  The CPU 81 executes and executes various programs stored in the ROM 85 in accordance with input signals input from each unit of the DVD recorder 100, remote control signals input by pressing various buttons in the key input unit 1, and the like. The overall operation of the DVD recorder 100 is comprehensively controlled by outputting an output signal to each unit based on the program.

  The RAM 83 is used as a work area for the CPU 81, and temporarily stores processing results generated when various programs are executed by the CPU 81, input data, and the like.

The EEPROM 84 includes an attribute memory 841 that stores attribute information related to the attribute of character data determined by a determination program 85f (described later).
In the execution of the storage program 85g, the attribute memory 841 counts the number of selections selected by execution of the selection program 84d (described later) as attribute information for each attribute of character data determined by execution of the determination program 85f. I remember it. Thereby, the attribute memory 841 constitutes a part of the storage means. The attribute memory 841 will be described in detail together with the description of the storage program 85g described later.

  The ROM 85 has a program storage area composed of a non-volatile memory. Specifically, the reception program 85a, the first recording program 85b, the display program 85c, the selection program 84d, the first creation program 85e, the determination program 85f, A storage program 85g, a specific program 85h, a second creation program 85i, a second recording program 85j, and the like are stored.

The reception program 85a is, for example, a program for causing the CPU 81 to realize a function of receiving digital broadcast data in which program content and program information related to the program content are multiplexed.
Specifically, when an operation for instructing recording of a program is performed in the key input unit 1, the CPU 81 tunes the tuner 2 to a specific frequency band and multiplexes program content and program information related to the program content. The digital broadcasting data TS is received. Furthermore, the program content to be recorded and the packet of program information related to the program content are acquired from the received TS and output to the encoder unit 3.
The CPU 81 functions as a receiving unit together with the tuner 2 by executing the receiving program 85a.

The first recording program 85b is, for example, a program for causing the CPU 81 to realize a function of recording program content included in digital broadcast data received by execution of the reception program 85a.
Specifically, the CPU 81 encodes the program content acquired by the tuner 2 into a file format that can be recorded on the DVD 51 by the encoder unit 3, and performs error correction encoding, 8-16 modulation, etc. by the DVD signal processing unit 4. The DVD drive unit 5 records on the DVD 51.
The CPU 81 functions as the first recording unit together with the DVD drive unit 5 by executing the first recording program 85b.

For example, the display program 85c displays, on the display unit 200a, program information relating to the program content recorded by the execution of the first recording program 85b, extracted from the digital broadcast data received by the execution of the reception program 85a. This is a program for realizing the function to be performed.
The CPU 81 functions as a display unit by executing the display program 85c.

The selection program 84d is, for example, a program for causing the CPU 81 to realize a function of allowing the user to select character data from program information displayed on the display unit 200a by executing the display program 85c.
The CPU 81 functions as a selection unit together with the key input unit 1 by executing the selection program 84d.

The first creation program 85e is a program for causing the CPU 81 to realize a function of creating first title information including character data selected by executing the selection program 84d, for example.
The CPU 81 functions as a first creation unit by executing the first creation program 85e.

  Here, the creation process of the first title information by executing the display program 85c, the selection program 84d, and the first creation program 85e will be specifically described with reference to FIGS.

The creation of the first title information is performed, for example, when the user instructs recording of program content. For example, when the recording of the program content “Love is shaking (title before editing)” is instructed, the CPU 81 first displays the OSD screen illustrated in FIG. 3 on the display unit 200a. On the OSD screen of FIG. 3, it is possible to select “not edit”, “edit by yourself”, and “automatically edit” for the title.
On the OSD screen of FIG. 3, for example, when “not edit” is selected, the title “love is shaken” before editing is directly used as the title information of the program content. When “Edit by yourself” is selected, the display program 85c, the selection program 84d, and the first creation program 85e are executed, and title information corresponding to the user's operation is created (hereinafter, the user selects Title information to be created is referred to as “first title information (title information)”. Further, when “automatically edit” is selected, a second creation program 85i described later is executed to automatically create title information (hereinafter, automatically created title information is “ Second title information).

