Take overall control.

The RAM 123 stores, for example, processing results generated when various programs are executed by the CPU 121, input data, and the like.
The playback position storage unit 124 is configured by an EPROM (Erasable Programmable ROM) or the like, and in the execution of the storage program 125e described later, a predetermined playback position of the video marked by the operation of the title creation key 1a is set for each program (series). To remember.

  The ROM 125 has a program storage area composed of a non-volatile memory. Specifically, the reception program 125a, the recording program 125b, the reproduction program 125c, the marking program 125d, the storage program 125e, the acquisition program 125f, the creation program 125g, etc. Is remembered.

For example, the reception program 125a is a program for causing the CPU 121 to realize a function of receiving first content data including video data and second content data belonging to the same series as the first content data.
Specifically, when the key input unit 1 performs an operation to instruct recording of a program, the CPU 121 tunes the tuner 2 to a specific frequency band and receives a broadcast signal. Further, when recording of a series-type program is reserved, the broadcast signal of the program is received from the broadcast start time of the reserved program to the broadcast reception time. Furthermore, TS packets (content data, first content data, and second content data) of the recorded program are acquired from the received TS and output to the encoder unit 3.
The CPU 121 functions as a receiving unit together with the tuner 2 by executing the receiving program 125a.

The recording program 125b is, for example, a program for causing the CPU 121 to realize a function of recording the first content data and the second content data received by executing the reception program 125a.
Specifically, the CPU 121 encodes the first content data or the second content data extracted by the tuner 2 into a file format that can be recorded on the DVD 61 by the encoder unit 3, and the data processor 5 performs error correction coding. , 8-16 modulation or the like is performed, and the DVD drive unit 6 records on the DVD 61. The CPU 121 records programs belonging to the same series in association with each other.
The CPU 121 functions as a recording unit together with the DVD drive unit 6 by executing the recording program 125b.

The reproduction program 125c, for example, realizes a function of causing the CPU 121 to reproduce the first content data and the second content data recorded by the execution of the storage program 125e and display a video based on the video data on the display unit 300a. It is a program to make it.
Specifically, when an operation for instructing reproduction of a program recorded on the DVD 61 is performed in the key input unit 1, the CPU 121 causes the DVD drive unit 6 to execute content data (first data) recorded on the DVD 61. Content data or second content data) is read out, subjected to 8-16 demodulation, error correction decoding, and the like, and sent to the decoder unit 7. Further, after the separation unit 71 separates the video stream, the audio stream, and the data stream, the video decoder 72, the audio decoder 73, and the data decoder 74 decode the streams, respectively, and the television receiver connected to the apparatus main body. Output to the display unit 300a and the speaker 300b of the machine 300.
The CPU 121 functions as a playback unit by executing the playback program 125c.

For example, the marking program 125d is a program for causing the CPU 121 to realize a function of marking a video displayed on the display unit 300a when the first content data is reproduced by executing the reproduction program 125c.
Specifically, during playback of the first content data, the user looks at the playback video displayed on the display unit 300a of the television receiver 300 while the characters and video that are desired to be included in the title information are displayed. Then, the title creation key 1a of the key input unit 1 is pressed. Then, based on the pressing of the title creation key 1a, the CPU 121 determines the playback video displayed on the display unit 300a as the marking video when the key is pressed.
The CPU 121 functions as a marking unit together with the title creation key 1a by executing the marking program 125d.

The storage program 125e is, for example, a program for causing the CPU 121 to realize a function of storing a predetermined reproduction position at which the video marked by the execution of the marking program 125d in the first content data is reproduced.
Specifically, when the playback video displayed on the display unit 300a when the title creation key 1a is pressed by the execution of the marking program 125d is determined as the marking video by the execution of the marking program 125d, the CPU 121 Determine the playback position.
Here, the predetermined reproduction position may be a position having a predetermined width including the marking video at the time when the title creation key 1a is operated, and the marking video at the time when the title creation key 1a is operated is pinned. It may be a position indicated by a point. The predetermined reproduction position is indicated by, for example, an elapsed time from the start of program broadcasting. When the reproduction position is determined, the CPU 121 causes the reproduction position storage unit 124 to store information relating to the reproduction position (for example, elapsed time data from the start of broadcast of the program) together with identification information of the program (series).
The CPU 121 functions as a storage unit together with the reproduction position storage unit 124 by executing the storage program 125e.

