The present invention relates to a backup apparatus and method, and more particularly, to a backup apparatus and method of a recording system.

With the development of Digital TeleVision (DTV) technology, users have experienced the superiority of HD (High Definition) video and Dolby Digital voice, and continued development of compression algorithms and high performance of hardware. The better environment was encountered.

One of the advancements in this technology is the Personal Video Recorder (PVR). The PVR refers to a personal digital video recording device for recording and playing back information on a hard disk.

PVR, unlike VCR (Video Cassette Recorder) which stores video signal on magnetic tape, is a new concept of digital recording device that records and plays back information on hard disk. It is a recording device that can record a certain amount of broadcast programs according to its capacity without a VCR through a hard disk drive built into a set-top box or a television body.

Its basic function is not much different from the existing VCR in that it saves and views the program exported from the broadcasting station, but it records the information on the hard disk and plays it with a file playback method such as a computer, and the central processing unit and operating system for playback. The difference is that a memory chip containing software and a large capacity hard disk are included.

The PVR saves and records the currently broadcast program on the hard disk so that the screen missed during TV viewing can be viewed again. Even if you leave your seat for a while, you can watch continuously from the previously watched screen. This is called a time shift function.

In addition, a variety of information about the program can be viewed using the program guide (EPG), and recording reservation can be easily performed using the broadcast guide or channel and time information.

And you can schedule program viewing according to your personal choices and tastes, giving viewers more control over television. That is, viewers can see the program they want to see when they want to see it, regardless of the program schedules prepared by the broadcasters.

However, since the capacity of the hard disk included in the PVR is limited, important broadcast programs or broadcast programs having a storage value can be backed up to an external storage device and stored.

However, in the case of the backup process, since the data is stored in an external storage device in real time, there is a problem that another hard disk related operation such as time shift cannot be performed while the backup is in progress.

In addition, when the automatic deletion function is set for the recorded broadcast program, there is a problem that the important broadcast program cannot be backed up and deleted.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to provide a backup backup device and method that can schedule a backup time, etc., to automatically back up without disturbing other functions due to backup To make it possible.

Features of the backup device according to the present invention for solving the above problems, the receiving unit for receiving broadcast data, the storage unit for storing the received broadcast data, the user interface unit for receiving the reservation information for the backup, and the user interface And a control unit for receiving backup reservation information from the unit, and controlling to read the broadcast data stored in the storage unit and back it up to an external storage device according to the reservation information.

According to an aspect of the present invention, there is provided a backup method including displaying a list of stored broadcast data, receiving backup reservation information of selected broadcast data from the list, and reading the selected broadcast data according to the input backup reservation information. Backing up to an external storage device.

1 is a block diagram illustrating a configuration of a personal video recorder (PVR) including a backup device according to an embodiment of the present invention.

The PVR includes a user interface 110, a controller 120, an HDD 130, an A / V signal processor 140, an OSD unit 150, and a display 160.

The broadcast program received through a tuner (not shown) or the like is displayed on the display unit 160 through A / V signal processing. In this case, when a storage command for storing the broadcast program received using the PVR function is input or when reserved storage is executed, the received broadcast program is stored in a hard disk drive (HDD) 130. The HDD may store not only a general TV broadcast program but also all digital broadcast programs such as data broadcast, and in the case of analog broadcast, may be converted into a digital broadcast format and stored.

The broadcast programs stored in the HDD 130 are arranged in a list and provided to the user. The user may select and view the stored broadcast program again and manage the stored broadcast through various management menus.

When playing the stored broadcast program, the user selects the stored broadcast program through the user interface 110 and inputs a command such as playback. When the command is input, the A / V signal processor 140 performs audio / video signal processing by reading data of a broadcast program stored in the HDD 130.

The audio / video data processed by the A / V signal processor 140 is displayed to the user through the display 160. The controller 120 controls the playback process.

When the stored broadcast program is to be backed up to an external storage device, the user selects the stored broadcast program through the user interface 110 and inputs a backup command.

When the command is input, data of a broadcast program stored in the HDD 130 is read, transmitted to the external storage device 170, and stored. The controller 120 controls the backup process. The external storage device for the backup may be any storage medium that can be connected and compatible from the outside.

2 is a diagram illustrating a broadcast program list, broadcast program information, and a menu for a selected broadcast program stored in the HDD according to an embodiment of the present invention.

