The next generation of wireless networks will become the dominant means for video content delivery, leveraging rapidly expanding cellular and local area network infrastructure. We believe that video networks at every time-scale and layer should operate and adapt with respect to perceptual distortions in the video stream.

A team of researchers in the Department of Electrical and Computer Engineering at The Unversity of Texas at Austin (UT ECE) led by Prof. Andrea Alù has built the first-ever circulator for sound. The team’s experiments successfully prove that the fundamental symmetry with which acoustic waves travel through air between two points in space (“if you can hear, you can also be heard”) can be broken by a compact and simple device.
