PURPOSE: A digital broadcasting community watching system is provided to separate an antenna and a tuner from a receiver and share the antenna and the tuner with different receivers. CONSTITUTION: An antenna(41) receives one or more digital broadcasting signals. A plurality of tuners(43a-43c) tune one of the digital broadcasting signals received in the antenna(41) according to an external control signal. A plurality of distributors(44a-44c) distribute the digital broadcasting signal tuned in each tuner to a plurality of channels. A plurality of digital receivers(45a-45c) receive the broadcasting signal of a desired channel from a corresponding tuner through the distributor, decode the received broadcasting signal, and output the decoded broadcasting signal. If the desired channel is inputted from the digital receiver, a control unit(47) confirms states of a plurality of the tuners(43a-43c). If the tuner tuning a digital broadcasting signal including the inputted channel exists, the control unit(47) controls the digital receivers(45a-45c) so that the digital receiver receives a broadcasting signal of a corresponding channel through the distributor connected to the tuner. If the tuner tuning the digital broadcasting signal including the inputted channel does not exist, the control unit(47) selects a tuner which is not connected with the digital receivers(45a-45c). The control unit(47) controls the digital receivers(45a-45c) so that the digital receiver receives a broadcasting signal of a corresponding channel through a distributor connected to the selected tuner.
