Subject Re: Blue Sky Distance Collaboration System_Proposal Draft
Date Wed, 29 Aug 2007 01:06:22 GMT
When we launched /Blue Sky Distance Collaboration system /development, 
we according to some reasons like these:

   1. When we are discussing with somebody about a CAD drawing, if we
      can only watch video and hear voice of him/her, it's not enough.
      If we can are discuss how to use computer, it's much better if
      his/her computer screen is available. When we are having a lesson,
      it will be much vivid if teacher's slides, voice,video are
      available at the same time. When we are watching a football match
      in remote city, if we can watch it from various view point
      simultaneously, it becomes a much better enjoyment. This idea is
      use multiple scenes in distance communication, it is more than
      conference in which comprises only one video and its affiliated
      audio. So we use Collaboration instead(message communication is
      implement, file share and distribution is scheduled, towarding a
      flexible Collaboration platform ). In literature, this kind of
      application is called /Multi-object Multimedia
      Applications(MMAs)/. In our project, MMAs is used as basic
      component of visual and acoustic communication.
   2. For MMAs is used in our system, our player and recorder should
      have the capability to handle it. So, we developed a customed
      player(XPlayer for GNU/Linux, CWPlayer for Win32) and MMA capable

In this document(url is below) , there is also screenshot of our players:
