Set-top box which is multiple remote control encoding mode compatible under standby state and method

Abstract

The invention discloses a set-top box which is compatible with a plurality of remote control coding modes under a standby state, wherein the method comprises: when a mainboard circuit detects a standby request, the mainboard circuit transfers coded information of a remote control standby key used by a local host to a control circuit, then transmits a standby request instruction to the control circuit, and the control circuit enables the mainboard circuit into a standby state after receiving the standby instruction through controlling a power circuit; when an infrared receiving circuit receiving circuit receives a wake-up remote control signal, the control circuit performs a decoding treatment to the wake-up remote control signal according to the coded information of the remote control standby key, and transmits the control signals to wake-up the power circuit and to make the mainboard circuit in a normal work state after correctly decoding. The invention enables the set-top box to compatibly identify various format remote control codings under a low-power consumption state, and has advantages of simple structure and easy implementation.

Description

technical field [0001] The invention relates to a method for realizing a standby circuit, in particular to a method for realizing compatibility with multiple remote control codes in a standby state, and a set-top box using the method. Background technique [0002] The development of modern science and technology has brought people's lives into the digital age. Various household electronic consumer products are pouring into thousands of households like a tide. The wide use of household appliances also makes the originally limited energy more tense. Green environmental protection has become our Popular words in life now. Therefore, household appliances with low power consumption follow the trend. [0003] More and more families use digital set-top boxes, and with the enrichment of functions, digital set-top boxes have become the new darling of household electronic consumption in the digital age. However, after the existing low-power-consumption set-top box (referring to the ...

Problems solved by technology

However, after the existing low-power-consumption set-top box (referring to the power consumption after standby is less than 1W) is on standby, the main board circuit that realizes digital TV reception and processing functions is closed during standby, and the control circuit that is in normal operation in the standby state is in the standby mode. When receiving the wake-up remote control signal from the remote control, the control circuit may not be able to recognize the activation request remote control information due to the different coding methods of the remote control signal used by various remote controls, resulting in failure to trigger the start-up of the set-top box

[0004] Therefore, how to solve the current technical problem that the set-top box cannot recognize various formats of remote control codes in a state of low power consumption due to the use of different remote control code formats by different domestic radio and television systems is urgent.
