| Abstract: | A multi-channel live video scheme based on hybrid cloud storage has been presented in the paper,one of its purpose is to solve problems in the multi-channel live video system,which are user start delay,playback lag,channel switching perturbation and so on,and the other is to reduce the cost caused by deploying a large number of video servers in order to meet the needs of large-scale users.The scheme designs the application layer network structure among public cloud server,private cloud server and the users,and it also introduces the P2P technology to enhance the cooperation function of the live broadcast system,and last the server selection and the bandwidth allocation model is constructed.The implementation data reveals that the plan can improve system service capabilities and improve live video quality. |
