Abstract

An integrated land mobile dispatch radio capable of accommodating both standard audio transmissions and video transmissions. The push-to-talk switch controls these activities. Video images can be stored and reviewed prior to transmission. Also, video transmissions can be interrupted to accommodate a current need to conduct an audio transmission.

Claims

1. A two-way dispatch radio communication unit, comprising:

A) radio transceiver means for transceiving dispatch communications;

B) microphone means operably coupled to the radio transceiver means for providing audible messages to the radio transceiver means to allow transmission of the audible messages;

C) video input means operably coupled to the radio transceiver means for providing video information to the radio transceiver means to allow transmission of the video information;

D) control means operably coupled to the radio transceiver means, for controlling operation of the radio transceiver means in at least a first and second discrete mode of operation, wherein;

i) in the first discrete mode of operation, the radio transceiver means transmits the audible messages; and

ii) in the second discrete mode of operation, the radio transceiver means transmits the video information;

E) push-to-talk switch means operably coupled to the control means, for selecting the first and second discrete modes of operation.

2. The two-way dispatch radio communication unit of claim 1 wherein the radio transceiver means, the microphone means, the video input means, and the control means are integrally housed together.

3. The two-way dispatch radio communication unit of claim 1, and further including:

F) speaker means operably coupled to the radio transceiver means for rendering received audio messages audible.

4. The two-way dispatch radio communication unit of claim 1, and further including:

F) video display means operably coupled to the video input means for displaying a video depiction provided by the video input means.

5. The two-way dispatch radio communication unit of claim 1, and further including:

F) display means operably coupled to the video input means and to the control means for selectively displaying;

i) radio operating information;

ii) a video depiction provided by the video input means.

6. The two-way dispatch radio communication unit of claim 1, and further including:

F) memory means operably coupled to the video input means for storing at least one video image.

7. The two-way dispatch radio communication unit of claim 6, and further including:

G) video display means operably coupled to the memory means for displaying the video image stored in the memory means.

8. The two-way dispatch radio communication unit of claim 7, wherein the memory means is operably coupled to the radio transceiver means, such that the radio transceiver means will selectively transmit the video image stored in the memory means.

9. The two-way dispatch radio communication unit of claim 8, such that the memory means selectively stores a video image received by the radio transceiver means.

10. The two-way dispatch radio communication unit of claim 9, wherein the video display means will further selectively display the video image received by the radio transceiver means.

11. A method of transmitting audio and video information, comprising the steps of:

A) monitoring a push-to-talk switch;

B) when the push-to-talk switch has been asserted in a first manner, transmitting audio information as input through a microphone;

C) when the push-to-talk switch has been asserted in a second manner, which said second manner is different from the first manner, transmitting video information as input through a video input device.

12. A method of processing audio and video information using a push-to-talk switch, comprising the steps of:

A) monitoring the push-to-talk switch;

B) when the push-to-talk switch has been asserted in a first manner, transmitting via radio audio information as input through a microphone;

C) when the push-to-talk switch has been asserted in a second manner, which said second manner is different from the first manner, storing a video image as input through a video input device.

13. A method of transmitting audio and video information, comprising the steps of:

A) monitoring a push-to-talk switch;

B) when the push-to-talk switch has been asserted in a first manner, transmitting via radio audio information as input through a microphone;

C) when the push-to-talk switch has been asserted in a second manner, which said second manner is different from the first manner, storing a video image as input through a video input device;

D) when the push-to-talk switch has been asserted in a third manner, which said third manner is at least different from the first manner, transmitting via RF the video image as previously stored.

14. A method of transmitting audio and video information, comprising the steps of:

A) monitoring a push-to-talk switch;

B) when the push-to-talk switch has been asserted in a first manner, transmitting via radio audio information as input through a microphone;

C) when the push-to-talk switch has been asserted in a second manner, which said second manner is different from the first manner, storing a video image as input through a video input device;

D) when the push-to-talk switch has been asserted in a third manner, which said third manner is at least different from the first manner, displaying the video image on a display device;

E) when the push-to-talk switch has been asserted in a fourth manner, which said fourth manner is at least different from the first manner, transmitting via RF the video image as previously stored.

15. A method of transmitting audio and video information, comprising the steps of:

A) monitoring a push-to-talk switch;

B) while the push-to-talk switch is asserted in a first manner, transmitting audio information as input through a microphone;

C) when the push-to-talk switch has been asserted in a second manner, which said second manner is different from the first manner, transmitting video information as input through a video input device unit until one of the following occurs;

i) the video information is completely transmitted;

ii) the push-to-talk switch is asserted in the first manner.

16. The method of claim 15, wherein step Cii includes the step of transmitting audio information as input through a microphone.

17. The method of claim 16, wherein step Cii further includes the step of resuming transmission of the video information when the push-to-talk switch is no longer asserted in the first manner.
