Abstract
Se describen innovaciones para la señalización de estado de una memoria de imagen descodificada ("DPB") y listas de imagen de referencia ("RPLs"). En implementaciones ilustrativas, en lugar de depender del estado interno de un descodificador para manejar y actualizar DPB y RPLs, la información de estado sobre DPB y RPLs es explícitamente señalada. Esto permite a un descodificador determinar cual de las imágenes se espera que estén disponibles para referencia de la información de estado señalada. Por ejemplo, un codificador determina información de estado que identifica cual de las imágenes están disponibles para usarse como imágenes de referencia (opcionalmente considerando información de realimentación de un descodificador sobre cual de las imágenes esta disponible). El codificador establece elementos de sintaxis que representan la información de estado. Al hacer esto, el codificador establece información de identificación para una imagen de referencia de término largo ("LTRP"), en donde la información de identificación es un valor de bits mínimos significativos de cuenta de orden de imagen para la LTRB. El codificador entonces da salida a los elementos de sintaxis como parte de una corriente de bits.
