Kudos for making things accessible. However, joint source-channel coding is not news, especially at the level of scalable video coding (probably 20-year-old research by this point). In academia this isn't as exciting as it sounds to industry.
In a completely different way (i.e. DASH). SVC came out with bad timing, as the move towards HTTP video was gaining momentum. Also, around 2008(?) or so when the spec was finalized, there was no HW encoding support, so it was pretty unusable in practice.
The idea of using layers, though, is much older (I remember reading papers about this already back in 2001 or so)
