Abstract

são apresentadas técnicas de codificação por entropia para compressão de fluxo de exibição (dsc). em um aspecto, um método de codificação por entropia de dados de vídeo inclui particionar um bloco de dados de vídeo em uma pluralidade de grupos de amostras com base, pelo menos em parte, em um modo de codificação do bloco. o método inclui adicionalmente codificar por entropia o bloco através da realização de um salto grupo a grupo em pelo menos um dentre os grupos em resposta a todas dentre as amostras no pelo menos um grupo sendo igual a um valor pré-determinado.
