Interactive 3D HD video transport for e-science collaboration over UCLP-enabled GLORIAD lightpath
Jo, Jinyong,Hong, Wontaek,Lee, SeungJoo,Kim, Dongkyun,Kim, JongWon,Byeon, OkHwan Elsevier 2006 Future generations computer systems Vol.22 No.8
<P><B>Abstract</B></P><P>Emerging large-scale applications for e-science and Grid require end-to-end lightpaths that need to be dynamically provisioned with QoS (quality of service) guarantees. In this paper, an e-science collaboration is demonstrated as a part of iGRID2005, where an interactive 3D HD (high definition) video transport is realized over an inter-continental lambda integrated facility on 10 Gbps GLORIAD links. To realize real-time interactive (2-way) collaboration among scientific researchers, the 10 Gbps end-to-end user-controlled lightpath between Korea and USA is dynamically provided with very high network performance. Both uncompressed and stereoscopic HD videos are then exchanged between participating sites. Thus, we verify the potential of proposed e-science collaborations by discussing underlying lambda networking infrastructure, UCLP-enabled dynamic lightpath provisioning, HD video system setup and integration, and demonstration results.</P>

Software-defined home networking devices for multi-home visual sharing
Jinyong Jo,Soyeon Lee,JongWon Kim IEEE 2014 IEEE transactions on consumer electronics Vol.60 No.3
<P>Existing home-networking protocols do not robustly incorporate universal connectivity among multiple homes, which leaves their use restricted to a single home. In addition, even in a single home network, new functional requirements ask for more diversified forms of networking control. This paper presents in-home consumer electronic devices that incorporate the emerging SDN (Software Defined Networking) paradigm. The proposed devices enable ondemand provisioning for protocol-agnostic home networking and thus provide a high degree of flexibility for intra-home networking as well as wider connectivity for inter-home networking. The feasibility of the prototype devices is verified by realizing a multi-home visual-sharing scenario and by supporting diverse future scenarios.</P>
imCast: Studio-Quality Digital Media Platform Exploiting Broadband IP Networks
JO, Jinyong,KIM, JongWon The Institute of Electronics, Information and Comm 2010 IEICE transactions on information and systems Vol.93 No.5
<P>The recent growth in available network bandwidth envisions the wide-spread use of broadband applications such as uncompressed HD-SDI (High-definition serial digital interface) over IP. These cutting-edge applications are also driving the development of a media-oriented infrastructure for networked collaboration. This paper introduces <I>imCast</I>, a high-quality digital media platform dealing with uncompressed HD-SDI over IP, and discusses its internal architecture in depth. <I>imCast</I> mainly provides cost-effective hardware-based approaches for high-quality media acquisition and presentation; flexible software-based approaches for presentation; and allows for economical network transmission. Experimental results (taken over best-effort IP networks) will demonstrate the functional feasibility and performance of <I>imCast</I>.</P>
Light-weight 소프트웨어 CODEC을 이용한 2K 영상의 실시간 네트워크 전송에 관한 연구
조진용(Jinyong Jo),박종철(Jongchurl Park),문정훈(JeongHoon Moon),곽재승(Jaiseung Kwak),김종원(Jongwon Kim) 한국통신학회 2008 韓國通信學會論文誌 Vol.33 No.10B
실시간 및 고품질 특성에 대한 멀티미디어 요구 증대는 응용의 광대역화를 촉진시키며 네트워크 및 시스템 측면의 요구 사항을 증대시킨다. 본 논문은 고화질 HD(high definition) 영상을 소프트웨어 기반으로 실시간 압축하는 DXT 부호화와 초고속 네트워크 전송을 효과적으로 결합하는 프로토타입 시스템의 구현을 다룬다. 특히 구현된 프로토타입 시스템을 통해 광대역 응용에 요구되는 미디어 압축과 전송을 위한 네트워크 및 시스템 특성을 살펴본다. 개발 구축된 시스템의 성능 검증을 위해 과학기술연구망에 테스트베드를 구축하고 종단 간 전송 실험을 통해 효용성을 입증한다. The growing availability of broadband multimedia applications are providing strict real-time services and enabling users to feel much interactivity as well as `sense of presence'. In that sense, there would be increased demand for what network and system have to do to fulfill the user expectations. In this paper, we implement a real-time multimedia application which make use of real-time DXT CODEC and investigate what the challenges of networking and system are. We carry out various experiments over a research network test-bed to evaluate the performance of our proposals.
