IP address acquisition method for controlling standby mode of set-top box, and set-top box and power management server performing the method
First Claim
1. A method of acquiring an Internet protocol (IP) address of a set-top box performed by a power management server, the method comprising:
- determining whether a state of a set-top box changes from a broadcasting state in which a broadcasting service is provided to a passive standby state in which a network connection between the set-top box and a headend providing the broadcasting service is blocked;
receiving, from the set-top box, state information associated with an IP address allocated to the set-top box for the network connection in response to the state of the set-top box changing to the passive standby state;
reducing a power consumption of the set-top box in response to the state of the set-top box changing to the passive standby state;
transmitting, to the set-top box, a state change command to maintain the network connection for the IP address allocated to the set-top box based on the received state information;
transmitting, through a separate microcontroller processor of the set-top box, a state change command in response to a state maintenance time of routing information of the set-top box being exceeded; and
broadcasting a video content to the set-top box.

Abstract
A method of acquiring an Internet protocol (IP) address to control a standby mode of a set-top box, and the set-top box and a power management server performing the method are disclosed. The method may include determining whether a state of the set-top box changes from a broadcasting state in which a broadcasting service is provided to a passive standby state in which a network connection between the set-top box and a headend providing the broadcasting service is blocked, receiving state information associated with an IP address allocated to the set-top box for the network connection in response to the state of the set-top box changing to the passive standby state, and transmitting, to the set-top box, a state change command to maintain the network connection for the IP address allocated to the set-top box based on the received state information.

9. A method of acquiring an Internet protocol (IP) address performed by a set-top box, the method comprising:
-
receiving an IP address allocated by an IP management server configured to manage the IP address of the set-top box for a network connection between the set-top box and a headend when power is input to the set-top box; determining whether a state of the set-top box changes from a broadcasting state in which a broadcasting service is provided to a passive standby state in which the network connection is blocked; transmitting, to a power management server, state information associated with the IP address allocated to the set-top box when the state of the set-top box changes to the passive standby state; reducing a power consumption of the set-top box in response to the state of the set-top box changing to the passive standby state; receiving, from the power management server, a state change command to maintain the network connection for the IP address allocated to the set-top box in response to the state information; maintaining the network connection for the IP address by changing the state of the set-top box to an active standby state in which the network connection of the set-top box is available in response to the received state change command; receiving, at a separate microcontroller processor of the set-top box, a state change command in response to a state maintenance time of routing information of the set-top box being exceeded; and receiving broadcast video content at the set-top box. - View Dependent Claims (10, 11, 12, 13, 14, 18)
