摘要：
A fast method to reduce the computational complexity of a frequency domain transcoder for bit-rate reduction of compressed video bit streams is proposed. The proposed method reduces the computational complexity of a pixel domain transcoder by 81.25% while the introduced distortion in the transcoded pictures is <0.2dB.
