  1. Commerce using MPEG-4 on Internet with QoS Application Production Process and tools Project Leader : Christian Bertin, CCETT christian.bertin@cnet.francetelecom.fr

  2. Applications • VIRTUGUIDE Application • Home shopping application for Turism Products (extended city trips) • VIRTUCAT Application • Home shopping application for Commercial Centre products (sport, video, etc.)

  3. VIRTUGUIDE Application You are following one of the 5 guides through Berlin : - Young overstyled blonde - History student - Charismatic artist type - Techno D.J.ane - Jobless coffeedrinking actor 360-degree prerecorded video sequence so you can see in any direction around you As you follow your guide through Berlin, you can see in addition to the 3D Video: • A set of recommended choices (appearing and disappearing) for interaction • A global map of Berlin with the guide position • A local map (zoom on global Berlin map) with the guide position

  4. VIRTUGUIDE Screen • HTML Page consisting in : • Applets (global map, local map, recommended choices) • MPEG-4 3D Scene with a video displayed on a hemisphere) • Problem : • Text display quality is not acceptable in VRML/MPEG-4 => Java AWT.

  5. VIRTUGUIDE ApplicationCharacteristics 360 degree shooting with a hemispheric mirror above the camera : 512x512 pixels Circular video to be mapped on a hemisphere Future : Video divided in 8 planar video segments Future : Only 3 or 4 Video segments sent at a time to be mapped on a cylinder

  6. VIRTUGUIDE Scenario

VIRTUGUIDE .VFF file (Virtuguide File Format) SEQ I_1 # Videosequence number FPS 25 # number of frames per seconds SHEET I_1_1 # sequence number TITLE "XP1-Rose in" - "Extended Version I.1.1-4!" # <BEGIN> <NXT> <Camera Rotation> BEGIN 0 I_1_1 0 PA #No PA$ PALINK IN OUT 1 "excuse me ..." 0 370 700 2 "hi, where are you up to ?"

  8. VIRTUGUIDE Production process • Audio-Video shooting (Filmakademie) • Audio-Video MPEG-4 encoding (LEP) • Scenario production (Filmakademie) • Scenario textual coding (Filmakademie, textual editor) • Screen implementation (CCETT, html pages, applets) • Scenario MPEG-4 coding (CCETT, VFF file parser => Textual BIFS update => MkScene BIFS encoder => Binary BIFS)

  9. VIRTUCAT ApplicationBike shop screen Do it yourself! Please select : - a frame, - a fork, - a wheel and you will see the result : a 3D model of your bike with all the selected elements together • You can go around the bike you are building yourself • You can browse the sets of frames, forks and wheels for selection • You can order your bike (BUY button) • You can go back to the shop selection

  10. VIRTUCAT ScreenCharacteristics • MPEG-4 Scene with : • 2D scene with 2D textures • 3D Bike Model • HTML pages for order form • Server ASP Script to handle the contents of the customer trolley and corresponding order form

  11. VIRTUCAT Production Process • 3D Commercial centre Tower Navigation production (Lightwave, 3D Studio Max, convertion to MPEG-4 with some limitations due to the Compositor • 3D Bike model Production (Filmakademie, 3D S. Max) • 2D Textures (Frames, Forks, Wheels) (Filmakademie, JPEG encoding) • Bike Shop Screen composition (CCETT, no 2D tool, text editor only)

  12. VIRTUCAT Production Process (continued) • EAI (Enhanced Authoring Interface) Java Programs (to get the selected bike elements and to position the bike elements) • ASP Script behind BUY button to run on the server (Finsiel)

  15. Electronic Commerce Requirement on MPEG-4 • We will use MPEG-4 only when MPEG-4 Tools and Servers offer : • User input to get Password, User ID, User Address, User Comments, Order Forms, Database Product Search Criteria, etc. • Dynamics in scene using scene skeleton and dynamic elements updated with information coming from a database (price, product description, product pictures, product videos) • Possibility to jump at a Random Access Point in an MPEG-4 scene
