The present invention relates to a method for reproducing a recording in a digital broadcast receiver which searches for contents of the recording using a thumbnail image and reproduces the contents at a desired position.

Recently, the terrestrial receiver has become more complicated and various products are released according to the trend of widespread and advanced. One of the hottest topics in recent years is the DVR (Digital Video Recorder).

A DVR is a personal digital video recording device that records and plays back information on a hard disk. Unlike a VCR that stores video signals on a magnetic tape, a DVR is a new concept of digital recording device that records and plays back information on a hard disk. It is a next-generation recording device that can record a certain amount of broadcast programs according to its capacity without using a VCR through the hard disk drive built into the set-top box and the TV main body.

When the DVR selects a channel, the currently broadcast signal on the hard drive is automatically stored digitally and played simultaneously. Therefore, if you press the play button and then press the play button again, the stored broadcast signal is played again from the point where it stopped. You can also view the currently sent program, play it back in slow motion, and jump over boring parts, making it easy to find and edit the parts you want.

However, in order to search for contents while watching a recording of the related art, it is inconvenient to sequentially search through the fast forward, backward, and play functions such as a video cassette record.

In addition, since the overall contents of the recording cannot be viewed, there is an inconvenience in that the user has to wait until the contents are played to find the desired portion.

Accordingly, an object of the present invention is to provide a method for reproducing a recording in a digital broadcast receiver, which can search for an approximate content of a recording in a digital broadcast receiver and reproduce the content at a desired location.

According to an aspect of the present invention to achieve the above object, in a method for playing a recording in a digital broadcast receiver equipped with a storage medium, there is a program that receives and stores the recording configuration information from the user, the recording time When the program is recorded, a thumbnail image is extracted and stored at a thumbnail image extraction time interval in the recording environment setting information. When a recording list request command is input, a recording list stored in the storage medium is displayed, and the displayed recording is displayed. When one list is selected from the list, a multi-screen is provided in which a thumbnail image corresponding to the list is provided, and when a thumbnail image is selected through the multi-screen, the main screen is played from the position of the selected thumbnail image. From digital broadcast receiver Provided is a method for reproducing a recording.

The recording environment setting information includes thumbnail image extraction time intervals and the number of thumbnail images to be output per page.

If there is a program that has reached the recording time, extracting and storing the thumbnail image at the thumbnail image extraction time interval in the recording environment setting information while recording the program includes a program whose recording time has been reached by a recording command or a scheduled recording command. If there is a program that has a recording time as a result of the determination, it refers to extracting a thumbnail image from the corresponding broadcast signal at the thumbnail image extraction time interval, and mapping and storing the extracted thumbnail image and its location information.

In the displaying of the thumbnail image on a multi-screen, the multi-screen displays a program name, a main screen, a sub-screen provided with one or more thumbnail images stored when recording the program, and a progressive bar.

The multi-screen may be in the form of a PPO.

When the thumbnail image is selected through the multi-screen, reproducing from the position of the selected thumbnail image on the main screen selects a desired thumbnail image using the sub-screen or progressive bar, and confirms location information mapped to the selected thumbnail image. To play from the position on the main screen.

Referring to FIG. 2, the digital broadcast receiver stores recording environment setting information input by a user (S200). The recording environment setting information includes a thumbnail image extraction time interval when recording a program, and the total number of thumbnail images to be displayed on one page when searching for recordings. The recording environment setting information is information set when the user wants to extract a thumbnail image.

Therefore, the user selects the recording environment setting menu using the menu key. Then, the digital broadcast receiver displays a screen for setting a recording environment as shown in FIG.

Referring to FIG. 3, a recording environment setting screen includes an area for inputting / selecting a thumbnail image extraction time interval and the number of thumbnail images to be output per page. The user inputs / selects a thumbnail image at a desired time, for example, at a 5-minute interval, in the 'thumbnail image extraction time interval' column.

In addition, the user inputs / selects the number of thumbnail images to be output on one page, for example, five in the 'number of thumbnail images to be output per page' field. The input / selected thumbnail image is output to a predetermined area of the playback screen.

Then, the digital broadcast receiver stores the recording environment setting information input by the user.

