Research Channel/Internet2 DVIP Exploration
We are exploring different technologies and methods of using DV over IP (DVIP).
The purpose is to explore and compare the quality of using DVIP to other methods of
transporting audio and video over IP. We will compare and contrast this technology to
the common video conferencing tools (H.323, MPEG1, MPEG2, Access Grid, VRVS)
and to common video streaming tools (Quicktime, Media Player, MPEG2, H.261). We
will also discuss the network resources and the endpoint equipment required to support
DVIP compared to the other technologies used for:
. point to point Video Conferencing
. multipoint Video Conferencing
. Streaming to PC desktops, both single & multiple streams
We will discuss the comparatively low cost of using the following tools
constructed by our friends in Japan:
. Sony "commodity off the shelf" (COTS) IEEE1394 capable Handycam
. DVTS software, freely available from the WIDE project
. CometDVIP PCI cards available from Fujitsu Research
We will also discuss the degree of difficulty deploying the DVTS software on different
platforms as well as simplicity of deploying the CometDVIP PCI cards.
We will discuss the need for networks that are both multicast capable and able
support a 30mb per second for each DVIP stream. We will share examples of the
successful deployment of DVIP at:
1. the Internet2 Fall Member Meeting, using multiple streams to support
stereoscopic video (3D) from three locations on WAN to support a
collaborative music performance
2. the Korean DanceQ performance, where unicast, multicast, IPv6 and IPv4
were used to make available a theatrical performance of traditional Korean
dance.
3. Internet2 Virtual Briefing of the Research Channel Briefing which included
multiple technologies
Discussion of these events will also include the necessary router configuration changes,
the required network switch capabilities, and the end point operation. We will also
share our experiences using this technology for both point to point as well as multipoint
video conferences across the Abilene backbone.
Future work and projects will also be shared, including the intersection of DVIP
with other deployed technologies (such as the Access Grid) as well as other popular
desktop platforms (OS X). We will also share the current deployment underway at
different Internet2 institutions related to distance education and remote consultation.
We will talk about the current CometDVIP work related to transmitting HDTV over IP.
This presentation will make clear the reasons one would prefer to use the DVIP
technology in many of these collaborative environments. Such reasons discussed will
include:
. the quality of the audio/video experience
. the low encoding/decoding latency
. taking advantage of high bandwidth networks
. low cost of necessary technology
The potential for using DVIP to extend the research and education mission of academic
organizations will be shared as well.
