3 is a block diagram illustrating a broadcast receiving module of the mobile terminal shown in FIG. 1. Here, a broadcast reception module based on a digital video broadcasting handheld (DVB-H) system will be described as an example.

Referring to FIG. 3, the broadcast reception module 111 may include a radio frequency (RF) receiver 310, a DVB-T (Terristrial) demodulator (demodulator) 320, and an IP (Internet Protocol) device. A decapsulator 330.

The RF receiver 310 sets a physical channel frequency at which a broadcast channel selected by a user is transmitted, and receives a broadcast signal of a broadcast channel serviced through the set physical channel. In other words, the RF receiver 310 receives broadcast data transmitted from a broadcasting center through an antenna and outputs the broadcast data to the demodulator 320.

The demodulator 320 restores an MPEG-2 Transport Stream (TS) packet from a broadcast signal received through the RF receiver 310. The demodulator 320 demodulates broadcast data according to a transmission parameter signal (TPS) according to transmission modes 8K, 4K, and 2K provided together with broadcast data by a broadcast center. The TPS includes information on time slicing, multi-protocol encapsulated-forward error correction (MPE-FEC), availability of 4K mode, and the like.

In addition, the demodulator 320 outputs the received broadcast data to the MPE-FEC module 332 if the received broadcast data is data on which the MPE-FEC is performed, and controls the control unit if the received broadcast data is the data on which the MPE-FEC has not been performed. Output as (180). In addition, the demodulator 320 provides the time slicing module 331 with information about time slicing included in the TPS.

The IP decapsulator 330 is a time slicing module 331 that performs time slicing according to the TPS and an MPE-FEC module that performs MPE-FEC decoding when the received broadcast data is MPE-FEC encoded. 332).

The time slicing module 331 is based on the start time information of the next burst period included in the header of each MPE section and MPE-FEC section to receive the TS packet through the RF receiver 310 RF receiver 310 ) And the power of the demodulator 320. In other words, the time slicing module 331 receives the broadcast data by operating the RF receiver 310 and the demodulator 320 only in the burst duration for activating time, and in the off-time. The RF receiver 310 and the demodulator 320 are not operated. As described above, the time slicing technique reduces the power consumption of the broadcast receiving module 111 by receiving broadcast data only in the burst period, thereby minimizing battery consumption. That is, the broadcast reception module 111 reduces power consumption of the broadcast reception module 111 by selecting one of time division multiplexing (TDM) broadcast services and receiving only a burst corresponding to the selected broadcast service.

The MPE-FEC module 332 performs MPE-FEC decoding when received broadcast data is MPE-FEC encoded. In other words, the MPE-FEC module 332 confirms header information of the TS packet by performing PID (Packet Identification) filtering on the TS packet. As a result of checking the header information, if the packet identifier indicates that the packet transmits the MPE section or the MPE-FEC section, the MPE section or the MPE-FEC section is regarded as received. On the other hand, if the packet identifier does not indicate that the packet transmits an MPE section or an MPE-FEC section, program-specific information and service information are received from a TS packet to provide service information related to broadcast reception such as time slicing and whether MPE-FEC is applied. Receive. Here, MPE-FEC is a technique used to improve the performance of signal-to-noise (C / N), frequency shift (Doppler), and durability against impulse interference.

After performing the MPE-FEC decoding process, the MPE-FEC module 332 outputs the IP datagram to the controller 180. The controller 180 transmits the broadcast data decoded by the demodulator 320 and the DVB-H IP decapsulator 330 to the multimedia module 181. The multimedia module 181 outputs the decoded broadcast data to the display unit 151 by performing A / V (audio / video) decoding. That is, the multimedia module 181 reproduces the broadcast data received through the broadcast receiving module 111 and displays it on the display screen.

In this embodiment, the above-described DVB-T demodulator 320 and DVB-H IP decapsulator 330 are collectively referred to as a DVB-H demodulator.

When the broadcast menu is selected by the user, the controller 180 of the mobile terminal 100 enters the broadcast mode (S101). Here, the controller 180 enters the broadcast mode and drives the broadcast receiving module 111. The controller 180 may directly enter a broadcast mode when a shortcut key to which a broadcast function is assigned is input.

