Problems solved by technology

[0003] However, when watching a presentation video, users usually need to review certain content because they do not understand clearly or miss a certain period of content, and sometimes the content that users need to understand needs to be fast forwarded to watch
However, when the user looks back or fast-forwards, he can only remember the time of the content to be watched, and then adjust the progress bar to an approximate position. Due to incorrect time or inaccurate adjustment, many attempts are often required If you don’t know the approximate time, you can only choose blindly. For a long video, finding the correct content is basically equivalent to rewatching the video, which is a waste of time.
[0004] In short, when a user records and watches a presentation video through the existing technology, the fast-forward or rewind function provided for the user cannot enable the user to quickly and accurately find the content he / she wants to watch

Embodiment 1

[0078] see figure 1 as shown, figure 1 It is a flow chart of a presentation recording method provided in this embodiment. Among them, the presentation can include multiple pages, and the following steps need to be performed when recording the presentation video:

[0079] S101. During the video recording process of the presentation, monitor the operation of the presentation.

[0080] The main purpose of monitoring the presentation is to determine whether the presentation switches from the current page to the next page during the show. When a user uses a presentation to give a speech, he usually explains or reads the content of the page being projected on the screen. Since the page of the presentation is switched, the content or the subject of the user's speech has changed accordingly, for example , the current presentation page is 1, and the user can explain the content of page 1. When the presentation page is switched from 1 to 2, the user generally starts to explain accord...

Embodiment 2

[0111] The presentation video recorded in Embodiment 1 needs to be played with a correspondingly improved player to reflect the corresponding improvement effect, such as figure 2 as shown, figure 2 What is shown is a flow chart of a presentation video playing method. Wherein, during the process of recording the video, when it is monitored that the presentation is switched from the first page to the second page, the correspondence between the page identification information of the second page and the time stamp is stored, The time stamp is a time offset from the recording start time point to the time point when the switching action occurs. The specific video playback steps are as follows:

[0112] S201. During the video playing process, read the stored corresponding relationship;

[0113] S202. Generate prompt information according to the corresponding relationship, and provide it to the user, so that the user can select the content to be viewed according to the prompt inf...

Embodiment 3

[0128] Corresponding to the presentation video recording method provided in Embodiment 1, this embodiment also provides a presentation video recording device, such as Figure 4 As shown, the device includes:

[0129] The presentation monitoring unit 401 is configured to monitor the operation of the presentation during the video recording process of the presentation.

[0130] The page identification information and time stamp acquiring unit 402 is configured to acquire the page identification information and time stamp of the second page when it is monitored that the presentation is switched from the first page to the second page, and the time stamp is from The time offset from the recording start time point to the current time point.

[0131] The correspondence storage unit 403 is configured to store the correspondence between the page identification information and the time stamp, so that when the video player plays the video, the stored correspondence information is used to...

Abstract

The embodiment of the invention discloses a video recording method and a device for presentation files. A presentation file is composed of a plurality of pages. The method comprises the steps of during the video recording process, monitoring the operation condition of the presentation file; upon monitoring the condition that the presentation file is switched from a first page to a second page, acquiring the page identifier information and the timestamp of the second page, wherein the timestamp is composed of the time offset from the starting time point of the video recording process to the current time point; storing the corresponding relationship between the page identifier information and the timestamp. In this way, when a video player is playing the above video, a prompt message is generated based on the stored information of the above corresponding relationship. After that, the prompt message is supplied to a user. The prompt message is used for positioning the contect of a to-be-checked particular page identifier during the video playing process. According to the technical scheme of the invention, the user can quickly and accurately find out the to-be-checked content.

Description

technical field [0001] The invention relates to the technical field of video recording, in particular to a presentation video recording method and device. Background technique [0002] The use of presentations (PPT, PowerPoint) has been very popular today, especially in some conferences, classrooms, lectures and other scenarios, most of the speakers or lecturers will rely on pre-edited presentation files to speak or explain. However, these scenarios are generally aimed at a fixed number of people.