The acquisition program 125f acquires, for example, the video data of the image marked by the execution of the marking program 125d in the first content data in the CPU 121 and based on the predetermined reproduction position stored by the execution of the storage program 125e. This is a program for realizing a function of acquiring video data included in the second content data.
Specifically, when reproducing the first content data, the CPU 121 stores the first content data when the reproduction position of the image marked based on the depression of the title creation key 1a is stored in the reproduction position storage unit 124. The marked video data (see FIG. 3) is obtained from the DVD 61.
In addition, when the tuner 2 receives the first content data and the second content data belonging to the same series, the CPU 121 stores the second content data in the analysis unit 4 by executing the storage program 125e. Video data (see FIG. 4) at the reproduced position is acquired.
Here, since the second content data is a program belonging to the same series as the first content data, the video at the reproduction position (FIG. 5) obtained from the second content data and stored by the execution of the storage program 125e. 4) is likely to be the same video as that marked at the time of reproduction of the first content data (see FIG. 3), and includes characters and video to be included in the title information in the same manner as the marked video. There is a high possibility that the video is in line with the user's intention.
The CPU 121 functions as an acquisition unit together with the DVD drive unit 6 and the analysis unit 4 by executing the acquisition program 125f.

The creation program 125g is, for example, the title information of the first content data and the title of the second content data recorded by the execution of the recording program 125b based on the video data acquired by the CPU 121 by the execution of the acquisition program 125f. It is a program for realizing the function of creating information. The creation program 125g acquires character data included in the video data acquired by executing the acquisition program 125f, and generates title information including at least a part of characters based on the character data, or the acquisition program 125f A thumbnail image of the video based on the video data acquired by execution is created, and title information including the thumbnail image is created.
The CPU 121 functions as a creation unit by executing the creation program 125g.

  The title information creation method is selected in advance by the user on the menu screen illustrated in FIG. In FIG. 2, one of a method of creating title information including characters included in the video marked by the title creation key 1a and a method of creating title information including a thumbnail image of the video marked by the title creation key 1a are selected. can do.

First, a specific description will be given of a case where title information including characters included in a marked video is created in the execution of the creation program 125g.
When the title creation key 1a is pressed during playback of the first content data, the CPU 121 takes in still video data of a playback video (see FIG. 3) at the time when the title creation key 1a is pressed from the DVD 61. Then, the captured video data is output to the character recognition unit 8 to extract text data (for example, “To * s and Go * n characters: To * s and Go * n”) included in the video data. Then, the extracted text data is output to the title information creation unit 10, and title information is created based on the text data.
In the title information creation unit 10, for example, a series name (for example, “Tous and Tokamachi”) included in additional information (program sequence information) transmitted together with content data, and text data extracted from video data Is combined with a part (for example, “To * s and Go * n”) to obtain title information (for example, “To * s and Kamaton To * s and Go * n”).
In addition, for example, the series name included in the additional information transmitted together with the content data is not included in the title information, but the text data extracted from the video data is used as the title information (for example, “Toss and Goon characters names : To * s, Go * n]).
When the title information is created by the title information creation unit 10, the CPU 121 outputs the title information to the DVD drive unit 6 via the data processor 5 and records it on the DVD 61 in association with the first content data.

In addition, when reception of second content data belonging to the same series as the first content data for which title information has been created is started, the CPU 121 analyzes the second content data in the analysis unit 4 and stores it. Still image data of a reproduced image (see FIG. 4) at a reproduction position stored by executing the program 125e is captured. Then, the captured video data is output to the character recognition unit 8, and text data included in the video data (for example, “Aka Hana no J * S character name: J * S ○ ○, training ○-"). Then, the extracted text data is output to the title information creation unit 10, and title information is created based on the text data.
Similar to the title information creation method performed for the first content data, the title information creation unit 10, for example, includes a series name (for example, “Toss”) included in the additional information transmitted together with the content data. ”And the text data extracted from the video data (for example,“ Akahana no J * S ”) and the title information (for example“ J * S ')).
In addition, for example, the series name included in the additional information transmitted together with the content data is not included in the title information, but the text data extracted from the video data is used as the title information (for example, “Akahana no J * S character name: J * S, ○, ○, ○, ○, and ○ ○ ”).
When title information is created by the title information creation unit 10, the CPU 121 outputs the title information to the DVD drive unit 6 via the data processor 5, and records it on the DVD 61 in association with the second content data.

