In response to a request made to Ion by FCC Commissioner Jonathan Adelstein to organize a DTV transition testing campaign across the country, Ion Media Networks, along with NBC Universal, Telemundo and members of the Association of Public Television Stations, will spearhead analog shut-off (ASO) tests — planned as temporary interruptions of the over the air signals — in multiple major markets, including New York, Los Angeles, Washington and Hartford, Conn.

These tests are in preparation for the Feb. 17, 2009, government mandated analog shut-off and transition to digital television. Nearly all broadcasters, cable operators and satellite providers have joined in the effort.

The ASO tests, which are designed to ensure consumer DTV preparedness and a smooth transition to DTV, will begin in New York City, with a two-minute shutdown between 5:59 and 6:01 p.m. on Tuesday, Oct. 28. Participating New York metropolitan area stations include: WABC, WCBS, WFUT, WLIW, WNBC, WNET, WNJU, WNYE, WNYW, WPIX, WPXN, WWOR and WXTV.

Subsequent one minute tests will take place in Los Angeles and Washington on Tuesday, Dec. 2, and two 30-minute tests in Hartford on Wednesday, Dec. 3.

In addition, the broadcast partners will participate in existing tests being conducted across the country, like those in San Francisco, Philadelphia, and other areas with varied population densities and terrains.

"With a little over 100 days left to the national shutdown, it is critical that broadcasters unite, making a concerted effort to properly educate and prepare consumers well ahead of the deadline," said Brandon Burgess, chairman-CEO, Ion Media Networks. "By addressing viewers' concerns early through these tests and our ongoing education campaign, we are ensuring that no viewer will be left behind."

In September, Ion Media and its partners extended an invitation to broadcasters, cable companies, satellite providers, and relevant broadcast associations across the country to participate in the testing and to help generate elevated consumer awareness. Participation has been strong across all designated markets, according to Ion, with additional outreach continuing and a list of upcoming markets to be announced once confirmed.
