Abstract

The invention relates to a hand-held DLP multimedia intelligent projection system. The hand-held DLP multimedia intelligent projection system comprises a video input interface, a format converting unit, a storage medium interface, a WIFI module, an Android processor, a DMD display driver, a projection optical machine, a central processor, and the like. The format converting unit is used for converting a video data into a first TTL signal; the Android processor is used for converting the first TTL signal into a second TTL signal, or decoding and playing a video file read from the storage medium interface or a media data stream received by the WIFI module, and synchronously converting the decoded video data into a third TLL signal; the DMD display driver is used for generating an image drive signal based on the second TTL signal or the third TLL signal; and the projection optical machine is used for projection based on the image drive signal. The hand-held DLP multimedia intelligent projection system is fully functional and provides intelligent experience for users; meanwhile, a battery is internally installed, and the volume is small, therefore the carrying is convenient.

Description

technical field [0001] The invention relates to a projector, in particular to a hand-held DLP multimedia intelligent projection system. Background technique [0002] A projector is a device that can project images or videos onto a screen, and can be connected to a computer, VCD, DVD, BD, game console, DV, etc. through different interfaces to play corresponding video signals. Projectors are widely used in homes, offices, schools, and entertainment venues. According to different working methods, there are different types such as CRT, LCD, and DLP. The current projectors are generally relatively large in size, and only realize simple projection functions. Connect a computer or other terminal equipment to the projector through a connecting cable, and then the video source output by the computer or other terminal equipment can be enlarged and projected. single. Contents of the invention [0003] The object of the present invention is to provide a hand-held DLP multimedia inte...
