Abstract
Provided is an apparatus and method for providing a video service flow using a dual scheduler for a headend cable modem in a Hybrid Fiber Coax (HFC) network. The apparatus may include: a service flow processing unit to determine whether a packet corresponds to a registered video service flow, when the packet is received; and at least one channel transmitter to schedule a packet corresponding to the registered video service flow and a packet not corresponding to the registered video service flow so that a transmission rate of the registered video service flow is guaranteed, and to thereby transmit the packets.
