Abstract

um método para decodificar dados de vídeo inclui receber um bloco de dados de vídeo, determinar um modo intra predição para o bloco de dados de vídeo, e determinar se utiliza ou não um modo de combinação de predição dependente de posição (pdpc) para decodificar o bloco de dados de vídeo com base pelo menos no modo de intra predição determinado. o método também pode incluir receber um elemento de sintaxe associado a uma transformada primária ou uma transformada secundária usada para um bloco de dados de vídeo, determinando o uso de uma ou mais ferramentas de codificação de vídeo com base em um valor do elemento de sintaxe, a uma ou mais ferramentas de codificação de vídeo sendo técnicas de codificação de vídeo diferentes da transformada primária ou transformada secundária, e aplicando a uma ou mais ferramentas de codificação ao bloco de dados de vídeo com base no uso determinado.
