  1. The 3D Media InternetChallenges & Solution Paths Saarbrucken, Germany Thorsten Herfet Philipp Slusallek

  2. Problem Space • Audiovisual transmission - the „Core Application“ of the Future Internet • (3D)IPTV, (3D)Internet-TV, 3D Virtual Worlds, VoIP etc. • Bandwidth demands threat to exceed Internet infrastructure investment by 60% to 70%(*) • Actual Internet has been designed for data • Multicast is essential for many AV services • But MC support of protocols rudimentary (even SCTP, DCCP etc.) • Pure end-2-end paradigm (socket-2-socket) • Alternatives like Split-TCP and Partial Reliability still in a niche • Discussion around evolution vs. revolution ongoing • Revolutionary thinking and evolutionary implementation is the solution * Source: http://www.nemertes.com/internet_singularity_delayed_why_limits_internet_capacity_will_stifle_innovation_web

  3. Solution space • Transport must follow new paradigm • Predictable Reliability under predictable delay (PRPD) • Ingerently multicast enabled • Requires even new theory (capacity for predictable reliability) • Our proposals • AHEC Framework analytically and practically implemented (next slide) • Extensions for link-2-link implementation ongoing • Intelligent routers required, but evolutionary (each single one helps)!!! • Cost-based routing easily implementable • SLA‘s can be integrated into framework easily

  4. Hybrid Error Correction

  5. PRPD-Demonstrator

  6. 3D in the Future Internet • 3D still is not integrated into web • Content representation is 2D (DOM) • Most representations (VRML, X3D) bypass DOM • Solutions required for • Extending scripting languages (ECMAscript) • Notation to describe 3D scenegraphs (XML3D) • Flexible and extendible rendering (shader languages, ray tracing) • 3D displays are still in their infancy • Seamless choice between UHD-2D, HD-3D and SD-MV3D still not feasible
