2 What is Data Collaboration? Data Collaboration Standards Approaches to Data Collaboration Section Overview

3 A “third stream” in addition to audio and video A shared electronic document A view of an electronic workspace A shared interface to a running application A one-time, impromptu or planned engagement A persistent, group electronic workspace Synchronous or asynchronous What is Data Collaboration?

4 Classroom: Shared whiteboards, slides, browsers; chats and polling/quizzing; curriculum planning, course design and repositories Administration: Proposals, budgets, status reports Research: Modeling/simulation, visualization, remote control Medicine: Collaborative discussions, remote diagnosis Typical Uses

5 Whiteboard Chat or Instant Messenger Shared Documents (Still Image) File Transfer Shared Applications Remote Control Pointers Surveys, Polling, Quizzing Recording Telephone and/or VC Bridges Video Streaming Animation Support Chair Control Scheduling and Timers Agendas for Meetings, Classes Announcement Boards Participant List, Status panels Management Console Directories Logging, Tracking Security -Authentication -Encryption Shared Repository, Meeting/Class Archives Features & Functions

6 T.120 Standard  Layered Services  Common Protocol - Network Independent  Protocol Data Units  P2P Communications Standard Applications -Still Image and annotation -Multipoint binary file transfer -Generic application template Non-standard Applications Data Collaboration Standards

7 Approaches Remote Data Display Interactive Data Collaboration Shared Persistent Virtual Workspaces

8 With a projected image: Share a PowerPoint or other presentation Share display of web browsing Demonstrate an application Provide user assistance or training Share whiteboard sketches and text Remote Display

9 Methods Scan converters Advanced proprietary solutions Band In-band (on a video channel) Out-of-band (on an independent data channel) Remote Display

10 Scan converters –Converts a high resolution PC RGB signal to a lower resolution composite video signal –Cheap and easy to use –Fair to poor resolution (no small fonts) –Uses a (the) main video window (in-band) Remote Display

11 Proprietary solutions - Polycom Visual Concert FX –Local RGB video from PC, sound from mic to far-side video or projector/display –Easy to use but requires high-end video conferencing appliances –High quality, native resolution –Uses a separate window (out-of-band) Remote Display

12 Proprietary solutions - Polycom SNAP! –Transmits JPEG snapshots of desktop or application to a Polycom appliance –Free and relatively easy to use –Low resolution like scan converter –Windows only Remote Display

13 Share a desktop or a window to: Co-browse the web Jointly work on whiteboard diagrams Jointly update a document Share a running application to: Jointly steer its operation Provide support or training on its use Troubleshoot problems Use valuable, limited resources Define a meeting space Interactive Data Collaboration

47 Bandwidth requirements Browser based and centralized tools may be influenced more by network latency and virus problems/DoS attacks. Sustained workflow Newer tools have features that support persistent environments as well as ad-hoc meetings. Availability Commercial tool pricing for general (mass) use is probably an obstacle. Project pricing may be reasonable. Closing Remarks

48 Methodology While many use open standards for individual elements, overall architectures and interfaces tend to be unique and even proprietary. Perspective Venue or perspective must be chosen: desktop, meeting room, classroom, others. Ease of use Tools are not always intuitive. Substantial training may be required. Closing Remarks
