Patent ID: 8005140

Claim:
A method of encoding a digitized video frame comprising: receiving the digitized video frame via a receiver; applying a motion compensation and a transform to the digitized video frame to obtain a transformed residual; applying a soft decision quantization to the transformed residual to obtain quantized transform coefficients; wherein applying the soft decision quantization includes computing a block of quantized transform coefficients, u, for each block in the plurality as u = arg ⁢ ⁢ min u ⁢  c - u ⊗ dq ⁡ [ p r ⁢ ⁢ em ] · 2 p quo / 64 ⊗ B  2 + λ · r ⁡ ( u ) ; and entropy encoding the quantized transform coefficients along with the motion compensation, wherein c is the transformed residual, dq[p rem ]·2 P quo /64{circle around (×)}B| is a dequantization calculation, λ is a Lagrangian multiplier, and r(u) is a number of bits for coding u.
