The ATSC Technology and Standards Group, with due regard for existing standards organizations and activities, develops and recommends voluntary, international technical standards for the distribution of television programs to the public using advanced television technology. Technologies considered may be improvements to current systems or entirely new systems that are compatible or incompatible with current systems. All forms of distribution systems may be considered, such as terrestrial broadcasting, cable systems, direct satellite broadcasting, and pre-recorded media. With respect to distribution systems, sound, vision, display, conditional access, and data sub-systems may be considered.

The Specialist Group on ATSC Mobile/Handheld (M/H), TSG/S4, under the supervision and direction of the Technology and Standards Group, will evaluate "backwards compatible" proposal(s) for delivery to mobile and handheld devices using the DTV broadcast signals, will develop recommended changes to existing Standards, will develop new Standards when necessary, and where applicable develop associated Recommended Practices for mobile and handheld services using DTV broadcast signals. These documents will provide for delivery of real-time and non-real-time television content and data to mobile and handheld devices (including those defined as "pedestrian"). These ATSC-M/H services shall have the capability to be carried in existing ATSC DTV broadcast channels. The presence of these new M/H services shall not preclude or prevent operation of current ATSC services in the same RF channel or have significant adverse impact on legacy receiving equipment. Wherever possible, these standards will build on existing standards of the ATSC or other standards development organizations. This activity will include liaison with other Specialist and Planning Groups inside the ATSC as well as other standards development organizations and technology committees working on standards that include mobile and handheld technologies.

TG1/S9: RF Transmission. Chair: Charles Einolf, Consultant
Charlie worked for Westinghouse for over twenty-seven years, including two years at the Westinghouse Wireless Solutions Company (now iBiquity Digital), and was responsible for the design and development of the advanced electronic systems incorporating sensor, computer, communication and signal processing techniques. In 1996, Charlie took advantage of the opportunity to become involved in digital television, and joined the Advanced Television Technology Center (ATTC) as Deputy Executive Director. He was responsible for its technical programs until the completion, in 2003, of its mission to facilitate the transition to digital television in the United States. During his tenure at ATTC, Charlie became actively involved in the technical aspects of the digital television broadcast industry, including RF, propagation, and reception analysis.
Currently, Charlie participates in a variety of ATSC specialist and ad hoc groups, including serving as chair of the ATSC T3/S9 Specialist Group on RF Transmission. He also participates in the standards activities of the International Telecommunications Union Radiocommunications (ITU-R), and is chair of the United States ITU-R Working Party 6P on Content Production and Postproduction.
Dr. Einolf holds a Ph.D. and M.S. degree in Electrical Engineering from the University of Rochester, and a B.S. degree in Electrical Engineering from the Massachusetts Institute of Technology. He is a Fellow of the Institute of Electrical and Electronics Engineers. He is currently the vice-president of the IEEE Broadcast Technology Society and chairs its Publication Committee.

Wherever possible, these standards will build on existing standards of the ATSC or other organizations. This activity will include liaison with other ATSC Specialists Groups.
TG1/S10: Receivers. Chair: John Henderson, CEA
Henderson chairs the Technology and Standards Group, as well as the T3/S10 Specialist group on Receivers and the T3/S11 specialist group on Compliance and he is thankful that the groups have not yet had simultaneous active periods. Currently, T3/S10 is writing a voluntary Recommended Practice that contains receiver front-end performance guidelines. Clearly searching for the right word to describe the group’s sometimes highly charged deliberations, Henderson settled on "exciting."
At the 2005 Annual Meeting on May 10, 2005, John received the "Bernard J. Lechner Award for Outstanding Contributions." In particular, ATSC recognized John’s leadership of S10 in the development of ATSC Recommended Practice A/74 "Receiver Performance Guidelines.” John’s ability to bring the various industry segments together not only resulted in the publication of this important document, but also helped foster a better understanding of the complex technical issues.
Henderson’s immersion in consumer electronics product development and technology application began immediately upon graduation from college, when he joined RCA Laboratories. He continued with RCA Labs and its successor, Sarnoff, until 1991, when he joined Hitachi America R&D. As an individual contributor, team member, or manager with RCA and Sarnoff, he has contributed to television tuner control systems, IF filter design, video, and to systems brought by Sarnoff to the ACATS process. At Hitachi, he has managed digital TV, cable modem, and wireless modem product design. He holds more than 25 issued US patents and has presented numerous papers in these areas. He is a Fellow of the IEEE. Henderson received a BSEE cum laude from the University of Pennsylvania and an MSE from Princeton University.
Henderson treasures the recreational time that he manages to set aside. He is a fairly active bicycle rider, peddling about 5000 miles per year, with usually half of this distance being on a tandem with his wife. He is an amateur classical and church organist, having taken organ lessons at Westminster Choir College in Princeton "until work demands overwhelmed the required practice time." He likes to sail, and, although he no longer does much racing, he and his wife day-sail a traditionally gaff-rigged 19-foot catboat. He enjoys woodworking and building small boats ("limited by what I can get out of the basement").
TSG/S10 will examine elements of DTV receiver designs, assessing the degree to which performance tradeoffs and complexity are impacted and their relation to FCC DTV planning factors. TSG/S10 may also consider whether voluntary performance targets and/or design guidelines might be useful.
