uh, some help please ?

I have to understand the difference between DPSK and PSK
I know PSK just changes the phase by 180 degree's each time the following bit of data is different from the previous.
I understand DPSK is used to overcome the problem of delays in data transfer which can occur randomly making PSK in-efficient.

So what is DPSK in relation to PSK?
