1990년대 말 본격화된 인터넷 서비스는 일반 개인들의 라이프스타일은 물론 정치, 경제, 사회, 문화적 측면에서 많은 변화를 야기시켰을 뿐만 아니라 텔레비전의 출현만큼이나 우리 생활양식을 크게 변화시켜 왔다. 나아가 통신망의 광대역화 및 방송의 디지털화에 따라 One phone, VoIP, WiBro, HSDPA, DMB, IPTV 등 유. 무선 통합, 음성. 데이터 통합 및 통신. 방송 융합이 발현되는 신규 서비스들이 속속 선보이면서 서비스, 사업자, 단말기 등이 융합되는 컨버전스 패러다임이 본격화되고 있는 양상이다. 이중 인터넷과 TV가 만나는 IPTV는 통신과 방송이라는 이종산업간의 대표적 융합서비스로서 VoIP, 초고속인터넷, TV 서비스를 동시에 제공하려는 통신사업자들의 TPS 사업전략의 일환으로 현재 전세계 280여 개 이상의 사업자에 의해 추진되고 있다. 이에최근 급부상하고 있는 IPTV 서비스에 관한 개념, 발전과정, 기술 배경, 국내. 외 사업자 추진 현황 및 향후 시장전망을 살펴봄으로써 IPTV 서비스의 발전가능성을 가늠해보고자 한다.

In response to the challenges posed by a super-aged society, local authorities are conducting educational programs on smartphone usage tailored for the elderly. However, obstacles such as the limitations of one-to-many education and suboptimal learning outcomes for the elderly have hindered the efficacy of smartphone education. This study suggests an educational service intended for direct application in offline settings, considering the identified problems. Through the utilization of generative AI, the proposed app identifies specific challenges encountered by users during actual smartphone use, offering personalized exercises to facilitate customized and repetitive learning experiences for individual users. When integrated with existing local government education initiatives, this app is anticipated to enhance the efficiency of smartphone education by providing personalized, one-on-one training that is efficient in terms of time and content.

BcN provides a wide variety of high-quality multimedia services such as broadcasting and communication convergence services. But the quality degeneration is observed in BcN when we use broadcasting and communication convergence service via more than one network of different internet service providers. In this paper, a QoS management system which is able to measure and maintain objectively the quality-related information in overall networks is proposed. The proposed QoS management system is tested on the pilot networks of BcN consortiums by measuring the quality of voice and video experienced by the actual users of the commercial video phone services. The result of the experiment shows that it is possible to figure out service qualify between a user and a service provider by analyzing the information from agents. The per-service traffic information collected by probes is proved to be useful to pinpoint the party responsible for the loss of the service qualify in case of the services including different service providers. As the result of the experiment, it is shown that the proposed QoS management system would play a key role of resolving the quality dispute, which is one of the important issues of QoS-guaranteed BcN.

The study aims to explore the factors that affect the value perception, satisfaction, and frequency of smart phone taxi applications in Shanghai, China, and commuters. According to a survey conducted on the actual use of taxi application, the majority of the customers responded that they have been using taxi apps for more than one or two years, and the results showed that they use taxi apps once or twice a week. It also showed that the actual use of taxi apps varies depending on their age and academic background. Among the value attributes of smart phone taxi applications, the respondents perceived ease of use as the highest at 4.41 points out of 5 point scale, while the risk perception was the lowest at 3.34 points. Finally, when social demographic characteristics and the nature of taxi app use were controlled, the value perception variables had a significant influence on taxi application satisfaction. The higher the perception of service quality, usefulness, and system usability, the higher the satisfaction levels were. In particular, the impact of perceived usefulness and system usability perception was high.

While lots of new mobile applications are being developed, applications that provide positional information by using LBS (Location Based Service) have become popular. For instance, smart phones are able to find my location and a destination easily by using GPS, which installed in the instrument, and run the program. However, these existing positional information applications can find the location of only one user at a time. These programs are not able to find out accurate directions from current location to the destination. This paper suggests a case of system development which solved some of the problems in the implementation of existing applications using LBS. The suggested system to solve these issues, having multiple users to share positional information and showing directions, run by AR (Argument Reality). In daily use, this application would be very efficient for location people in the vicinity.

An advancement and wide use of portable multimedia devices make it easy to spread digital sound source, enabling users to use portable multimedia devices and search and enjoy digital sound sources and related contents. In opposition the off-line musical service market with CD stagnates gradually and in the crisis where the off-line musical service market vanishes away. In this paper, we propose the mobile music album information retrieval system which combines the barcode and a cellular phone musical service. To get digital sound sources and related information from music albums, the proposed retrieval system uses one-dimensional barcodes attached to music albums and obtains information on related albums from the sound source servers. Also, to reflect user preferences in search results, the system uses search frequency by music album, and searches albums in music genres selected by users in the order of the recent preference. The proposed mobile music album retrieval system is implemented on the basis of WIPI, and is now providing pilot services.

As wireless internet market grows rapidly, demands of various contents in wireless internet are significantly being increased. The mobile contents have been changed from single media contents such as text and voice to multimedia contents. As the technologies of cellular phone and broadband grow, the development of multimedia contents that can well represent the characteristics of users will be more increased. One example of such content developments is a ring-tone content service. Ring-tone content services have been changed from existing simple ring-tone to various sound services that depend on characteristic of user. In this paper, we design and implement a multimedia greeting system for the next generation mobile content service. Our system produces multimedia greeting contents using various multimedia contents and represents the characteristics of users through the elevation of ring-tone content services.

On the internet phone or PSTN(Public Switched Telephone Network), the automatic callback is an useful service in the case of busy state when one user calls the other. By using this service, automatic redial is possible when the other party hangs up. However, in the basic automatic callback service, the user who wants callback should wait until the other party hangs up even in the case of emergency. Therefore in this paper, to solve this problem we have extended CPL(Call Processing Language) and, within user system we have included and linked this extended CPL processing module and dialog event package which processes SIP INVITE initiated dialog state informations. We have implemented this system for being used in SIP(Session Initiation Protocol)-based VoIP(Voice over IP) system.
