Is the impossible possible??

I'm researching whether it is possible to achieve the following setup:

Central location within the house to store freesat receiver, dvd/blue ray player, VHS, broadband router, music storage. To then connect all these to a single streamer and transmit wirelessly to tv in lounge and bedroom. Finally to also be able to wirelessly connect the laptop would be a bonus.

The only item I have of the above is the broadband router (usual free D Link box when signing up with Madasafish), the rest is obselete and will be replaced with whatever solution (if it exists). The TVs will be wall mounted and already have electrical and coaxial sockets located mid height on the walls and are temporarily covered over with paintings.

If the above is possible can you transmit HD sound and audio to those devices that can handle the information without loss of quality?

Apologies if this comes across as clueless but having searched numerous places and forums I am now on the brink of falling into a vicious circle of confusion.

Cheers
