Advanced collaboration environments (ACEs) where remote participants can cooperate with natural interaction, the
display service plays the most significant role. With enhanced
wide-screen display support, the quality of experience
(QoE) improves since it allows participants to share visual as if they are having a face-to-face meeting. Also, it is
important to visualize diverse types of media over various display devices with different resolutions and sizes. Thus,
there have been several existing efforts for interactive and networked display supports for advanced collaboration. In this
paper, by extending, we propose a clustered networked display system for SMeet (Smart Meeting Space for ACE),
dubbed as SMeet One Display. The proposed SMeet One Display system has several key features such as 'support for
heterogeneous display devices as one virtual display' and 'enhanced efficiency in terms of system resource management'.
Multi-party collaborative environments based on AG (Access Grid) are extensively utilized for distance learning,
e-science, and other distributed global collaboration events. In such environments, A/V media services play
an important role in providing QoE (quality of experience) to participants in collaboration sessions. In this
paper, in order to support high-quality user experience in the aspect of video services, we design an integration
architecture to combine high-quality video services and a high-resolution tiled display service. In detail, the
proposed architecture incorporates video services for DV (digital video) and HDV (high-definition digital video)
streaming with a display service to provide methods for decomposable decoding/display for a tiled display
system. By implementing the proposed architecture on top of AG, we verify that high-quality collaboration
among a couple of collaboration sites can be realized over a multicast-enabled network testbed with improved
media quality experience.
Multi-party collaborative environments are extensively utilized for distance learning, e-science, and other events for distributed global collaboration. In such environments, improved media service is expected to improve QoE (quality of experience) by better participants' perception in collaboration session. In this paper, we design and implement a high-quality video service attempted to be operated with a multi-party collaborative environments, Access Grid (AG), over heterogeneous networks. The proposed service uses the combination of high-quality video formats, network monitoring, and network-adaptive transmission. Its primary application is to provide seamless high-resolution video delivery service by considering one-to-many aspect of video distribution in AG-based multi-party collaborative environments. The implementation results are evaluated over a multicast-enabled network testbed and the experiment results verify the improved video service capability.
