以Windows Mobile 5為平台的視訊會議設計

Abstract

隨著手持裝置如Pocket PC、SmartPhone等逐漸普及化，以及微軟對Windows Mobile平台提供程式設計師豐富的API，因此開發有關行動裝置的程式如雨後春筍般湧現。其中能夠進行視訊VOIP的軟體如視訊會議程式，更加能發揮手持裝置的行動特性，並使我們的視訊會議能夠走到哪看到哪的便利性。 本論文便是以實作為主，以微軟所提供的Windows Moible 5 SDK配合Visual Studio 2005來開發手持裝置的視訊會議程式，另外也考慮到與一般PC的共通性，也額外開發以Windows XP為平台的視訊會議程式來跟手持裝置程式互通。除此之外，在我們的視訊會議架構，使用以一台PC為主的Transcoding Server來做未來的速率控制以及增強會議功能(如人臉辨識)用的伺服器。 本手持裝置用的視訊會議程式開發，也替業界提供一個在Windows Mobile 5平台上的視訊程式雛形。

As the hand-held device , such as Pocket PC or Smartphone , is popularized gradually, and Microsoft offers programmer abundant API on Windows Mobile platform, developing the application about action device emerges. The program that implements VOIP function like the video conference on the hand-held device, can bring the mobility into full play, making the convenience of the video conference to go where and see where. The goal of the thesis is to implement, and we use Microsoft Visual Studio 2005 and Microsoft Windows Mobile 5 SDK as the developing the video conference tools. In addition, considering the compatibility with general PC, we also develop the video conference application based on Windows XP platform to communicate with the program on the hand-held device. Besides, in the architecture of the video conference program, we use the Transcoding Server on the PC to implement the rate control function and the face detection in the future. The video conference program on the hand-held device also offers the prototype of this application on the Windows Mobile 5 platform to the enterprise.
