Even as it waits for the Supreme Court to weigh in on its fate sometime this month, online video start-up Aereo is forging ahead with its plans. This week the Barry Diller-backed streamer will launch a player app for Google’s (News - Alert) Chromecast dongle.

It was supposed to be launched last week, but Aereo said it was working out bugs in the app.

"We are delaying release of Chromecast support to June 4 to work out a few kinks. Bummed about the delay, but next week is gonna rock!" the company said by tweet.

Aereo subscribers in 12 cities will have access to Chromecast, including major cities like Atlanta, Boston, Dallas, Houston and New York. Aereo also supports iOS devices, Google Android in beta form, as well as Roku and Apple (News - Alert) TV players.

Meawhile, the company awaits the high court’s ruling on its fate. Aereo went to the Supreme Court in April to defend its right to exist in the face of copyright infringement suits from every major broadcaster—the argue that because the company broadcasts local feeds via the Internet without paying retransmission fees, it’s essentially stealing their content. Aereo has counter-argued that because it provides dime-sized antennae to its subscribers — who pay $8 per month for access to a couple dozen channels — it constitutes an over-the-air, rabbit ears-based service, which is exempt from retrans fees. It has also argues that its content is delivered to a single cloud-based DVR device for one subscriber and can therefore not be categorized as a public broadcast service, subject to fees and regulations.

So far, it has mostly succeeded in its arguments, winning legal challenges in a handful of cases. In Boston, Federal Judge Nathaniel M Gorton has issued a ruling in the United States District Court for the District of Massachusetts in a suit brought by Hearst Stations on behalf of its local TV station, WCVB-TV. The judge denied the plaintiff its motion for a preliminary injunction against Aereo. It also won in New York.

It has however been ordered to shut down in the west, including Denver and Salt Lake City, following a ruling by the 10th Circuit Court of Appeals in Denver affirming a preliminary injunction by US Circuit Judge Dale Kimball, who ruled that Aereo does indeed violate U.S. copyright law.

For now, the company is waiting and watching to see what happens. "Consumers have a fundamental right to watch over-the-air broadcast television via a modern antenna and to record copies for their personal use," CEO Chet Kanojia said. "The Copyright Act provides no justification to curtail that right simply because the consumer is using modern, remotely located equipment."
