The present invention relates to a digital broadcasting receiver and a method for reproducing data broadcasting thereof, and more particularly, to a digital broadcasting receiver for storing contents of a broadcasting web site (BWS) during data broadcasting, and replaying the stored contents later. And a content processing method for data broadcasting.

The digital broadcast receiver receives and displays various digital broadcast signals. Digital broadcasting digitally modulates various multimedia signals such as audio, video, and text and provides them to the digital broadcasting receiver. Currently, the digital broadcasting method that can be serviced can be largely divided into DMB (Digital Multimedia Broadcasting) and DVB (Digital Video Broadcasting). DMB can be further divided into terrestrial DMB (also called T-DMB) and satellite DMB.

On the other hand, portable terminals are increasingly equipped with a multimedia processor or multimedia functions, and digital broadcasting receivers are among the multimedia functions. The portable terminal may be a wireless terminal, a notebook computer, a PDA, or the like.

Data services provided by digital broadcasting include BWS, MOT slide show, XML-based Electrical Program Guide (EPG), Voice EPG (voice voice board), real-time travel information and transportation Includes a Transport Protocol Expert Group (TPEG) and an interactive service for providing information.

In particular, the content provided by the BWS service transmits data related to a web site to a digital broadcast receiver using a multimedia object transfer (MOT) protocol. The digital broadcast receiver temporarily stores the content of the received BWS to provide the user with the web service in a form similar to the Internet web service even if there is no reverse channel.

However, the BWS service periodically transmits fixed data using the MOT protocol. Such data may be changed and transmitted according to the circumstances of the broadcasting station. Therefore, it is not easy for the user to save the content of the desired BWS. In particular, because the content of BWS includes linked pages that can be accessed through various paths, it is not easy to find such data and store it manually.

The BWS service is content that broadcasts various data at once. However, since a large amount of data is transmitted through the BWS service, it is difficult to search all the contents at once. Due to the broadcasting characteristics, the user cannot maintain all the contents while watching.

And since the user needs a broadcast connection every time in order to use the contents of the desired BWS, it is cumbersome. In addition, when the data of the content of the connected BWS is changed, there is also a problem that can not be used as information.

Accordingly, a first object of the present invention is to enable a user to store desired content while viewing BWS.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. At this time, it should be noted that the same components in the accompanying drawings are represented by the same reference numerals as possible. In addition, detailed descriptions of well-known functions and configurations that may blur the gist of the present invention will be omitted.

1 is a block diagram showing a digital broadcast receiver 10 according to an embodiment of the present invention. 2 is a block diagram illustrating in detail the control unit 24 of FIG. 1.

1 and 2, the digital broadcast receiver 10 includes a key input unit 12, a digital broadcast receiving unit 16, a data processing unit 18, a display unit 20, a speaker 22, a controller 24, and the like. And a memory 34.

The key input unit 12 provides a plurality of keys for the operation of the digital broadcast receiver 10, and generates and transmits key data according to a user's key selection to the control unit 24. At this time, the user's command generated through the key input unit 12 may be storage, playback and management of the content of the BWS.

The digital broadcast receiver 16 receives the digital broadcast signal through the antenna 14, demodulates the received digital broadcast signal, and outputs digital broadcast data. In particular, the digital broadcast receiver 16 receives and demodulates the content signal of the BWS and outputs the content data of the BWS.

The data processor 18 decodes and outputs the content data output from the digital broadcast receiver 16. That is, the data processor 18 decodes the content data using the MOT protocol and outputs the web-based content and directory. The data processor 18 determines whether the content data is compressed and decompresses the compressed content data.

The display unit 20 and the speaker 22 reproduce and display the content data decoded by the data processing unit 18. In this case, the content is displayed in the form of a web page on the display unit 20 as described above.

The controller 24 controls the overall operation of each part of the digital broadcast receiver 10. In particular, the control unit 24 performs a function of storing, playing and managing content.

The memory includes a read only memory (ROM), a random access memory (RAM), and a flash memory. The ROM stores a program and various reference data necessary for controlling the operation of the digital broadcast receiver 10, and an Erasable Programmable ROM (EPROM) may be used. The RAM provides a working memory of the controller 24, and an SRAM (Static RAM) may be used. The flash memory provides an area for storing various updatable storage data, and stores data generated during control by the controller 24 or during use by the user. As the flash memory, a NAND type flash memory such as NAND or OneNAND may be used. In particular, the ROM stores programs for storing, playing and managing contents. RAM or flash memory temporarily stores the content data received periodically. The user-selected content is stored in flash memory.

