3D videoconferencing system using spatial scalability

An implementation of a real-time 3D videoconferencing system using the currently available technology is presented. This approach is based on the side by side spatial compression of the stereoscopic images. The encoder and the decoder have been implemented in a standard personal computer and a conventional 3D compatible TV has been used to present the frames. Moreover, the users without 3D technology can use the system because 2D compatibility mode has been implemented in the decoder. The performance results show that a conventional computer can be used for encoding/decoding audio and video streams and the delay in the transmission is lower than 200 ms.
