TV via cell phone

Beginning in April, eight television stations in Washington (DC) will broadcast a signal for a new class of devices that can show programming, even in a car at high speed.

The National Association of Broadcasters is showcasing the consumer benefits of some of the many innovations being delivered through digital over-the-air broadcasting at a gathering this week at the annual Consumer Electronics Show.

Watching live television broadcasts on mobile devices is common in some countries, but not the U.S. A new effort is taking shape to change that. A group of broadcasters plans to use this week's Consumer Electronics Show to promote their plans to deliver news, sports, weather and other local content to users on the go.

A proposal calling for reallocating broadcast television spectrum for wireless broadband use got a chilly reception from industry representatives.

The primacy of the TV platform is clear.

Dave Poltrack, CBS's chief researcher, has come up with an interesting theory: that most TV shows will be streamed through the Internet to be displayed on a variety of devices: TVs, computers, mobile devices.

It may not have been a practical alternative for viewers staring at blank television screens, but a mobile TV broadcaster was able to switch on nationwide in the US at the weekend as analog transmitters turned off.

The digital switch is the end of one TV era, but broadcasters and device companies hope it's opening up another. Their vision for the future: a world in which we access live television not just on big screens in our living rooms, but also on cellphones and computers and in cars.

Reeling from declining ad revenue and mounting debt from providing the expensive service at no additional cost to subscribers, South Korean cellular operators may soon cancel subway TV coverage that has yet to turn a profit.

Americans watched an all-time high of 151 hours of TV per month last quarter, according to a new Nielsen study. Our TV habits are on the rise across the "three screens"—TV, Internet, and mobile devices—but the most growth is coming from DVRs, Internet video, and mobile phones.
