Technical Field [0001] The present invention relates to an image display apparatus,

This embodiment relates to a video display device and a video display method, and relates to a reserved recording of a series.

As is well known, a digital broadcast receiver such as a set top box receives a digital TV broadcast, restores a digital broadcast signal of an MPEG transport stream into an original video / audio signal, It is transmitted to a TV or a separate monitor so that a user can watch a broadcast program of a desired broadcast channel.

A hard disk drive of a large capacity is employed to receive a broadcast program of a specific channel, record it, and reproduce and output the broadcast program at a desired time by a user.

On the other hand, TV broadcasting programs are diversified into drama, movies, entertainment programs, documentary programs, etc. in consideration of the viewer's taste. Each broadcasting program stably maintains viewer ratings of viewers, And the tendency to broadcast is strongly displayed.

However, in order to record a series of broadcast programs of TV broadcasts, it is necessary for the viewer to manually perform the recording operation by manual operation in accordance with each broadcast time, so that a considerable inconvenience is added to viewers, If it does not match properly, continuous recording of a complete series becomes difficult.

The present embodiment described in the following description enables a schedule recording of a series of programs to be performed more easily, and a schedule recording list is displayed by simply highlighting a calendar outputted to the OSD by a corresponding date, So that the user can obtain the reserved recording information.

The video display device of this embodiment includes a tuner for receiving a broadcast signal; A demodulator for demodulating the selected channel through the tuner; A demultiplexer for demultiplexing the demodulated signal into audio, video and PSIP tables; A decoder for decoding the demultiplexed video signal; A microcomputer controlling the EPG information extracted from the demultiplexed data to be output to an OSD (On Screen Display) and controlling the scheduled recording of the series to be performed using the EPG information; A storage means for storing a reserved recording list of a series set by a user under the control of the microcomputer; An OSD controller for outputting a schedule recording display calendar showing information on a scheduled recording setting date of the series to the OSD under the control of the microcomputer; And a display unit for outputting the decoded video and the OSD.

In addition, a method of controlling an image display apparatus according to an embodiment of the present invention is a video display apparatus capable of scheduled recording of a series, comprising the steps of: storing a schedule of a series of events to be stored in a storage unit when a preset recording setting process of the series is performed by a user; Comparing the broadcast schedule of the series with the scheduled recording to the received EPG information; Updating a broadcasting schedule of the series stored in the storage means if the broadcasting schedule of the series included in the received EPG information is different from the pre-stored broadcasting schedule as a result of the comparison; And the modified schedule of the series is reflected in a scheduled recording display calendar that is displayed such that the scheduled recording of the series is distinguished for the set date.

According to the proposed embodiments, the user can more conveniently perform the scheduled recording of the series, and even if the schedule of the scheduled recorded series is changed, the user can more conveniently check the schedule.

Hereinafter, the present embodiment will be described in detail with reference to the accompanying drawings. It should be understood, however, that the scope of the present invention encompassed by the present embodiment also encompasses embodiments that can be readily devised through changes in design, additions and deletions of components, and the like from the disclosed embodiments.

In the following description, the word 'comprising' does not exclude the presence of other elements or steps than those listed.

First, FIG. 1 is a block diagram for explaining a video display device of this embodiment.

Referring to FIG. 1, an image display apparatus according to an exemplary embodiment of the present invention includes a tuner 10 for receiving a broadcast signal and tuning and outputting a signal of a specific channel selected by the user, A demultiplexer 30 for demultiplexing the demodulated signal into audio, video, DVB-SI, and PSIP tables, a demultiplexer 30 for demodulating the demultiplexed signal, An audio / video decoder 40 is included.

The audio / video decoder 40 includes an audio decoder for decoding and outputting an audio signal among the demultiplexed signals, and a video decoder for decoding and outputting the video signal.

A PSI / PSIP decoder 80 for decoding the PSI table or the PSIP table and an SI / PSIP database 81 for storing the decoded result are included.

The microcomputer 60 controls the series recording of a broadcast program to be performed using the EPG information included in the demultiplexed data of the PSIP table. The channel manager and the channel manager for not- And a channel database for storing information of the channel information.

