| Abstract: | Purpose/significance] Based on virtual learning space and the digital library at home and abroad, this paper analyzes the present situation and development trends of multimedia services integration, and points out the required characteristics and core functions of virtual learning commons under the new circumstances of digital library.Method/process] It designs a new type of virtual learning commons system based on mobile terminal, which fulfills the needs of interactive and fluency through lightweight multimedia data storage and optimized XMPP internet protocol.Result/conclusion] From the angle of software testing results, the stable running system and high efficiency transmission ensure the best usage effect. From the perspective of library, the communication effect of multimedia services by optimizing the transmit audio and video files improves the reading efficiency of audiences, improve the interaction quality of audience information, and plays a better effect on library multimedia information communication. Virtual learning commons relying on new media technology is a breakthrough for the construction of digital library in new era. |
