April 12, 2024- Adam Goldberg of Sony Electronics Named Chair of A3SA Technical Contributors Working Group

A3SA, the ATSC 3.0 Security Authority, today announced that Adam Goldberg of Sony Electronics has been elected Chair of the organization’s Technical Contributors Working Group.

“A3SA is delighted to confirm the election of Sony’s Adam Goldberg as chair our Technical Contributors Working Group, which was established to get broad industry feedback on content security operations and processes from a wide assortment of broadcasters, consumer technology companies, security vendors, broadcast equipment manufacturers, and other technical solution providers. Based on his longstanding work with both the consumer technology and content businesses, we know Adam is a good choice to balance the needs of both in his role as TCWG chair,” explained Ron Wheeler, A3SA Managing Director. “Adam has a long history working on security matters, having chaired every ATSC security committee since the 1990’s. He is well respected as an authority who is also known for his fairness when competing interests need to discuss options with new implementations.”

The A3SA Technical Contributors Working Group is a primary way for A3SA’s partners to provide input on the A3SA security ecosystem, including feedback on specifications and verification requirements, as well as other topics.

Goldberg is Director, Technical Standards at Sony Electronics. For more than 30 years, he has been involved in the standardization of digital television technologies. He has been deeply involved in development of various components of digital television, including receivers, receiver silicon, and broadcast equipment. His current focus is security and energy efficiency and ATSC 3.0, and he is the co-chair of three technical committees of the Consumer Technology Association (CTA R14WG1, chair of CTA R4, co-chair of CTA R4WG13) as well as chair of the ATSC 3.0 Specialist Group on ATSC 3.0 Security (S36).

“The TCWG of A3SA performs a valuable role as the primary forum for receiver implementors and broadcasters to discuss enhancements, changes, and issues with the A3SA specifications. I look forward to bringing together the various players who work to ensure that consumer expectations are met in a secure environment,” Goldberg said.

About A3SA:  The ATSC 3.0 Security Authority (A3SA) develops protocols for securing ATSC 3.0 broadcast services by leveraging the same type of tools now commonplace with web-based delivery – including IP-based encryption protocols, device certificates and rights management technology.  A3SA’s protocols are in conformance with the ATSC 3.0 Security Standard for next-generation broadcasting.  A3SA provides device manufacturers and broadcasters with access to standardized protection and security credentials that enable secure delivery of high-value television content while preserving adding new features to free over-the-air television across the USA.

March 7, 2024- A3SA Policy: Individual Viewer Data Not Tracked by Content Protection Technology

ATSC 3.0 Security Authority LLC (“A3SA”) operates, via a contractor, a proxy server to process requests from ATSC 3.0 receivers (such as televisions or set-top boxes) for cryptographic credentials to decrypt ATSC 3.0 television broadcast signals encrypted by Google’s Widevine technology pursuant to the A3SA content protection specifications.

Because such receivers use the Internet to make requests for decryption credentials, the proxy server is necessarily provided with the Internet protocol (“IP”) address of each receiver based on the Internet service used at its location (e.g., a household).  As part of the decryption credentials request, the receiver also provides a unique device identifier to the proxy server.  A3SA does not collect or authorize the collection on its behalf of any other personally identifiable information as part of the transaction to process a request for decryption credentials.  Viewer data may be collected by third parties in the delivery of ATSC 3.0 broadcasts apart from A3SA’s decryption credentials transactions.  Please refer to the applicable policies of these third parties for their privacy practices.

A3SA uses the IP address and device identifier to 1) process and fulfill requests for decryption credentials (i.e., to deliver to the requesting receiver decryption credentials that are enabled for that specific receiver), 2) to streamline subsequent requests from the same receiver, and 3) to monitor the performance and efficiency of the proxy server and to troubleshoot and fix problems which might arise.  A3SA does not use or authorize the use of the IP address or device identifier for any other purpose (e.g., marketing to you) and does not provide either one to third parties, nor does it acquire marketing data from third parties to match up to the IP address and device identifier.  A3SA may be legally required to preserve or disclose such information in response to a lawful order of a court or agency of government or law enforcement.

The logs of the A3SA proxy server which include the IP addresses and device identifiers are preserved only for as long as reasonably necessary to fulfill the purposes described above (generally anticipated to be up to sixty (60) days), and are then deleted.


February 26, 2024—Digital Video Recorder Specifications Released for New NEXTGEN TV Devices Electronic Manufacturers Provide Input for Development of Secure DVR Platforms

A new digital video recorder (DVR) specification is now available to licensees of the A3SA content protection technology that is now being deployed throughout the country concurrent with the launch of NEXTGEN TV broadcast channels.  The new specification provides a blueprint for a variety of new ATSC 3.0 recording devices that will allow innovators to develop new products for home networks, insuring the seamless and easy viewing of favorite broadcast TV programs.

“For the past year, we’ve been working in consultation with several electronics companies who are developing devices designed to add new features for NEXTGEN TV viewers, from simple DVRs to more advanced home networking systems.  After considering the various home scenarios, A3SA is pleased to release detailed specifications that will guide companies and soon provide consumers with a wealth of new options for digital video recording and more,” said Ron Wheeler, managing director of A3SA.

A3SA approved the new specifications and rules for secure DVRs, home gateways, and other accessory devices, as well as a newly added alternative method to let viewers securely stream ATSC 3.0 content from such devices throughout their home network.  Developed in consultation with manufacturers and with extensive subsystem prototyping to prove feasibility, the new DVR specifications support multiple product architectures from single components to systems that have devices distributed across a home network.

The DVR specification is designed to work in concert with A3SA’s earlier established Broadcaster Encoding Rules, which govern how broadcasters can use the A3SA security technology with ATSC 3.0 content that is simulcast with corresponding ATSC 1.0 content, allowing viewers to decode and record broadcasts, make unlimited copies without expiration dates, and use common features like pause, rewind and fast-forward.  The A3SA Encoding Rules also prevent downgrading of picture quality when connecting to legacy television sets.

The new A3SA DVR specification supports in-home streaming to applications hosted on common media consumption platforms such as Android, Fire, Roku, WebOS, and Tizen, with iOS support in process.  The spec supports dynamic memory provisioning for media playback (an advantage for consumer devices) and enables developers of new NEXTGEN TV platforms to bring to market innovative new options.

August 21, 2023—A3SA announces a set of “Encoding Rules” its licensed broadcasters must follow for encrypted ATSC 3.0 broadcasts that are simulcast with ATSC 1.0 broadcasts


July 27, 2023—A3SA has approved the issuance of a new Verification Test Suite Addendum for licensed Adopters who implement A3SA’s current (V0.9) Specifications in receiver devices and components intended for consumers, as well as in professional tools intended for broadcasters and other device manufacturers.  The included new V0.9 Test Suite enables the testing of a far higher percentage of the features required by the new Specifications than the previous version did.  This in turn should enable device and component manufacturers to deliver even greater levels of reliability for their products than was previously possible


March  24, 2022— The following documents are now available:
