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

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
