We have no doubt the justices of the Supreme Court are well versed and prepared for any copyright law, but do they understand TV or the hows and whys it can be so frustrating sometimes? Like many of us, possibly not that well -- like why HBO can't keep its streaming service up during Game of Thrones? -- which could make reaching a decision in the case between Aereo and the broadcasters seeking to put it out of business especially difficult. During today's oral arguments Justice Antonin Scalia wondered whether the cable- and satellite-only network HBO might be picked up by Aereo's antenna-to-internet setup. The justices were mostly on point, however, needling lawyers for the networks about a previous case for Cablevision's cloud DVR, and how a ruling in their favor could affect cloud internet services.
