Description

Technical Field

[0001] The present invention relates to the field of cloud computing technology, and in particular to a desktop protocol regional streaming method, a desktop protocol server, a desktop protocol system, a storage medium and a computer program product. Background Art

[0002] In the virtualized desktop protocol, the protocol server determines whether multiple consecutive images are video data by detecting whether the width and height of 23 consecutive images generated within a certain period of time are equal, and whether the target areas for image drawing are the same. If the width and height of the above 23 images are equal, and the target areas for image drawing are the same, the protocol server will consider that the target areas for drawing the 23 images can become the target areas for regional streaming, and thus perform regional streaming. When new images are subsequently generated, when the new image drawing area is in the target area for regional streaming, the protocol server encodes the image data using mjpeg and sends the image data to the protocol client. However, this method has the following problems:

[0003] 1. When the player is playing a video, if it moves or the window size is slightly adjusted, it will cause the area to be exited and the streaming and area streaming operations will need to be performed again.

[0004] 2. When the browser plays a video, the area position will continuously shift by several pixels, causing the browser video to frequently exit the area flow and the area flow.

[0005] 3. When playing video in a window, if the window is continuously moved before entering the regional stream, the local stream cannot be detected.

[0006] The above scenarios will cause frequent exit of regional streams. At the same time, in the process of detecting incoming streams, a large number of images are compressed losslessly, resulting in an increase in bandwidth peaks and consumption of a large amount of network bandwidth, thereby reducing user experience under certain bandwidth resources. Summary of the invention

[0007] In order to solve the technical problem that the existing desktop protocol regional streaming method will cause frequent exit of regional streaming and consume a large amount of network bandwidth, the embodiments of the present invention provide a desktop protocol regional streaming method, a desktop protocol server, a desktop protocol system, a storage medium and a computer program product.

After regional streaming is performed, the method further includes: when the desktop protocol server generates new image data, determining whether the target area for drawing the new image data is within the target area for regional streaming; when determining that the target area for drawing the new image data is within the target area for regional streaming, adding the new image data to a queue of image data to be subjected to regional streaming.

[0014] In one embodiment, performing regional streaming includes: organizing data through a regional streaming structure, encoding the image data to be regionally streamed using jpeg2000, and then sending the encoded data to be regionally streamed to a desktop protocol client.

[0023] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0024] The embodiment of the present invention provides a desktop protocol area streaming method, such as Figure 1 As shown, the method includes:

[0025] Step 101: Acquire multiple image data generated by the desktop protocol server;

[0026] Step 102: determining whether the plurality of picture data are associated and whether the target areas drawn by the plurality of picture data are associated;

[0027] Step 103: When it is determined that the plurality of image data are associated and the target areas drawn by the plurality of image data are also associated, a union of the target areas drawn by the plurality of image data is used as the target area for regional flow formation, and regional flow formation is performed.

[0028] This embodiment improves the judgment conditions for regional streaming of the desktop protocol server. It is no longer necessary to detect whether the width and height of 23 pictures are equal within a certain period of time. The target area for picture drawing must be completely consistent before the pictures can be used as video data. Instead, the picture data generated by the desktop protocol server is analyzed to analyze whether the newly generated picture data has the relevance of the picture data and the relevance of the target area for picture drawing. When the newly generated picture data and the target area for picture drawing are related, the union of the target areas drawn by the newly generated multiple picture data is used as the target area for regional streaming, and regional streaming is performed. This embodiment saves the detection time for regional streaming, reduces the bandwidth peak during regional streaming, and improves the user experience.

[0029] Specifically, the present embodiment can determine whether the multiple picture data are associated and whether the target areas drawn by the multiple picture data are associated in the following manner: obtain the image size data, color histogram and drawn target area of ​​each picture data in the multiple picture data; and use the image size data, color histogram and drawn target area of ​​each picture data as the picture feature information of each picture data; use the histogram intersection method to calculate the similarity between the picture feature information of each picture data in the multiple picture data and the picture feature information of each other picture data; when the similarity is greater than a preset similarity threshold, determine that the two calculated picture data are associated and the target areas drawn by the two picture data are also associated; obtain the similarity calculation result between all the picture data and each other picture data; and determine whether the multiple picture data are associated and whether the target areas drawn by the multiple picture data are associated based on the similarity calculation result.

[0030] By detecting the similarity of image feature information to determine whether the image data is relevant and whether the target area drawn by the image data is relevant, the technical problem of frequent exit from the area flow caused by the original harsh flow judgment conditions and the presence of a few more pixels in the image can be solved.

[0031] According to the similarity calculation result, the number of picture data with correlation and the number of picture data with correlation in the target area drawn by the picture data can be counted; when the number of the picture data is greater than a preset number, the union of the target areas drawn by the preset number of picture data is used as the target area for regional flow, and regional flow is performed.

[0032] Here, the preset number may be 8 sheets.

[0033] In addition, when the desktop protocol server generates new image data, it determines whether the target area for drawing the new image data is within the target area for regional streaming; when it is determined that the target area for drawing the new image data is within the target area for regional streaming, the new image data is included in the image data queue to be regionally streamed.

[0034] Here, when performing regional streaming, data can be organized through the regional streaming structure, and the image data to be regionally streamed can be encoded using jpeg2000 and then sent to the desktop protocol client.

