  • Digital television signal translator
    Patent number: 6919930
    Abstract: A tuner of a digital television signal translator tunes to receive an RF digital television signal on a first selected television channel. A demodulator provides a baseband digital television signal from the RF digital television signal to which the tuner is tuned. The baseband television signal includes a data component identifying the first selected channel. A data replacer replaces the data component identifying the first selected channel with a data component identifying a second selected channel different from the first selected channel. The output of a modulator is modulated by the baseband television signal including the data component identifying the second selected channel for transmission as a digital television signal on the second selected channel.
