Abstract

Un método de decodificación de video llevado a cabo por un aparato de decodificación de video, de acuerdo con el presente documento, comprende: analizar información de número sobre el número de segmentos cuyas alturas se señalicen explícitamente en un mosaico de una imagen actual de un flujo de bits; analizar sintácticamente la información de altura sobre las alturas de los segmentos cuyas alturas se señalicen explícitamente desde el flujo de bits con base en la información de número; derivar el número de segmentos en el mosaico con base en la información de número y la información de altura; y decodificar la imagen actual en función de los segmentos en el mosaico, en donde la información de altura incluye el mismo número de elementos de sintaxis que un valor de la información de número, y en función de que el valor de la información de número sea n, las alturas de un 0-ésimo segmento a un n-1-ésimo segmento en el mosaico se pueden derivar en función de los elementos de sintaxis.
