Many things do not work in legacy video conferencing. In previous years, the costs of computing for encoding and decoding in video conferencing were high. Hence, groups of people gathered in a room to share a video conferencing system. They sat around a conference table with a video camera and a screen and were connected to a similarly equipped remote conference room. The room system camera was typically set to capture everyone in the room and the meeting participants in the same room frequently faced each other instead of the camera and receiving display, leaving remote participants feeling disconnected from the conversation. For reliable transmission in such legacy systems, expensive dedicated networks or quality of service enhanced bandwidth has to be used.
