    AV over IP

    The transport of audio, video, and control signals between encoders and decoders over an Ethernet network.

    What is AV over IP?

    AV over IP distributes audio and video using network switches instead of a fixed-input matrix switcher. Sources connect to encoders, displays connect to decoders, and authorized routes are selected through control software. The approach can scale well across divisible rooms, campuses, digital signage systems, and hospitality venues because endpoints can be added where the network has capacity. The design must match the application. Codec choice determines image quality, latency, and bandwidth. The network must support the required port speed, switching capacity, multicast configuration, quality of service, and sometimes redundant paths. HDCP, control, USB extension, audio breakaway, and device discovery also require coordination. The structured cabling scope should identify endpoint locations, cable category or fiber requirements, rack space, power, labeling, and certification. AV over IP can simplify expansion, but it transfers significant responsibility to network design and commissioning.

    Frequently asked questions

    No. AV over IP is a signal-transport architecture. A conferencing platform can use it, but conferencing also includes cameras, microphones, processing, control, and meeting software.

    It scales across many displays and sources using standard network switches and cabling, rather than fixed matrix switchers.

    Many systems use a dedicated or carefully segmented network with multicast support, because video streams can use a lot of bandwidth.