The controller 180 checks whether the broadcast service guide information (for example, EPG) for the real-time broadcast service in the current terminal is the latest version (S102). The controller 180 enters a broadcast mode and checks whether there is broadcast service guide information in the memory 160. If the broadcast service guide information is in the memory 160, the controller 180 checks a version of the broadcast service guide information. For example, the controller 180 checks whether the expiration date of the broadcast service guide information has expired. If the broadcast service guide information is not in the memory 160, the controller 180 receives the broadcast service guide information provided from the broadcast center through the broadcast receiving module 111 and stores the broadcast service guide information in the memory 160. That is, the controller 180 searches for available channels when entering the broadcast mode.

Here, the broadcast service guide information is information related to the use of the broadcast service, and includes a service identifier (ID), a service name, a service number, a service description, a service type, channel information, a keyword, a topic, a genre, a plot, and a content (program). Broadcast event information including an ID, content start time, and end time (Schedule event fragment), and the like. In addition, the broadcast service guide information includes information for connecting the terminal to the IP stream associated with the broadcast transport stream. The broadcast service guide information is EPG data and is an XML (eXtensible Markup Language) file. Referring to FIG. 5, EPG data of a service identifier, a schedule table, and a content identifier are examples of XML codes. Here, the mobile terminal 100 generates a channel list shown in FIG. 6 (a) using the service identifier, and generates a program list shown in FIG. 6 (b) using the content identifier. In addition, the mobile terminal 100 may generate the organization table of FIG. 6 (c) by using a service identifier, a content identifier, and a schedule table.

As a result of the check, if the broadcast service guide information is the latest version, the controller 180 sorts and displays the channel list based on the broadcast service guide information stored in the memory 160 (S103). Here, the controller 180 generates a channel list by using service identifier information included in broadcast service guide information.

On the other hand, if the broadcast service guide information is not the latest version, the controller 180 receives the latest version of the broadcast service guide information from the broadcast center through the broadcast receiving module 111 and updates the old version of the broadcast service guide information (update). (S113). When the update of the broadcast service guide information is completed, a service channel list is displayed based on the updated broadcast service guide information (S103). At this time, the controller 180 sorts the service channel list using the service ID information included in the broadcast service guide information.

If any service channel is selected from the displayed channel list, the controller 180 receives broadcast data of the selected service channel through the broadcast receiving module 111 (S104 and S105). The controller 180 reproduces the received broadcast data and displays the received broadcast data on the display screen (S106, S107).

In the present exemplary embodiment, the broadcast service guide information is updated by checking the version of the broadcast service guide information when entering the broadcast mode. However, the broadcast service guide information may be updated when the user requests it.

7 is a flowchart illustrating a broadcast data storage method of a mobile terminal according to an embodiment of the present invention.

Referring to FIG. 7, the controller 180 receives specific broadcast data through the broadcast receiving module 111 according to a user input, reproduces the received broadcast data, and displays the received broadcast data on the display screen (S201).

When a recording command or a capture command is input through the user input unit 130 while displaying broadcast data on the display screen, the controller 180 temporarily stores the broadcast data currently displayed on the display screen in a buffer (S202). In other words, when a user inputs a control command for recording or capturing the digital broadcast, the controller 180 records or captures the digital broadcast currently being viewed according to the control command. For example, when a recording command is input, the controller 180 starts to store broadcast data received through the broadcast receiving module 111 in a buffer from the time when the recording command is input. Meanwhile, when the capture command is input, the controller 180 stores the broadcast data displayed on the display screen in the buffer at the time when the capture command is input.

The controller 180 extracts broadcast service guide information on broadcast data currently displayed on the display screen (S203). That is, when a recording or capturing command is received from the user input unit 130, the controller 180 starts storing the broadcast data and at the same time, the service identifier (ServiceID), content identifier (ContentID) and schedule information ( Broadcast service guide information such as ScheduleEventTable) is extracted. Here, the service identifier indicates a service channel, the content identifier indicates a broadcast program, and the schedule information indicates a start / end time of the broadcast program.

When the broadcast service guide information is extracted, the controller 180 stores the captured or recorded broadcast data and the extracted broadcast service guide information together in the memory 160 (S204). Here, the controller 180 may generate and store one content as the captured or recorded broadcast data and the extracted broadcast service guide information, or may store the captured or recorded broadcast data and the extracted broadcast service guide information, respectively. For example, when receiving a recording command while watching a specific broadcast program, the controller 180 extracts broadcast service guide information such as service identifier, schedule information, and content identifier related to the specific broadcast program being viewed. The controller 180 constructs a database DB including the extracted broadcast service guide information in the recorded broadcast program. The controller 10 constructs and stores a DB list for captured or recorded broadcast data stored in the memory 160.

