Network configuration is a key consideration when deploying AV over IP, so if you're in the AV industry, you should probably familiarize yourself with the terms "Multicast"and "IGMP" sooner rather than later. Multicast is basically a group communication where a single stream of data is addressed to a group of destinations simultaneously rather than being sent to a single endpoint. Using multicast reduces the bandwidth requirements significantly, and provides an efficient met

The majority of the AV manufacturers have now jumped on the AV over IP bandwagon, Extron being the last of the big ones with the announcement of their NAV series last year. However, the design philosophy and price point varies widely between different manufacturers and technologies. How can certain solutions be purchased at a few hundred dollars, while others cost thousands? Some of this gap is explained by component quality, manufacturing country, and design complexity, but

Audio Networking is becoming increasingly popular. It started in the 90’s with CobraNet, but first took off with Audinate’s introduction of Dante in 2006. The key to Dante’s popularity is the ability to easily transmit and manage low-latency, high quality, multi-channel audio over standard Ethernet. A growing number of professional AV products not primarily designed for audio, including AV over IP solutions, do however not incorporate Dante support, they instead offer integra

The past years JPEG 2000 has become the de-facto codec standard for 1G AV over IP solutions. It has been used by AMX/Harman for years in several of their SVSi products, Crestron used it in their DM NVX, and a range of other manufacturers also ships AV over IP solutions based on JPEG 2000. Despite impressive growth of the 10G SDVoE ecosystem, there is still a need for lower bitrate solutions. Mixed feedback from customers, and concerns from IT departments, however, raises que
