Parameters
In the common case, each element of the matrix contains the name of a color plane
from which a sample should be taken. The exception is for vertically sub sampled
color planes. These are indicated by writing the names of two color planes in a single
element, one above the other. Samples from the upper color plane are transmitted on
even rows and samples from the lower plane transmitted on odd rows as shown in

them.
The Avalon-ST Video protocol does not force the use of specific color patterns,
however a few MegaCore functions of the Video and Image Processing Suite only
process video data packets correctly if they use a certain set of color patterns.

R
Three color planes, B’, G’, and R’ are transmitted in alternating sequence and each
B’, G’, or R’ sample is represented using 8 bits of data.
Three color planes are transmitted in parallel, leading to higher throughput than
when transmitted in sequence, usually at higher cost. Each R’, G’, or B’ sample is
represented using 10 bits of data, so that, in total, 30 bits of data are transmitted
in parallel.

as Cb or Cr samples. One Y’ sample and one of either a Cb or a Cr sample is
transmitted in parallel. Each sample is represented using 10 bits of data.
