Set top box capable of switching power automatically and interface type set top box

Abstract

The invention relates to a set top box capable of switching power supply automatically which comprises a power module, a first power supply module, a second power supply module, and a power supply switching module, the first power supply module is used for supplying power to the power module through a signal interface of a TV set; the second power supply module is used for supplying power to the power module through external power; and the power supply switching module is used for switching over the first power supply module and the second power supply module to supply power for the power module. The set top box capable of switching the power is an interface type set top box and comprises a signal output interface and a power interface, the signal output interface is respectively connected with the first power supply module and the signal interface of the TV set, and the power interface is respectively connected with the second power supply module and the external power. The invention also provides an interface type set top box capable of switching power automatically. In the invention, dual power is adopted to supply power and the power supply can be switched over automatically according to the power supply condition of the power, thus although one way power of the set top box is disconnected, the set top box also can operate normally, and reliable and effective working of the set top box can be ensured.

Description

technical field [0001] The invention relates to a set-top box, in particular to a set-top box capable of automatically switching power sources. Background technique [0002] At present, with the development of digital TV technology and the promotion of digital TV, more and more digital TV terminals have entered thousands of households, and everyone needs to use receiving equipment such as TV sets and digital set-top boxes when watching TV. The set-top box and the TV are connected through multiple transmission lines of different types, and power support needs to be provided for the two devices at the same time. The use of this set-top box is complicated to connect. At the same time, if the power supply of the two devices is disconnected, the set-top box will not work normally. For example, when the set-top box is being upgraded, the power supply of the set-top box is accidentally knocked off, which cannot guarantee the reliable and effective work of the set-top box.
