<div>Hello,</div>
<div> I am doing some basic Matlab simulations on DCT used in Video Compression. I have following questions arised out of that:</div>
<div> </div>
<div>1.) In a 16x16 MB , if one does a 8x8 size block DCT (4-times) for that MB in first case and a one shot 16x16 size block DCT in second case, Will the reconstructed block at the decoder will have same/similar values in both cases?</div>
<div> </div>
<div>2.) Which case would there be any benefit in terms of lesser residue, lesser bits needed for coding etc?</div>
<div> </div>
<div>3.) Will this analysis of block DCT also hold true for other transform like the integer transform used in H.264 codec?</div>
<div> </div>
<div>Regards</div>
