Abstract

Se proporciona un método de procesamiento de video que incluye realizar una conversión entre un video que comprende una pluralidad de imágenes, cada una comprendiendo al menos un segmento, y un flujo de bits del video, en donde el flujo de bits se ajusta a una regla de formato, en donde la regla de formato especifica incluir un primer campo indicativo de la presencia de un segundo campo que identifica un índice máximo para una imagen de referencia utilizada para codificar un segmento en base a una condición; en donde la condición puede ser representada como una expresión lógica “A & (B || C)”, en la que: A indica que un primer indicador que indica si la información de lista de imágenes de referencia está incluida en una estructura de sintaxis de cabecera de imagen es igual a 1, o el tipo de unidad de capa de abstracción de red (NAL) no es igual a un tipo de actualización de decodificación instantánea (IDR), o un segundo indicador que indica si la información de lista de imágenes de referencia podría estar presente en las cabeceras de los segmentos con tipos de unidades IDR NAL es igual a 1, B indica que un tipo de segmento es igual a P o B, y un número de entradas de referencia en la lista de imágenes de referencia 0 es mayor que 1, C indica que el tipo de segmento es igual a B y un número de entradas de referencia en la lista de imágenes de referencia 1 es mayor que 1, y en donde “&” es la operación lógica “y” y “||” es la operación lógica “o”.
