현재 모든 IT산업의 중요 키워드는 융합이다. 그중에서도 가장 두드러진 것은 방송과 통신의 융합이다. 하지만, 사업자간의 이해득실이 얽혀있는 상황에서 방통융합은 결코 쉽지 않을 전망이다. 주요원인은 통신망을 통해 방송을 서비스하게되면 방송산업의 구조조정이 본격화될 것이 틀림없기 때문이다. 특히 우리나라와 같이 거대통신회사가 있는 경우에는 더욱더 방송산업의 타격이 클 것으로 예상된다. 이에 본 논문에서는 방송망을 통해 통신서비스를 지원하는 방통융합 서비스에 관한 연구이다.

본 논문에서는 지상파 UHF 휴대용 슬리브 안테나를 설계 제작하였다. 이 안테나는 차량 네비게이션장치에 들어가는 지상파 UHF TV 수신을 위한 안테나이다. 기존 모노폴 형태가 갖는 단점을 제거하고 성능 향상을 위해 세트 external 안테나로, 필요시에 목걸이형으로 부착이 가능한 구조를 가지고 있다. 동축선을 이용하여 슬리브 다이폴 안테나로 설계함으로써 안테나 입장에서 볼 때 접지가 부족한 문제를 해결하였다. 제작 측정한 결과 UHF 대역에서 VSWR 2:1 이하의 특성을 만족하였다.

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.

In the field of video design, motion graphics tends to be realized to deliver a certain message properly incorporating basic motion graphics components such as space, form of expression, and time, and has continued to be used as a powerful communication tool. Many cases proved that title sequences were produced as a result of combination of a variety of quick images and effects with appropriately chosen sounds to meet the demands of audience. This study indicated that motion graphics began to be widely used as a more powerful video communication tool for title sequences and also applied for M-NET, DMB, CABLE TV, IPTV, and others.

Object: To analyze the effect of a media-campaign for "walking exercise participation improvement", which impacted walking-related awareness and behavior change of residents in Seoul. Method: This study used three campaign media including printing information, walking exercise indication board and a public advertisement of cable TV to lead a walking-related awareness change and practice frequency(number of days per week walking) and time(minutes per day walking) of walking exercise. To evaluate the exposure and message-recall levels of a campaign and effects of awareness change and walking practice, this study used a questionnaire survey(N=377). Result: 1) Group of exposure to campaign more participate and had the higher frequency(p=.015) and time(p=.023) in walking exercise and in comparison with group of nonexposure. 2) Group of changed awareness to campaign more participate and had the higher frequency and time in walking exercise and in comparison with group of no changed perception(p <.05). 3) Level of message recall of ${\ulcorner}$printing information${\lrcorner}$ was associated with number of days per week walking, and level of message recall of ${\ulcorner}$public advertisement of cable TV${\lrcorner}$ was associated with minutes per day walking at a statistically significant level(p <.05). Conclusion: These results suggest that media campaign can enhance the success of community-based efforts to promote awareness change and walking practice.

The purposes of this study are to determine dimension of apparel expectations. performances and service quality of home shopping and thereby, to analyze effect of apparel commodities dimension (expectations, performances, disconfirmation and satisfaction) and service dimension (service quality and satisfaction) on repurchase intention. The subject were 351 women in the age of twenty to sixty years old who live in Seoul and the suburban of Seoul. The results of this study can be summarized as follows : 1. It was found that home shopping consumers' expectation and performance with apparel commodities were classified 3 factors. On the other hand, the dimensions of service quality were found to have such 3 factors as convenience reliability, personal factor, and apparel one. 2. More frequent users of home shopping scored more on average than less frequent users in terms of service quality, service satisfaction and intention of repurchase. On the other hand, the cable TV users scored more on average than catalogue users In terms of service quality and intention of repurchase. 3. It was found that consumers' intention of repurchase of home shopping were affected by such variables as discofirmation and satisfaction with apparel commodities, service quality and service satisfaction. While less frequent users were affected by disconfirmation and service quality, more frequent users were affected by such variables as apparel commodities satisfaction, service quality and service satisfaction. Meanwhile, both cable TV and catalogue users were found to be affected by service quality and service satisfaction.

A new analysis method of lumped-element directional coupler for CATV was proposed, where the even-and odd-mode theory for a symmetrical coupled-line directional coupler was applied to a transformer-type directional coupler. In addition, the tap-offs were analyzed by the proposed theory, which are widely used in CATV (Cable Television) systems. By comparing the calculated results for S-parameters results to the measured ones using only the even-and odd-mode reflection coefficients, the validity of the proposed analysis method was confirmed. Then, it was clearly shown that the tap-off has very wide bandwidth from 5 MHz to 4,000 MHz by adopting the proposed theory.

In the TV broadcasting, movie production and business the transportation of video between creators (programmers, studios) and distributors (broadcast and cable networks, cable and satellites companies) is still a mix of File Transfer Protocol (FTP), physical delivery, and expensive multicast satellite. Cloud-based file sync-and-share providers like Dropbox and box are playing an increasing role, but the industry's unique demands for speed and multicasting have fueled the growth of IP Video transport. This paper gives a solid grasp of the major elements of IP video technology, including content preparation, system architecture alternatives and network performance management.

In order to respond to the ever-changing media environments in the era of smart and mobile technology, KBS has introduced and partially applied PIE-TV and PIE-nonTV modes that monitor the average number of viewers among the national population group by means of the sample household extraction method which is a traditional way of rating investigation. This study analyzes the correlation between the number of viewers of premiere, re-air broadcasting, and MPP channel programs and the number of OTT-based VOD viewers in reference to the data extracted from PIE-TV survey results. KBS conducted a survey for 3 months between June and August 2017 to measure the PIE-TV Index, based on which the above-mentioned correlation was analyzed with programs classified to entertainment, drama, and cultural programs. For data analysis, SPSS (Ver. 18.0 for Window, SPSS Inc, Chicago, IL, USA) was utilized. It was assumed that when p<0.05 in the confidence interval of 95%, statistically significance would be secured. Among the 30 subjects in the simple correlation analysis, the parameter was determined by the Person correlation coefficient and the non-parameter by the Spearman correlation coefficient. Analysis results are as below: (1) As the number of viewers of premier entertainment, drama, and cultural programs was larger, the number of VOD viewers was larger accordingly. (2) As for entertainment and drama programs, as the number of re-air broadcasting viewers was larger, the number of VOD viewers decreased accordingly. (2) As for entertainment and drama programs, as the number of MPP viewers was larger, the number of VOD viewers decreased accordingly. It is expected that this statistical data can be utilized for strategic planning of MPP channel lineups including terrestrial TV broadcasting, cable TV, etc.
