Abstract

Se describen dispositivos, sistemas y métodos para codificación de coeficiente en modo de salto de transformada. Un método de ejemplo para procesamiento de video incluye determinar, para codificar uno o más bloques de video en una región de video de datos de medios visuales en una representación de flujo de bits de los datos de medios visuales, una dimensión máxima permitida hasta la cual se permite codificar un bloque de video actual del uno o más bloques de video usando un modo de salto de transformada de modo que se representa un residuo de un error de predicción entre el bloque de video actual y un bloque de video de referencia en la representación de flujo de bits sin aplicar una transformada; e incluir un elemento de sintaxis indicativo de la dimensión máxima permitida en la representación de flujo de bits.
