The combination of CMMB and cellular networks (Joint with Prof. Hui Liu, and Prof. Manyuan Shen)
Figure 1: The system architecture of the converged network.
The hot videos on the Internet can be pushed to mobile terminals via CMMB. When a user wants to watch a video on his/her terminal, our app checks if the very video has been pushed by CMMB. If so, the local video will be played. Otherwise the terminal will play the video on line via cellular networks such as 3G or LTE. For the case that the file of video received through CMMB is corrupted, only the lost data segments will be downloaded through cellular network, and thus the data traffic is saved. It can be expected that the combination of CMMB and cellular networks can improve user experience significantly.
