Problems solved by technology

With the rapid development of our country's national economy and the substantial improvement of people's living standards, especially the rapid development of TV technology, various ultra-large-screen and ultra-thin TV sets have come out one after another. On the other hand, with the continuous increase of TV functions, People often adopt the TV set-top box to make up for the functions that the TV set cannot achieve. When the TV set-top box of the prior art is in use, it is usually placed on the top of the TV set or placed next to the TV set. It is difficult to place a set-top box on the top of the ultra-thin TV. If it is placed next to the TV, it will take up space and not coordinate with the TV. This is because the ultra-thin The TV set itself is to reduce the occupied space, and it is placed next to it but increases the occupied space virtually, forming an unattractive and uncoordinated state; the ideal position of the set-top box should be attached to the back of the TV set, but the prior art The set-top box uses infrared remote control or buttons for operation and control to achieve the purpose of use. If it is placed on the back of the TV, it is impossible for the set-top box to receive remote control signals, and it is difficult to use buttons to operate. Make the set-top box practically useless; on the other hand, the set-top box needs to be equipped with a power cord to be connected to the mains before it can be used, which not only causes inconvenience in use but also makes the wiring increase unsightly
