Abstract
A method and system capable of playing different audio signals in different nodes of a small environment. The system is comprised of a number of nodes, which may be rooms of a house or hotel, or offices of a business. Each node has at least one audio speaker. The system further comprises an audio signal distribution device, which is connected to the nodes and delivers audio signals to the nodes. The audio signal distribution device further comprises a storage device for storing the audio signals. At least one of the nodes has a control interface for selecting the audio signals to be transferred to the nodes. In this fashion, each node is capable of playing a different audio signal than any other node is playing concurrently.