Broadcast programs stored in the HDD are provided on the screen as a recording list, and basic information about each recorded broadcast program is provided. In the recording list, a user can select a desired broadcast program to play, delete, or change a title through a menu.

The backup command is one of the menus for managing stored program data. The user selects a copy menu to an external storage device through the menu screen and inputs a backup command.

When the user command is input through the user interface unit 110, the controller 120 displays an OSD as shown in FIG. 3 on the OSD (On Screen Display) unit 150 asking whether to start backup to an external storage device. To be processed and displayed.

3 is a diagram illustrating a menu asking whether to start a backup to an external storage device and whether to make a reservation according to an embodiment of the present invention.

If 'Yes' is selected from the menu, the selected program data is immediately transmitted to the external storage device and the backup starts. If the user selects 'No', the backup command is canceled and the menu moves to the upper menu.

If the 'reservation setting' is selected from the menu, a menu for setting a time for backing up the selected broadcast program to an external storage device is displayed on the screen.

4A is a diagram illustrating a menu for setting a backup reservation time to an external storage device according to an embodiment of the present invention.

When the user selects 'reservation setting' from the menu as shown in FIG. 3, a menu for setting a backup reservation time is displayed on the screen as shown in FIG. 4A. The user may set a backup date and a backup time as shown in the menu of FIG. 4A.

The user may set the time such as the dawn time when the TV is not watched, the absent time, etc. in order not to disturb the function of the PVR.

4B is a diagram illustrating another menu for setting a backup reservation time to an external storage device according to an embodiment of the present invention.

The user may set a storage period for the stored broadcast program based on the number of times or the time. For example, the storage period may be set to 'once', 'one week', 'monthly', 'permanent preservation', or the like.

If 'once' is selected and set among the storage periods, the stored broadcast program is automatically deleted after being played once. If one month is selected and set among the storage periods, the stored broadcast program is automatically deleted one month after the stored time.

When the storage period is set as described above, the stored broadcast program may be automatically deleted without being recognized by the user. Therefore, the backup time of the broadcast program having the storage period can be set using the backup schedule time setting menu as shown in FIG. 4B.

As shown in the menu of FIG. 4B, the backup reservation time may be set based on a time or a play count.

For example, if the backup schedule time is set to 3 days before the automatic deletion, the backup will be automatically performed 3 days before the automatic deletion due to the expiration of the storage period. It automatically backs up three times before the automatic deletion due to the expired number of playbacks.

That is, the former automatically backs up three days before the storage period expires, and the latter automatically backs up when three times the number of times of play remain.

The backup reservation time setting menu of FIGS. 4A and 4B may be included in one reservation setting menu screen and provided to the user. As shown in the drawing, the user selects the backup reservation time setting menu according to whether to set a storage period of a broadcast program. The setting menu screen may be separately provided.

5 is a flowchart illustrating a procedure of setting a backup schedule time and backup of an external storage device according to an embodiment of the present invention.

A list of broadcast programs stored in the HDD is displayed on the screen at the request of the user. A user selects a backup program and a backup command from the stored broadcast program list (S510).

When the backup command is input, a menu asking whether to back up to an external storage device as shown in FIG. 3 is displayed on the screen, and it is determined whether the user inputs a backup reservation setting command (S520).

If the user selects 'No' from the menu as shown in FIG. 3, the user cancels the backup command, and if the user selects 'Yes', the user directly backs up the selected broadcast program to the external storage device (S550).

When the user selects 'reservation setting' from the menu as shown in FIG. 3, the backup reservation time setting menu as shown in FIGS. 4A and 4B is displayed. The user may set a scheduled time to be backed up using the setting menu (S530).

The backup schedule time may be simply set as a date and time, or when the storage period of the broadcast program is set, the storage period may be set based on the remaining days or the number of times of playing.

When the backup schedule time is set, it is determined whether the backup schedule time set by the user has been reached using a timer or the like (S540).

If it is determined in step S540 that the backup reservation time has not been reached, the device waits until the reservation time is reached. When the backup scheduled time is reached, the stored program data is transmitted to the external storage device according to the set contents to back up the data (S550).

It is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.

As described above, according to the backup device and method of the present invention, it is possible to provide a convenience by allowing a user to set a backup scheduled time.

The user can set a backup schedule time, such as a time when the HDD-related operation is not performed, and there is an effect that the progress of other functions due to the backup can not be interrupted. In addition, when a backup schedule time or the like is set based on the storage period of the broadcast program, an important broadcast program or the like can be backed up before being automatically deleted.
