1. New topics on DVTS Kazuhiro Mishima Keio University, Graduate School of Media and Governance Doctor Course

2. Agenda Latest update of DVTS for WindowsXP Session signaling issues for the next generation of DVTS

3. Latest update of DVTS for WindowsXP

4. Released ver.0.0.2 rev.1 Some minor bugs are fixed –Unknown format : 0 problem depends on the environment SSM capable –IPv4 SSM ok! –IPv6 SSM ng WindowsXP doesn’t support MLDv2

5. ver.0.0.2 rev.1

6. Next generation of DVTS for WindowsXP (0.0.3.x?) Multi-format –DV –MPEG2-TS(HDV) Environment Adaptation –CPU –Memory –Network →Auto configuration, Auto adaptation

7. Beta release (only support Multi-format function) DVTS (DV mode) –receive DV stream –send DV stream –IEEE1394 input support –IEEE1394 output support –PC Monitor output support DVTS (HDV mode) –receive HDV stream –send HDV stream –IEEE1394 input support –PC Monitor output support MPEG2 Video Decoder is required (WindowsXP doesn’t have any MPEG2 Video Decoder)

8. MPEG2 Video Decoder Checked –Elecard MPEG-2 Decoder and Streaming Pack (Product) http://www.elecard.com/download/ –GPL MPEG1/2 DirectShow Decoder Filter (Free) http://sourceforge.net/projects/gplmpgdec/ Unchecked –ffdshow (Free) http://sourceforge.net/projects/ffdshow –others…

9. HDV mode DVTS for WindowsXP compatible GUI

10. Download Here!! http://www.sfc.wide.ad.jp/DVTS DVTS 0.0.2-1 http://beta.dvts.info/setup-0.0.2-1.exe DVTSng 0.0.0-0 http://beta.dvts.info/setup-0.0.0-0.exe

11. Session signaling issues for the next generation of DVTS Design and Implementation of area-based session directory system (Channel Reflector)

12. Session Signaling Session Manager –Control some DV stations (sender, receiver…) Session Directory –Find DV some sessions

13. Session Directory issues Session Directory –SDP+SAP for multicast Issues –Deployment –Scalability no mentions for “Global Internet” –Transmission Area SAP uses multicast TTL for limiting Many many troubles.. Well deployed??

14. Area-based Session Directory System like a DNS (Root, Area, Contents Manager) like a Route Reflector (BGP)

15. Channel Reflector Multicast Session Directory System Features –Web-based application Apache + Perl + MySQL + LWP –SDP based session description –Tree architecture –Scope architecture Manage channels dividing by the content’s area(=scope) –Refer to RFC4435 (from IETF MMUSIC-WG) Framework of the IMG (Internet Media Guides)

16. Screenshots under development version

17. Channel Reflector (cont.) Architecture –Root CR –Parent CR –Child CR –Friend CR –Scope Label

18. Channel Reflector (cont.) Architecture –Peer CR Peer between Root CRs

19. Implementation Status Admin GUI – now implementing… –Manage CRs –Manage ScopeLabels –Manage Channels User GUI (Customizable) –View Channels like a TV Guide –Search Channels
