VRVS: What it is ?VRVS: What it is ?

The Virtual Rooms Videoconferencing System has been developed by Caltech since 1995 to provide a world wide videoconference service for education and research communities.

VRVS is a realtime distributed system which provide a scalable communication infrastructure for large collaboration dispersed all over the world.

Different technologies and protocols are supported (and mixed) and allow users to connect their preferred videoconference.

Supports Mbone, H.323, SIP, QuickTime, Access Grid, JMF and MPEG2.

The system is composed of 1 main server and several reflectors (network servers) spread around the world.

VRVS Web Service DesignVRVS Web Service Design

Unified Web User Interface to schedule and join/leave a meeting independently of the application.

Multi-platform: Windows, Linux, MacOS and Unix Easy to use: Everybody (from 4 to 77 years old) knows

how to click on a web page today. Not true for running a VCR

Virtual Room Concept, Scheduling; Create a virtual space were people can exchange real-time information

Join or Leave a Collaborative session anytime. Do not need to know in advance how many participants and booked ports capacity. Just announce the meeting and people will join from anywhere.

Full Documentation and Tutorial Self service: Don’t need a technician or expert to

organize and join a conference

VRVS Reflector ImplementationVRVS Reflector Implementation Avoids Duplication of Streams on a given Link Can be set to Unicast or Multicast mode or both Connection peer-to-peer with neighbors network servers. Connectionless (more reliable to network breaks) Enables Optimized Routing Enables Bandwidth Control Provide low latency communication Could be use for real-time interactivity or broadcast Provide elegant solution to cross firewall/NAT Remote Management Features. Compliant with IETF RTPv2 Protocol, ready for new applications.

servers to find a better network path.. Improve Security (Firewall, NAT, Authentication,

Encryption)

Develop a pure peer-to-peer VRVS reflectors network to be able to handle thousands of parallel sessions

Wireless/Mobile Client Integration: User Interface dedicated for small screens Integration of low end client:

Provide dedicated software clients (VVP, JMF)Transcode streams to lower bandwidthSupport MPEG4

Integration of new hardware/software for high-end interactivity. Developed a multipoint videoconferencing system based on

MPEG4 compression standard. Developed a system using HDTV standard If affordable hardware

devices available.

Virtual Access GridVirtual Access Grid

User can connect to either unicast or multicast videoconferencing with full supported features

User can create his/her own virtual AG node and virtual venues and integrated into VRVS

Different Video modes possible:Voice switched: default mode for H.323 clients. one

video stream at a timeTimer switched: browse through all the video based

on preset timer. One video stream at a time.Selected Streams: Click among the video participants

to view selected video streams (one or several streams available).

All Streams

Conclusion: We believe that VRVS offers the following unique differentiators:

Usability – VRVS’ web-based user interface is easy to use and allows almost any desktop of videoconference suite to connect to a VRVS virtual room conference with only few clicks. Its default client apps enable multi-standards audio, video and data collaboration.

Scalability – VRVS scales up with the needs for quality and volume more elegantly and beyond anything possible now.More simultaneous participants in a same virtual

roomMore simultaneous virtual room conferencesWider range of video and data sharing quality

Page 31: Global Platform for Rich Media Conferencing and Collaboration

Flexibility – VRVS allows inter-operation of collaborative communications between end points of various audio, video and data sharing capabilities as well as different types of connectivity.

Efficiency – VRVS server software makes efficient use of bandwidth by routing required information only to various nodes.

Ubiquity – VRVS’ ease-of-use and scalability unlocks the value of network-based collaboration tools and allows anyone, anywhere, anytime to improve their collaborative experience.

Robustness – VRVS is field tested on a large scale for a long period of time. It has demonstrated exceptional reliability and simplified its deployment and use beyond anything available today (except maybe POTS and email!)

Web based interfaceWeb based interface

VRVS provides a natural and intuitive interface to organize and manage your meetings. Several interfaces let you see in 1 shot all current conferences, let you book a new one in 3 clicks. Several academic communities are handled by VRVS. Each one has its specific Virtual Rooms. VRVS manages multi international time zones in a transparent way. Its use do not require technical knowledge nor technician action.
