Default Qn about spdif blocks and frames

I understand that data is sent in blocks over an spdif connection and each block has 192 frames which again have two subframe of 32 bits each, and the structure of the subframe is something like mentioned in this article - http://en.wikipedia.org/wiki/AES/EBU#The_Protocol

However, what I'd like to know is how does the receiver know where the subframe begins ?

Is it really the preamble ? Does it determine the start of the frame based on those first three (or four?) bytes of data ?
