The present invention relates to a DMB system having a download service function using index information.

More specifically, if a student has a question during learning using a DMB terminal equipped with a program for selectively downloading the learning contents using the index information, simply input the index information. The present invention relates to a DMB system having a download service function using index information for selectively downloading and learning content.

DMB is a mobile multimedia broadcasting that can enjoy high quality voice (radio) and video service (TV) while moving. Promoted for the digitalization of radio, speed of about 380kbps is possible, so it can provide video service.

TV receivers could be installed in some conventional cars, but the problem of being stuck or interrupted due to poor radio wave reception rate is now being pursued by DMB. The DMB currently being tested is able to watch high-definition broadcasts without interruption.

DMB can be broadly divided into satellite DMB and terrestrial DMB, as shown in FIG. The terrestrial DMB is to catch and watch radio waves emitted from a transmission station like a general TV, and the satellite DMB is a method of spreading radio waves throughout the country through satellites.

The terrestrial DMB delivers various contents such as music, text, and video through portable terminals such as small TVs and PDAs with excellent mobile reception characteristics, and establishes a complementary relationship with digital terrestrial TV broadcasting to be combined with mobile communication terminals. Services can create breakthrough demand.

The satellite DMB provides a multimedia broadcasting service including audio and additional data or video to a fixed, mobile, and portable receiver through a satellite. The satellite DMB provides various quality audio broadcasting services at low cost and uses a satellite to cover a large area. Coverage can dramatically expand the audible range of existing broadcasts.

The difference between the terrestrial DMB and satellite DMB is the same as the difference between general TV broadcasting and satellite TV broadcasting. In other words, terrestrial DMB can be viewed without paying, but satellite DMB has to pay a certain amount due to the satellite fee. In addition, satellite DMB has dozens to hundreds of channels while terrestrial waves have a limited number of channels.

In other words, satellite broadcasting transmits a video and audio signal produced by a broadcasting station through a transmitting earth station and transmits a signal to a receiving earth station in a distant place using a satellite, which is a low-orbiting satellite, as a repeater. The signal is transmitted to the satellite and the transmitted signal is received by the satellite and downstream through the S-band of 2GHz to 4GHz. Meanwhile, terrestrial broadcasting transmits video and audio signals produced by a broadcasting station to a repeater, and the transmitted video signals and the like are downstream through the L-band.

According to current technology progress, people will be able to enjoy high-definition broadcasts on HD TV at home, and watch DMB while on the go, that is, when driving in a car or watching on a PDA.

In case of learning by downloading the learning contents using the DMB terminal that can receive the DMB data as described above, when the time required for downloading is longer, the battery consumption increases and the battery is easily discharged and the downloaded learning contents are downloaded. The problem is that you can't learn as soon as possible.

The present invention has been made to solve the above problems of the prior art, an object of the present invention is to provide a student using a DMB terminal equipped with a program to selectively download the learning content using the index information If there is a question in the middle of learning to provide a DMB system having a download service function using the index information to be able to selectively download only the desired learning content by simply entering the index information.

In addition, an object of the present invention is to provide a DMB system having a download service function using the index information to minimize the battery consumption by selectively downloading only the desired learning information.

In addition, an object of the present invention is to estimate the user's undergraduate subjects using the learning information downloaded by the user, and to provide supplementary content (problems) using the estimated results to remove the undergraduate subjects of the users. The present invention provides a DMB system having a download service function using index information.

In addition, an object of the present invention is to create a learning status information using the learning information downloaded by the user and provide the generated learning information to the parents or teachers instructor to provide an appropriate learning program to enhance the learning effect It is to provide a DMB system having a download service function using.

An embodiment of the present invention proposed to solve the above technical problem, in the DMB system for transmitting DMB data and various contents produced through the DMB broadcasting system and DMB data communication network, desired learning using index information Provides learning service items that can download and view only information. When the user selects the learning service items, the user can input index information, and request and download the learning information corresponding to the input index information. A DMB terminal providing an output interface screen; And a learning information DB storing index information and learning information matching the index information, receiving index information from the DMB terminal through the DMB data communication network and a DMB broadcasting system, and reading the corresponding learning information from the DB to read the DMB data. Characterized in that the learning information supply server including a learning information management module for transmitting to the DMB terminal via a communication network and DMB broadcasting system.

Hereinafter, a DMB system having a download service function using index information will be described in detail with reference to the accompanying drawings.

DMB system having a download service function using the index information implemented by the present invention is a DMB terminal 100, DMB data communication network 300, learning information supply server 200, DMB broadcasting as shown in Figure 2 Consists of system 400.

The DMB terminal 100 provides a learning service item in which only desired learning information can be downloaded and viewed using the index information downloaded through the DMB data communication network 300, and when the user selects the learning service item, the index is provided. Provides an interface screen (refer to FIGS. 5 to 7) for inputting information, and requesting and downloading learning information corresponding to the input index information and outputting it on the screen.

The learning information supply server 200 is a download information DB (210) for matching and storing the download information collected by the download information collection module 250 to be described later to the identification information of the DMB terminal 100 of the user, The learning information DB 220 storing the index information and the learning information matching the index information, and the DMB terminal 100 when the learning service item is downloaded and mounted on the DMB terminal 100 and the learning service item is updated. Learning information item downloaded to the service information program management module 230 and receives the index information from the DMB terminal 100 through the DMB data communication network 300 and the DMB broadcasting system 400 A learning information management module 240 for reading the corresponding learning information from the DB 220 and transmitting the learning information to the DMB terminal 100 through the DMB data communication network 300 and the DMB broadcasting system 400; When a user downloads the learning information which is composed of download information collection module 250 for collecting the downloaded information.

In addition, the download information collection module 250 transmits the download information collected regularly or irregularly to the learning information management module according to the operation of the operator of the learning information supply server.

In addition, the learning information management module 240 recognizes the subject weakness of the user by using the download information, and transmits training training information that can overcome the weakness of the subject to the DMB terminal 100.