  Note that title information may be created by distinguishing types such as a series name extracted from additional information, a subtitle extracted from video data, and a character name extracted from video data (for example, “series name: Sutonama Tachibana Subtitle: Akahana no J * S Characters: J * S, * Cook, * Lu, * Non, * Ko, Tore *)).

5 and 6 are diagrams illustrating examples of title information displayed on the display unit 300a of the television receiver 300 when title information including characters included in the marked video is created.
In FIG. 5, a series name (for example, “Tous and Tokamachi”) included in additional information (program layout information) transmitted together with content data and a part of text data extracted from video data (for example, , “To * s and Go * n” and “Akahana no J * s”) are combined into title information.
In FIG. 6, the series name included in the additional information (program arrangement information) transmitted together with the content data is not included in the title information, and text data extracted from the video data (for example, “TOS and GO ○ Character name: To * s, Go * n "/" Akahana no J * s Character name: J * s, * Cok, * Lu, * n, * Ko, Tore * "" It is considered as title information

Next, a case where title information including a thumbnail image of a marked video is created in the execution of the creation program 125g will be specifically described.
When the title creation key 1a is pressed during playback of the first content data, the CPU 121 takes in still video data of a playback video (see FIG. 3) at the time when the title creation key 1a is pressed from the DVD 61. Then, the captured video data is output to the thumbnail image creation unit 9, and the video data is reduced to create a thumbnail image. Then, the created thumbnail image is output to the title information creating unit 10, and title information is created based on the thumbnail image.
For example, the title information creation unit 10 adds this thumbnail image to a series name (for example, “Toss and Tokamachi”) included in additional information (program layout information) transmitted together with content data. Use title information.
When the title information is created in the title information creation unit 10, the CPU 121 outputs the title information to the DVD drive unit 6 via the data processor 5 and records it on the DVD 61 in association with the first content data.

In addition, when reception of second content data belonging to the same series as the first content data for which title information has been created is started, the CPU 121 analyzes the second content data in the analysis unit 4 and stores it. Still image data of a reproduced image (see FIG. 4) at a reproduction position stored by executing the program 125e is captured. Then, the captured video data is output to the thumbnail image creation unit 9, and the video data is reduced to create a thumbnail image. Then, the created thumbnail image is output to the title information creating unit 10, and title information is created based on the thumbnail image.
For example, the title information creation unit 10 adds this thumbnail image to a series name (for example, “Toss and Tokamachi”) included in additional information (program layout information) transmitted together with content data. Use title information.
When the title information is created in the title information creation unit 10, the CPU 121 outputs the title information to the DVD drive unit 6 through the data processor 5 and records it on the DVD 61 in association with the second content data.

(Embodiment 2)
Next, Embodiment 2 of the present invention will be described in detail with reference to the drawings.
The recording / reproducing apparatus of the second embodiment will be described as being a DVD recorder, for example, as in the first embodiment.
In addition, about the structure similar to Embodiment 1, the same code | symbol is attached | subjected and the description is abbreviate | omitted.

First, the main configuration of the DVD recorder 200 according to the second embodiment will be described with reference to FIG.
For example, the DVD recorder 200 receives a broadcast signal transmitted from the key input unit 1 and the broadcast station, selects a broadcast signal of a predetermined broadcast channel from the broadcast signal, and selects content data (first Tuner 2 for extracting content data, second content data), encoder unit 3 for performing predetermined compression processing on content data input from tuner 2, and content data input from tuner 2 to analyze video data The content data input from the encoder unit 3 is supplied to the DVD drive unit 6, and the content data taken from the DVD drive unit 6 is supplied to the decoder unit 7. Record and playback broadcast program data to the supplied data processor 5 and DVD 61. DVD drive unit 6, decoder unit 7 for performing predetermined expansion processing on broadcast program data output from DVD drive unit 6, character recognition unit 8 for recognizing characters included in video data, and thumbnail for creating a thumbnail image from video data Based on text data input from the image creation unit 9 and the character recognition unit 8, thumbnail image input from the thumbnail image creation unit 9, and additional information input from the video decoder 72 (program sequence information (SI: Service Information)) A title information creating unit 10 that creates title information, a mixing unit 11 that synthesizes OSD data and the like into a video signal, a control unit 14 that controls the entire DVD recorder 200, and the like.

