Body: <p>There are sentences:
  For analog video or MPEG (including DVD) output, the maximum range for R,G,B is [16, 235] (8-bit).
  For YUV, the maximum range for intensity (Y) is [16, 235] (8-bit).</p>
  
  <p>Is this saying correct ? I'm thinking that the <strong><em>first</em></strong> sentence contains an error. MPEG has YCbCr encoding ..
  What do you think about it ?</p>
