Abstract
An encoder includes a frame level processing circuit, a coding tree unit (CTU) level processing circuit and an encoding circuit. The frame level processing circuit is arranged to calculate a bit number of a current frame according a target bitrate and a frame rate, and the frame level processing circuit is further arranged to calculate a quantization parameter of the current frame according to the bit number of the current frame and at least one parameter. The CTU level processing circuit is arranged to use an adaptive quantization mode to adjust the quantization parameter to generate an adjusted quantization parameter. The encoding circuit is arranged to encode the current frame to generate output data according to the adjusted quantization parameter.
