EETimes has reported that the Advanced Television Systems Committee (ATSC), the US standards group responsible for digital TV, is developing a new standard for mobile TV called ATSC-M/H (ATSC-Mobile/Handheld). The standard will be targeted at the delivery of TV services to mobile and handheld devices, and is designed to be backward-compatible with the existing ATSC digital terrestrial TV standard. ATSC is currently used in the US to provide High-Definition TV broadcasts to TVs in the home.
The ATSC-M/H standard is actually the third standard being proposed for extending the existing ATSC broadcasts in the US market for mobile reception. The two other standards are A-VSB promoted by Samsung and Rohde & Schwarz, and MPH proposed by LG and Harris.
