I have FireTV stick in Samsung TV.
Also Samsung BlueRay Disc Player BD-D5700

Can I use the BD-D5700 as a Kodi Backend PVR hardware.

If not what hardware do I buy to connect to Cable Input feed.

Any guidance on setting up the PVR appreciated.
Bill

PS I have read : http://kodi.wiki/view/PVR

PPS I am confused with what actually IS a tvheadend server. Is it :
my BD-D5700 BlueRay reader?
my FireTV (a new App)
a separate NEW box I need to buy?

Tvheadend is basically a piece of software that functions as a pvr backend. The Tvheadend server is whatever device that software is running on, which could be a remote machine but is usually the same one kodi is running on.

Follow the wiki links: http://kodi.wiki/view/PVR => http://kodi.wiki/view/PVR_backend => http://kodi.wiki/view/Tvheadend_PVR => https://tvheadend.org/projects/tvheadend to understand the chain needed.

Again read http://kodi.wiki/view/PVR plus http://kodi.wiki/view/PVR_backend and note that Tvheadend is just one of many PVR backends avalable that is compatible witk Kodi.

http://kodi.wiki/view/PVR_backend list which PVR backends are compatible with Kodi (and your Samsung Blu-ray Disc Player is not listed there).

Suggest that you either buy a network-attached TV-tuners such as HDHomeRun (from SiliconDust) which is relativly easy for less computer savvy people going.

Second best alternative for less computer savvy people is buying a USB TV-tuner and run a Windows PC as a PVR backend with http://kodi.wiki/view/NextPVR
