WASHINGTON, Oct. 24, 2007 — MPH in-band mobile digital television (DTV) represents superior technology and marketplace opportunities, according to technical details submitted last week to the Advanced Television Systems Committee (ATSC) standards-setting process by co-inventors LG Electronics and Harris Corporation (NYSE: HRS).
Presented in the format for ATSC Candidate Standard, the MPH in-band mobile DTV documentation explains the detailed architecture of the modulation system's capabilities to provide robust, over-the-air DTV signals to mobile, pedestrian and handheld devices. For consumers, MPH enables users to view their favorite programs from local broadcasters, watch movies and sports, and access local news and weather information, even when traveling in fast-moving vehicles or using handheld video devices away from home. For broadcasters, this new technology has the potential to create lucrative new revenue streams.
MPH engineers and executives from Harris Broadcast Communications, LG Electronics and LG's U.S. R&D subsidiary, Zenith, have been actively participating in the accelerated ATSC standard-making process since early summer. The 80-plus page document on the MPH transmission/modulation technologies not only discloses all the technical details of the MPH system's robust and multi-program capabilities, but also includes extensive descriptive information to enable reviewers to understand, evaluate and appreciate its many unique features. The document will become the basis for an ATSC Candidate Standard that meets and exceeds the ATSC's mobile-handheld DTV goals by simply deleting the descriptive information.
An additional portion of the submission describes two candidate systems for efficient delivery of compressed audio for monaural, stereo and surround-sound to handheld and rear-seat MPH consumer products. Two well-known and already-standardized approaches have been recommended: Neural-Extended Adaptive-Multi-Rate Wideband (AMR-WB+) and High-Efficiency Advanced Audio Coding (HE-AAC-v2) will each meet the low bit-rate and high quality requirements associated with the MPH enhanced streams. The MPH team will work with the ATSC to ultimately decide upon a single, all-around optimum solution.
The MPH system utilizes the widely accepted H.264 MPEG4 (moving picture experts group) video compression standard as the video codec. Choice of this codec is consistent with other standardized implementations of mobile television worldwide.
In addition, the MPH team has also submitted documents in support of a subsequent choice for the Management Layer by technically detailing both an approach using the current ATSC MPEG Transport Stream and an approach utilizing IP (Internet Protocol). The MPH team will work with the ATSC to decide the single, optimum approach to the Management Layer protocol.
The MPH mobile DTV system leverages Harris Corporation's expertise in broadcast systems — including transmitters, exciters, encoders and management software — and the systems development, integrated circuit design and vast consumer electronics experience of LG Electronics and its U.S. subsidiary, Zenith.
This in-band mobile DTV technology, under development for more than two years at the LG Electronics DTV Laboratory in Seoul, South Korea, and at LG's Zenith lab near Chicago, builds on two key ATSC standards, also developed by Zenith: the robust Enhanced VSB (E-VSB) system and 8-VSB (Vestigial Side Band), the proven modulation system at the heart of the ATSC DTV standard currently used by more than 1,500 U.S. DTV broadcasters and in every DTV receiver sold in the United States.
To help commercialize its technology concepts for the broadcast industry, LG Electronics turned to long-time industry leader Harris Corporation. Harris Corporation's extensive systems integration and research capabilities contributed significantly to the broadcast system's development.
The overarching goal of the companies was to devise a robust, ATSC-compatible mobile solution for local broadcasters to maximize the use of their 6-MHz, 19.39 megabit-per-second digital pathway in providing a wide range of compelling and profitable consumer services. This meant maintaining the centerpiece application, digital HDTV, to the tens of millions of fixed receivers in U.S. homes, while simultaneously reaching viewers on-the-go with a low-bit-rate digital TV signal and data services.
