A bandwidth control method, a bandwidth control device, and a bandwidth control system are provided. In the method, complexity information about the current video sequence of a video signal in each channel is acquired. Then, the complexity information about the current video sequence of the video signal in each channel is quantified, and a current-video-sequence complexity level of the video signal in each channel is obtained according to the complexity information. Finally, a total bandwidth is distributed to the video signal in each channel according to the current-video-sequence complexity level of the video signal in each channel. Therefore, a bandwidth is dynamically distributed to the video signal in each channel. In this way, the total bandwidth can be reasonably utilized, and an occurrence probability of video quality deterioration can be lowered.
