Embodiment 1

[0044] Such as figure 1 Shown is a schematic structural diagram of a set-top box proposed in this application, which mainly includes a POE module 101, a step-down circuit 102, and a power supply switch circuit 103. The following is a detailed introduction to its important components:

[0045] (1) POE module

[0046] The POE module plays the role of a compensation power supply in this application, and is used to provide compensation power supply for the set-top box according to the actual power consumption of the set-top box. Since the voltage provided by the POE module does not match the working voltage of the set-top box, it is also necessary to perform voltage transformation on the voltage of the POE module.

[0047] (2) Step-down circuit

[0048] In the embodiment of the present application, the step-down circuit plays a role in converting the power supply voltage of the POE module into a voltage suitable for the set-top box in the present application. Wherein, the step-...

Embodiment 2

[0065] This application proposes a method for adjusting the power supply of a set-top box, which is applied to the set-top box proposed in the first embodiment above. The distributed voltage, and load the voltage output by the step-down element to the main board of the set-top box through the power supply switch circuit.

[0066] Such as figure 2 As shown, it is a schematic flow chart of a method for adjusting the power supply of a set-top box proposed in this application, and it can be seen from the figure that it includes:

[0067] S201. When the set-top box needs the POE module to provide compensation power supply, convert the power supply voltage output by the POE module into a voltage suitable for the set-top box through the step-down circuit.

[0068] S202. Load the voltage output by the step-down element to the mainboard of the set-top box through the power supply switch circuit.

[0069] In a specific application scenario, the step-down circuit converts the power su...

Abstract

This application proposes a set-top box, including a POE module, a step-down circuit and a power supply switch circuit, the step-down circuit is connected to the POE module and the power supply switch circuit respectively, and the power supply switch circuit is connected to the main board of the set-top box, wherein: the step-down circuit is used in the set-top box When the POE module is required to provide compensation power supply, the power supply voltage output by the POE module is converted into a voltage suitable for the set-top box; the power supply switch circuit is used to turn on when the set-top box needs the POE module to provide compensation power supply, and when it is turned on, it will step down The voltage output by the component is loaded on the motherboard of the set-top box. The POE module of the set-top box proposed in this application can compensate and supply power to the set-top box as a whole, thereby reducing the power supply load of the set-top box, enabling the set-top box to use a smaller power adapter, and reducing the manufacturing cost of the product.

Description

technical field [0001] The invention relates to the field of set-top boxes, in particular to a set-top box. The present invention also particularly relates to a method for adjusting power supply of a set-top box. Background technique [0002] Video is not only a form of entertainment, but also the main means of distance learning, communication, collaboration and service. Video already accounts for a major share of Internet traffic, and with the popularization of 4K ultra-high definition, the share will continue to grow. The development of video services is attributed to the soaring CPU / GPU processing capabilities, the popularization of ultra-broadband and mobile broadband technologies, and the promotion of cloud computing technologies. The most critical factor is IPTV or OTT (Over-The-Top) technology, especially variable bit stream coding streaming media technology and progressive download technology, which make video distribution well adaptive to network conditions.
