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. In the 1080i output, you can see that the HDV characteristics are output more or less unaltered.
