description The embodiment of the invention discloses a code rate adjustment method and a server, which are applied to the technical field of communication. The code rate adjustment method comprises the following steps that: a packet-switched streaming server (PSS) acquires at least two broadband quality parameters according to a received receiver report, obtains at least two pieces of code rate adjustment information corresponding to the obtained at least two broadband quality parameters according to the corresponding relation between preset broadband quality parameters and the code rate adjusting information, and performs code rate switching adjustment. In the code rate adjustment method, the actual fluctuation situation of a network bandwidth is determined according to more than two indexes. Compared with determining the actual fluctuation situation of the network bandwidth by only using round-trip time in the prior art, the method can improve the reliability of the code rate adjustment according to the change of the
