Description

System and method for providing notification service based on IPTV {SYSTEM AND METHOD FOR PROVIDING NOTICE SERVICE BASED ON IPTV}

The present invention relates to a system and method for efficiently providing a known service such as real-time news breaking by using an IPTV network.

The recent proliferation of broadband media and increased communication speeds have made the Internet a new medium for enabling One source Multi Service. As an example of such a multi-service service, multimedia contents provided by various Internet operators as well as a plurality of airwave TVs and radio channels are provided as a broadcast service through the Internet.

A representative service that emerged from this background is Internet Protocol Television (IPTV) based on Internet Protocol. IPTV is a TV broadcasting service that enables two-way communication through high-speed Internet. It connects a display device and a content providing server on the Internet through a settop box, and provides various broadcast contents and video on demand from the content providing server. (VOD) A service implemented to provide content to a user through a display device connected to a set-top box.

Recently, with the development of the IPTV technology, services provided to users are becoming more diverse. For example, a "notice service" that provides "notice information" such as real-time news breaking news, emergency information or various event news to a user in real time or at regular intervals. Such notification information is mainly text-based data, and a small capacity is generally provided in the form of subtitles.

However, in case of inserting and providing announcement information by overlaying the existing content, an expensive subtitle device is required for each channel in the IPTV headend, and the headend covers the whole country. It is not possible to provide notice information.

In addition, from the point of view of data traffic, if the public IP service is implemented by the general IP method, the user's IP is continuously changed, and in particular, the set-top box at the bottom of the router uses a private IP. Transmission is difficult In order to solve this problem, there is a method of maintaining a continuous connection between the headend and the set-top box by using UDP hole punching method, but in this case, as the number of set-top boxes increases, excessive traffic is concentrated in the central headend. There is a problem that the network performance is degraded.

The present invention has been proposed to solve the above-mentioned problems, and it is possible to reduce the data traffic of the IPTV headend by using a multicast scheme and to provide an optimized notification service to users in each region. It is an object to provide a known service system and method.

The notice information is filtered and transmitted to the user terminal of each local area.

The announcement information is text information including real-time breaking news or urgent information of each region, and may be transmitted as XML data.

The user terminal device may parse the well-known information in the form of text received from the relay server in XML and graphically display it on the user screen.

The IPTV headend divides the notification information provided from the notification operation server by region and stores the notification information as XML data. If the notification information provided from the notification operation server is not XML, the notification information is converted into an XML method. XML conversion unit for converting the data of the data and the data transmission and reception unit for receiving the data from the known operation server and retrieves the data stored in the notification database and transmits to the plurality of relay servers.

The plurality of relay servers may include a user database storing user information of each corresponding region, a filtering unit for filtering only data corresponding to the user information of the notification information, and receiving data from the IPTV headend and receiving the filtered data. It may include a data transceiver for transmitting to the user terminal device.

The user information may include at least one of location information, personal information, a field of interest, and whether to display notice information of each user.

In the IPTV-based notification service providing method according to the present invention, the IPTV headend classifies the notification information provided from the notification operation server by region, and the corresponding IPTV headends are respectively provided by a plurality of relay servers installed in a plurality of regions. Transmitting the announcement information of the region and transmitting the announcement information received from the IPTV headend by the plurality of relay servers to the user terminal apparatus of each corresponding region in a multicast manner.

In addition, when the announcement information provided from the notification operation server is not the XML method, the IPTV headend may further include the step of converting the notification information into XML-type data.

The method may further include parsing XML-based notice information received from the relay server and graphically displaying the well-known information on the user screen.

According to the present invention, by applying a multicast scheme to an IPTV-based known service, data overload of an IPTV headend can be greatly alleviated.

In addition, the relay server of each region serving as a multicast router provides only the filtered information for each user in each region, thereby increasing network utilization efficiency by reducing the size of transmitted data.
