Abstract

"MéTODO PARA TRANSMITIR A INFORMAçãO DE VìDEO, CODIFICADOR, DECODIFICADOR, E, SINAL REPRESENTANDO A INFORMAçãO CODIFICADA". A invenção relata um método para transmitir a informação de vídeo, na qual ao menos o primeiro fluxo de bit (510) e o segundo fluxo de bit (520) são formados. O primeiro fluxo de bit (510) compreende ao menos um quadro de vídeo, e o segundo fluxo de vídeo (520) compreende ao menos um quadro (524) de vídeo preditivo. Os parâmetros de codificação ao menos parcialmente diferentes são usados com a codificação dos quadros do primeiro fluxo de bit (510) e do segundo fluxo de bit (520). Ao menos um quadro do primeiro fluxo de bit (510) está sendo transmitido, e a transmissão é comutada do primeiro (510) para o segundo fluxo de bit (520). Na comutação, a transmissão do primeiro (510) para o segundo fluxo de bit (520), é transmitido um quadro (550) de comutação secundário, o qual tem sido codificado usando os parâmetros de codificação do segundo fluxo de bit (520) e ao menos um quadro de referência do primeiro fluxo de bit (510). O quadro (550) de comutação secundário é usado como um quadro de referência na reconstrução de pelo menos um quadro (524) de vídeo preditivo do segundo grupo de quadros de vídeo. A invenção também relata um codificador para codificar a informação de vídeo, um decodificador para decodificar a informação de vídeo, e um sinal representando a informação de vídeo codificada.
