Abstract:
(EN) The low power information providing method for an audio frequency band audio signal of the present invention comprises the steps in which: (a) an encoding device receives an input signal, classifies the input signal into an audio signal and a video signal, analyzes components of the classified audio signal, and generates first and second key signals; (b) the encoding device encrypts the generated first and second key signals by using a quantization variable, checks whether the first and second key signals are inserted into a corresponding time slot without deterioration, and encodes the classified audio signal in an audio frequency band; (c) a broadcasting device receives the encoded audio signal, and performs streaming transmission; (d) a receiving device receives the transmitted encoded audio signal, and converts the same to an analog signal to output the analog signal; (e) a mobile device receives the converted analog signal, performs quantization by controlling a quantization variable included in an embedded detection algorithm, detects the first and second key signals, and outputs the same; and (f) a server receives the detected first and second key signals through a wireless communication network, extracts information matching the key signals out of information already stored therein, and transmits the extracted information to the mobile device.
(FR) Le procédé de fourniture d'informations de faible puissance destiné à un signal audio en bande de fréquences audio selon la présente invention comprend les étapes suivantes : (a) un dispositif de codage reçoit un signal d'entrée, classe le signal d'entrée en tant que signal audio et que signal vidéo, analyse des composantes du signal audio classé, et génère des premier et second signaux clés; (b) le dispositif de codage chiffre les premier et second signaux clés générés en utilisant une variable de quantification, vérifie si les premier et second signaux clés sont insérés dans un créneau temporel correspondant sans détérioration, et code le signal audio classé dans une bande de fréquences audio; (c) un dispositif de diffusion reçoit le signal audio codé et effectue une transmission en continu; (d) un dispositif de réception reçoit le signal audio codé transmis et convertit celui-ci en un signal analogique pour fournir en sortie le signal analogique; (e) un dispositif mobile reçoit le signal analogique converti, effectue une quantification par commande d'une variable de quantification comprise dans un algorithme de détection intégré, détecte les premier et second signaux clés, et les fournit en sortie; et (f) un serveur reçoit les premier et second signaux clés détectés par l'intermédiaire d'un réseau de communication sans fil, extrait des informations correspondant aux signaux clés parmi les informations déjà stockées dans ceux-ci, et transmet les informations extraites au dispositif mobile.
(KO) 본 발명의 가청 주파수 대역 오디오 신호의 저전력용 정보 제공 방법은 (a) 인코딩 장치가 입력 신호를 인가받아 오디오 신호 및 비디오 신호로 분류하고, 분류된 오디오 신호의 성분을 분석하여 제1 및 제2 키 신호를 생성하는 단계; (b) 인코딩 장치가 양자화 변수를 이용하여 생성된 제1 및 제2 키 신호를 암호화하고, 해당 시간대에 해당 제1 및 제2 키 신호가 열화 없이 삽입되었는지 점검하여 가청 주파수 대역에서 분류된 오디오 신호를 인코딩하는 단계;(c) 방송 장치가 인코딩된 오디오 신호를 인가받아 스트리밍 전송하는 단계; (d) 수신 장치가 전송된 인코딩된 오디오 신호를 인가받아 아날로그 신호로 변환하여 출력하는 단계; (e) 모바일 기기가 변환된 아날로그 신호를 인가받아 내장된 검출 알고리즘에 포함된 양자화 변수값을 조절하여 양자화를 진행하여 제1 및 제2 키 신호를 검출하여 출력하는 단계; 및 (f) 서버가 무선 통신망을 통하여 검출된 제1 및 제2 키 신호를 인가받아 기 저장되어 있는 정보 중에서 매칭되는 정보를 추출하여 모바일 기기로 전송하는 단계;를 포함하는 것을 특징으로 한다.
