  26. 26. [NAB 2017 핵심 키워드] ATSC 3.0, 우리나라를 시작으로 세계로 확산되길 기대 2017.02.23. ATSC 3.0을 차세대 미국 지상파 방송 국가표준으로 채택
  27. 27. 미국의 ATSC 3.0 전환 5대 원칙 ATSC 3.0 1. Voluntary Use : Proposes to authorize voluntary use of ATSC 3.0 transmissions and to incorporate the relevant portions of the new standard into the Commission’s rules. The NPRM tentatively concludes that a Next Gen TV tuner mandate for new television receivers is not necessary at this time. 방송사, 가전사 등 방송분야 참가자들이 자발적으로 도입하는 것을 원칙으로 함. 새롭게 출시되는 TV에 ATSC 3.0 칩셋을 의무적으로 탑재할 필요는 없음.
  28. 28. 미국의 ATSC 3.0 전환 5대 원칙 ATSC 3.0 2. Local Simulcasting : Proposes to require “local simulcasting” for stations that choose to deploy Next Gen TV so broadcasters can continue to provide DTV service using the current ATSC 1.0 Standard at the same time that they offer ATSC 3.0. This approach will minimize disruption to consumers by ensuring that they will still be able to use their existing TV sets, which have only current-generation DTV and analog tuners. 기존 DTV 1.0 시청자들의 혼란을 최소화 할 수 있도록, ATSC 3.0 방송을 시작하기로 한 방송사들은 ATSC 1.0 DTV도 동시방송(Simulcast) 하는 것을 원칙으로 함. * 우리나라도 현재 ATSC 1.0 DTV와 ATSC 3.0 UHDTV 동시방송(Simulcast) 중임.
  29. 29. 미국의 ATSC 3.0 전환 5대 원칙 ATSC 3.0 3. MVPD Carriage : Proposes to require that MVPDs continue carrying broadcasters’ DTV signals, using ATSC 1.0, but not to require them to carry ATSC 3.0 signals during the period when broadcasters are voluntarily implementing ATSC 3.0 service. The NPRM also asks about issues related to the voluntary carriage of ATSC 3.0 signals through retransmission consent. MVPD는 방송사들이 자발적으로 ATSC 3.0 서비스를 도입하는 기간에도, 계속해서 ATSC 1.0 DTV 신호를 전송함. 다만, ATSC 3.0 신호재전송 이슈에 대해서는 공감대 필요. * MVPD(Multichannel Video Program Distribution·다채널방송사업): 지상파 방송을 제외한 케이블TV·위성방송·VOD·MMDS/LMDS(무선케이블TV)·IP-TV 등 다채널 영상미디어사업
  30. 30. 미국의 ATSC 3.0 전환 5대 원칙 ATSC 3.0 4. Service and Interference Protection : Asks for comment on whether Next Gen TV transmissions will raise any interference concerns for existing DTV operations or for any other services or devices that operate in the TV bands or in adjacent bands. ATSC 3.0 서비스를 도입함에 있어서, 동일채널 또는 인접채널에 서비스되고 있는 기존 ATSC 1.0 DTV 서비스에 대한 어떠한 간섭도 주지 말아야 함.
  31. 31. 미국의 ATSC 3.0 전환 5대 원칙 ATSC 3.0 5. Consumer Protection and Education : Tentatively concludes that television stations offering ATSC 3.0 should be subject to the public interest obligations that currently apply to television broadcasters and asks for comment on whether broadcasters should be required to provide on-air notifications to educate consumers about Next Gen TV service deployment and ATSC 1.0 simulcasting. 기존 ATSC 1.0 DTV에서 적용 받고 있는 “공익 의무”를 ATSC 3.0을 도입하는 방송국에도 그대로 적용함. ATSC 1.0 동시방송에 대한 시청자 안내 고지, ATSC 3.0 기반 차세대 방송(Next Gen TV) 서비스에 대해 방송 온에어를 통해서 시청자들에게 충분히 알려야 함.

Spectrum Repack & SFN Transition Scenarios for ATSC 3.0 Migration • Assumes re-use current RF channel • Staying on-air will require careful planning, coordination and some effort • An incremental change over is likely, as 3.0 TV’s and consumer devices become available and viewers change to 3.0 • Two scenarios: • Single owner with two stations in same market • Multiple owners, single station each in same market [출처] GatesAir, Transmission Site Planning for ATSC 3.0, in NAB 2017.

