Claim 4:
5. The method of claim 1, wherein the applying the inverse color space conversion comprises:
in response to the ACT flag indicating that the ACT is enabled, the color space conversion equations is applied based on the color space equations including

tmp=rY[x][y]—(rCb[x][y]>>1),

rY[x][y]=tmp+rCb[x][y], 

rCb[x][y]=tmp−(rCr[x][y]>>1), and

rCr[x][y]=rCb[x][y]+rCr[x][y],, regardless of a value of a flag indicating whether transform and quantization are bypassed for the residual blocks of the current CU.
