Figure 3.166 FEC Packets-Non Block Alignment
An important question is determining the emission time of the FEC packets. If the
FEC packet is emitted just after the last packet used for the computation, a large
amount of packets will be output at the end of columns (in the last row) while a
smaller amount will be output at any other time. This causes an uneven bandwidth.
A more even bandwidth can be guaranteed by using a non-block alignment (see
Figure 3.166) or with delayed emission (see Figure 3.167).