The key input unit 1 is, for example, a remote controller that remotely operates the device main body, and generates a remote control signal based on pressing of various keys and outputs the remote control signal to the control unit 14 of the device main body.
The key input unit 1 is provided with a title creation key 1a for marking a desired reproduced video and instructing creation of a title when reproducing the first content data. When the title creation key 1a is operated, a marking program 125d, a storage program 143a, an acquisition program 143b, and a creation program 125g described later are executed, and title information of the first content data based on the marked reproduction video is created. The Rukoto.

When title information of the first content data is created by operating the title creation key 1a, title information of the second content data belonging to the same series as the first content data is created.
In particular, in the second embodiment, the marked video in the first content data is stored, not the reproduction position of the marked video in the first content data as in the first embodiment. Then, the second content data is analyzed, the reproduction position of the stored video in the second content data is detected, and the title information of the second content data is based on the video data of the detected reproduction position. Created.

  The analysis unit 13 analyzes the TS as the second content data input from the tuner 2, detects the playback position of the video stored by executing the storage program 143a (described later), and detects the detected playback position Get video data.

  The control unit 14 includes a CPU (Central Processing Unit) 141, a time measuring unit 122 that measures the current time, a RAM (Random Access Memory) 123, a marking video storage unit 142, a ROM (Read Only Memory) 143, and the like. Yes.

  The CPU 141 executes various programs stored in the ROM 143 in accordance with input signals input from the respective units, and outputs output signals to the respective units based on the execution programs, so that the entire operation of the DVD recorder 200 is performed. Take overall control.

The RAM 123 stores, for example, processing results generated when various programs are executed by the CPU 141, input data, and the like.
The marking video storage unit 142 is configured by an EPROM (Erasable Programmable ROM) or the like, and stores the video marked by the operation of the title creation key 1a in the execution of the storage program 143a described later for each program (for each series).

  The ROM 143 has a program storage area composed of a non-volatile memory. Specifically, the reception program 125a, recording program 125b, reproduction program 125c, marking program 125d, storage program 143a, acquisition program 143b, creation program 125g, etc. Is remembered.

The storage program 143a is, for example, a program for causing the CPU 141 to realize a function of storing an image marked by execution of the marking program 125d in the first content data.
Specifically, when the playback video displayed on the display unit 300a at the time when the title creation key 1a is pressed is determined as a marking video by executing the marking program 125d, the CPU 141 selects the marking video as the marking video. The marking video storage unit 142 stores the program (series) identification information together with the program (series) identification information.
The CPU 141 functions as a storage unit together with the marking video storage unit 142 by executing the storage program 143a.

For example, the acquisition program 143b acquires, in the CPU 141, the video data of the video marked by the execution of the marking program 125d in the first content data, and the video stored by the execution of the storage program 143a is reproduced. This is a program for realizing a function of detecting a position and acquiring video data included in the second content data based on the detected reproduction position.
Specifically, the CPU 141 stores the marked video data in the first content data when the marked video is stored based on the depression of the title creation key 1a during the reproduction of the first content data. (See FIG. 3) is obtained from the DVD 61.
When the second content data belonging to the same series as the first content data is received by the tuner 2, the CPU 141 causes the analysis unit 13 to store the video stored by executing the storage program 143a (see FIG. 3). A video (see FIG. 4) having a similarity to the threshold value equal to or greater than a certain threshold is detected from the second content data. For example, the CPU 141 acquires, from the second content data, the video acquired from the first content data and the video having a matching degree of a background image / background color / background frame or the like greater than or equal to a predetermined threshold. Then, when a video similar to the marked video of the first content data is detected in the second content data, the second content data is based on the playback position of the detected video. To acquire the video data.
Here, since the second content data is a program belonging to the same series as the first content data, the video of the first content data (see FIG. 3) stored by the execution of the storage program 143a, and the screen configuration A video (see FIG. 4) in which the degree of similarity (character position, character size, background image, background color, background frame, etc.) is equal to or higher than a certain threshold is the same as the video marked when reproducing the first content data, There is a high possibility that the video is in line with the user's intention including the text and video to be included in the title information.
In the acquisition program 143b, when the video data is acquired from the second content data, both the similarity to the marked video in the first content data and the reproduction position may be considered.
The CPU 141 functions as an acquisition unit together with the DVD drive unit 6 and the analysis unit 13 by executing the acquisition program 143b.