When constructing the DB list, the controller 180 may add flag information including whether the stored broadcast content is capture or recording. In addition, when recording a one-hour broadcast program, the sequence information may be added when divided into 20 minutes and stored.

In addition, when a search for recording and capturing content related to a recording and capturing broadcast is requested during broadcast recording or capturing, the controller 180 records and records related to the recording or capturing of the recording and capturing contents previously stored in the terminal. The captured content may be searched and linked to the recorded and captured broadcast file and stored. That is, the controller 180 stores memory address information in which the found broadcast file is stored.

In the present invention, the content generated by recording or capturing at least a portion of the broadcast being watched is stored in the memory 160, and the content stored in the memory 160 is referred to as stored content. Here, the stored content may include broadcast service guide information on recorded or captured broadcast data.

Capture and recording broadcasts stored in the memory 160 may be viewed by selecting a desired capture or recording broadcast during or after watching a broadcast.

For example, the controller 180 executes a broadcast file storage function according to a user input during or after broadcasting. The controller 180 displays a list of archive contents stored in the broadcast file archive. At this time, the controller 180 sorts and displays the storage contents according to the creation date, playback status, playback frequency, playback date, etc. of the storage contents stored in the broadcast file storage box.

When any broadcast content is selected from the displayed stored content list, the controller 180 reads the broadcast data from the memory 160 and plays the broadcast data. Subsequently, the controller 180 displays the reproduced broadcast data on a display screen.

8 is a diagram illustrating a broadcast data storing process of a mobile terminal according to one embodiment of the present invention.

First, the mobile terminal 100 receives broadcast data through the broadcast receiving module 111 according to a user's command, and reproduces the received broadcast data on the display screen.

When the recording icon 351 is input while watching the broadcast displayed on the display screen, the controller 180 of the mobile terminal 100 starts recording the broadcast being viewed. That is, the controller 180 stores the broadcast data received through the broadcast receiving module 111 in the memory 160 until the recording end command is received.

In addition, the controller 180 extracts broadcast service guide information of broadcast data being recorded.

When the recording is finished, the controller 180 stores the broadcast content 352 generated through the recording and the extracted broadcast service guide information 353 together in the broadcast content storage box. In order to check the stored broadcast content, when the desired broadcast content is selected from the broadcast content storage box, the controller 180 displays a detailed view 354 of the selected broadcast content. In the detailed view, the broadcast service guide information on the broadcast content may be edited or the broadcast content may be included in a message and transmitted.

9 is a flowchart illustrating a related content providing method of a mobile terminal according to a first embodiment of the present invention.

Referring to FIG. 9, when the 'content library' function is selected according to a user's menu operation, the controller 180 executes a content library function (S301). The controller 180 displays a list of stored contents stored in the memory 160 on the display screen. Here, the stored content may be broadcast data recorded or captured according to the above-described broadcast data storage method or content downloaded from a content providing server through the wireless communication unit 110.

If any one of the stored contents stored in the content library is selected and a play command is input, the controller 180 starts playing the selected stored content according to the play command (S302 and S303).

The controller 180 starts playback of the selected archived content and searches for the content associated with the reproduced archived content among the archived contents stored in the memory 160 (S304). Herein, the controller 180 searches for the contents including the broadcast service guide information mapped to the broadcast service guide information of the stored content being reproduced among the stored contents stored in the memory 160. For example, the controller 180 searches for content including content ID information corresponding to the content ID '1010001' of the broadcast content being played among the broadcast contents stored in the terminal.

As a result of the search, when the archive content associated with the content being played is retrieved from the contents library, the controller 180 outputs a notification signal informing of this and processes the retrieved archive contents (S305 and S306). The notification signal includes a notification message, a notification voice message, a notification sound, and the like.

If there is no result found in step S305, the controller 180 searches for real-time broadcast content mapped to broadcast service guide information of the content being played in the broadcast service guide information for the real-time broadcast content (S315).

When the real-time broadcast content is found, the controller 180 processes the searched real-time broadcast content (S316, S306).

