Problems solved by technology

[0003] However, so far, the research on the energy-saving technology of digital TV receivers mainly focuses on how to reduce the standby power consumption, but there is little research on how to reduce the power consumption of digital TV receivers during normal operation
In fact, it is not enough to try to reduce the power consumption of the digital TV receiver only when it is in standby mode, because in terms of the current user's usage and the working conditions of the TV receiver, the unnecessary energy generated by the digital TV receiver during normal operation The power consumption is also considerable, and many circuits and peripheral devices that do not perform their main functions are always in a state of energy consumption, and these are often ignored in the design stage of the manufacturer and the use stage of the user

Embodiment Construction

[0032] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0033] The present invention realizes modularized power supply according to different situations such as whether the digital TV receiver is connected to a modem MODEM, whether it is working with HDD, whether it is inserted into a universal interface / conditional access card, whether it is watching TV or listening to data broadcasting. On the premise of analyzing the real-time working status and energy consumption index of each functional module and peripheral equipment included in the digital TV receiver, the operating status of each functional module and peripheral equipment is intelligently monitored through software, so that it is turned off when it is not necessary Zero power consumption or low power consumption state, so as to reduce unnecessary energy consumption of the TV receiver during normal operation.

[0034] like figure 1 As shown, the digital set-top bo...

Abstract

This invention provides one digital television receiver energy saving system, which comprises main control chip and intelligent power management module, wherein, the said chip analysis and test digital television receiver comprises each function modules and it's outside prompt work status and energy index and sends order signals to power management module to control each function module and outside power matching. This invention also provides one digital television receiver energy saving method.

Description

technical field [0001] The invention relates to the field of digital television receivers, in particular to an energy-saving system and method for digital television receivers. Background technique [0002] Along with the coming of "Beijing 2008 Digital Olympics" and the country's overall launch of the overall conversion of cable TV from analog to digital, digital TV sets, digital set-top boxes and digital TV all-in-ones are rapidly entering thousands of households. But at the same time, these digital products will cause huge energy consumption, and a considerable part of this energy consumption is unnecessary energy waste, which will not only cause huge economic waste, but also bring great harm to the country's environmental protection work. heavy burden. Worldwide, the energy crisis has led to stricter restrictions on the energy consumption indicators of home appliances in the international market. High efficiency, energy saving, and environmental protection are the inevi...
