The figure shows image samples and waveforms after the original video has been converted to HDV/DV format using the VC-300HD and then, again using the VC-300HD, converted to HD/SD-SDI output. In the conversion from HDV, once the MPEG2 decoding has been done, the scaler carries out processing to magnify or shrink the image.
