The design scheme of streaming media system based on multiple 3G cards in mobile network

The paper designs the system of real-time streaming media transmission based on multiple 3G-card in the mobile environment especially for news workers to report news events quickly and duly. The paper introduces the system framework including 3 big modules: capturing and transportation subsystem, multiple 3G cards controlling subsystem and media receiving subsystem. Among them transmission and 3G controlling subsystem and quality of service is the key technology of the real-time transmission system. The paper adapts popular compressing algorithm, H.264 for video and AAC for audio. In order to ensure the real time and quality of the streaming media, it adapts the Matron card to capture and compress the media streaming and multiple 3G cards to add the network bandwidth.
