Abstract

1/1 resumo "paralelização amigável de candidatos de junção para codificação de vídeo". esta invenção apresenta métodos e sistemas para 5 codificação de vídeo em modo de junção de um processo de predição de vetor de movimento. um método de codificação de dados de vídeo pode determinar um conjunto de candidato de junção para uma unidade de predição atual de uma unidade de codificação atual, em que o conjunto de candidato de junção 10 é determinado sem comparar informação de movimento de um candidato de junção no conjunto de candidato de junção com a informação de movimento de qualquer outra unidade de predição, e realizar um processo de predição de vetor de movimento de junção para a unidade de predição atual usando 15 o conjunto de candidato de junção. o método pode adicionalmente compreender excluir candidatos de junção do conjunto de candidato de junção que estão dentro de outra unidade de predição da unidade de codificação atual.
