As a future key industry, digital signage is being noticed that provides various type of contents and message through a digital display. In particular, korean digital signage industry gets a favorable evaluation for the high level of digital display industry and wired and wireless networking infrastructure. This paper discusses on not only the current status of digital signage in terms of the overall development and standardization, but the very recent technologies such as the ultra-high definition video and human perception that can be applied for future digital signage. Then, this paper concludes by deriving the problems with the current digital signage industry and presenting solutions for future vitalizations of digital signage.

In the airport, digital signage is used to provide the flight-related information for the passengers. Because the current digital signage is based on wired networking or storage medium, its use is limited in terms of the location and the usage of the digital signage. In order to overcome these limitation, we present a WiBro-based digital signage for the wireless broadband networking and the mobility of the digital signage. We perform comparative experiments with the WiBro-based digital signage and WLAN-based digital signage under various locations, datarate, advertisement contents. The experimental results showed that the WiBro-based digital signage is preferred when the mobility is required, while the WLAN-based digital signage has advantage in datarate.

Digital signage in airport is used to provide the flight and airport information to the airport passenger. However, the current digital signage displays one type of contents to all of the airport customers without considering the type of the customer. Thus, the digital signage suffer from the inefficiency problem resulting in lower customer satisfaction. This problem can be solved if we adopt a smart digital signage which can recognize the type of the customer and provide the tailored contents. In this study, we report a smart digital signage using age recognition. Our smart digital signage can recognize the age of the customer in real-time, and provide the tailored contents to the customer. The smart digital signage can improve the airport customer satisfaction and the airport work efficiency by providing the information that is needed by the airport customers.

This study examined how the memory effect and the brand attitude effect differ according to the interaction (high / low) and the involvement (high / low) of digital signage. The two-way MANOVA analysis using SPSS 18 was used for the empirical analysis. The results of this study are as follows: First, GRM is recalled if the level of interactivity and inffence of digital signage is low, but if both conditions are high, ARM recalls. Second, if the interaction of digital signage is low and the level of engagement is high, a lot of memory information is formed that forms the overall attitude of the product. In addition, even though the interaction level is high and the engagement is low, the attitude cognitive response through the overall evaluation is formed rather than the attribute information. Third, brand attitude was positive when interactivity level was high and engagement level was high.

본 논문에서는 상황 적응적 디지털 사이니지 시스템을 다룬다. 디지털 사이니지 디스플레이는 정보 및 광고 제공에 효과적인 매체이다. 시청자, 장소, 날씨와 같은 환경적 상황에 콘텐트를 적응시킨다면 디지털 사이니지는 더욱 효과적일 수 있다. 본 논문에서 제안하는 상황 적응적 디지털 사이니지 시스템은 다양한 환경 상황에 적응하여 콘텐트를 제공한다. 상황을 인지하기 위해 카메라, 온도계 등 다양한 센서들이 사용된다. 이 시스템에서는 다수의 상황들이 모델링되며, 해당 상황들에 대한 콘텐트가 체계적으로 저장되고 제공된다.

Digital signage provides flight and airport information to the airport visitors and passengers. However, the digital signage has efficiency problem by displaying one type of advertisement to every customers regardless of their personality. We may solvel the inefficiency problem by using a smart digital signage which can recognize the characteristics of the customer We presents a smart digital signage with sex recognition function. The smart digital signage can recognize the sex of the customer to display the custom-made advertisement in realtime so that we can increase the satisfaction level of the airport passengers and visitors.

In this paper, context-aware technologies using a Kinect sensor for a digital signage which is increasingly growing as the 4th screen media is presented. Generalized context-aware functions for a digital signage were studied and a context-aware digital signage platform was developed. It can support a natural user interface for controlling a digital signage and actively provide contents adapted to its context. As a basic context, user's gesture and voice, the number of users, sound direction were considered. In the future, the advanced functions such as age, gender will be studied. The implemented platform could be a good reference model when developing a general context-aware digital signage.

현재 현장에 설치되어 운용되고 있는 대부분의 디지털사이니지는 독자적인 설계와 구현으로 개발되었기 때문에 다른 시스템과 연동이나 상호 운용하기에는 많은 어려움이 있다. 향후 웹 기반의 개방형 디지털사이니지가 주류를 이룰 것으로 예상됨에 따라, 다양한 서비스나 단말장치와 연동할 수 있는 상호 운용성을 갖춘 솔루션을 위한 기술 표준화 작업이 활발하게 진행될 것으로 예상된다. 최근 몇 년 전부터 ITU-T, POPAI, W3C 등을 중심으로 디지털사이니지 기술 표준화가 진행되고 있으며, 국내에서도 디지털사이니지 산업이 성장하면서 표준화에 대한 관심이 고조되고 있다. 이에 본고에서는 ITU-T, POPAI, W3C, 일본 등 해외에서 행해지고 있는 최근의 표준 활동과 TTA를 중심으로 한 국내의 표준 활동을 소개한다.
