We may file this under the “future watch” category because this development could have a big impact on you in 2009.
Delivering video content to mobile devices in the digital age has been a challenging prospect for broadcasters and consumer electronics makers. LG Electronics and Harris Corporation yesterday announced at the Consumer Electronics Show the development of Mobile-Pedestrian-Handheld TV technology, or MPH, which will make it possible to receive digital TV signals while on the move with properly equipped mobile phones, portable media players, laptop PCs or automobile video systems.
According to Dr. Woo Paik, president and chief technology officer of LG Electronics, MPH will allow people to “watch digital TV anywhere, at any time, at broadcast quality, even (as they move) up to 140 miles per hour.”
This development could significantly impact the local broadcast content available to people with mobile devices, which broadcasters are hoping will help bring these consumers back from their other sources of information and entertainment, such as the Internet or mobile phone services that have been steadily siphoning off viewers during the last decade or so.
Successfully delivering a digital broadcast signal to moving devices is difficult, both on the broadcast end and on the receiving end. ATSC digital television — which was optimized for transmission to fixed receivers — will be the only high-power broadcast television service in the United States after February 2009, when high-power analog broadcasting ceases. Devices in motion often can’t maintain proper reception of the digital signal — especially at high speeds — and barriers such as skyscraper “canyons,” highway underpasses and natural geographical features often block the signal completely.

From the broadcasters’ perspective, as they have geared up for the switch to digital, their equipment is designed to process and deliver a full high definition signal. This is too much for a typical, small mobile device to handle.
According to Paik, the cost to add this capability to consumer devices is minimal. LG is showcasing several prototype products at CES, including two phones, a portable/mobile DTV screen, and a USB dongle, which will deliver the DTV signal to a laptop computer.
Also important is the relatively small impact this will have on broadcasters, as Harris’ solution only requires an addition to their full HD equipment, which is already in place.
Successful trials have already taken place in the Chicago area. In addition to free broadcast content, the system also allows for paid programming. Audience monitoring service Nielson has already developed a measurement system called Nielson Mobile for this new type of programming so that broadcasters can deliver the all-important audience numbers to advertisers.
LG hopes to have products available to consumer early next year. Expect also compatible in-car entertainment systems from Kenwood.
