Abstract

MÉTODOS, DISPOSITIVOS E SISTEMA DE GERAÇÃO E PROCESSAMENTO DE FLUXO DE BITS. A presente invenção se refere a métodos, dispositivos e um sistema de geração e processamento de fluxo de bits. O método de geração de fluxo de bits compreende: determinar se deve realizar uma operação de alinhamento de Contagem de Ordem de Imagem (POC) em todo e/ou uma parte de um fluxo de bits de acordo com as exigências de aplicação; e gravar informações de identificação e controle no fluxo de bits de acordo com o resultado de determinação. As informações de identificação e controle compreendem informações de indicação sobre se deve-se realizar a operação de alinhamento de POC geral e/ou parcial no fluxo de bits. A flexibilidade no controle de fluxo de bits pode ser melhorada.
