analog data and output using a D / A converter.

  The control program storage unit 18 is a medium for storing program data for performing various processes (for example, video data input / output control, etc.) using the control unit 11, for example, a ROM that can only read information (Read Only Memory) or the like is used.

  The operation button group 21 is an input interface for the user to perform various instructions such as program recording and reproduction to the HDD-equipped DVD player 1. The front panel 22 is a user interface for displaying various information of the HDD-equipped DVD player 1 to the user.

  The DVD slot 23 is an optical device that stores the DVD medium 91 and optically reads or writes various data with respect to the DVD medium 91. Since there are a plurality of standards for DVD, various processes (recording, reproduction, etc.) cannot be performed without using the DVD medium 91 corresponding to the standard of the DVD slot 23.

<2. Reproduction process using reproduction parameters>
Here, the reproduction processing process using the reproduction parameters in the HDD-equipped DVD player 1 of the present invention will be described with reference to the flowchart of FIG. 1 and the block diagram of FIG.

  As shown in FIG. 1, when the control unit 11 detects the insertion of the DVD medium 91 into the DVD slot 23, this process is started (S110). Note that the DVD medium 91 is inserted, for example, when the user opens / closes the DVD slot 23 using the operation button group 21.

  The control unit 11 that has detected the insertion of the DVD medium 91 acquires identification information (information for uniquely identifying the type of the DVD medium 91) from the DVD medium 91 (S120). The control unit 11 that has acquired the identification information checks whether there is matching identification information in the resume information storage area 13b of the HDD 13 (S130).

  In the process of S130, when it is determined that there is no identification information matching the resume information storage area 13b, the content (video information) recorded on the DVD medium 91 is reproduced using a normal reproduction processing method. This process is terminated. Note that the content of the normal reproduction processing method is the same as that of the prior art, and the description thereof is omitted here.

  Conversely, when it is determined in the process of S130 that there is identification information that matches the resume information storage area 13b, the resume point of the DVD medium 91 uniquely identified by the identification information is stored in the resume information storage area 13b. It is confirmed whether it is stored (S140). The resume point is created when the DVD media 91 was previously inserted in the HDD-equipped DVD player 1 and the playback interruption process was performed during the playback of the content. Resume points are created in units of DVD media 91 and are individually stored in the resume information storage area 13b.

  In the process of S140, when it is determined that there is no resume point corresponding to the DVD medium 91 in the resume information storage area 13b, the content recorded on the DVD medium 91 is reproduced using a normal reproduction processing method. Therefore, this process ends. Note that the content of the normal reproduction processing method is the same as that of the prior art, and the description thereof is omitted here.

  Conversely, when it is determined in the processing of S140 that the resume information storage area 13b has a resume point corresponding to the DVD medium 91, the playback parameter corresponding to the DVD medium 91 is read from the playback parameter storage area 13c and read. Based on the reproduction parameters, the content stored in the DVD medium 91 is reproduced and output using the decoder unit 16 and the data output unit 17 (S150). If the playback parameters corresponding to the DVD medium 91 are not stored, the content is played back using the initial parameters of the playback parameters.

  During the process of S150, the control unit 11 monitors whether or not an instruction to interrupt the reproduction process is received until the reproduction ends (S160 and S180). Note that the reproduction processing interruption instruction is issued, for example, when the user presses a reproduction stop button included in the operation button group 21.

  In the process of S160, when the control unit 11 detects the reproduction interruption instruction, the control unit 11 instructs the decoder unit 16 and the data output unit 17 to stop the reproduction of the content, and when the reproduction interruption instruction is received. The reproduction position (resume point) is stored in the resume information storage area 13b of the HDD 13, and this process is terminated (S170). When storing the resume point, identification information is also stored in order to identify which DVD medium 91 the resume point is for.

  Conversely, when the control unit 11 does not detect the playback interruption instruction in the process of S160 and it is determined that the playback of the content is completed in the process of S180 (for example, automatically when the content is played back to the end). The control unit 11 erases the resume point of the DVD medium 91 stored in the resume information storage area 13b and the playback parameter of the DVD medium 91 stored in the playback parameter storage area. This process is terminated (S190).

<3. About parameter storage process for playback>
Here, the storage parameter storing process in the HDD-equipped DVD player 1 of the present invention will be described with reference to the flowchart of FIG. 2 and the block diagram of FIG.

  As shown in FIG. 2, when the control unit 11 detects an instruction to change the playback parameter from the user, this process is started (S210). The reproduction parameter change instruction is issued, for example, when the user uses the operation button group 21 to change various settings (subtitles, audio, etc.) during content reproduction.

  The control unit 11 that has detected the reproduction parameter change instruction acquires identification information from the DVD medium 91 (S220). The control unit 11 that has acquired the identification information confirms the changed content of the playback parameter received from the user in S210, and whether the changed playback parameter is the same as the initial parameter (for example, the value at the time of factory shipment). A determination is made (S230).

  In the process of S230, when it is determined that the changed playback parameter is the same as the initial parameter, the control unit 11 plays back the HDD 13 based on the identification information of the DVD medium 91 obtained in S220. The reproduction parameter corresponding to the DVD medium 91 stored in the parameter storage area 13c is deleted (S240). As a result, there is no playback parameter for the DVD medium 91, so when the DVD medium 91 is played next time, playback using the initial parameters is performed.

  Conversely, if it is determined in the process of S230 that the changed playback parameter is different from the initial parameter, the control unit 11 plays back the HDD 13 based on the identification information of the DVD medium 91 obtained in S220. The reproduction parameter corresponding to the DVD medium 91 is stored in the parameter storage area 13c (S250). As a result, when the DVD medium 91 is reproduced next time, reproduction using the reproduction parameters stored for each DVD medium 91 in the reproduction parameter storage area 13c is performed. The details of this process are described in <2. Since the content is the same as that of the reproduction processing step using the reproduction parameter, the description thereof is omitted here.
