Abstract

"MéTODO E DISPOSITIVO PARA BUSCA E GRAVAçãO DE SINAIS DE MìDIA". A presente invenção se refere a um método e sistema para localização e gravação de seq³ências de sinal de tempo limitado (10, 20, 30, 40, 50, 60, 70, 80, 90) em canais de mídia que podem conter componentes de sinais indesejáveis (102, 103, 104, 105, 202, 204), por exemplo, a gravação de música em transmissões de rádio. Os sinais são continuamente bufferizados em uma memória. O usuário identifica um desejado material fonte. Fora desse material fonte desejado pode ser tomada uma seção como uma tecla de busca (100, 112, 400). O dispositivo pode também selecionar teclas de busca automaticamente. Se um segundo exemplo de tecla de busca (114, 200, 500, 510, 520) for detectado, as sequências de sinal que são conectadas em tempo às teclas de busca, são comparadas. As seq³ências de sinal que por comparação são substancialmente idênticas, são identificadas como pertencendo ao mesmo e desejado material fonte. A próxima etapa compreende uma iteração do procedimento acima e resulta em um segmento de maior e melhor qualidade do material fonte do que comparado ao segmento comum inicial."METHOD AND DEVICE FOR SEARCHING AND RECORDING MEDIA SIGNALS". The present invention relates to a method and system for locating and recording time-limited signal sequences (10, 20, 30, 40, 50, 60, 70, 80, 90) on media channels that may contain signal components. undesirable (102, 103, 104, 105, 202, 204), for example, recording music on radio broadcasts. Signals are continuously buffered in a memory. You identify a desired source material. Out of this desired source material a section can be taken as a search key (100, 112, 400). The device can also select search keys automatically. If a second example search key (114, 200, 500, 510, 520) is detected, the signal sequences that are connected in time to the search keys are compared. Signal sequences which by comparison are substantially identical are identified as belonging to the same desired source material. The next step comprises an iteration of the above procedure and results in a higher and better quality segment of the source material than compared to the initial common segment.
