Abstract

A transmission system has a primary station and at least one secondary station, which stations are coupled through a transmission medium. The stations each comprise means for transmission between the respective stations. The primary station comprises a multicarrier unit coupled to the transmission medium. On each carrier downstream frequency there are data streams, whose content is user controlled by transmission means which are common transmission medium modems. In particular the control information is meant for controlling data payload at the one or more carriers. The transmission medium comprises a partially fibre, partially coax medium. An improved flexibility at reduced cost is achieved with common cable modems when supplying user services, such as video on demand, pay per view, special television, such as high definition television services, WEB services, data, voice, or the like.
