지상파 UHDTV가 2017년 5월 31일부터 수도권을 중심으로 송출되기 시작한지도 벌써 1년 가까이 되었으며, 수신되는 지역을 조금씩 확대하여 2021년까지는 전국을 커버하고자 진행되고 있다. 지상파 UHDTV는 직접수신이나 방송공동수신설비를 활용하여 수신율을 높이고자 하나, 현재까지는 "방송채널별 변복조형 신호처리기"의 보급이 활성화되지 못하여 시일이 조금은 미루어질 것으로 예상된다. 특히 지상파 UHDTV의 장점을 발휘하기 위해서는 해결해야 할 난제가 여러 가지가 있다. 본 논문에서는 지상파 UHDTV의 수신뿐만 아니라 ATSC3.0이 갖고 있는 다양한 특성과 장점을 알아보면서 제언을 하고자 한다. 결과적으로 UHDTV는 국민에게 무료 보편적 서비스로 당연히 제공되는 방송이 맞지만, 더욱 다양한 서비스(Wake-Up 이나 홈포털, VoD 등)가 무료나 유료로 제공되기 위해서는 지상파 방송사가 정부, TV제조사나 통신망 사업자 등과 상호협력이 필요함으로 지속적인 대화를 통한 해결방안을 찾아야 할 것으로 보인다.

Domestic free TVs play roles as for contents provider and TV station : they need to acquire not only ad revenues but also distribution revenues from internet service, cable channel and DMB. It is however doubtful to keep the windowing of programs through the different windows due to recent decrease of ad revenues of the stations. Therefore, the purpose of this study is to search for the mechanism of windowing of free TV's programs and the strategy of the distribution. As a result, the life cycle of the broadcasting programs is so short to be distributed within 7 days, Regarding the windowing, there are at first the strategy increasing the accumulated revenue by the diversification of the windows ; secondly, the strategy focusing on the prospective window neglecting the holdback. It is necessary to choose to take the appropriate strategy by the particularity of each program and the market background.

This study looked into coping strategies of local terrestrial broadcasting companies in the media market, since the introduction of comprehensive programming channels was confirmed. Local terrestrial broadcasting companies vulnerable to market competitiveness are driven more out to the difficulty of survival in a limited advertising market with the advent of comprehensive programming channel. and Local terrestrial broadcasting receive discriminative application than comprehensive programming channel. They have reverse discrimination in must-carry, broadcasting area, programming regulation, advertisement regulation, broadcasting development fund. Hence, Local terrestrial broadcasting needs diverse countermeasures at difficult media circumstances. Above all, Competitive content reinforcement is desperately needed. That's why content distribution structure needs diversification. And, It is necessary for local terrestrial broadcasting companies to diversify the content distribution system. As a way to expand distribution structure of local broadcasting, the introduction of local programming regulations for total amount will be highlighted in the nationwide network program. The mandatory policy that programs produced by local terrestrial broadcasting companies will be broadcast regularly in prime time through a nationwide network is an example. In addition to developing high content independently, 2nd Multiple channels of distribution is needed. It has to be supplied to various platforms including local broadcasting, SO and etc. In addition, it is necessary to activate regional co-production program between local terrestrial broadcasting companies and regions. Time rate between central stations and local terrestrial broadcasting companies must be distributed practically. And also, local terrestrial broadcasting companies in addition to ad revenue model to themselves and their own businesses by expanding the sponsorship to strengthen the competitiveness will have to nurture self-sustaining. Moreover they must have enlarge economy of scale through widen of broadcasting area.

브로드밴드 네트워크의 발전으로 네트워크를 통해 콘텐츠를 제공하는 TV포털이나 IPTV 서비스가 활성화되고 있으며 시청자들은 온디멘드 서비스에 익숙해지고 있다. 하지만 지상파 방송사는 방통 융합 서비스의 핵심이라고 할 수 있는 양방향 네트워크를 갖고 있지 않으므로 증가하고 있는 시청자의 온디멘드 서비스 요구에 적절히 대응하지 못하고 있는 실정이다. 따라서 지상파 방송사의 입장에서는 상대적으로 운용비용이 많이 드는 인터넷과 같은 양방향 네트워크의 전송 효율을 높이기 위해 온에어 DTV 채널을 기반으로 인터넷을 접목하여 TV와 PC 나아가서는 모바일 단말과 같은 다양한 단말에서 콘텐츠와 관련 데이터를 공유할 수 있는 DTV 기반의 크로스미디어 서비스가 적합하다. 이에 본 논문에서는 이러한 크로스미디어 서비스를 제공하기 위해 필요한 콘텐츠 제작 요소기술과 온에어와 인터넷을 통해 콘텐츠와 관련 정보를 송수신하는 요소기술을 제안하는 바이다.

Platform operators adopted ATSC standard send only their own channel program schedule information, so in order for the viewer to see other channel information, they have to tune the channel to the other. This issue arises from the operators' lack of bandwidth and the business interest conflicts between the platform operators. This paper guides how ATSC standard could be used within Xlet based application to display other channel information through the ISG (Integrated Scheduling Guide) technology via interactive return channel services. Its own channel information can be displayed by using on-air PSIP (Program and System Information Protocol) data.
