LG Electronics Inc. and Harris Corporation , joint developers of the Mobile-Pedestrian Handheld in-band mobile digital television system, submitted a proposal to the Advanced Television Systems Committee (ATSC) for a standard that would enable broadcasters to provide high-quality digital television (DTV) signals to a wide range of mobile and portable devices. The ATSC is an international, non-profit organization developing voluntary standards for digital television systems.

The ATSC Technology and Standards Group requested proposals from companies offering systems aimed at facilitating the delivery of DTV programming and data to mobile, pedestrian and handheld devices via the digital broadcast signal. LG and Harris submitted a proposal detailing their technology for the delivery of mobile and handheld DTV, which is backward-compatible to the current standard.

The broadcast and consumer electronics industries have identified mobile and handheld DTV as important new opportunities for the future of local broadcasting - providing new revenue streams for device manufacturers and broadcasters, and new services to customers. These new mobile and handheld services, using ATSC-compatible broadcast transmissions, can help spur the adoption of handheld devices by consumers who want value-added services that are currently not available through regular broadcast TV delivery models. With MPH, consumers can view their favorite programs from local broadcasters, watch movies and sports, check local news and weather information and access pay services - even when traveling in fast-moving vehicles or using handheld video devices away from home.

Developed by Harris Corporation and LG Electronics Inc. and its U.S. research subsidiary, Zenith, the MPH in-band mobile DTV system provides robust DTV signals to mobile, pedestrian and handheld devices. Harris, a known leader of television transmission systems, and LG Electronics, a leading developer of receiver systems and DTV standards, designed MPH to be fully compatible with the ATSC A/110 standard for distributed transmission. As such, the system provides a highly compatible, commercially deployable system that has already been accomplished, tested and demonstrated.

Until now, reliable reception of signals transmitted by terrestrial broadcasters has not been possible in fast-moving vehicles or pedestrian handheld devices such as mobile phones or laptop computers. Unlike the cellular-based approach, MPH(TM) technology uses only the single, existing transmitter from commercial and public broadcasters. For broadcasters, this new technology enables new and potentially lucrative revenue streams.
