Abstract

MÉTODO E APARELHO DE CODIFICAÇÃO DE IMAGEM MÓVEL A invenção refere-se a um método de codificação de imagem móvel para codificar uma imagem com chaveamento entre uma codificação de quadro e uma codificação de campo adaptavelmente em uma base de bloco por bloco, que inclui: determinar o número máximo de índices de referência para a codificação de campo para especificar campos os quais devem ser referidos no momento da codificação de campo, utilizar o número máximo de índices de referência para a codificação de quadro para especificar quadros os quais devem ser referidos no momento da codificação de quadro; e atribuir a campos os índices de referência para a codificação de campo para especificar campos os quais devem ser referidos no momento da codificação de campo, dentro de uma faixa do seu número máximo determinado, utilizando os índices de referência para a codificação de quadro para especificar quadros os quais devem ser referidos no momento da codificação de quadro.
