Abstract

MÉTODO DE CODIFICAÇÃO DE MÚLTIPLAS HIPÓTESES DIRETA, MÉTODO DE DECODIFICAÇÃO DE MÚLTIPLAS HIPÓTESES DIRETA, APARELHO DE CODIFICAÇÃO DE MÚLTIPLAS HIPÓTESES DIRETA, E APARELHO DE DECODIFICAÇÃO DE MÚLTIPLAS HIPÓTESES DIRETA. A presente invenção fornece um método para codificação/decodificação de múltiplas hipóteses direta de um bloco de imagens. Informação de movimento de um bloco atual, incluindo dois índices de quadro de referência direto e dois vetores de movimento, é seletivamente codificada em um fluxo de bits de acordo com um modo de codificação atual. Informação de movimento que não está codificada é induzida de um decodificador de acordo com uma regra predefinida. O método suficientemente utiliza uma correlação entre informações de movimento de um bloco de imagens e uma correlação de informações de movimento entre um bloco de imagens atual e um bloco de imagens adjacente ao bloco de imagens atual.
