Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a video signal recording / reproducing apparatus such as a video tape recorder, a video disk recorder, etc., and in particular, at the time of reproduction, the content, that is, the recorded image can be visually and easily identified quickly. The present invention relates to a recording / reproducing device that is made possible.

[0002]

2. Description of the Related Art In a video signal recording / reproducing apparatus, content information is required to search for a target content, that is, a target recorded video, from the recording list. This content information includes the recording date / time / channel of recorded video, index image, and the like. Conventionally, there is a video tape recorder disclosed in Japanese Patent Laid-Open No. 2000-261755 as an example of a recording / reproducing apparatus configured to easily find a target content.

When this video tape recorder operates the recorded message call means, the reserved recorded program information including at least the recording date, the recording start time, and the channel specified by the recording reservation means for each reserved recording program, and the index image. The index images stored in the storage means are displayed as a list (list display) on the display device.

When a desired reserved recording program is selected based on the reserved recording program information or index image for each program displayed on the display device, the position of the index signal of the selected reserved recording program is searched. It is designed to play back at the beginning.

As described above, in the conventional video signal recording / reproducing apparatus capable of confirming this kind of content, the recorded program information (character string) such as recording date / time and recording channel is displayed on the display device, and thumbnails are displayed. There are those that display a representative image such as the above as an index image on a display device, and one that displays both the recorded program information and the index image like the video tape recorder described in the above publication.

FIG. 3 is a diagram showing an example in which recorded program information such as recording date / time, recording channel, etc. is displayed on a display device. FIG. 4 is a diagram showing an example in which a representative image such as a conventional thumbnail is displayed on a display device as an index image. FIG. 5 is a diagram showing an example in which both recorded program information such as recording date / time, recording channel, and the like, and an index image are displayed on a display device.

However, in the above-described conventional video signal recording / reproducing apparatus, when the recorded contents are displayed as a list on the screen of the display device, recorded program information, index images, or recorded images are displayed for all the displayed contents. The content information can be displayed in a list only by a uniform method / form such as a combination of program information and index images.

[0008]

By the way, when the recorded program information such as the recording date / time and the recording channel is suitable for the identification confirmation, the index image is the content information which is originally the decisive factor for searching the target content. There are various cases such as a case where it is suitable for the identification confirmation or a case where information such as a title is suitable for the identification confirmation, and it varies depending on individual contents.
Further, even for one content, different user may have different content information suitable for the search due to different recognition / impression of each content information by the user.

However, in the recording list by the above-mentioned conventional recording / reproducing apparatus, it is not possible to selectively display the content information suitable for the retrieval of the content individually.

That is, it is impossible to individually set the type of content information used for list display for retrieving content contents for each content, and the predetermined content information is unique and uniform for all contents. Since it is only comparatively displayed, it is not necessarily the optimum display in the sense of confirming the identification of the content.

As a result, in the recording list by the conventional recording / reproducing apparatus, the content information required as a decisive factor for the search is insufficient, and unnecessary content information that is not very useful for the search is also displayed. It wasn't very efficient.

[0012] For example, when a content having no image such as a radio broadcast or a content provided with only a still image is recorded, it is meaningless to display the index image as the content information in a list.

On the other hand, when there are sports programs, animations, dramas, etc. that are broadcast in the same time zone, it is easy to distinguish each index image as content information, but the recording date / time, recording channel, etc. When the recorded program information is used as the content information, it is difficult to be the decisive factor for identifying and confirming the target content.

In addition, in order to enable quick search, it is important to enhance the distinguishability of the content information of each content, and at the same time, to have a comprehensive view of all the content information at one time.

Therefore, if a large amount of content information is displayed for each content in order to increase the identification of each content, not only the visibility of each content information itself deteriorates, but also the number of contents displayed in one screen naturally. It is limited and results in having to page several times before finding the desired content, resulting in poor search efficiency.

Therefore, in displaying the content information for searching the target content by the recording / reproducing apparatus, it is required to display the efficient content information selected for each content. In addition, in order to improve the search efficiency, it is essential to improve the visibility as well as the distinguishability and the listability.

In view of the above problems, it is an object of the present invention to provide a recording / reproducing apparatus in which the content information to be displayed in the recording list can be individually selected for each content and the searchability by the recording list is improved. .

[0018]

In order to solve the above problems, the recording / reproducing apparatus of the present invention is a recording / reproducing apparatus capable of displaying a list of content information for each content recorded in a storage means on a display means. An index image extracting means for extracting the index image of the content recorded in the storage means and recording it as content information of the content, and recorded program information of the content recorded in the storage means as the content information of the content. A recording information management unit for recording and a content selected to be output at the time of list display from a plurality of content information of the content including the index image and the recorded program information for each recording of the content in the storage unit. The representative content information indicating the information is recorded, while each list is displayed when the list is displayed. Create a list screen based on the representative content information for each Ceiling, characterized in that it includes a content information recording managing means for displaying on the display means.

Thus, the recording / reproducing apparatus of the present invention can display only the content information, which is the decisive factor for the identification of each content, on the recording list screen. Further, the recording / reproducing apparatus of the present invention is characterized by further comprising a title input assisting means that enables a user to input a title as content information to the recorded content.

