Description

  The present invention relates to a content recording apparatus that records content recorded on an external recording medium and acquires and records content information related to the content from an external server.

  The music data read from the CD is recorded on a PC (personal computer), and the music data recorded on the PC is played back, or the data is read from the CD to an HDD recorder which is an audio device equipped with an HDD (Hard Disk Drive). The music data recorded is recorded and the music data recorded on the HDD is reproduced. When recording CD music data on these devices, by accessing an external content information (eg, CDDB) server via the Internet and transmitting the TOC (Table Of Contents) information of the CD to the content information server, Content information (for example, song name, artist name, album name, etc.) relating to each piece of music data of the CD is acquired from the content information server. The acquired content information is recorded in the ID3 tag of the MP3 file, or is recorded in association with each piece of music data in the content information database recorded in the HDD. When the user selects desired song data from a plurality of song data, a song list which is a list of content information of song data is displayed on the display unit.

  Here, in order to access the content information server and acquire the content information of the song data of the CD, the HDD recorder needs to be connected to the CDDB via the Internet. However, when recording the song data of the CD on the HDD, if the HDD recorder cannot connect to the Internet for some reason and cannot access the content information server, the content information cannot be acquired and the song data is recorded on the HDD. Will be completed. Since the content information cannot be obtained from the content information server later for the song data recorded in the HDD, the user needs to input the content information for each song data.

  Similarly, when the CD song data is recorded on the HDD, the content information server can be accessed via the Internet, but the content information related to the TOC information of the CD is not yet registered in the content information server. Information cannot be obtained. Even if the content information related to the TOC information is registered in the content information server later, the content information cannot be acquired later for the song data recorded in the HDD.

  The following Patent Document 1 describes the following contents. In other words, the content information cannot be acquired from the content information server because the corresponding TOC information does not exist for the user's own CD in which other music is added to the music data of the CD whose content information is registered in the content information server. In this case, a technique is described in which TOC information including only information on predetermined song data is newly generated from the TOC information of a self-made CD, and the content information is acquired again by accessing the content information server.

  According to this technology, content information can be acquired from a content information server even for a user's own CD, but when the CD is recorded on the HDD, it is not possible to connect to the content information server via the Internet, or the content information is still Is not registered in the content information server, the content information relating to the song data of the CD cannot be acquired.

  The present invention has been made in order to solve the above-described conventional problems. The purpose of the present invention is when content information cannot be acquired for some reason when content recorded on an external recording medium is recorded on the recording medium. However, it is to provide a content recording apparatus that can later acquire content information related to the content.

  A content recording apparatus according to a preferred embodiment of the present invention includes one or a plurality of contents, content information related to the contents, a storage unit for recording the table of contents information, and a reading unit that reads the contents and the table of contents information from an external recording medium. Content recording means for recording the content read by the reading means in the storage unit, and acquisition means for acquiring content information about the content from an external server based on the table of contents information read by the reading means Content information recording means for recording the content information acquired by the acquisition means in association with the content in the storage unit, and when the content is recorded in the storage unit by the content recording unit, the acquisition unit Determining means for determining whether or not the content information has been acquired by A table of contents recording means for recording the table of contents information in the storage unit and recording the correspondence between the contents and the table of contents information in the storage unit when it is determined that the content information could not be acquired by the means; A second determination unit that determines whether or not the table of contents information is recorded in the storage unit, and when the second determination unit determines that the table of contents information is recorded in the storage unit, An acquisition unit acquires content information related to the content from the external server based on the table of contents information recorded in the storage unit, and the content information recording unit determines whether the content and the table of contents information correspond to each other. The content information is recorded in association with the content.

