AUDIO-BASED DATA LABEL TRANSMISSION SYSTEM AND METHOD Russian patent published in 2018 - IPC G10L15/30 G06F3/16 

FIELD: information technology.

SUBSTANCE: invention relates to means for transmitting information using data labels based on audio frequency. Method comprises compiling data in audio frequency in accordance with a pre-established rule or rules and linking parts, several parts or all of the data in the audio frequency with a fragment or fragments of previously compiled label information through the audio frequency processing equipment to generate related data in the audio frequency. Method then includes reading associated data in the audio frequency from the audio frequency processing equipment and outputting the associated data in the audio frequency in the form of sound waves through playback equipment in the audio frequency. Output sound waves are obtained from the playback equipment in the audio frequency through a microphone and the sound waves received through the microphone are converted into digital data in the audio frequency of a user terminal through a sound wave digitisation processor in the user terminal.

EFFECT: higher efficiency of information transfer.
