Detailed Description
The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that any combination of the embodiments or technical features described below can be used to form a new embodiment without conflict.
Example one
The embodiment provides a method for sharing a screen of multiple conference devices, wherein the multiple conference devices at least comprise a main device and at least one secondary device connected with the main device, and the main device and the secondary device are both connected with the same wireless network; the main device and the secondary device are connected with a cloud platform through a wireless network, and a plurality of storage spaces are arranged in the cloud platform. In this embodiment, the primary device and the secondary device are the same in terms of hardware, and content displayed on a screen of the primary device may be shared to a screen of the secondary device for display; the secondary device may also share the content displayed on the screen thereof to the primary device for display in the same manner, and this embodiment does not limit the sharing transmission direction.
As shown in fig. 1, in this embodiment, the method for sharing a screen between the primary device and the secondary device includes:
step S1: receiving a sharing instruction, dividing the screen display content of the main equipment into at least a basic layer and an active layer, respectively sending the basic layer and the active layer to different storage spaces for storage, and generating corresponding indexes.
The main equipment is provided with a sharing key, a conference manager presses the sharing key to generate a sharing instruction, and the content displayed on the current screen of the main equipment is divided according to the sharing instruction; at the moment, whether the screen picture of the main equipment enters an annotation state is judged, if the main equipment starts an annotation function, a user can add manual annotation in the content displayed on the screen of the main equipment, and at the moment, the screen display content of the main equipment is divided into a basic layer, a movable layer and a special effect layer when screen sharing is carried out; and if the current screen of the main equipment is only used for displaying the content and the annotating function is not started, dividing the screen display content of the main equipment into a basic layer and an active layer. Wherein the base layer is a background image displayed on a screen of the host device, such as: if the screen of the main equipment is displaying any page in the document, the picture of the document page displayed by the main equipment is a basic layer; if the main equipment screen stays on an equipment main page, a picture presented by the main page is a basic layer; i.e. the base layer is the static picture displayed on the main device. Whether a background image which is the longest of the current screen of the main equipment has dynamic animation or not is judged while the basic layer is generated, if yes, the animation is downloaded and stored into a storage space, and then a corresponding URL address is generated according to the storage position of the animation; when the secondary equipment displays the basic layer, pushing the URL address corresponding to the animation to the secondary equipment in a pop-up window mode, enabling a user to select whether the animation is displayed or not according to requirements, and if the animation needs to be displayed, clicking the URL address to enter a storage space to check the corresponding animation content; in addition, the URL address link is mapped in the area corresponding to the animation in the basic layer, when the user clicks the animation area of the basic layer, the URL address is triggered to display the animation in the storage space in the area where the animation is located in the basic layer, and therefore the content displayed by the secondary device and the content displayed by the main device are kept close to each other in picture distribution.
The active layer is a cursor movement track image formed by cursor movement on the screen of the main device, the cursor image is collected on the main device every preset time, and when the collection time is frequent and the collection quantity is large, the cursor image is overlapped to form the track image of the cursor movement. The cursor movement track image of the movable layer mainly comprises a background image layer with zero transparency and a track image layer with cursor movement, and the two image layers are overlapped to form a track image. The background layer with zero transparency can ensure that the image content of the basic layer can not be covered by the background layer of the active layer after the active layer is superposed on the basic layer.
The special effect layer is an image generated by the main device executing special effect processing, wherein the special effect processing executed by the main device comprises but is not limited to character annotation, doodle, paster and the like; when the main equipment enters the annotation state, a user can write by hand or input a character annotation on the main equipment, a painting brush can be used for drawing a graffiti, some effects such as stickers can be added, and an image generated through special effect processing is a special effect layer. The special effect layer mainly comprises a background layer with zero transparency and a special effect layer, and the two layers are superposed to form the special effect layer.
When the screen display content of the main equipment is divided into the basic layer and the active layer, or the basic layer, the active layer and the special effect layer, different layers are respectively sent to different storage spaces in a storage platform for storage; the division of the main equipment can be refreshed according to a fixed frequency, and a new base layer, a new active layer and a new special effect layer are generated after each refreshing; in addition, the refresh frequency among the base layer, the active layer and the special effect layer may be different, the refresh frequency of the base layer may be determined according to the replacement frequency of the background image displayed by the primary device, that is, when the background image displayed by the primary device is replaced, the base layer is refreshed to form a new base layer and then uploaded to the corresponding storage space for storage, and when the background image displayed by the primary device is not replaced and remains in the original state, the base layer is not refreshed, so that the original base layer is still displayed on the secondary device; the active layer and the special effect layer can be refreshed according to a preset frequency so as to ensure that the shared cursor and the shared special effect have a coherent display effect.
