Yet another driving distraction?

LG Electronics and Samsung have been separately working on technology standards for mobile digital TV that can be delivered on the road. The only problem is that the two standards are incompatible: one uses AVS-B, while the other uses MPH.

In what could have unfolded as another battle of HD DVD vs. Blu-Ray, both companies have instead entered into an agreement to work together to develop a common mobile digital TV standard for the U.S.

Getting a digital signal on a moving TV can pose major reception problems, as TV signals bounce off other cars, buildings and other structures and are reflected; this confuses the signal decoder and scrunches the signal as you approach an antenna and then spreads the signal out as you drive away from it. 

LG and Samsung claim that their technologies have fixed these problems with heavy-duty error correction to help the tuner verify that it received the right information.

The new mobile digital TV standard will reportedly originate from local TV stations in a version of the digital ATSC standard that can be transmitted alongside their HD broadcasts and use the same antenna.

The companies must next sort out and agree on the technology with the Advanced Television Standards Committee (ATSC). They estimate this new technology will be available to TV stations and in receivers sometime in 2009.
