Patent ID: 7382784

Claim:
An apparatus for classifying digital broadcast channel data according to virtual channel connection (VCC), comprising: an optical signal receiver for converting an optical signal from an optical line terminal (OLT) into an ATM (Asynchronous Transfer Mode) cell that is classified according to the VCC; a VCC-based ATM cell classifier for detecting header information and a payload part from the classified ATM cell of each VCC delivered from the optical signal receiver; a controller; a plurality of PID (Program ID) analyzers for receiving respective payload parts of an ATM cell corresponding to one VCC from the VCC-based ATM cell classifier, extracting PID of each broadcast channel from digital broadcast channel data included in the payload part, and outputting broadcast channel data in the broadcast channel data included in the payload part under the control of the controller; and a switch for receiving broadcast channel data output from the PID analyzers and switching the received broadcast channel data to a broadcast channel desired by a subscriber under the control of the controller, wherein the controller updates broadcast channel information by receiving header information of the classified ATM cell of each VCC front the VCC-based ATM cell classifier, receives the broadcast channel desired by the subscriber, and controls the PID analyzers to output the desired broadcast channel according to VCC information with the desired broadcast channel included therein so that the output broadcast channel is matched to the subscriber.
