play DVD/Blueray over LAN

Firstly apologies if this is in the wrong place, but I struggled to find an answer.
Is it possible to watch DVDs/Bluerays that are playing on a panasonic player, over your LAN?

Setup:
Upstairs – TV and Blueray player, both connected to network via ethernet cable
Downstairs – Raspberry pi running OSMC connected to a different TV, again both connected to network via ethernet cable.

So can i play a DVD/Blueray upstairs but watch it downstairs?
Thank you
David
