Due to the development of the digital technology, the digital broadcasting is changing to a multi-entertainment platform that can operate data (broadcasting) services (such as games, weather information, and stock trading services) as well as traditional broadcasting contents. Most of the data services, however, failed to get satisfactory results because of the inconvenience in operating the services using a TV remote controller and the failure of gaining the viewer's interests in the competition with the broadcasting contents. The paper introduces a survey on the viewer's modality of using a data service and, based on the survey result, proposes a design guideline that makes a data service minimally interrupt a viewer watching a broadcasting content.

Since the inception of Internet Protocol TV's real-time service on January, 2009, technological challenges and lack of content diversity of IPTV have been cited as problem areas. While past researches focused on IPTV's technological, industrial and policy facets, this research surveyed the viewers' viewing and usage patterns, and the level of service satisfaction among actual audiences of MegaTV, SKBroadband, and LGTV since January. The results show that subscription fee and content types were the two dominant determinants in audience's choice of a particular IPTV company. The high users of IPTV were on average aged between 30-39, and women tended to be heavier users than men. The surveyed audience also regarded IPTV to be more similar to the Internet than any other medium such as Cable TV and Satellite TV. IPTV audience cited 'lifestyle service' and 'additional service' offerings to be highly relevant to their usage and satisfaction; interactive service and educational service also showed high correlation to usage and satisfaction. The most watched contents on IPTV were domestic TV series, followed by foreign movies and variety shows. 'Fees for additional features,' 'lack of real-time terrestrial TV service', and 'lack of content variety' were the major areas of concern for IPTV viewers. They answered that the monthly fee was the most important factor in the selection of IPTV. Use of pay-per-view contents and add-on interactive service fees were also seen as problematic. With regards to future usage, the IPTV audience revealed that they were very sensitive and reluctant to pay for additional services. While existing researches concentrated on IPTV's technological problems and lack of content diversity, this study illuminated the more pragmatical side of the viewers, namely, the importance of price in audience's selection of an IPTV service provider. From these results, it is recommended that, before doing anything else, the service providers try to meet the audience's expected price points in order to garner the full potential of IPTV and the attendant mass audience.

Due to the development of digital appliance, role of TV causes both-way by introducing IPTV, and SNS service causes big change of watching environment and residence environment. There are good conditions on the role of integrated control because it is arranged in the living room which secures movement most effectively and because family members can easily use, and the degree of use is high. Therefore, we infer user's needs by analyzing user scenario and current role of TV in home network environment. Primarily, we collect surveys of development scenario and technology which companies suggest TV applied by home network service, and secondly, we comparatively study scenario which the companies mentioned above suggest through observing user scenario, and study the role of IPTV in the future through actual scenario-based experiment by ethnography. After analyzing user scenario through case study and experiment, there are integrated device studies mainly in company study because it can be made up inside home, security and entertainment. On the other hand, there are patterns of user behavior by scenario experiment mainly in auto-tainment, security, and it showed that it is insufficient for interaction between TV and home media peripheral. Through this paper, we analyze context of home user, and based on this, we could suggest effective use of service development. Also after analyzing user form, we could know it also should be considered of ratio between activity inside home and activity outside home.
