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.

This paper describes a digital video recorder-based approach to realising interactive programmes on digital television. So far, it is very difficult that the most interactive programmes included the vast quantities of the content, whatever it is data or HD-ready broadcasting, are broadcasted on digital television via the set-top box. Furthermore it is not possible to envisage until IPTV was appeared. Even though IPTV makes possible for streaming the interactive services via broadband, it is not easy to receive tremendous contents for interactivity as set-top box at once. In this paper it will suggest an effective solution to resolve the download dilemma for the interactive services on DTV by employing the set-top box fitted with digital video recorder.

VOD Service, which has established a solid foothold as a profit model of digital broadcasting companies, is emerging as a key application of the N-screen technologies and services. In the circumstance, broadcasting companies are trying to promoting their VOD services by providing mobile services for improving the VOD service usability. The paper introduces a VOD mobile app (of a domestic digital cable broadcasting), which includes the functions of promoting the VOD programs and events printed on a VOD guide book, directly transmitting the information (e.g., book-marking and remote-control signals) to a set-top box, and watching the video contents stored in the mobile device on TV.

This study investigates the basic elements of film acting based on Lee Strasberg's emotional memory. Acting in Korean film and TV drama often meets difficult circumstances. Therefore, I strongly suggest Lee Strasberg' American Method to film actors and students. This method refers to affective memory that Lee Strasberg devised for film acting at the Actors Studio. Another main point of this method is to overcome difficulties created from the camera use and shooting process. It is evident practicing affective memory would help actors perform better in their field.

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.

Despite the recession of the global market, the domestic electronic appliance companies dominated TV market in North America. They took both the premium and mid-priced product market and achieved both profitability and volume due to strong product competitiveness and brand power. Despite doing well in the North American market, the domestic TV manufacturers are worried about product development, marketing and sales strategies to remain the continuous competitiveness in the TV market. This study proposes the a sales prediction model of electronic appliances using sales data of S company from the North American market. We develop the sales prediction models based on multiple regression analysis and artificial neural network and compare two models. Especially, this study analyzes the relevance between the TV sales and TV main features in order to improve the price competitiveness or improve the value of TV products.

The purpose of this study is to investigate the change of the type and characteristics of Korean sports star TV commercials and to deeply investigate the relationship with social contexts and backgrounds. In order to solve the purpose of this study, This study collected data of 38,517 TV advertisements from 1970 to 2009, and analyzed data of 146 media contents. The results obtained are as follows. First, Korean sports star TV commercials showed a steady increase with the economic growth and media development of Korea, and the percentage of total TV advertisements was low. Second, sports star TV advertising plays a role of expanding the sports industry, but it shows that the efficiency of relationship persistence decreases without social situation and public recognition.

Networked Digital Recorder(NDR) Platform is a system that owns contents jointly between tv viewers connected by the broadcast broadband convergence network. NDR suggests a new content distribution chain model that users can receive broadcast contents, share contents and sends contents by convergence network. This paper looks at the system requirements, service model and the overall system architecture of NDR platform.

최근 발행한 LG경제연구소 보고서에 의하면 올해 연말부터 시작될 디지털 위성 방송은 풍부한 채널, 선명한 화질 및 음향 다양한 부가 서비스를 제공할 것으로 보이며, 가전, 컨텐츠, 전자상거래 등 관련 비즈니스에도 상당한 파급효과를 몰로 올 전망이라고 설명했다. 위성, 지상파, 케이블 방송 등은 TV방송을 수신하는 방식에서 차이점이 있다. 위성방송은 방송국에서 전송한 방송신호가 위성을 통해 시청자에게 전달되며, 시청자는 접시 형태의 안테나를 TV에 연결함으로써 방송신호를 수신할수 있다. 반면 지상파 방송은 방송국에서 전송탑을 통해 전송한 지상파 방송신호를 옥외 혹은 옥내 안테나를 통해 수신하는 방식이며, 케이블 방송은 동축 케이블을 통해 방송신호를 수신한다.

The digital signal is terminated on Dec.31, 2012. But most of the analog cable subscribers are faced with the difficult reception of the digital because the government has defined the terrestrial broadcast as digital transition obligation operators. It is estimated that half analog of the total pay-TV subscriber that is approximately 10million households that are directly receiving terrestrial signal must hold the digital TV or DtoA convertor to transit digital. But cable system subscriber should buy Set-top box that are expensive and pay the expensive rates. The cast of analog cable subscribers has been classified as a group that can cause the most damage after digital switch. This study investigate the problem, and cause, solution of the analog cable subscribers that are placed in the blind spots of the digital switch.
