Multiplex output broadcasting receive system using CASconditional access system of single set-top box

摘要

The present invention already sikidoe through the installed network (RF line) connecting a single set-top box and a plurality of TV receivers, respectively installed in different places, filter technology combines the remote control IR data within the RF line to the TV and in the home or a specific place by RF a / V signal is implemented to co-exist, with each other to the other encrypted multiple channels using a single identification card to disengage the password, through a single set-top box allows the user independently in each spaced apart support assists to watch TV, it relates to a multiple-output broadcast receiving system using a conditional access function of a single set-top box, which in other places is not a set-top box is installed through a remote controller to enable remote control of the set top box, the present invention jimyeo watch the broadcast through each spaced apart fingers plurality of TV receivers associated with a single set-top boxes with only one authentication card possible, according to a separate track construction and costly RF (UHF) remote control for set-top box remote control at each spaced apart support there is a need to purchase a transceiver missing effect. ; A digital broadcast receiver, a set-top box, TV receiver, the filter technology, LPF, HPF, RF modulator, a coaxial cable, conditional access device, CAS (Conditional Access System)
