Abstract

The invention provides a set-top box with the projecting function and a method thereof for realizing the projecting function, wherein the set-top box comprises a set-top box module, the set-top box further comprises an MCU, a video control module and a projecting module, wherein the MCU is used for realizing the control of the set-top box according to the orders of users, the video control module is used for receiving electrical signals transmitted by the set-top box module and controlling the projecting module to project images according the electrical signals, the projecting module is connected with the video control module for receiving the electrical signals transmitted by the video control module and projecting images according to the electrical signals. The technical proposal of the invention enables users to be easy to watch televisions / films through the projecting mode under the condition that only the set-top box exists, video images are not displayed on the televisions and are displayed on a curtain wall instead according to local conditions, which brings new experiment for users, compared with allocating another projectors by users, the set-top box has the advantages of lower cost and more convenient use.

Description

technical field [0001] The invention belongs to the technical field of set-top boxes, in particular to a set-top box with projection function. Background technique [0002] With the gradual conversion from digital TV to analog TV, the set-top box has become a necessary household appliance in the family. On the other hand, with the development of projector technology, the price of the projector is getting cheaper, the size is getting lighter and smaller, and the image quality is getting better and better. Many users are very interested in using the projector to play movies or other programs. [0003] But the existing projector and the set-top box are separated, and the set-top box can only play the TV program picture through the TV, but cannot play through the projector. Therefore, it is necessary to provide a set-top box with a projection function, so that the screen of a TV program can be played by projection. Contents of the invention [0004] The object of the present...
