인터넷의 발달과 웹 어플리케이션의 활성화로 Internet Connected TV가 차지하는 비율이 점차 늘어나고, 스마트폰의 선풍적인 인기와 시장의 영향으로 디지털 TV에도 Smart TV의 바람이 불고 있다. Smart TV의 기술을 수신기 관점에서 살펴보았을 때, 방송과 웹이라는 두 가지 분야의 기술과 표준을 생각할 수 있다. 이에, 방송 분야에 대해서는 북미 ATSC 2.0, ATSC PT-3, 유럽 HbbTV 와 DVB-IPTV, 그리고 한국의 OHTV를 표준 관점에서 서비스 및 기술을 서로 비교하고, 다음으로 웹에 대한 기술과 표준화는 W3C의 HTML5, Web and TV 그리고 MPEG에서의 DASH를 살펴보기로 한다.

These days many DLNA home media network services start in home network area. DLNA networking softwares included in DLNA media devices contains all of server, renderer and controller functions. But a home media device in home media network environment not uses all of DLNA functions but uses only limited functions. Using all of integrated DLNA functions wastes networking and processing resources especially in home media network, because a home media device uses very limited functions. For example, a smart-TV has a main role of playback and a network attached storage has a main role of media content storage. In this paper, we analyze integrated DLNA networking softwares and design DLNA software models representing each home media device so as to utilize device resources efficiently. And we implement DLNA softwares for smart-TV and smart-phone and test resource efficiency.

The recent broadcasting environment has shifted to embrace multimedia and multi-channel features through terrestrial, satellite and cable media. This has multiplied the number of broadcasting programs. With the information on a myriad of programs provided to TV viewers, information overload occurs, and thus, the TV viewing environment is shifting to one where viewers cannot select programs passively. Thus, a growing need is emerging to ensure a personalized electronic program guide (EPG) to help individuals select TV programs according to their taste. This paper presents a personalized EPG that enables a purpose-oriented broadcasting service to provide personalized broadcasting programs in tune with the user's requirements and preferences.

This study investigated a current situation of cable TV in order to seek and suggest cable TV's competitive superiority in the era of multiplatform media marketplace. This study suggested cable TV's direction from two aspects, short-term and mid and long-term strategies. As a result, it recommended that cable TV industry need to establish content circulation representatives, and reinforce multiformat contents suitable for various multiplatform uses, digital cable promotion, production of SO's originated programs, HD VOD, bundling services and diverse programs. As a long-term strategy, this study also suggested cable TV industry need to cooperate with smart TV industry in order to widen openness of its platform, and to provide not only diverse contents but also applications by offering two-way, mobile, and on-demand contents and services. Finally, this study proposed cable TV is needed to move towards a comprehensive media portal, which is a contents aggregator with the aforementioned business strategies.

Due to rapid convergence trends in the digital pay TV market, differentiation among the competing medias decreases and substitutability is increasing. The current study aims to explain the effect of service substitutability among competing media on the size of domestic digital pay TV subscribers. For the analysis, the Lotka-Volterra model, an ecological competitive diffusion model, was used to obtain the basic model for a simulation study. A simulation was performed by adjusting independent variables of substitutability to estimate the size of subscriber for particular media. The relationship between the digital cable TV and the IPTV is identified as a predator-prey relationship and the digital cable TV is found to be superior to the IPTV. The simulation results showed that the increase of convergence and substitutability result in the decrease of the entire media market. Especially, the IPTV is estimated to face the greatest loss in this context.

스마트폰 열풍이 세간에 뜨거운 관심을 받고 있던 즈음에 스마트 TV라는 다소 생소한 단어가 IT업계를 술렁이게 하고 있다. 거대 기업 애플과 구글이 전세계의 스마트폰과 스마트TV에 대한 장악력을 높이고 있고, 이에 맞서 국내에서는 삼성과 LG가 가세하여 스마트 기기에 대한 플랫폼 및 콘텐츠 지배력을 가지고 경쟁을 벌이고 있다. 유무선망이 통합되고 콘텐츠의 융합화가 가속화되면서, 개별 서비스 단위에서 융합서비스로 트렌드가 변화하고 있으며, 스마트 TV도 모바일과의 연계를 통해 웹 서비스 및 소셜 네트워크와 융합된 다양한 콘텐츠를 제공하려는 추세이다. 스마트TV는 단순 TV서비스에서 모바일과 연계하여 N-스크린 서비스로 발전하고 있고, 플랫폼에 대한 경쟁력이 약한 국내 기업의 경우에는 플랫폼 경쟁력을 강화하면서 동시에 서비스의 차별화를 통해 경쟁력을 갖추어 야 할 것이다.

From the perspectives of regulation and convergence, several debates on the industrial definition of smart TV service in the Korean broadcasting and communications market are currently in progress. The most heated controversy mainly depends on whether smart TV is controlled under broadcasting regulations or under communications regulations. This Korean- specific problem is summarized in regulation fairness or asymmetric regulations between smart TV and IPTV operators. Although both operators utilize very similar technology and share the same business model, the regulations for only smart TV operators are unfettered. This would be an intrinsic cause that prohibits fair competition in the new converging market. Currently we confront the matter of asymmetric regulations between smart TV and others including IPTV or ISP. The purpose of this study, thus, is to provide the strategic, regulatory guidance and theoretical definitions on smart TV service, as one of converging services, based on a qualitative approach through subjectivity methodology. The study identifies three issues net neutrality, regulation fairness and new media and new market and proposes desirable promotion plans regarding those issues. The study draws lessons learned through a Korean smart TV case and provides directions to strategic-policy studies for future emergent converging services.
