In this paper, we are interested in tennis games and the best of all matches that is fair to most of all participants. We introduce a loss function. And using our introduced loss function and round robin method, we get a best match that obtains the minimal loss according to the number of participants.

It has become five years since comprehensive programming licenses were rendered in Korea. Allocating a lion's share of their air time on live news and news commentaries, those channels have established a unique live production system or a broadcasting system which is heavily live production-oriented, to be exact. The live commentaries are filled with a mixture of news flashes, conventional news commentaries, and debates. Those channels get their news and commentary programs made through subsidiaries' where production directors and studio staffs belong. They, being very sensitive about viewer rating, tend to be aggressive about reruns of highly rated programs and they do not even seem to care when the regular programs actually went out. This kind of reckless strategy to pursue a higher viewer rating could limit not only new programming attempts but also exposure diversity.

In this paper, we are interested in tennis games and the best of all matches that is fair to most of all participants. Especially when players are ordered in accordance with their playing ability, we are interested in finding the best of all matches that is even with each other's playing pair. We propose a loss function And using our proposed loss function, we get a best match that obtains the minimal loss according to the number of games for given participants.

최근 방송의 디지털화에 따라 수많은 채널의 수용이 가능하게 되어, 현재와 같이 신문의 방송편성표를 보고 사용자가 원하는 프로그램의 시작 시간을 알아내는 것은 힘들어 졌다. 디지털방송에서는 신문 방송 편성표와 같은 기능을 하는 방송 프로그램에 대한 정보를 보여주는 EPG(Electronic Program Guide)를 제공하고 있다. 현재 서비스되고 있는 EPG를 보면, 프로그램의 시작 시간을 GUI로 사용자가 쉽게 알아 볼 수 있어 하고 있어 신문 편성표나 인터넷으로 제공되는 각 방송국의 편성표와 달리 TV 화면에서 프로그램 정보를 검색할 수 있어 편리해졌다. 그러나 이 EPG에서 제공되는 시간은 매우 부정확하기 때문에 시청자가 불편을 느낄 수 있다. 본 논문에서는 방송의 시작 시간을 정확히 알아내어 EPG를 정확히 갱신하는데 목적이 있다. 이를 위해 방송의 시작부분을 미리 저장한 후, 시작 부분을 Visual Rhythm을 이용해 shot들을 추출하여 데이터베이스를 구성하고, 이와 같은 방식으로 방송 스트림의 shot들도 추출하여 데이터베이스와의 Pattern Matching을 통해 보다 정확한 방송시간으로 EPG를 갱신하고자 한다.

The purpose of this study is to analyze the change of programming strategies of chinese broadcasting as competitions intensify in the niche dimension. Specifically, the niche breadth which indicates the diversity of program genre and way of program production, the niche overlap which indicates the degree of competition among the channels, are investigated. The results show, as the competition has intensified, three chinese television pursued different programming strategies; CCTV1 maintained programming strategy without big change, while Hunan and Gangso pursued change of programming strategy. However the change of programming strategies of Hunan and Gangso showed different direction; Hunan has tended narrows niche breadth of program genre and the way of progrm production, while Gangso broadens niche breadth. In overall, Chinese broadcastings have found the way of co-exist pursuing different programming strategy. And the programming strategy of Gangso satellite broadcasting which broadens niche breadth has showed better performance in rating and advertising revenue.

This paper investigates audience perception on news content through comparison analysis on Comprehensive Programming Channels, TV chosun, JTBC, Channel A, and Terrestrial Broadcasting 'KBS'. How sensationalism created by video news affect audiences' credibility on news and media. The results shows that Comprehensive programming channels are assessed more sensational than terrestrial broadcasters by audience. Additionally, Comprehensive programming channels are assessed to get a lower credibility than terrestrial broadcasters by audience in the analysis of news and media credibility, comprehensive programming channels and terrestrial broadcasters. As a result, comprehensive programming channels showed lower news credibility and media credibility compared to that of the terrestrial broadcasters. This means that comprehensive programming channels must do the best not only recovering credibility from audiences but also constructing position as national broadcasting media.

