The Supreme Court only ruled under the current copyright laws. Congress is free to change the copyright laws as it sees fit to explicitly allow services such as Aereo or clarify what cloud based services can do and not, but considering the big media companies who either own the content and/or the big broadcast networks also own most of our lawmakers, we won't see much change in the current copyright laws for a long and, perhaps, only strengthening the media owners current position. For this ruling under current copyright laws, the Supreme Court viewed Aereo's methods of providing the local channels as no different than cable or sat, while the lower courts (plural) did view them as different than cable or sat.