  As described above, when “edit by yourself” is selected, the CPU 81 selects the program content that is the target of the creation of the first title information from the program information received by the execution of the reception program 85a. Extract related program information. Then, as shown in FIG. 4, a title information creation screen based on the read program information is displayed on the display unit 200a, and the program information related to the selected program content is presented to the user.

In the title information creation screen of FIG. 4, as program information of the selected program content, for example, title before editing, broadcast station, channel, broadcast date / time, genre, broadcast type, video aspect, audio system, rating information, copy Information, contract information, detailed program information (performer, director, program content, etc.) are displayed in the program information display area. A cursor is displayed in the program information display area, and the cursor key 1e of the key input unit 1 can be freely moved up and down and left and right to arbitrarily select from program information displayed on the title information creation screen. Characters can be specified.
In addition to the program information display area, the title information creation screen includes a title display area in which title information being edited is displayed, a registered character list area in which a list of character data selected from the program information is displayed in the order of selection, etc. Is provided.

For example, in the title information creation screen of FIG. 4, when adding an arbitrary character “1996 public works” included in the program information to the title “Love is shaking” before editing, the user in the program information display area, By designating the start position and end position of the character “1996 public works” to be selected, a range including the character to be selected is specified. Specifically, the user moves the cursor on the program information display area to the start position of the specified range including the character to be specified, confirms the position with the enter key 1f, and moves the cursor to the end position of the specified range. Is moved and the position is confirmed by the enter key 1f. Thereby, the character data “1996 public works” is selected.
Then, as shown in FIG. 5, in the program information display area, the selected character “1996 public works” is highlighted by screening or the like. In the title display area, the selected character “1996 public works” is added to the pre-edited title “Ai is shakes”, and the display is changed to “Ai is shakes 1996 works”. Further, in the registered character list area, the selected character “1996 public works” is displayed as the first selected character data.

Further, in the case where an arbitrary character “aabbcc” is further added to the title information “Ai wa wa sei 1996 release” added with the selected character data, the user wants to select the character “ The range is specified by specifying the start position and end position of “abbcc”. As a result, the character data “aabbcc” is selected.
Then, as shown in FIG. 6, in addition to the already selected character “1996 public works”, the newly selected character “aabbcc” is highlighted in a program information display area by screening or the like. In the title display area, the selected character “aabbcc” is added to “Ai wa wa swing 1996 published work”, and the display is changed to “Ai wa wa swing 1996 published work aabbcc”. Further, in the registered character list area, the newly selected character “aabbcc” is displayed as the second selected character data.
Thus, each time character data is selected from the program information in the program information display area on the title information creation screen, the selected character data is added to the title information before editing in the order of selection. It will be.

Furthermore, when changing the order of adding already selected character data, the user can freely change the order of adding character data by changing the order displayed in the registered character list display. Specifically, for example, when the order of addition of “1996 public works” and “aabbcc” is switched, the user moves the cursor on the registered character list area to the character data column to be moved by the cursor key 1e. Move and press the enter key 1f to select the character data. Then, after the selected character data is moved to the position to be moved by the cursor key 1e, the determination key 1f is pressed again. Then, as shown in FIG. 7, the order of the two character data displayed in the registered character list area is switched, and the display of the title display area is changed from “love is shaken 1996 work aabbcc” to “love is shaken aabbcc 1996”. Yearly release work "
Then, when the user presses the enter key 1f, the title information “Love is shaking aabbcc 1996 published work” displayed in the title display area is confirmed as the first title information.

  The timing for creating the first title information is not limited to when the recording of the program content is instructed, and may be any time before, during, or after the recording of the program content. For example, when the creation of the first title information is instructed after recording the program content, the CPU 81 displays a list of the program content recorded on the DVD 51 on the display unit 200a, and the program whose title is edited from the list. Let the user select content. Then, the program information related to the selected program content is read from the program information stored in advance in the DVD 51, an EPG memory (not shown), etc., and a title information creation screen is displayed on the display unit 200a based on the read program information. 1 Title information is created.

