Description

Method for providing broadcasting data and system for same

The present invention relates to an IPTV set-top box, and more particularly, after a server and a set-top box receive broadcast data from a broadcasting station, a method and system for providing broadcast data for retrieving a user expected query list from the server and transmitting the same to the set-top box. It is about.

As the IPTV market is active, the set-top box market is also growing.

The set-top box refers to a product that receives digital video and audio signals transmitted from a broadcasting station through a terrestrial wave, satellite cable, or high speed network, and displays them on a display device through a TV.

Currently broadcast worldwide, broadcast is divided into satellite, cable, and terrestrial according to the transmission method. Satellite and cable broadcasting is already being digitized, and terrestrial broadcasting is now being digitized worldwide. Since terrestrial broadcasting can basically provide broadcasting service with free viewing or low-cost viewing fees, digital terrestrial broadcasters' choice of digital broadcasting is expected to increase when terrestrial broadcasting is completed.

To watch digital broadcasts, digital receivers such as digital TVs and set-top boxes are required. Accordingly, demand for digital TVs and set-top boxes with digital tuners will continue to increase until 2015 when global analog broadcasting is scheduled to end.

At present, IPTV provides various services. For example, text message (SMS: service to send text message to mobile phone while watching TV) and home caller ID display (CID: interworking with home phone to watch TV and register on TV The number of callers is only displayed on the TV screen, and the two-way media service, such as a service that displays the caller's number on the TV screen, is closer to the real-time service of IPTV. This feature adds the 'multimedia communication service' function to the interactive services such as news, weather, TV newspaper, karaoke, shopping, and finance, which were previously provided by IPTV.

Meanwhile, a broadcasting station transmits BIFS data together with a broadcast signal. For example, if the BIFS data is broadcasted and you like the main character's clothes, you can click on the clothes and go to the home shopping to purchase clothes or download the songs if you like the songs in the drama or the drama to the VOD service. You can see it again.

Also, if you select an object because you are curious about the profile of the announcer while watching the news, the profile for that object, that is, the announcer, is displayed.

As such, when the user selects the object information that he wants to know while watching TV, the information is expressed through BIFS data. The existing DMB and ACAP (Advanced Common Application Platform), a terrestrial digital TV, transmits the data signal to the terrestrial broadcast signal. Load it together and send it.

However, even the information displayed by selecting an object for this, there is a bandwidth burden to transmit and receive the terrestrial broadcast signal, and thus cannot provide a variety of information.

At present, the method of expression is bidirectional contents, but in a true sense, it is a method of providing information based on a scenario that is not bidirectional.

In order to provide and receive interactive content, the use of data transmitted with the content must be transmitted. Current terminals (DMB, TV) are unidirectional receivers and cannot transmit.

In addition, in the current broadcasting environment, technologies such as analog broadcasting, digital broadcasting, two-way broadcasting, high definition (HD) broadcasting, and broadcasting using IP (IPTV) are simultaneously implemented. This situation is not utilized. IPTV, which can accommodate all of the above-mentioned broadcasting methods, has limitations in that bandwidth is overlapped by using bandwidths other than the frequency bandwidths of analog broadcasting and digital broadcasting that are currently transmitted, and it cannot use the advantages of existing technologies.

In other words, IPTV does not use the existing airwave broadcasting band but uses a separate band, which is far from the efficient use of radio resources.

In addition, if you want to know the relevant information while watching the broadcast, you can easily know the information provided by the provider with the simple operation of the remote control, and it is possible to store and utilize the information. There is a problem that there is no continuity and simplicity of information acquisition and cannot concentrate on watching a broadcast because of searching, so that the impression of viewing is inferior.

This problem will be described with reference to FIG. 1 in the conventional broadcasting system.

1 is a block diagram showing a conventional broadcast data providing system.

Referring to FIG. 1, the broadcaster 100 transmits broadcast data, that is, a query linked to the broadcast content, when the broadcast content is transmitted to the terminal 110. Briefly, the query is mentioned in the background, but while watching the news, the broadcast content is news, and the query is a profile of the announcer who conducts the news. When the viewer selects the announcer, the viewer can check information such as the announcer's profile, the announcer's clothes and accessories, and the price.

Therefore, the conventional broadcast data providing system can be said that the broadcasting station unilaterally transmitted the query together with the broadcast data, and if there is information that the user wants to know more, there is a problem of separately searching through the Internet or various media.

Accordingly, an object of the present invention is to provide a user with an expected query list by searching and processing broadcast data in advance in a separate server.

