A simulation system for testing performances of television (TV) tuners (50) attached to a plurality of computers (5) is disclosed. The system includes: a plurality of players (1), each for transmitting an original signal comprising audio and video data formatted in a corresponding data format; a plurality of frequency adjusters (2), each for receiving a corresponding original signal from one of the players and changing the original signal into an adjusted signal having a fixed frequency; at least one frequency mixer (3) for combining all the adjusted signals into an aggregated signal; at least one hub (4) for distributing the aggregated signal to each of the computers via a coupled TV tuner respectively. Each of the computers is used for decoding various TV programs at different signal frequencies in an emulated TV channel, and generating a test report on the performance of each TV tuner. A related method is also disclosed.
