Example one
Referring to fig. 1, fig. 1 is a flowchart illustrating a method for quickly viewing desktop shared history content according to an embodiment of the present application. As shown in fig. 1, a method for quickly viewing desktop shared history content according to an embodiment of the present application includes:
the speaker terminal equipment sends a screen sharing request to the server;
after the server receives the sharing request, the speaker terminal equipment sends desktop image data of the speaker terminal equipment to the server;
the server forwards the received desktop image data to the participant terminal equipment for display, and caches the desktop image data;
and the participant terminal equipment responds to the interface action and sends a review request to the server, and the server responds to the review request and calls out target image data from the cached desktop image data and sends the target image data to the participant terminal equipment for display.
In the embodiment of the application, in the desktop sharing process, the server transmits the image data shared by the desktop to the participant terminal equipment and stores the image data, so that when a user needs to review the image content shared by the participant terminal equipment, the server can call the image data which is stored in advance in response to the interface action, and therefore review can be conveniently achieved.
Examples are illustrated below:
the following interactions are all at the iPad side of the participant, and the participant is watching the shared desktop of the speaker through the iPad.
10:00AM presenter opens a PDF document;
10 x 02AM the speaker opens a chat window, hiding the PDF document;
10:03AM participant wants to review the PDF document just before, the participant swipes left to right on the iPad screen, and the PDF document at 10:00AM is displayed on the screen.
Optionally, the interface action includes any one of left/right/up/down sliding, screen re-pressing, screen long-time pressing, fingerprint input operation, multi-finger touch screen, and special-shaped sliding curve.
In the embodiment of the present application, besides the above-mentioned interface actions, a person skilled in the art may actually determine other types of interface actions, such as symbol sliding customizable by a user, touch frequency customizable by a user, number of touch fingers customizable by a user, and the like, as long as the actions do not conflict with other trigger actions already used by the system, which is not limited in the present application.
Optionally, after caching the desktop image data, the server further includes:
starting desktop image data processing, calculating historical key frame candidate pictures according to a preset algorithm on the cached desktop image data, and storing the historical key frame candidate pictures to an internal memory.
Optionally, there are a plurality of historical key frame candidate pictures, and when the first target image data is sent to the participant terminal device, the remaining historical key frame candidate pictures are placed in a sending list and sorted.
In the embodiment of the application, the server calls the first historical key frame picture by responding to the interface action of the user and sends the first historical key frame picture to the participant terminal equipment, meanwhile, the server also puts the remaining historical key frame candidate pictures into a sending list, and can determine the arrangement sequence in the list according to the time of the list or the sequence of the operation times of the user during playing, so that the subsequent interface action of the user can be responded in time, and the response speed of the system is improved.
Optionally, the calculating historical key frame candidate pictures for the cached desktop image data according to a predetermined algorithm includes:
s11, setting a maximum time threshold T of the cache, and destroying the desktop image data exceeding the maximum time threshold T from the memory;
s12, carrying out similarity calculation on the desktop image data, storing the desktop image data with the similarity smaller than an initial similarity threshold A, and otherwise, carrying out abandon processing;
s13, judging whether the number of key frames in the unit time L of the key frames is larger than a threshold value P, if so, executing a step S14, otherwise, executing a step S11;
s14, increasing the initial similarity threshold A;
s15, judging whether the number of key frames in the unit time N of the key frames is larger than a threshold value M, if so, executing a step S16, otherwise, executing a step S11;
s16, the initial similarity threshold A is increased, and then the step S11 is executed.
In the embodiment of the application, image data exceeding a maximum time threshold T (for example, 30 min) is firstly destroyed from a memory in a predetermined algorithm and is no longer used as cache data; then, the maximum number P of key frame images allowed in the unit time L (e.g., L seconds) of the key frame and the maximum number M of key frame images allowed in the unit time N (e.g., N minutes) of the key frame are set, and the number of key frame images is controlled accordingly, so as to ensure that, for example, the same PPT picture is not repeatedly stored, which not only saves the storage space, but also improves the review efficiency of the user.
