The control unit 170 of the image display apparatus 100 drives a web browser (S910). As described with reference to FIG. 4 or 5, the web browser may be driven through the web browser application in the application layer 455 or the application layer 550.
For example, a web browser may be driven through a smart system platform mounted on the processor 330.
Web browser driving may be performed by user input. For example, as shown in FIG. 10, when a web browser item in the home screen is selected, the web browser may be driven.
Meanwhile, the home screen of FIG. 10 will be described below.
The home screen 1000 of FIG. 10 is an initial screen when the power is on or in the standby mode, or is provided in the local key (not shown) or the remote controller 200. The home screen may be set as a default screen by an operation of a home key (for example, a 'menu' button).
In order to implement such a home screen, the smart system platform may be mounted on the processor 330 or a separate processor in the controller 170.
The home screen 1000 of FIG. 10 broadly displays, from a broadcast video area 1010 displaying a broadcast video 1001, items from various sources (for example, content providers or applications such as CPs) by list. A card object area 1020 having card objects 1021 and 1022, and an application menu area 1030 including a shortcut menu of application items. The home screen may further include a login item and an exit item.
Meanwhile, the broadcast image area 1010 and the application menu area 1030 may be fixedly displayed with items or objects therein.
The card object area 1020 may be displayed by moving or replacing the card objects 1021 and 1022 therein. Alternatively, each item in the card objects 1021 and 1022 (eg, an item “yakoo”) may be displayed by being moved or replaced.
For example, by using a pointer displayed in response to the movement of the remote control apparatus 200, each item in the card object 1021 or 1022 or the card objects 1021 and 1022 may be selected, and moved left or right. In this case, the selected card object or the selected item may be displayed to be moved left / right or replaced and replaced with another card object or another item.
Meanwhile, as shown in FIG. 10, when the home screen is displayed on the display 180, when the location of the pointer 1005 is in the broadcast image 1001, an arrow-shaped pointer 1005 may be displayed.
In the drawing, the application menu area 1030 is displayed at the bottom of the screen. The application menu area 1030 may include a search item, an app store item, a web browser item 1035, a media link item 1038, a social network service item, an additional application view item, and the like.
When the web browser item 1035 in the application menu area 1030 is selected using the remote controller 200, the controller 170 of the image display apparatus 100 may drive a web browser. Alternatively, when the web key is provided in the remote control apparatus 200, the web browser may be driven by the operation of the web key.
Next, a predetermined web page is accessed using a web browser (S915). The connected web page is displayed on the display (S920).
The controller 170 of the image display apparatus 100 may drive a web browser and control the user to access a predetermined web page through the web browser.
For example, when a specific web address is input by a user input or when there is a web address set as a default, the control unit 170 of the image display apparatus 100 may correspond to the network interface unit 130. The web server 510a may be controlled to transmit an access request, and the source data of the web page may be received from the web server 510a.
The controller 170 configures a web page screen by using source data of the received web page, and controls to display the configured screen on the display 180.
FIG. 11A illustrates an example of a web page screen 1110 displayed on the display 180 of the image display apparatus 100. Meanwhile, a menu 1100 related to a web browser may be displayed at the bottom of the web page screen 1110.
The web page screen 1110 of FIG. 11A is media data in a web page, and includes mp3 based audio data 1115, mp4 based first video data 1120, and flash based second video data 1125. To illustrate. In addition, the web page screen 1110 further includes text data.
Meanwhile, the menu 1100 related to the web browser includes a previous screen item, a home screen item, a zoom item, a thumbnail item, a favorite item, a search item, a media list view item 1105, an exit item, and the like. can do.
Next, it is determined whether a media data item exists in the connected web page (S925), and, if applicable, a media list in the web page (S930). When there is a media list display input in the connected web page (S935), the generated media list is displayed (S940).
The controller 170 determines whether a media data item exists in the connected web page by using source data of the received web page. In this case, the media data item may be any one of video data, image data, and music data.
The controller 170 may extract the media tag in the source data of the received web page, and determine whether the media data item exists by using the media tag.
For example, in the case of video data, the media tag may be a 'Video' tag, an 'Object' tag, an 'Embed' tag, or the like.
The controller 170 determines whether there is a 'Video' tag, an 'Object' tag, an 'Embed' tag, or the like, among the source data of the received web page, and if so, determines that there is video data.
Meanwhile, the controller 170 obtains the URL address of each video data by using the 'src' attribute in the 'Video' tag, the 'data' attribute in the 'Object' tag, and the 'src' attribute in the 'Embed' tag. can do.
Meanwhile, the controller 170 may check the file format of each video data using the 'y' ype 'attributes in the' Video 'tag, the' Object 'tag, and the' Embed 'tag.
As another example, in the case of image data, the media tag may be an 'img' tag or the like.
The controller 170 determines whether there is an 'img' tag among the source data of the received web page, and if so, determines that there is image data.
Meanwhile, the controller 170 obtains the URL address of each image data by using the 'src' attribute in the 'img' tag, the 'data' attribute in the 'Object' tag, and the 'src' attribute in the 'Embed' tag. can do.
As another example, in the case of music data, the media tag may be an 'Audio' tag, an 'Embed' tag, a 'bgsound' tag, or the like.
