Benefits of technology

[0011]Another aspect of the present invention also provides a method of eliminating an IP-encapsulated portion in a headend, transmitting a video signal to a subscriber apparatus, and per

Problems solved by technology

Overhead caused by the IP encapsulation when transmitting an IP-based video to a Data Over Cable Service Interface Specifications (DOCSIS) channel may waste scarce resources of the HFC network using the ubiquitous IP protocol and an address system in order to support various viewing forms of users and to provide a multicast service of only a request program.
A DOCSIS protocol supports

Abstract

An apparatus and method of building an Internet Protocol (IP)-based video service system in a Hybrid Fiber Coax (HFC) network is provided. An apparatus for building an IP-based video service providing system, the apparatus including: an IP decapsulation unit to delete a header in a video signal in a packet form transmitted by an IP-based video server, and to subsequently transmit the video signal to a headend; the headend to encapsulate the video signal received by the IP decapsulation unit into a Media Access Control (MAC) header, and to transmit the encapsulated video signal in the packet form; and an IP protocol encapsulation unit to perform IP encapsulation of the video signal received from the headend.
