Everything in my apartment is still wired together. I have a ton of HDMI cables connecting all my devices to my TV (blu ray player, gaming consoles, satellite box), and I have a 3.5mm jack connecting the speaker system to my audio source.
I know there are some advances in wireless tech for home entertainment. Video game controllers have been wireless since the 7th generation consoles. Bluetooth to connect speakers to audio devices exists. I’ve seen commercials on TV for cable TV that can stream wirelessly to the TV.
So how far off are we (or are we already there) to a point where you can have your TV and speakers be wirelessly connected to all your audio or video inputs, where you can stream movies (via satellite TV, or digital copies, or blu ray) to any TV in the house or where you can have audio streamed to speakers w/o connecting them with wires? My impression is we already have wireless speakers, but they are far more expensive than the traditional wired ones.
Does this tech already exist, if so is it affordable? Is there anything that can provide the quality of HDMI cables but does so wirelessly?
Even if wireless isn’t ready yet, can a powerline adapter kit be used in lieu of an HDMI cable? Can you send signals from a blu ray player in one room to a TV in a different part of the house via powerline adapter kits?
