  • Content distributing system and content distributing method
    Patent number: 7764636
    Abstract: A content distributing system wherein the reliability of receiving content data in wireless sections is improved to realize a more reliable content data distribution. When performing a data download communication (e.g., MBMS communication mode) using a multicast, a distribution managing apparatus (102) produces and broadcasts an MBMS communication mode initiation instructing signal to each of mobile terminal apparatuses (104). In response to the MBMS communication mode initiation instructing signal, the mobile terminal apparatus (104) stops another currently running application program and initiates the MBMS communication mode. In this way, the mobile terminal apparatus (104) can use sufficient resources to execute a multicast data download communication mode, so that it can receive the broadcasted contents without fail.
