Hereinafter, the operation of the display device having the storage function according to the embodiment of the present invention will be described.

A digital broadcast signal is transmitted in the form of a packetized transport stream by time division multiplexing a video signal, an audio signal, and additional data.

The first broadcast receiving unit 10 and the second broadcast receiving unit 20 receive broadcast signals transmitted from the outside through an antenna and receive broadcast signals having a frequency band corresponding thereto according to a tuning control signal of a controller 80, A demodulator for outputting the output signal of the transport stream in the form of a video signal through a VSB (Vestigial Sideband) demodulation process and an error correction process; And a demultiplexer for separating the audio data into various additional data defined by an audio signal and Program and System Information Protocol (PSIP) information and outputting the data in bit stream form.

Signals received through the first broadcast receiver 10 and the second broadcast receiver 20 are signal processed through the first broadcast signal processor 30 and the second broadcast signal processor 40, And outputted through the signal output section 50.

The first broadcast signal processor 30 and the second broadcast signal processor 40 may include a video signal processor for processing the separated video signal and an audio signal processor for processing an audio signal, The broadcast signal output unit 50 includes a display unit for outputting the signal-processed video signal and a speaker for outputting the signal-processed audio signal.

Here, the video processing unit (not shown) includes an MPEG-2 decoder and a scaler for converting the video data to a vertical frequency, a resolution, an aspect ratio, etc. according to an output standard of a display unit (not shown).

The display unit may be applied to various types of display modules such as DLP (Digital Light Processing), LCD (Liquid Crystal Display), and PDP (Plasma Display Panel).

The audio signal processing unit (not shown) may include an AC-3 decoder.

The user interface unit 60 is a means for receiving a request command from a user. Typically, the remote controller and the local key input unit may be included in the user interface unit 60.

The storage unit 70 is a hard disk serving as a mass storage medium and stores a specific broadcast signal according to a user request among the broadcast signals received through the first broadcast receiver 10 and the second broadcast receiver 20. [

In addition, the storage unit 70 stores information on pre-registered preferred programs.

Here, in the preferred program registration method, a user may manually select a specific program and register it as a preferred program, or may select a preferred program according to the frequency of viewing by the user, and accordingly, May be registered.

The control unit 80 checks the broadcast time of the pre-registered favorite program according to the state of the preference program time shift function setting, and if the broadcast signal of the specific channel on which the preference program is broadcast is broadcasted at the broadcast time of the preference program And stored in the storage unit 70.

Here, the preference program time shift function automatically stores the preference program in the storage unit 70 and performs a time shift operation according to the preference program even if the user does not input a separate command at the time of broadcasting the pre-registered favorite program .

Accordingly, when the preference program time shift function is set to on, the controller 80 checks the broadcast time of the favorite program based on the favorite program information previously stored in the storage unit 70.

In addition, when the broadcast time of the specific preference program is reached based on the confirmed preferred program airing time, the control unit 80 confirms the viewing program that the current user is watching.

In this case, when a plurality of programs are registered as a favorite program in the same broadcast time zone at the time of confirming the broadcast time, the controller 80 controls the broadcast time of the favorite program corresponding to the first rank .

The viewing program being watched by the user means a program received through any one of the first broadcast receiving unit 10 and the second broadcast receiving unit 20 and outputted through the signal output unit 50. [

Then, the controller 80 determines whether the program currently being watched by the user is the same as the currently broadcasted favorite program. In other words, it is determined whether the channel currently being watched by the user and the channel to which the preference program is to be broadcast are the same channel.

Accordingly, when the viewing program and the preference program are not the same program, the control unit 80 controls the broadcast receiving unit not used in the background, that is, the broadcasting receiving unit for receiving the broadcasting signal of the channel currently being watched by the user The broadcast signal of the channel on which the preferred program is to be broadcasted is received and stored in the storage unit 70. [

That is, when the channel currently being watched by the user and the channel on which the preference program is broadcast are not the same channel at the start time of the broadcast of the preference program, that is, when the current user does not watch the preference program to be broadcasted, Receives the broadcast signal of the channel through which the program is broadcasted, and stores the broadcast signal in the storage unit 70.

In addition, the controller 80 periodically determines whether a channel change request command is input. When the channel change request command is input, the controller 80 determines whether the channel to be switched is the same channel as the channel in which the preferred program is broadcast .

That is, the controller 80 determines whether the reception channel of the first broadcast receiver 10 and the reception channel of the second broadcast receiver 20 coincide with each other. If the reception channel is inconsistent, A signal is selected and outputted through the broadcast signal output unit 50. When the reception channel is coincident, the control unit 50 controls the signal output unit 50 to output a notification message according to the broadcast program stored in the background in the background .

For example, if the 'Infinite Challenge' program that is broadcasted through Channel 10 is a preferred program and the user does not watch the Infinite Challenge at the start of the 'Infinite Challenge', the 'Infinite Challenge' And stored in the storage unit 70 in the background.

