The media playback apparatus 140 may re-receive the content from the service server 100 through the satellite broadcast network 115 when it is determined that the media playback apparatus 140 has departed from the satellite gamut area.

If the content requested by the user is identical to any one of a plurality of contents cached by the caching server 150, the media playback apparatus 140 may provide the caching server 150 with caching information corresponding to the content requested by the caching server 150 Content can be received. Here, if the content is not cached in the caching server 150, the content may be cached in the caching server 150 for a predetermined period.

That is, the media playback apparatus 140 switches the service mode to the service server 100 by switching the satellite mode using the satellite broadcast network 115 or the backup mode using the mobile communication network based on whether the media playback apparatus 140 has entered the satellite- It is possible to receive continuous contents from the server.

The caching server 150 may be a portable caching server installed in the premium bus 130. If the content is not cached, the content server 150 may cache the content for a preset period of time.

The caching server 150 may receive a request for content from the media player 140 according to whether the media player 140 enters the satellite transliteration area. When the media playback apparatus 140 corresponds to any one of a plurality of media playback apparatuses installed in the premium bus 130, the caching server 150 may further include a caching server 150 based on the satellite signals changed as the premium bus 130 moves The user can be requested for the content from the media player 140 according to whether the media player 140 enters the satellite transliteration area. The entry of the media playback apparatus 140 into the satellite transliteration region may be determined based on the satellite signal for the content transmitted from the service server 100 to the media playback apparatus 140 via the satellite broadcasting network 115 .

The caching server 150 can receive the content requested from the service server 100 through the mobile communication network 125. [

The caching server 150 may provide the received content to the media player 140. [ For example, when the requested content is identical to one of a plurality of contents cached in the caching server 150, the caching server 150 provides the cached contents to the media playback apparatus 140 in response to the requested content . For example, when content identical to any one of a plurality of contents cached in the caching server 150 is requested through at least one other media playback apparatus 140 among the plurality of media playback apparatuses 140, The content cached in the caching server 150 may be provided to other media playback apparatuses.

The mobile communication modem 160 can receive content from the service server 100 through the mobile communication network 125 and transmit the content to the media playback apparatus 140.

The mobile communication network 125 has a first frequency (bandwidth: 20 Mhz) of 1.8 GHz, a second frequency (bandwidth: 10 Mhz) of 900 MHz, a third frequency (bandwidth: 10 Mhz) of 2.1 Ghz, (Bandwidth 10 Mhz), and the media playback apparatus 140 may receive the content through Long Term Evolution (LTE) Internet communication over the first frequency. For example, the maximum Internet communication speed of one radio frequency is 150Mbps, and Carrier Aggregation (CA) technology, which combines two or more frequency bands together to allow a wider bandwidth, Can be increased. For example, bundling two radio frequencies with carrier aggregation technology can speed up to 225Mbps, bundling three radio frequencies up to 300Mbps, and bundling four radio frequencies up to 375Mbps.

The reason for using carrier aggregation is that media video contents have a large transmission rate of at least 2 to 10 Mbps, and when there are many users connected to peripheral base stations, the line speed rapidly decreases, Thereby ensuring the quality of the content providing service.

For example, when two frequencies are combined using carrier aggregation (CA), a transmission speed of up to 225 Mbps is obtained. Thus, when the moving image transmission amount is 10 Mbps, As shown in FIG.