In the above-described embodiment, the related content search is performed as an example when the playback of the selected archived content is started. However, the related content search may be performed after the playback of the selected archived content is completed or before a predetermined time for the completion of playback of the archived content. Can be.

10 is a flowchart illustrating a method of processing retrieved content stored in a mobile terminal according to the present invention.

Referring to FIG. 10, the controller 180 of the mobile terminal 100 determines the processing of the searched content according to a control signal input from the user input unit 130 after displaying the search result of the related content.

When receiving the control signal transmitted from the user input unit 130, the controller 180 checks whether the control signal is a selection command of the 'ear' function (S321). That is, the controller 180 checks whether the control signal is a command for instructing playback of the searched content following the currently playing broadcast content.

As a result of the check, if the control signal is the following command, the controller 180 checks whether the reproduction of the broadcast content currently being played is completed (S322).

When the reproduction of the broadcast content is completed, the controller 180 reads out and retrieves the retrieved content from the memory 160 (S323).

If the control signal input through the user input unit 130 in the step (S321) is a selection command of the 'view immediately' function, the controller 180 stops the playback of the currently playing broadcast content, and plays the searched content by (S324, S325). When the playback of the retrieved content is completed, playback of the interrupted content is resumed.

On the other hand, if the control signal input through the user input unit 130 in the step (S321) is a cancel or end command, the controller 180 disappears the screen displaying the search results, and continues to play the broadcast content being played back. .

11 is a flowchart illustrating a searched real-time broadcast content processing method of a mobile terminal according to the present invention.

When the real time broadcast content associated with the currently playing broadcast content is found, the controller 180 compares the current time with schedule information included in the broadcast service guide information of the found real time broadcast content.

For example, the controller 180 checks whether the current time is before the broadcast start time of the searched real-time broadcast content (S331).

As a result of the check, if the current time is before the broadcast start time, the controller 180 checks whether there is a viewing or recording reservation setting (S332). In other words, the controller 180 checks whether there is a viewing or recording reservation setting request for the found real-time broadcasting content. Here, if there is a reservation setting request, the controller 180 sets a broadcast start time as a reservation time.

After the reservation setting, the controller 180 checks whether the current time matches the reservation time (S333).

If the current time coincides with the reservation time, the controller 180 receives the found broadcast content through the broadcast receiving module 111, reproduces and displays the received broadcast content, or records the received broadcast content ( S334). Here, the controller 180 can output a notification signal when watching a broadcast or recording starts.

If the current time is not before the start time of the broadcast content in step S331, the controller 180 checks whether the current time is before the end time of the broadcast content (S335). If the current time is before the end time, the controller 180 receives the found real-time broadcast content through the broadcast receiving module 111. The controller 180 reproduces and displays the received broadcast content or records the received broadcast content (S336).

In step S335, if the current time is after the broadcast end time, the controller 180 determines that the related content search has failed. At this time, the controller 180 notifies that the broadcast of the searched real-time broadcast content has ended and displays broadcast schedule information of the corresponding broadcast content. The user may set a viewing reservation and a recording reservation using the broadcast schedule information.

12 is a flowchart illustrating a method for providing associated storage content of a mobile terminal according to a second embodiment of the present invention.

When the broadcast menu is selected by the user, the controller 180 enters the broadcast mode according to the user's selection (S401).

When entering the broadcast mode, the controller 180 displays a channel list by using service identifier information of broadcast service guide information (S402). In this case, the controller 180 may read the broadcast service guide information from the memory 160 or receive the broadcast service guide information through the broadcast receiving module 111.

If the related storage content is requested while displaying the channel list, the controller 180 searches for the associated storage content for each channel displayed on the display screen (S403 and S404). That is, when the user searches for the related archived content by the user, the controller 180 searches for the related contents among the recorded and captured contents stored in the broadcast file storage box by using the broadcast service guide information. At this time, the controller 180 checks the similarity between the service identifier information of each channel in the channel list and the service identifier information of the stored content stored in the broadcast file storage box. The controller 180 determines the corresponding storage content as the association data when the identified similarity is greater than or equal to the threshold value.

When the associated search is completed, the controller 180 displays the searched result for each item of the channel list (S405). The controller 180 may display the number of relevant search results for each channel or display the presence or absence of the related search results.

