Description

System for providing optional services for IPTV broadcasting {System of providing optional services for IPTV broadcasting}

The present invention relates to IPTV broadcasting, and more particularly, to a technology for providing additional information related to broadcasting during IPTV broadcasting.

IPTV (Internet Protocol Television) refers to a service that provides information service, video content, and broadcasting to a television receiver using a high-speed Internet network. It's a type of digital convergence in terms of the convergence of the Internet and television. To use such an IPTV, only a television receiver, a set-top box, and an Internet line need to be connected. That means you can add a set-top box or dedicated modem to your television and turn it on just as you would turn on the television. Therefore, even a person who is not familiar with a computer can use the remote control to receive various contents and additional services provided by the Internet such as watching movies, home shopping, home banking, online games, and MP3s as well as searching the Internet.

In the case of an IPTV system, a broadcaster requires an IPTV headend system, which is a base system for broadcasting, and a set-top box is required for a receiving subscriber. An IPTV headend receives and processes broadcast content largely (encoding and compression multiplexing). It has the infrastructure to send out afterwards, and it also has various functions such as subscriber information, contract information, organization and receiving authority control. As described above, the set-top box is a device required to watch IPTV broadcasts and refers to a device that can directly connect with a subscriber's TV to watch broadcasts. The main functions include controlling basic functions and paying broadcasts for watching broadcasts. To give only viewing rights to authorized subscribers, and to store / execute broadcasting applications for two-way broadcasting.

On the other hand, a technique for providing additional information for IPTV broadcasting is known. This allows the user to select by presenting the associated keyword of the IPTV broadcast content being played on the user terminal, such as a public display device, on the screen. For example, if the broadcast content is a drama, the main character of the drama, the shooting background, etc. may be displayed on the screen as an associated keyword. When the user selects an association keyword, the selected association keyword information is transferred to a server providing additional information, and the server searches for and extracts the content corresponding to the association keyword and returns it to the user terminal. Accordingly, the user can obtain additional information about the broadcast.

However, the related keyword providing environment of the related art is mostly provided by web services. In addition, the technology for providing a related keyword is a method of providing a keyword that is not related to broadcast content or a related keyword through simple matching of keywords provided by a web service even if related to the broadcast content. When searching for and extracting additional information from the server and returning it to the user terminal, if the additional information is composed of different formats such as text, still image, and video, an editing process of combining them into one content using an appropriate template is performed. In addition, the production process must be performed in accordance with the IPTV broadcasting format. Therefore, considerable time delay is inevitable, which is a great obstacle in providing smooth additional information.

An object of the present invention is to provide a technical scheme that can quickly service additional information of IPTV broadcasting.

In addition, an object of the present invention is to provide a technical scheme that can provide an optimal keyword for IPTV broadcasting.

The additional service providing system for IPTV broadcasting according to an aspect of the present invention for achieving the above technical problem receives the IPTV broadcast content and the meta-information of the IPTV broadcast content, and the received IPTV broadcast content in the common channel screen area The relevant keyword for the IPTV broadcast content being played, extracted from the meta information, displayed on the screen or transmitted to the user-specific mobile device, and one or more related keywords selected from the user-specific mobile device are transmitted to the outside. A public display device for requesting additional information related to IPTV broadcasting content and reproducing broadcast type web content, which is received additional information, according to the request to a part of the screen designated by a corresponding user; Holds broadcast-type web content and the transmitted one A service for receiving an associated keyword of the mobile terminal, searching for broadcast web content corresponding to the received one or more related keywords among the plurality of broadcast web contents, and transmitting the searched broadcast web content to the public display device. It includes a provisioning server.

The service providing server may include a broadcast type web corresponding to the received one or more related keywords based on the meta information of the series-based web content for each subject generated by combining the content metadata for each category and the content metadata classified according to the recommendation of the broadcasting reporter. Search for content.

The public display apparatus plays one broadcast type web content most selected or unanimously selected from a mobile device for each user among web contents played in a user-designated area of the full screen on the public channel screen.

According to the present invention, since the content, which is additional information of the IPTV broadcast, is produced and retained in advance in accordance with the IPTV broadcast format, the additional information can be quickly provided as the content can be provided by itself without any editing or processing when the additional information is requested. The effect can be created.

As illustrated, the additional information providing system for IPTV broadcasting includes mobile devices 110, 120, and 130, a common display apparatus 200, and a service providing server 300. In the illustrated example, for convenience of explanation, it is assumed that three users are using the common display apparatus 200. The mobile devices used by each of the three users are the first mobile device 110, the second mobile device 120, and the third. Defined as a mobile device 130. The mobile device may be a smart device that can communicate with and control the common display device 200. The common display apparatus 200 is an apparatus for receiving and reproducing IPTV broadcasting. The screen of the common display apparatus 200 may be divided into a common channel playback screen and a personal channel playback screen as shown in FIG. 2. IPTV broadcast content is basically played on the common channel playback screen. The personal channel playback screens play content, which is additional information requested for each mobile device user. That is, content that is additional information requested by a first user who uses the first mobile device 110 is played on the first personal channel playback screen, and second mobile device 120 is used on the second personal channel playback screen. 2 Content, which is additional information requested by the user, is reproduced, and content, which is additional information requested by a third user, using the third mobile device 130, is reproduced on the third personal channel playback screen.