The determination program 85f is a program for causing the CPU 81 to realize a function of determining the attribute of character data selected by executing the selection program 84d, for example.
Specifically, when character data is selected from the program information on the title information creation screen displayed by executing the above-described selection program 84d, the CPU 81 determines the attribute of the selected character data. The attributes of the character data include, for example, a performer, a director, a broadcast station, a channel, a broadcast date and time, a genre, a broadcast type, a video aspect, an audio system, rating information, copy information, contract information, program detail information The year of release, the country of production, etc. are determined using program information and the like. Further, a keyword prepared in advance for each attribute may be used for discrimination. For example, the country name of each country is stored in advance as a keyword of the country of production, and the country of production is determined by detecting items matching these keywords from the program detailed information.
For example, the attributes of the text data “1996 public works” and “aabbcc” selected in the first title information creation process illustrated in FIGS. 4 to 7 are determined as “publication year” and “director”, respectively. .
The CPU 81 functions as a determination unit by executing the determination program 85f.

The storage program 85g is, for example, a program for causing the CPU 81 to realize a function of storing attribute information related to the attribute of character data determined by executing the determination program 85f. The storage program 85g counts and stores, as attribute information, the number of selections selected by executing the selection program 84d for each attribute of character data determined by executing the determination program 85f.
Specifically, as shown in the attribute memory 841 in FIG. 8, the CPU 81 has attributes of character data that can be selected from the program information (broadcast station, channel, broadcast date / time, genre, broadcast type, video aspect, audio system, rating). Information, copy information, contract information, performers, directors, release year, production country, etc.). Then, when the character data is selected in the execution of the selection program 84d and the attribute of the character data selected by the execution of the determination program 85f is determined, the number of selections of the determined attribute is incremented and stored. That is, for example, in the attribute memory 841 illustrated in FIG. 8, it is stored that character data whose attribute is “publication year” has been selected four times in the past.
The CPU 81 functions as a storage unit together with the attribute memory 841 by executing the storage program 85g.

The specifying program 85h is, for example, a program for causing the CPU 81 to realize a function of specifying the character data attribute selected by the user as the user selection attribute based on the character data attribute information stored by executing the storage program 85g. It is. The identification program 85h identifies an attribute of character data whose number of selections as attribute information is a predetermined number or more as a user selection attribute.
Specifically, when the number of times of selection of each attribute stored in the attribute memory 841 is a predetermined number of times (for example, 5 times) or more, the CPU 81 has selected the attribute more in the past. It is specified as an attribute (user selection attribute). For example, in the attribute memory 841 illustrated in FIG. 8, the attributes “genre”, “performer”, “director”, and “publication year” of the character data whose number of selections selected in the past is 5 or more are user selection attributes. Has been identified.
The CPU 81 functions as specifying means by executing the specifying program 85h.

The second creation program 85i includes, for example, the extracted character data obtained by extracting, from the program information, character data that matches the user selection attribute based on the user selection attribute specified by the execution of the specification program 85h. It is a program for realizing a function of creating second title information.
The second creation program 85i is executed, for example, when “automatic editing” is selected on the OSD screen of FIG. 3 displayed on the display unit 200a when an instruction to record program content is given. When the CPU 81 detects that “automatic editing” is selected on the OSD screen of FIG. 3, the program for which the second title information is to be created from the program information received by the execution of the reception program 85a. Program information related to the content is extracted. Further, the attribute memory 841 is accessed, the attribute specified as the user selection attribute is read, and character data having the specified user selection attribute is extracted from the program information.
For example, when creating the second title information of the title “Meidoru Taro” before editing, if the specified user selection attribute is “Genre”, “Performer”, “Director”, “Publication Year”, the CPU 81 determines from the program information. Character data matching these user selection attributes is detected. Thus, for example, character data “movie” that matches the user selection attribute “genre”, character data “gghhi” that matches the user selection attribute “performer”, and character data “jjkkll” that matches the user selection attribute “director” The character data “2001” that matches the user selection attribute “publication year” is extracted. Further, the CPU 81 adds the character data extracted from the program information in accordance with the user selection attribute to the pre-edited title “Meidoru Tarou”, thereby creating the second title information “Meidoro Tarou movie gghhi jjkkll 2001”. To do.
The CPU 81 functions as second creation means by executing the second creation program 85i.

