Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is an explanatory diagram of the principle configuration of the recording apparatus of the present invention.
The recording apparatus 1 shown in FIG. 1 is an apparatus capable of recording related information related to content provided via a network 30.

  The recording apparatus 1 includes a temporary storage unit 2 that temporarily stores related information of a plurality of contents provided via the network 30, and a storage unit 3 that stores the related information stored in the temporary storage unit 2 as a set of a plurality of related information. Or instructing means 4 for instructing whether to record in the storage means 3 as one piece of related information. Furthermore, the recording apparatus 1 has a recording unit 5 that records the related information stored in the temporary storage unit 2 in the storage unit 3 in units of sets or in units in response to an instruction from the instruction unit 4.

  Further, the recording device 1 is instructed by the instruction unit 4 to record the related information of the set unit in the storage unit 3 and when the predetermined capacity in the storage unit 3 is insufficient, When a plurality of related information recorded in a set unit is erased, while one unit of related information is instructed to be recorded in the storage unit 3, and the predetermined capacity in the storage unit 3 is insufficient The erasing unit 6 erases one piece of related information recorded in the storage unit 3 in one unit.

  When recording related information in the recording apparatus 1 having the above configuration, the recorded related information is first temporarily stored in the temporary storage unit 2. At that time, the recording device 1 instructs the instruction unit 4 whether to record the related information temporarily stored in the storage unit 3 in units of sets or in units of one unit. Then, in response to the instruction, the recording device 1 records the related information in the storage unit 3 by the recording unit 5 in units of sets or in units.

  For example, in the case of recording related information of music content, the recording apparatus 1 records related information for one song or collects related information for a plurality of songs composed of a plurality of songs. Whether to record is instructed by the instructing means 4, and accordingly, related information is recorded in the storage means 3 in units of one song or in units of a plurality of songs.

  When a plurality of pieces of related information in a set unit are newly recorded, if the capacity of the storage unit 3 to record them is insufficient, the recording device 1 has already stored the storage unit 3 in the set unit. Is deleted, and a plurality of related information in a new set unit is recorded.

  Further, when a new unit of related information is to be recorded, if the capacity in the storage unit 3 to record it is insufficient, the recording apparatus 1 has already stored the storage unit 3 in one unit. The recorded related information is deleted, and a new unit of related information is recorded.

  Thus, for example, in the case of the related information of the above-described music, if the capacity is insufficient when newly recording related information for one music, the conventional one and multiple music are recorded. The existing related information is erased in the old order regardless of whether the existing related information for one song is erased, and the new related information for one song is recorded. Become. Therefore, since the related information for one song is recorded, the related information for a plurality of songs is not deleted without permission.

  In such a recording apparatus 1, the storage unit 3 includes a dedicated area in which only related information in a set unit is recorded, a dedicated area in which only related information in one unit is recorded, and either a set unit or one unit. It is possible to provide a common area where related information is also recorded. When the recording device 1 detects whether or not the storage means 3 has a capacity shortage when recording the related information, the recording device 1 checks the capacity of the related information in the set unit and the capacity of the related information in one unit in the storage means 3 respectively. Furthermore, the capacity of the entire storage means 3 is checked. The recording device 1 records the related information of the set unit if there is an empty area (total of the dedicated area and the common area) in which the related information of the set unit can be recorded, and the area of the related information (dedicated) If there is a vacancy in the total area and common area), 1 unit of related information is recorded. If there is no space, the related information already recorded is deleted from the storage means 3 in units of sets or in units according to the above flow.

  When erasing the recorded related information, for example, in the case of newly recording related information of a set unit, the oldest recorded related information of the set unit is deleted, and 1 unit of related information is deleted. Is newly recorded, the oldest recorded unit of related information is deleted. In addition, the related information can be deleted in an appropriate order in consideration of the use frequency of the related information, the update date and time, and the like.

  Hereinafter, a system to which the above recording apparatus 1 is applied will be described. In the present embodiment, the recording device 1 is used as a terminal device connected to a server such as a broadcasting station via a network, and the user of the terminal device can acquire related information of music provided by the server via the network. A network system will be described as an example.

  Here, the related information of the music includes the name and number of the CD or the like on which the music is recorded, the release year, the release source, the date and time when the music was broadcast, in addition to the music title and artist name. Hereinafter, when the user acquires the related information of the music, the process of recording the related information is referred to as “clip”, and the clipped related information is referred to as “clip information”.

FIG. 2 is a diagram showing a network system according to the embodiment of the present invention.