[0035] This embodiment accumulates the count of waiting streams. When the count of waiting streams reaches 8 pictures within a certain period of time, the union of the target drawing areas of the 8 pictures is used as the target area for regional streaming. When the regional streaming area of ​​the newly generated pictures contains the target drawing area of ​​the pictures, the protocol server uses jpeg2000 to encode the picture data, and the picture data is organized and sent in the form of regional streaming. The use of such picture data relevance and picture drawing target area relevance solves the problems of the original harsh streaming judgment conditions, the frequent exit of regional streaming, detection of regional streaming, and regional streaming caused by a few more pixels in the picture. It saves the detection time of regional streaming. Based only on 8 picture data, the bandwidth peak during regional streaming can be reduced to improve the experience. The encoding adopts the jpeg2000 encoding method to reduce the bandwidth of video playback to a greater extent, thereby improving the user experience under certain bandwidth resources.

[0036] Specifically, see Figure 2This embodiment proposes a method for judging the image data and the image drawing target area of ​​the image generated by the server on the virtual desktop protocol server. First, the image feature information is generated by measuring the size and color of the input image and the image drawing target area, and the feature information of the image is put into the prepared stream image queue of the server. When the protocol server generates a new picture data, it first obtains the recorded picture feature information from the queue of prepared streaming pictures maintained by the protocol server, including image size data, color histogram, and picture drawing target area. Then, it performs the same feature extraction on the current newly generated picture, calculates the difference between the two sets of feature information, uses the histogram intersection method to evaluate the similarity, sets a similarity threshold, and determines whether the similarity between the new picture and the recorded picture exceeds the threshold. If it exceeds, it is considered that the two pictures are associated in the picture data and the picture drawing target area, and the associated pictures are used as streaming pictures. At the same time, for streaming pictures, when the protocol server continuously detects 8 such associated picture data within a certain period of time, the union area composed of the drawing target areas of these 8 associated pictures is used as the target area of ​​regional streaming. When the protocol server generates new picture data later, when the target area of ​​regional streaming contains the picture drawing target area, the picture data is organized through the regional streaming structure, encoded using jpeg2000, and sent to the protocol client. By judging the relevance of images and the relevance of the target area of ​​image drawing, only eight such image data are needed, which can reduce the detection time of the stream and improve the user experience. This new method and system can effectively improve the efficiency and user experience of the virtualized desktop protocol, while reducing the consumption of network bandwidth.

[0037] The desktop protocol client uses jpeg2000 to decode the image data sent by the protocol server.

[0038] This embodiment scheme changes the judgment condition of the desktop protocol stream formation, and adopts the correlation of pictures and the correlation of the target area for drawing pictures. In this method, the original judgment that 23 pictures with the same width and height and the same target area for drawing pictures are generated within a certain period of time is changed to the correlation of picture data and the correlation of picture drawing target areas. Only 8 picture data are judged. As long as there is correlation, the count of pictures to be streamed is accumulated within a certain period of time. When the count of pictures to be streamed reaches 8 pictures, the union area composed of the target areas for drawing pictures to be streamed is used as the target area for streaming. The detection method of the correlation of picture data and the correlation of picture drawing target areas is used to speed up the time for streaming detection and reduce the bandwidth peak caused by the detection of the streams.

[0039] This embodiment mainly modifies the desktop protocol server. On the desktop protocol server, the image data relevance, image drawing target area relevance, and the queue of images to be streamed are mainly introduced. This improvement improves the efficiency and performance of the desktop protocol by optimizing the desktop protocol processing method, while also reducing the use of network bandwidth, providing a new and effective optimization technology for the use of cloud desktops.

[0040] This embodiment provides a method that can reduce the time consumption of the desktop protocol in detecting whether continuous images are used as video data in a cross-architecture, real-time manner when using a cloud desktop, and reduce the bandwidth peak caused by the detection itself due to the harsh detection conditions, frequent exit of regional streaming, detection of regional streaming, and entry of regional streaming. This method improves the efficiency and performance of the desktop protocol by optimizing the regional streaming processing method of the desktop protocol, while also reducing the use of network bandwidth, providing a new and effective optimization technology for the use of cloud desktops. The application of this technology can not only improve the user experience of the cloud desktop, but also reduce the use of network bandwidth, thereby saving network resources and improving network usage efficiency.

[0041] In order to implement the method of the embodiment of the present invention, the embodiment of the present invention further provides a desktop protocol server, which is used to obtain multiple generated image data; determine whether the multiple image data are associated and whether the target areas drawn by the multiple image data are associated; when it is determined that the multiple image data are associated and the target areas drawn by the multiple image data are also associated; use the union of the target areas drawn by the multiple image data as the target area for regional streaming, and perform regional streaming.

[0042] This embodiment uses the image data relevance and the image drawing target area relevance for the image data generated by the desktop server to put the image data with relevance within a certain period of time into the queue of images to be streamed on the desktop protocol server. When the desktop protocol server generates a new image data, firstly, the stored relevance image feature data is taken out from the queue of images to be streamed on the desktop protocol server, and compared with the newly generated image data. When the newly generated image information is associated with the images in the queue of images to be streamed, the count of the queue of images to be streamed is accumulated. When the count of the queue of images to be streamed reaches 8 images, the target drawing areas of these 8 associated images are combined into a set area as the target area of ​​regional streaming. When the target area of ​​the image drawing newly generated by the protocol server falls within the target area of ​​regional streaming, the protocol server encodes the image data using jpeg2000, organizes the data according to the logic of streaming data, and sends it to the protocol client. This embodiment speeds up the detection time of the streaming area, improves the efficiency and performance of the desktop protocol, and also reduces the peak value of network bandwidth caused by streaming detection, providing a new and effective desktop protocol optimization technology.