Before uploading the base layer, the active layer and the special effect layer to different storage spaces, relevance coding needs to be carried out on the base layer, the active layer and the special effect layer, each layer is uploaded after coding is finished, and corresponding indexes are generated according to coding, so that corresponding contents can be found from the storage spaces quickly. If the refresh frequency of the base layer, the active layer and the special effect layer is the same, the coding can be carried out according to the refresh time, namely, every time the base layer, the active layer and the special effect layer are refreshed, the codes of the base layer, the active layer and the special effect layer generated by refreshing are set to be 1001, 1002 and 1003, the meaning of the first letter in the codes is the refresh frequency, the meaning of the last letter is the type of the surface layer, three-layer stacking can be carried out according to the last letter, and errors in the stacking sequence can be avoided. When the refresh frequencies of the base layer, the active layer and the special effect layer are different, the refresh time of the base layer can be used as a coding basis, for example: in the time when the base layer maintains the original image, the encoding of the base layer is 1001, and a new active layer generated by refreshing the active layer for multiple times can be encoded by numbers such as 1012, 1022, 1032, and the like, and similarly, the special effect layer can be encoded by numbers such as 1013, 1023, 1033 and the like; when the base layer is refreshed, the encoding of the base layer is 2001, and a new active layer generated by the active layer performing multiple refreshes may be encoded by numbers 2012, 2022, 2032, and the like, and similarly, the special effect layer may be encoded by numbers 2013, 2023, 2033, and the like. The base layer, the active layer and the special effects layer are associated by using the codes. Since the number of refreshes is large, the specific rule of encoding may be complicated, and the present embodiment establishes the encoding of the base layer, the active layer, and the special effect layer as 1001, 1002, 1003, and the like for explanation reference only.
Step S2: and extracting the corresponding basic layer and the corresponding active layer from a storage space according to the index, synthesizing the basic layer and the active layer, and sending the synthesized image to the secondary equipment for displaying.
Different storage spaces in the cloud platform are respectively used for storing a base layer, an active layer and a special effect layer which are generated in each refreshing, the base layer, the active layer and the special effect layer all have own codes, corresponding indexes are generated according to the codes, the corresponding base layer, the corresponding active layer and the corresponding special effect layer are extracted from the storage spaces through the indexes, and then the base layer, the active layer and the corresponding special effect layer can be sequentially synthesized. In this embodiment, the sizes of the background layers of the active layer and the special effect layer are the same as the size of the basic layer, and the size of the basic layer is the same as the display size of the screen of the main device, so that the positions of the cursor and the special effect displayed on the secondary device on the basic layer after three layers are superposed are the same as the positions of the cursor and the special effect displayed on the screen of the main device, and the influence of too large offset generated by the cursor and the special effect on the display effect when the secondary device displays is avoided.
During synthesis, extracting a base layer, an active layer and a special effect layer which are associated according to an index and sequentially superposing the base layer, the active layer and the special effect layer, for example, under the condition that the refresh frequencies of the base layer, the active layer and the special effect layer in the above example are the same, extracting layers coded by 1001, 1002 and 1003 to obtain the base layer, the active layer and the special effect layer which are generated after first refresh, sequentially superposing the layers, and sending superposed images to the secondary equipment for display; in the above example, when the refresh frequencies of the base layer, the active layer, and the special effect layer are different, the layers coded by 1001, 1012, and 1013 are extracted to obtain the layer generated by the first refresh of the active layer and the special effect layer when the base layer is not changed, and the layers are sequentially superimposed, and the superimposed image is sent to the secondary device for display; then, the layers coded by 1001, 1022 and 1023 are extracted to obtain the layers generated by second refreshing of the active layer and the special effect layer under the condition that the base layer is not changed, the layers are sequentially superposed, namely the base layer is positioned at the bottom of the layers when the base layer, the active layer and the special effect layer are synthesized, the active layer and the special effect layer are sequentially superposed above the base layer, and the superposed images are sent to the secondary equipment for displaying.
In the embodiment, the pictures displayed by the current screen of the main device are separately uploaded to the cloud, so that the uploading speed can be increased, and under the condition of increasing the uploading speed, the situation that the uploading efficiency is increased by compressing the images in the transmission process can be avoided, and the definition of the transmitted images is ensured; meanwhile, the multi-layer content is stored in different storage spaces of the cloud, so that the phenomenon that the multi-layer content occupies too much local space of the main equipment can be avoided, the running stability of the equipment is improved, and the situations of blocking, delay and the like of the shared content are reduced.
