Abstract

The present invention provides a system including a portable device capable of displaying information from, and transmitting commands/controls to, a base station audio/video/data source via a local transceiver module. The audio/video/data source may be embodied in a portable or stationary satellite receiver/decoder, a local video source, or any similar device. The present invention allows for highly portable access to satellite information, without need for a satellite reception antenna associated with each portable device, and without disturbing the equipment in direct contact with the satellite as the portable devices are moved in a highly portable manner. Other embodiments of the present invention provide a distribution method and apparatus for use in theater or stadium settings.

Claims

1. An audio/video/data distribution system for distributing audio and video signals comprising:

a base unit comprising a plurality of integrated receiver/decoders, each of which directly receives the audio and video signals, converts the audio and video signals to local retransmission signals, and transmits the local retransmission signals; and

at least one remote terminal having communication circuitry that allows direct two-way communication with the base unit, the communication circuitry being connected to an element that receives the transmitted local retransmission signals, the remote terminal recovering the video signals from the received local retransmission signals, displaying the video signals on a display portion connected to the remote terminal, and playing the audio signals on a speaker connected to the remote terminal;

wherein the plurality of integrated receiver/decoders are individually addressable by the remote terminal, the remote terminal conveys commands to control the integrated receiver/decoders that are individually addressable by the remote terminal, and the remote terminal is provided with a coded identification, so that control signals from the remote terminal operate a selected one, as well as more than one, of the plurality of integrated receiver/decoders that are individually addressable by the remote terminal, and

wherein the plurality of receiver/decoders are individually addressable by a group of one or more remote terminals, and the control signals are prioritized, such that the control signals from preferred remote terminals take precedence over control signals from lower priority remote terminals.

2. The system of claim 1 wherein the base unit receives at least one additional video signal from a local audio/video/data source.

3. The system of claim 2 wherein the base unit receives at least some of the additional video signals from a camera.

4. The system of claim 1 wherein the remote terminal is a portable display unit and the portable display unit further comprises:

a display portion capable of displaying video signals;

an audio speaker for playing audio signals that accompany the video signals; and

a user control panel.

5. The system of claim 1 wherein at least one way of the two-way communication with the base unit is encrypted.

6. The system of claim 1 wherein the plurality of integrated receiver/decoders are individually addressable by a group of one or more remote terminals.

7. The system of claim 6 wherein the control signals are prioritized, such that the control signals from preferred remote terminals take precedence over control signals from lower priority remote terminals.

8. A portable display unit comprising:

a display portion capable of displaying video signals;

an audio speaker for playing audio signals that accompany the video signals;

a user control panel; and

communication circuitry that allows direct bi-directional RF communication with a remote base unit comprising a plurality of receiver/decoders that directly receive the video and audio signals from a satellite, encode the video and audio signals, and transmit the encoded audio and video signals to the portable display unit;

wherein the plurality of receiver/decoders are individually addressable by the portable display unit, and the portable display unit conveys commands to the remote base unit to operate a selected one, as well as more than one, of the plurality of receiver/decoders that are individually addressable by the portable display unit, and

wherein the plurality of receiver/decoders are individually addressable by a group of one or more portable display units, and the control signals are prioritized, such that the control signals from preferred portable display units take precedence over control signals from lower priority portable display units.

9. The portable display unit of claim 8 further comprising an audio/visual input device, wherein video data generated from the audio/visual input device is transmitted to the remote base unit.

10. The portable display unit of claim 8 wherein at least one direction of the bi-directional communication is encrypted.

11. A system comprising:

a ground-based receiver station comprising;

a plurality of integrated receiver/decoder units coupled to an antenna that directly receive audio and video signals from the antenna; and

a first omni-directional antenna that is coupled to the receiver/decoder units;

the receiver/decoder units converting the audio and video signals to RF signals and transmitting the RF signals via the first omni-directional antenna directly to a portable unit, which includes a recorder for recording the audio and video signals, and the receiver/decoder units including communication circuitry to receive communication transmitted from the portable unit to the receiver/decoder units via the first omni-directional antenna, wherein the plurality of receiver/decoder units are individually addressable by the portable unit, and the portable unit conveys commands to operate a selected one, as well as more than one, of the plurality of receiver/decoder units that are individually addressable by the portable unit, and

wherein the plurality of receiver/decoders are individually addressable by a group of one or more portable units, and the control signals are prioritized, such that the control signals from preferred portable units take precedence over control signals from lower priority portable units.

12. The system of claim 11, the portable unit further comprising:

a display portion capable of displaying video signals;

an audio speaker for playing audio signals that accompany the video signals;

a user control panel; and

circuitry that allows communication with the receiver/decoder unit.

13. The system of claim 11 wherein the circuitry and the control panel interact to allow a user to send commands to the receiver/decoder unit.

14. The system of claim 11 wherein a plurality of portable units are addressable by control signals from the receiver/decoder unit.

15. The system of claim 14 wherein the control signals are coded.

16. The system of claim 14 wherein the control signals are prioritized.

17. The system of claim 11, wherein the receiver/decoder unit further performs at least one of encrypting the RF signals or decrypting the communication from the portable unit.

18. The system of claim 11 wherein the plurality of receiver/decoder units are individually addressable by a group of one or more portable units.

19. The system of claim 18 wherein the control signals are prioritized, such that the control signals from preferred portable units take precedence over control signals from lower priority portable units.
