Abstract

A network cooperation-based low power type charged broadcasting set-top box and a controlling method therefor, the set-top box sub-dividing a standby mode of the set-top box into an active standby mode, in which only background functions are processed without processing a main function, and a passive standby mode, in which no functions are processed; extending the passive standby mode occupation time to more than that of the active standby mode; and including a way of transitioning between operating modes by exchanging information regarding the set-top box through an inter-cooperation between a charged broadcasting network and the set-top box, thereby reducing the power consumption of a processor (SoC) which processes multimedia contents and minimizing the power consumption while the set-top box is in standby mode.

First claim

What is claimed is:

1. A set top box control method based on network cooperation, the method comprising:
periodically transmitting, by at least one set top box, an operation status message indicating an operation status of the at least one set top box in accordance with a message generation cycle set in accordance with a control message received from a power management server on a network to the power management server;
periodically transmitting, by the power management server, the control message to the at least one set top box in accordance with the message generation cycle of the control message, managing operation status information for the at least one set top box in accordance with the operation status message indicating the operation status of the at least one set top box received from the at least one set top box in a database, and monitoring the operation status of the at least one set top box in accordance with the control message;
in response to the generation period expires but the operation status message indicating the operation status of a corresponding set top box corresponding to a current operation mode of the corresponding set top box is not received, transmitting, by the power management server, a message for shifting an operation mode to the corresponding set top box;
analyzing, by the power management server, watching patterns of a user related with the corresponding set top box and obtaining watching pattern information including a time zone when a broadcast television program is watched in the corresponding set top box; and
shifting, by the corresponding set top box, the operation mode of the corresponding set top box in accordance with the message and the watching pattern information, wherein the operation mode of the corresponding set top box includes an on mode and an off mode and further includes an active standby mode and a passive standby mode depending on whether to support a background function, and wherein the shifting of the operation mode includes performing, by the corresponding set top box, a resetting process of turning off all power devices and rebooting the all power devices in accordance with the message in response to the power management server does not receive the operation status message on the operation status of the network connected passive standby mode of the corresponding set top box.

2. The set top box control method of claim 1 , wherein the passive standby mode includes a standalone passive standby mode and the network connected passive standby mode which maintains a communication status with a network device including the power management server in accordance with an operation of a communication dedicated processor of the corresponding set top box.

3. The set top box control method of claim 1 , wherein the operation status message indicating the operating status of the at least one set top box which is transmitted from the at least one set top box includes a set top box unique address, a current operation mode, or information on a normal or abnormal operation status.

4. The set top box control method of claim 1 , wherein the control message which is transmitted from the power management server includes information on a set top box unique address, an operation mode shifting command of the corresponding set top box, a current operation mode, an operation mode to be shifted, a timer value for a shifting time of the operation mode or the message generation cycle, a set top box reset command, and information on a normal or abnormal operation status of the corresponding set top box.

5. The set top box control method of claim 1 , wherein the shifting of the operation mode includes shifting, by the corresponding set top box, the operation mode into another operation mode among the on mode, the active standby mode, or the passive standby mode in accordance with the message in response to the power management server does not receive a the operation status message on any one operation status among the on mode, the active standby mode, and the passive standby mode of the corresponding set top box.

6. The set top box control method of claim 1 , wherein the power management server remotely controls the corresponding set top box on the network to operate in the passive standby mode longer than in the active standby mode to reduce power consumption of the corresponding set top box.

7. The set top box control method of claim 1 , further comprising: shifting, by the corresponding set top box, the operation mode in accordance with the timer time and the operation mode which is input by manipulating the remote controller by the user.

8. The set top box control method of claim 1 , further comprising: transmitting, by the power management server, a message including a timer time information to update electronic program guide (EPG) information or the firmware and control the at least one set top box to shift the passive standby mode into the active standby mode at the corresponding time, and then transmitting EPG update or firmware update after the time, to control the at least one set top box to update the EPG information or the firmware.

9. The set top box control method of claim 1 , further comprising: transmitting the control message including the operation time information for a predetermined operation mode of the at least one set top box obtained by analyzing and calculating broadcast time of a program which is expected to be watched by the user to the at least one set top box, setting, by the at least one set top box, a time in a timer to shift the operation mode into on mode, active standby mode, or passive standby mode when the set time of the timer expires.

10. A set top box power management device for controlling at least one set top box based on network cooperation, the set top box power management device comprising:
a database which stores operation status information for the at least one set top box on a network; and
a set top box power management unit which interworks with the at least one set top box to periodically exchange messages, periodically transmits a control message to the at least one set top box in accordance with a message generation cycle of the control message, receives an operation status message on an operation status of the at least one set top box which is periodically transmitted by the at least one set top box in accordance with the message generation cycle set in accordance with the control message to manage the operation status information for the at least one set top box by the database and monitor the operation status of the at least one set top box in accordance with the control message,
wherein in response to the set top box power management unit does not receive the operation status message on the operation status of a corresponding set top box corresponding to a current operation mode of the corresponding set top box at a time when the message generation cycle expires, with reference to the database, the set top box power management unit transmits a message for shifting the an operation mode to the corresponding set top box,
wherein the set top box power management unit analyzes watching patterns of a user related with the corresponding set top box, obtains watching pattern information including a time zone when a broadcast television program is watched in the corresponding set top box, and controls shifting the operation mode of the corresponding set top box based on the watching pattern information, wherein the operation mode of the at least one set top box includes an on mode and an off mode and further includes an active standby mode and a passive standby mode depending on whether to support a background function, and wherein the shifting of the operation