In addition, the number of the key frames is controlled in real time by adjusting the similarity threshold, which is also the inventive point of the present application, because the content of the adjacent PPT pages may have only slight differences, but the adjacent PPT pages still belong to different PPTs, at this time, the server must store the adjacent PPT pages as key frame images, otherwise, the review of the subsequent user is affected, and the present application sets a way of gradually increasing the similarity threshold, so that the number of the key frame images can be controlled, and particularly similar PPT pages are also distinguished.
Optionally, the calculating historical key frame candidate pictures for the cached desktop image data according to a predetermined algorithm includes:
s21, calculating a similarity threshold B between the currently received and cached desktop image data and the latest cached desktop image data;
s22, if the similarity is larger than the similarity threshold B, adding the same mark to the similarity threshold B;
and S23, determining the desktop image data arranged at the top layer of the screen in the desktop image data with the same mark as a historical key frame candidate picture.
S24, executing the steps S21-S23 in a circulating way.
In the embodiment of the present application, it may also be determined whether the received desktop image data is, for example, of the same PPT page by marking the desktop image data, and if so, the desktop image data placed on the top layer of the screen is determined as the historical key frame candidate picture. The reason for this is that the speaker may open other documents, web pages, and the like at the same time in the desktop sharing process, and the speaker may reduce the page areas of the other documents and web pages that are opened at the same time, that is, the occlusion of the real shared document is artificially reduced, at this time, although two adjacent desktop image data satisfy the similarity determination condition, the desktop image data in the occluded state still has the possibility that part of the key data is occluded. According to the practical situation, the desktop image data placed on the top layer of the screen is determined to be the historical key frame candidate picture, obviously, the document placed on the top layer of the screen cannot be shielded by other documents, webpages and other interfaces, so that the scheme of the application perfectly solves the problems and remarkably improves the review effect of the user.
Optionally, the calculating historical key frame candidate pictures for the cached desktop image data according to a predetermined algorithm further includes:
counting the operated data of the desktop image data corresponding to the historical key frame candidate pictures in the desktop sharing process, and processing the historical key frame candidate pictures with higher operated data in front of the sequence.
In the embodiment of the application, during the desktop sharing process, the user can operate the shared content on the participant terminal device, for example, zooming in and zooming out, and the operation reflects the interest degree of the user in the page content. According to the operation habit of the user, the server is arranged to sort the historical key frame candidate pictures with higher operated data in front, so that the key frame called out in response to the user interface action can meet the real review requirement of the user at the maximum probability.
Optionally, the shared desktop of the presenter is no longer displayed when the target image data is presented.
In the embodiment of the application, because the participant terminal device is usually a mobile terminal such as a mobile phone and a tablet, and the screen size of the participant terminal device is limited, in order to ensure the review effect of the user, the application sets that the shared desktop of the speaker is not displayed any more when the target image data is displayed, that is, only the historical key frame candidate pictures reviewed by the user are displayed. Of course, the shared desktop of the speaker and the historical key frame candidate pictures of the speaker that the user needs to review can be simultaneously displayed, only the screen interface needs to be reasonably divided, and the method and the device are particularly suitable for large-size terminal devices such as computers and large-screen tablet computers.
Optionally, a reverse interface action may also be included to enable a return from the review interface to the live sharing desktop of the presenter.
In the embodiment of the application, corresponding to the interface action for triggering review, the technical scheme of the application also sets a reverse interface action, namely, after the user enters the review interface, the user can exit the review interface through the reverse interface action, so that the user can conveniently and rapidly continue the progress of the video conference. For the specific setting of the reverse interface action, obviously, it may be set as a reverse operation action from the forward interface action, for example, a left-to-right sliding is set as the forward interface action, and a right-to-left sliding is set as the reverse interface action; of course, any other operation actions different from the forward interface action may be possible, and the present application is not limited to this.
