The invention relates to a communication system between a receiver 101 and a terminal 102, allowing the transmission and the processing of coded audiovisual data on said terminal of limited resources, via a communication link 105 of limited capacity. To this end, the communication system is characterized in that said receiver comprises selection means applied to said data stream, according to a bi-directional control signal exchanged with said terminal, for providing selected data sent towards said terminal. This invention is a cost-effective solution since processing steps are shared between the receiver and the terminal: the receiver is mainly responsible for the storage or forward management in dependence on what can be processed by the terminal, while said terminal mainly handles the rendering and display of said received selected data.
A communication system comprising a receiver for receiving a data stream containing scene description information and a terminal for communicating with said receiver via a communication link, characterized in that said receiver comprises selection means applied to said data stream based on a bi-directional control signal exchanged with said terminal, for providing selected data which are to be sent to said terminal.
A method for data exchange between a receiver receiving a data stream containing scene description information and a terminal via a communication link, characterized in that it comprises a selection step applied to said data stream based on a bi-directional control signal exchanged with said terminal for providing selected data which are to be sent to said terminal.
