File conversion method and playing system

Abstract

The invention relates to a file conversion method and a playing system, wherein the method comprises the following steps: playing a computer briefing file with plural pages of briefing data firstly bybriefing software; capturing and comparing a plurality of computer pictures of the briefing data in the process of playing each page of briefing data; storing a difference block into the page of a computer-free briefing file if the difference block exists between the former computer picture and the next computer picture; switching to the next computer picture if the difference block does not exist between the former computer picture and the next computer picture and judging whether the pages of the computer pictures change or not after being switched; continuously capturing, comparing and storing the page of briefing data if the pages of the computer pictures do no change; and capturing, comparing and storing the computer pictures of the next page of briefing data till the last page of briefing data if the pages of the computer pictures change. The invention can carry out the briefing without a computer, has the same effects and functions with the original briefing contents and greatly improves the meeting convenience.

Description

technical field [0001] The present invention relates to a method for converting a computer-less presentation file into a PC-less presentation file and a system for playing the PC-less presentation file. Background technique [0002] see figure 1 As shown, it is a system architecture diagram of a known technology-using a computer for a briefing meeting, which includes a computer 10 , a projection device 12 and a screen 14 . A presentation software 102 (such as PowerPoint) and a computer presentation file 104 that can be played by the presentation software 102 are installed inside the computer 10, and data transmission can be carried out in a wired or wireless manner between the computer 10 and the projection device 12, and the computer screen that appears The computer screen is transmitted to the projection device 12, and output to the screen 14 through the projection device 12.

Problems solved by technology

[0003] Usually the main purpose of the computer 10 in the meeting room is only to play the computer briefing file 104. If the meeting is not held frequently, it seems unnecessary to place a computer 10 in the meeting room, so as not to cause waste of resources due to the low utilization rate of the computer 10, but On the other hand, if the computer 10 is not placed in the conference room, it is quite inconvenient to carry a computer 10 every time a meeting is held.

[0004] see figure 2 As shown, it is a schematic diagram of a projection device with a USB slot in the second known technology. In order to overcome the shortcomings of the first known technology, the second known technology discloses a projection device with a USB slot, including a projector body 20 , a USB slot 22 and a picture playing module 24, wherein the USB slot 22 can be combined with a removable device 26, and the picture playing module 24 can read the picture file 28 stored in the removable device 26 (such as JPG format) and play, but because the picture playing module 24 of known technology two can only play picture file 28, so when carrying out briefing, detachable device 26 inside can only store picture file 28 instead of computer presentation file (e.g. PowerPoint files)

[0005] Taking PowerPoint as an example, the computer presentation files produced by it usually contain multiple pages of presentation data. The presentation data on each page may be a picture or an animation or a combination of pictures and animations. There may also be transition effects when the presentation data is switched to the next page of presentation data. To execute animation or play the next page of presentation data, the presenter must input a switch command (enter command). These special effects and functions can only be executed through PowerPoint on the computer

[0006] And the projection device of known technology 2 can only play picture files, so the computer briefing file of PowerPoint must be converted into a plurality of picture files and be stored in a folder, if for example this computer briefing file comprises 12 pages of presentation data, it must be Converted into 12 picture files, at this time, the original animation effect of each page of presentation data and the transition effect of different pages of presentation data will no longer exist. Although the purpose of playing presentations without a computer can be achieved, the original Effects and functions that should be included in the content of the newsletter

[0007] In addition, when a presenter saves a plurality of picture files in a folder of a removable device, the name of the folder is presented in characters instead of pictures, and the characters used in different regions or countries They are also different. If the presenter wants to give a presentation in a different region or country, if the projection device provided by the region or country does not have a character code that supports the name of the folder, the presenter will not be able to identify the detachable device. The name of the internal folder. Once there are too many folders stored in the detachable device, the presenter will be forced to open the folders one by one to confirm which folder is the one he really wants to play.
