It means that the input and output rates have a fixed relationship between them. E.g., 1:1, 1:N, N:1 On the other hand, if you subclass gr_block, you can construct blocks that have an arbitrary relationship between the rate of consumption on each input and the rate of production on the outputs. Using gr_block entails a bit of extra work for the programmer, hence gr_sync_block, gr_sync_decimator, and gr_sync_interpolator are used when you've got a fixed rate between input and output.
