There will be big “differences” in the transition to ATSC 3.0 compared with the transition from analog to digital ATSC 1.0, Richard Lewis, vice president-technology and research at LG Electronics USA, told the ATSC Broadcast Television Conference Wednesday.
The FCC should refrain from imposing "tech mandates" on the proposed transition to ATSC 3.0 and facilitate "permissionless innovation" for broadcasters, Commissioner Mike O'Rielly said Wednesday at the ATSC Broadcast Television Conference. Along with O'Rielly's keynote, the event had panels on the new standard's chances at the FCC and on the post-incentive auction repacking effort.
ATSC’s S34-1 ad hoc group on ATSC 3.0 video plans to choose a high-dynamic range technology by July 31 for adoption when the next-generation system’s video codec is elevated to the status of proposed standard, Alan Stein, Technicolor vice president-R&D who chairs S34-1, told ATSC’s Broadcast Television Conference Tuesday.
Startup Airwavs.tv plans the late-2016 debut of a protective case for iPhones and premium Samsung smartphones with a built-in DTV antenna and receiver, said CEO Bonnie Beeman in an interview. Trademarked the QuarterBack, the product has advanced to the working-prototype stage, and the company hopes to bow it in time for the holiday selling season, she said. Airwavs.tv plans to introduce the QuarterBack at this week's ATSC Annual Broadcast Conference in Washington, where Beeman is a scheduled panelist.
The FCC promised at last month’s NAB Show to put ATSC 3.0 “on a short leash,” Sinclair CEO David Smith said on a Wednesday earnings call. Once comments and replies have been submitted to the FCC by late June on the multi-industry petition for authorization of ATSC 3.0's physical layer (see 1604200051), Sinclair -- a longtime advocate of getting ATSC 3.0 implemented sooner rather than later -- thinks an ATSC 3.0 rulemaking notice “will go out as part of the normal protocol here,” Smith said in Q&A. “We think it’s reasonable that sometime early first quarter, possibly, of next year, the FCC will grant authority for the industry to move at its discretion” on the voluntary aspects of ATSC 3.0, Smith said. “So we view it just as an incredibly positive sign that the industry is ready to go, and people should start thinking about the business opportunities that are going to roll off the back of 3.0 over the next five to 10 years.” Smith regards the introduction of ATSC 3.0 as “just an enormous, life-altering event” for the broadcast industry, he said. “The NPRM should be out fairly soon,” Smith said. “Remember, this is just a procedural kind of process they go through, where they ask for comments and then they issue the NPRM, and everyone files their views of the world, and then they consider and they make a decision,” he said. “So we view this as kind of fairly routine.” FCC representatives didn’t comment.
The “common framework” for ATSC 3.0 audio “provides immersive and personalizable sound for television,” and is “not compatible with the audio system used” in the current ATSC 1.0 service. So said the first of three documents describing the “common elements” of ATSC 3.0 audio “intended to be used in conjunction” with the Dolby AC-4 codec summarized in the second document, and MPEG-H described in the third.
Though the ATSC 3.0 transition plan has gotten a favorable reception from some broadcasters and FCC Chairman Tom Wheeler (see 1604200051), questions abound about how broadcasters transitioning to the new standard will interact with pay-TV providers and smaller broadcasters, broadcast and cable attorneys told us last week.
Sony landed a U.S. patent Tuesday for a “method and apparatus for transmitting a-priori information in a communication system,” Patent and Trademark Office records show. A-priori information is that which is based on scientific deduction rather than observed, empirical data. The patent (9,326,295) is based on a December 2014 application and lists as its inventor Luke Fay, senior staff engineer at Sony Electronics in San Diego. Fay is chairman of ATSC’s S-32 specialist group that framed ATSC 3.0's physical layer, which is now before the FCC as an authorization petition (see 1604130065). Fay also is vice chairman of ATSC’s Technology Group 3, which is supervising development of the overall ATSC 3.0 standard. “During the last decade, terrestrial broadcasting has evolved from analog to digital,” Fay’s patent says. “There exist several wideband digital communication techniques depending on a broadcasting standard used,” including OFDM, which is “a method of encoding digital data on multiple carrier frequencies and is used in applications such as digital television and audio broadcasting, DSL Internet access, wireless networks, power line networks, and 4G mobile communications,” the patent says. Though the patent doesn’t say so, OFDM is the modulation system used in ATSC 3.0 and has been used for years by Europe’s DVB consortium. “Current digital broadcasting systems use fixed knowledge of a channel bandwidth at a receiver,” the patent says. “In addition to the specific information about the communications technology used, the receiver needs the channel bandwidth or a sampling frequency to demodulate received signals. Due to technical advancements, the channel bandwidth and the sampling frequency may change over the years. As recognized by the present inventor, there is a need to facilitate changes in channel bandwidth and/or sampling frequency.”
The FCC Media Bureau as expected issued a public notice Tuesday seeking comment on the multi-industry petition for authorization of the physical layer of ATSC 3.0 (see 1604200051). The petition asks the FCC to approve ATSC 3.0 as an “optional standard” for broadcasting and approve rule changes to allow simulcasting during the deployment of ATSC 3.0. Broadcasters told us at the NAB Show that the commission's seeking swift comment on the petition is a positive sign but not a guarantee of further FCC action. Comments are due May 26, replies June 27, said the Tuesday notice in Docket 16-142.
The FCC Media Bureau has put together a draft order that would let the National Cable TV Cooperative (NCTC) file complaints, American Cable Association President Matt Polka told us Monday as the FCC hosted the second of two workshops on the state of the video market. ACA had sought such an order (see 1507020018) to help small multichannel video programming distributors gain some leverage in negotiations with major programmers. The workshops, plus the FCC's now-closed notice of inquiry into the challenges for independent and diverse programmers, could help push the agency on such issues before it as a buying group rule change and its current NPRM looking at changes to retransmission consent rules, Polka said. The FCC didn't comment.