  94. 94. Spectrum Repack & SFN Transition Scenarios for ATSC 3.0 Migration: Multiple Owner, Multiple Stations • Lighthouse Station Concept • Proposed by some industry experts – suggests a temporary channel-sharing partnership featuring a “Lighthouse” Station • One station, the “lighthouse” converts to ATSC 3.0 first • That station seeds the market with programs form all stations in the market • The other stations make unused capacity collectively available to replicate the Lighthouse station’s ATSC 1.0 signal, while keeping their own programs • After some time, after viewers start watching 3.0 other stations switch to 3.0 until they are all on 3.0 • When the last station switches over, ATSC 1.0 will no longer exist in that market [출처] GatesAir, Transmission Site Planning for ATSC 3.0, in NAB 2017.

  113. 113. Keynote 내용 요약 (1/3) 방송과 관련된 낡은 규정은 적극적으로(aggressively) 현대화(modernize)하고, 불필요한 규제(unnecessary red tape)는 제거하여, 시청자들에게 더 많은 가치를 제공할 수 있도록 방송사들에 자율성(more flexibility)을 줄 것임. FCC 미디어 관련 규제가 1,000분량이나 있는데, 불필요한 규칙을 없애고(get unnecessary rules out of the way), 규제의 거미줄(cobwebs)을 간소화하라고 오늘 아침에 공개적으로 지시했음. 미래부 방송기술정책연구반 망중립성 이슈 다뤄 졌음 5월 18일부터, 방송/케이블/위성을 포함하는 FCC 규제에 대한 포괄적인 검토(Comprehensive review) 시작할 계획 - 방송사는 반드시 허가 받은 지역 내에 Main Studio와 그 인근에 송신소를 설치해야 함. 제2차 세계대전 시대의 규칙, 일반 대중들에게 전달되는 정보를 통제하고 드나드는 사람과 물리적인 파일(files) 들을 감시하기 위해서 만들어 짐. - 지금은, 온라인을 통해서 모든 것들이 전자적(electronics)으로 이루어지고, 심지어 이러한 규제를 받지 않는 소셜 미디어들과 공정하게 경쟁하는 데 걸림돌이 되고 있음.
  114. 114. Keynote 내용 요약 (2/3) 미디어 소유권 규정(Media ownership regulation)에 대해서도 완화될 것임을 시사. 개인적으로, 라디오는 어릴 적 더 넓은 세상과 연결되는 통로(medium)였음. 좋은 기억이 있는 듯.  AM Revitalization을 강조 1단계 지원사업을 통해서, 1100 군데 AM 방송국들이 FM Translator 허가(license)를 신청하여, Nearly 95% 정도가 허가를 취득했고, 전체 1/5에 해당하는 AM Station 들의 서비스 권역이 늘어남. Class C와 Class D Station에 대한 FM Translator 지원사업을 올해 중으로 실시 예정. AM Class A Station clear-channel stations — 10 kW to 50 kW, 24 hours. Class B Station regional stations — 250 W to 50 kW, 24 hours. Class C Station local unlimited-time stations — 250 W to 1 kW, 24 hours. Class D Station current and former daytimers — Daytime 250 W to 50 kW, nighttime under 250 W or off-air.

  115. 115. Keynote 내용 요약 (3/3) Incentive Auction과 주파수 Repack 관련해서, 모든 정책 결정에 동의하지는 않지만 FCC Staff 들의 엄청난 노력의 결실이라고 평가. 앞으로 남아있는 일도 많음을 언급. 987개의 TV 방송국은 39개월 내에 새롭게 할당 받은 채널로 이동해야 함. 이를 위해서, FCC, 방송사, 통신사업자가 긴밀이 협력해야 할 것임. 현지 NAB나 ATSC의 평가, 역사상 유례없이 방송 친화적인 인물이 FCC 의장이 되었다. 지금이 그동안 방송산업에서 그동안 해결하지 못한 숙원 사업을 추진하기 위한 절호의 기회. 특히, ATSC 3.0 기반 Next Gen TV에 대해서도 관심이 높고 긍정적으로 생각함.
