In this specification, the schematic representations of the terms used above do not necessarily refer to the same embodiment or example. Furthermore, the particular features or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.
Referring to fig. 1, the present embodiment discloses a screen sharing method for multiple conference devices based on a hong meng system, and in the present embodiment, the method is suitable for an all-in-one machine carrying the hong meng system, and preferably, a participating device such as a mobile phone or a computer can also carry the hong meng system, and the method includes the following steps:
and 101, establishing connection with the conference all-in-one machine. In this embodiment, conference software is configured on both the conference all-in-one machine and the terminals participating in the conference.
And 102, acquiring a current picture transmission mode. Generally, the screen transmission mode may include a local mode, and the screen projection may be implemented by a dedicated screen projection device. In the remote mode, the scheme comprises a normal mode and a throttling mode, wherein the throttling mode comprises a local throttling mode (a mode for solving the problem mainly) and a global throttling mode. The global throttling mode is to reduce the overall quality of the picture, and the local throttling mode is to reduce the local quality of the picture.
And 103, when the current picture transmission mode is the local throttling mode, displaying a screen projection selection frame, and adjusting the position and the size of the area of the screen projection selection frame according to the acquired input instruction. In this step, the user can make a selection according to the importance of the content. For example, the shared screen is a word document, for which the toolbar or both sides of the document may not be the focus of the transmission, but the body of the word document.
And 104, processing and transmitting the currently displayed picture, wherein the picture of the selected area of the screen-casting selection frame is processed by using a first standard, the picture of the unselected area of the screen-casting selection frame is processed by using a second standard, and the picture quality of the picture processed by the first standard after being restored is higher than the picture quality of the picture processed by the second standard after being restored.
In this step, the pictures are actually processed according to the areas selected by the user and the areas not selected by the user, and although the processing steps increase the computation of the local device and the all-in-one machine, the processed video stream can be compressed.
And picture quality may be reflected by frame rate, resolution and video compression rate. Taking the frame rate as an example, for the unselected area, the frame may be extracted at certain intervals, for example, the even frames are extracted and replaced with the previous frame, so that the actual number of frames does not change. But the actual frame rate is half the original. And a greater proportion of compression will be achieved when compressed. Taking resolution reduction as an example, the proportion of the picture is not compressed, but the resolution is compressed, and when the all-in-one machine is used for reduction, the corresponding picture is only stretched and reduced to the original proportion. Taking the compression rate improvement as an example, the higher the compression rate is, the more information is consumed by the general picture, and the high compression rate can improve the compression ratio and reduce the transmission bandwidth.
According to the method and the device, the screen projection selection frame which can be selected by the user is displayed according to the picture mode selected by the user, the user can select the key area in a frame mode, a higher-quality picture processing mode is adopted for the key area, a processing mode for reducing the picture quality is selected for the non-frame-selected area, and unimportant information can be compressed in a larger proportion through the mode, so that the requirement on bandwidth is reduced, and when bandwidth resources are not enough to maintain the fluency of a standard picture, the fluency and the definition of the key picture area are selectively maintained.
In some embodiments, a frame rate of pictures processed by the first standard is higher than a frame rate of pictures processed by the second standard;
and/or
The compression rate of the picture processed by the first standard is less than the compression rate of the picture processed by the second standard;
and/or
The resolution of the picture processed by the first criterion is greater than the resolution of the picture processed by the second criterion.
As can be seen from this embodiment, when the picture frame rate processed by the second standard is lower, the compression rate is higher, and the resolution is lower, the restored picture quality is definitely inferior to the picture quality processed by the first standard.
In some embodiments, further comprising the steps of:
detecting a transmission bandwidth between the conference all-in-one machine;
when the transmission bandwidth between the conference all-in-one machine is smaller than a first threshold value;
the user is prompted to select a picture mode, wherein the picture mode includes a local throttle mode and a global throttle mode.
In some embodiments, the transmission bandwidth between the screen sharing device and the all-in-one machine is detected through a bandwidth test, and when the bandwidth is sufficient, a user does not need to be reminded to start a throttling mode. And when the bandwidth is obviously insufficient to transmit the full screen with high quality, prompting the user to select. A selection button may be displayed for selection by the user.
In some embodiments, the processing, by using the first criterion, the picture of the selected area of the screen-casting selection box, and the processing, by using the second criterion, the picture of the unselected area of the screen-casting selection box specifically include:
acquiring each frame of picture and processing each frame of picture, wherein the picture of the area selected by the screen-casting selection frame is taken as a first video stream and the picture of the area not selected by the screen-casting selection frame is taken as a second video stream during processing, and the area selected by the screen-casting selection frame is filled with a set color during processing; processing the first video stream using a first criterion; processing the second video stream using a second criterion.
In the present embodiment, the video is divided into two video streams for processing, but the two video streams may be combined in chronological order at the time of transmission. And the assembly can be done locally or in an all-in-one machine. For example, the two video streams may be reassembled before transmission and then transmitted, or the two video streams may be combined according to time and then transmitted to the unified device, and then the unified device reassembles and restores the picture.
In some embodiments, a higher retransmission priority is configured for a first video stream when the first video stream and a second video stream are transmitted. In this embodiment, in some cases, information needs to be retransmitted, and the priority of content retransmission corresponding to the first video stream is higher.
In some embodiments, the second standard is determined according to a transmission bandwidth between the current conference kiosk and the conference kiosk, and when the current transmission bandwidth is smaller than a second threshold, the compression rate in the second standard is increased, the resolution in the second standard is decreased, or the frame rate in the second standard is decreased, where the second threshold is smaller than the first threshold. In some embodiments, when the current transmission bandwidth is greater than a third threshold, the compression rate, resolution and frame rate in the second standard are restored to the default values of the second standard, the third threshold being less than the first threshold and greater than the second threshold.
In the above embodiment, the resolution, the frame rate, and the compression rate in the second standard are processed according to the bandwidth, and in this embodiment, a plurality of levels are set for the second standard, and the lower the bandwidth, the lower the picture quality corresponding to the second standard. By dynamically adjusting the second standard, the fluency and the definition of the picture of the area selected by the user can be further ensured.
