| 抄録(英) | Mobile Broadcasting Corporation will launch the World's first multimedia mobile broadcasting service in Japan in 2004. The service is Satellite Digital Broadcasting services for mobile and personal users by use of 2.6GHz radio frequency band. This service consists of a large number of various multimedia broadcasting programs such as high quality digital audio programs, video programs and also data transmission is able to be received with vehicular and small portable receivers in mobile environment. In order to realize this service, a geostationary satellite with high power transponders and a high gain large deployable S-band antenna of 12-meter in diameter is used. Terrestrial repeaters, called Gap Fillers, which transmit broadcasting signal to the areas where the satellite signal is blocked by obstacles such as in the areas of high tall buildings in the Metropolitans, tunnels, and subways, are also used. In this paper, recent development status of the system is described in addition to the verification tests including field tests to evaluate the system performance. |
