NewTek’s NDI solution is a really amazing actually suite of software designed to transport audio and video data over networks.
Note: I recommend a gigabit connection between the producers and consumers, as it easily saturates 100 MB/s with all settings max’d.

I’ve been using it a while:

• Screen recording
• Laptop screen streaming - Scan Converter on the laptop, Virtual Input on the desktop
• RICE Rally 2018 - Use OBS to create composites from several NDI sources

Software

Scan Converter

Share your computer screen, or a region of the screen
Each display on the computer comes as an individual source

Studio Monitor

A client to view sources on your network (or localhost)

Test Patterns

Generates a test pattern source

Virtual Input

Turns a source into a virtual webcam on your computer

Access Manager

• Yeah uhm not sure

Integration

Adobe Premiere Pro has NDI support,
VLC has NDI support,
OBS has NDI support,

ProPresenter 6 has support, but needs a costly license
