Manufacturers LG and Samsung are working with the broadcasting industry's Open Mobile Video Coalition to develop a standard to launch the service in hundreds of markets. A rollout could come some time next year.
Anne Schelle, the executive director of the OMVC, said the two Chicago stations showed that the proposed standard is nearly ready for prime time: "Consumers can have access to live broadcast content anytime, anywhere."
"As we forge ahead with our shared objective of launching mobile DTV services in 2009, the standard has proven to meet the challenges of such complex terrain as Chicago," said Brandon Burgess, president of the OMVC and Ion Media Networks CEO. "We look forward to actualizing the mobile broadcast platform and providing consumers with real-time, full-motion television--traditional, broadcast and network TV content."
