ABSTRACT:
A cable receiver is disclosed that comprises a multimedia channel unit to receive a multimedia signal, and a multimedia processor to process the multimedia signal. The cable receiver further comprises a cable modem to perform data communication with an information provider that provides appendix information about the multimedia signal and a Web server that hosts a predetermined Web page through a cable network. An information processor adds appendix information to the multimedia signal, and a Web browser transmits request information received for the Web page according to a user's selection and processes the received Web page for the user. The cable receiver further comprises a controller to control data transmission of the cable modem, the information processor, and the Web browser to transmit the appendix information and the Web page to the information processor and the Web browser. Thus, the present invention provides a cable receiver capable of supporting Internet service without incurring the additional cost associated with a cable modem.
