Abstract
A system provides interactive control of broadband services. There are today systems which offer distributive services, for instance analog cable-TV, analog satellites and acting terrestrial TV-networks. A paradigm shift, however, has been initiated in connection with that digital transmissions have started, which make possible a more spectrum efficient transmission. This means, for instance, that a broadband service such as digital transmission of video channels can be developed by making it interactive. One solution can be to use the GSM-system. For example, services which require low capacity in uplink can utilize the SMS-function is GSM. At larger demand of bandwidth GSM's data services can be utilized, which however prevents calls when the telephone is used for interactive communication. The invention solves this problem by interactive traffic between the transmitting and receiving equipment being managed by an interactive center (IC) which is arranged to execute wanted broadband service. IC in addition is in connection with a distributive centre (DC) for distribution of the broadband signals out on the telecommunications network.
