Abstract

A mapping system for producing event identifying codes includes a plurality of video-audio-data (VAD) marker channels representative of a method for coding and/or encoding signals such as video and non-video signals. At least one of the VAD marker channels includes a plurality of sub-bands indicative of video transform components. The processing method is implemented at least in part by modulating the non-video signals, if any, onto the transform components, and by generating video transform components therefrom; generating video transform components from the video signals, if any; selecting desirable video transform components corresponding to the non-video signals and to the video signals, if any; and allocating the selected desirable video transform components to the sub-bands.

Claims

1. A mapping system for producing event identifying codes comprising:

one or more video-audio-data (VAD) marker channels representative of a method for processing video and non-video signals, as applicable;

at least one of said VAD marker channels including a plurality of sub-bands indicative of a plurality of video transform components;

said processing method being implemented at least in part by;

modulating said non-video signals, if any, onto one or more of said transform components and generating video transform components therefrom;

generating video transform components from said video signals, if any;

selecting desirable video transform components corresponding to said non-video signals and to said video signals, if any; and

allocating said selected desirable video transform components to said sub-bands.

2. The mapping system according to claim 1, wherein said video transform components correspond to Fourier transform frequencies.

3. The mapping system according to claim 1, wherein said processing method further includes the step of demultiplexing at least some of said video transform components into two or more separate video channels.

4. The mapping system according to claim 1, wherein said processing method further includes the step of separating at least some of said video transform components into two or more video sub-bands.

5. The mapping system according to claim 4, wherein said video sub-bands contain video transform components corresponding to fundamental and harmonic signals.

6. The mapping system according to claim 1, wherein said processing method further includes the step of selecting non-desirable components.

7. The mapping system according to claim 6, wherein said processing method further includes the step of assigning a different priority to said non-desirable components than a priority assigned to said desirable transform components.

8. A method for encoding signals using a mapping system to produce event identifying codes comprising:

identifying one or more marker channels representative of video and non-video signals;

dividing said one or more marker channels into a plurality of sub-bands indicative of a plurality of transform components;

modulating the non-video signals, if any, onto one or more of said transform components and generating video transform components therefrom;

generating transform components from the video signals, if any;

selecting desirable transform components; and

allocating said selected desirable transform components to said sub-bands.

9. The method according to claim 8, wherein said step of modulating the non-video signals, includes modulating onto one or more of Fourier transform components and generating video transform components therefrom.

10. The method according to claim 8, further including the step of separating at least some of said desirable transform components into two or more video sub-bands.

11. The method according to claim 8, wherein said step of selecting includes the step of selecting non-desirable transform components, and further including the step of assigning a different priority to said non-desirable components than a priority assigned to said desirable transform components.

12. A method for decoding signals using a mapping system to produce event identifying codes comprising:

14. The method according to claim 12, wherein said step of selecting includes the step of selecting non-desirable transform components.

15. The system according to claim 14, further including the step of assigning a different priority to said non-desirable components than a priority assigned to said desirable transform components.

16. A method for mapping digital signals comprising:

identifying one or more marker channels representative of video and non-video signals to be mapped;

dividing said one or more marker channels into a plurality of sub-bands indicative of a plurality of transform components;
