Abstract

In order to solve the technical problem of network resource waste or insufficiency of a constant code rate in the prior art, the invention provides a video encoding rate self-adaptive device and method in a mobile network environment. The device comprises an encoder, a buffer and a channel detector used for detecting the state of the buffer to determine whether a current network bandwidth is matched with a current code rate; a code rate controller of the encoder used for increasing or decreasing or maintaining the current code rate according to a detection result of the channel detector and making full use of the current channel capability on the premise of guaranteeing the implementation of upload or download; and thus the network utilization rate is expanded on the condition that effective data transmission can be guaranteed.
