Smart TV is a television set with internet capabilities, computing ability, and broadcasting service that increases user interactions. Usability has been regarded as one of the most important criteria for measuring and evaluating smart TV. To evaluate smart TV from the perspective of usability, we first need to develop a measurement model by determining the major factors affecting usability, which become a measurement the evaluation criteria of the model. The objective of this paper is to suggest an AHP(Analytic Hierarchy Process) model for measuring usability of smart TV. Factors affecting usability are described from the prior research. We show how the judgment data is acquired and the usability score is computed by an numerical example.

Domestic kids TV animation industry is settled well in domestic animation industry by adding both entertainment value and educational value. Specially, the character that represents various rolls in the kids TV animation is the core visual element. This study is the analysis for character's subject matter of expression. For this, I established the tool which could classify character's subject matter of expression, and apply the tool to the character which were selected in broadcasting kids TV animations on EBS. Through this procedure, I analyzed character's subject matter of expression with the distribution chart as the final step. In addition, I hope the result of this study could intend to provide the index of the character creation in the kids TV animation and also informed the current situation about the character's subject matter of expression in the kids TV animation.

Advances of digital device technology such as digital cameras, smart phones and tablets, provide convenience way for people to take pictures during his/her life. Photo data is being spread rapidly throughout the social network, causing the excessive amount of data available on the internet. Photo retrieval is categorized into three types, which are: keyword-based search, example-based search, visualize query-based search. The commonly used multimedia search methods which are implemented on Smart TV are adapting the previous methods that were optimized for PC environment. That causes some features of the method becoming irrelevant to be implemented on Smart TV. This paper proposes a novel Visual Query-based Photo Retrieval Method in Smart TV Environment using a motion sensing input device known as Kinect Sensor. We detected hand gestures using kinect sensor and used the information to mimic the control function of a mouse. The average precision and recall of the proposed system are 81% and 80%, respectively, with threshold value was set to 0.7.

디지털 TV 방송은 미국, 영국, 일본 등 주요 선진국에서 이미 90년대 중반부터 실용화되고 있으며 향후 T커머스와 데이터 방송 등 다양한 인터랙티브 서비스 등을 제공할 수 있도록 발전하고 있다. 우리나라에서도 현재 지상파 시험방송을 실시하고 있으며 2002년 월드컵을 전후하여 본격적인 방송이 가능하도록 서두르고 있다.(중략)

삼성전자는 LCD 방식에 이은 3세대 프로젝션 모델로 평가받는 DMD (Digital Micromirror Device) 기술을 채용한 43‘’, 50‘’, 61‘’ DLP (Digital Light Processing) 프로젝션 TV를 개발 시판하고 있다. DMD 기술이란 921,600개의 미세한 거울들이 신호에 따라 반사각도를 조절하며 이미지를 구현하는 기술이다. 삼판식 프로젝션 시스템의 단점을 개선, 경박단소와 저가격화를 위하여 단판식을 이용하는 DLP 프로젝션 TV 의 경우 Red, Green, Blue 로 이뤄진 칼라휠을 회전시킴으로서 DMD 위에 연속적으로 삼색의 영상을 재생하여 색을 분리 합성한다.

우리네 일상에서 옷을 입고 밥을 먹고 잠을 자는 행위만큼이나 당연하고 자연스러운 일로 TV 시청을 든다면 대부분 수긍할 것이다. 물론 요즘 일부에서는 TV안보기 운동 등을 벌이며 TV의 존재감을 애서 무시하려고 하지만 , 그만큼 TV는 우리 생활 깊숙이 들어와 있다고 할 수 있다. 최근 들어 TV관련 이슈가 많이 나오고 있다 . 휴대가 간편한 DMB단말기에서부터 인터넷 망을 이용해 즐기는 IPTV에 이르기까지 이제 TV는 새로운 모습으로 시청자들에게 다가서고 있다.

It has passed the era of Full High Definition Television (FHD) and ended the era of Ultra High Definition Television (UHD). We will talk about the problems caused by the difference in the number of pixels in the TVs and introduce a method to improve them. This method is a method of performing an interpolation method suitable for a given image with Weighted Essential Non-Oscillation (WENO). Thus, it is possible to reduce the distortion of the image and to ensure a better image quality. Therefore, if we use the WENO methodology, when we watch old video material on UHD TV, we can enjoy high definition of UHD TV without changing the number of pixels.