In particular, the controller 24 temporarily stores the content data received from the broadcasting station in real time in the memory 34. When the viewing of the content ends, the temporarily stored content data is deleted from the memory 34. Since the same data is repeatedly received in real time from the broadcasting station, the control unit 24 manages not to overwrite the content data received with the same ID during temporary storage. Of course, when the content data is updated and received, the control unit 24 checks this to update the content data and temporarily stores the content data in the memory 34.

The control unit 24 includes a storage selector 26, a reproduction selector 28, a playback unit 30, and a management unit 32 for performing functions related to the processing of the content being viewed. The storage selector 26 selects content to be stored from among the received and displayed contents and stores the selected content in the memory 34. The playback selector 28 selects content to be played back from contents stored in the memory 34. The playback unit 30 plays the selected content on the screen of the display unit 20. The manager 32 performs a management function such as deleting the stored content from the memory 34 or changing the name of the stored content.

At this time, the storage selector 26 selects content to be stored and then blocks reception of data related to the content to be stored. The storage selector 26 stores the selected content received in the digital broadcast receiver 10 in the memory 34 until the time point of selecting the content to be stored.

In addition, the storage selector 26 generates a group label and a mapping table in order to effectively store the selected content in the memory 34. That is, since the content data has a plurality of folder / file structures, the storage selector 26 generates a group label for managing them. The storage selector 26 generates a mapping table for storing the selected content based on the directory information of the selected content. The storage selector 26 stores the selected content in the memory 34 according to the generated mapping table. The storage selection unit 26 displays the state in which the storage of the selected content is completed on the display unit 20 so that the user can confirm it.

The reproduction unit 30 generates directory information and a mapping table in order to effectively reproduce the content selected by the reproduction selection unit 28. That is, the playback unit 30 generates directory information of the selected content. The playback unit 30 generates a mapping table for displaying the selected content based on the generated directory information. The playback unit 30 displays the initial page of the selected content according to the mapping table on the screen of the display unit 20. The initial page may be changed according to the mapping table, but one of the pages included in the selected content may be selected. For example, a page displayed on a screen or a home page of the selected content may be used as the initial page when storing the selected content.

The memory 34 stores content selected by the user. Stored content is temporary stored content at the time of selecting content to store. The stored content includes a page linked to the selected content. Meanwhile, as described above, the temporarily stored content is deleted regardless of the user's command through the key input unit 12, but the content stored by the user's selection is deleted only by the user's command through the key input unit 12.

Content processing method of data broadcasting

3 is a flowchart illustrating a content processing method of data broadcasting according to an embodiment of the present invention. 1 and 3, a content processing method according to an embodiment of the present invention includes a content storing process (S41), a content selecting process (S43), a selected content playing process (S45), and a stored content managing process (S47). It is configured to include.

The content storage process S41 is a process of storing, in the memory 34, the content selected by the user's key input unit 12 among the contents of the BWS being viewed through the digital broadcast receiver 10. The content selection process to be played back (S43) is a process of selecting content to be played back from contents stored in the memory 34. The selected content reproduction process S45 is a process of reproducing the selected content through the display unit 20 and the speaker 22. The stored content management process (S47) is a process of performing a management function such as deleting the stored content from the memory 34 or changing the name of the stored content. The stored content management process S47 is performed after the content storage process S41.

First, the content storage process S41 will be described in detail with reference to FIGS. 1 and 4. 4 is a flowchart illustrating a content storage process S41 during data broadcasting of FIG. 3.

When the user selects the BWS channel during data broadcasting through the key input unit 12 (S411), the content of the BWS received by the digital broadcasting receiver 10 is displayed on the screen of the display unit 20 (S413). The user watches the content displayed on the screen of the display unit 20. At this time, the memory 34 temporarily stores the content data received periodically.

Next, a process of selecting content to be stored from among contents displayed on the screen is performed (S415). When the user finds content to be stored while viewing the content, when the user selects the content to be stored through the key input unit 12, the storage selection unit 26 performs a process for storing the selected content. The storage selector 26 stores the content data temporarily stored in the memory 34. Meanwhile, when key data for performing another function is input through the key input unit 12, the controller 24 performs the corresponding function (S417).

