Wireless transmitter

Bluetooth and Wi-Fi are the computer standards in wireless transmission.

But there are other means too.

Audioengine W1 Premium Wireless Audio Adapter

The Audioengine W1 is designed to connect your audio components wirelessly. Think of AW1 as a simple replacement for any RCA or 3.5" mini-jack cable to or from your iPod, Audioengine powered speakers, computer, TV, surround-sound receiver, game console, network music player - or any other product where you want to eliminate audio cables.

Audioengine D2

The D2 sends a 24bit/96KHz PCM stereo digital stream over-the-air in a "closed-system" Wi-Fi configuration. The system's proprietary RF technology ensures data integrity with no impact on existing routers or networks. The volume control on the D2 Sender is transmitted over an entirely separate channel so there is no impact on the digital audio stream.

One day I stumbled upon this post: A guy connected two audio devices by sending the S/PDIF over a wireless video transmitter.
