The present invention relates to a location-based video content service system and a method of providing the same through an image output device (display device).

In connection with the present invention, a conventional positioning technology for a location based service (LBS) is divided into a cell method using a mobile communication base station and a GPS (Global Positioning Service) method using a satellite. A hybrid method that combines cell and GPS methods was introduced.

In brief, the cell method is a method of measuring the position of the subscriber using a method such as triangulation based on the base station connected to the mobile subscriber, even in a city with many base stations, the position is confirmed with an error of approximately 500 to 1500 m. As a result, the error range is wide, and thus only a rough position can be detected. In the case of the GPS method, the satellite tracks the position of the GPS chip embedded in the mobile communication terminal to find a relatively accurate position within a 10 to 150 m error.However, due to the characteristics of the satellite signal, it cannot be used indoors. This has the disadvantage that it is well vulnerable to high-rise buildings. In addition, even in the hybrid method, although the shortcomings of the two measurement methods are compensated for, the maximum precision of the positioning technology has the limitations of the GPS method.

Therefore, in the case of the conventional location-based service, it is possible to grasp the approximate location of the subscriber having the mobile communication terminal, but it is difficult to more accurately identify the location (for example, within 10 to 20m), and also share the video output to the subscriber. There is no service that provides location and personalized video content through the device.

The present invention has been made to solve the problems of the prior art as described above, the object of the present invention is to measure the position of the mobile communication terminal more precisely by using a short-range wireless communication technology, preferably Zigbee (Zigbee) technology In addition, the present invention provides a location-based video content service system and a method for providing personalized video content based on the measured location.

In detail, the area display signal generator 110 generates a beacon signal including the location identification information. The location identification information is information for identifying the location of the area display signal generator, and may use a unique number of the area display signal generator or location information on which the area display generator is installed. In case of using the unique number of the area display signal generator (eg, the serial number of the device), the information on the location where the area display signal generator is installed in the location information management server 150 should be registered in advance. Even if location information is used, the location information management server 150 or the like should be able to interpret the contents.

The beacon signal transmitted from the area display signal generator 110 is a signal for guiding position measurement, and uses a short range wireless communication technology having a narrow range of beacon signal for accurate position measurement, and preferably Zigbee. Take advantage of wireless data network technology.

Zigbee is one of the IEEE 802.15.4 standards supporting near field communication. It performs near field communication within 10 to 20 meters in wireless networking in homes and offices, and it is different from other wireless communication technologies such as IEEE 802.1 or 802.15. Otherwise, this technology is suitable for the small size, low power, and low price market where simple functions are required. In addition, Zigbee can combine transceivers with sensors (motion, light, temperature, temperature, humidity, etc.) to form a large sensor network, using three frequency bands for transmission rates from 20 to 250 Kbps up to 100M. It supports up to 255 devices in one wireless network at 2.4GHz, and expands up to 65,000 nodes.

Meanwhile, a location-based video content service subscriber having an area display signal receiver 120 refers to a communication area of the area display signal transmitter (that is, an area capable of receiving a beacon signal), hereinafter for convenience of description. The area display signal receiver 120 receives the beacon signal, and transmits the location identification information to the mobile communication terminal 130. In this case, the area display signal receiver 120 may be connected to the mobile communication terminal by a connection cable or may be provided inside the mobile communication terminal as a built-in type.
