A remote user interface transmits a digital media request through a first communication link to a media management control which is coupled by a second communication link to a digital audio-visual playback device for selecting and playing a stored digital media by the playback device. The media management control executes a set of rules applicable to each playback device in determining whether or not a user request will be accepted or rejected for play on a particular playback device.

A remote user interface transmits a digital media request through a communication link to a control which is coupled to a digital audio-visual playback device for selecting and playing a stored digital media by the playback device. The control receives the digital media request and transmits digital media selection and/or the selected digital media content directly to a selected playback device or indirectly to the selected playback device through a playback device server.

The communication between the control and the playback device can be through a global communication network. Show less

A wireless audio transmission apparatus and method for coupling audio players to audio receivers for broadcast of audio signals stored in and processed by the audio player. A housing carrying operative circuitry is electrically connected by a multiconductor cable to an audio player for receiving stereo channel signals. Band pass filters couple the stereo signal and signal ground conductors in the cable to the stereo encoder in the housing. The filtered stereo signals are received by a stereo… Show more

A wireless audio transmission apparatus and method for coupling audio players to audio receivers for broadcast of audio signals stored in and processed by the audio player. A housing carrying operative circuitry is electrically connected by a multiconductor cable to an audio player for receiving stereo channel signals. Band pass filters couple the stereo signal and signal ground conductors in the cable to the stereo encoder in the housing. The filtered stereo signals are received by a stereo encoder in the housing and modulated onto a radio frequency carrier signal. A transmitter coupled to an antenna carried in the cable wirelessly transmits the carrier signal and the audio signals to a remote radio frequency receiver for demodulation and broadcast of the audio signals. Preferably, the carrier signal is an FM radio frequency signal. The carrier signal is optionally selectable from a plurality of different carrier signal frequencies. In an optional aspect, the operative circuitry in the housing may be embedded directly in an audio player. Show less

A high frequency signal transmission apparatus includes a transmitter for transmitting received signals from a signal source as a modulated signal on a high frequency 900 MHz carrier to a remote receiver. The remote receiver converts the high frequency carrier in at least one conversion step to a lower frequency carrier signal. The lower frequency carrier signal carrying the modulated signal is then converted to another carrier signal and retransmitted as a modulated second signal to another… Show more

A high frequency signal transmission apparatus includes a transmitter for transmitting received signals from a signal source as a modulated signal on a high frequency 900 MHz carrier to a remote receiver. The remote receiver converts the high frequency carrier in at least one conversion step to a lower frequency carrier signal. The lower frequency carrier signal carrying the modulated signal is then converted to another carrier signal and retransmitted as a modulated second signal to another remote receiver capable of demodulating the signal and broadcasting the audio sounds or video images. The oscillators in the transmitter and receiver are selectable to operate at discrete frequencies. Automatic fine tuning control is provided in the receiver to accommodate drift of the oscillator in the receiver. A recorder is coupled to the receiver for temporarily storing a demodulated first signal from the transmitter and then outputting the stored signals to a second transmitter for retransmission to a remote output device.
