Abstract
são proporcionadas técnicas e sistemas para codificar e decodificar dados de vídeo. por exemplo, um método de codificar dados de vídeo inclui obter dados de vídeo em um codificador, e determinar para realizar predição intra-imagem nos dados de vídeo, usando predição de cópia intra-bloco, para gerar a pluralidade de imagens codificadas de vídeo. o método inclui também realizar a predição intra-imagem nos dados de vídeo usando a predição de cópia intra-bloco e, em resposta à determinação para realizar a predição intra-imagem nos dados de vídeo usando a predição de cópia intra-bloco, desabilitar pelo menos uma de predição dupla inter-imagem ou predição única inter-imagem para a pluralidade de imagens codificadas de vídeo. o método também inclui gerar a pluralidade de imagens codificadas de vídeo com base nos dados de vídeo recebidos de acordo com a predição de cópia intra-bloco realizada.
