Background technology
In today that digital technology develops rapidly, projector has become the standard configuration in demonstration places such as multi-media classroom, multi-functional conference hall and big-and-middle-sized club; Projector is provided with and has been widely used in home theater field and mobile office aspect, the more and more polynary change of product.Along with the progressively appearance of home projector and the continuous maturation of digital television techniques, use projector to watch the high definition television industry just progressively to popularize.But people often need during with traditional projector time-consuming take a lot of work carry out certain operations, when particularly being connected, can't accomplish that " plug and play " operate very easily with computing machine or laptop computer.Because traditional projector must be equipped with computer when the play multimedia resource or other broadcast source connects and could normally use,,, condition restriction cause traditional projector can not playing image owing to can't providing computer or other broadcast source because in many instances.
Summary of the invention
The objective of the invention is integrating traditional projector and micro computer forms one together and is mainly used in HD video and multimedia function projectors easy to use such as teaching resource, film, DVD.
The invention provides a kind of multimedia function projector; Comprise optical projection system; Also comprise computer system; On the circuit board of said computer system central processing unit is installed, said central processing unit is connected with TF card slot, USB interface, VGA input interface, HDMI input interface, AV input interface, memory modules, flash memory module, power module, audio output interface, video format conversion module, and said computer system is connected on the optical projection system through the video format conversion module.
Said computer system also preferably includes an infrared remote sensing receiver module, and said infrared remote sensing receiver module is connected on the central processing unit.
Said computer system also preferably includes a TV input interface, and said TV input interface is connected on the central processing unit.
Also preferably include a loudspeaker that links to each other with central processing unit.
Also preferably include a cellular phone signal shielding device that links to each other with central processing unit.
Said flash memory module preferably stores the An Zhuo system.
Also preferably include a video on-demand system that links to each other with central processing unit.
Multimedia function of the present invention projector connects as one optical projection system and computer system; Have computer function and multi-media player function when projection can be realized concurrently; Be applicable to the broadcast of multiple format video, and can control the reception of all kinds of videos that it is very convenient to use through telepilot.
