ATSC Approves Mobile DTV

The ATSC TV standards company today said it has approved a candidate version of the Mobile DTV standard. The technology will give American cellphones, notebooks, portable media players and other devices a more universal way of watching over-the-air mobile digital TV provided by regular broadcasters rather than through proprietary, subscription-only services such as the MediaFLO network used by AT&T and Verizon.

The format will use H.264 encoding for video, rendering it compatible with many newer devices while also minimizing the amount of bandwidth used by broadcast towers. It will also have a data sideband that lets broadcasters send navigation data, news, sports or other one-way information through each TV channel.

ATSC hopes for commercial Mobile DTV service to roll out sometime in 2009 but hasn't mentioned any specific plans. Companies such as LG and Samsung have backed the standard early and are likely to be among the first to ship supporting products.

Mobile TV has had relatively sluggish adoption in the US in large part due to the added cost and carrier dependence of MediaFLO. Mobile TV is typically much more popular in countries like Japan and South Korea, where standards like 1Seg and T-DMB are often free to use and independent of any one provider.

    Oh, You Mean Like Japan?

    For several years now the Japanese have had the ability to watch over the air digital television on their cell phones without having to subscribe to one specific carrier or pay additional fees. My father-in-law's cell phone had this capability about three years ago. Nice to see the US of A finally play catch up.

    There's no reason that can be done in the US now. Its just the cell phone makers would have to add the capability.

    And even if they did, it would be useless, since the cell carriers would disable it first thing.
