Tests show ATSC 3.0 “can provide robust reception of data at all vehicular speeds,” concluded a paper by Sony engineers Luke Fay, Graham Clift and Fred Ansfield. “This field test shows that broadcasters can transmit both high throughput stationary services as well as robust automotive services simultaneously to target a diverse set of receiving devices,” it said. “Delivery of data of any kind (infotainment, software updates, navigation maps, etc.) is robust and reliable.” Automotive field tests Sony conducted in the fall with Pearl TV in Phoenix and News Press & Gazette in Santa Barbara, California, found NextGenTV can be a viable broadcast service for delivery of “robust passenger infotainment” to vehicles and “easily transmit software updates and information to fleets" of vehicles, the company said Wednesday. Prototype Android and Sony devices were involved.
The Advanced Warning and Response Network Alliance wants to comment on FCC proceedings arising out of the Reliable Emergency Alert Distribution Improvement Act (see 2012040043) on a report on emergency alerting over streaming media, it said in a filing posted in docket 15-94 Tuesday. AWARN Alliance Executive Director John Lawson, ATSC President Madeleine Noland and other members of the AWARN Alliance Steering Committee met virtually with Public Safety Bureau Chief Lisa Fowlkes and staff Thursday. The alliance wants to “re-engage” with “key federal agencies and non-government organizations involved in alerting,” to discuss using 3.0 in emergency communications and the development of “model voluntary agreements” between TV stations and alert originators. Fowlkes listed “responding to directives from Congress in the READI Act” and “convening a new Communications Security, Reliability and Interoperability Council,” as priorities for the bureau, the filing said.
NAB, E.W. Scripps and Tegna asked the FCC to clarify how FCC licensing rules affect TV stations multicasting during the ATSC 3.0 transition, in replies for Monday night’s deadline in docket 16-142. “The clarification and rule changes NAB seeks in this proceeding are ministerial in nature and intended only to ensure that the Commission has a consistent regulatory framework,” said NAB. Recognizing or codifying rules around broadcasters hosting programming streams for other stations is needed to clarify the arrangements don’t create attributable interests for ownership purposes, and that the stream’s originator is responsible for ensuring it complies with FCC considerations such as kidvid and emergency broadcast rules, Tegna said. The clarification would “provide regulatory certainty and efficiencies that would facilitate the deployment of ATSC 3.0 technologies,” said Scripps.
The FCC approved 3-2 rules for broadcaster distributed transmission systems -- also called single frequency networks -- said an order Tuesday. Commissioners Jessica Rosenworcel and Geoffrey Starks dissented in part from the order that's seen as important to the ATSC 3.0 transition over concerns that rules allowing broadcaster “spillover” will interfere with the use of TV white spaces for unlicensed devices. This “threatens to disrupt” a “careful balance” over the white spaces by “moving too quickly,” Starks said. The order replaces the current restriction on DTS signals spilling beyond a station’s service area beyond “a minimal amount” with a hard number dependent on the type of station. The new “bright-line rule” allows for more spillover and clarifies the requirement. That’s a change from the NPRM, which the order said “failed to account for the additive effect of multiple DTS transmissions and thus underestimated the potential interference impact of the proposal.” Starks and Rosenworcel had advocated for an expedited waiver process for broadcasters that sought to use DTS systems, an approach also pushed by Microsoft and New America's Open Technology Institute. “I would have preferred a more fine-tuned approach that would have allowed us to better gauge the effects of these systems on other services that use these airwaves,” said Rosenworcel. The agency is “confident” the order will result in less interference than the proposal. The order won't let stations expand their reach beyond current limits, said Chairman Ajit Pai, whose last full day was Tuesday. "Any DTS transmitters must stay within the broadcaster’s authorized or hypothetical maximum area and must be necessary to ensure better local transmission -- not intended to extend coverage beyond the authorized area." The order “will permit stations to reliably reach viewers that could not otherwise be served by a single transmitter architecture, which is so important in rural and remote areas, in terrains with gaps in coverage, and in urban settings, often in communities with traditionally underserved populations,” said America’s Public Television Stations General Counsel Lonna Thompson in an emailed statement. “We're pleased that the Commission adopted this change to the rules on Single Frequency Networks, since it will help broadcasters roll out NEXTGEN TV more quickly and more efficiently,” said broadcast consortium Pearl TV.
A distributed transmission system signal “is a broadcast TV signal by any other name,” and TV white space rules should apply, said Microsoft in a call with aides to FCC Commissioner Jessica Rosenworcel Tuesday, per a filing posted in docket 20-74 Friday. The FCC should maintain existing rules and institute an expedited waiver process for ATSC 3.0 stations that seek to allow the DTS signal to extend a minimal amount beyond their current maximum service areas, Microsoft said. The agency's DTS item has sufficient votes for approval (see 2101050063).
TCL has no current plans to make its TVs compatible for ATSC 3.0 (see 2101130068), a virtual CES event heard. The company has no plans to support the 3.0 standard in 2021, a spokesperson said Wednesday. The company will bring the TCL Home app, available in some markets now, to the U.S. this year, said Aaron Dew, TCL North America director-product development. TCL’s Android and Roku TVs will be controllable through the app, allowing them to manage the company’s smart home appliances from TVs, too. The company is also eyeing 5G (see 2101130072).
NextGenTV can “evolve over time,” said ATSC President Madeleine Noland. “It’s not something that’s so static, like today’s television system.” ATSC 3.0's framers decided to “design it for 4K right now, knowing that we can upgrade to 8K basically at any time,” she told the virtual CES Tuesday. South Korean broadcasters recently started “field trials” delivering 8K over 3.0 using the existing H.265 video codec, she said. Noland predicted consumers who adopt NextGenTV will “get addicted” to the platform's HDR and wide color gamut capabilities. Executives also discussed 8K. Fox Sports used three 8K cameras when it televised Super Bowl LIV Feb. 2, said Michael Davies, senior vice president-field and technical operations. “It paled in comparison, somewhat, to the 102 other cameras we had, yet we did do the whole thing in HDR." Davies last visited Japan just before the pandemic, “and I was embarrassed to say we were still producing shows in 720p SDR,” he said. The Japanese "weren’t even talking about 4K at that point," he said. "They were talking about 8K.”
TCL confirmed U.S. pricing for its TCL20 5G smartphone, which will sell in the U.S. for under $300. Product Marketing Manager Josefina Fuster said at a virtual CES event that the company’s goal is to deliver “affordable 5G without compromising.” The company will launch its first 5G tablet and its first foldable phone this year, Fuster said Wednesday. TCL has no current plans to make its TVs compatible for ATSC 3.0 (see 2101130070).
CTA forecasts that the consumer tech industry will ship 800,000 NextGenTV sets this year, for 167% growth from 2020's 300,000 units, Vice President-Research Steve Koenig told a live ATSC webinar. It projects 12 million ATSC 3.0-compatible sets will be shipped in 2024, for 31% of all TV unit volume, he said.
The draft ATSC 3.0 distributed transmission system order “will adversely impact the availability of television white spaces (TVWS) spectrum in rural areas and undermine the expansion of rural broadband access,” said Microsoft in a call with aides to FCC Commissioner Nathan Simington Tuesday, per a filing posted Friday in docket 20-74. “The current DTS signal spillover standard should be maintained,” and any more than “a minimum amount” should be permitted via a case-by-case waiver process, the filing said. The DTS has sufficient votes to be approved (see 2101050063).
