Image reconstruction after applying dwt

I have applied dwt2 on 2D image, applied source and channel coding on LL sub band and transmitted it.
Now I have a question on the receiver side. Do I have to apply source and channel coding on HL, LH, HH and transmit as well to reconstruct the image on the other end (using idwt)? Is it possible to reconstruct LL sub band without the rest? I am asking this so as to save the computational time. What do you guys suggest?
