ABSTRACT:
An MPEG-4 based multimedia system in connection with a service provider therefore, and a remote communication device therefore, is presented. The interactive content based remote communication unit simplifies and reduces the number of steps and buttons required for receiving interactive service by the use of MPEG-4 encoded data. Additionally, new ways are disclosed for the data processing at the service provider side. Further, an improved way of exchanging data between the service provider (broadcaster, cable provider) and the customer (viewer) is presented. Still further, there is disclosed how digital equipment (server, set-top box, remote control unit and display) involved in the data processing can be optimized for the task of controlling the available channel bandwidth and displaying the data.
