BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable communication device capable of receiving and reproducing IPTV broadcast content, and more particularly, to a technique of providing related keywords for playing IPTV broadcast content and displaying search result contents according to a selected associated keyword on a screen.

Existing news services were divided into news contents for news programs of the press and news contents for news programs of the broadcasters, and were provided through different service platforms (newspaper / web, TV). However, according to the recent N-Screen service flow and the selection of media companies for comprehensive programming channels, newsML metadata technology for TV services and TV news and Web news in an IPTV environment are produced when producing IPTV news programs. There is a need for a TV + web-linked newsML metadata technology related to the production of various TV + web-linked news services, but the existing technology does not support it. While there is a great demand for the use of IPTV services in web media and social network platforms, the Open API provided by current web portals and social network services platforms has many limitations in the use of IPTV services in web media. In order to produce IPTV service based on the existing web media contents, the individual services must be produced based on web technology (TV newspaper, YouTube TV, etc.) for each service, which requires a lot of cost and time. Therefore, there are bound to be a lot of restrictions on the IPTV service utilization of web media contents.

It provides a variety of additional information, such as to be able to use the advertising or promotion.

However, from the standpoint of a portable communication device that can receive such IPTV service and additional information, it is difficult to display a myriad of additional information on the screen. In general, a portable communication device displays associated keywords extracted from content metadata on a screen while playing IPTV broadcast content, searches for contents that are additional information corresponding to the associated keyword selected by the user among the displayed associated keywords, and retrieves the searched contents. Lists can be displayed on the screen. However, when the number of related keywords or the search content is numerous, it is difficult to display all of them on a small screen.

According to the present invention, if the portable communication device is to provide additional information related to the broadcast content while playing the IPTV broadcast content, the technical solution may be provided to provide additional information on a limited basis while satisfying the user's requirements, rather than providing all the additional information found. For the purpose of providing it.

According to an aspect of the present invention, there is provided a portable communication device capable of providing limited additional information in consideration of a screen size, a touch screen for user input and screen output, a broadcast receiving unit for receiving IPTV broadcast content, and the reception. Display the associated IPTV broadcast content on the touch screen, display the associated keyword for the played IPTV broadcast content on the touch screen, and display a search result for the selected related keyword among the displayed related keywords on the touch screen. And a controller configured to vary the number of search results displayed on the touch screen according to at least one of a range, intensity, and time of a touch input made by the user on the touch screen.

Further, the portable communication device further includes an input unit for activating the associated keyword search of the user, wherein the controller is an area for a touch input for performing a partial region of the touch screen on the touch screen according to an input through the input unit. Set it.

According to the present invention, since the user can limit or expand the number of contents search, it is very easy when searching contents using a communication device such as a smartphone having a small display screen. In addition, the communication apparatus according to the present invention stores the search history information and reuses it in the future, thereby creating an effect of reducing the search time and reducing the network load.

1 is a configuration diagram of a dynamic combined authoring system for IPTV utilization of web media contents.

The system includes web portal server 110, DCC server 120, meta database schema 130, and keyword dictionary module 140 configurations. Dynamically coupled authoring systems that include these configurations have the following characteristics.

First, the system includes a technology for defining converged content metadata for adaptive service utilization of comprehensive media contents (news and magazines) in an IPTV environment. This technology has the definition of metadata for IPTV news / magazine production and metadata matching for broadcasting, and defines convergent metadata for the interworking of news / magazine programs for IPTV and web news / magazine programs.

Second, the system includes the Import API technology for adaptive use of web media (web portal / social network) in IPTV environment. This technology defines the Open API-based standard service Import API to utilize IPTV service of web portal contents. Import API definition includes XML based Title, image, text matching support Import API definition, Web resource (resolution, codec, bitrate, etc.) analysis and service metadata interworking technology. The system also defines an Open API-based standard service Import API for the use of IPTV services in social network service platforms. This definition includes content access control and collection function based on user's online social relationship, import API definition based on user profile (name, address, interest), and import API definition based on social network relationship information.

Third, this system includes the structure of dynamic combined service platform and the creation / management technology for adaptive service of multimedia contents in multi-screen environment. This technology defines dynamic coupling metadata (service metadata), meta schema and DB structured technology based on service meta, dynamic binding service creation and management technology, and template server technology based on dynamic binding metadata (service metadata). It includes.

This is because it provides TV + web linked service model related to production of various TV TV + web linked news service such as NewsML metadata for TV service and comprehensive news program linking TV news and web news in IPTV environment. Have a difference. Also, it is different from the existing in that it defines standard Import API optimized for creation of IPTV service and creates related S / W module based on Open API provided by web media platform provider. In addition, the dynamic combined service platform structure (service metadata definition, service meta based meta schema and DB structure, dynamic combination required for the production of various IPTV services based on web media (general media company content, web portal media, social content)) It is different from the existing one in defining service creation module).

In addition, it is possible to generate and provide services for IPTV based on web contents of comprehensive media, web portal contents and social network media contents. In addition, since each creation time for each existing web domain was too much use time and cost, there were many limitations in service activation.However, utilizing the service platform as described above greatly improves time and cost, thereby creating many advantages in service activation. do.

As shown, the portable communication device includes a touch screen 210, a broadcast receiver 220, and a controller 230. The touch screen 210 is a user interface for a user's touch input and screen output. The broadcast receiver 220 is a receiver for receiving IPTV broadcast content. The controller 230 includes a playback module for playing back IPTV broadcast content received through the broadcast receiver 220 and a control module for controlling the overall portable communication device. The controller 230 reproduces the IPTV broadcast content received through the broadcast receiver 220 on the touch screen 210. In addition, the controller 230 extracts the associated keyword from the metadata for the IPTV broadcast content and displays it on the touch screen 210. The list is displayed on the touch screen 210. Herein, the additional information may be content in which content having different formats, such as text and image, is dynamically combined.

According to an aspect of the present invention, the control unit 230 touches by varying the number of search list of additional information in consideration of at least one of the intensity, range, and time when the user touches the touch screen 210 to select the associated keyword. Display on screen 210. For example, the controller 230 reduces the number of search lists displayed on the touch screen 210 when the touch intensity is low, and increases the number of search lists displayed on the touch screen 210 when the touch intensity is high. In addition, the controller 230 may reduce the number of search lists displayed on the touch screen 210 as the touch range is narrower, and the number of search lists displayed on the touch screen 210 may be increased as the touch range is wider.
For example, when the left and right lengths of the touch screen 210 are 5 cm, the controller 230 may set the number of search lists to three when the touch range is 1 cm, and the controller 230 may search when the touch range is 3 cm. You can adjust the number of lists to nine.
In addition, the controller 230 may reduce the number of search lists displayed on the touch screen 210 as the touch time is short, and the number of search lists displayed on the touch screen 210 as the touch time is longer. When the number of search lists is limited and displayed on the touch screen 210, the controller 230 may display the search lists on the touch screen 210 in order of high priority according to a condition such as a search recommendation order. . Furthermore, the controller 230 may store the search history information and reuse it in the future, thereby reducing the search time and reducing the network load.