  When recording the content of the external recording medium in the storage unit, if the content information cannot be acquired from the external server for some reason, the table of contents information is recorded in the storage unit, and the correspondence between the table of contents information and the content is stored in the storage unit. To record. For example, it is periodically determined whether or not the table of contents information is recorded in the storage unit. When the table of contents information is recorded, the content information is tried again using the table of contents information. When the content information can be acquired, the correspondence between the table of contents information and the content is referred to, the content to be recorded with the content information is specified, and the content information is recorded in association with the content. Accordingly, when recording the content of the external recording medium in the storage unit, even if the content information cannot be acquired from the external server for some reason, the content information can be recorded in association with the content later.

  In a preferred embodiment, the table of contents recording means records a correspondence relationship between the content, the table of contents information, and a track number of the content on the external recording medium in the storage unit, and the second judging means records the correspondence. When it is determined that the table of contents information is recorded in the storage unit, the acquisition unit acquires content information about the content from the external server based on the table of contents information recorded in the storage unit, and The content information recording means records the content information in association with the content according to the correspondence relationship between the content, the table of contents information, and the track number.

  When the table of contents information is recorded in the storage unit, in addition to the table of contents information and the content, the correspondence relationship with the track number is also recorded. Therefore, after the content is recorded in the storage unit, a certain content among the contents of a plurality of tracks Even if the content information is deleted or moved to another folder, it is possible to accurately specify the content to be recorded with the content information acquired later.

  In a preferred embodiment, the table of contents recording means assigns table of contents identification information to the table of contents information recorded in the storage unit, and the content identification information includes the table of contents identification information and the track number in a tag of the content Is recorded in the storage unit, and the second determination unit determines that the table of contents information is recorded in the storage unit. The acquisition unit acquires content information related to the content from the external server based on the table of contents information recorded in the storage unit, and the content information recording unit stores the content information recorded in a tag. When the table of contents identification information included in the content identification information matches the table of contents identification information of the table of contents information from which the content information was acquired, The content information identified by the rack number is recorded.

  In this case, since the correspondence between the content, the table of contents information, and the track number is recorded as content identification information in the tag of the content, it is not necessary to separately manage the correspondence using a table or the like.

  In a preferred embodiment, the content information recording unit can record the content information in the storage unit by character input by a user operation, and the table of contents information is recorded in the storage unit by the second determination unit. When the acquisition unit acquires content information related to the content from the external server based on the table of contents information recorded in the storage unit, the acquired content information is recorded as content to be recorded. On the other hand, third determination means for determining whether or not the content information has already been recorded by character input of a user operation, and when the content information has been recorded by the third determination means, the recorded content information Whether or not the acquired content information should be overwritten based on the user operation or the setting state by the user operation A fourth determination unit, and when the fourth determination unit determines that the content information should be overwritten, the content information recording unit overwrites the recorded content information with the acquired content information. When it is determined by the determination means that it should not be overwritten, the content information recording means retains the recorded content information as it is.

  In this case, it is possible to prevent the content information recorded by the character input of the user operation from being overwritten by the content information acquired based on the table of contents information regardless of the user's intention.

  In another aspect of the present invention, a content recording program and a content recording method relating to the content recording apparatus can be provided.

  According to the present invention, when recording the content of the external recording medium in the storage unit, even if the content information cannot be acquired from the external server for some reason, the content information can be recorded in association with the content later. it can.

  FIG. 1 is a block diagram showing a content recording apparatus (for example, PC, HDD recorder, etc.) 100 according to a preferred embodiment of the present invention. The content recording apparatus 100 can be connected to an external content information server (for example, a CDDB server) 200 via an arbitrary network such as the Internet, and transmits the TOC information (table of contents information) of the CD to the content information server 200. Content information can be acquired in units of CD song data. “Content” is a general term for video data, music (music) data, still image data, and the like, and in this example is music data. “Content information” refers to metadata and attribute information, such as song name, artist name, album name, genre name, release year, and the like.