DMB(Digital Multimedia Broadcasting)란 CD수준의 음질과 데이터 또는 영상 서비스 등이 가능하고 우수한 고정 및 이동 수신 품질을 제공하는 디지털 방식의 멀티미디어 방송이다. DMB는 서비스 방식에 따라 위성DMB와 지상파DMB로 나누어지며, 영상 및 음성 서비스에 데이터 신호를 동기화 시켜 데이터 서비스 또한 가능하다. 지상파DMB 데이터 서비스중 EPG(Electronic Program Guide) 서비스는 시청자가 현재 시청 중인 채널의 프로그램 편성 정보를 사용자에게 정의한다. 그러나 DMB 사업자 간의 이해관계 등으로 인해 시청자가 타 채널 편성정보를 확인하기 위해선 채널을 변경(Tunning)해야 하는 불편함이 있다. 이를 해결하기 위해 본 논문에서는 BWS(Broadcast Web Site) 표준과 리턴패스(Return Path)를 이용하여 지상파DMB의 EPG에서 확장된 개념인 XPG(eXtended Program Guide)를 제안하고 구현하였다. 이를 위해 2장에서 지상파 DMB의 각종 데이터서비스 표준 및 리턴패스(Return Path)를 분석하였으며, 3장에선 XPG 서비스를 제공하기 위한 XPG 서비스 시스템을 설계하고, 이를 위한 XPG 애플리케이션을 설계 및 구현하고 그 결과를 나타내었다.

The purposes of this study are to see a manufacturing process on knit by comparison, and to present whole garment knitting machine different from the traditional method of the production by using the whole garment system. The characteristics of each stage were examined through SDS-one, Shimaseiki Design CAD System and the whole garment knitting machine. The whole garment knitting machine as a method of composing a suit of knitting product is a way of making creative knitting fashion, which also can be used as a basic material for the further study on the whole garment knitting machine. Eventually, it is expected that this machine can satisfy the knit wearers' various needs by showing more useful method to knit designers.

With the activation of OTT and VOD services, the viewing behavior is rapidly changing, but the programming regulation has not escaped the ratio regulation in the same way as in the past. Therefore, this paper aims to examine the policy validity of the current organization ratio regulation and to suggest improvement directions based on this. To this end, the policy objectives and background at the time of the introduction of the domestic organization ratio regulation were considered and compared with the current status of the broadcasting market. As a result, this study found that it is difficult to apply the logical framework of asymmetric regulation at the time of the formation ratio regulation into the current status of broadcasting market, the existing framework was established and hold in the mutual relationship of various stake holders formed based on the asymmetric regulation. It was pointed out that the typical pattern of path dependency repeating only fine adjustment of ratio was shown. Based on this, this study suggests that it needs to be divided into the regulation by the public interest and the regulation by the industrial purpose according to the purpose of regulation, and it is necessary to be limited to the direct regulation corresponding to the public interest of the viewer. Also this study proposes that it is necessary to separate the regulation from promotion policies as well as to resolute asymmetric regulation in broadcasting policies.

The dual-stream based stereoscopic 3D broadcasting standard was developed in 2011. EBS broadcasted 3DTV experimental service according to this standard in April 2012. Dual-stream based 3DTV broadcasting is service-compatible and backward-compatible, so viewers who have legacy 2D HDTV can watch the broadcasting content as 2D. And 3DTV viewers can select watching 2D or 3D. Since 3D content production is not usual yet for terrestrial broadcasters, only some particular programs in specific periods will be broadcasted as 3D at the initiatory stage. For it, stable viewing condition is strongly required for both 2D viewers and 3D viewers. This paper suggests broadcasting transmission system structure and effective switching scheme for stable 2D and 3D viewing conditions in the case of dual-stream based terrestrial 3DTV broadcasting.
