Set top box automatic energy-saving control method and system, and set top box

Abstract

The invention provides a set top box automatic energy-saving control method. The method includes the steps of monitoring an output end of an HDMI high-definition output module, so as to judge whether an HPD signal is received; monitoring an output end current I1 of a CVBS standard-definition output module, so as to obtain the variation situation of the output end current I1; and monitoring an output end current I2 of a YPbPr output module, so as to obtain the variation situation of the output end current I2, and setting a variation threshold value of the output end currents I1 and I2. According to the set top box automatic energy-saving control method and system and set top box provided by the invention, the output ends of the HDMI high-definition output module, CVBS standard-definition output module and YPbPr output module are monitored, control of functional modules of a set top box is performed according to the monitoring situation, and when corresponding outputs of the functional modules have no load, the corresponding modules are closed; and when the corresponding outputs of the functional modules are connected to a load, the corresponding modules are opened, thereby effectively improving the performance of saving power utilization of the set top box.

Description

technical field [0001] The invention relates to the technical field of communications, in particular to a set-top box automatic energy-saving control method, system and set-top box. Background technique [0002] A set-top box, also known as a digital video conversion box, is a device that connects a TV to an external signal source. It can convert the compressed digital signal into TV content and display it on the TV. Signals can come from cable, satellite dishes, broadband networks, and terrestrial broadcasts. With the advancement of telecommunication network system, computer network system and cable TV network system integration technology, the content received by the set-top box is not only the image and sound that can be provided by analog TV, but also the ability to receive digital content, including electronic program guides, Internet pages, Subtitles, etc., enable users to watch digital TV programs on existing TV sets, and conduct interactive digital entertainment, e...

AI Technical Summary

Problems solved by technology

If the set-top box is not turned off or standby when the TV is not in use, the set-top box will still be in use, which will cause a waste of power

And most of the set-top boxes on the market are in the power-on state, and all their output interfaces are working regardless of whether the user uses them. waste of electricity
