Aereo, the television digital distributor, is arguing that an injunction entered in the United States District Court for the District of Columbia against its competitor, FilmOn X, does not affect its legal grounds to rebroadcast free TV programming over the Internet because it uses different technology. Hearst, which has a TV station in the Boston area, argues in the District of Massachusetts that the D.C. injunction against Aereo-competitor FilmOn X (once known as Aereokiller) shows that the use of individual antennas to rebroadcast its copyrighted television content does not defeat its public performance rights.