The storage unit 90 may further include a storage unit 90 for storing a series of broadcast programs under the control of the microcomputer 60. The storage unit 90 may be implemented as a hard disk drive (HDD).

The microcomputer 60 controls the OSD controller 100 to output an OSD (On Screen Display) for recording a series of programs and an OSD for displaying a scheduled recording list.

In particular, the OSD generated by the OSD controller 100 includes a user interface for scheduled recording of a series and a user interface for a reserved recording list of the series. Particularly, the display of the reserved recording list of the series includes a corresponding The date is highlighted. Meanwhile, the list of reserved recordings set by the user may be stored in the storage unit 90 or may be stored in a separate storage unit.

Such a user interface will be described later with reference to the accompanying drawings.

The display unit 50 outputs the OSD along with the decoded video signal.

On the other hand, in the video display device having the above configuration, the reserved recording of the series using the received PSIP will be described.

2 is a diagram showing an example of broadcast program information.

Each broadcast program information carried by the PSIP includes channel information, a PID (Packet Identification) which is an identifier of a transport packet (TP) carrying the broadcast program, a series / program identification number, a title of a series / program, Start time, and end time.

If the broadcast program is a series, information on the current number of broadcasts, the total number of broadcasts, the broadcast program capacity information, and the broadcast / rebroadcast identification code may be further included. Information on the obtained broadcast program as shown in FIG. 2 may be stored in the storage unit 90 by the microcomputer 60, and may be referred to when necessary.

The broadcast program capacity information indicates a data size for the broadcast program, and the broadcast / rebroadcast identification board is information indicating whether the broadcast / rebroadcast identification board is broadcast or rebroadcast, It is used to prevent the program from being duplicated by being rebroadcasted.

3 is a flowchart showing a method for performing series water-recording by the video display device of the present embodiment.

When the user requests the series recording (S101), the requested series identification number (SID) is retrieved from the broadcast program information of FIG. 2 stored in the storage unit 90 (S102). When the identification number of the series to be recorded is detected (S103), the broadcast time zone (start time and end time) of the detected broadcast program is confirmed.

If necessary, for example, in the power saving mode or when the user turns off the power, the operation power is turned off until the start time of the broadcast program, and the operation power is turned on before a proper time of the start time.

On the other hand, the microcomputer 60 tunes the tuner 10 to a corresponding channel based on the broadcast time included in the broadcast program information stored in the storage unit 90 and the broadcast / rebroadcast identification information, It is confirmed whether the broadcast is broadcast or not (S104).

Then, it is determined whether the transport packet having the PID of the broadcast program of the selected series is detected by the demultiplexer 30 (S105).

If the broadcast / rebroadcast identification information indicates 'rebroadcast', the channel tuning and the PID scan operation are not performed and the recording operation is not performed.

On the other hand, without using the 'broadcast / rebroadcast identification information', 'the current number of times of broadcasting' for the broadcast program of the recorded series is stored and the 'current number of times of broadcasting' of the broadcast program of the next detected series is compared It is also possible to decide whether or not to record. That is, if they are the same, the recorded program is broadcast again so that the recording is not performed.

If it is determined that the transport packet having the corresponding PID is detected, the storage unit 90 records the series of broadcast programs in the corresponding order (S106). At this time, the program recording may be recorded in the storage means 90 in the form of a transport packet received without being demuxed or decoded. In the subsequent jamming, the demultiplexer 30 and the decoder 40 are short- / V signal.

After the recording of the broadcast programs belonging to the series, the microcomputer 60 records the broadcast programs of the series recorded in the storage unit 90 in the last series sequence (S107).

As a result of the determination, if the broadcast program recorded in the storage unit 90 is not the last series sequence, the above-described steps are repeatedly performed, and the recording operation for the broadcast program of the series is automatically performed.

On the other hand, if it is determined that the broadcast program of the recorded series is the last series, the recording mode of the series is terminated (S108).

When the recording mode is terminated, the title of the series and the number of recorded times are recorded in the storage unit 90. When the user requests the recorded program, the OSD controller 100 displays the recorded information on the screen Thereby displaying information about the recorded series.

