technical field

The present invention is about utilizing embedded system such as mobile phone, PDA mobile phone (smart phone), PDA (personal digital assistant) and digital camera etc. to carry out the broadcasting of briefing.

Background technique

For most people, almost all "presentations" are made by software like Power-Point, because it can contain many different animations, sound effects and illustrations. Although most of the presentations of "Briefings" are displayed on a large screen by a projector, in some occasions it is only necessary to display it on a small screen without bringing a laptop. When you don't bring your own laptop, but want to borrow someone else's (such as a client's) computer, the "presentation" is easy to be copied and stolen.

Therefore, it is necessary to play "presentation" through a small screen with a very lightweight machine. In particular, digital cameras have always been used to view photos or videos, but have never been used to view presentations. As for mobile phones (especially camera phones), they are only used to view photos or videos.

Detailed ways

Please first refer to FIG. 1 for a schematic diagram of the environment in which the present invention is used. Personal computer 70 basically all has a storage device 75 (such as hard disk, CD (compact disk), pen drive, magnetic disk etc., or any combination of above-mentioned storage devices), and the user can utilize presentation application program 25 (such as PowerPoint presentation software) to produce an original presentation file 20 (such as a PowerPoint presentation file). The key point of the present invention is to allow the user to make a file 50 suitable for an embedded system to play a presentation when an original presentation file 20 is played on a personal computer 70, so that the user can use a portable and portable embedded system to play the presentation.

In order to achieve this purpose, an embedded system presentation making main program 40 needs to be stored in the storage device 75, so that the processor of the personal computer 70 can execute the embedded system presentation making main program 40 so as to make a presentation suitable for an embedded system. File 50. Embedded system briefing making main program 40 mainly includes two functional programs of video recording program 41 and recording program 42 for marking (tag). Please refer to FIG. 2 for the flowchart of the present invention, and refer to FIG. 3 together. and FIG. 4 shows the format of the presentation file 50 with respect to embedded systems.

The following presentation application 25 takes the PowerPoint application as an example.

Step 200:

Play the original briefing file 20 and execute the main program 40 for producing the embedded system briefing.

The presentation application 25 mainly has an editing mode and a playback mode; in the playback mode, the image of the original presentation file 20 is displayed on the screen of the personal computer 70 as a full image.

After the embedded system presentation making main program 40 is executed, it is preferable to execute it in the background (background) mode, that is, there will be no operation interface or information displayed on the image when the original presentation file 20 is played, so that the user can operate the presentation application In the process of program 25, there is no feeling of the existence of the main program 40 for making presentations of embedded systems.

Since the current operating system of the personal computer 70 can execute multiple programs at the same time, and another program can be called or started between programs, so the principle behind the implementation of the main program 40 for making presentations in the embedded system will not be described here.

Step 201:

Record video.

After the original presentation file 20 enters the playback mode, the image recording program 41 starts to record the presentation image displayed in the original presentation file 20 .

Please refer to FIG. 3 , assuming that the original presentation file 20 has three presentation screens:

The first presentation screen, such as the presentation image 21a: display: "This".

The second briefing picture, such as the briefing image 21c: display: "is a". The second presentation screen first displays "is" (such as the presentation image 21b), and when the user presses the "↓" key 712, the second presentation screen displays "is a".

The third presentation screen, such as the presentation image 21d: display: demo.

When step 201 is executed for the first time, the briefing video 21a is recorded.

Step 202:

Change image key 30 is pressed?

Taking the PowerPoint application program as an example, the "page down" key 711, the "↓" key 712, the "→" key 713 in the keyboard 71 and the left mouse button 721 of the mouse 72 can all make the presentation present the next screen (not necessarily the next screen). One page), the next screen may basically be the next page, but it may be the same page but with text changes, graphics changes, or startup animations, etc. The meaning of changing the image key 30 in this manual is to make the presentation show the next screen. Taking the PowerPoint application as an example, the changing image key 30 can be the "page down" key 711, the "↓" key 712, and the "→" key 713 And the left mouse button 721 of the mouse 72.

If the change image key 30 is pressed, the main program 40 for making the presentation of the embedded system proceeds to step 203 . Of course, in the case of the presentation application 25, if the change image key 30 is pressed, the presentation will present the next screen.

Step 202 is actually a step of monitoring at any time. When the image key 30 is not changed, step 201 is continued.

Step 203:

Record the mark (tag).

For example, the briefing image 21a is displayed originally, and after the change image key 30 is pressed, the recording program 42 for marking (tag) records tag1, which is the end point of the presentation image 21a data, and of course tag1 is also the starting point of the presentation image 21b .

In the embodiment, the presentation images are sequentially generated tag1, tag2 and tag3 due to the pressing of the change image key 30, and the presentation images are the presentation image 21a, the presentation image 21b, the presentation image 21c and the presentation image 21d in sequence.

Please refer to FIG. 3 , although tag0 can indicate the starting position of the first presentation image (such as the presentation image 21 a ), tag0 is actually unnecessary because the position when the first presentation image starts to be recorded is known. Of course, for the convenience of management, tag0 can also be automatically generated when step 201 is executed for the first time (it is not necessary to have the change image key 30 pressed).

