摘要： 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.

摘要： 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.
