  1. Sid Ahuja VP Converged Networks and Services Research Multimedia Research Viewpoint and vision

  2. What is Multimedia? • Not just another medium (media type)? • Audio, video, data, .. • Aggregation of two or more different medium? • Integration of multiple medium in common applications • Multimedia mail (includes voice, data and images) • Real time experience in multiple media around a common event (people centric.. Not machine centric)

  3. Real Time Multimedia Experience • Daughter’s Birthday Party • Screaming kids everywhere (rich interactive multipoint audio) • Colorful and messed up clothes (rich multipoint video) • Kisses and hugs (rich tactile feedback) • Getting hit by an errant pie (VERY rich tactile feedback) • Going on a Space Mountain ride at Disney • The world rushing by (high speed audio, video) • Hanging on to dear life on a huge drop (g-forces) • Losing your hat on the third turn (air whizzing by ) • These are IMMERSIVE experiences • Being hit at the same time in many different ‘senses’ • Produces a feeling of ‘being there’

  4. Multimedia in Entertainment • Multimedia Presentations (multimedia content) • DVD Movies .. Limited to big production houses • Business presentations (data + A/V clips) • Multimedia mail • Audio and Video attachments to email • MMS .. Multimedia messaging in wireless • Video clips on the Internet • Asynchrounous use of Multimedia content

  5. Networked Multimedia • Real time multimedia collaboration (why are we not using it?) • Systems being built since late 80’s .. No common standards • Confusion about the experience (document sharing, Video conferencing) • Lack of common signaling and bandwidth • Multimedia Books /classrooms • No standard today • Mostly one-to-many videocast of a lecture • Can be truly interactive (from each user’s point of view) • Interactive Video Games • Shared mulitmedia experience • Virtual video, audio and other media (tactile feedback) • Networked video games .. No shared audio, local video • No tools for the consumer

  6. Challenges .. Vision • Billions of sources (every person a consumer and producer) • Cheap devices for capture and interface • Tools for representation, storage and movement • Network for movement • Already happened to the Text world • Trillions of experiences • Representation and indexing • Not just one kind of video … any set of pixels ..any rate • New media types .. Tactile, temperature, etc. • Content identification and ownership • Encryption • Watermarking • Easy sharing with multiple people • Multicasting • Group communication support

  7. New Applications Push-to-view (Always-On)

  8. New Applications User’s rich video world User has a ‘personalized’ selection of low-bitrate, Always–On, interactive video channels The Always-On video channels can be sourced from: • Entertainment broadcast stations • Roving reporters .. e.g. an embedded reporter in Iraq • Monitoring sources: traffic intersection, kid’s room, factory floor,etc. • Instantaneous person to person video connection (like Push-to-talk to limited set) • Personal Video mailbox Video channels are MPEG4 .. based • Quick set-up is required for providing Video channels from millions of sources • Network infrastructure required to manage totality of Video sources • Bandwidth per user can be from 64 Kbits/sec to 1 Mbits/sec based on quality and number of Always-On channels.

  12. New Research Directions • Rich definition and representation of mulitmedia content • Identification and copying • Tools for masses for creating and sharing content • Next generation network infrastructure • New signaling infrastructure (SIP+) • Enough capacity for end points • New group support • QOS for real time • Persistence .. How to save for posterity

  13. SIGMM .. Take the Lead • Wireless world …3GPP / 3GPP2 • Wireline world .. W3C , IETF, TV Industry • Multimedia Books …standardize content • Tools for the masses • Facilitate multimedia forums • Hold next retreat as a virtual retreat
