  1. Medical WG Technology session APAN 32 nd meeting at New Delhi HD- -SCR and Tele SCR and Tele- -Pointer Pointer HD Chairpersons: Ti-Chaung Chiang, National Taiwan University Torata N and Cao Duc Minh, Kyushu University Hospital. 1 HD-SCR: High Definition Streaming Combined Remote conference system Participating sites Participating sites New Delhi venue, IN Kyushu University Hospital, JP Fukuoka University Hospital, JP National Taiwan University, TW National Agency for Science and Technology Information (NASATI), VN Cho Ray Hospital, VN Advanced Science and Technology Institute (ASTI), PH University of the Philippines Manila, PH University of Hong Kong, CN Korea Institute of Science and Technology Information (KISTI), KR Hanyang University, KR Seattle Science Foundation, US 12 sites IN:1, JP: 2, TW: 1, VN: 2, PH: 2, CN: 1, KR: 2, US: 1 九州大学 UI プロジェクト Kyudai Taro,2007

  2. 2 HD-SCR: High Definition Streaming Combined Remote conference system Introduction *DVTS plays central part in our telemedicine activity. Advantage: High frame rate, DV quality image. Disadvantage: High bandwidth, NTSC dedicated. *Next generation conference system is desired. Hi quality HD image support (Low compression, High frame rate), NTSC/PAL compatibility, Multipoint connection (over 10), Easy preparation, Easy sound handling, Tele-Pointer: Visual collaborative pointing interface for teleconference 九州大学 UI プロジェクト Kyudai Taro,2007 4 HD-SCR: High Definition Streaming Combined Remote conference system HiDVTS: Impossible to connect multipoint. H.323 compatibles: There is an advantage of easy handling but they support hi-compressed image only. Streaming system: There are advantages of image quality, easy handling and preparation but it does not support remote conversation. Tele-Pointer : Good solution does not exist currently. Combine few systems to meet our requirements. 九州大学 UI プロジェクト Kyudai Taro,2007

  4. 7 HD-SCR: High Definition Streaming Combined Remote conference system Tele-Pointer specifications *Server-Client type commercial software. *Operates with Windows PC. *Accepts five cursors rendering at once. *Accepts twenty clients connections. *All clients can get cursor control authority. *The client software can be distributed. Tele-Pointer is developed for our purpose by INTEC Inc, Japan. This solution expects to use with other image transmitting solutions, like streaming system or DVTS. 九州大学 UI プロジェクト Kyudai Taro,2007 8 HD-SCR: High Definition Streaming Combined Remote conference system HD streaming system overview HD streaming system overview HiDVTS client Selected HD source H.323 client Local H.264 Hardware Encoder Medial image Digital Multi Switcher (MEDIAEDGE-LEB4) (IDK MSD-4403 ) H.264 compressed 1280* 720 60p (8M) with Forward Error Correction data (1.6M) 11Mbps/each HD-streaming server (MEDIAEDGE Server) VPN Router (L2TP/IPsec gateway) PC for HD stream receiving and Tele-Pointer Tele-Pointer Server HD streaming and Tele-Pointer data go through L2TP/IPsec Link 九州大学 UI プロジェクト Kyudai Taro,2007

  6. 11 HD-SCR: High Definition Streaming Combined Remote conference system Achievements of HD-SCR *Hi quality HD image :1280*720 60p H.264 8Mbps *NTSC/PAL compatibility: accepts both signal *Multipoint connection: up to 20 sites ? (One HD streaming server supports 200M streams in total.) *Easy preparation: one conference device and one PC *Easy sound handling: undertook by TV conference system *Tele-Pointer: realized by new software 九州大学 UI プロジェクト Kyudai Taro,2007 12 HD-SCR: High Definition Streaming Combined Remote conference system Challenges facing HD-SCR *Reduce time delay of HD stream: 2-4sec. *Investigate better way to transmit HD quality image from presentation providing site to TEMDEC. -HiDVTS: more sensitive to packet lost than DVTS. -H.323: quality depends on a terminal specification. -VLC media player: Long time delay *Gain experience of HD-SCR through this telemedicine activities. 九州大学 UI プロジェクト Kyudai Taro,2007
