Split ethernet signal from 2 devices into 1 port on router?

Hello, I have very little technical knowledge on this subject so would appreciate some advice in laymans language from the expert please!
Basically I have a router connected to my phone line at one end of my living room and a very long (probably 7metres) ethernet cable connected from the router extending to the other side of the room connected to the TV.
When I got my house the living room had wooden flooring and so I got a carpet laid and this went over the long ethernet cable so you can only see either end of the cable - 1 connected to the tv and 1 connected to the router.
I would now like to get a set top box but this would also need an ethernet connection so given I cant lift up the carpet to run another cable underneath it my options are:
Option A:  to have a cable connecting set top box and router above the carpet (the living room is not really well designed to have this well hidden away so I don't really like this option) or ideally:
Option B:  if I can get some sort of a splitter for the end where the TV is at with the current cable going into that being split into 2. I would then get 2 short ethernet cables to go from the splitter, 1 for the TV and 1 for the set top box. So the signal would still be coming passing down the same port from the router but being split into 2 devices at the other end.
I would like to know if I do this, will this work (ie will the TV and set top box have internet connectivity through the Ethernet cable) and are there any repercussions in this with regards to the speed as opposed to if they had their own dedicated cable as in option A?
Many thanks for your help.

    You only need a simple "switch" at the TV end of the cable. They can be picked up almost anywhere electronics are sold for as little as US$10. There are many brands and variants, but you only need one of the very simplest ones.