Hereinafter, a method of displaying a recording list of a series reserved by a user to a user will be described. Then, a process of scheduling a series using an OSD output by a microcomputer of the present embodiment is described as a user interface Let's take a closer look.

FIG. 4 shows an example of an OSD displayed to a user for scheduled recording of a program according to the embodiment of the present invention, and FIGS. 5 to 8 illustrate a schedule recording of a program using the OSD according to the present embodiment. admit.

Referring to FIG. 4, when a user inputs a scheduled recording command, the OSD is displayed on the screen as a user interface for scheduled recording of a series.

The OSD 400 is provided with a scheduled recording display calendar 401 in which the date on which the scheduled recording is set is highlighted and a scheduled recording setting calendar 401 provided to allow the user to more easily select a date for setting the scheduled recording, (402).

The background image of the OSD 400 displays a video 410 of the currently broadcast program.

The dates displayed on the reserved recording display calendar 401 and the reserved recording setting calendar 402 may be displayed from the date after the current time, and the dates corresponding to three weeks or one month from the current date may be displayed.

In detail, through the reserved recording display calendar 401, the date on which the corresponding program set by the user is scheduled to be displayed is highlighted, and in order to more easily distinguish between the date on which the scheduled recording is set and the date on which the scheduled recording is set Other implementations of course of course are possible instead of the above highlighting.

The date of the current month when the user's scheduled recording command is input is displayed on the scheduled recording display calendar 401 or the date of the current month is displayed on the reserved recording display calendar 401 for a few days after the day when the user's scheduled recording command is input Respectively. That is, the microcomputer controls the OSD controller such that the reserved recording display calendar is displayed in the form of a calendar with respect to the dates after the present.

On the day when the reserved recording is set by the user among the plurality of dates included in the reserved recording display calendar 401, a predetermined display (e.g., a highlight) is displayed.

A plurality of dates are displayed in the reserved recording setting calendar 402. Like the case of the reserved recording displaying calendar 401, the days of the day when the user's command for the reserved recording is input Is displayed.

If the user selects a specific date from the date displayed on the reserved recording setting calendar 402, the user can select a repetition option for recording a series of broadcast programs.

This will be described with reference to FIGS. 5 to 8. FIG.

That is, when a user operates the remote control to select a highlight or a cursor displayed on the reserved recording setting calendar 402 The date is displayed as a highlight or a separate indication.

When the user inputs a reserved recording command, the microcomputer 60 may output only the reserved recording setting calendar to the OSD, as shown in FIGS. That is, the microcomputer 60 distinguishes between the reserved recording command and the reserved recording list command input by the user, and when the reserved recording command is input, the microcomputer 60 sets the reserved recording setting calendar as shown in FIGS. 5 and 6, It is possible to control so that only the output is outputted.

Information on the series, in which the reserved recording is set by the user, such as the broadcasting time and the broadcasting date, is stored in the storage means, and the microcomputer uses the information on the series stored in the storage means, Is performed.

Meanwhile, the microcomputer 60 may display a separate recording setting calendar 403 together with the display of the reserved recording setting calendar 402 in the process of setting the reserved recording by the user.

That is, when the user sets the schedule recording of a plurality of programs or a plurality of series to be broadcasted on other days of the week using the scheduled recording setting calendar 402, A separate recording setting calendar 403, which is highlighted, is further displayed.

The recording setup calendar 403 may be identical to the previous scheduled recording display calendar 401 and it may be understood that the scheduled recording display calendar 401 is also displayed during the scheduled recording setup process by the user.

On the other hand, when the user selects a specific date using the reserved recording setting calendar 402, the microcomputer 60 may list the programs to be broadcasted on the corresponding date or show the repetition option 402b You can select it first.

That is, the microcomputer 60 allows the user to set whether to repeat the recording of the series in advance, and then automatically repeats recording if the program selected by the user is a series.

FIG. 9 is an example of an OSD in which a list with scheduled recording is displayed to a user according to the embodiment of the present invention, and FIGS. 10 and 11 illustrate a process of confirming information of a program scheduled and recorded using the OSD according to the present embodiment FIG.

