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.
