TV의 발명은 실로 놀라운 것이었다. 실제 오늘날의 TV모델을 발명한 발명가는 영국의 존 로지 베어드라고 한다.1926년 그가 발표한‘Falkirk’라는 이름의 장치는‘움직이는 영상’을 전달하는 기능을 갖춘 최초의 TV 모델이 됐다. 이를 기본으로, 1929년 영국 BBC 방송이 세계 최초로 텔레비전 방송을 시작했고 하니, TV 방송의 역사는 대략 75년 정도 된 연세 지긋하고 연륜이 넘치는 기술이 됐다고 할 수 있다. 이후 흑백에서 컬러로, 두꺼운 브라운관에서 액정화면으로, 섬세한 영상의 HDTV 기술과 위성방송 등으로 숨 가쁘게 바뀌어왔다. 이런 과정을 통해 사람들과 뗄래야 뗄 수 없는 기본 영상정보 전달장치가 됐으며, 수많은 정보들이 이 TV를 통해 전달되고 있다.

HbbTV는 Hybrid broadcast broadband TV의 약자로서 기존 방송과 함께 브로드밴드(Broadband) 웹 콘텐츠를 거실에 있는 TV 화면에 가장 효과적으로 전송하여 보여 주고, 사용자와 상호 작용 할 수 있도록 유럽에서 시작되어 만들어진 표준이다. HbbTV 표준은 소수의 새로운 기술 요소만 새로 도입하여 표준을 만들고, 대부분 이미 존재하고 검증된 특정 표준을 그대로 재 사용하였기 때문에 개발 비용 및 특히 적시 출시(time-to-market)에 큰 강점을 가지고 있다. HbbTV는 EBU "hybrid broadcast/broadband systems"의 요구 조건을 완전히 만족하는 표준이 되었다.

Smart TV sareequipped with an operating system and combined with internet functionality. They can use various apps and contents, and provide personalized and interactive services. However, the Internet connectivity of smart TVs has several security vulnerabilities that can cause significant personal and social harm. Therefore, it is necessary to develop a smart TV with a higher level of security than is currently available. In this study, we analyze consumers' purchase intention for smart TVs with security reinforcement by applying the UTAUT2 model. The results are as follows. Firstly, it was found that performance expectancy, social influence, facilitating conditions and price value, as important variables under the existing UTAUT2 model, have significant effects on purchase intention. Secondly, effort expectancy did not have a positive impact on purchase intention. Thirdly, there was a moderating effect of gender on social influence. According to the results of this study, social influence has the most powerful effect on the purchase intention of smart TVs with security reinforcement. Therefore, in order to improve the purchase intention of smart TVs, it is necessary to expand the publicity activities designed to promote the necessity and importance of reinforcing the security of smart TVs and make them easier to use.

Smart TV is expected to take the center stage of the recent "smartization" trend in IT and consumer electronics as it performs a hub for various smart IT devices, such as smart phone, smart pad, PC, etc. It is distinct from traditional TVs or even IPTVs in the sense that it provides immersive and interactive experiences via apps downloaded through TV app store. Smart TV could serve as a new intermediary device between other smart devices and the Internet. While it started experiencing a rapid growth, little research has been conducted to understand this emerging technology in terms of its user acceptance and adoption by users. The current research attempts to fill the gap in the field by examining factors and processes for this new technology to be adopted by users. This paper draws on theories of IT acceptance and use, such as the "Unified Theory of Acceptance and Use of Technology", to investigate factors affecting "intention to use" of smart TV. The proposed research model is analyzed using the structural equation modeling approach. Findings show that such factors as innovativeness, switching cost, switching benefit, service interface, and user interface affect users' intention to use smart TV, through effort expectation, performance expectation, and social influence. Theoretical and managerial implications are discussed.
