user12268: 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).
Is this saying correct ? I'm thinking that the first sentence contains an error. MPEG has YCbCr encoding ..
What do you think about it ?

user1871: Yes, MPEG-2 video is stored as YCbCr, but video editing programs (like Cinelerra) convert the samples to RGB for processing during editing. That range is 16-235.
From Wikipedia on YCbCr

Analog YPbPr from analog R'G'B' is derived as follows:


To get a YUV output in the 16-235 range, the input RGB is also limited.
