Abstract

Embodiments of the present invention provide a transmission data method for Digital Multimedia Broadcasting (DMB). The method comprises the following steps: generating the transmission data frame allocation information in the DMB sending end, and sending the transmission data frame allocation information to the DMB receiving end. According to the transmission data frame allocation information, the DMB receiving end selectively receives traffic data from the DMB sending end. Embodiments of the present invention also provide a transmission data system for DMB, a sending end and receiving end for DMB. The working power loss of receiver is decreased by applying embodiments of the present invention.

Description

technical field [0001] The present invention relates to the technical field of digital multimedia broadcasting, in particular, the present invention relates to a method, device and system for transmitting data in digital multimedia broadcasting. Background technique [0002] Digital Multimedia Broadcasting (Digital Multimedia Broadcasting, DMB) is a new concept multimedia mobile broadcasting service that integrates communication and broadcasting. In addition to supporting traditional audio broadcasting, this technology will also be able to transmit various multimedia information such as traffic information and news to mobile terminals through MPEG-4H.264, MPEG-2, AAC+ and other methods, providing high-quality Quality sound quality and diverse data services. [0003] The biggest feature of digital multimedia broadcasting is that it is broadcast, point-to-multipoint, point-to-face, and the cost of broadcasting information has nothing to do with the number of users. Therefore...
