Recently, an IP set-top box that can use an IP broadcasting service such as a video on demand (VOD) service that provides various contents programs through the Internet has been commercialized.

As various types of digital broadcasting and IP broadcasting services are implemented, more channels and contents can be viewed, and broadcasting channels and VOD services are more flexibly operated. In order to allow viewers to select a broadcast program according to the increase in the number of channels or the change in channel allocation, an electronic program guide (EPG) corresponding to the program schedule is transmitted through an empty frequency band or a spare channel, Displayed on the viewer, the viewer can grasp the program for about a week using the EPG.

In addition, recent set-top boxes and televisions have a large storage capacity such as a large hard disk, and provide a personal video recording (PVR) function for recording various contents received through a digital broadcast or VOD service. have. Accordingly, the user can pre-record desired content on the hard disk using the EPG and play the content at a desired time.

Although users have recorded a lot of content on the hard disk through scheduled recording, they are often unable to play it because of busy daily life. In addition, although the number of broadcast channels has increased, the reality is that there is a lot of re-broadcasting programs for re-broadcasting programs or content previously broadcasted due to content poverty. Accordingly, in some cases, content stored on the hard disk but not played back is transmitted to the re-broadcast through the broadcast channel at the present or near time.

In this case, the user may prefer to watch the high quality re-broadcast without having to play the content stored on the hard disk, but to check whether the content is re-broadcast or whether the program being re-broadcast is already stored on the hard disk. This can be cumbersome because you have to check the list of recorded content and EPG separately.

Therefore, the present invention was created to solve the above problems, and an object of the present invention is to provide a method for displaying recorded content stored in a storage medium in association with program organization information or preferred channel information.

DETAILED DESCRIPTION Hereinafter, an embodiment of a method of displaying recorded content according to the present invention will be described in detail with reference to the accompanying drawings.

The present invention can be applied to a broadcast receiver such as a set-top box or a television or an IP set-top box that receives digital broadcast such as terrestrial broadcast, satellite broadcast, and cable broadcast.

As shown in FIG. 1, the broadcast receiver 100 to which the present invention is applied includes a tuner 10, a demux 20, a storage 30, an MPEG decoder 40, an A / V processor 50, On Screen Display (OSD) generator 60, memory 70, the control unit 80, etc. may be configured, the tuner 10 and the demux 20 is a broadcast receiver, MPEG decoder 40 and A The / V processor 50 may be bundled into a broadcast reproducing unit.

The tuner 10 tunes a broadcast channel requested by a user and receives a broadcast signal provided through the broadcast channel. The demux 20 receives program data and system information of an MPEG-2 transport stream from the received broadcast signal. The system information is classified and output, and broadcast information such as a corresponding broadcast channel number and a broadcast channel name may be included in the system information and transmitted to the controller 80.

The program data separated from the demux 20 is recorded in storage 30 such as a hard disk, an optical disk, a flash memory, or restored to video and audio data by the MPEG decoder 40, and the A / V processor 50 The converted video and audio data is converted into a format that can be output from an external device such as a TV or a speaker and output.

The OSD generator 60 generates a menu screen of the broadcast receiver 100 or generates and generates an EPG screen by using the EPG data that the tuner 10 receives on a separate channel or separates from the demux 20. One screen is output to the A / V processor 50.

The memory 70 may store user information such as data related to a menu screen of the broadcast receiver 100 or a user preferred channel, or temporarily store EPG data or data related to the operation of the broadcast receiver 100. The volatile memory and the volatile memory may be combined.

The controller 80 receives a user's request input through a remote controller, a button, or a touch screen and controls each element of the broadcast receiver 100 to perform an operation according to the user's request.

The controller 80 controls the tuner 10 and the demux 20 to record the broadcast program selected by the user in the storage 30, and generates information about the broadcast program recorded in the storage 30. The storage 30 may be managed as a separate file or may be managed as recording channel information in the memory 70.

The recording channel information includes the number of programs or contents stored in the storage 30 and information about each recording program (or recording content). The information about each recording program includes a program identifier (or program name) and metadata. , All or at least part of the broadcast date, broadcast time, playback time (duration), channel (channel number, channel name), recording resolution (recording mode), recording position, and the like.

In addition, when the user selects a broadcast channel as a preferred channel through an input device such as a remote controller, an operation button, or a touch screen, the controller 80 prefers information (channel number and channel name) about the preferred channel selected by the user. It generates one item of channel information and stores it non-volatile in the memory 70, and controls the OSD generator 60 in response to a user's request for displaying a favorite channel based on the preferred channel information managed in the memory 70. You can create and display a list screen.

In addition, when the user requests an EPG through an EPG button provided on the remote controller, for example, the controller 80 selects a channel providing the EPG through the tuner 10 and separates the EPG data through the demux 20. In addition, the EPG screen may be generated and output to the TV through the OSD generator 60 based on the separated EPG data.