According to the DVD recorder 200 in the second embodiment described above, the first content data including video data and the second content data belonging to the same series as the first content data are received by the execution of the reception program 125a. The first content data and the second content data received by the execution of the reception program 125a are recorded by the execution of the recording program 125b, and the first content data recorded by the execution of the recording program 125b is recorded by the execution of the reproduction program 125c. When the first content data and the second content data are reproduced and the video based on the video data is displayed on the display unit 300a and the first content data is reproduced by the execution of the reproduction program 125c by executing the marking program 125d, table The image displayed on the unit 300a is marked, and the image marked by execution of the marking program 125d in the first content data is stored by execution of the storage program 143a, and the first content is executed by execution of the acquisition program 143b. In the data, video data of a video marked by execution of the marking program 125d is acquired, and video stored by execution of the storage program 143a from second content data belonging to the same series as the first content data Is reproduced, and video data included in the second content data is acquired based on the detected reproduction position, and acquired by executing the acquisition program 143b by executing the creation program 125g. Based on the image data, title information of the first content data title information and the second content data recorded is generated by the execution of the recording program 125b. In addition, by executing the creation program 125g, character data included in the video data acquired by executing the acquisition program 143b is acquired, and title information including at least a part of characters based on the character data is generated or acquired by the program 143b. A thumbnail image of the video based on the video data acquired by executing is created, and title information including the thumbnail image is created.
Accordingly, when the reproduced video is marked during the reproduction of the content data, title information is created based on the video data of the video. Therefore, it is possible to create the title of the recorded content more in line with the user's intention by an easy operation using the video data included in the content data.
In addition, even if the user himself / herself does not input the title information, the title information desired by the user can be created simply by marking the desired playback video, which is very convenient for the user.
Furthermore, even information that is not included in the additional information sent together with the content data can be included in the title information, so that title information that is more desirable for the user can be created.

Further, when the title information is created by marking the playback video during playback of the first content data, the second content data belonging to the same series as the first content data is related to the first content data. A playback position where the marked playback video is played back is detected, and title information is created based on the video at the detected playback position.
That is, even if the marking operation is not performed for each piece of content data belonging to the same series, if the reproduced video is marked during reproduction of the first content data, each video of the second content data belonging to the same series Title information corresponding to the data is automatically created. Therefore, it is not necessary to create title information for each of the second content data belonging to the same series as the first content data, and the second content data does not need to be marked on the reproduced video of the second content data. Appropriate title information corresponding to each content data is created, which is more convenient for the user.
In addition, even when the video marked in the first content data is played back at a different playback position in the second content data, the second content data can be changed based on the video marked in the first content data. Since video data is detected and title information is created, title information desirable for the user can be created more reliably.

  Further, by executing the creation program 125g, character data included in the video data acquired by executing the acquisition program 143b is acquired, and title information including at least a part of characters based on the character data is generated. By marking a reproduced video on which characters to be included in information are displayed, desired character information can be included in the title information and more desirable title information can be created for the user.

  Further, by executing the creation program 125g, a thumbnail image of the video based on the video data acquired by the execution of the acquisition program 143b is generated, and title information including the thumbnail image is generated. By marking, a thumbnail image of a desired video can be included in the title information, and title information more desirable for the user can be created.

The present invention is not limited to the above embodiment, and various improvements and design changes may be made without departing from the spirit of the present invention.
For example, the title information created by the creating unit is not limited to that exemplified in the above embodiment. For example, only the title of the broadcast time may be used as title information, such as “To * s and Go * n”. In addition to the title of the broadcast and the name of the character, any information included in the video data or additional information such as a simple synopsis can be included in the title information.
