INTERACTION SYSTEM AND METHOD FOR MOBILE MULTIMEDIA BROADCAST

摘要

An interaction system for mobile multimedia broadcast is provided in the present invention; the system includes a mobile multimedia broadcast (CMMB) service and interaction control device; via a bidirectional network, the CMMB service and interaction control device is used to receive, from a CMMB terminal, an interaction service request information carrying a service requested by a CMMB terminal, and used to according to the interaction service request information, transmit a service content requested by the CMMB terminal to the CMMB terminal via a CMMB broadcast network. In the present invention, an uplink network loop of the bidirectional network is used to provide an interactive on-demand function for the CMMB broadcast network, thus the cost for establishing the network is saved and the utilization rate of the broadcast network is improved. At the same time, an interaction method for multimedia broadcast is also provided in the present invention.
