Abstract
Un aparato para codificar una señal multicanal que comprende por lo menos dos canales, comprende: un convertidor tiempo-espectral (1000) para convertir secuencias de bloques de valores de muestreo de los por lo menos dos canales en una representación en el dominio de las frecuencias que tiene secuencias de bloques de valores espectrales para los por lo menos dos canales; un procesador multicanal (1010) para aplicar un procesamiento multicanal conjunto a las secuencias de bloques de valores espectrales para obtener por lo menos una secuencia resultado de bloques de valores espectrales que comprende información relacionada con los por lo menos dos canales; un convertidor espectral-tiempo (1040) para codificar la secuencia de salida de bloques de valores de muestreo de manera de obtener una señal multicanal codificada (1510), en donde el codificador núcleo (1040) está configurado para operar de acuerdo con un primer control de tramas de manera de proveer una secuencia de tramas, en donde una trama esta delimitada por un límite de inicio de trama (1901) y por un límite de fin de trama (1902), en el donde el convertidor tiempo-espectral (1000) o el convertidor tiempo espectral (1030) están configurados para operar de acuerdo con un segundo control de tramas que está sincronizado con el primer control de tramas, en donde el límite de inicio de trama (1901) o el límite de fin de trama (1902) de cada trama de la secuencia de tramas se halla en una relación predeterminada con respecto a un instante de inicio o con respecto a un instante final de un porción superpuesta de una ventana utilizada por el convertidor tiempo-espectral (1000) para cada bloque de la secuencia de bloques de valores de muestreo o utilizado por el convertidor tiempo espectral (1030) para cada bloque de la secuencia de salida de bloques de valores de muestreo.An apparatus for encoding a multichannel signal comprising at least two channels, comprises: a time-spectral converter (1000) for converting block sequences of sampling values of the at least two channels into a representation in the frequency domain having block sequences of spectral values for at least two channels; a multichannel processor (1010) for applying a multichannel processing together to the sequences of spectral value blocks to obtain at least one sequence resulting from spectral value blocks comprising information related to the at least two channels; a spectral-time converter (1040) for encoding the block output sequence of sampling values so as to obtain an encoded multichannel signal (1510), wherein the core encoder (1040) is configured to operate according to a first control of frames in order to provide a sequence of frames, where a frame is delimited by a frame start limit (1901) and by a frame end limit (1902), in which the time-spectral converter (1000) or the spectral time converter (1030) is configured to operate according to a second frame control that is synchronized with the first frame control, where the frame start limit (1901) or the frame end limit (1902 ) of each frame of the frame sequence is in a predetermined relationship with respect to a start instant or with respect to a final instant of a superimposed portion of a window used by the time-spectral converter (1000 ) for each block of the sequence of blocks of sampling values or used by the spectral time converter (1030) for each block of the sequence of output of blocks of sampling values.
