It's not that hard. You don´t need to crypt all the datastream. Time
ago, when I was at university (I'm 26) there was a project for a pay per
view decoder and the encryption only was done over a block every "n"
blocks. Since the image is compressed, any change in the stream has
drammatic effects.

I have a paper at home? with examples.
