Abstract
MÉTODO PARA DECODIFICAR INFORMAÇÕES DE MOVIMENTO, E MÉTODO PARA CODIFICAR INFORMAÇÕES DE MOVIMENTO Um método para decodificar informações de movimento inclui: identificar um tipo de informação de movimento de omissão não incluída em um fluxo contínuo de dados entre uma pluralidade de partes de informações de movimento usadas para decodificar um bloco atual que é previsto; obter as informações do movimento de omissão usando um método predeterminado; e decodificar o bloco atual com base na pluralidade de partes de informações de movimento, incluindo as informações de movimento de omissão obtidas.
