Abstract:
1. A system for processing a broadcast signal including a plurality of different information broadcast channels, said system comprising: a means for receiving a transmitted frequency band into said system, the transmitted frequency band including a plurality of waveforms, each of said waveforms corresponding to a different one of said information broadcast channels; an analog to digital converter configured to convert said plurality of waveforms from an analog format to a digital format if said transmitted frequency band is received in an analog format, said analog to digital converter outputting digital information for each of said information broadcast channels; a storage device configured to store digital information representing each of said plurality of waveforms of said transmitted frequency band; a searching means for searching the entire received frequency band for pre-selected content; a selector configured to select multiple waveforms simultaneously from said plurality of waveforms of said frequency band stored in the storage for concurrently accessing information in selected information broadcast channels corresponding to each one of said multiple waveforms without using a separate tuner for each of said channels; a means for processing information corresponding to said information in said selected information broadcast channels retrieved from the storage; and a means for presenting said information to a user, wherein when a type of modulation used to modulate a desired baseband signal is known or surmised, then a modulated version of the baseband signal is synthesized and then be used as a template for searching the entire received frequency band for occurrences of the desired baseband signal.
