The ATSC-compatible “MPH” in-band mobile DTV system, developed by LG Electronics, Harris Corp. and Zenith, was demonstrated outside of North America for the first time at the CAPER 2007 International Broadcast Conference in Argentina. Of interest to U.S. broadcasters who will be returning to their VHF channels after the DTV transition, the demonstration was transmitted on 6 MHz-wide Channel 12, with an ERP of 25 kW. ARTEAR (Arte RadioTeleviso Argentino) provided the digital transmission facilities.

During the demonstration, Channel 12 transmitted two MPH streams and one ATSC HDTV program. One of the two mobile streams was a simulcast of the normal Channel 12 program. Prototype MPH receivers developed by LG Electronics were used to receive and display the MPH mobile programs.

“Demonstrating the robust capabilities of ATSC-compatible mobile DTV in South America underscores the flexibility of ATSC DTV for broadcasters and policy-makers,” said Robert Graves, chairman of the ATSC Forum.

Graves added that the MPH system’s ability to simultaneously deliver HD and multiple programming SD streams within the same 6 MHz ATCS channel would provide “exciting new programming options” for handheld and mobile receivers.
