DATA DISTRIBUTION DEVICE AND TRANSMISSION METHOD |
摘要 |
<p>A server (191) transmits image information consisting of basic data and complementary data to a router (100) through the Internet (192). The router (100) allocates the basic data to a BS (110) of a cellular system (193) and the complementary data to an AP (120) of a wireless LAN system (194). The BS (110) transmits the basic data to a MS (150) and the AP (120) transmits the complementary data to the MS (150). When the MS (150) is located in the area of the cellular system (193), the MS always maintains a communication channel with the BS (110) and when the MS enters the area of the wireless LAN system (194), the MS also opens a channel with the AP (120) while maintaining the channel with the BS (110) . This allows the user to continue seamless communication. <IMAGE></p> |