In addition, by utilizing the existing broadcasting bands such as the existing over-the-air, cable, and satellite broadcasts, the user can use the IP communication to provide the user's request query and provide additional services that are interoperable with it, thereby increasing the utilization of limited radio resources and increasing the IP bandwidth. The purpose is to reduce unnecessary use.

The broadcast data providing method and system therefor according to the present invention deliver the expected query desired by the user while using the existing broadcast system as it is, and the user can reduce the unnecessary search time for the interest information while watching the broadcast by using the expected query. It has an effect.

According to an aspect of the present invention, there is provided a method of providing broadcast data between a server and a terminal, the method comprising: a first step of the server and the terminal receiving broadcast data from a broadcasting station; Analyzing, by the server, broadcast data, and generating a user expected query list based on broadcast channel information and transmitting the same to a user terminal; The third step of receiving the expected query list in the terminal to notify and display the list on one side of the screen.

In addition, the broadcast data providing system according to the present invention includes a broadcast data providing system between a server and a terminal, comprising: a broadcasting station for transmitting broadcast data; A terminal for receiving broadcast data from the broadcast station and displaying the broadcast data on a screen; And a server for receiving broadcast data from the broadcast station, analyzing and processing broadcast data, and transmitting a user expected query list to the terminal.

The above objects, features and advantages will become more apparent from the following detailed description taken in conjunction with the accompanying drawings. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

2 is a block diagram showing a broadcast data providing system according to the present invention.

Referring to FIG. 2, the broadcast station 200 transmits broadcast data.

The server 210 receives broadcast data from the broadcasting station 200, analyzes and processes the broadcast data, and transmits a user expected query list to the terminal 220.

The terminal receives the broadcast data from the broadcast station 200 and expresses the broadcast data on the screen.

Looking at the transmission procedure of the broadcast data briefly, unlike the existing system, in the present invention, the broadcast station 200 simultaneously transmits broadcast data to the server 210 and the terminal 220. The broadcasting station 200 includes a terrestrial broadcasting station, a comprehensive cable broadcasting station, and a satellite broadcasting station. The server 210 refers to an information provider, and analyzes the broadcast data received from the broadcasting station 100 to prepare a user expected query list. Since the terminal 200 receives the same broadcast data, the server 210 analyzes and processes a query determined to be desired by the user based on the broadcast data. When the thus-produced user prediction query list is transmitted to the terminal 220, the terminal 220 displays the reception of the user prediction query list on the screen of the connected A, B, .... N device at the same time as the notification.

Preferably, the terminal 220 refers to a set-top box.

More preferably, the A, B and N devices refer to a terminal having a screen, and a representative example may be a TV.

3 is a diagram illustrating a configuration of a method for providing broadcast data between a server and a terminal according to the present invention.

Referring to FIG. 3, the left side shows the configuration diagram of the server 210, and the right side shows the configuration diagram of the terminal 220.

The broadcast data from the broadcasting station 100 (not shown) is received at the server 210 and the terminal 220, respectively. Preferably, the tuner 221 of the server 210 receives broadcast data.

The wireless unit 222 transmits broadcast channel information to the server 210 and receives a list of expected queries sent from the server 210.

The memory 223 receives and stores the expected query list.

The controller 224 selects and outputs an expected query such as a channel currently being reproduced from the expected query list on the screen.

Preferably, the wireless unit 222 is an IP communication port for IP communication.

The wireless unit 211 of the server 210 receives broadcast data from a broadcasting station, and stores the broadcast data in the memory 212. The controller 213 analyzes and processes the broadcast data to generate a user expected query, and transmits the expected query list to the calculator terminal 220 through the wireless unit 211.

Preferably, a push technique is used when the server 210 transmits the expected query list to the terminal 220.

Meanwhile, the controller 224 of the terminal notifies the reception of the expected query list to one side of the screen in the form of a ticker or an image.

In addition, when receiving the expected query list from the server 210, the controller 224 selectively displays the query on the screen according to a preset user preference.

That is, since the favorite genres of sports, movies, dramas and the like are different according to individual preferences, queries related to the genres are selectively displayed on the screen when a broadcast program is played.

Also, if the terminal having the screen is turned off, the controller 224 stores the expected query list in the memory. If the terminal having the screen is turned on, the controller 224 determines whether the stored expected query list is the latest list to determine the latest query. To be updated and displayed.

That is, when the power of the terminal having a screen connected to the set-top box is turned off, the expected query list is stored in the memory 223, and when the terminal is powered on, the expected query list stored in the memory 223 is displayed. As time passes, it is determined whether the list is the most recent list. If not, the list is updated with the latest query and displayed.

