Problems solved by technology

[0004] 1. The uncontrollable power consumption means the increase of power consumption. Nowadays, energy depletion is imminent and environmental problems are extremely serious. Reducing power waste is a global trend and a basic national policy of the country.
[0005] 2. The increase in power consumption is accompanied by the increase in heat. For thousands of user groups, excessive heat is the key to affecting the life of the device and a safety hazard.
[0006] 3. Power consumption is also a kind of loss. Today, with the vigorous promotion of green energy conservation and environmental protection, and the implementation of tiered electricity prices, power consumption control is undoubtedly a big problem that needs to be solved urgently
[0007] 4. The greater the power consumption, the greater the radiation. Although it is not enough to cause harm to the human body, adverse reactions such as dizziness will occur over time
[0009] At present, the energy efficiency level of my country's digital TV receiver products (such as set-top boxes) energy efficiency standards will be divided into 3 levels, level 1 is the target value, and products that meet the requirements of level 1 are advanced and efficient products. Currently, there are no or only a few products in the market. Level 2 is the energy-saving evaluation value of the product, and products that reach the energy-saving evaluation value are also advanced and efficient products, and the proportion in the market is not much at present; Level 3 is the energy efficiency limit value of the product, and products lower than this index are Eliminate the product, its production and sale should be banned

Embodiment 1

[0036] Such as figure 1 As shown, an energy-saving control method for video stream playback terminal equipment, the video stream playback terminal equipment in this embodiment is a digital TV set-top box, and the digital TV set-top box is provided with a dynamic power management (Dynamic Power Management, referred to as "DPM") and Dynamic Voltage and Frequency Scaling (Dynamic Voltage and Frequency Scaling, referred to as "DVFS") processors, energy-saving control processing modules and memory, the energy-saving control processing module includes monitoring the current processor working status and user QoS (Quality of Service) service index monitoring unit, control unit for acquiring processor working status and adjusting unit for adjusting processor working status. The memory includes EROM (Eraseable Read Only Memory) or PROM (programmable read-only memory), and the data will not be lost due to power failure.

[0037] During the use of the digital TV set-top box, energy-savin...

Embodiment 2

[0047] Such as figure 2 As shown, the video stream studio terminal device in this embodiment is a computer, and the energy saving control method in this embodiment includes the following steps:

[0048] In step S201, the monitoring unit monitors and acquires user QoS service index information in real time;

[0049] In step S202, the control unit obtains the corresponding processor working state according to the obtained user QoS service index information, wherein a relatively low user QoS service index corresponds to a relatively low operating frequency and / or operating voltage;

[0050] In step S203, the adjustment unit adjusts the operating frequency and / or operating voltage of the processor according to the acquired operating frequency and / or operating voltage.

[0051] The method for obtaining the corresponding processor working status in step S202 of this embodiment may be a correspondence table method or a direct calculation method, and the correspondence table method ...

Embodiment 3

[0054] refer to figure 2 As shown, this embodiment is basically the same as Embodiment 2, except that the video streaming studio terminal device of this embodiment is a handheld electronic device, a tablet computer or a mobile phone.

Abstract

The invention relates to an energy-saving control method for a video code stream playing terminal. The video code stream playing terminal is equipped with a processor supporting dynamic power management and dynamic voltage and frequency scaling, an energy-saving control processing module, and a memory. The energy-saving control processing module comprises a monitoring unit, a control unit, and an adjusting unit. The energy-saving control method comprises that the monitoring unit acquires user QoS service index information and current processor operative state information in real time and transmits the information to the control unit; that the control unit acquires processor operative state information corresponding to the current user QoS service index information according to the current user QoS service index information, and transmits a processor operative state control signal to the adjusting unit, and that the adjusting unit adjusts the operative state of the processor according to the received control signal. Compared with a method in the prior art, the energy-saving control method has advantages of a good energy-saving effect and low production and installation price.

Description

technical field [0001] The present invention relates to an energy-saving control method, in particular to an energy-saving control method for video code stream playback terminal equipment. Background technique [0002] Today's huge user groups, increasingly large-capacity video, and the continuous emergence of new services of "three-network integration" require the deployment of a large number of video streaming studio terminal equipment (such as set-top boxes, etc.). However, due to the backwardness and lack of energy-saving control technology, the mainstream products in the market basically do not adopt energy-saving control technology or adopt "pseudo-standby" technology, resulting in the power consumption of video streaming studio terminal equipment (such as set-top boxes, etc.) far greater than people's expectations. [0003] If the power consumption cannot be effectively controlled, there will be the following four adverse effects: [0004] 1. Uncontrollable power con...
