How to implement Play to when streaming on Lg smart tv?

Question

Windows

The task is as follows:
There are several TVs to which you need to broadcast the stream over the network. Capture from computer and satellite.
Microsoft's new play to feature, which starts playback immediately without having to select an input, is completely incomprehensible how it is implemented.
Total: what software will allow you to select inputs and play video right away?

Answer 1

As far as I remember, Play to starts playback over the network = dig towards UPnP, DLNA, Miracast, Intel Widi, etc.
