Description

Technical Field

[0001] The utility model belongs to the technical field of set-top boxes, in particular to a set-top box with expandable functions. Background Art

[0002] At present, the set-top boxes used for digital TV reception on the market generally adopt a customized model, that is, the hardware functions of the set-top boxes are determined when the final product is formed. If cable operators want to expand the functions of the set-top boxes or provide new services, they can only do so by replacing them with new set-top boxes, which greatly increases the cost of upgrading the functions of the set-top boxes.

[0003] According to the publicly disclosed set-top box with expandable functions (publication number: CN 201717946 U), it includes a set-top box host, which is connected to a function expansion module through an external port, and the function expansion module and the set-top box host form an integral structure without separation in appearance. The utility model conveniently realizes the expansion of the set-top box function under the premise of ensuring the integrity of the set-top box appearance, so that when cable operators provide new services to users, they do not need to replace the existing set-top box, but only need to install new function modules for users, and the appearance of the existing set-top box is not damaged. The above application cooperates with components such as the set-top box host and the function expansion module, which makes it difficult to realize the automatic push function, thereby increasing the burden on users, wasting time and energy, and needs to be improved.