  The outline will be described. The content recording apparatus 100 transmits the TOC information of the CD to the content information server 200 when recording the song data recorded on the CD in the HDD 13, and the content related to the song data of the CD from the content information server 200. Get information. At this time, if it is not possible to connect to the content information server due to a network failure, the TOC information of the CD is temporarily recorded in the HDD 13, and the content information server 200 is accessed again after a predetermined time has elapsed. The content information is acquired from the content information server 200. Note that the TOC (Table of contents) is table-of-contents information of a CD on which information such as a CD track and a session is written.

  The content recording apparatus 100 includes a control unit 11 such as a microcomputer, a memory 12, a storage unit 13 such as a hard disk drive (HDD), a communication unit 14, an optical disk drive 15, a reproduction processing unit 16, and a display unit 18. And an operation unit 19, which are connected to each other by a bus or the like. The content recording apparatus 100 may further include a speaker (not shown) connected to the reproduction processing unit 16 as necessary. The communication unit 14 can be connected to the Internet via, for example, a LAN cable, and can be connected to the external content information server 200 via the Internet.

  When an external recording medium such as a CD is inserted, the optical disk drive 15 reads a plurality of music data in the inserted CD. The optical disk drive 15 reads the TOC information of the inserted CD.

  The HDD 13 records a plurality of music data read by the optical disk drive 15 in the format set by the control unit 11. For example, in this example, the music data is recorded in the HDD 13 in the MP3 format, but is not limited to this, and may be recorded in AAC, Atrac3, PCM, or the like.

  The MP3 file of song data has an ID3 tag, and content information related to song data can be registered in the ID3 tag. FIG. 2 shows an example of the data structure of the ID3 tag. The ID3 tag includes a song title Title, an artist name Artist, an album name Album, a release year Year, a genre name Genre, and a song identification number SongIN. In each field of the ID3 tag, each information acquired from the content information database 200 is recorded, or each information is recorded by a character input by a user operation.

  The music identification number is generated by combining the TOC identification number (described later in detail) given to the TOC information of the CD in which the music data is recorded and the track number. That is, the music identification number indicates a correspondence relationship between the music data, the TOC information, and the track number. For example, if the TOC identification number is 0001 and the track number is 3, the music identification number is represented as 0001003, and if the TOC identification number is 0003 and the track number is 11, the music identification number is represented as 0000311. . In detail, an identifier (for example, AAA etc.) indicating the music identification number is attached to the head of the music identification number, which is expressed as AAA0001003, etc., but in this example, the head is given to simplify the explanation. The description will be omitted.

  If the song data recorded in the HDD 13 has a format that does not have an ID3 tag, the content information database (song table) recorded in the HDD 13 is used instead of managing the content information with the ID3 tag. Each piece of content information may be managed.

  Also, if the HDD 13 cannot acquire the content information of the CD song data because it cannot connect to the content information server 200 when recording the CD song data, the HDD 13 stores the TOC information of the CD as a TOC information file. . The TOC information stored in the HDD 13 is given a unique TOC identification number (for example, 0001, 0002, etc.) that does not match other TOC information currently stored in the HDD 13 by the control unit 11. For example, as shown in the TOC information file list in FIG. 3, five TOC information files having TOC identification numbers 0001 to 0005 are recorded in the HDD 13. In this case, when the next other TOC information file is recorded on the HDD 13, the TOC identification number 0006 is given. The file name of the TOC information file includes the TOC identification information. For example, if the TOC identification number is 0001, the first character “TOC” is added and the file name becomes TOC0001 or the like.

  The fact that the TOC information file is recorded in the HDD 13 means that the content information of the music data of the CD specified by the TOC information has not been acquired. When the TOC information file is acquired, the TOC information file is erased from the HDD 13, and the TOC identification number assigned to the TOC information file becomes an empty number, so that the TOC identification number can be newly assigned to another TOC information file. .

