With the development of information and communication, distribution, and culture, society has gradually evolved into a population-intensive metropolis, and public places such as subway stations, train stations, shopping malls, and performance halls are increasing. As the public crowds in public places, efforts have continued to provide information and entertainment to the public. One such effort is to install video media such as CRTs and LCD screens in subway stations, train stations and subways. Video media output news, weather, movies, dramas and music videos for citizens who use public spaces. Citizens who use public places can look at the printed screens to get useful information or relieve boredom from long trips.

1 is a view showing a video medium installed in the subway.

When video media is installed at a suitable place inside the subway for people to watch, people using the subway can selectively view the installed video media. However, in general, a video medium of a public place provides only video content, but only audio content having a very small size even if it does not provide or provides audio content. Since public places are used by many people of various tastes, it is difficult for everyone to be satisfied with listening to the audio contents provided with the video contents. Because I can give. As a result, people who want to listen to the voice content may not be able to listen to the voice content without overcoming the spatial constraints of public spaces.

On the other hand, with the recent development of computer and communication technology, various wireless communication services using a wireless communication network have been provided. The most basic wireless communication service is a wireless voice call service that provides a voice call to a mobile terminal user wirelessly, which can provide a service regardless of time and place. In addition, while providing a text message service to complement the voice call service, a wireless Internet service has recently emerged to provide an Internet communication service to a user of a mobile communication terminal through a wireless communication network.

In order to provide such a service, a mobile communication system has been developed through a first generation analog AMPS (Advanced Mobile Phone System) system and a second generation cellular / personal communication service (PCS) system. The IMT-2000 (International Mobile Telecommunication 2000), which is a third generation mobile communication system established by ITU-R as a standard, is commercially available.

IMT-2000 is supported by existing IS-95A, IS-95B, and IS-95C networks, for example, Code Division Multiple Access (CDMA) 2000 1x, CDMA 2000 Evolution Data Only (EV-DO), Wideband CDMA (WCDMA), etc. It is a system that can service data communication at a speed faster than the data transmission speed. In particular, using the IMT-2000 system, it is possible to provide various multimedia services at a higher speed as well as to improve the quality of services using the existing voice communication service and WAP (Wireless Application Protocol).

Here, the CDMA 2000 system is a mobile communication system synchronously implemented in the IMT-2000 system, and is divided into 1x and 3x according to the number of FAs used as carriers. In addition, there are various technology schemes such as 1x EV-DO and 1x EV-DV according to the evolutionary contents. Accordingly, the CDMA 2000 system can be classified into a CDMA 2000 1x, a CDMA 2000 EV-DO (or EV-DV), and a CDMA 2000 3x system according to the number and evolution of FAs. As such, the CDMA 2000 system is a concept encompassing a system implemented by various technical methods. In addition, the WCDMA system is a mobile communication system asynchronously implemented in the IMT-2000 system. The wireless access method for communication between the base station and the mobile terminal uses the CDMA method, but the mobile communication network technology is GSM (Global System for Mobile Communication). Based on network technology. The WCDMA method does not need to use Global Positioning System (GPS) to synchronize the entire base station, supports international roaming service, widens the frequency bandwidth to 5 MHz, and has a data transmission rate of 2 Mbps, which is suitable for high-speed data transmission. Do.

However, the existing mobile communication system has a limitation in providing high-speed wireless Internet due to high base station construction cost and high usage rate of the wireless Internet, and a limited screen size of the mobile communication terminal. Wireless Local Area Network (WLAN) technology has limitations in providing air services due to problems such as radio wave interference and a narrow coverage area. Accordingly, a portable Internet system that can use a high-speed wireless Internet service at a low rate while moving has emerged.

The portable internet system uses various types of portable terminals such as laptops, PDAs, and handheld PCs to access various types of information and contents by accessing the Internet in indoor and outdoor stationary environments and mobile environments at walking speeds and low to medium speeds. It is a service. In addition, it provides mobility of 60 km / h per hour, provides downlink transmission speed of 24 Mbps, and can provide downlink transmission speed of 50 Mbps by applying Multiple Input Multiple Output (MIMO) system. Wireless data system. In addition, the portable Internet system uses a 2.3 GHz frequency band, draws a time division duplex (TDD) by a duplex method, and uses multiple access to effectively use the allocated frequency spectrum. Orthogonal Frequency Division Multiple Access (OFDMA) is used as a scheme.

The wireless Internet service or the portable Internet service using the above-described mobile communication system provides a short message service (SMS), a multimedia streaming service (SMS), etc. to a mobile communication subscriber. Here, the short message service is a two-way data radio call service, and is a service that allows a mobile terminal or a network to exchange messages composed of letters and numbers. In addition, the multimedia streaming service is a service that transmits and plays multimedia contents such as voice, video, and animation to a mobile communication terminal in real time. Instead of downloading and playing a file, the multimedia streaming service simultaneously downloads and plays a standby time for playback. It is unnecessary and is not limited by the amount of storage space.

Although the mobile subscriber receives a multimedia streaming service using a mobile communication terminal, a typical multimedia streaming service downloads and plays voice, video, and animation provided by a specific content provider as a whole. Accordingly, there is no service for allowing mobile communication subscribers to download and play voice content corresponding to the video content in real time using a mobile communication terminal, among broadcast contents broadcast in a video medium provided in a public place.

 In order to solve this problem, the present invention provides a short text inputted by a mobile communication terminal to input a unique number of a video content in order to receive and reproduce voice content corresponding to the video content in real time during a broadcast provided through a video medium installed in a public place.