4 is a flowchart illustrating a broadcast data providing method according to the present invention.

Referring to FIG. 4, the broadcast station 100 transmits broadcast data to the server 210 and the terminal 220.

Preferably, the server 210 refers to a separate information provider, and the terminal 220 is a set-top box with a built-in TV tuner and an IP connection port.

The server 210 analyzes broadcast data received from a broadcast station (S401). The broadcast data is broadcast media such as news, movies, and sports. The user anticipated query list is created using the analyzed data (S402). The user prediction query is information required to be desired by the broadcast viewer, and may be, for example, actor information in a drama, information of a product worn by the actor, and a drama plot. Not only the drama but also the food program, it can be a food restaurant or a cooking method. Therefore, the server 210 sets and retrieves arbitrary rules because the types of queries are huge.

That is, when the server transmits the expected query list to the terminal, the user priority is selectively set.

Preferably, the user priority includes at least one of viewer ratings and preferences of broadcast data. For example, if teens prefer music programs, 20s movies, and 30s dramas, priority is given to queries corresponding to genres suitable for each age group.

On the other hand, when the server transmits the expected query list to the terminal by using a push technique (S403).

Preferably, the server uses IP communication when sending a list of expected queries to the terminal.

In addition, the server retrieves the expected query list corresponding to the broadcast data in real time or in advance and transmits it to the terminal.

Basically, when broadcasting data is received from a broadcasting station, data of at least one broadcasting channel is analyzed. For example, if the data of the broadcast channel of 10 channels is received, the server analyzes the broadcast data of all 10 channels and a query determined to be desired by the user. This is how you search in advance. However, this preliminary search narrows down the query analysis you want. A more accurate analysis method is a real-time search, which is provided only when there is a step of transmitting the broadcast channel information currently playing in the terminal to the server with the consent of the user. When a viewer requests a query related to channel 1 to the server while watching a broadcast, for example, a channel 1 broadcast, the server analyzes the broadcast data for only one channel, so that the user can perform the expected query. You can analyze it more accurately.

In addition, if the broadcast channel information currently being played is transmitted to the server, it may be used for the audience rating survey. However, if personal information is not agreed, it will not be transmitted.

The terminal receives the user prediction query list transmitted from the server and notifies and displays the prediction query list on one side of the screen.

Preferably, after receiving the expected query list, the query list of the same channel as the broadcast channel currently being played is selected. This is because the server does not analyze data of only one broadcast channel, but analyzes and processes at least one broadcast data to create a user expected query list. Therefore, the terminal displays a query of the same channel as the channel that the viewer is currently watching on the screen.

In addition, after receiving the expected query list, when the terminal, that is, the terminal having a screen connected to the set-top box by wireless or wired is turned off, the expected query list is stored in the set-top box.

Preferably, the terminal provided with the screen is a terminal provided with a liquid crystal or CRT, such as a TV, a monitor.

In addition, when the terminal having the screen is turned on, it is determined whether the expected query list stored in the set-top box is the latest query, and the query is updated and displayed.

That is, when a user expectation query list is received from the server, the screen should be displayed on the screen. If the terminal having the screen is turned off, it cannot be displayed. Therefore, when the terminal having the screen is turned on, it is determined whether or not the user expected query list temporarily stored in the set-top box and the currently playing broadcast program correspond to the latest query and re-receives and updates the query.

Preferably, when displaying the user prediction query list on the screen, the reception of the prediction query list in the form of a ticker or an icon on one side of the screen.

5A to 5D are diagrams illustrating one embodiment of a broadcast data providing method according to the present invention.

Before describing FIGS. 5A to 5D, the server will be described by taking an example of real-time search without analyzing broadcast data in advance. In other words, when a user requests a real-time search.

If a user wants to see information while watching a broadcast program using the set-top box, the user presses an arbitrary key and requests a query of the broadcast channel currently being viewed (FIG. 5A).

The server searches and processes the expected query list desired by the user according to the user's request based on the broadcast channel information, and transmits the expected query list in the form of a ticker or an icon to one side of the screen. 5b).

In addition, if the profile of the announcer is curiously selected while watching the news (FIG. 5C), the profile of the announcer is displayed on one side of the screen (FIG. 5D). Therefore, the user can request the server to check if there is desired information while watching a broadcast program, thereby reducing the inconvenience of searching separately.

The present invention described above is capable of various substitutions, modifications, and changes without departing from the spirit of the present invention for those skilled in the art to which the present invention pertains. It is not limited by the drawings.