The broadcast station server 32 is a server managed by a broadcast station such as FM broadcast or TV broadcast, and provides a service for providing related information of music to be broadcast. The function of providing related information by the broadcast station server 32 is roughly divided into the following two. The first function is a function (now-on-air) that provides related information of the music currently being broadcast. The second function is a function that provides a list of related information (on-air list) of already broadcasted music in response to a request from the terminal device 10. For example, the broadcast station server 32 provides related information of music broadcasted in a designated program, or provides related information of music broadcasted in a designated time zone.

  The music distribution server 33 is a server that provides a service for distributing digital music data (music data). For example, the music distribution server 33 provides music data only to the terminal device 10 of the user who performed the music purchase procedure. In addition, the music distribution server 33 can provide related information of the music to be distributed.

  The CD shop server 34 is a server that accepts orders for mail order sales of CDs. The CD shop server 34 also provides a distribution service for audio data for trial listening, and a service for providing related information of music recorded on a CD being sold.

  As described above, a plurality of servers provide a service for providing information related to a music piece or a set of music pieces on the network 30. That is, each server functions as a source of music or a set of music on the network 30.

  The server shown in FIG. 2 is an example of an apparatus that provides a source of music or a set of music via the network 30. In other words, any device that can access the source of a song or a set of songs on the network 30 from another device can function as the source of the song or the set of songs on the network 30.

  The music distribution server 33 and the CD shop server 34 are music purchaseable servers, and have a function of selling audio data of music and audio data of a set of music online. If the user operates the terminal device 10 to access the music purchase-available server, it is possible to actually purchase a music piece or a set of music pieces via the network 30. The user of the terminal device 10 can download audio data from the music distribution server 33 by performing a purchase procedure for the music distribution server 33. In addition, the user of the terminal device 10 can have the CD shop server 34 deliver a CD or the like to the home by performing a purchase procedure with respect to the CD shop server 34.

  The terminal device 10 holds a source of a local music piece or a set of music pieces on a recording medium such as a CD 19 a ′, an MD 19 b ′, and a hard disk drive (HDD) 21. These sources differ depending on the type and purpose of the terminal device 10.

  Note that the source of the local music or the set of music shown in FIG. 2 is an example. That is, if the recording medium exists locally in the terminal device 10, it can function as a source of a local music or a set of music by recording a music or a set of music.

  Further, the terminal device 10 includes a clip information storage device 21a for recording related information clipped. The clip information storage device 21 a is a secondary storage device of the terminal device 10. For example, a part of the storage area such as the HDD 21 can function as the clip information storage device 21a. The terminal device 10 can clip a music piece or a set of music pieces. As a result, FM programs, CD albums, etc. that contain a lot of songs that you are interested in can be clipped as a whole, and related information on the song group (music list) that you are interested in can be recorded in a single clip operation. Can do.

Here, a recording format of clip information in the terminal device 10 will be described.
FIG. 3 is an explanatory diagram of a clip information recording format.
In the terminal apparatus 10, the clip information 50 is classified into a clip information list 51 for each song or clip information 52, 53 for each set, depending on whether the clip information 50 is clipped in units of songs or in sets. And recorded in the clip information storage device 21a.

  In the clip information list 51 for each song, clip information 51a and 51b for the first and second clips are recorded in a list format in order for each clip. The new clip information 51c for each piece of music is recorded so as to form a list 51 of clip information for each piece of music together with the other clip information 51a and 51b.

  Each piece of clip information 52, 53, which is related to the music group, stores information related to the music group obtained by one clip operation in a list format. For example, as shown in FIG. 3, it is recorded independently from the clip information 52, 53 of other set units.

By adopting such a recording format, clip information for each song and clip information for a set can be handled in the same manner.
Note that the number of clip information lists in one song unit shown in FIG. 3, the number of clip information included in the list, the number of clip information in a set unit, and the number of clip information included in the list are merely examples. The number of each is not limited to the example of FIG.

FIG. 4 is an explanatory diagram of a clip information recording area.
The clip information storage device 21a includes a dedicated area 21b in which only related information in one song unit is recorded, a dedicated area 21c in which only related information in a set unit is recorded, and both related information in one song unit and a set unit. A common area 21d to be recorded is provided. The maximum value of the area in which the related information for one song unit is recorded is the sum of the dedicated area 21b and the common area 21d, and the maximum value of the area in which the related information for the set unit is recorded is the dedicated area 21c and the common area 21d. Total.

