METHOD AND APPARATUS FOR TRANSMITTING AUDIO AND NON-AUDIO INFORMATION WITH ERROR CORRECTION

摘要

A METHOD AND AN APPARATUS FOR PROVIDING DIGITAL QUALITY TRANSMISSION OF AUDIO AND NON-AUDIO INFORMATION USING LOW COST COMPONENTS AND ARRANGEMENT. THE PRESENT INVENTION PROVIDES FOR THE TRANSMISSION OF THE AUDIO AND NON-AUDIO TRANSMISSION BY FIRST CONVERTING THE DATA TO CONFORM TO THE CD STANDARD FORMAT AND CONDITIONING THE CONVERTED SIGNAL TO THEREBY GENERATE A CONDITIONED EFM SIGNAL. THE CONDITIONED EFM SIGNAL IS USED TO FREQUENCY MODULATE A CARRIER. BY CONVERTING THE AUDIO AND NON-AUDIO INFORMATION TO CONFORM TO THE CD STANDARD FORMAT, THE PRESENT METHOD PROVIDES A LOW COST MEANS OF TRANSMITTING THE DATA WITH ERROR DETECTION AND CORRECTION. ANOTHER ASPECT OF THE PRESENT INVENTION RELATES TO EMBEDDING THE NON-AUDIO INFORMATION IN THE SUBCODE BLOCK OF THE DATA FRAME ACCORDING TO THE CD STANDARD. THE NON-AUDIO INFORMATION MAY BE UNRELATED TO THE AUDIO INFORMATION, AND THE AUDIO AND NON-AUDIO INFORMATION MAY BE TRANSMITTED TO SEPARATE DEVICES. ANOTHER ASPECT OF THE PRESENT INVENTION RELATES TO CONTROLLING A VOLTAGE CONTROLLED OSCILLATOR IN RESPONSE TO THE FILL LEVEL OF A FILE BUFFER IN THE DECODER(320).
