Abstract

A selective call receiver comprises a receiver for receiving a signal, the signal comprising an address identifying the selective call receiver, a first information packet having a first information format, a second information packet having a second information format, and a control character. An output device presents the first information packet in a first output mode corresponding to the first information format in response to the control character, and the second information packet in a second output mode corresponding to the second information format in response to the address or a second control character.

Claims

1. A selective call receiver comprising:

receiver means for receiving a signal, the signal comprising;

an address identifying the selective call receiver;

an information packet associated with the address comprising a first information format and a second information format; and

a control character; and

presentation means for presenting the first information format in a first output mode in response to the address and the second information format in a second output mode in response to the control character.

2. The selective call receiver according to claim 1 wherein the first output mode comprises a numeric display.

3. The selective call receiver according to claim 1 wherein the second output mode comprises an alphanumeric display.

4. The selective call receiver according to claim 1 wherein the second output mode comprises an audible output.

5. The selective call receiver according to claim 1 wherein the second output mode comprises a graphics output.

6. A selective call receiver comprising:

receiver means for receiving a signal, the signal comprising;

an address identifying the selective call receiver;

a first information packet associated with the address comprising a first information format;

a second information packet associated with the address comprising a second information format; and

a first control character; and

presentation means for presenting the first information packet in a first output mode corresponding to the first information format in response to the first control character, and the second information packet in a second output mode corresponding to the second information format.

7. The selective call receiver according to claim 6 wherein the second information packet is presented in response to the address.

8. The selective call receiver according to claim 6 wherein the signal further comprises a second control signal, the second information packet being presented in response thereto.

9. The selective call receiver according to claim 6 wherein one of the first and second output modes comprises a numeric display.

10. The selective call receiver according to claim 9 wherein the other of the first and second output modes comprises an alphanumeric display.

11. The selective call receiver according to claim 9 wherein the other of the first and second output modes comprises an audible output.

12. The selective call receiver according to claim 6 wherein one of the first and second output modes comprises an alphanumeric display.

13. The selective call receiver according to claim 12 wherein the other of the first and second output modes comprises an audible output.

14. The selective call receiver according to claim 6 wherein the output mode comprises a graphics display.

15. A selective call receiver system comprising:

transmitter means for transmitting a signal;

receiver means for receiving the signal, the signal comprising;

an address identifying the selective call receiver;

a first information packet associated with the address comprising a first information format and a second information format; and

a first control character; and

presentation means for presenting the first information packet in a first output mode in response to the first control character.

16. The selective call receiver according to claim 15 wherein the first output mode comprises a numeric display.

17. The selective call receiver according to claim 15 wherein the first output mode comprises an alphanumeric display.

18. The selective call receiver according to claim 15 wherein the first output mode comprises an audible output.

19. The selective call receiver according to claim 15 wherein the output mode comprises a graphics display.

20. The selective call receiver system according to claim 15 wherein the signal further comprises a second information packet comprising a second information format, the presentation means presenting the second information packet in a second output mode corresponding to the second information format.

21. The selective call receiver according to claim 20 wherein the second information packet is presented in response to the address.

22. The selective call receiver according to claim 20 wherein the signal further comprises a second control signal, the second information packet being presented in response thereto.

23. The selective call receiver according to claim 20 wherein one of the first and second output modes comprises a numeric display.

24. The selective call receiver according to claim 23 wherein the other of the first and second output modes comprises an alphanumeric display.

25. The selective call receiver according to claim 23 wherein the other of the first and second output modes comprises an audible output.

26. The selective call receiver according to claim 20 wherein one of the first and second output modes comprises an alphanumeric display.

27. The selective call receiver according to claim 26 wherein the other of the first and second output modes comprises an audible output.

28. The selective call receiver according to claim 20 wherein the output mode comprises a graphics output.

29. In a selective call receiver, a method comprising the steps of:

receiving a signal having a single address, a control character, and first and second information packets; and

presenting information encoded from the first packet in a first output mode and from the second packet in a second output mode, the presention of the second packet in the second output mode being determined by the control character.
