Digital-TV Deadline Delayed

摘要

PRESIDENT BARACKObama signed a bill thatdelays the transition to all-digital television broadcastsuntil June 12, in an effort toprevent millions of residentsfrom losing their TV signals. However, 421 television stations across the country cut their ana-log signals on February 17, the original deadline; 220 other sta-tions had already shut off their analog feeds prior to the deadline. In late 2005, Congress passed legislation requiring U.S. TV sta-tions to move to all-digital broadcasts. Much of the cleared spec-trum, in the 700-MHz band, was sold in auctions. Experts say thespectrum is optimal for wireless broadband services.