When any one of the displayed related search results is selected, the controller 180 displays a list of searched results in a popup form (S406 and S407). For example, when an icon representing a result of a related search result is selected by a user, the controller 180 displays a related search result corresponding to the selected icon on a display screen. At this time, the controller 180 assigns a priority to the related search result based on the stored time, similarity, and the like, and displays the sorted results according to the assigned priority.

In the present embodiment, the recording / capture contents stored in the terminal are described as an example. However, the present invention is not limited thereto, and the recording / capture contents stored in the other terminal may be searched through short-range wireless communication or wireless communication.

When the content stored in the other terminal is selected, the mobile terminal requests the provision of the corresponding content to the other terminal. The other terminal transmits the corresponding content to the mobile terminal requesting the provision of the content through wireless communication.

13A to 13D illustrate an example in which a mobile terminal according to a second embodiment of the present invention provides storage contents associated with entering a broadcast mode.

According to FIG. 13A, when a broadcast menu is selected by a user, the controller 180 enters a broadcast mode and drives the broadcast receiving module 111. The controller 180 displays a channel list based on the broadcast service guide information. In this case, the broadcast service guide information is provided from the broadcast center through the broadcast receiving module 111 or read from the memory 160.

In addition, when any one channel of the channel list displayed on the display screen is selected, the controller 180 displays a preview screen 361 of the selected channel. The channel list display screen includes a favorite channel registration / cancellation icon 362 for registering / cancelling a favorite channel of a channel which is being previewed and a channel search icon 363 which is used when a search for a channel viewable in the current region is required. Include. When using the broadcasting function for the first time, the user can search for a viewable channel by using the channel search icon 363.

When the associated search icon 364 located in each channel item of the channel list is selected by the user, the controller 180 recognizes that the request for providing the storage content associated with the channel item is requested. The controller 180 searches for the archive content associated with the corresponding channel item in the broadcast file archive. For example, when a touch is detected on the related search icon located in the “BBC News 24” item in the channel list, the controller 180 searches for the archive content associated with the broadcast service guide information for the BBC News 24 in the broadcast file box.

As a result of the search, when the archive content associated with the channel item for which the related search is requested is found, the controller 180 displays an indicator 365 indicating that the archive content has been searched on the display screen (FIG. 13B). For example, if three archive contents that match the service identifier of BBC News 24 are found, the controller 180 displays an icon indicating the number of search results.

When the displayed indicator 365 is selected, the controller 180 displays a list of searched results in a popup window (FIG. 13C). The playback icon 366 is positioned for each search result item displayed in the popup window. When the list of search results is displayed, the controller 180 sorts and displays the searched stored contents according to the creation date, the degree of association, the playback status, the number of playbacks, and the like.

When any one item of the searched result list is selected, the controller 180 reads out and reproduces the stored content of the corresponding item from the broadcast file storage box and displays the reproduced storage content on the display screen (FIG. 13D).

In the present embodiment, the user performs a related search for a specific channel selected as an example. However, when the user enters a broadcasting mode, all the channels in the channel list are searched for the stored contents associated with each channel to search the stored contents for each channel. It can also be implemented to indicate the presence of.

14 is a flowchart illustrating a method for providing associated storage content of a mobile terminal according to a third embodiment of the present invention.

When the user selects a specific broadcast channel, the controller 180 receives broadcast data provided through the corresponding broadcast channel through the broadcast receiving module 111, reproduces the received broadcast data, and outputs the received broadcast data to the display unit 150. (S501).

The controller 180 receives an associated search command from the user input unit 130 while playing and displaying broadcast data received through the broadcast receiving module 111 (S502).

When the input of the associated search command is detected, the controller 180 extracts broadcast service guide information on broadcast data currently displayed on the display screen (S503). That is, the controller 180 extracts a service identifier, a content identifier, and schedule information for the broadcast program currently being viewed.

When the broadcast service guide information is extracted, the controller 180 searches for the archive content associated with the displayed broadcast data in the broadcast file box using the extracted broadcast service guide information (S504). In other words, the related broadcast contents are searched by mapping the extracted broadcast service guide information and broadcast service guide information of the stored contents stored in the broadcast file storage box.

When the search is completed, the controller 180 displays a list of the searched storage contents on the display screen (S505).

When any one item of the displayed list is selected, the controller 180 reads the storage content corresponding to the selected item from the broadcast file storage box and transmits it to the multimedia module 181 (S506).

