타일 디스플레이 시스템은 여러 로컬(및/또는 원격) 참가자가 출력이 대규모 및 고해상도 타일에 표시되는 일부 공유 애플리케이션을 사용하여 협력하는 CSCW(컴퓨터 지원 협력 작업) 환경으로 사용되었습니다. 디스플레이는 디스플레이당 하나의 PC로 구성된 PC 클러스터에 의해 제어됩니다. 효과적인 협업을 위해서는 각 원격 참가자가 제목 디스플레이 시스템의 모든 CSCW 활동을 실시간으로 인식해야 합니다. 본 논문에서는 제목 표시 시스템의 모든 활동을 캡처하여 원격 참가자에게 실시간으로 전달하는 메커니즘을 제시합니다. 제안된 메커니즘에서는 모든 PC의 화면 이미지가 주기적으로 캡처되어 PC에서 캡처된 이미지를 저장하기 위해 별도의 버퍼를 유지하는 병합 서버로 전달됩니다. 메커니즘은 각 버퍼에서 하나의 타일 이미지를 선택하고, 이미지를 병합하여 전체 타일 디스플레이의 스크린샷을 만들고, 관심 영역(ROI)을 클립하고, 이를 압축하여 원격 참가자에게 실시간으로 스트리밍합니다. 제안된 메커니즘의 기술적 과제는 타일 디스플레이에 동시에 표시되는 타일 이미지가 적절하게 병합될 수 있도록 병합을 위해 각 버퍼에서 하나씩 타일 이미지 세트를 선택하는 방법입니다. 이 논문에서는 세 가지 선택 알고리즘을 제시합니다. 순차적 선택 알고리즘, 캡처 시간 기반 알고리즘, 캡처 시간 및 시각적 일관성 기반 알고리즘. 또한 동일한 병합 타일 디스플레이 이미지에서 여러 다른 ROI를 동시에 클리핑하고 원격 참가자가 요청한 비디오 인코더로 압축한 후 전달함으로써 타일 디스플레이 시스템의 여러 가상 카메라를 원격 참가자에게 제공하는 메커니즘을 제안합니다. 자신의 ROI를 대화형으로 변경하고 크기를 조정함으로써 원격 참가자는 타일 디스플레이에서 활동을 효과적으로 확인할 수 있습니다. 3에 대한 실험

Abstract: The tiled-display system has been used as a Computer Supported Cooperative Work (CSCW) environment, in which multiple local (and/or remote) participants cooperate using some shared applications whose outputs are displayed on a large-scale and high-resolution tiled-display, which is controlled by a cluster of PC's, one PC per display. In order to make the collaboration effective, each remote participant should be aware of all CSCW activities on the titled display system in real-time. This paper presents a capturing and delivering mechanism of all activities on titled-display system to remote participants in real-time. In the proposed mechanism, the screen images of all PC's are periodically captured and delivered to the Merging Server that maintains separate buffers to store the captured images from the PCs. The mechanism selects one tile image from each buffer, merges the images to make a screen shot of the whole tiled-display, clips a Region of Interest (ROI), compresses and streams it to remote participants in real-time. A technical challenge in the proposed mechanism is how to select a set of tile images, one from each buffer, for merging so that the tile images displayed at the same time on the tiled-display can be properly merged together. This paper presents three selection algorithms; a sequential selection algorithm, a capturing time based algorithm, and a capturing time and visual consistency based algorithm. It also proposes a mechanism of providing several virtual cameras on tiled-display system to remote participants by concurrently clipping several different ROI's from the same merged tiled-display images, and delivering them after compressing with video encoders requested by the remote participants. By interactively changing and resizing his/her own ROI, a remote participant can check the activities on the tiled-display effectively. Experiments on a 3
