Inside Art-Net and sACN

Written with practicality in mind, Light Bytes provides a much needed technical reference on Art-Net and sACN. Starting with a networking primer, it moves onto the detailed packet structures and definitions used in each protocol. Following the theoretical groundwork, readers are guided through the problems that are often encountered in real-world applications, with tips on how to avoid them. The book strives for a balanced approach, comparing and contrasting Art-Net and sACN, while explaining how each protocol is evolving to meet the needs of a changing marketplace. There is a handy chapter on freely available software diagnostics tools, along with useful code examples for both Art-Net and sACN developers.