The controller 170 determines whether there is an 'Audio' tag, an 'Embed' tag, a 'bgsound' tag, and the like among the source data of the received web page, and if so, determines that there is music data.
Meanwhile, the controller 170 may obtain the URL address of each music data by using the 'src' attribute and the like in the 'Audio' tag, the 'Embed' tag, and the 'bgsound' tag.
Meanwhile, the controller 170 may check the file format of each music data using the 'type' attribute in the 'Audio' tag, the 'Embed' tag, and the 'bgsound' tag.
On the other hand, the control unit 170 generates a media list including the media data by using the above-described media tag. In this case, the media list may include at least one of a media name, a media type, and a preview image.
Meanwhile, in order to generate the preview image, the controller 170 may control to download the media data in the connected web page.
As described above, since the URL address in which the media data is stored appears in the 'src' attribute and the 'data' attribute in the media tag, the control unit 170 uses the corresponding URL address to control the network interface unit 130. Through the control, the corresponding media data is downloaded.
In this case, each media data may be stored in a web server, or alternatively, may be stored in another content server. Accordingly, the video display device 100 requests each server to transmit the media data, and receives the media data from each server. In this case, when authentication is required for the server, the controller 170 of the image display apparatus 100 may control to transmit authentication information to the server.
Meanwhile, some of the media data included in the web page to which the image display apparatus 100 is connected may be downloaded, but others may not be downloaded.
To this end, the controller 170 of the image display apparatus 100 may generate a media list without excluding downloadable media data.
The controller 170 may generate a preview image by using the downloaded media data or the media data related information. The preview image at this time may be generated based on the image extracted from the media data.
Meanwhile, the downloaded media data may be stored in the storage 140.
Meanwhile, the media list may include at least one of a media name or a media type without the above-described preview image.
Accordingly, when generating the media list, the controller 170 may generate the media list immediately by using the media tag in the source data.
For example, the media name can be generated by using the URL address and file name where each media data is stored in the 'src' and 'data' attributes in each media tag. Can be created using the 'type' attribute in the tag.
In this case, the URL address where each media data is stored may be stored in the storage 140.
The controller 170 may control to automatically display the generated image list within a predetermined time after displaying the connected web page.
Alternatively, if there is a media list display input by the user input, the controller 180 may control to display the generated image list.
For example, as illustrated in FIG. 11A, when the media list item 1105 is selected from the menu 1100 related to the web browser displayed on the display 180, the controller 180 displays the generated media list. You can control the display.
FIG. 11B illustrates that the media list 1130 is displayed in overlap with the connected web page screen 1110.
Since the displayed web page screen 1110 of FIG. 11A includes mp3 based audio data 1115, mp4 based first video data 1120, and flash based second video data 1125, FIG. The media list 1130 may include an audio data item 1150, a first video data item 1155, and a second video data item 1160. In the figure, each media data item includes a media name, a media type, and a preview image.
Meanwhile, the media list 1130 may include a media list view object 1135 in a currently accessed web page, and a recently played media list view object 1140 including recently played media data. When the object 1140 is selected, the recently played media list 1530 as shown in FIG. 15B may be displayed.
Meanwhile, the media list view object 1135 in the currently accessed web page in the media list 1130 of FIG. 11B may be focused and displayed.
Next, it is determined whether a predetermined media data item in the media list is selected (S945). If applicable, the selected media data is played (S950). The media data related screen to be played back is displayed (S955). The media data to be played back or the address information of the media data to be played back is stored (S960).
When a predetermined media data item in the displayed media list is selected, the controller 170 controls access to the corresponding server 510b using URL address information corresponding to the media data. The server 510b then requests media data transmission.
Then, the control unit 170 controls to play the downloaded media data. For example, the image processor 320 or the audio processor (not shown) in the controller 170 controls the playback of the media data. Then, the screen to be reproduced or a related screen during reproduction is controlled to be displayed on the display 180.
For example, when music data is played, image data attached to the music data may be displayed on the display 180.
As another example, when moving image data is reproduced, the reproduced moving image data may be displayed on the display 180.
Meanwhile, the media data to be played back or URL address information of the media data may be stored in the storage 140. In addition, information (DRM), authentication information, etc. required for reproduction may be further stored in the storage 140. As such, the media data stored in the storage 140 or URL address information of the media data may be utilized when displaying a recently played media list.
FIG. 11C illustrates that the first video data item 1155 of FIG. 11B is selected and the screen 1170 to be played is displayed on the display 180. In this case, a menu 1100 related to the web browser may be displayed together at the bottom of the playback screen 1170.
In this case, the playback screen 1170 may be a screen separate from the web page screen 1110. That is, the media data may not be reproduced on the web browser, but may be reproduced separately through the media play in the image display apparatus 100.
On the other hand, as described above, when the media data included in the web page is collectively displayed through the media list, and the user selects the desired media data, the media data is downloaded and played by downloading the media data. Since there is no need to play on, there is an advantage that a media player for playing media data is not installed in a web browser.
On the other hand, it is possible to use the media player installed in the video display device 100, not on the web browser, so that the media data can be stably reproduced. In addition, since the update of the media player installed in the video display device 100 is simpler, the latest media data can be reproduced through continuous updating.
