Set-top box and power supply control device and method thereof

Abstract

The invention discloses a set-top box, a set-top box power supply control device and a set-top box power supply control method. The set-top box power supply control device comprises a television electrical signal acquisition module, a signal processing module and an execution module, wherein the television electrical signal acquisition module acquires current induction signals from a television input power supply line and sends the current induction signals to the signal processing module; the signal processing module is used for receiving the current induction signals, converting the current induction signals into voltage signals and outputting power supply disconnection control signals when the voltage signals are judged to be smaller than a preset threshold value; and the execution module receives the power supply disconnection control signals from the signal processing module and disconnecting the power supply of the set-top box according to the power supply disconnection control signals. The set-top box power supply control device and the set-top box power supply control method provided by the invention can realize cut-off of the power supply of the internet protocol television (IPTV) set-top box when an IPTV user turns off (standby) the television, so that the user does not need to separately turn off the set-top box, a large amount of data stream is released, the flow pressure of the whole IPTV video link is relieved, power can be saved, the set-top box can be maintained better, and the device and the method are convenient for the user to operate.

Description

technical field [0001] The invention relates to the technical field of power supplies, in particular to a set-top box and a power supply control device and method thereof. Background technique [0002] With the rapid development of IPTV services, the data traffic on the Internet has increased sharply, and the contradiction between supply and demand has become prominent. Due to the user's operating habits, some users are not used to turning off the IPTV set-top box at the same time as turning off the TV; in addition, due to the monthly subscription unlimited time tariff policy, some monthly subscription users feel that it does not matter whether the set-top box is turned off, even if the TV is turned off. , resulting in a considerable portion of continuous data traffic. However, unnecessarily keeping the set-top box powered on not only wastes power resources and network resources, but also causes premature aging of the set-top box.

Problems solved by technology

Due to the user's operating habits, some users are not used to turning off the IPTV set-top box at the same time as turning off the TV; in addition, due to the monthly subscription unlimited time tariff policy, some monthly subscription users feel that it does not matter whether to turn off the set-top box, even if the TV has been turned off, they will not turn off the set-top box , resulting in a substantial portion of the ongoing data traffic

However, unnecessarily keeping the set-top box turned on not only wastes power resources and network resources, but also causes premature aging of the set-top box
