Abstract

A method for programming a universal remote control comprises receiving a signal from a source remote control, determining characteristic information based on the signal, comparing the characteristic information to a database, determining a matching code set for the source remote control based on the comparing, and configuring the universal remote control to mimic control features of the source remote control based on the matching code set. Still other aspects and other features are also described herein.

Claims

1. A method for programming a universal remote control, comprising:

(a) receiving at least one signal from a source remote control;

(b) determining characteristic information based on said signal;

(c) comparing said characteristic information to a database of said universal remote control;

(d) determining a matching code set for said source remote control based on said comparison; and

(e) configuring said universal remote control to mimic control features of said source remote control based on said matching code set, wherein said determining in said (b) includes;

(1) identifying a timing sequence based on said signal;

(2) determining a plurality of repeating characteristics of said timing sequence;

(3) associating one type of repeating characteristic as a first bit type;

(4) associating a second type of repeating characteristic as a second bit type; and

(5) representing said timing sequence as a binary string comprised of said bit types.

2. The method of claim 1, wherein said (a) includes moving at least one of said source remote control and said universal remote control until a sufficiently strong signal is being received by said universal remote control.

3. The method of claim 2, further comprising triggering a signal to a user of said universal remote control that said signal is sufficiently strong.

4. The method of claim 1, wherein said signal includes redundant information, and wherein third type of repeating characteristic is a pattern of repetition of said redundant information.

5. The method of claim 1, wherein said signal includes redundant information, wherein said characteristic information includes a signal lag time, and wherein said signal lag time is a time between said redundant information.

6. The method of claim 1, further comprising:

(f) performing one or more troubleshooting techniques if no matching code set is determined at said (d).

7. The method of claim 1, further comprising:

(f) connecting to a network; and

(g) updating said database via said network.

8. The method of claim 1, wherein said matching code set is stored in said database of said universal remote control.

9. The method of claim 1, wherein said characteristic information includes a timing sequence of a series of “

on” and

“

off”

bursts.

10. The method of claim 9, wherein said characteristic information includes more than two mark-space timing pairs.

11. A method for programming a universal remote control, comprising:

(a) receiving at least one signal from a source remote control;

(b) determining characteristic information based on said signal, wherein said characteristic information is taken from the group consisting of;

a modulation type, a carrier frequency, a mark-space characteristic, a signal repetition characteristic and a signal lag time;

(c) comparing said characteristic information to a database of said universal remote control;

(d) determining a matching code set for said source remote control based on said comparison;

(e) configuring said universal remote control to mimic control features of said source remote control based on said matching code set; and

(f) performing one or more troubleshooting techniques if no matching code set is determined at said (d), wherein said performing further comprises;

(1) connecting to a remote computer;

(2) transmitting said characteristic information to said remote computer and thereby allowing said remote computer to find a matching code set; and

(3) receiving said matching code set from said remote computer.

12. The method of claim 11 wherein said modulation type is taken from the group consisting of:

constant carrier modulation (CCM), base band (BB) modulation, frequency shift keying (FSK) and complex frequency shift keying (C_FSK).

13. A computer readable medium for executing a computer method, comprising logic instructions that, if executed:

(a) receive at least one signal from a source remote control;

(b) determine characteristic information based on said signal, wherein said characteristic information is taken from the group consisting of;

a modulation type, a carrier frequency, a mark-space characteristic, a signal repetition characteristic and a signal lag time;

(c) compare said characteristic information to a local database;

(d) determine a matching code set for said source remote control based on said comparison;

(e) configure a universal remote control to mimic control features of said source remote control based on said matching code set;

(f) connect to a remote computer if no matching code set is determined at said (d);

(g) transmit said characteristic information to said remote computer, thereby allowing said remote computer to find a matching code set; and

(h) receive said matching code set from said remote computer.

14. The computer readable medium of claim 13, wherein said logic instructions include logic instructions that, if executed,

(1) identify a timing sequence based on said signal;

(2) determine said characteristic information by converting at least a portion of said timing sequence into a binary string.

15. The computer readable medium of claim 13, wherein said signal includes redundant information, and said logic instructions for determining characteristic information in (b) include logic instructions that, if executed, determine a pattern of repetition of said redundant information.

16. The computer readable medium of claim 15, wherein said signal lag time is a time between said redundant information.

17. The computer readable medium of claim 13, further comprising logic instructions that, if executed:

(f) connect to a network; and

(g) update said database via said network.

18. The computer readable medium of claim 13, wherein said carrier frequency of said signal is constant.

19. The computer readable medium of claim 13, wherein said mark-space characteristic is a timing sequence of a series of “

on” and

“

off”

bursts.

20. The computer readable medium of claim 13, wherein said modulation type is taken from the group consisting of:

constant carrier modulation (CCM), base band (BB) modulation, frequency shift keying (FSK) and complex frequency shift keying (C_FSK).

21. The computer readable medium of claim 13, wherein said signal includes redundant information, and wherein said signal repetition characteristic is a pattern of repetition of said redundant information.

22. The computer readable medium of claim 21, wherein said signal lag time is a time between said redundant information.
