Audinate will share its vision on how Dante and AES67/SMPTE ST 2110 can be used together in a modern broadcast workflow. Beginning with explanation of Dante integrations with open standards (both with and without Dante Domain Manager) will lead through audio needs such as rapid patching through the network, network security, Layer 3 traversal, and real-time fault monitoring. The presentation continues with practical structural network examples to optimize workgroup performance.