  The control unit 11 controls the entire content recording apparatus 100 based on the operation program of the content recording apparatus stored in the memory 12 or the HDD 13. For example, when the CD is inserted, the control unit 11 transmits the TOC information of the CD to the content information server 200 and determines whether or not the content information has been acquired. If the content information cannot be acquired, the TOC information of the CD is stored in the HDD 13 as a TOC information file, and a TOC identification number is assigned to the TOC information file to determine the file name of the TOC information file. Then, the control unit 11 records the music data of the CD on the HDD 13 and manages the TOC identification number and the track number of the TOC information in association with the music data. That is, the control unit 11 generates and records a music identification number including a TOC identification number and a track number instead of recording content information such as a music title in the ID3 tag of the music data.

  Further, the control unit 11 periodically determines whether or not a TOC information file is recorded in the HDD 13. If the TOC information file is recorded, the control unit 11 reads the TOC information file and transmits the TOC information to the content information server. Try to get it again. If the content information can be acquired, the acquired content information is referred to by referring to the music identification information of the music data recorded in the HDD 13, that is, referring to the correspondence between the music data, the TOC identification information, and the track number. The music data to be recorded is specified, and the acquired content information is recorded in the ID3 tag of the music data.

  Note that the music identification number may include only the TOC identification number, but by including the track number, a part of the music data of a plurality of music data of a certain CD is deleted from the HDD 13. Or, even if it is moved, the song data can be accurately associated with the acquired content information.

  The memory 12 includes a read only memory (ROM) and a random access memory (RAM). The content information acquired from the content information server 200 is temporarily stored in the memory 12, and after the song data is recorded in the HDD 13, the content information stored in the memory 12 is written in the ID3 tag.

  The display unit 18 displays a list of music data content information recorded in the HDD 13 and content information of the music data of the inserted CD, and is an LCD (liquid crystal display), FL tube, or the like. Alternatively, when a display device connected to the outside is used, the display unit 18 employs an OSD processing unit that performs OSD display on the external display.

  The reproduction processing unit 16 performs reproduction processing, decoding processing, digital-analog conversion, and / or amplification processing on the music data selected by the microcomputer 11. A speaker (not shown) receives the audio signal output from the reproduction processing unit 16 and outputs it to the outside as audio. The operation unit 19 receives a user operation and is an operation button, a remote controller, or the like.

  Hereinafter, the operation of the control unit 11 of the content recording apparatus 100 of the present invention will be described with reference to FIGS. First, referring to FIG. 4, when a CD is inserted into the optical disc drive 15, the control unit 11 reads the TOC information from the CD and temporarily stores it in the memory 12 (S11). Next, the control unit 11 inquires of the content information server 200 about content information based on the TOC information (S12). That is, the control unit 11 transmits the TOC information to the content information server 200, and the content information server 200 reads out the content information corresponding to the TOC information from its own database and returns it to the content recording device 100.

  The control unit 11 determines whether content information has been acquired from the content information server 200 (S13). For example, it is confirmed whether or not the content information is returned within a predetermined time after transmitting the TOC information. If the content information can be acquired (YES in S13), the entire music data of the CD is recorded in the HDD 13 in S20 to S22, and the acquired content information is recorded in the ID3 tag of the music data.

  On the other hand, for example, when the content information for the TOC information is not registered in the content information server 200 or the content information cannot be acquired because the network information cannot be connected to the content information server 200 (NO in S13). In S14 to S19, the control unit 11 stores the TOC information file, records the song data, and records the song identification number in the ID3 tag of the song data.

  Specifically, a TOC identification number assigned to the TOC information file when the TOC information file is next recorded in the HDD 13 is set in the memory 12. Therefore, the control unit 11 gives the TOC identification number to the TOC information. Then, the control unit 11 combines the assigned TOC identification number after the character string “TOC” to generate the file name of the TOC information file (S14). For example, if the assigned TOC identification number is 0001, TOC0001 is generated as the file name. Thereafter, the control unit 11 records the TOC information on the HDD 13 as a TOC information file having the file name (S15).

