A second coaxial-connector may be added to a TV receiver that directly samples digital or analog format TV signals, which may be received via a first coaxial-connector. The second coaxial-connector may enable backwards compatibility with one of plurality of available consumer audiovisual devices, wherein Audio/Video (A/V) analog and/or digital modulation format feeds from the consumer audiovisual device may be inputted directly into the TV receiver via the second coaxial-connector. The A/V feed from the consumer audiovisual devices may be demodulated via a common demodulator for similarly modulated TV signals in the TV receiver. Filtering and/or amplification of the local A/V feed may be performed via dedicate components; however, analog-to-digital conversion of the local A/V feed may either be performed via the dedicated converter or via a common-path converter. The local A/V feed may also be demodulated directly, via a dedicated demodulator.
