Technology Group 3

The ATSC Technology Group 3 (TG3), with due regard for existing standards organizations and activities, develops and maintains voluntary, international technical Standards, Recommended Practices and other documents for the distribution of television programs and other data using advanced terrestrial broadcast technology, internet and other transports. Technologies considered may be improvements to current systems or entirely new systems that are compatible or incompatible with current systems. As appropriate, TG3 may engage in activities to address implementation issues regarding ATSC Standards and other documents.

Chair: Luke Fay, Sony

Fay, senior manager of technical standards at Sony Home Entertainment & Sound Products – America, has been Vice Chair of the “TG3” Technology Group since its inception in 2011. He has chaired the ATSC Specialist Group on Physical Layer (S32) since 2012 and has served as Vice Chair of ATSC Specialist Group on interactivity (S38). In recognition of his leadership, he received the ATSC’s highest technical honor, the Bernard J. Lechner Outstanding Contributor Award, in 2015.

At Sony, Fay is heavily involved in the development of the next generation of broadcast television in a number of standards organizations and their efforts to educate members of the new possibilities available with ATSC 3.0. He has more than 20 years of experience in digital communications systems engineering and receiver design, starting with cable modem demodulators in 1996, followed by work on ATSC 1.0 demodulators, developing early receiver chips for digital television.

He earned his bachelor’s degree in Electrical Engineering from the University of Arizona and master’s degree in Electrical Engineering from National Technological University. He has been granted 13 patents with 10 more pending in the area of Digital Signal Processing.

TG3 Specialist Groups


  • TG3/S31: System Requirements and Program Management

    Chair: Oren Williams, Dolby laboratories

    Scope

    The Specialist Group on ATSC 3.0 System Requirements and Program Management (called TG3/S31) will solicit use cases and develop scenarios, and examine them within various industry contexts for the next-generation digital television broadcast system (ATSC 3.0). These scenarios will be used to derive a set of System Requirements and the associated Glossary for ATSC 3.0, which will in turn enable the development of Technical Standards and Recommended Practices for such future service by TG3 and its other subgroups. The group will manage the ongoing development and documentation of these System Requirements and Glossary as appropriate over time.

    The group will assist in the review, coordination and consolidation of work within TG3’s subgroups, including reviewing subgroup output for adherence to the System Requirements, coordinating interdependent deliverables and timelines, assisting in identifying and resolving work overlaps or gaps between groups, drafting outlines and shared sections of documents requiring multiple subgroup input, and other similar tasks as assigned by TG3.

  • TG3/S32: Specialist Group on Physical Layer for ATSC 3.0

    Chair: Dr. Jae-young Lee, ETRI
    Vice-Chair: Dr. Mark Earnshaw, Coherent Logix

    Scope

    The Specialist Group on Physical Layer for ATSC 3.0 (called TG3/S32) will examine, assess, and possibly recommend technical proposal(s) for the physical layer(s) of the next generation digital terrestrial television broadcast system (ATSC 3.0). Interoperability with non-broadcast distribution systems (both traditional and non-traditional) will be considered. The term “television” should not in any way constrain the Specialist Group from considering physical layer technologies, systems and services that may currently fall outside the traditionally defined boundaries of television broadcasting.

  • TG3/S33: Specialist Group on Management and Protocols

    Chair: Dr. Youngkwon Lim, Samsung Electronics America, Inc.
    Vice-Chair: Adam Goldberg, Sony

    Scope

    The Specialist Group on Management and Protocols (called TG3/S33) will solicit, examine and assess technical proposals and develop Standards and Recommended Practices related to technologies for the management and delivery of ATSC 3.0 services and associated metadata, over terrestrial broadcast channels and, if appropriate, broadband/bi-directional networks, to fulfill the relevant ATSC 3.0 System Requirements.

  • TG3/S34: Specialist Group on Applications and Presentation for ATSC 3.0

    Chair: Chris Homer, PBS

    Scope

    The Specialist Group on Application and Presentation for ATSC 3.0 (called TG3/S34) will examine and assess technical proposals and develop Standards and Recommended Practices for the next generation digital terrestrial television broadcast system to fulfill the relevant ATSC 3.0 System Requirements. The Specialist Group will primarily focus on the portion of the ATSC 3.0 platform that defines the user experience. The work may include, but is not limited to accessibility (including video description and closed captions) and other features as defined by evolving system requirements across a multiple delivery path, multi-device ecosystem.

  • TG3/S36: Specialist Group on ATSC 3.0 Security

    Chair: Adam Goldberg, Sony
    Vice-Chair: Chris Homer, PBS

    Scope

    The Specialist Group on the ATSC 3.0 Security (called TG3/S36) will develop standards and other documents that describe the security and conditional access infrastructure of the ATSC 3.0 system, including mechanisms for supporting conditional access features like pay-per-view and subscription services. This also includes mechanisms for cryptographically protecting communications within the ATSC 3.0 system and cryptographic verification of downloaded applications.

  • TG3/S37: Specialist Group on Conversion and Redistribution of ATSC 3.0 Service

    Chair: Steve Calzone, DTV Consulting
    Vice-Chair: Jeff Hamilton, Hamilton Technologies

    Scope

    ATSC TG3/S37 develops and maintains Recommended Practices, Standards, and other documents relating to the conversion and redistribution of ATSC 3.0 services.

  • TG3/S38: Specialist Group on Interactive Environment

    Chair: Mark Corl, Triveni Digital
    Vice-Chair: Julia Kenyon, Duct Tape Engineering

    Scope

    The Specialist Group on Interactive Environment for ATSC 3.0 (called TG3/S38) examines and assesses technical proposals regarding interactive applications and their companion devices. This analysis is done in order to develop Standards and Recommended Practices that describe a supporting environment delivered via the next generation digital terrestrial television broadcast system. S38 may undertake other related tasks as defined by system requirements or as assigned by TG3.
