  • Half-duplex wireless audio communication system
    Patent number: 7046999
    Abstract: A wireless communication system that transmits content signals and remote control signals between a content retention and distribution system and a content reproduction terminal over a half-duplex channel such as an RF channel having the same frequency band. The wireless communication system includes a base station and a remote station. The base station formats and transmits the content signal over the half-duplex channel. The remote station receives the transmitted content signal and transfers the content signal to the content reproduction terminal. The content reproduction terminal has an input device to create remote control signals for the content retention and distribution system. The remote station receives the remote control signals from the content reproduction terminal and transmits the remote control signal to the base station for transfer to the content retention and distribution system on the half-duplex channel.
