Abstract

a presente invenção refere-se a uma facilidade para utilizar um dispositivo móvel para pesquisar conteúdo de vídeo que tira vantagem da capacidade de computação no dispositivo móvel para capturar entrada a partir de uma câmera e/ou de um microfone, extrair uma assinatura de áudio-vídeo da entrada em tempo real, e executar pesquisa progressiva. por extrair uma assinatura de áudio-vídeo de junção a partir da entrada em tempo real à medida que a entrada é recebida e enviar a assinatura para a nuvem para pesquisar conteúdo de vídeo similar através da indexação de áudio-vídeo em camada, a facilidade pode proporcionar resultados progressivos de vídeos candidatos para capturas de assinatura progressiva.
