Abstract: An apparatus and a method of building an IP based video service system in a hybrid-fiber-coaxial network are provided to capsulate IP in a subscriber device including a cable modem, thereby transmitting a video signal to an IP video output device of any type through universality and an address system of an IP protocol. An IP decapsulation unit(210) transmits a video signal to a headend after a header is deleted from a video signal of a packet type transmitted by an IP(Internet Protocol) based video server(109). The headend capsulates the received video signal from the IP decapsulation unit by an MAC(Media Access Control) header. An IP capsulation unit(230) performs internet protocol capsulation of the video signal received from the head end.

Abstract: A method and an apparatus for sharing a key and performing mutual authentication for a downloadable limit reception system are provided to perform safe secret communication by registering its own public key through a TA(Trusted Authority) and distributing the public key to a counterpart. A downloadable limit reception terminal generates a pair of a public key and a private key by using a specific algorithm(S701). A terminal certificate issue is requested from the highest trusted authority through a security communication channel of an authentication server by using the generated key(S702). The forgery or modulation of the terminal certificate issued from the highest trusted authority through the security communication channel is checked(S705). The terminal authentication request message is transmitted based on the checked terminal certificate(S706). The identical authentication server is confirmed by comparing the authentication server identification information included in the terminal certificate issued from the highest trusted authority with the authentication server identification information by using the terminal authentication response message received from the authentication server(S710).

Abstract: A method and an apparatus for receiving an upstream data packet in a channel bonding way are provided to receive data transmitted to a cable modem CMTS(Cable Modem Termination System) through several upstream channels in the upstream channel bonding way defined by DOCSIS(data over cable service interface specifications) 3.0. An upstream demodulator(509) receives a data packet transmitted from a cable modem and converts the received packet. An upstream processing unit(503) adds packet re-combination information to the data packet received from the upstream demodulator. An upstream segment processing unit(505) re-combines the data packet received from the upstream processor in response to the packet re-combination information. An upstream channel band allocation unit(501) transmits information comprising a data allocation band and an allocation interval to the cable modem and provides the packet re-combination information to the upstream processor.
