Claim 0:
1. An encoder, comprising:
a coding control component, configured to:
receive a digital video frame; and
divide the digital video frame onto a plurality of coding units (CUs);

a transform component coupled to the coding control component, the transform component configured to perform block transforms on the plurality of CUs, to generate a plurality of transform coefficients; and
a quantize component coupled to the transform component, the quantize component configured to:
determine a plurality of parameters of a structural similarity index (SSIM)-based distortion model for the plurality of CUs, based on previous CUs; and
quantize the plurality of transform coefficients based on the plurality of parameters, to generate a plurality of quantized coefficients.
