A method for controlling the code rate of the stream media includes the following steps: determining whether to regulate the stream media code rate sending to a user terminal according to the network status fed back by the user; when it needs to be regulated, determining the adaptation parameter; performing the adaptation process for the stream media code rate according to the adaptation parameter; sending the adaptation processed stream media to the user terminal. The present invention also provides a system and device for controlling the code rate of the stream media. The code rate adaptation server performs the code rate adaptation of the stream media required by the stream media server, it only needs to store the chip source according to single code rate on the stream media server, saves the memory space on the stream media server, and reduces the coding complexity of the stream chip source. |
