In this paper, we study on making a use of value-added services using DTV closed caption data. Note that Closed-Captioning service helps to bridge "digital divide" through extending broadcasting accessibility of a neglected class such as hearing-impaired person and foreigner. In Korea, DTV Closed Captioning standard was developed in June 2007, and Closed Captioning service should be provided by an enforcing law in all broadcasting services in April 2008. Here, we describe the method of extracting a caption data from MPEG-2 Transport Stream of ATSC-based digital TV signal and generating a caption file using the extracted caption data and time information. In addition, we present the segmentation method of broadcasting content using caption file. Experimental results show that implemented S/W tool provides the feasibility of the proposed methods and the usability of closed caption for a variety of data application service.

In the rapid digital transformation era, kiosks have become a common element in daily life. However, their widespread deployment has introduced new challenges for socially marginalized groups, including individuals with disabilities and the elderly. This study aims to evaluate the usability of kiosks for individuals with low vision and propose improvement strategies. The study was conducted with eight low-vision university students from A University in Gyeongsangbuk-do and four non-disabled university students from Daegu. Usability was assessed through experiments involving a self-service certificate issuance kiosk and a fast-food restaurant kiosk, using Jakob Nielsen's five usability evaluation criteria: learnability, efficiency, memorability, error prevention, and satisfaction. The results revealed that individuals with low vision faced significant difficulties with small text size, low contrast, no physical buttons, and lack of screen zoom functionality. To address these issues, the study recommends enhancements such as increasing text size and contrast, incorporating physical buttons, adding zoom functionality, ensuring consistent UI design, and providing auditory feedback. This study provides foundational data for enhancing information accessibility for individuals with low vision. It offers critical insights into kiosk design and policy recommendations, thereby contributing to the mitigation of the digital divide.

The purpose of this study was to examine the relationship between the access level of digital information service and life satisfaction level of the middle and high-aged people and to analyze the Sequential Mediation Effects on online social engagement and online network activities. To this end, we analyzed the effects of multiple mediations on 1,491 seniors who responded to the 2018 digital information gap survey. The results of the study are as follows: First, this study confirmed that there is a statistically significant relationship between the access levels of digital information service and the life satisfaction. Second, the results showed that impact of digital information access level on life satisfaction among high-aged people was higher when they were engaged in both online social activities and online networking, rather than only involved in online social activities. Overall, this study comprehensively examined the relationship among the level of digital information access, life satisfaction, online social engagement, and online networking, which is meaningful in that it can be used as data for reconsideration of the digital information services and life satisfaction of the high-aged people.

Recently, the comparative gap of technology and product has been decreased in the global market, and the globalization has been extended rapidly. Industries try to get de facto standard as the global standard. De facto standard has become a standard not because it has been approved by a standards organization but because it is widely used and recognized by the industry as being standard. Advanced countries already have their own organizations under the government, and they cooperate tightly with companies. As a result, we also try to have the organization and build the good relationship between companies and the government to get de facto standard in the global market.

실감형 콘텐츠는 정부가 발표한 미래성장동력에도 포함될 정도로 정부와 산업계의 뜨거운 관심을 받고 있는 분야입니다. 사실 실감형 콘텐츠란 하나의 기술 분야를 말한다기 보다는 인간의 감각 기관과 인지 능력을 자극하여 실제와 유사한 경험 및 감성을 느낄 수 있게 해주는 유형의 콘텐츠를 통칭하는 것입니다. 그래서 지금까지 경험한 평면적인 디지털 콘텐츠나 3D 콘텐츠보다 더 몰입감 있고, 신기하고, 새롭고, 재미있고, 기대되는 콘텐츠라고 할 수 있지요. 2000년대 들어 우리는 이미 공상과학 영화를 통해 실감형 콘텐츠의 모습이 어떤 것인지 간접적으로 경험해 왔고, 그러한 기술들이 최근에 콘텐츠의 모습으로 완성되면서 실제적인 경험을 하고 있습니다. 하지만 더 흥분되는 사실은 지금 우리가 경험하는 것은 아주 일부분의 맛보기일 뿐, 앞으로 소개될 콘텐츠들이 제공할 새로운 경험은 더 압권이 되겠지요. 최근 정부와 산학연의 실감형 콘텐츠 기술 개발은 많은 제약과 어려움에도 불구하고 매우 적극적으로 추진되고 있습니다. 국제 표준화 기구에서 치열하게 추진되는 표준 개발에도 국내 전문가들이 적극적으로 대응하고 있습니다. 이 특집에서는 실감형 콘텐츠에 대한 개념과 트렌드를 전문가 인터뷰를 통해 들어 보고, 실감형 콘텐츠를 구성하는 여러 가지 기술 중에서도 소비자들의 기대와 눈높이를 맞춰줄만 한 새롭고 기대를 모으는 것들을 살펴보고자 합니다. 앞으로 우리는 입체 공간에서 1인칭 시점으로 얼마나 실감나게 콘텐츠 속으로 빨려들어 갈 수 있을까요? 지금까지 경험한 콘텐츠 조작은 얼마나 새로워질까요? 내가 필요할 때 딱 맞는 콘텐츠를 바로 이용할 수는 있을까요? 우리가 이렇게 새로운 것으로 즐거울 때 혹시 소외되는 사람들이 있지는 않을까요? 분명 있겠지요. 그렇다면 어떻게 우리는 정보격차를 극복할 수 있을까요? 이러한 물음에 대한 전문가들의 의견을 들어보시기 바랍니다.

For large multihop networks, large time synchronization (TS) errors can accumulate with conventional methods, such as TPSN, RBS, and FTSP, since they need a large number of hops to cover the network. In this paper, a method combining Concurrent Cooperative Transmission (CCT) and Semi- Cooperative Spectrum Fusion (SCSF) is proposed to reduce the number of hops to cover the large network. In CCT, cooperating nodes transmit the same digitally encoded message in orthogonal channels simultaneously, so receivers can benefit from array and diversity gains. SCSF is an analog cooperative transmission method where different cooperators transmit correlated information simultaneously. The two methods are combined to create a new distributed method of network TS, called the Cooperative Analog and Digital (CANDI) TS protocol, which promises significantly lower network TS errors in multi-hop networks. CANDI and TPSN are compared in simulation for a line network.
