CONTROL OVER COAX FOR TV SIGNAL RECEPTION DEVICES

摘要

TV signal distribution system comprising a programmable filter device(1) which receives the TV signal and is connected to the end-user TV (3) via an interface device(2), the interconnections between the devices being made by coaxial cables and a programming unit (4) being connected via the interface device (2) to the coaxial network. Method for programming a programmable filter device in a TV signal distribution system, comprising the steps of providing an interface device (2) in the coaxial network, connecting a programming unit (4) to the interface device(2) and exchanging communication signals between the programming unit (4) and the programmable filter device (1) over the interface device (2) and the coaxial network,for programming the filter circuit device (1).