Generates information (channel number and channel name) about a favorite channel selected by the user as one item of the favorite channel information and stores the information nonvolatilely in the memory 70, and the OSD generator 60 for the user's preferred channel display request. The controller may generate and output a preferred channel list screen based on the preferred channel information managed in the memory 70.

In the present invention, the recording channel information and the preferred channel information or the recording channel information and the EPG data are linked to be displayed on the same screen or directly connected to each other with a minimum of operation to improve the user's convenience.

2A and 2B illustrate an embodiment of the present invention in which a recording channel item is included in a preferred channel list.

In the embodiment of Figure 2, the preferred channel list screen 'SBS', KBS2 ',' KBS1 ',' EBS ',' MBC ',' National Geographic 'channel is displayed, the recording channel' 1 night 2 days' , 'Champions final' and 'I'm a singer' are marked as a recording program, and 'EPG' is displayed as an icon in '1 Night 2 Days' section of the recording channel, and 4 directions for moving to each item Button is displayed.

In an embodiment of the present disclosure, the controller 80 searches for the preferred channel information and the recording channel information managed in the memory 70 according to the user's request for displaying the preferred channel list, and based on the OSD generator 60, the controller 80 searches for the preferred channel information. By controlling, a favorite channel list screen is generated. In this case, an item called 'recording channel' may be added to the favorite channel list by managing broadcast program recordings (contents) as one virtual channel that the user prefers.

In the preferred channel list screen of FIG. 2A, a user selects each channel item and a recording channel item specified by the user by operating the up and down arrow buttons of the remote control, for example, and the selected channel is operated when the OK button is operated while one channel item is selected. Can be selected, and when the recording channel item is selected, the left and right arrow buttons are operated, the up and down arrow buttons are used to select one of the recorded programs stored in the storage 30, and the selected recording program is played through the OK button. Can be.

In the recording channel item, all of the recorded programs stored in the storage 30 may be displayed, or only the recorded programs related to the preferred channel among the recorded programs stored in the storage 30, that is, the preferred channels included in the preferred channel list. Only programs that have been tuned through and recorded through may be displayed.

In the latter case, the controller 80 may search for a recorded program recorded through a channel included in the preferred channel information among the recorded programs included in the recording channel information, and list only the found recorded programs in the 'recording channel'. .

FIG. 2B illustrates another embodiment in which only a recording program related to a favorite channel is displayed on a 'recording channel' when the recording channel item is included and displayed on the favorite channel list screen. If there is a recorded program, the corresponding recorded program may be displayed side by side on the right side of the corresponding item.

Meanwhile, a predetermined icon ('EPG' mark in FIG. 2) may be displayed for a program to be broadcast within a predetermined time among the recorded program items displayed in the 'recording channel' to indicate that the corresponding recorded program may be broadcast again soon. have.

To this end, the controller 80 compares the program identifiers and / or meta data of the recorded programs displayed on the favorite channel list screen with the EPG data, and within a predetermined time, for example, within 1 hour, based on the current time in the EPG data. Among the programs to be broadcasted, find a program that matches the identifier of the recorded program or the meta data or similar program that is displayed on the favorite channel list screen. Can be displayed.

In addition, the controller 80 may operate the OSD generator 60 when the user operates the 'EPG' button of the remote controller while the recording program item in which the 'EPG' mark is displayed on the 'recording channel' of the favorite channel list screen is selected. The control may generate an EPG screen including a program corresponding to the selected recorded program item (the channel and time at which the program is to be broadcast).

Therefore, the user can not only remember which program is stored on the hard disk through the frequently used favorite channel list screen, but also display EPG information such as channel and broadcast time for the re-broadcast program related to the recorded program to be displayed. By checking, you can choose to watch the recorded program or the rebroadcast program.

That is, the user may play back a part of the recorded program stored in the storage because there is currently a short time, and then re-broadcast the corresponding recorded program again at a time checked through the EPG information, thereby providing convenience.

3 illustrates an embodiment of the present invention in which recording channel information is displayed together on an EPG screen.

In general, since the EPG screen has a space limitation, information of a predetermined time, for example, three hours, is displayed in one direction (the time axis in the horizontal direction in FIG. 3), and the channel axis in the vertical direction in the other direction (FIG. 3). Information on a predetermined number of channels is displayed. To view EPG information of another channel or another time zone, the user may move using up, down, left, and right buttons.

According to an embodiment of the present invention, a separate 'recording channel' (a kind of virtual channel) is provided on the upper part of the EPG screen, that is, the upper part of the time axis displaying the time, so that the recording programs stored in the storage 30 can be listed. You can list the recorded programs in the order in which they were recorded or vice versa, and make the cell size (length in the direction of the time on the EPG screen) of each displayed program proportional to the duration of the recorded program. Can be.

