Detailed Description
The core of the invention is to provide an output system of the video compression image, which can effectively output the video compression image and avoid the image tearing condition.
In order that those skilled in the art will better understand the disclosure, the invention will be described in further detail with reference to the accompanying drawings and specific embodiments. It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a schematic structural diagram of an output system of a video compressed image according to the present invention, the output system of the video compressed image may include:
a compression module 10, configured to, each time a frame of image data is compressed, place the compressed frame of image data into a buffer module 20;
a cache module 20;
a control module 30;
the data write-in controller 40 is configured to read a frame of image data from the buffer module 20 based on a first-in first-out rule whenever the BMC management module clears an interrupt signal, write the frame of image data into a preset memory area, and output an interrupt signal to the BMC management module through the control module 30, so that the BMC management module clears the interrupt signal after reading the frame of image data from the memory area; when the current interrupt signal is determined not to be cleared by the BMC management module and the duration exceeds a preset duration threshold, frame dropping is carried out according to a preset active frame dropping rule;
and the BMC management module is used for outputting each frame of image data read from the memory area.
Specifically, the display card in the server host can receive display information of the server host operating system, can form VGA data, display the VGA data locally in the server, and simultaneously, can store the VGA data in the memory according to a certain format, so that the remote end can obtain the VGA data through the ethernet network. And because the compression can reduce the amount of data transmitted by the ethernet network, a video compression module is usually arranged in the conventional BMC to read VGA data from a memory for compression, and the VGA data is stored in a corresponding area of the memory after compression, so that the compressed data stored in the memory can be transmitted to a remote end through the ethernet network for the remote end to display video.
In the solution of the present application, in addition to the compression module 10 being provided to reduce the amount of transmission data for subsequent data transmission in ethernet, a buffer module 20, a control module 30, and a data write controller 40 are also provided. In addition, the BMC management module is not shown in fig. 1 and 2 of the present application.
Since video compression is performed according to one-by-one image compression, each time a frame of image data is compressed, the compression module 10 puts the compressed frame of image data into the buffer module 20 provided in the present application. The compression module 10 may be specifically selected as, for example, the JPEG image compression module 10 in fig. 2.
The buffer module 20 of the present application may be selected as a FIFO (First Input First Output) type buffer module 20, and the size of the space of the buffer module 20 may also be set and adjusted according to actual needs, without affecting the implementation of the present invention, and of course, the size of the space may be set to a size capable of accommodating multi-frame image data.
When the compression module 10 puts the compressed image data of each frame into the cache module 20, the communication protocol based on which may also be selected according to needs, for example, the compressed image data of each frame may be sequentially put into the cache module 20 through an AHB (Advanced high performance Bus) interface in the embodiment of fig. 2.
Whether the BMC management module clears the currently existing interrupt signal may be detected by the data write controller 40 or by the control module 30, as long as the function of the present application can be implemented. For example, when the data write controller 40 determines that the BMC management module clears the currently existing interrupt signal, the information may be sent to the control module 30, and the control module 30 may further output a trigger signal to the data write controller 40, that is, each time the data write controller 40 receives a trigger signal, one frame of image data may be read from the buffer module 20 and written into the preset memory area. For another example, the control module 30 determines whether the BMC management module clears the currently existing interrupt signal, if it determines that the currently existing interrupt signal is cleared, the control module 30 may output a trigger signal to the data write-in controller 40, and each time the data write-in controller 40 receives a trigger signal, the data write-in controller may read out a frame of image data from the buffer module 20 and write the frame of image data into the preset memory area.
When the data write controller 40 writes the image data into the preset memory area, the communication protocol based on may also be selected as needed, for example, considering that the AXI bus has a higher data transmission rate, so in an embodiment of the present invention, the data write controller 40 may be the data write controller 40 that performs the write operation based on the AXI (Advanced eXtensible Interface) bus. For example, in fig. 2, the data write controller 40 of the present application may be specifically selected as AXI Master.