When the channel switching command to the channel 10 in which the 'infinite challenge' is broadcasted from the user is input after the time when the 'infinite challenge' is stored in the storage unit 70, as shown in FIG. 2 The channel information 110 of the switched channel and the storage notification message 120 of the broadcast program broadcasted on the channel are displayed on the video screen 100 100).

Accordingly, the control unit 80 determines whether the user is watching the 'Infinite Challenge' from the start point of the 'Infinite Challenge' to the end of the 'Infinite Challenge' A time shift function is provided by using the broadcast signal stored in the background with respect to the last broadcast until the point in time when the switch command is input.

That is, if the program being broadcast after the channel switching is a favorite program that the user normally likes, anyone can have a sadness and curiosity about the last broadcast from the start point of the favorite program. As shown in FIG. 3, According to the present invention, the program is automatically stored in the storage unit 70 at the start time of the broadcast of the favorite program, thereby providing a time shift function such as viewing the last broadcast of the favorite program (the part that the user has not watched) can do.

Also, the control unit 80 recognizes the time of the broadcast signal stored in the background, and automatically deletes the broadcast signal from the storage unit 80.

Here, the viewpoint is determined by a preset deletion condition from a user, and the deletion condition may be variously set according to a user request.

That is, the deletion condition may include a broadcast end time of the preference program, a time point at which a predetermined time elapses from the broadcast date of the preference program, and whether or not to view the stored preference program. And controls the automatic deletion of the stored preferred programs.

As described above, in the display device having the storage function according to the embodiment of the present invention, if the program being broadcast after the channel switching is a favorite program that the user normally enjoys, the user may feel a lack of interest in the last broadcast of the broadcast program, It is possible to improve the user satisfaction by providing a time shift function for last broadcasts that the user has not yet watched and to provide a function of storing and deleting a favorite program in the background. You can solve the inconvenience you have to choose.

As shown in FIG. 4, a control method of a display device having a storage function according to an embodiment of the present invention configured as described above first sets a preference program (S10). That is, a specific program may be selected on the broadcast program guide and registered in the preference program, or the preference program may be automatically set according to the frequency of watching the user.

Next, on / off of the preference program time shift function is set (S20). That is, it is set whether to use the automatic saving function of the preference program or not.

Then, a deletion condition of the preference program stored according to the preference program time shift function is set (S30). That is, as described above, the deletion condition of the preference program is set based on any one of the termination time of the preference program, a time point elapsed from the broadcast date of the preference program, and whether or not the preference program is watched .

In addition, as shown in FIG. 5, a control method of a display device having a storage function according to an embodiment of the present invention as described above determines whether a preference program time shift function is set up (S100).

Then, if the preference program time shift function is set to ON, the broadcast time of the pre-registered favorite program is confirmed (S110). At this time, if there are a plurality of preference programs broadcasted at the same time, the broadcast time of the favorite program corresponding to the first rank is confirmed according to the predetermined priority.

Then, it is determined whether the current time is the start time of the broadcast of the favorite program (S120).

If it is determined at step S120 that the current time is the start time of the broadcast of the favorite program, the viewing program currently being watched by the user is checked at step S140.

Then, it is determined whether the confirmed viewing program and the preference program to be broadcast are the same program (S150). That is, it is determined whether the current user is viewing a channel through which the preference program is to be broadcasted.

If it is determined in step S150 that the viewing program and the preference program are different, the broadcast signal of the channel to be broadcasted in the background is received and stored in step S150.

Then, it is determined whether a channel switching command is input from the user (S160).

If the channel switching command is inputted from the user (S160), it is determined whether the channel to be switched and the broadcasting channel of the preferred program are the same channel (S170).

If it is determined in step S170 that the channel to be switched is different from the channel being broadcasted by the preferred program, the user performs a switch to a channel to be switched in step S180.

If it is determined in step S170 that the channel to be switched and the channel being broadcast by the preferred program are the same channel, the switching to the channel to be switched and the notification of the storage of the corresponding preferred program A message is displayed. Then, in response to the user's request, the user performs a time shift operation such as returning to the last broadcast of the favorite program using the stored data of the preference program stored in the background (S190).

In addition, as shown in FIG. 6, a control method of a display device having a storage function according to an embodiment of the present invention configured as described above first confirms a pre-stored favorite program (S200). That is, it confirms whether there is a pre-stored favorite program.

Then, the deletion condition of the confirmed preferred program is confirmed (S210).

Then, it is determined whether the present time is the time to delete the preferred program based on the checked deletion condition (S220).

If the current time is the deletion time point of the preferred program (S220), the pre-stored favorite program is deleted (S230).

As described above, in the method of controlling the display device having the storage function according to the embodiment of the present invention, if the broadcast program is a favorite program that the user normally enjoys after switching the channel, It is possible to improve user satisfaction by providing a time shift function for last broadcasts that the user has not yet watched and to provide a function of storing and deleting a favorite program in the background, It is possible to solve the inconvenience of selecting the delete operation.
