Abstract

MÉTODO E UM APARELHO PARA TRANSFERIR UM FLUXO DE VÍDEO A presente invenção refere-se a um método para transferir um fluxo de video tendo uma primeira resolução de um primeiro equipamento de usuário para um segundo equipamento de usuário tendo uma tela maior e sendo capaz de oferecer uma pluralidade de segundas resoluções que são mais altas que a primeira resolução, em que um ou mais terceiros equipamentos de usuário também estão recebendo fluxos de video através da mesma entidade de rede que tem uma capacidade de largura de banda limitada, o método compreendendo: executar uma operação de otimização para determinar a segunda resolução a ser selecionada entre a pluralidade de segundas resoluções no equipamento de usuário alvo para o fluxo de vídeo, em que a operação de otimização compreende: usar funções de utilidade como uma entrada para a operação de otimização, as funções de utilidade tendo sido determinadas antecipadamente e indicando respectivamente para cada fluxo de vídeo a qualidade percebida por um usuário dependendo da resolução do fluxo de vídeo e da taxa de dados alocados, em que a operação de otimização calcula uma medida de qualidade combinada com base nas funções de utilidade para os fluxos de vídeo, a medida de qualidade combinada sendo calculada tal como para descobrir entre a pluralidade de possíveis resoluções e taxas de dados que podem ser designadas para o segundo equipamento de usuário, e entre a pluralidade de possíveis taxas de dados que podem ser designadas para os fluxos de vídeo recebidos pe- los terceiros equipamentos de usuário após a transferência do fluxo de video, a resolução e taxas de dados a ser designadas para os segundo e terceiro equipamentos de usuário após a transferência para as quais a medida de qualidade combinada alcança seu ideal ou extremo; e selecionar a segunda resolução e as taxas de dados para os fluxos recebidos pelos segundo e terceiros equipamentos de usuário após a transferência do fluxo de video de acordo com o resultado do procedimento de otimização de tal maneira que a medida de qualidade combinada alcança seu extremo.
