Abstract

Systems and methods for multi-layered rate control for scalable video coding. A parameter value may be calculated based on a current layer target bit rate and a current layer buffer state for a frame in a video stream. The frame may include a lower layer and one or more higher layers. A determination may then be made as to whether the current layer is the lower layer. If the current layer is the lower layer, a determination may then be made as to whether a coupling request has been received from a higher layer in the frame. If the coupling request has been received from the higher layer in the frame, the parameter value for the current layer may be increased based on a buffer state threshold value of the higher layer in the frame.
