DIGITALES O UNA COMBINACIÓN DE AMBASDIGITAL OR A COMBINATION OF BOTH
OBJETO DE LA INVENCIÓNOBJECT OF THE INVENTION
La presente invención, tal y como se expresa en el enunciado de esta memoria descriptiva, se refiere a un método de control y procesado de señales analógicas, digitales o una combinación de ambas, cuya finalidad es facilitar nuevos procedimientos de tratamiento de señales, permitiendo controlar, limitar, restituir, separar y en definitiva efectuar cualquier tipo de tratamiento sobre una información que se extrae de la correspondiente señal y que es relativa a la complejidad de ésta, ya se trate de una señal analógica, o un flujo "stream" digital de información. La complejidad que se ha mencionado se refiere al grado de dificultad que presentan determinados componentes de la señal para ser transducidos . Con el método de la invención se permite de una forma novedosa obtener en la entrada del correspondiente terminal de recepción una señal adaptada bien a criterios estéticos, personalizados, tecnológicos, capacidades de los elementos humanos y técnicos que intervienen en la señal desde su generación hasta su recepción u otros requerimientos.The present invention, as expressed in the statement of this specification, refers to a method of control and processing of analog, digital signals or a combination of both, whose purpose is to facilitate new signal processing procedures, allowing control , limit, restore, separate and ultimately perform any type of treatment on information that is extracted from the corresponding signal and that is relative to the complexity of it, whether it is an analog signal, or a digital stream of information. The complexity that has been mentioned refers to the degree of difficulty that certain components of the signal present to be transduced. With the method of the invention it is allowed in a novel way to obtain at the entrance of the corresponding reception terminal a signal adapted well to aesthetic, personalized, technological criteria, capabilities of the human and technical elements that intervene in the signal from its generation to its generation Reception or other requirements.
ANTECEDENTES DE LA INVENCIÓN Son conocidos los sistemas donde una señal a tratar procede de una fuente y se lleva a un equipo electrónico tal como una cadena de sonido, vídeo, sistema de telecomunicación u otro para llegar a un terminal de recepción tal como un altavoz, pantalla de vídeo u otro aplicable a uno o más usuarios; de manera que dicha señal pasa por varias transducciones en su recorrido.BACKGROUND OF THE INVENTION Systems are known where a signal to be processed comes from a source and is carried to an electronic equipment such as a sound chain, video, telecommunication system or other to reach a reception terminal such as a speaker, video screen or other applicable to one or more users; so that said signal goes through several transductions in its path.
Hasta ahora, la complejidad contenida en la señal y/o la complejidad resultante del comportamiento
transductivo, es una función directa de la capacidad y comportamiento de cada sistema en su propia naturaleza, es decir, la resolución del transductor o transductores utilizados determina la complejidad posible en la salida. La mayoría de las técnicas de proceso digital o analógico, utilizadas para el tratamiento de la señal portadora de información formalizada resultado de una transducción, afectan a la complejidad en la misma medida que afectan al resto de la señal, y no en función de la complejidad misma.Until now, the complexity contained in the signal and / or the complexity resulting from the behavior transductive, is a direct function of the capacity and behavior of each system in its own nature, that is, the resolution of the transducer or transducers used determines the possible complexity in the output. Most of the digital or analogical processing techniques, used for the treatment of the formalized information carrying signal resulting from a transduction, affect the complexity to the same extent that they affect the rest of the signal, and not depending on the complexity same.
La complejidad en los sistemas convencionales de procesado de información no es un factor controlable, ya que los procesos actualmente en uso persiguen otros fines tales como el control espectral o dinámico, empleándose habitualmente tratamientos de señal tales como la ecualización, que maneja el contenido espectral de forma independiente a la complejidad misma, la compresión que reduce o destruye la complejidad transitoria sin afectar a cualquier otro tipo de complejidad, o la compresión multicanal que actúa de manera análoga a la compresión monocanal respecto de la complejidad de la señal.The complexity in conventional information processing systems is not a controllable factor, since the processes currently in use pursue other purposes such as spectral or dynamic control, usually using signal treatments such as equalization, which handles the spectral content of independently of the complexity itself, the compression that reduces or destroys the transient complexity without affecting any other type of complexity, or the multi-channel compression that acts analogously to the single-channel compression with respect to the complexity of the signal.
No conocemos en el estado actual de la técnica ningún método de control y procesado de señales que extraiga de la señal a tratar una información relativa a su complejidad, tal y como lo hace el método de la presente invención.We do not know in the current state of the art any method of control and signal processing that extracts information related to its complexity from the signal to be treated, as does the method of the present invention.
