As intuitive hardware interfaces continue to be developed, it has become more important to recognize the posture of the user. An efficient alternative to adding expensive sensors is to implement computer vision systems. This paper proposes a method to recognize a user's postured in a live broadcast bi-directional participatory TV program. The proposed method first estimates the position of the user's hands by generation a facial color map for the user and a motion map. The posture is then recognized by computing the relative position of the face and the hands. This method exhibited 90% accuracy in an experiment to recognize three defined postures during the live broadcast bi-directional participatory TV program, even when the input images contained a complex background.

Recent commencement of digital broadcasting has enabled various TV programs through hundreds of channels. As a result, it becomes a time-consuming job for the TV audience to look up newspaper or TV magazines for the schedule of a specific TV program. To relieve this problem, digital broadcasting usually provides an EPG(Electronic Program Guide) for the audience. Currently. most EPG services are focusing on the visual delivery of information through a web site, digital TV or mobile devices. However, this approach could cause a serious restriction to some users including drivers or visually handicapped persons, who can't input keywords for the search. In order to solve this problem, in this paper, we propose a VoiceXML-based EPG retrieval system that enables even such special users to browse EPG. conveniently using a mobile phone. We implemented a prototype system and proved its effectiveness through experiments.

A conventional TV relay broadcast is a method of transmitting a program by means of a microwave, a leased wire, or a satellite. With the latest advances in LTE network, a relay approach using LTE mobile communications network has become increasingly competing with the traditional TV relay broadcast method. Since 2012, TV Chosun has been using the LTE network for marathon production, and channel A has also broadcast a marathon production broadcast using the LTE network. Therefore in this paper, we investigated the marathon relay method using LTE mobile communications network and compared with the traditional TV marathon relay method, and then suggested the optimum method for the marathon relay.

With the emergence of digital TV broadcasting, various TV channels are provided to a TV audience. But it is getting hard for the audience to find his or her preferred TV programs due to the huge number of TV channels. In order to mitigate the difficulty, channel navigation schemes have been proposed. The schemes predict preferred TV channel from viewer's previous watching histories, and provide the predicted channels when the viewer wants to change TV channel. As channel navigation schemes, there are Most Recently Selected (MRS) scheme providing the most recently watched channel, and Most Frequently Selected (MFS) scheme providing the most frequently selected channel. However, MFS and MRS scheme could be inappropriate to current TV system broadcasting various TV programs in a channel because they are based on the viewer's patterns of watching TV channels. Therefore, this paper proposes an efficient channel navigation scheme, Program Most Frequently Selected (PMFS), based on patterns of watching TV programs instead of TV channels. Simulation results show that the proposed scheme PMFS reduces the seek distance compared to the previous channel navigation schemes, MFS and MRS.

The purpose of this study was to investigate how much multi-cultural traits the multiculture-oriented TV programs would have and how they tended to represent it with what kinds of meaning structures. As an object of this study, the authors chose the Program of KBS-TV which had been discussed seriously to raise a multi-cultural issue as well as a sexuality issue of lady guests. They collected 70 weekly programs from Nov. 26 of 2006 to March 31, 2008, and finally selected and analyzed 5 weekly programs as main analytic data. They tried to analyze them with various semiotic research methods, especially, linguistic semiotic research methods and pictorial research methods. As results of this study, it was found that this Program was based on multiful-levels of meaning structure: that is, superficial level, representation level and in-depth level. The superficial level of this program presented various multi-cultural traits through many and various talks of lady guests. Its representation level indicated some patterns of discourses about issues and agendas of the talks among lady guests. The in-depth level was based on the sexuality of lady guests as well as the male-dominant ideology.

This research investigated television and video viewing of young children in early childhood all-day program settings and teachers' recognition of its effects on young children through the survey of 452 early childhood teachers. The results show that television and video viewing is used as a whole group activity during transition period and/or waiting time activity for children who come earlier in the morning and remain late until closing time. It means television and video viewing at early childhood settings is mainly used as a group baby sitter or pacifier. Daily viewing time is about 44.02 minutes and early childhood teachers show low recognition of their role in children's viewing habits. Young children's viewing patterns and time are differed by teachers' variables so that young children of beginning teachers at small size settings appear more viewing time. Teachers show more negative recognition of television and video viewing on young children when they are older and have higher educational level and longer education experiences. The results also show that the more teachers have positive recognition on television and video viewing, the more young children are exposed to television and video viewing in their classes.