When the content to be stored is selected, the storage selection unit 26 blocks reception of data related to the content to be stored (S419). The reason for blocking the reception of content data is to limit the range of content to be stored. That is, the BWS periodically transmits content data, and thus the received content data is temporarily stored in the memory 34 while being updated. Therefore, if the reception of data related to the content to be stored is not blocked, a problem arises that the range of the content data to be stored is not limited.

In addition, before the reception of the data is interrupted, the content signal or the content data that has already been received through the antenna 14 but not temporarily stored in the memory 34 is ignored or passed through the digital broadcast receiver 16 and the data processor 18 to the memory. May be temporarily stored at 34.

The storage selector 26 generates a group label for managing the selected content (S421). The storage selector 26 generates a mapping table for storing the selected content based on the directory information of the selected content (S423). The storage selector 26 stores the selected content in the memory 34 according to the generated mapping table (S425). The storage selection unit 26 displays the state in which the storage of the selected content is completed on the screen of the display unit 20 so that the user can confirm it (S427).

In this case, the content stored in the memory 34 by the user's selection may include a page displayed on the screen of the display unit 20 at the time of selection, and may include a home page and a linked page of the selected content.

The content selection process S43 and the content reproduction process S45 to be reproduced will be described in detail with reference to FIGS. 1 and 5 as follows. 5 is a flowchart illustrating a content selection process S43 and a selected content reproduction process S45 of FIG. 3.

The content selection process (S43) to be played back begins with a process of selecting a stored content menu (S431). That is, when the user selects the stored content menu through the key input unit 12, the display unit 20 displays menu items under the control of the control unit 24 (S433). At this time, the menu item includes a playback menu and a management menu.

When the user selects a playback menu from the menu items displayed through the key input unit 12 (S435), the playback selecting unit 28 displays the content item stored in the memory 34 on the screen of the display unit 20 (S437). .

In operation S439, a process of selecting content to play is performed. That is, when the user selects the content to be played back from the content item displayed through the key input unit 12, the play selector 28 selects the selected content as the content to be played back.

If content to be played next is selected, the selected content playback process (S45) is performed. First, the playback unit 30 generates directory information of the selected content (S451). The playback unit 30 generates a mapping table for displaying the selected content based on the generated directory information (S453). The playback unit 30 reproduces the initial page of the selected content according to the mapping table on the screen of the display unit 20 (S455).

In this case, the user may watch the selected content through the screen of the display unit 20.

Next, a process of determining whether the user selects a page linked through the key input unit 12 is performed by the controller 24 (S457).

When the user selects the linked page through the key input unit 12, the controller 24 determines whether the linked page is stored in the memory 34 again. If there is a linked page, the controller 24 displays the linked page on the screen (S461). If there is no linked page, the controller 24 displays on the screen that there is no linked page (S463).

Meanwhile, when key data for performing another function is input through the key input unit 12, the controller 24 performs the corresponding function (S465).

A process of managing the stored content (S47) will be described in detail with reference to FIGS. 1 and 6 as follows. 6 is a flowchart illustrating a management process S47 of stored content of FIG. 3.

When the user selects the management menu from the menu items displayed through the key input unit 12 (S471), the controller 24 displays the management menu on the screen (S473). At this time, the management menu includes a delete menu and a rename menu. When the other menu item is selected, the controller 24 performs a corresponding function (S475).

If the delete menu is selected in the management menu (S477), the management unit 32 displays the stored content item (S479). When the user selects the content to delete through the key input unit 12 (S481), the management unit 32 deletes the selected content from the memory 34 (S483).

If a name change menu is selected in the management menu (S485), the management unit 32 displays the stored content item (S487). When the user selects content to be renamed through the key input unit 12 (S489), a name input window for inputting a name is displayed on the screen. In this case, an existing name of the selected content may be displayed in the name input window. The user inputs a name into the name input window through the key input unit 12 and stores the name (S491 and S493), so that the management unit 32 changes the name of the previously stored content to the newly input name.

 If a menu other than the above-described management menu is selected, the management unit 32 performs a corresponding function (S495).
