Abstract

Embodiments of the present invention disclose a processing method, distribution server, client and system for streaming media. The method comprises: receiving content segment request information sent by a client; acquiring resource information of a wireless network where the client is located; predicting a data transmission rate of the wireless network according to the resource information; selecting a content segment matching the data transmission rate; and sending the content segment to the client. In embodiments of the present invention, a distribution server predicts the data transmission rate of the wireless network where the client is located and further selects the content segment with a bitrate matching the data transmission rate for the client, thereby making the bitrate of the content segment sent to the client more appropriate, realizing overall regulation of the bandwidth condition of the cellular wireless network, stable reduction of network congestion, and solving the problem of network congestion.
