TITLE: Fusion category and Hopf algebra
QUESTION [7 upvotes]: Let $H$ be a semisimple Hopf algebra over an algebraically closed field of characteristic zero. Further, let $K\subseteq H$ be a normal Hopf subalgebra. As we all know, $H$ then can be reconstructed from $K$ by some compatible data [1]. 
I want to know if there exists a similar result on Rep($H$) and Rep($K$), where Rep($H$) is the fusion category of finite-dimensional representations of $H$? If not, what can be said about Rep($H$) and Rep($K$)?
Thank you!

However, this article is written in the language of C*-tensor categories and compact quantum groups.
I hope this helps...
