Problems solved by technology

However, when the participants want to review the presentation text data after a period of time and look at the presentation text data or its electronic file, they may forget why they made such notes on the presentation text data at the beginning, or for certain information in the presentation document. Some content cannot be understood
In severe cases, it is even impossible to understand the context of the briefing documents, which makes the participants quite troubled
[0005] Although there are currently cameras that can record and record on the spot, the audio-visual files output by the cameras are very large, and the participants cannot carry them with them to review them.
[0006] Even if the participants use the recording pen to record the voice of the presenter privately to output an audio file, but the participants review the text of the briefing in the future, there may be a situation where they listen to the audio file and do not know that the presenter is speaking in the briefing file. Part of it also caused distress to the participants

Abstract

A projection device coding image and sound synchronously to form audio-video synchronous file is featured as receiving the first image signal TFIS ) by the first processing unit ( TFPU ) for outputting the second image signal ( TSIS ) , connecting projection unit to FPU for receiving TSIS and for projecting image corresponding to TSIS on a wall , recording user sound explaining image corresponding to TSIS for outputting the first sound signal ( TFSS ) , connecting the second processing unit ( TSPU ) to recording unit for receiving TESS to output the second sound signal ( TSSS ) , connecting audio-video coding unit to TSPU and TFPU for synchronously coding TSIS and TSSS to output audio-video synchronous play file.

Description

technical field [0001] The present invention relates to a projection device, and in particular to a projection device capable of synchronously encoding images and sounds as audio and video synchronously playing files. Background technique [0002] Since the invention of the optical projection system, with the rapid development of science and technology, it has been gradually applied to various fields, such as entertainment equipment and commercial affairs equipment, using the image projection system to enlarge the projection film in large conference speeches, or It is a large rear projection TV used in business. The current projection device can be an image output projection device, a real object projection device and a slide projection device. In terms of an image output projection device, [0003] When the image output and projection device is electrically connected with the computer, the image output and projection device can project the picture of the computer onto the ...