In the recording channel, all of the recording programs stored in the storage 30 may be displayed, or only the recording programs related to the channel displayed on the current EPG screen among the recording programs stored in the storage 30 or the current EPG screen. Only recorded programs related to the displayed program, i.e., only recorded programs that match the identifier of the program currently displayed on the EPG screen or whose meta data matches or are very similar may be displayed.

In the latter case, the controller 80 searches for among the recorded programs included in the recording channel information, the recorded program matching the identifier of the recorded program recorded through the channel displayed on the current EPG screen or the program displayed on the current EPG screen. Only the recorded program can be listed in the recording channel.

In addition, when a recording channel has a recording program that matches the program currently displayed on the EPG screen, the program cell of the EPG screen ('1 night and 2 days' in FIG. 3) and the recording program cell of the preferred channel (Fig. 3 shows the same symbol, symbol, or icon ('** 1' in FIG. 3), respectively, on '1 night and 2 days (2011-05-29)', allowing the user to make the same program as the cell's program hard. By knowing that the disc has already been recorded, you can choose whether to watch the recorded program recorded on the hard disk or the program rebroadcast at that time.

Alternatively, if the recording channel is not displayed separately when displaying the EPG screen, and instead, a recording program identical or similar to the program included in the current EPG screen is stored in the storage 30, a symbol or a symbol in the corresponding program cell. In addition, the user may be informed that a recording program identical or similar to a program of a corresponding cell is stored in the storage 30.

FIG. 4A illustrates an embodiment of the present invention displaying EPG information related to content included in a recording channel list together, and FIG. 4B illustrates a comparison of content included in the recording channel list and EPG information related thereto. Another embodiment of the invention is shown.

When a user requests a list of recorded programs stored in the storage 30 through a menu screen of the broadcast receiver 100 or through an operation of a remote controller, the controller 80 controls the OSD generator 60 to control the memory 70. Based on the recording channel information managed in the system, a recording list screen including information of a recording program name, duration, recording resolution, etc. is generated and output to the screen, and the user operates the recording list by operating a direction button or a number button. By selecting the recorded program item included in the screen and operating the confirm button, the recorded program of the selected item can be viewed.

If a recorded program item is selected on the recording list screen, the controller 80 may provide all or part of information on the selected recorded program item, that is, program identifier (or program name), metadata, channel (channel number, channel name), and the like. In the EPG data, find a program that matches or similar to the metadata or a program that matches the identifier of the recorded program that is identified among programs to be broadcast within a predetermined time, for example, within 1 hour, based on the current time, as shown in FIG. 4A. In addition, information about the found program, for example, broadcast date, broadcast time, channel, program name, broadcast resolution, etc. may be generated in a separate window and displayed next to the selected recorded program item.

Accordingly, the user can select which program to play or watch by comparing the recorded program with a program that will be broadcast again soon. The recording program selected in FIG. 4A, '1 night and 2 days' has a recording resolution of 'SD'. The broadcast resolution of '1 Night 2 Days (Re)' which will be re-broadcasted soon will be 'HD', so if you want to watch the program with high quality, you can watch '1 Day 2 Days (Re)' of 'HD' during the broadcast time. Or, if there is a different schedule in the corresponding broadcast time can be played by watching the '1 night 2 days' of the recording program 'SD' stored in the storage 30.

On the other hand, in the embodiment of FIG. 4B in which the recording list and the EPG data are displayed in association, when there is EPG data related to the recording program item included in the recording list screen, a predetermined icon or an 'EPG' mark is displayed on the corresponding item. When the EPG button is operated while the corresponding item is selected, each element of the corresponding recorded program item and corresponding program item included in the EPG data, that is, date (recording date and broadcast date), time, channel, program name, and resolution (recording) The screen comparing the resolution and the broadcast resolution) may be displayed as a new window.

To this end, the controller 80 compares program identifiers and / or meta data of the recorded program items included in the recording list screen with EPG data within a predetermined time based on the current time, based on the current time in the EPG data. For example, a program to be broadcasted within one hour is searched for a program that matches or similar to metadata or a program that matches the identifier of the recorded program displayed in the recording list, and when a program is found, the OSD generator 60 is controlled to 'EPG'. A predetermined icon such as a mark can be generated and displayed on the recorded program item displayed in the recording list.

Thereafter, when the user operates the EPG button of the remote controller while the user selects the recorded program item displaying the 'EPG' mark, the controller 80 searches for the program corresponding to the selected recorded program item from the EPG data to display information about the corresponding program. The control unit may control the OSD generator 60 to generate a screen for comparing the information of the recorded program and the corresponding program for each element and output the screen in a new window.

When the items of the recorded program are selected on the screen comparing each element, for example, the corresponding recorded program can be played through the OK button. When the EPG item is selected, the scheduled viewing of the corresponding program is set by the OK button. May be

Therefore, the user can not only check recorded programs through the recording list screen, but also easily check whether related programs are to be broadcasted soon, and compare recorded programs with programs to be re-broadcasted. The convenience of being able to choose whether to watch a rebroadcasted program is gained.
