Abstract

trata-se de diversas inovações que facilitam o uso de modos de previsão intrafiguração como modo de previsão de paleta, modo de cópia intrabloco, modo de cópia intralinha e modo de cópia intracoluna por um codificador ou decodificador quando o processamento paralelo em frente de onda ("wpp") estiver habilitado. por exemplo, para um modo de conversão em código/decodificação de paleta, um codificador ou decodificador prevê uma paleta para uma unidade inicial em uma fileira de wpp atual de uma figuração com o uso de dados da paleta anterior provenientes de uma unidade anterior em uma fileira de wpp anterior da figuração. ou, como outro exemplo, para um modo intracópia (por exemplo, modo de cópia intrabloco, modo de cópia intracoluna, modo de cópia intralinha), um codificador impõe uma ou mais restrições atribuíveis ao wpp, ou um decodificador recebe e decodifica dados codificados que satisfazem uma ou mais restrições atribuíveis ao wpp.
