Considering its data-intensive representation and the best-effort nature of the Internet, delivery of stereoscopic omnidirectional videos (also known as the 360-degree video) requires advanced strategies to offer an enhanced VR experience. This work will propose a cost-efficient adaptive model to transmit the compressed stereoscopic omnidirectional videos. In this project, the well-known 3D perceptual concept of the human visual system will be studied for compression to achieve the best VR video quality performance.
