연구실소개

  • Networked Computing System LaboratoryUpcoming future information network is expected to be based on the Internet by integrating the versatile networks together. The research in Networked Media Lab aims at the development of tools, algorithms, and paradigms for the “Reliable and flexible delivery of integrated media (video/audio/graphics/data) under the futuristic wired/wireless integrated network environment”. We wishes to investigate issues including the followings to realize our research objectives:Immersive Media Delivery- Resilient and synchronized media distribution over multicast-enabled networks: Synchronized multicast media streaming with adaptive playout, Resilient/Layered multicast with source error resiliency and scalability, and Reliable media distribution by IETF’s RMT.
    – Distributed and massive media distribution via CDN: Media delivery over content distribution framework with proxy/cache, and distributed media streaming via P2P and application-layer multicasting.
    – Immersive and interactive media contents generation and delivery: Integrated media content generation extending MPEG-4 system and X3D; immersive and interactive media delivery and high performance networking over next-generation optical Internet (Access Grid and Networked Virtual Environment).

    Ubiquitous Networking

    – Ubiquitous media networking with mobility, QoS, and multicast support: Wireless media delivery over 3G/4G wireless Internet and IEEE 802.11-based Wireless LAN that includes mobility, QoS, and multicast support.
    – Persistent and autonomous information sharing via P2P content networking and sensor networking: Content-based overlay networking design via P2P and persistent AdHoc and sensor networking.
    – Dynamic media delivery over highly fluctuant networks for graceful degradation (bandwidth, delay, and error/loss): Dynamic network adaptation with layered prioritization, rate/flow control, source-network coordinated error control, and incorporation of IETF’s TCP-friendly end-to-end congestion control.
    – Robust and scalable media representation (compression/transcoding): Encoding/transcoding for scalable/error-resilient representation and its prioritized packetization by layered relative priority index (layered RPI) focusing on the multi-functional aspects of ISO/IEC JPEG-2000 image, ITU-T H.263++/H.264 video, and ISO/IEC MPEG-2/4 audio/video/system.

    Networking support

    – Efficient networking support for media delivery via adaptive network QoS/resource management: Futuristic QoS architecture by IETF IntServ and DiffServ integration, policy-based network QoS management, and end-to-end performance monitoring and management.
    – Flexible and transparent media service protocols for next-generation networks and GRID & Home Network middleware: Media service protocols and architectures such as IETF’s RTP/RTCP/RTSP/SDP/SIP, ISO/IEC MPEG-4’s DMIF, and ITU-T’s H.323/H.324M; Media networking linked with GRID middleware and Home Network (UPnP/HAVi/Jini).
    – Universal media access framework with security and intellectual property management: MPEG-7’s Ds/DS/DDL, W3C’s XML/RDF/SMIL, WAP Forum’s WML, IETF IPSEC/MSEC, and MPEG-4 IPMP by watermarking and encryption tool.
