Live video sharing is a newly generated and interesting service, with which users can broadcast and view the videos being recorded by mobile phones. However, mobile network usually blocks users to enjoy that service since video transmitting is still a nontrivial task with poor bandwidth. In order to make live sharing easier in mobile environment, a novel service with multimodal modes is proposed in this paper, which could save a lot of bandwidth for sharing and is more adaptive in mobile network. To save bandwidth and introduce differentiated user experience, real-time extracted key-frames, audio or hybrid information can be transmitted instead of original video stream. Both publishers and receivers can select suitable mode according to their preference or network condition. Thanks to the key frame mode of the proposed service, detailed tagging of video content and live cooperation with other SNS can be implemented. Experimental results and user study demonstrate that the proposed multimodal live sharing service is of high adaption of mobile network and introduces direct and interesting user experience.