The service providing server 300 retains contents that are additional information related to IPTV broadcasting content being played on the common display apparatus 200. These additional information are made up of broadcast type web contents made for the IPTV broadcast format. That is, the service providing server 300 retains a plurality of broadcast web contents that are designed for the IPTV broadcast format. In addition, the service providing server 300 holds meta information about the series-based web content for each topic generated by combining the content metadata for each category and the content metadata classified according to the broadcast reporter's recommendation. Broadcast reporters, in particular, broadcast reporters of a comprehensive channel provider categorizes subjects according to specialized classification criteria for content, which is utilized in the present invention. Figure 3 is shown to help understand this.

As metadata databases for contents stored in the content database, there is a content metadata database by category and a content metadata database by reporter recommendation. Metadata stored in the content metadata database for each category is classified into content metadata according to general categories. The categories are divided into sports, politics, and culture as illustrated, and subcategories of sports include baseball, soccer, and figure skating. Belongs. The metadata stored in the content metadata database for each reporter recommendation is classified by the reporter. For example, as shown in the contents related to Kim Yu-na, sports Kim Yu-na, political Kim Yu-na, culture Kim Yu-na, etc. are divided into Kim Yu-na's technology, Kim Yu-na's competition, Kim Yu-na's competitors, and so on.

The series content metadata database is a database newly created from a category content metadata database and reporter recommendation content metadata database. The series content meta information database contains meta information about a series of series web contents. Here, the subject matter may be a sports field, a politics / culture field, or the like as shown. In FIG. 3, Kim Yu-na is an example, and the Kim Yu-na series contents belonging to the sports field are classified as Kim Yu-na's technology, Kim Yu-na exhibition and Kim Yu-na competitors, and the Kim Yu-na series contents belonging to the politics / culture sector are Pyeongchang Winter Olympics and Sports Korean Wave and Advertising. Are classified as Series web contents are produced based on the series content meta information database, and series web contents are produced in accordance with the IPTV broadcasting format in advance. The produced series web contents are stored in the series web contents storage unit for IPTV broadcasting.

Hereinafter, an overall operating embodiment of the system described above will be described.

First, the public display apparatus 200 receives IPTV broadcast content from the service providing server 300 and reproduces the content on the entire screen or the common channel reproduction screen region. In addition, the common display apparatus 200 receives meta information about IPTV broadcasting content, extracts an associated keyword included in the received meta information, and displays the same on the screen. For example, if a broadcast about Kim is currently being played, related keywords (sports field, politics / culture field, etc.) related to the subject areas that Kim belongs to are displayed on the screen. Users may select different related keywords by manipulating their mobile devices among the related keywords displayed on the screen. If the sports field is selected, the common display apparatus 200 displays sub-related keywords (technology, competition, competitor, etc.) belonging to the sports field on the screen. Accordingly, the user operates the mobile device again to select the desired associated keyword. For reference, when the common display apparatus 200 displays an association keyword on a screen, the association keyword may be applied by applying an association structure (tree structure, star structure, etc.) designated for each subject. When the final association keyword is selected for each user through the above procedure, the public display apparatus 200 transmits the association keyword finally selected for each user to the service providing server 300.

The service providing server 300 receives an associated keyword selected for each user from the public display apparatus 200. The service providing server 300 searches the series content meta information database with the received related keywords and checks the corresponding meta information. The service providing server 300 extracts a series web content corresponding to the checked meta information from the series web content storage unit and transmits the series web content to the public display apparatus 200. As described above, since the last selected association keyword may be different for each user, the service providing server 300 may transmit the series web content to the public display apparatus 200 by classifying the user. In this case, the service providing server 300 transmits the series web content extracted from the web content storage unit to the common display device 200 without any processing or editing. This is possible because the series web content itself is made for the IPTV broadcast format. Accordingly, the service providing server 300 does not need to perform a series of processes of dynamically combining, editing, and converting the retrieved contents to the IPTV broadcasting format.

The public display apparatus 200 receives a series web content for each user transmitted from the service providing server 300. The common display apparatus 200 plays the series web content of the first user in the first personal channel playback screen area, plays the series web content of the second user in the second personal channel playback screen area, and plays the series of third users. The web content is played in the third channel playback screen area. In addition, the common display apparatus 200 transmits the series web content of the first user to the first mobile device 110, transmits the series web content of the second user to the second mobile device 120, and transmits the third user's series web content to the first mobile device 110. The series web content may be transmitted to the third mobile device 130. Accordingly, each of the first mobile device 110, the second mobile device 120, and the third mobile device 130 may play the received series web content.

Meanwhile, a process of selecting any one of the series web content being played on each personal channel playback screen may be performed through negotiation between the common display apparatus 200 and the mobile device. This will be described in detail below. Each user may operate his or her mobile device to vote for the most favorite content among various contents being played on the personal channel playback screen of the public display apparatus 200. Referring to FIG. 4, (a) of FIG. 4, IPTV broadcasting content is playing on a common channel playing screen, and series web content, which is additional information selected by each user, is playing on each individual channel playing screen. When the user manipulates his or her mobile device to select the desired content from the contents played on the personal channel playback screens, the number of selections may be reflected by an asterisk as shown in FIG. 4 (b) shows that content being played on the first personal channel playback screen is selected from two users. The common display apparatus 200 displays the series web content that is most or unanimously selected by the users in the entire screen as shown in FIG.

So far I looked at the center of the preferred embodiment for the present invention. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. Therefore, the disclosed embodiments should be considered in an illustrative rather than a restrictive sense.
