[0001] The utility model belongs to the technical field of set-top boxes, and in particular relates to a set-top box smart card installation structure. Background Art

[0002] A set-top box, or digital video converter box, or STB for short, is a device that connects a TV set to an external signal source. It can convert compressed digital signals into TV content and display it on the TV set. In addition to the images and sounds that analog TVs can provide, the set-top box can also receive digital content, including electronic program guides, Internet pages, etc.

[0003] The set-top box smart card is a hardware encryption device, which is generally used to encrypt and decrypt digital TV signals. Only with the correct smart card can the encrypted signal be viewed. When installing the existing set-top box smart card, the staff generally directly inserts the smart card into the reserved hole. Since the reserved hole is set larger than the smart card when it is factory-set to ensure that the smart card can be smoothly inserted, a large gap is generally left at the joint between the reserved hole and the smart card. At this time, if the set-top box is in a tilted state, it is easy for the smart card to fall off from the reserved hole. For this reason, a set-top box smart card installation structure is provided.
