With the development of broadcasting technology from analogue to interactive digital, the number of TV channels and contents provided to audience is increasing in a rapid speed. In this multi-media and multi-channel world, it is difficult to adapt to the increase of TV channel numbers and their contents merely using remote controller to search channels. Due to this reason, EPG (Electronic Program Guide) has been one of the essential services providing convenience to audience. So EPG complying with European DVB-MHP specifications, which will be also our domestic standard, is proposed in this paper. In order to provide audiences with DiTV contents they preferred, we apply collaborative filtering algorithm to recommend contents according to preference value of audience group with similar preference. And we use JavaXlet application which is based on MHP to implement this EPG, while the result can be verified by OpenMHP emulator.

SBS has developed "Social DMB App" and now the service through Android market, where the viewers can produce and share their emotion related in program using twitter while watching real-time DMB broadcasting program at the same time. Previously, it is difficult to combine TV and social media because of the difference of family shared medium and individual service. But, DMB, individual mobile broadcast service, can offer new interest to the viewer by integrating social media service and broadcast. The service base was provided to the viewer where they can use original contents of broadcasters by constructing social circle and they are able to express and share their emotion through social DMB app. In this paper, introduce of development technical for social DMB app service include of configuration app servic, link of DMB broadcasting and facebook.

In designing a video-on-demand (VoD) system, one of the major challenges is how to reduce the viewer's waiting time maintaining a given bandwidth allocation and how to reduce the client's buffer requirements. To solve these problems, many VoD schemes were proposed. However, most VoD schemes require managing many segments of a video, frequency channel hopping, and using many channels at the same time. Therefore, to the complexity is a barrier to implementation. In this paper, we propose a fast staggered broadcasting scheme which has a simple structure and substantially improved VoD efficiency. The numerical results demonstrate that the viewer's waiting time of the fast staggered broadcasting scheme is close to the fast broadcasting scheme and the buffer requirements of this can be adapt for demanding rate by adjusting the short front part of a video sizes.

According to a statistical survey, despite the continuous improvement of the economic level, the participation rate of donations is decreasing. As a cause of this phenomenon, the problem of reliability of donation organizations is a big part. In order to increase viewers' intention to donate, this study developed a donation campaign linked data service that shows information that can increase the credibility of donation organizations and storytelling of donation recipients. Specifically, a user scenario of a data service that is properly operated in conjunction with a donation campaign that is broadcast shortly was defined, and a user interface was designed by reflecting the characteristics of the TV platform. In addition, a prototype based on the DVB-MHP standard was developed to analyze the effect of the data service utilization on viewers' intention to donate.

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.

This study on the exposed the viewers diversity as a basic cable television service. Diversity is the most basic goal of broadcasting policy has important implications. But still, such as cable and pay-media research on the viewing diversity has made a limited basis. SO much to offer for the cable offers viewers receive the number of channels available to compare the diversity of the field was verified. Price rises of analysis for the cable the more the number of channels offered to supply the channel has increased the diversity of the field. SO granted in accordance with the results of a market strategy, but for a variety of channels to be provided by a policy perspective, the price depending on the choice of a variety of audiences can be quite limited means. That is a wide range of viewers watching the channel had a right to be limited. These phenomena to improve the pay television service and the need to manage the Product channel diversity index was raised.

The purpose of this study is to analyze the effect of the humor on anchor credibility, attitude and to examine the moderating impact of news type. We showed two versions of the news broadcast: one with humor, the other without it to 222 university students and analyzed how the presence of humor affects on the anchor credibility, attitude and examined the moderating role of news type. The results demonstrate that the use of humor has a negative influence on anchor credibility, but doesn't affect anchor attitude. Regarding the moderating effect of news type, the group who watched soft news was not influenced by the presence of humor, but the group who watched hard news revealed that their anchor attitude became dramatically better with the use of humor.

This study is aimed at investigating the factors that influence the profits of Internet personal broadcasting to improve unstable benefit structure. 50 viewers of game broadcasting that includes most of internet personal broadcasting's personalities are surveyed, who are watching the broadcasting everyday more than an hour and backing to a broadcast conductor. For investigating Benefit Structure Analysis of Internet Personal Broadcasting, independent variables are composed of Social viewing experience, Parasocial relationship, and Information seeking motive and mediator is composed of viewing satisfaction that influences dependent variable, purchase intention. As a result the study founds that only two independent variables(Parasocial relationship, Information seeking motive) affect to mediator and viewing satisfaction affected to dependent variable.
