Title: DancingQ on HDTV (speaker: ANF DY Kim)

A special task force team called 'DancingQ' has been formed within ANF
for performing arts on the Internet. The first performance was done
successfully on Nov. 7 this year using DVTS. The second event is being
planned for the Buddha's birth day next year under the theme 'Buddha
on the Net'. The techology challenge this time will be HDTV and IPv6.
This is going to be a world wide event involving New York, Paris,
Barcelona, and other major cities around the globe.
 


Title: More Pixels and Samples: High Resolution Media Streaming (speaker: USC IMSC R. Zimmerman)

Presently, digital continuous media (CM) such as audio and video are well
established as an integral part of many applications and the technological
trends point towards continued improvements in quality for both audio (e.g.,
more channels) and video (higher resolution) streams.  High quality media
require lots of bits and their management has until recently required
specialized equipment.  However, improvements in information technology now
present us the opportunity to apply more commodity hardware and hence enable
many more interesting applications.  The Integrated Media Systems Center at USC
explores such applications in the education, communication and entertainment
spaces in addition to pursuing basic research.  This talk will provide an
overview of some of IMSC's activities, from the established Remote Immersion
System to the emerging Distributed Immersive Performance.

To enable the above and other applications an efficient media stream coordinator
is needed that can manage the recording, transmission, and playback of many
different data streams simultaneously.  We describe our design for a
High-performance Data Recording Architecture (HYDRA) with the goal of using a
unified paradigm that integrates multi-stream recording, retrieval and control
in a coherent manner.  HYDRA aims to provide the same services for all media,
independent of their bandwidth requirements, resolution or modality.
 


Title: Delivering Reality to the Desktop: HDTV and SDTV applications
  (speaker: Internet2/ResearchChannel Michael Wellings and James W DeRoest)

 
This presentation will describe several experiments and demonstrations of high
Bandwidth networking that enables the convergence of broadcasting and computing. 
The experiments were developed at the University of Washington by the ResearchChannel. 
Experiments have ranged from the 2000 National Association of Broadcasters
demonstration of Streaming High Definition Television over Internet in the
Sony NAB booth, 270 Mbps HD video transmission to Busan / APAN 2003,
19.2Mbps ATSC 1080 / 60i HD from Seattle to Los Angeles, to uncompressed
HD transmission, featuring 1080/60i HD video at 1.5 Gigabits as Packet over
SONET IP from Seattle to Denver.  Using advanced networks and next generation
Internet2 are only part of these high bandwidth applications and the interfaces,
system integration and architecture issues also had to be resolved in these
successful projects. The presentation will discuss:
Video On-Demand interface for HD and MPEG-2 playback
Current progress on our HD desktop client featuring ATSC 19.1 Mbps HD available as Video on Demand and multicast
High-quality media delivery using high speed networks
Description of our wide and varied content delivery applications ? both SD and HD, for enhanced listener/viewer experiences
where we are going with all this in our radio and TV operations
media archive search and archive issues
The convergence between computing and broadcasting, and what the future may hold
 


Title: Access Grid with High Quality DV Video (speaker: K-JIST JW Kim/DH Yi)

The Access Grid (AG) technology provides remote collaboration environment to
overcome limitations of existing video conferencing systems. With the evolution
of AG Toolkit, various components including  shared presentation and shared
web browser have been developed to improve user convenience in AGTk 2.1.
However, since the video transmission services in the AG rely on a VIC tool
that only supports outdated H.261-based codec in small picture size, it has
limitation in supporting immersion to the participants. Focusing on this media
quality issue, we are currently undergoing an enhancement project of AG video
service so that the video interface is automatically selected among various
video interfaces (e.g., DV, HD, Stereo..) according to the capability and
network status among AG nodes. In this presentation, we will report current
progress and demonstrate the DV addition to the AG video service.

Title: HDV over IP in Korea (speaker: KAIST J.B. Lee) Remote Presentation

An on-going development activity on HDV over IP in Korea will be introduced. Targeting
January, 2004, a software-based system that can transfer 19.2Mbps MPEG-2 HD Stream
from JVC HD Camcorder is being developed. The output software including source codes
of this project is planned to be open to public. If time permits, we will briefly
introduce another HD IPv6 streaming system developed by ETRI, Korea, which is tied
with CoS-based QoS provisioning tools.
 


Title: HDTV Transfer System Demonstration over APII/JGN
  (speaker: Kyushu Univ. K. Okamura / Hiroshima University Reiji Aibara)


In this presentation, the implementation of HDTV transfer system over
Internet is explained.  This implementation uses Victor's JY-HD10 and
MPEG2 is used for the translation. We use Linux as the platform and
some special PCI cards to decode MPEG2 to HDTV. In my talk, this
implementation detail will be shown and if possible, the demonstration
of this system between Japan and venue using APII/JGN will be
presented.
 


Title: One-to-Many Video Delivery using Relayed Multicast Scheme (ETRI SG Kang)

During the last several decades, there have been a lot of research works
to deliver video data from one sender to multiple receivers. IP multicasting
technology is one of the major achievement that multicasting service is
provided by the network functions. However, the use of IP multicasting
technology can be restricted if any Router doesn't support IP multicasting
functions. The overlay multicasting technology was developed to overcome
these restrictions. In this presentation, one of the new overlay multicasting
scheme, relayed multicast protocol(RMCP) will be introduced. A great number
of receivers can be accommodated for multicasting services at the same time
when using RMCP. Also, the experience of one-to-many video delivery using relayed
multicast protocol over the Internet will be introduced at the presentation
