Abstract: A method and system for improving a channel change rate using a conditional access table/program map table (CAT/PMT) to be transmitted in an out-of-band (OOB) band. First main data including a channel ID of a scrambled channel and Conditional access table (CAT) information corresponding thereto and defining a version is transmitted from a main program of a conditional access system (CAS) headend. Second main data including the channel ID and Program map table (PMT) information corresponding thereto and defining a version is transmitted from a main program of a demux/remux device. Third main data generated by receiving and combining the first and second main data is included in service information (SI) and is transmitted in an Out-of-band (OOB) band. After extracting only the third main data from the transmitted Service information (SI) in response to a channel change event signal, encrypted broadcast content of each channel is released and provided to a user.

Abstract: An apparatus and method for managing a cable modem using a Web server are disclosed. The cable modem, which includes the Web server, enables an Internet connection of a user computer by connecting the user computer to a cable television line. The cable modem is enabled to communicate with the user computer on which a Web browser is mounted. If the Web server receives a request for management information associated with an operation of the cable modem from the Web browser, the Web server then transmits the management information to the Web browser in response to the management information request. Further, if the Web server receives a setup request for operation parameters associated with an operation of the cable modem from the Web browser, the Web server then transfers the operation parameter setup request to a controller managing the operation parameters in response to the operation parameter setup request.
