Abstract

Varias innovaciones facilitan el uso de modos de predicción intra-imagen, tales como modo de predicción de paleta, modo de copia intra bloque, modo de copia intra línea y modo de copia intra cadena por un codificador o descodificador cuando se habilita el procesamiento paralelo de onda frontal ("WPP"). Por ejemplo, para un modo de codificación/descodificación de paleta, un codificador o descodificador predice una paleta para una unidad inicial en una fila WPP actual para una imagen utilizando datos de paleta previos de una unidad previa en una fila WPP previa de la imagen. O bien, como otro ejemplo, para un modo intra copia (por ejemplo, un modo de copia intra bloque, modo de copia intra cadena, modo de copia intra línea), un codificador impone una o más restricciones atribuibles al WPP, o un codificador recibe y descodifica datos codificados que satisfacen una o más restricciones atribuibles al WPP.
