This device enables the connection of a computer via USB to an AVB data network. AVB (Audio Video Bridge) is a digital network protocol for transporting time-sensitive data over Ethernet. It is an industry-standard protocol used in multimedia production to send audio, video, and other data over a network. ÒNormalÓ TCP/IP communication can also take place via the same network.
