<!-- Maintain a fragment named "3channel" to preserve incoming links to it -->
<dfn id="3channel">channel</dfn>. Each channel has a sample depth in the range 1 to 16, which is the number of bits used by every sample in the
channel. Different channels may have different sample depths. The red, green, and blue samples determine the intensities of
the red, green, and blue components of the pixel's color; if they are all zero, the pixel is black, and if they all have
the red, green, and blue components of the pixel's color.

<p>The following table describes the quantization of image black to image peak white (signal range). By default the signal range is full-range
but it can also be represented as narrrow range, which conforms to quantization in broadcast video which typically uses the YCbCr Color
Representation. cICP can specify this specific range:</p>

I think this line can be removed. It accidentally adds an extra table inside the other table. Notice, it also never gets closed.

all pixels are fully opaque. (It is also possible for a four-channel reference image to have all pixels fully opaque; the
difference is that the latter has a specific alpha sample depth, whereas the former does not.) Each horizontal row of
