Claim 16:
17. A non-transitory computer readable medium comprising instructions which, when executed, cause processor circuitry to at least:
apply a intra-prediction mode to an original block of video data to generate a predicted block;
subtract the predicted block from the original block to generate a residual block;
apply a simplified transform to the residual block to generate transform coefficients by multiplying coefficients of vectors by a constant to generate products and applying a floor function to the products;
apply a simplified quantization to the transform coefficients to generate quantized transform coefficients;
apply an inverse quantization to the quantized transform coefficients to generate dequantized coefficients;
apply an inverse simplified transform to the dequantized coefficients to generate a block of reconstructed residuals; and
add the predicted block to the block of reconstructed residuals to generate a block of approximate reconstructed samples.