After the execution of step 200, if there is a program that has a recording time by a recording command or a scheduled recording command (S202), the digital broadcasting receiver records a thumbnail at intervals of extracting thumbnail images of the stored recording configuration information while recording the corresponding program. The image is extracted and stored (S204). In this case, the stored thumbnail image is mapped and stored together with the location information of the thumbnail image.

That is, the digital broadcasting receiver stores a corresponding program in a storage medium, and separately configures a database by mapping the extracted thumbnail image and its location information at predetermined time intervals separately. For example, if a thumbnail image extraction time interval is '5 minute interval', the digital broadcasting receiver extracts a thumbnail image at 5 minute intervals immediately after recording of the corresponding program and maps and stores the thumbnail image.

After performing step 204, if a recording list request command is input by the user (S206), the digital broadcast receiver displays the recording list stored in the storage medium (S208).

That is, when the user inputs a recording list request command using a menu key or a hot key, the digital broadcasting receiver displays a recording list providing screen as shown in FIG. 4A or 4B.

Referring to FIG. 4A, a recording list providing screen displays a representative thumbnail image of each recorded program, a program name thereof, a recording time, and the like. The user can view the displayed recording list and select a desired recording list.

Display. The sub-screen may be in the form of POP.

For example, if the user sets the number of thumbnail images to be output per page to five, the digital broadcasting receiver outputs five thumbnail images in chronological order for the corresponding program.

Referring to FIG. 5 with respect to the multiple screen outputting the thumbnail image, the multiscreen 500 outputting the thumbnail image includes a program name, a main screen 510, a subscreen 520 provided with a thumbnail image, and a progressive bar ( progressive bar 530 is indicated. The main screen 510 plays a current program or a thumbnail image selected on the sub screen 520.

The sub-screen 520 outputs as many thumbnail images as the number of thumbnail images to be output per page in the recording configuration information. That is, scenes 5 to 10 of the sub-screen 520 are thumbnail images for each section set in the recording.

Accordingly, the user may scroll through the thumbnail image output on the sub-screen 520 using the direction keys to search the entire contents of the recording.

The progressive bar 530 represents the total length of the recorded program, and the selection box displayed on the progressive bar 530 shows the position of the designated thumbnail image compared to the total length of the recording.

Accordingly, the user may vertically scroll the thumbnail image and the progressive bar 530 to simultaneously search the entire contents of the recording.

The progressive bar 530 is mapped to the position of the thumbnail image and points to a position that matches the position of the thumbnail image. Accordingly, when the user moves the selection box of the progressive bar 530 by using the direction key of the remote controller, the thumbnail image corresponding to the selection box is selected, and the main screen 510 uses position information of the selected thumbnail image. The recording is played.

In addition, when the user selects a desired thumbnail image on the sub-screen 520, a position corresponding to the selected thumbnail image is displayed on the progressive bar 530, and the main screen 510 displays a position of the selected thumbnail image. The recording is played using the information.

As described above, when a user selects a desired thumbnail image using the thumbnail image or the progressive bar 530, the digital broadcasting receiver plays the corresponding recording on the main screen 510 using the location information of the selected thumbnail image. .

When the desired thumbnail image is selected through the multi-screen displayed in step 212 (S214), the digital broadcast receiver reproduces the recording from the location using the location information of the selected thumbnail image on the main screen (S216).

That is, since the thumbnail image is mapped and stored according to the location information, when the user selects the desired thumbnail image, the digital broadcasting receiver searches a database to determine the location information mapped to the selected thumbnail image. The digital broadcast receiver then plays back from the determined position on the main screen and displays the position on the progressive bar.

If a multi-screen release command is input by the user during step 216 (S218), the digital broadcast receiver releases the POP-type multi-screen so that only the main screen is displayed (S220). That is, if the user wants to release the POP-type multiple screen, the user selects the EXIT key existing in the remote controller. Then, the digital broadcast receiver recognizes the selected EXIT key as a multi-screen release command to release the sub-screen so that only the main screen is displayed.

As described above, the user can simultaneously search the entire contents of the recording by using the thumbnail image and the progressive bar provided on the thumbnail image providing screen, and play them at a desired position.

The present invention is not limited to the above embodiments, and many variations are possible by those skilled in the art within the spirit of the present invention.

As described above, according to the present invention, it is possible to provide a method for reproducing a recording in a digital broadcasting receiver which can search for an approximate content of a recording in a digital broadcasting receiver and play the recording at a desired position of a user.
