Abstract

Se proporciona una unidad de ocultamiento de error (1402-1045) el método, y programa de computadora para proporcionar una información de audio de ocultamiento de error (1407) para ocultar una pérdida de una trama de audio en una información de audio codificada. En una modalidad, la unidad de ocultamiento de error es configurada para proporcionar una información de audio de ocultamiento de error (1407) usando un ocultamiento de dominio de frecuencia sobre la base de una trama de audio decodificada apropiadamente precedente a una trama de audio perdida. La unidad de ocultamiento de error es configurada para desaparecer (920) una trama de audio ocultada de acuerdo a factores de amortiguamiento diferentes (1403a-1404g) para bandas de frecuencia diferentes (1403a-1403 g).
MX2018010754A 2016-03-07 2017-03-03 Unidad de ocultamiento de error, decodificador de audio y método relacionado y programa de computadora que desaparece una trama de audio ocultada de acuerdo con factores de amortiguamiento diferentes para bandas de frecuencia diferentes. MX2018010754A (es)
