The matrix FEC policy combines row- and column FEC.
This gives the advantage of being able to recover more than one lost packet per row AND recover more than one lost packet per column.
In addition, the added latency compared to column FEC is negligible(可以忽略的).
When using the 2D parity matrix scheme with a specific set of parameters the term XOR(L, D) is usually used to describe this in written text.
