HD-SCR: High Definition Streaming Combined Remote conference system

九州大学UIプロジェクト Kyudai Taro,2007

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

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.

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.

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.
