Affiliates of CBS and Fox Broadcasting on Monday filed a new lawsuit in federal court in Utah against streaming TV service Aereo.

Community Television of Utah alleges in its complaint that the Barry Diller-backed startup infringes copyright by enabling paying subscribers to TV shows directly to iPhones and other devices. The broadcaster -- which operates KSTU (Fox), KUTV (CBS) and KMYU (My Network TV) and -- is asking a federal judge in Utah to issue an injunction prohibiting Aereo from operating.

Aereo already faces virtually identical lawsuits in New York and Boston. So far, the startup has defeated broadcasters' attempts to shutter the service in New York, where a federal appeals court ruled recently that Aereo does not appear to infringe copyright. A federal judge in Boston likewise said recently that he is inclined to reject the broadcasters' request to order the service to cease operating.
