A method for reducing times of receiving overhead information by a mobile multimedia broadcast terminal, comprising the following steps: a mobile multimedia broadcast system multiplexes different services according to service type, generates different overhead information, and adds an overhead information update indication in a corresponding service data segment for indicating whether the overhead information in the next frame will be updated; a receiving terminal monitors whether the overhead information will be changed according to the overhead information update indication in the service data segment; when the overhead information update indication indicates the overhead information in the next frame will not be updated, the receiving terminal will not receive the overhead information and only receive necessary service data in the next frame; when the overhead information update indication indicates the overhead information in the next frame will be updated, the occurrence of the update will be recorded, and the receiving terminal will determine whether to read the updated overhead information according to whether it is necessary to receive other services other than the current service. |
