Practical Applications of Digital Media Networking - ProLight + Sound Frankfurt
Download as PPT, PDF2 likes783 views
The document discusses digital audio networking technologies. It provides a history of digital audio networking standards including AES3, MADI, AES50, and AES67. It describes early protocols like CobraNet and EtherSound and more recent protocols like Dante and AVB. It compares analog multicore cabling to digital audio over Ethernet solutions, noting benefits like lower cost, easier routing, and longer maximum distances for digital networks.
