Abstract

Un método de decodificación de video llevado a cabo por un dispositivo de decodificación de video de acuerdo con el presente documento puede comprender los pasos de: adquirir información de imagen de un flujo de bits, en donde la información de imagen incluye un encabezado de imagen asociado con la imagen actual que incluye una pluralidad de segmentos; analizar, a partir del encabezado de imagen, al menos uno de un primer indicador que indique si información necesaria para una operación de inter predicción para un proceso de decodificación está presente en el encabezado de imagen, o un segundo indicador que indique si información necesaria para una operación de intra predicción para el proceso de decodificación está presente en el encabezado de imagen; generar muestras de predicción al llevar a cabo al menos una de intra predicción o inter predicción para los segmentos en la imagen actual sobre la base de al menos uno del primer indicador o el segundo indicador; y generar muestras reconstruidas sobre la base de las muestras de predicción.
