Abstract: Provided are a transmission apparatus and a transmission method for a subscriber network in a cable network. A passive optical network (GPON) receiver receives data packets through a fiber line using a plurality of optical wavelengths from a head end. A micro cable modem termination system (CMTS) converts the data packets into a data over cable service interface specification (DOCSIS)-based DOCSIS frame and transmits the DOCSIS frame to at least one subscriber device through a coaxial line.

Abstract: An apparatus of providing Internet Protocol Television (IPTV) reception information includes a Cable Modem (CM) to provide an interactive service that enables an IPTV broadcast content including service information, and a Data Over Cable Service Interface Specification (DOCSIS) Media Access Control Management Message (MMM) based on the service information to be received from a cable network, or enables an IPTV broadcast content control signal to be transmitted from a subscriber to the cable network, and a Set-Top Box (STB) to decode the IPTV broadcast content received from the CM and to transmit the decoded IPTV broadcast content to a display device. The STB may receive an IPTV broadcast content selected by a user using Layer 2 (L2) reception information bounded to the IPTV broadcast content. Thus, it is possible to receive an IPTV broadcast content selected by a user directly without a delay time.

Abstract: A terminal authentication apparatus and method in a Downloadable Conditional Access System (DCAS) is provided. The terminal authentication method may determine whether terminal authentication information, received from a DCAS terminal, is valid by referring to a database, may transmit DCAS image information and pairing information about the terminal authentication information to a user terminal, when the terminal authentication information is valid, and thereby may enable the DCAS terminal to set the user terminal based on the pairing information.

Abstract: Provided is an outdoor optical node unit (ONU) and method for converting/combining frequencies, and an apparatus and method for converting/combining frequencies in a cable television headend system.

Abstract: Disclosed are a method and apparatus for providing broadcast service information in a cable network. A data transmitting method of the broadcast service information providing apparatus includes receiving IPTV broadcast contents, configuring broadcast service information on the IPTV broadcast contents, assigning a virtual channel to the broadcast service information; and transmitting, to a terminal, the broadcast service information to which the virtual channel is assigned. A data receiving method of a terminal includes receiving broadcast service information to which a virtual channel is assigned, displaying configuration information of the virtual channel, selecting the virtual channel, and decoding the broadcast service information assigned to the selected virtual channel to display the decoded information.

Abstract: A method of selectively using a CA application of a terminal, the method including: searching a CA application table when a service of fee-based contents is requested, and determining whether a corresponding CA application is installed; and extracting a key required for descrambling a broadcasting signal using the CA application, when the CA application is installed based on a result of the determining.

Abstract: Provided is an outdoor optical node unit (ONU) and method for converting/combining frequencies, and an apparatus and method for converting/combining frequencies in a cable television headend system.

Abstract: An apparatus for receiving MPEG-2 A/V data by using a cable MODE is disclosed. The apparatus includes: a cable MODEM for separating broadcasting data and broadcasting supplementary data by demodulating an input signal; and a multiplexer for multiplexing the separated broadcasting data from the cable MODEM with broadcasting data inputted from other input source, and outputting the multiplexed broadcasting data to an external cable card.
