Improvements to a time control system for apparatuses structured according to said main patent and characterized in that the connection detector includes electronic components which analyse the various voltages and consumptions of the apparatus, detecting its operating state - on, off or on, standby - as a function of which it adapts the signals received to the rest of the electronics of the system, and in that the electronic channel-discrimination unit includes electronic components which analyse the signal received by the channel selected to adapt it to the rest of the electronic signal according to the price set for each one of the channels, in order to establish a different viewing cost per unit of time and channel so that it is possible to enable one or a number of channels where the price per time unit is zero - free channel(s) - and/or establish one other or other prices per real viewing time with respect to the remaining channels. Applicable to electronic control systems. <IMAGE> |
