Abstract

são fornecidos sistemas e métodos para codificação por entropia de dados de vídeo. uma pluralidade de amostras de um bloco de dados de vídeo é particionada em um ou mais grupos de amostras, com base em um modo de codificação do bloco e um formato de imagem de subamostragem de croma das amostras. a codificação por entropia é realizada no bloco por meio da realização de uma omissão de grupo em pelo menos um dentre os um ou mais grupos em resposta a todas as amostras no pelo menos um grupo terem um valor igual a um valor predeterminado, em que a omissão de grupo compreende evitar a codificação das amostras associadas ao pelo menos um grupo.
