Bi-directional stratosphere satellite DMB repeater apparatus and its method

摘要

1. The art that the invention defined in the claims ; The present invention relates to a two-way stratosphere will satellite digital multimedia broadcasting (DMB) relay apparatus and a method thereof. ; 2. SUMMARY ; The present invention is invented to solve this by using a two-way satellite DMB stratospheric relay placed in the stratosphere, satellite DMB satellite is not only possible to take advantage of the general broadcasting and communications geostationary satellite and the user Digital multimedia application specific locations in order to transfer the center of the satellite DMB (DMOD: Digital Multimedia on Demand) for providing a two-way interactive stratospheric satellite DMB service and satellite DMB services, such as access point and its object is to provide a method that. ; 3. Solution subject matter of the invention ; The present invention, located in the stratosphere, and the geostationary satellite DMB service between the ground terminal to the satellite DMB interactive stratospheric satellite digital multimedia broadcasting (DMB) relay apparatus for relaying In the geostationary-satellite and satellite signal (C-band, Ku-band or Ka band), the first receiving means to send and receive; Down-DMB relay means for down-conversion and amplification in the first receiving means is capable of receiving the satellite DMB signal is a satellite signal to the satellite DMB terminal received from the geostationary satellite (L-band or S-band); A second transmitting and receiving means for sending and receiving the satellite DMB and satellite DMB signal terminal (L-band or S-band) for; And the second transmitting and receiving means up to the up-conversion and amplification to the signal to the geostationary satellite is received, the order of the satellite DMB signal received from the satellite DMB user terminal (C-band, Ku-band or Ka band) DMB including the relay means. ; 4. An important use of the invention ; The present invention provides satellite and satellite communications systems and yiyongdoem.