The multimedia module 181 reproduces the received storage content under the control of the controller 180 and transmits the received storage content to the display unit 151 (S507). The display unit 151 displays the reproduced storage content provided from the multimedia module 181 on the display screen (S508).

At this time, the controller 180 reproduces the broadcast data received through the broadcast receiving module 111 and displays it on the display screen, and displays the reproduced storage content on a portion of the display screen. For example, the controller 180 may display broadcast data that is currently broadcast on the main screen of the display unit 151 using picture in picture (PIP) technology, and display reproduced content on the sub-screen.

Alternatively, the controller 180 may stop receiving broadcast data received through the broadcast receiving module 111 and display the reproduced stored content on a display screen. At this time, the controller 180 stores the broadcast data received through the broadcast receiving module 111 in the memory 160 while the storage content is reproduced and displayed on a display screen. The broadcast data stored in the memory 160 may be reproduced and displayed.

15A to 15F illustrate an example of providing storage content associated with a broadcast being watched by a mobile terminal according to a third embodiment of the present invention.

According to a control command input by the user, the controller 180 A / V decodes the broadcast data received through the broadcast receiving module 111 and displays the same on the display screen (FIG. 15A). If a touch is detected on the display screen on which the broadcast data is displayed, the controller 180 displays control icons (FIG. 15B).

If the associated search icon 371 is selected from the control icons, the controller 180 extracts broadcast service guide information on the broadcast program being viewed. The controller 180 searches for the archive content associated with the broadcast program being viewed using the extracted broadcast service guide information. In this case, the controller 180 may display an indicator or a message indicating that the associated search is in progress on the display screen (FIG. 15C).

When the associated search is completed, the controller 180 displays the searched result in the popup window 372 (FIG. 15D). If any one of the displayed search result lists is selected, the controller 180 reads the stored content corresponding to the selected result from the memory 160 and displays a preview screen (FIG. 15E). If a touch is detected on the play icon 373 on the preview screen, the controller 180 plays the corresponding content. At this time, the controller 180 displays the broadcast service guide information stored with the corresponding content on the display screen (FIG. 15F). In the present embodiment, the broadcast service guide information is superimposed and displayed on the storage content playback screen as an example. However, by dividing the display screen, the content playback screen is displayed in one of the divided areas, and the broadcast service guide is displayed in another area. Information can be displayed.

16 is a flowchart illustrating a method for providing associated storage content of a mobile terminal according to a fourth embodiment of the present invention.

The controller 180 of the mobile terminal 100 receives and reproduces broadcast data provided through a specific broadcast channel (S601). The controller 180 displays the reproduced broadcast data on a display screen.

While the broadcast data is being reproduced, the mobile terminal 100 detects an entry into a broadcast non-receiving area such as an out of coverage (OOC) or a broadcast reception restriction area in which the mobile terminal 100 cannot receive the broadcast data being viewed (S602). ).

When the mobile terminal 100 detects an entry into a broadcast unreceivable area, the controller 180 extracts broadcast service guide information on broadcast data currently being viewed (S603).

When the broadcast service guide information is extracted, the controller 180 searches for the stored content associated with the broadcast data being viewed (S604).

If the stored content associated with the broadcast data is found, the controller 180 reproduces the found stored content (S605). Here, if there is only one searched stored content, the controller 180 immediately reproduces the stored content and displays it on the display screen. On the other hand, if there is more than one searched archived content, the controller 180 displays the searched archived content list, and if any one of the displayed stored content lists is selected, the selected content is played back and displayed.

On the other hand, if the stored content associated with the broadcast data is not retrieved, the controller 180 outputs a notification signal indicating that there is no retrieved stored content. In this case, the controller 180 may display channel information that can be received at the current location or execute a broadcast file storage.

17A to 17F illustrate an example of providing storage content associated with interrupted broadcast data when the mobile terminal according to the third embodiment of the present invention enters a broadcast unreceivable region.

If the mobile terminal 100 enters the OOC area while watching a broadcast, the controller 180 detects this. The controller 180 detecting the entry of the OOC region stops the reception of the broadcast signal and changes the indicator 381 indicating the reception strength of the broadcast signal to the indicator 382 indicating that the broadcast signal cannot be received (FIG. 17A-17B). In addition, the controller 180 displays a notification message 383 informing the user that broadcast viewing is impossible.