The second recording program 85j, for example, gives the CPU 81 the first title information created by executing the first creating program 85e or the second title information created by executing the second creating program 85i. Is a program for realizing the function of recording in association with the program content recorded by the execution of. When the first title information is not created by executing the first creation program 85e, the second recording program 85j uses the second title information created by executing the second creation program 85i to execute the first recording program 85b. Is recorded in association with the program content recorded by.
Specifically, when the first title information (for example, “love is shaking aabbcc 1996 published work”) is created by the execution of the first creation program 85e, the CPU 81 stores the first title information in the encoder unit 3 Then, the data is supplied to the DVD drive unit 5 via the DVD signal processing unit 4, and is stored in the DVD 51 in association with the program content in the DVD drive unit 5. Further, when the second title information (for example, “Mameji Taro movie gghhi jjkkll 2001”) is created by executing the second creation program 85i, the second title information is sent to the encoder unit 3 and the DVD signal processing unit 4. To the DVD drive unit 5, and the DVD drive unit 5 stores it in the DVD 51 in association with the program content.
The CPU 81 functions as a second recording unit together with the DVD drive unit 5 by executing the second recording program 85j.

Thus, for example, as shown in FIG. 9, in the list of program contents recorded on the DVD 51, the first title information created by adding the character data selected by the user to the original title, and the past The second title information created by automatically adding the character data based on the user's selection tendency is presented as title information together with data such as the recording date. That is, since the information desired by the user is included in the title information, the user can easily view the recorded program content at a glance without replaying the program content and checking the content or referring to the program information. Can grasp.
In the list of program contents illustrated in FIG. 9, each title is created, that is, whether the title is an original title that has not been edited (“no editing”), or is the first title information created by the user himself / herself. ("Edit by yourself") or whether it is the automatically created second title information ("Automatic edit"). Select the creation method column and edit the title again. Or return to the original title.

  Next, referring to the flowcharts of FIGS. 10 and 11, the first title information creation process performed based on the user's selection and the second title automatically performed based on the user's selection tendency in the past Information creation processing will be described.

When the CPU 81 determines that the creation of the first title information is instructed in step S1 (step S1; Yes), the CPU 81 proceeds to step S2 and determines that the creation of the first title information is not instructed (step S1; No). Proceed to step S10.

In step S <b> 2, the CPU 81 acquires program information of program content for which first title information is to be created. In step S3, a title information creation screen based on the acquired program information is displayed on the display unit 200a.
In step S4, the user operates the key input unit 1 to designate a range from program information on the title information creation screen and select character data to be included in the title information. In step S5, the CPU 81 adds the character data selected by the user to the title information before editing to create first title information. In step S6, the created first title information is recorded on the DVD 51 in association with the program content.

  In step S7, the CPU 81 determines the attribute of the character data selected in step S4. In step S8, the CPU 81 increments the number of selections of the character data attribute stored in the attribute memory 841. Further, in step S9, the attribute with the number of selections stored in the attribute memory 841 is specified as a user selection attribute, the specified user selection attribute is stored in the attribute memory 841, and the process is terminated. To do.

  Next, in step S10 of FIG. 11, the CPU 81 acquires program information of the program content for which the second title information is to be created. In step S11, the CPU 81 extracts character data matching the specified user selection attribute from the acquired program information. In step S12, the character data extracted from the program information is added to the title information before editing to create second title information. Further, in step S13, the created second title information is recorded on the DVD 51 in association with the program content, and this process is terminated.

As described above, according to the DVD recorder 100 of the present embodiment of the present invention, the digital broadcast data in which the program content and the program information related to the program content are multiplexed is received by the execution of the reception program 85a.
