API for DM NVX® AV-over-IP Distribution Systems

Developer Microsite

DM NVX® AV-over-IP network encoders and decoders transport video, audio, and USB signals over standard Gigabit Ethernet. A range of devices across the lineup provides the flexibility to support up to ultra high-definition 4K video with 60 Hz framerates and 4:4:4 color sampling. With devices supporting Pixel Perfect Processing technology, a video signal is encoded, transported across the network, and decoded to achieve imperceptible end-to-end latency of less than one frame.

DM NVX technology also supports the extension of USB signals, which can be switched and routed alongside the AV signal or separately via a control system. This allows a USB mouse, keyboard, or other peripheral device to be connected to a remote endpoint and routed to a computer or other host at the local endpoint. The platform also leverages AES67 and natively supports DM NAX® Audio-over-IP networking to discretely extract and route audio signals to a broad range of AES67 compatible devices.

This documentation describes the API for the DM NVX series of AV-over IP distribution systems. The API allows programmers to modify device settings and view device status using API calls.

The DM NVX API binds to the DM NVX device as a new transport interface (much like a direct transport interface or a serial join interface). The API layer provides a translation from the DM NVX device. Web server requests are stateless, and all stateful information is maintained between the DM NVX API layer and device settings. JSON interfaces called CresNext objects are used as the messaging protocol to send and receive data via the API.
