Harris Corporation, which invented the transmission standard for digital television, and LG Electronics have announced having developed an innovative new technology designed to extend over-the-air broadcast TV signals beyond the living room to viewers on the go.
LG Electronics and its US research subsidiary, Zenith Electronics, joined forces with Harris on the development of the new in-band mobile digital television (DTV) technology, which they have dubbed MPH for mobile-pedestrian-handheld.
The MPH system is a multiple-stream approach, with the main service stream for existing DTV and HDTV services, and the MPH stream for one or more mobile, pedestrian and/or handheld services.
Key attributes of the system include backward compatibility with the existing ATSC 8-VSB transmission and receiving equipment, the capability to receive broadcast signals at high (mobile) speed with a single antenna, and flexibility in both data rates and robustness.
The MPH system has the additional advantage for broadcasters of involving neither outside service providers nor spectrum-pooling arrangements.
The MPH in-band mobile DTV system will make its debut at the National Association of Broadcasters convention in Las Vegas. This promising technology, which has the potential to create new markets and revenue streams for TV broadcasters, will be prominently featured in two high-profile NAB exhibits. It will also be showcased in live, mobile demonstrations throughout the convention.
The results of our joint development with LG Electronics are in response to our customers’ interest in a compelling, in-band mobile solution, commented Tim Thorsteinson, president of Harris Broadcast Communications. The versatile, robust MPH system is the first that strikes the right balance for broadcasters looking to deliver both high-definition programming to fixed receivers and standard-definition programming and datacasting to mobile and handheld devices.
