Many electronics manufacturers find themselves waiting to reach an agreement with broadcasters on a technology standard for a new generation of energy-efficient mobile televisions that could work in cell phones, iPod-like portable players and PDAs. Broadcasters would then transmit a separate signal to these devices. 

In an era of dazzling battery-powered portable devices including iPods, computers and cellphones, it’s hard to imagine what it’s like to be unable to catch the news and entertainment anytime and anywhere we want.
