Skype is an attractive communication platform with two way audio and video communication. Unfortunately screen sharing is only available between two users, not in group calls. There are also performance trade offs when the same computer is screen scrapping and encoding audio-video for Skype. With this architecture, the quality of video may suffer. This means that, depending on multiple factors including computer loading, network congestion and Skype video compression, the streamed video may contain artifacts and the resulting frame rate may vary.

Epiphan customers can inject and stream video during a Skype call using Epiphan video grabbers user as shown in the diagram above.
