Description

A projector that can directly capture and play audio-visual multimedia

technical field

The utility model relates to a projector, in particular to a projector capable of directly extracting and playing audio-visual multimedia with a processing chip that can directly play out digital audio-visual files recorded on a memory card or an optical disc.

technical field

Computer digital technology is advancing with each passing day, and in recent years, digital playback has been mostly used for audio and video playback. The device for playing audio and video generally includes a DVD player, which plays audio and video content through a display, or projects video content onto a curtain with a projector for users to watch.

In the above-mentioned playback device, the projector is usually connected to a personal computer host or a notebook computer with a signal output line during application, and the digital video and audio recorded in the hard disk is captured by the personal computer host computer or notebook computer. The files are converted into digital image signals and audio signals through the audio-visual player program in the computer, and the image signals are transmitted to the projector through the signal line, and then projected to the screen by the projection lens of the projector.

However, the above-mentioned projector must be connected to a personal computer or a notebook computer with a signal cable in application, and the digital audio-visual files in the computer are captured through the personal computer or notebook computer, that is, the audio-visual content to be played by the projector is Stored in a personal computer or notebook computer, when the user uses the projector, the projector must be equipped with a computer, so when the user goes out to use, he must carry the projector and a personal computer or notebook computer at the same time , so that the video and audio content to be watched can be played smoothly through the projector. However, when the user needs to go out to use the projector, it is often inconvenient to carry the bulky personal computer or notebook computer together, and it is necessary to go to the playback site. The operation of connecting the personal computer and the projector in series often causes the user to be extremely inconvenient in use, and there is obviously a need for improvement.

In view of this, the author of this case made research and innovation, revealing a projector that can directly capture and play audio-visual multimedia.
