Claim 0:
1. An apparatus for capturing analog-modulated video broadcasting signals, the apparatus comprising:
grouped on an expansion card for a computer server, a controller, a plurality of N capture channels, each of the N capture channels producing a respective video transport stream provided as input to a multi-channel virtualization module delivering frames carrying data of a respective video transport stream among the N respective video transport streams;
wherein each of the N capture channels comprises:
an input interface powered by a low-noise power supply arranged to receive a respective modulated video broadcasting input signal within an input frequency band;
a low-noise radio frequency distribution amplifier with a single input and dual outputs, arranged to, on the basis of the respective modulated video broadcasting input signal, produce a first amplified input signal and a second amplified input signal within the input frequency band, wherein the first amplified input signal is within a satellite broadcasting frequency band and the second amplified input signal is within a cable and/or terrestrial broadcasting frequency band;
a first tuner configured to receive the first amplified input signal and to downconvert it from the satellite broadcasting frequency band in order to generate a first baseband signal;
a second tuner configured to receive the second amplified input signal and to downconvert it from the terrestrial and/or cable broadcasting frequency band in order to generate a second baseband signal; and
a demodulator configured to receive the first or second baseband signal as input and to generate the respective video transport stream on the basis of said received baseband signal.
