Abstract

a presente invenção se refere a um dispositivo para decodificação de dados de vídeo que inclui uma memória configurada para armazenar os dados de vídeo e um ou mais processadores configurados para receber uma fatia dos dados de vídeo, analisar um elemento de sintaxe da cópia intrablocos (ibc) para determinar que um modo ibc está habilitado para a fatia, analisar um elemento de sintaxe do tipo fatia associado à fatia para determinar que a fatia é uma fatia i e decodificar a fatia como uma fatia i decodificando todos os blocos da fatia usando modos de codificação intrapredição.