Step 204:

Original Briefing File 20 End of Play?

After the original briefing file 20 is played, go to step 205, otherwise go to step 201. It should be noted that step 204 is actually a step of monitoring at any time.

Please refer to Fig. 3, tag4 may not be needed actually, because it is the last part, of course, for the convenience of management, the end of the last briefing image may also have a tag (mark), and in this embodiment, tag4 may also be generated.

Step 205:

Complete Embedded Systems Presentation Presentation File 50.

In fact, steps 201 and 203 are continuing to build the embedded system presentation presentation file 50. Since the original presentation file 20 has been played, the embedded system presentation presentation file 50 can be completed and can be stored in the storage device 75 (such as using or a pen drive, or hard drive).

Please refer to FIG. 3 , the embedded system display briefing file 50 includes a briefing data area 54 to store presentation images 21a, 21b, 21c, and 21d; Which location of the briefing data area 54 is stored that tag0~tag4 points to.

As for the embedded system display briefing file 50, there can be quite a variety of formats, and even the embedded system display briefing file 50 can include multiple files, such as files for storing presentation images 21a, 21b, 21c, 21d, and storing tag0~ file for tag4. Please refer to FIG. 4 , which shows an embodiment of the format of the briefing file 50 related to the embedded system. The format of the Embedded System Display Presentation File 50 is planned into four areas, which are introduced as follows:

Slot name area 51: store the file name.

Mark (tag) recording area 53a: record each mark (tag), such as Tag1~Tag4.

Tag pointing area 53 b : record the position where each tag points to the presentation data area 54 , for example, the image data address and the audio data address of Tag1 in the presentation data area 54 . It should be noted that step 201 in the above-mentioned embodiment only describes recording images, but some presentations include sound effects such as voice or music, so step 201 can also record sound. When there is sound recording, the mark (tag) should include The image data address and the audio data address are recorded. The above mark (tag) recording area 53a and mark (tag) pointing area 53b correspond to the mark (tag) area 53 in FIG. 3 .

The briefing data area 54 is used for storing image data and audio data.

After the embedded system display briefing file 50 is made, it can be used by the embedded system. The embedded system is the most common such as mobile phone, PDA mobile phone (smart phone), PDA (personal digital assistant) and digital camera. Taking the digital camera 80 as an example, please refer to FIG. 5 and FIG. 6. The circuit structure of the digital camera 80 basically includes a processor 81, a memory 82, a screen 83, an image capture module 84, and an operation interface 85. High-end digital cameras also include Components of the microphone and speaker (not shown). Usually the memory 82 can include built-in memory and extended memory (such as SD or CF CARD, etc.), and the built-in memory stores system software and application programs. The presentation file 50 of the embedded system can be stored in the expanded memory so that the built-in application can read it.

Since the embedded system display briefing file 50 includes the above-mentioned mark (tag) area 53, the user can use the left and right keys or the up and down keys of the operation interface 85 (usually the embedded system has at least the left and right keys or the up and down keys) to operate the embedded system. The system displays the playback of the presentation file 50 . A flow chart of a basic application program for playing an embedded system presentation presentation file 50 can be shown as follows:

Step 700:

i=0, the variable i is set to 0.

Step 701:

Display_Image(Tag(i)to Tag(i+1)), that is, to play the image pointed from Tag(i) to Tag(i+1).

Step 702:

If the next key (next key, usually the right key or down key) of the operation interface 85 is pressed, then i=i+1. But when i>i's maximum value, i=i's maximum value (for example, if Tag(4) is the last Tag, then the maximum value of i is 4), or the playback ends.

If the last key (previous key, usually the left key or the upper key) of the operation interface 85 is pressed, then i=i-1, but when i<0, i=0.

Go to step 701.

The above-mentioned embedded system is applied to the digital camera 80 and can also be applied to the mobile phone 80a (as shown in FIG. 8 ), because the mobile phone 80a also has hardware such as a processor, a memory, a screen 83a, and an operation interface 85a.

Similarly, above-mentioned embedded system is applied to digital camera 80 and can also be applied to personal digital assistant (PDA) 80b (as Fig. 9), because personal digital assistant 80b also has processor, memory, screen 83b and operating interface 85b etc. hardware.

It should be noted that, in order to reduce the file size of the presentation file 50 displayed by the embedded system, if the presentation image is a still image, only one image can be recorded. Of course, the image data or audio data stored in the embedded system display presentation file 50 can be compressed data, such as compressed in MJPEG, MP3, MP4 and other formats.

To sum up, the present invention, regardless of its purpose, means, and efficacy, shows its characteristics that are quite different from those of the prior art, which is a major breakthrough. However, it should be noted that the above-mentioned embodiments are only illustrative to illustrate the principles and effects of the present invention, and are not intended to limit the scope of the present invention. Any person familiar with the art can modify and change the embodiments without violating the technical principle and spirit of the present invention. The protection scope of the present invention should be described in the scope of patent application mentioned later.
