Abstract

SINALIZAÇÃO DE DESCRIÇÃO DE CENA PARA CONFERÊNCIA MULTIMÍDIA. A presente invenção refere-se a sistemas e métodos para fornecer uma sessão de grupo tridimensional imersiva. Várias modalidades incluem métodos e dispositivos para sinalizar uma descrição de uma cena com componentes de mídia potencialmente oriundos de diferentes partes. Em vários aspectos, um gráfico de cena pode ser sinalizado através de um protocolo de descrição de sessão (SDP) durante uma configuração de sessão de protocolo de iniciação de sessão (SIP). Em várias modalidades, o gráfico de cena pode incluir respectivos nós de saída gráficos atribuídos para serem controlados por cada um da pluralidade de dispositivos de computação participantes em uma sessão de grupo tridimensional imersiva.