  Subsequently, in S16 to S18, the control unit 11 reads the music data from the CD, records it on the HDD 13, and records the music identification number on the ID3 tag of the MP3 file. More specifically, the control unit 11 first reads out the music data at the beginning of the CD (music data with track number 1) and records it in the HDD 13 (S16). Next, the control part 11 produces | generates a music identification number from the TOC identification number provided by S14, and a track number about the recorded music data, and records it on ID3 tag of the recorded music data (S17). In this case, 0001001 is generated as the music identification number and recorded in the ID3 tag. The control unit 11 determines whether or not all the song data of the CD has been recorded in the HDD 13 (S18). If all the song data has not yet been recorded (NO in S18), the control unit 11 returns to S16 and the next song data is the same. Record in the same way. When all the music data has been recorded (YES in S18), the control unit 11 increments the TOC identification number stored in the memory in order to record the TOC information of another CD in the HDD 13 next time. Set to 0002 (S19)

  When the CD song data is recorded in the HDD 13 by the above processing, if the content information of the CD song data cannot be acquired, the TOC information of the CD is recorded in the HDD 13, and the process described below. The content information can be acquired later.

  Next, when the control unit 11 can acquire content information from the content information server 200 by periodically executing the process of FIG. 5 on the TOC information file recorded in the HDD 13. The content information of the song data in which the TOC information file is recorded in the HDD 13 is acquired from the content information server 200.

  First, the control unit 11 determines whether or not a TOC information file is recorded in the HDD 13 (S31). If no TOC information file is recorded (NO in S31), the content information acquired from the content information server 20 is recorded in all the song data recorded in the HDD 13, and the process is terminated.

  When the TOC information file is recorded in the HDD 13 (YES in S31), the control unit 11 selects any one TOC information file and acquires the TOC information from the TOC information file (S32). Then, the control part 11 transmits TOC information to the content information server 200, and acquires content information from the content information server 200 (S33). And the control part 11 judges whether the content information with respect to the said TOC information was able to be acquired from the content information server 20 (S34). If the content information cannot be acquired (NO in S34), the process ends.

  For example, when the content information for the TOC information is registered in the content information server 200 or the content information can be acquired due to a network failure recovery (YES in S34), the control unit 11 performs S35 to S39. The music data to be recorded with the content information is retrieved from the HDD 13 and the content information is recorded. Specifically, the control unit 11 selects one piece of music data recorded on the HDD 13 and reads each piece of information recorded on the ID3 tag (S35). The control unit 11 determines whether or not the music identification number is included in each piece of information of the read ID3 tag (S36). That is, it is determined whether or not the content information acquired from the content information server 200 is song data that is not recorded. If the music identification number is not recorded (NO in S36), the process proceeds to S39. If all the music data in the HDD 13 has not been processed (NO in S39), the process returns to S35 and the process proceeds to the next music data.

  When the music identification number is recorded (YES in S36), the control unit 11 determines whether or not the TOC identification number included in the music identification number matches the TOC identification number of the TOC information file from which the content information can be acquired this time. Is determined (S37). That is, it is determined whether or not the music data is specified by the TOC information from which the content information can be acquired (content information should be recorded). If they do not match (NO in S37), it is not necessary to record the content information acquired this time in this song data, and the process proceeds to S39.

  On the other hand, if they match (YES in S37), the control unit 11 extracts the track number included in the music identification number and corresponds to this track number in the content information for a plurality of tracks acquired from the content information server 200. Content information is extracted and recorded in the ID3 tag of the song data (S38). As described above, since the track number is managed in addition to the TOC identification number for the music data in which the content information is not recorded, it is easy to specify which content information of the acquired content information should be recorded. Can do.

