  We study spatiotemporal intermittency in a system of coupled sine circle
maps. The phase diagram of the system shows parameter regimes where the STI
lies in the directed percolation class, as well as regimes which show pure
spatial intermittency (where the temporal behaviour is regular) which do not
belong to the DP class. Thus, both DP and non-DP behaviour can be seen in the
same system. The signature of DP and non-DP behaviour can be seen in the
dynamic characterisers, viz. the spectrum of eigenvalues of the linear
stability matrix of the evolution equation, as well as in the multifractal
spectrum of the eigenvalue distribution. The eigenvalue spectrum of the system
in the DP regimes is continuous, whereas it shows evidence of level repulsion
in the form of gaps in the spectrum in the non-DP regime. The multifractal
spectrum of the eigenvalue distribution also shows the signature of DP and
non-DP behaviour. These results have implications for the manner in which
correlations build up in extended systems.