  When the recording device 1 detects whether or not the clip information storage device 21a has insufficient capacity, the clip information storage device 21a checks the capacity of the clip information in units of sets and the capacity of clip information in units of one song, respectively. The entire capacity of the clip information storage device 21a is checked. As a result, an empty area of the clip information storage device 21a is detected, and it is possible to detect whether or not new related information can be recorded in the empty area in units of one song or set.

  If there is an empty area in which the related information for each song can be recorded in the dedicated area 21b or the common area 21d, the related information for each song is recorded as a list of clip information for each song as shown in FIG. Is done. If there is a vacant area in which the related information of the set unit can be recorded in the dedicated area 21c or the common area 21d, the related information of the set unit is recorded as clip information of the set unit as shown in FIG.

  If there is no free area in which the related information of one song unit or set unit can be recorded, the relevant information of one song unit or set unit is clipped after the appropriate clip information is erased. It is recorded in the information storage device 21a.

  Note that the terminal device 10 may be configured such that the user can arbitrarily set the sizes of the dedicated areas 21b and 21c and the common area 21d. It is also possible not to set special sizes of the dedicated areas 21b and 21c and the common area 21d. Also in this case, when detecting whether or not the clip information storage device 21a has insufficient capacity, the capacity of clip information in units of sets, the capacity of clip information in units of one song, and the capacity of the entire clip information storage device 21a are checked. If there is a free area, new related information in units of one song or set is recorded.

By the way, the terminal device 10 according to the present embodiment also has a function as an audio device having a music reproduction function.
FIG. 5 is a diagram illustrating an appearance of the terminal device.

  As shown in FIG. 5, the terminal device 10 according to the present embodiment has the same appearance as a general system component. The terminal device 10 includes a device main body 10a, speakers 25a and 25b, and a remote controller 40. The apparatus main body 10a has a CD / DVD playback function, an MD recording / playback function, and an FM broadcast or TV broadcast reception function. The sound signal generated by the apparatus body 10a is sent to the speakers 25a and 25b, so that sound is output from the speakers 25a and 25b.

Further, a display device 17 is provided in the apparatus main body 10a. The display device 17 displays information related to the music being played, clip information, and the like.
The remote controller 40 is an input device for remotely operating the apparatus main body 10a. The remote controller 40 is provided with a plurality of operation keys. When the operation key is pressed by the user, a signal corresponding to the pressed operation key is transmitted from the remote controller 40 to the apparatus main body 10a by wireless communication means such as infrared rays.

The operation keys include direction keys 41a to 41d, an enter key 42, function selection keys 43a to 43c, a tool key 44, a return key 45, and the like.
The direction keys 41a to 41d are used, for example, to move a cursor displayed on the display device 17 or a place to be focused. The four direction keys 41a to 41d correspond to the up, down, left, and right directions, respectively, and the cursor or the like moves in the direction corresponding to the pressed direction key.

The decision key 42 is used, for example, to confirm the content displayed on the display device 17.
The function selection keys 43a to 43c are used for selecting a function. For example, the three function selection keys 43a to 43c are associated with an integrated service utilization function, a tuner function, and a local content management function, respectively. When any one of the function selection keys is pressed, the apparatus main body 10a enters the operation mode of the function corresponding to the pressed function selection key.

  The tool key 44 is a button for displaying a tool menu on the display device 17. A command corresponding to the content displayed on the display device 17 is displayed in the tool menu.

For example, when the user operates the direction keys 41a to 41d to select an arbitrary command and further presses the enter key 42, processing corresponding to the selected command is executed in the apparatus main body 10a. For example, the user of the terminal device 10 selects and decides a clip command with the tool key 44 and the direction keys 41a to 41d when the broadcasted music is displayed on the display device 17 as now-on-air information or an on-air list. If the key 42 is pressed, the music being displayed can be clipped.

The return key 45 is a button for returning the display content of the display device 17 to the previous state.
The remote controller 40 can be provided with various operation keys other than those shown in FIG. For example, a volume adjustment key, a reproduction key such as a CD, and a stop key.

Next, the internal configuration of the terminal device 10 will be described.
FIG. 6 is a block diagram illustrating a hardware configuration of the terminal device.
The terminal device 10 as shown in FIG. 6 can manage, record, and play various sources such as music.

