If the multimedia data is transmitted from the mobile terminal 600 and the multimedia data, that is, the content data is transmitted from the data center 300, the multimedia data is received and stored in the storage unit 223 and the other devices 240. By transmitting the content, the corresponding content may be stored in the other device 240 or played back through the other device 240. That is, although the multimedia service is requested by the mobile terminal 600, the content may be directly transmitted to the other device 240 instead of the mobile terminal 600, so that the multimedia service may be played on the other device 240.

As described above, in the embodiment of the present invention, the mobile terminal 600 located in the vehicle 20 is connected to the lamp 230 via visible light communication, and the headlamp connected to the data box 220 controlling the lamp 230. Since it may be connected to the multimedia center 100 through the visible light communication performed by the 120 and consequently the data center 300, the multimedia service provided by the data center 300, that is, the content may be provided at a high speed. There is a number. For example, since the mobile terminal 600 located in the vehicle 20 can receive contents through visible light communication having a transmission rate of 100 Mbps to 1 Gbps, the movie (about 700 MB) can be shortened from several seconds to ten seconds. You will be provided through time. Therefore, the vehicle 20 may be provided with a large amount of content even through a short stop at the place where the multimedia center 100 is located, for example, a gas station.

However, in the visible light communication method, the transmission efficiency may be deteriorated when the interference light is affected. Therefore, a technique that cuts the interference light so that it can be transmitted while blocking the interference light at a shorter distance and closest to the maximum, for example, diversity, cancellation, and guard interval insertion Interval Insertion) and Equallizer allow for maximum transmission efficiency.