This allows the user to freely set a title convenient for content identification as the representative content information. Further, the recording / reproducing apparatus of the present invention is characterized by including display form adjusting means for displaying the respective representative content information in the same size on the display means regardless of the type of the respective representative content information. .

As a result, in the recording / reproducing apparatus of the present invention, even if the content information displayed on the recording list screen is different for each content, the appearance of the entire list is not deteriorated and the visibility is not deteriorated.

In response to the input of this control signal, 2 extracts a still image from a video input, that is, a recorded image stored in the storage means 11 according to a predetermined procedure, and uses this as an index image (that is, a representative image). Storage means 11
Correspond to the recorded image recorded in. For example,
The index image extraction means 12 extracts a still image of a video input after a lapse of a predetermined time from the start of recording as an index image, and records it in association with the recorded image of the video input of the storage means 11. If an index image is specified for the content by the content supplier, the specified image may be recorded as an index image in association with the recorded image of the video input.

By inputting this control signal, the recording information management means 13 receives the recording date / time of the video input.
The recording program information such as the recording channel is stored in the storage means 11
It is recorded in association with the recorded image of the relevant video input.

As a result, the recording / reproducing apparatus 1 of the present embodiment
Then, each time a video input is stored in the storage unit 11, that is, each time of recording, the storage unit 11 stores an index image and recorded program information such as recording date / time and recording channel in association with each recorded image, that is, each content. And are recorded as the content information of the content.

Further, the content information record managing means 16
When recording is performed based on the recording operation input of the remote controller and the key, based on the control signal output from the control means 15, content information (recorded program such as index image, recording date / time and recording channel) is obtained for each content. The storage means 11 stores content information management data composed of information, the total number of types of titles (which will be described later by a user input), type, and representative content information indicating which content information is selected for display in list display.
And record it in relation to the relevant content.

The representative content information in the content information management data has a predetermined default value until the user individually sets / changes the type of content information to be displayed at the time of list display. This default value is Any one of the content information that is always recorded at the time of recording, and in the present embodiment, any one of the recorded program information such as the index image, the recording date / time and the recording channel, is designated.

To input a title, the user operates the remote controller or the key to input the title of the content already recorded in the target storage means 11 or the content reserved for recording set in the control means 15. By designating, a control signal is supplied from the control means 15 to the title input support means 18,
This is done using the display screen of the display device.

That is, the title input support means 18 is
When a control signal for inputting a title is supplied from the control means 15, a title input means such as a software keyboard and a kana-kanji conversion system is provided as a video output on the screen of the display device via the OSD generation video memory 19. To do.

The user operates the software keyboard or the like appearing on the screen with the remote controller or the keys to input the title or the like. As a result, the input title or the like is supplied from the control means 15 to the content information record management means 16, and is associated with the corresponding content in the same manner as the other content information, and is stored in the storage means 11.
Recorded in.

At this time, the newly input title is designated as the representative content information by overwriting the existing representative content information. This is the title entered by the user
Compared to the content information that is automatically added as described above,
This is because it is important for the user to identify the content.

As a result, when recording is performed, it is composed of at least the index image extracted by the index image extracting means 12 and recorded program information such as recording date / time and recording channel managed by the recording information managing means 13. Two types of content information are recorded in the storage means 11 in association with the recorded video, that is, the content.

On the other hand, in the case of displaying a list of recorded images, that is, contents, when the user operates the remote controller or the keys to display the list, a control signal for displaying the list is sent from the control means 15 to the content information recording management means 16. Content information record management means 1
6 first reads the above-mentioned content information management data from the storage means 11.

Next, according to the representative content information of the content information management data, the selected content information is read from the storage means 11. By the two-step procedure by the content information recording management means 16, the content information selected as the representative content information for each content is read, and only the read content information can be displayed on the recording list. .

Then, the content information record management means 16
Displays the read content information on the display form adjusting means 1

When the content information is supplied from the content information record managing means 16, the display form adjusting means 17 aggregates the information within a predetermined display range. Therefore, the display mode adjusting means 17 divides the paragraphs by the number of characters or the paragraph breaks for each item of display content. And so on. At this time, since the display range (display area) is limited, the display content may be limited.

Then, the content information whose display form as a list has been adjusted by the display form adjusting means 17 once becomes O.
The SD generated video memory 19 is expanded and stored. These series of operations are repeated until one list screen is completed for all contents recorded in the storage means 11, and after one list screen is completed, OSD is performed.
The generated video memory 19 outputs the image of the list screen through the adder 20, and the list screen is provided to the user on the display screen of the display device.

FIG. 2 is a diagram showing an example of a list screen displayed on the display device by the recording / reproducing apparatus 1 of the present embodiment. In FIG. 2, screen 3 of the display device
0, some contents use index images 41, some contents use recorded program information 42 such as recording date / time and recording channel, and some contents use title 43 input by the user to list each contents information. Is displayed.

Therefore, although the displayed list is a mixed display of various content information, display of each selected content information is predetermined by the display form adjusting means 17 (see FIG. 1). Since they are mutually adjusted within the display range of, the appearance of the entire list is not broken and the visibility is also good.

As a result, by selecting a display method suitable for each recorded content, that is, selecting content information to be displayed in a list for each content, redundant content information can be omitted and individual content identifiability can be improved. . In addition, a display area 40 for each content in the list