  A CPU (Central Processing Unit) 11 performs overall control and arithmetic processing of the terminal device 10 based on the activated program. For example, a communication operation via the network 30, an input / output operation for the user, a content reproduction or clip from the media, a content storage in the HDD 21 or management for the content, an information search via the network 30 based on the clipped related information, etc. . The content data that can be recorded and reproduced by the terminal device 10 according to the present embodiment is audio content data or moving image content data. The CPU 11 exchanges control signals and data with each circuit unit via the bus 12.

  A ROM (Read Only Memory) 13 stores an operation program to be executed by the CPU 11, a program loader, various calculation coefficients, parameters used in the program, and the like. A program to be executed by the CPU 11 is expanded in a RAM (Random Access Memory) 20. It is also used as a data area and a task area that are necessary when the CPU 11 executes various processes. For example, the RAM 20 temporarily stores related information received by the terminal device 10 from the server.

  The operation input unit 15 includes operation keys, a jog dial, and various operators such as a touch panel provided on the casing of the terminal device 10. Note that a keyboard and mouse for GUI (Graphical User Interface) operation may be provided as the operation input unit 15. Information input by the operation input unit 15 is subjected to predetermined processing in the input processing unit 14 and transmitted to the CPU 11 as an operation command. The CPU 11 performs necessary computations and controls so that an operation as a device in response to the input operation command is obtained.

  As the display device 17, for example, a display device such as a liquid crystal display is connected to display various information. When the CPU 11 supplies display data to the display processing unit 16 according to various operation states, input states, and communication states, the display processing unit 16 causes the display device 17 to execute a display operation based on the supplied display data. For example, the display device 17 displays content distributed from the server, content-related information, clip information, and the like. In addition, when a search for music is performed via the network 30, the search result is displayed on the display device 17.

  The media drives 19a and 19b are drives that can record and reproduce content such as music recorded on a portable recording medium (there may be only reproduction depending on the recording medium). Note that the type of recording medium that can be recorded or reproduced by each of the media drives 19a and 19b is not limited to one type. That is, recording and reproduction can be performed on a plurality of types of recording media. For example, the media drive 19a performs CD / DVD playback, and the media drive 19b performs MD recording / playback.

  The portable recording medium for recording content such as music is not limited to an optical recording medium such as a CD or a DVD. For example, content can be recorded on a recording medium constituted by a semiconductor memory such as a flash memory. In that case, a reader / writer of the flash memory is connected to the bus 12.

  The user inserts a recording medium (CD, DVD, MD, etc.) on which arbitrary content is recorded into the media drives 19a and 19b, and performs a predetermined operation of the remote controller 40 or the operation input unit 15, thereby playing the music. You can appreciate it. For example, when the user operates the remote controller 40 and gives a playback instruction using the media drive 19a, the CPU 11 instructs the media drive 19a to play back the content. In response to this, the media drive 19a accesses and reads the designated content from the loaded recording medium.

  If the content read out in this way is audio content, it is transferred to the audio data processing unit 24 after being subjected to decoding processing or the like by processing of the CPU 11 as necessary. The audio data processing unit 24 performs processing such as sound field processing such as equalizing, volume adjustment, D / A conversion, amplification, and the like, and outputs from the speaker unit 25. The speaker unit 25 includes a plurality of speakers 25a and 25b as shown in FIG. 5, and can output sound in stereo.

  Further, the content reproduced by the media drives 19a and 19b can be stored as an audio data file in the HDD 21 under the control of the CPU 11. The audio data file format may be 16-bit quantized digital audio data with a sampling frequency of 44.1 KHz in the CD format. In order to save the capacity of the HDD 21, it may be compressed audio data in a format subjected to compression processing according to a predetermined method. Further, the compression method is not limited, but an ATRAC (Advanced TRansform Acoustic Coding (trademark)) method, an MP3 (MPEG Audio Layer-3) method, or the like can be adopted.

  The tuner 27 is an AM / FM radio tuner, for example, and demodulates the broadcast signal received by the antenna 26 based on the control of the CPU 11. Of course, a tuner such as a TV tuner, a satellite broadcast tuner, or a digital broadcast tuner may be used. The demodulated broadcast signal is subjected to required processing in the audio data processing unit 24 and is output as broadcast sound from the speaker unit 25. Alternatively, a required process is performed in the display processing unit 16 and displayed on the display device 17.

  The communication processing unit 22 performs transmission data encoding processing and reception data decoding processing based on the control of the CPU 11. The network interface 23 transmits the transmission data encoded by the communication processing unit 22 to a predetermined external network compatible device via the network. In addition, the network interface 23 delivers information transmitted from the external network compatible device via the network to the communication processing unit 22.
