The present invention relates to a method of providing content information of a digital recording system, and more particularly, to a method of providing content detailed information having high identification of content and making it easy to input or modify a content name.

As is well known, digital broadcasting refers to television broadcasting which compresses and outputs a television signal into a digital form in which an information signal is encoded and recorded. Conventional analogue television broadcasting can only carry one image in one radio wave, and voice has to be transmitted in another radio wave. On the other hand, since digital broadcasting can carry a plurality of images or audios in one radio wave and can compress information without degrading the quality, 4 to 8 channels can be set in the frequency band of the conventional analog broadcasting channel. . In addition, it is easy to control information using a computer, and it is also possible to interactively export information ordered from the viewer side. Digital broadcasting compresses video and audio, and modulates multiple signals. Communications and computers also use these compression and multimodulation techniques. Therefore, digital broadcasting is a core technology of the multimedia age where broadcasting, communication, and computer are combined.

Recently, with the rapid development of such digital broadcasting technology, a personal video recorder (PVR), which uses a storage device such as a hard disk driver (HDD) as an image storage medium by integrating with computer technology, has been in the spotlight. . The PVR is a personal video storage device that can digitally store the received broadcast signal in the HDD instead of the existing video tape.

Such a PVR can digitally record broadcasts such as over-the-air TVs, cable TVs, and satellites. If a pause command is input during broadcast playback, the PVR can record until a play command is input. Therefore, even after a predetermined time elapses after the user presses the pause button, the user can view a broadcast from the time when the user presses the pause button. At this time, the broadcast signal from when the pause command is input to when the playback command is input is stored in a storage device such as a hard disk driver (HDD).

1 illustrates a block diagram of a PVR as an example of a general digital broadcast receiver.

As shown in FIG. 1, the PVR includes a receiver 11, a decoder 13, a codec 15, a D / A converter 17, a controller 19, a storage 21, and an input 23. ), An EPG processing unit 25 and a list information generating unit 27.

The decoder 13 converts a digital broadcast signal received through the receiver 11 from the outside into a signal that can be viewed or stored. When the broadcast signal received from the outside is a CVBS (Composite Video Signal) signal, the decoder 13 converts the CVBS signal into a YUV signal or an RGB signal.

When a recording command for a broadcast signal is input through the input unit 23, the decoder 13 converts an analog signal CVBS signal into a digital signal YUV signal and outputs it.

The codec unit 15 encodes, ie, compresses, the input YUV signal and outputs the MPEG data. The compressed MPEG data is stored in the storage unit 21. The storage unit 21 uses a mass storage medium such as an HDD.

When a playback command for the MPEG data stored in the storage unit 21 is input, the codec unit 15 detects the stored MPEG data from the storage unit 21. The codec unit 15 decompresses the detected MPEG data and outputs the compressed YUV signal. That is, the compression codec unit 15 compresses and encodes the YUV signal under the control of the control unit 19, or compresses and decodes the compression-encoded signal.

The D / A converter 17 converts the decompressed YUV signal into an RGB signal which is an analog signal. On the other hand, when there is no storage command for the received broadcast signal from the input unit 23, the decoder 13 converts the CVBS signal into an RGB signal and outputs it.

The RGB signal converted by the decoder 13 or the D / A converter 17 is input to an image display unit (not shown) to implement an image.

The controller 19 controls the decoder 13 to convert the received broadcast signal into a digital signal when a storage command for the broadcast signal is input from the input unit 23. In addition, when a reproduction command for the stored compressed data is input, the controller 19 controls the codec unit 15 to detect and decompress the stored compressed data.

The digital broadcast signal received through the receiver 11 includes not only audio and video packets but also a program and system information protocol (PSIP), so that the information on the program of each channel can be known. That is, the packetized audio and video information is configured so that the contents can be viewed only when the PSIP information is present. The PSIP information includes EIT (Event Information Table) information, which is commonly called a broadcast guide.

The decoding unit 13 extracts the EIT table included in the digital broadcast signal under the control of the control unit 19, and the program ID (PID), start time, broadcast time length, program grade, It decodes and outputs information such as video type and audio multiplex.

The EPG processor 25 constructs a broadcast guide screen, that is, an EPG screen, in a unique format and displays the broadcast guide information decoded by the decoder 13 on the display device.

When the broadcast program is stored in the storage unit 21, the list information generation unit 27 generates list information including a content name, a recording time, a thumbnail, and the like of a broadcast program, and input unit 23. List information generated by the request is displayed on the display device.

Referring to FIG. 2, when an arbitrary broadcast program, that is, content is stored in the storage unit 21, the list information generation unit 27 enters a list information generation mode (S52), and the list of contents currently received for storage is stored. The channel number or program title is extracted (S54), and the extracted information is stored as a content name (S56).

The content name and list information stored in step S56 are output to the list information screen when a request is made to be provided through the input unit 23.

However, the content name provided by the list information generation unit 27 is insufficient to indicate the content of the content stored in the storage unit 21 and the like. This is because the channel number or program title of the broadcast program is extracted and used mostly as the content name when determining the content name.

Therefore, the user may change the content name using the input unit 23 while the list information screen is displayed by the list information generation unit 27.

When inputting the key assigned for editing the content name through the input unit 23 is provided a character input window through the screen (S60), if the user completes the edit after changing the content name using the text input window (S62) The modification of the content name is completed (S64).

However, according to the prior art, it was not sufficient to grasp the contents of the contents based on the list information, and the identification of the contents could be somewhat improved by editing the contents name, but it was difficult to edit because the input should be made directly through the text input window. There was this.

