Our Digital Carousel enables user to share media objects through media synchronization mechanism. We implemented the Digital Carousel so that the users participated in collaborative work may refer shared media or error objects as the same view to others. This paper explains the design and implementation of the EC_DXS(Error Control in Digital Carousel System). EC_DCS is a system that is suitable for detecting sharing and recovering software error based on multimedia CSCW(Computer Supportes Cooperated Work). With error sharing system, a group cooperating users can share me. applications. From the perspective of multimedia collaborative environment, an error application becomes another interactive presentation error is shared with participant engaged in a cooperative work.

Our Digital Carousel enables user to share media objects through media synchronization mechanism. We implemented the Digital Carousel so that the users participated in collaborative work may refer shared media or error objects as the same view to others. In this paper, we discuss a method for increasing reliability through fault tolerance. We describe the design and implementation of the ER running on distributed multimedia environment. ER is a system which is able to recover automatically a software error based on distributed multimedia. This paper explains a performance analysis of an error recovery system running on distributed multimedia environment using the rule-based DEVS modeling and simulation techniques. In DEVS, a system has a time base, inputs, states, outputs, and functions.

In this paper, we discuss a model for increasing reliability of data through N screen server and client model environment. Our Digital Carousel enables user to share media objects through media synchronization mechanism. We suggest the Digital Carousel system based on CoAP(Constrained Application Protocol) for N-Screen so that the users participated in collaborative work may refer shared media objects as the same view to others. With this sharing system, a group cooperating users can share applications data. This paper explained a performance analysis of a system with function comparison running on multimedia collaboration work based on CoAP and N screen techniques.

When a user visits a specific site through various devices, the hero image located in the main area that can be viewed without scrolling includes multiple slides and has various carousel navigation patterns. While there is a negative perception that the carousel design does not receive the user's choice due to the hidden slide, it can be seen that its usefulness can vary depending on the user's context. In addition, the navigation pattern of the carousel design is the factor that has the greatest influence on the user experience. The left and right arrow navigation pattern, the bottom pagination navigation pattern, the accordion type navigation pattern, the thumbnail type navigation pattern, the divided slide type navigation pattern, and the last. It could be divided into six types of left and right slide navigation patterns.

Various kinds of data broadcasting services can be offered using a return-channel in digital broadcasting TV compared to analog services. In these data broadcasting environments, several data(associated with TV broadcasting programs, or not) are provided to the TV audiences except for audio/video broadcasting data. In this paper, a structure of data manager for data/object carousel, based on data broadcasting protocols, was proposed for data broadcasting services using a return-channel, and were supported to the production technologies of DTV contents. These contents application techniques for DTV will be implemented with this data manager in MPEG2-TS data broadcasts using PID(Packet ID).

We propose a new data carousel scheduling algorithm for on-demand data broadcasting in DMB. The server divides data items into two sets named hot and cold, according to request statistics from clients. When constructing a data carousel, hot items are placed periodically with their upper limit of broadcasting frequency. If there are empty slots after placing hot items, cold items with high request ratio are placed until the carousel is full. A cold item is broadcast only once in the caroulsel. For the response on clients' requests, our proposed scheme is shown to have high success ratio with short waiting time.

Unlike traditional analog broadcasting, digital broadcasting provides users with various additional services that we have never seen before. To receive these kind of services. data broadcasting includes not only audio, video signal, but also additional data associated with the program. In this paper, we present the efficient parsing and caching mechianism for data carousel in digital broadcasting set-top box. In order to speed up the process of parsing, we use the Message Pool that stores elementary_pid syntax of DSM-CC message packets.

국내외 방송환경이 디지털로 급속히 변화함에 따라서 지상파, 케이블, 위성 등의 기존 방송망을 이용하며 서비스 제공자가 제공하는 데이터 서비스를 사용자가 요청 할 때 전송하는 데이터 방송은 기존의 비디오, 오디오 방송 프로그램 이외에 방송과 관련된 데이터 또는 방송과는 직접 관련이 없는 순수한 데이터를 제공하게 되었다. 데이터 방송 표준 단체인 DVB(Digital Video Broadcasting)에서는 데이터 방송 시 데이터 전송 기법으로 데이터 스트리밍(Data Streaming), 데이터 파이핑(Data Piping), 데이터 캐루셀(Data Carousel), 멀티프로토콜 인캡슐레이션(Multiprotocol Encapsulation), 객체 캐루셀(Object Carousel)을 제안하고 있다. 본 논문에서는 데이터 방송에 사용되는 데이터를 효율적으로 관리하기 위하여 메시지 캐슁과 모듈 캐슁을 기반으로 한 데이터 캐루셀 매니저 설계와 구현에 관한 내용을 다룬다.
