Activation pattern based standby mode scheduling for power-efficient set-top box

In this paper, activation pattern based standby mode scheduling is proposed for reducing power consumption of a set-top box during standby state where a set-top box does not receive broadcast services. The set-top box with the standby mode scheduling finds mainly used time (i.e., when users mainly uses the set-top box) and seldom used time by analyzing record of its activation pattern. The set-top box saves power consumption by scheduling passive standby mode (i.e., the lowest power mode) during seldom used time, and reduces time for activating by scheduling active standby mode during mainly used time.