  Thereafter, the process proceeds to S39, in which the control unit 11 determines whether or not the processing has been completed for all song data in the HDD 13 (S39). If all the music data has not been completed yet (NO in S39), the process returns to S35, and the processes of S35 to 38 are executed for the next music data in the HDD 13. If the processing is completed for all music data (YES in S39), the TOC information file is deleted from the HDD 13 (S40). As a result, it is possible to prevent the process of FIG. 5 from being erroneously executed again for the TOC information in which the content information has already been acquired from the content information server 200 and the content information has been recorded in the song data. Thereafter, the process returns to S31, and the same processing is executed for the other TOC information files recorded in the HDD 13.

  When the TOC information file is recorded in the HDD 13 by the above processing, the acquisition of content information is periodically tried using the TOC information. Therefore, when an environment in which content information can be acquired using TOC information is prepared, the content information can be acquired from the content information server 200 and recorded in the song data.

  Next, another embodiment of the present invention will be described with reference to the flowchart of FIG. FIG. 6 differs from FIG. 5 in that S51 to S53 are added, and the others are the same. As described above, when the content information cannot be acquired when the CD song data is recorded in the HDD 13, the CD TOC information file is stored in the HDD 13. In this example, before the content information is acquired from the TOC information by the regular process, the user inputs the content information of the song data via the operation unit 19 to record the content information in the ID3 tag. it can.

  When the content information is acquired based on the TOC information file, and the TOC identification number of the music identification number matches the TOC identification number of the TOC information from which the content information is acquired (YES in S37), the control unit 11 performs a character operation by the user operation. It is determined whether the content information has been registered by the input (S51). If the content information has been registered by character input by a user operation (YES in S51), an inquiry screen is displayed on the display unit 18, for example, to indicate whether the acquired content information may overwrite the content information recorded in the ID3 tag. In this way, the user is inquired (S52). For example, on the inquiry screen, the content information recorded by the character input of the user operation and the content information acquired from the content information server 200 based on the TOC information file are displayed, and “Do you want to change the content information?” Should be displayed. When an overwrite instruction is input by a user operation (YES in S53), the acquired content information is recorded in the ID3 tag as described above (S38).

  On the other hand, when an instruction not to overwrite is input by a user operation (NO in S53), the process proceeds to S39 without overwriting with the content information acquired based on the TOC information file. That is, the content information input by the user operation is recorded in the ID3 tag as it is. If no content information is input to the ID3 tag by a user operation in S51 (NO in S51), the process proceeds to S38 and the content information is recorded in the ID3 tag.

  As described above, in this example, it is possible to prevent content information recorded in song data by a user operation from being erased by content information acquired based on TOC information regardless of the user's intention. .

  In addition, for each piece of music data, it is very annoying to inquire whether the recorded content information may be overwritten by inputting characters into the ID3 tag with the acquired content information. It may be displayed.

  In addition, by using a flag of the memory 12 or the like, it is set in advance whether or not to overwrite the recorded content information by character input with the content information acquired based on the TOC information by a user operation (in this case, all songs It is also possible to make a determination in S53 by checking the flag of the memory 12 without executing the inquiry process in S52.

  In addition, when inputting the content information in the ID3 tag by a user operation, whether or not to overwrite the content information of the song data with the content information acquired based on the TOC information is set for each song data. May be.

  As mentioned above, although preferable embodiment of this invention was described, this invention is not limited to these embodiment. For example, the same applies when content information is recorded in a content information database or the like in the HDD 13 instead of recording content information in the ID3 tag. Even if the music identification number does not include the track number, the same processing can be performed when the music data recorded in the HDD 13 is recorded in the same folder in the order of the tracks. However, by including the track number in the music identification number, it is possible to correctly associate the music data and the content information when a part of the music data is deleted or moved to another folder. Further, the TOC identification number and the music identification number may be characters instead of numbers. The present invention may be provided in the form of a computer program for operating the content recording apparatus 100 described above or a recording medium on which the computer program is recorded.

  The present invention can be suitably applied to audio devices such as PCs and HDD recorders.
