HDMI AV receivers — Sony

I’m going to convert sometime in the next 6 months to an HDMI receiver I think — here are some Sony units — CrunchGear » Archive » Sony is adding three ES receivers to its 2008 line-up — I am wondering if I have to convert my current TV as well — it doesn’t have HDMI input, only component — will these receivers convert HDMI in to RGB? Need to learn more about the technical and DRM aspects of this.