FIG. 9 shows the reservation recording display calendar 401 as described above, and specific dates are highlighted 401a in the reservation recording display calendar 401. FIG. That is, the microcomputer 60 controls the user interface as shown in FIG. 9 to be displayed on the screen when a command for confirming the reserved recording list is inputted by the user.

According to the foregoing description, the highlighted dates 401a may be interpreted as indicating that the reserved recording is set for the series to be broadcasted on that day.

In addition, the microcomputer 60 may control the program recording unit 401 to output a program list 401b in which information of programs for which reservation recording is currently set is displayed together with the reservation recording display calendar 401. [

For example, in the program list 401b, a program name in which scheduled recording is set by the user, a broadcast channel of the program, a broadcast time, and a broadcast date can be displayed. In a case where only the series is displayed .

10 and 11 show a case where the focused program of the program list 401b is moved. In the case where the movable focus is moved as in the case of FIG. 11 by the operation of the remote controller, Each date of the scheduled recording display calendar 401 is highlighted with respect to the scheduled recording dates.

Accordingly, the user can easily check the highlighted date on the reserved recording display calendar 401 while checking the reserved recording list by operating the program list 401b. Accordingly, it is possible to more easily perform the reservation recording and check by using the reserved recording display provided by the present embodiment and the reserved recording setting calendar.

12 is a user interface for changing a reservation recording setting of a series according to another embodiment of the present invention.

12 shows a schedule recording display calendar 401 for showing the setting state of the schedule recording and a program list 402c in which the information of the program is listed together with the schedule recording display calendar 401, do.

In the program list 402c, program information of a scheduled recording target preset by the user is listed, and whether the program is repeatedly recorded or not is also displayed.

That is, if the series reservation recording is set by the user, the series is displayed as 'Series'. In the case of a series, if only one reservation recording is set for the day / time, 'Once' is displayed.

The schedule recording display calendar 401 is highlighted with respect to the dates on which the scheduled recording program is broadcast.

On the other hand, the user can reset whether or not scheduled recording is repeated for the series using the program information output to the program list 402c. That is, if only one reservation recording is set for the program name 'Friends' and then the series is changed to the series recording, the changed contents are displayed on the reserved recording display calendar 401 as well.

In detail, if the 'Friends' program is a program broadcast on Mondays and Tuesdays, and the user has set the reserved recording only for the programs broadcasted on Monday, May 2, The microcomputer displays the schedule recording display calendar 401 on May 2, May 3, May 9, May 10, May 16, May 17, May 23 , May 24, May 30, and May 31 are all highlighted.

The microcomputer controls the program to be recorded on the date and time when the 'Friends' program is broadcasted from the program information acquired from the PSIP, by reflecting the changed scheduled recording setting.

FIG. 13 is a flowchart illustrating a process of automatically updating a scheduled recording display calendar when a broadcast date of a program in which scheduled recording is set according to the present embodiment is changed, FIG. 14 is a flowchart illustrating a schedule recording display A user interface that displays the calendar.

First, the program information is confirmed from data demultiplexed from the PSIP table received through the tuner (S201).

Then, the microcomputer confirms the reserved recording list of the set series (S202). The program name of the series for which the reserved recording is set is used or the series for which the reserved recording is set using the PID is included in the broadcasting program information Check whether there is.

That is, the microcomputer compares the broadcasting schedule information with the broadcasting program information to determine whether the schedule of the series in which the reserved recording is set is changed (S203).

As a result of the determination, if the schedule of the series to which the scheduled recording is set is different from the information of the received broadcast program, the microcomputer stores the schedule of the series to be extracted from the information of the received broadcast program (S204) , And controls the corresponding series to be recorded according to the information of the newly received broadcast program.

When the user confirms the scheduled recording list, the user is informed that the schedule of the series is changed by using a message such as a predetermined pop-up window or using a sound (S205), and the scheduled recording So that the date highlighted in the display calendar is updated (S206).

For example, when the 'Friends' program, which was scheduled to air on May 17, is changed to May 20, May 20, which is the changed date, is highlighted, as shown in FIG.

The schedule recording display calendar is automatically updated so that the user can easily obtain the information on the series set by the reserved recording.
