Claim 8:
9. A device comprising:
at least one processor; and
a non-transitory computer readable storage medium storing a program for execution by the at least one processor, the program including instructions to cause the at least one processor to:
select an intra-prediction mode;
apply the 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, wherein the simplified transform is based on a discrete cosine transform (DCT) corresponding to multiplication of coefficients of DCT basis vectors by a constant;
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;
add the predicted block to the block of reconstructed residuals to generate a block of approximate reconstructed samples; and
store the block of approximate reconstructed samples in a memory.