The present invention has been proposed in order to solve such a conventional problem, and has an object of having a high identification of content by automatically generating a content name based on EPG broadcast information.

Another object of the present invention is to make it easy to edit the content name by copying the text from the EPG broadcast information and using the copied text as the content name.

Still another object of the present invention is to include a plurality of thumbnails in generating content detail information, so that individual thumbnails can be deleted or added to further double the identification of the content.

The content information providing method of the digital recording system according to the present invention for achieving the above object is a content information providing method for providing content list information in the digital recording system, the method comprising the steps of extracting the EPG broadcast information, the content information; Providing a selection screen to determine whether to include in the content name basic information including at least one of a channel number or a program title of the corresponding content to be provided; and including the basic information through the selection screen is selected. Generating the content name based on a preset text section among basic information and EPG broadcast information; and if the inclusion of the basic information is not selected through the selection screen, the content name is based on the preset text section among EPG broadcast information. Generating.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In addition, in describing the present invention, when it is determined that the detailed description of the related known configuration or function may obscure the gist of the present invention, the detailed description thereof will be omitted.

The content information providing method according to the present invention illustrated in FIGS. 3 and 4 may be executed in a PVR, which is an example of the general digital recording system illustrated in FIG. 1.

3 and 4, the method for providing content information according to the present invention includes extracting EPG broadcast information in a content name generation mode (S102 to S104), a channel number or a program of corresponding content to provide content information. Providing a selection screen to determine whether to include the basic information including at least one of the title in the content name (S106), and if the inclusion of the basic information through the selection screen from among the basic information and EPG broadcast information Generating the content name based on the preset text section (S108, S110, S112); and if the inclusion of the basic information is not selected through the selection screen, generating the content name based on the preset text section among the EPG broadcast information. Steps S108 and S114, and providing a text input window when editing of the generated content name is requested (S116 to S118), and a text input window. When the editing of the content name is completed through the step of modifying the content name according to the edit result (S120 ~ S122), and extracting a plurality of thumbnails in a predetermined number of times at a predetermined time interval from the content to generate the content details information Steps S202 to S212 are included.

A content name generation process and a content detail information generation process by the content information providing method of the digital recording system according to the present invention configured as described above will be described in more detail with reference to FIGS. 1, 3, and 4.

First, when any broadcast program, that is, content is stored in the storage unit 21, the list information generation unit 27 enters the content name generation mode (S102), and is received from the EPG processing unit 25 for the current storage. EPG broadcast information on the content is provided (S104).

In addition, the list information generation unit 27 displays a basic information selection screen for selecting basic information of content to be stored, that is, corresponding information for determining whether to include a channel number and / or a program title in the content name. Provided through the device (S106).

According to the user's selection on the basic information selection screen, the list information generating unit 27 extracts the basic information and, if inclusion of the basic information is selected, generates and stores the content name based on the basic information and the EPG broadcasting information. (S108, S110, S112) If the inclusion of the basic information is selected, the content name is generated and stored with reference to only EPG broadcast information (S108, S114).

At this time, in the application of the EPG broadcast information to the content name, a certain section of the EPG broadcast information is applied as the content name according to a preset state. Here, it may be desirable to apply the first line of EPG broadcast information as the content name.

Here, when the user selects the content name editing menu through the input unit 23 (S116), a text input window is provided through the screen (S118), and the user completes the edit after changing the content name using the text input window. In operation S120, the content name is corrected in operation S122.

Such a content name editing process according to the present invention is processed in the same manner as the prior art described with reference to FIG. Without modifying only a part according to the user's taste it is possible to modify the content name much more convenient than the prior art. In addition, even if the EPG broadcast information of the corresponding content is not copied by copying the text of the EPG broadcast information of the similar content can be used as the content name, thereby improving the ease of editing the content name.

When the content name generation process is completed, content list information is provided when a user's request is generated through the input unit 23. When a user selects specific content on the content list information screen and requests detailed information, Detailed information including a thumbnail of the corresponding content is provided. To this end, when the content name generation process according to FIG. 3 ends, the content list generation mode is immediately entered to complete the content list information.

Referring to FIG. 4, in the content detail information generation mode (S202), the list information generator 27 receives broadcast information such as a recording time and a genre of the corresponding content from the EPG processor 25 (S204). A plurality of thumbnails are extracted and stored as many as a preset number at predetermined time intervals (S206).

Here, when the user requests a change of the thumbnail through the input unit 23 (S208), the list information generation unit 27 provides a menu screen for changing the thumbnail through the display device, and the user himself or herself through the thumbnail change screen. As desired, thumbnails can be deleted or added (S210). The thumbnail deletion procedure deletes the thumbnail by pressing the delete key when the thumbnail that you want to delete is displayed among the thumbnails displayed in the loop.In the thumbnail addition procedure, when a thumbnail addition key is pressed, a search screen for the corresponding content is provided. The user may add a still image as a thumbnail while playing or fast playing the content through the content search screen.

The content detail information thus obtained is stored by the list information generation unit 27. When the user requests the output of the content detail information through the input unit 23, the corresponding content detail information is displayed on the display device to display the content. The identification for the doubled (S212).

The above description is merely illustrative of the present invention, and it is obvious that the techniques of the present invention can be easily modified and implemented by those skilled in the art. Such modified embodiments should be construed as naturally included in the technical spirit described in the claims of the present invention.
