Silicondust Becomes ATSC 3.0 Certificate Authority
Silicondust, a TV tuner manufacturer, has become an official ATSC 3.0 Certificate Authority, establishing an independent certification path for broadcasters deploying NextGen TV. The company will issue its own "FullTrust" and "AskTrust" certificates and positions itself as an alternative to the A3SA consortium of major station groups. Silicondust also announced a patent-pending offline validation system intended to keep stations on air during emergencies. The move follows allegations of anti-competitive behavior by A3SA and public concern about an A3SA plan dubbed "High Noon," disclosed in an FCC filing by Weigel Broadcasting. Silicondust President Nick Kelsey and industry sources framed the change as opening a closed certification process and creating more options and flexibility for broadcasters.
Creates an alternative to a consortium-controlled ATSC 3.0 certification process, potentially reducing gatekeeper control over NextGen TV security credentials and affecting broadcaster workflows, costs, and emergency resilience.

TiVo Builds Cross-Platform Advertising Signal Layer
State of Streaming reports that Xperi (TiVo) is positioning itself as an invisible infrastructure layer that connects TV streaming, smart TVs and in‑car dashboards via persistent identifiers and ACR data licensing. In the U.S. TiVo Ads announced a household-level identifier that bridges living-room streaming to in‑car dashboards using DTS AutoStage (now powering 14 million vehicles). In the U.K. TiVo launched an independent Automatic Content Recognition (ACR) data licensing product that pools signals across multiple smart TV brands (Sharp, Bush, Panasonic, Techwood) and is explicitly platform-agnostic. Xperi emphasizes it does not own consumer relationships, preserving OEM partnerships that provide cross‑environment signals; Samba TV is named as a measurement/verification partner. The piece highlights scale arguments (110M+ North American vehicles with HD Radio receivers) and affluent in‑car audiences for targeted advertising (BMW/Mercedes buyer income stats).
