Embodiment Construction

[0048] In order to understand the characteristics and technical contents of the embodiments of the present invention in more detail, the implementation of the embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. The attached drawings are only for reference and description, and are not intended to limit the embodiments of the present invention.

[0049] A set-top box is a device that connects a TV with an external signal source. It can convert compressed digital signals into TV content and display it on the TV. Here, the signal can come from cable, satellite dish, broadband network, and terrestrial broadcast. The content received by the set-top box can also receive data content, including electronic program guide, Internet web pages, subtitles, etc., in addition to the images and sounds that can be provided by analog TV.

[0050]The set-top box provides a variety of interface controllers for peripherals, such as t...

Abstract

The invention discloses a power consumption reduction method for a set-top box and the set-top box. The method comprises steps: when the set-top box is in a normal working mode, whether a light sleep signal is received is detected; when the light sleep signal is detected to be received, a preset processing module corresponding to N external devices is closed to enable the set-top box to be in a light sleep working mode, wherein N is no smaller than 1; when the set-top box is in the light sleep working mode, whether a quick wakeup signal is received is detected; and when the quick wakeup signal is detected to be received, the preset processing module corresponding to the N external devices is started to enable the set-top box to be in a normal working mode.

Description

technical field [0001] The invention relates to set-top box technology and dynamic management technology of power consumption of the set-top box, in particular to a set-top box and a method for reducing power consumption thereof. Background technique [0002] It is difficult to reduce the power consumption of set-top boxes (STB, SetTopBox) among many service devices, not because the set-top boxes themselves cannot achieve high efficiency and energy saving through proper power supply design and power management technology, but because the set-top box business service providers want to satisfy customers. Business requirements, such as real-time playback of on-demand movies, timely update of the electronic program guide, and immediate viewing function after power-on, etc., result in the power consumption of the set-top box being basically the same whether it is on or off. [0003] Under normal circumstances, the dynamic power consumption power management strategy of the central...
