Through the process, the storage cost such as bandwidth, storage cost and the like brought by storing the live broadcast resources into the distributed file system or the database is reduced. Compared with the fixed code rate data packets, the data packets with multiple code rates have the advantages that the cost of storage and bandwidth is multiplied, and the consumption of the part of the data packets stored in the local disk can be reduced. The playing of different code rates can meet the requirements of different definition of audiences. Meanwhile, the live broadcast resources are stored in the local disk, the local disk is accessed faster than the network data, and the precision of live broadcast time delay is improved. The live broadcast resources are stored in the disk instead of the memory, so that the time length of live broadcast delay can be greatly improved. Different streaming protocols have different applicable scenes, so that a user can select the protocol which best meets the service requirements of the user to play.