Subsequently, the controller 180 searches for archive content associated with broadcast data that has been stopped. For example, when watching the Ch 003 and entering the OOC area and receiving a broadcast signal is impossible, the controller 180 checks whether there is content generated from broadcast data provided by Ch 003 among the stored contents stored in the broadcast file storage box. .

When the search is completed, the controller 180 displays a list of search results in a popup window 384 (FIG. 17C). When any one of the search result lists is selected, the controller 180 displays a detail view window 385 of the stored content corresponding to the selected result on the display screen (FIG. 17D).

When a touch is detected on the play icon 386 of the detail view window 385, the controller 180 plays the corresponding content and displays the content on the display screen (FIG. 17E). If the mobile terminal 100 leaves the OOC area while watching the reproduced content, the controller 180 outputs a pop-up window 387 to the display unit 151 indicating that the broadcast can be viewed (FIG. 17F). When a response to the query displayed in the popup window 387 is input, the controller 180 performs the following operation according to the response. That is, the controller 180 receives and displays broadcast data that has been interrupted through the broadcast receiving module 111 when an affirmative response is received, and continues to play the content when a negative response is received.

18 is a flowchart illustrating a method of providing associated storage contents of a mobile terminal according to a fifth embodiment of the present invention.

Referring to FIG. 18, the controller 180 enters a viewing reservation setting mode according to a user input in operation S701. The controller 180 displays a viewing reservation setting screen on a display screen.

After entering the viewing reservation setting mode, the controller 180 sets a viewing reservation according to data input through the user input unit 130 (S702). In other words, the controller 180 inserts data input by the user into each field displayed on the viewing reservation setting screen. The viewing reservation setting screen includes fields such as a reservation date, a viewing time, a broadcast channel or a broadcast program, and associated storage content search activation / deactivation. When data input is completed in each field of the viewing reservation setting screen, the controller 180 stores viewing reservation information in the memory 160 according to a user command.

When the viewing reservation setting is completed, the controller 180 checks whether the associated storage content search function is activated through the set viewing reservation information (S703).

As a result of the check, if the associated archived content search function is active, the controller 180 searches for the archived content related to the broadcast data reserved for viewing in the broadcast file box (S704). That is, the controller 180 searches for the recorded or captured content associated with the reserved broadcast channel or broadcast program in the broadcast file library.

On the other hand, if the check result, if the associated archive content search function is inactive state, the controller 180 enters step S611.

When the search for the related archived content is completed, the controller 180 checks whether there is a searched related archived content (S705).

If there is the searched related storage content, the controller 180 further sets a viewing reservation time in consideration of the playing time of the searched storage content (S706). Here, when there are two or more searched stored contents, the controller 180 additionally sets a viewing reservation time in consideration of the total playing time of the searched stored contents. For example, if the search time of the two stored contents is 45 minutes and 1 hour, respectively, and the viewing reservation time is 20 o'clock, the controller 180 sets the viewing reservation time to be 18 to play and view the searched storage contents before the viewing reservation time. Set additional time to 15 minutes. That is, 18:15 is additionally set as the viewing reservation time in addition to 20:00.

In step S705, if there is no searched related storage content, the controller 180 enters step S711.

After additionally setting the viewing reservation time in consideration of the playback time of the retrieved stored content, the controller 180 checks whether the current time coincides with the set additional viewing reservation time (S707).

If the current time coincides with the set additional viewing reservation time, the controller 180 outputs a notification signal indicating that the archive content associated with the viewing-reserved broadcast has been searched (S608). That is, the controller 180 notifies the user that there are archive contents associated with the broadcast program reserved for viewing.

When a viewing approval response is input from the user input unit 130 with respect to the notification signal, the controller 180 reproduces the corresponding storage content and displays it on the display screen (S709 and S710).

If the search rejection response of the searched stored content is input, the controller 180 performs step S711.

If the current time does not coincide with the additionally set viewing reservation time in step S707, the controller 180 checks whether the current viewing time and the set viewing reservation time coincide with each other (S711). That is, the controller 180 checks whether the viewing reservation time is reached.

If the current time coincides with the set viewing reservation time, the controller 180 drives the broadcast receiving module 111 to receive broadcast data received through a viewing reserved broadcast channel, and reproduces and displays the received broadcast data. (S712).
