A television link device is provided to restore a remote control signal stably by amplifying and restoring the signal which is inputted after being modulated. A set top box(21) receives a satellite broadcasting signal or cable broadcasting signal to amplify the received broadcasting signal and remove a noise from the received broadcasting signal so that a corresponding broadcasting signal may be outputted by being adjusted to a desired channel. The set top box includes a CPU which performs a control operation according to an input signal. A high frequency signal module(22) modulates the broadcasting signal outputted from the set top box and outputs the modulated broadcasting signal to an RF output end. In addition, the high frequency signal module restores an ASK signal and outputs the restored ASK signal to the CPU. |
