Embodiment Construction

[0030] All features disclosed in this specification, or steps in all methods or processes disclosed, may be combined in any manner, except for mutually exclusive features and / or steps.

[0031] Any feature disclosed in this specification (including any appended claims, abstract and drawings), unless expressly stated otherwise, may be replaced by alternative features which are equivalent or serve a similar purpose. That is, unless expressly stated otherwise, each feature is one example only of a series of equivalent or similar features.

[0032] Such as figure 1 As shown, the system includes a front control board with a single-chip microcomputer, a main board, and a power board. The power board is connected to the main board through a cable. The boards are powered separately, and the power board has the function of independently reducing the power supply of the main board. The microcontroller on the front control board is used for standby and power-on control. It communicates...

Abstract

The invention discloses a standby, timing shutdown and timing boot controlling device of a set top box. The device comprises a mainboard, a front control plate and a power strip. The power strip connects with the mainboard through a flat cable. The front control plate connects with the power strip and the mainboard respectively through two flat cables. The front control plate is provided with a one-chip microcomputer processor used for controlling standby and boot. A host on the mainboard monitors a standby button signal and sends a command to the one-chip microcomputer, the one-chip microcomputer sends a standby signal to the power strip, the power strip reduces power supplied to the mainboard, operation of the mainboard is stopped, only power supply of the one-chip microcomputer and an infrared receiving terminal are reserved, thus low-power standby is realized. A standby control command is sent by the mainboard, an abnormal condition appeared at next boot time caused by that a plurality of state information is not saved timely when power is off is avoided. When detecting a timing shutdown time period, the host sends a command to the one-chip microcomputer, the one-chip microcomputer outputs low level to the power strip, the power strip starts power supply of the mainboard, the set top box restarts, thus timing boot and shutdown functions are realized.

Description

[0001] technical field [0002] The invention relates to the technical field of digital TV set-top boxes, in particular to a set-top box standby and timing switch control device. Background technique [0003] In recent years, China's digital TV industry, especially the cable digital TV industry, has continued to develop rapidly. The digital TV set-top box market has developed simultaneously with the overall conversion of digital TV, and the market size has continued to grow. Therefore, the set-top box is becoming an indispensable household device for more and more users. [0004] At present, the normal working power consumption of most digital TV set-top boxes in my country is generally 8 to 15 watts. When most set-top boxes are in the standby state, they only turn off the audio and video output of the set-top box, and then display the indicator light as the standby state. The power consumption in standby mode is almost the same as that in normal operation. The circuit desi...
