Abstract: Apparatus for reproducing data from a selected digital television signal, transmitted in packet form as vestigial-sideband (VSB) amplitude-modulation (AM) of a carrier, has a tuner for selecting a digital television signal and converting it to a final intermediate-frequency signal, which is digitized by an analog-to-digital converter before synchrodyning to baseband in the digital regime. VSB synchrodyning circuitry synchrodynes the digitized final intermediate-frequency signal to baseband in the digital regime to generate in-phase and quadrature-phase baseband signals. The quadrature-phase baseband signal is lowpass filtered to generate an automatic frequency and phase control (AFPC) signal for controlling a local oscillator in the tuner, so that the in-phase baseband signal comprises digitized VSB symbol coding. Symbol decoding circuitry responsive to the VSB symbol coding generates a digital data stream.

Abstract: A plural-conversion digital television signal receiver that embodies the invention upconverts digital television signal from a selected television channel to a UHF initial I-F signal.

The low-band final I-F signal is digitized and demodulated in the digital regime to generate a baseband signal.
