| Objective |
This HDTV session is designed to provide attendees with an opportunity to discuss the latest development around the network-based delivery of HD (high-definition) video technology. Aiming to provide immersive experience to end users with HD quality video, lots of efforts are taking place to enable HD video contents over high-speed research networks. In this session, several on-going efforts on HD video delivery will be presented and discussed. |

| Agenda of Session |
1.Tutorial on HD/4K video and collaboration
Speaker: JongWon Kim (GIST) (90 min talk)
This tutorial talk intends to cover brief technology overviews on HD/4K video technologies (and its delivery over IP networks). It is then extended to collaboration environment technologies where HD video plays the key media for interactive collaboration. By suggesting the vision toward advanced collaboration environment, this talk will be concluded.
2.Internet HD WorkFlow: Cameras, Codecs, Edit Systems
Speaker: Mike Wellings and others from Research Channel
3.Real Demonstration using un-compressed HD streaming by i-visto under IPsec between Japan and Korea
Speaker: Koji Okamura (Kyushu Univ.)
4.Bi-directional Uncompressed HD Video System from GLORIAD-KR
Speaker: Juwon Park (from GIST on behalf of GLORIAD-KR (20 min talk)
This talk presents an update on the GLORIAD-KR(GIST/KISTI) joint development of cost-effective realization of uncompressed HD (high definition) video transport system over high-speed IP network. This
time, we will discuss about bi-directional support from a single box, which can improve the cost-effectiveness of uncompressed HD-based collaboration systems.
5.Introducing DV and HDV into the Access Grid
Speaker: Christoph (Willing from University of Queensland) (30 min talk)
At the University of Queensland Vislab, our development work with the
Access Grid tools concentrates on the AG's collaborative aspects,
usually through its Shared Application mechanism. Without the ability to
share applications, we don't have collaboration - just video
conferencing. However the project to be described here involves
enhancement of the well known vic video tool to incorporate DV and HDV
streams. It will include justification for initially using vic at all,
in particular the need to provide a DV/HDV solution suitable for all
platforms currently being used for Access Grid nodes. Apart from the
changes needed in order to both capture and render multiple DV/HDV
streams, we have implemented other changes including traffic shaping (to
prevent overwhelming under-resourced network equipment) and resizeable
vic windows (to accomodate multiple large format streams in restricted
display situations).
The presentation will also address the ramifications of introducing such
high bandwidth media streams (typically 30Mb/s each) in AG sessions
whose participants' network capabilities may vary considerably. In
addition to traffic shaping in vic itself, a new family of
{DV,HDV}Video*Services will be described which allow session
participants to choose which remote DV/HDV streams to view prior to any
DV/HDV traffic appearing on their networks.
Although this is a "work in progress", it is well advanced. Both Linux
and WindowsXP versions are now in the testing phase. A Macintosh OSX
version has also been commenced in an external institution (with our
guidance)
Finally, the presentation will address the problem of built-in latency
of camera derived HDV streams; firstly in terms of mitigating its
effects and, secondly, in terms of how to utilize raw component streams
from the camera to transmit in either uncompressed or machine compressed
formats.