It should be noted that, when the AXI bus is selected to implement the data write controller 40 of the present application, since the data amount written by the data write controller 40 at each time is fixed, the data write controller 40 writes the frame of image data read from the buffer module 20 into a preset memory area, and multiple write operations may need to be performed. For example, if the image data size of a certain frame is 20 bits, the data write controller 40 assumes that 16-bit data is fixedly written each time, it is necessary to write twice for the image data of the present frame, and the insufficient number of bits can be filled by complementing 0 at the time of writing the second time.
After the data write controller 40 writes the complete frame of image data into the preset memory region, it can output an interrupt signal to the BMC management module through the control module 30, and the BMC management module clears the interrupt signal after reading the frame of image data from the memory region. It is understood that, when the output system of the video compressed image is operating normally, the BMC management module clears the interrupt signal in time, so that the data write controller 40 can continue to write the next frame of image data into the predetermined memory area, and then generates the interrupt signal, and so on.
The preset memory region may be set by a worker, for example, an instruction for setting the memory region is output to the control module 30 through an APB (advanced peripheral Bus) interface, where the instruction may carry a start address and a size of the memory, so as to limit an address range of the memory region when the data write controller 40 performs a write operation. The data writing controller 40 writes the image data of each frame into the preset memory area by performing the writing operation in a sequential writing manner or a cyclic writing manner, which is also a more common data writing manner.
As described above, when the output system of the video compressed image normally operates, the BMC management module may timely clear the interrupt signal, and if the BMC management module does not timely clear the interrupt signal, for example, some abnormal conditions cause the BMC management module to not timely clear the interrupt signal, if the active frame dropping operation of the present application is not performed, it can be understood that the data write controller 40 will not continuously write the image data into the memory, and the compression module 10 will continuously generate the image data and place the image data into the buffer module 20, and when the buffer module 20 is full, a part of data content of a certain frame is easily stored in the buffer module 20, and another part of the data content is not stored, and then the image will be torn.
Therefore, in the scheme of the application, when it is determined that the currently existing interrupt signal is not cleared by the BMC management module and the duration exceeds the preset duration threshold, it can be determined that the output system of the video compressed image is blocked, and frame dropping can be performed according to the preset active frame dropping rule. The preset active frame dropping rule can be set according to actual needs, but when dropping, complete one or more frames of data need to be dropped to avoid the situation of image tearing.
For example, in an embodiment of the present invention, the preset active frame dropping rule is:
reading a frame of image data from the buffer module 20 based on a first-in first-out rule, discarding the frame of image data after reading the frame of image data, judging whether the BMC management module clears the currently existing interrupt signal after discarding the frame of image data, if so, ending the frame-missing process, otherwise, returning to execute the operation of reading a frame of image data from the buffer module 20 and discarding the frame of image data until the BMC management module clears the currently existing interrupt signal.
In this embodiment, as long as it is determined that the currently existing interrupt signal is not cleared by the BMC management module and the duration exceeds the preset duration threshold, the data write controller 40 starts to drop frames. Specifically, the data write controller 40 reads out a frame of image data from the buffer module 20 based on the first-in first-out rule, and discards the frame of image data after reading. Then, it can be determined whether the BMC management module clears the currently existing interrupt signal, if not, a frame is discarded, and then it is determined whether the interrupt signal is cleared, and so on. Until the current interrupt signal is cleared, the frame loss process is finished. That is, when it is determined that the current interrupt signal is cleared, the data write controller 40 may read out one frame of image data from the buffer module 20 and write the frame of image data into the preset memory area, and then output an interrupt signal to the BMC management module through the control module 30.
In a specific embodiment of the present invention, the preset active frame dropping rule is:
when the remaining available space of the cache module 20 is judged to be lower than the preset space threshold, reading a frame of image data from the cache module 20 based on a first-in first-out rule, discarding the frame of image data after reading, judging whether the BMC management module clears the currently existing interrupt signal after discarding, if so, ending the frame-missing process, otherwise, returning to execute the operation of reading a frame of image data from the cache module 20 and discarding the frame of image data until the BMC management module clears the currently existing interrupt signal.
Considering that the buffer module 20 has a certain capability of storing image data, after it is determined that the currently existing interrupt signal is not cleared by the BMC management module and the duration exceeds the preset duration threshold, in this embodiment, the frame dropping operation is not performed immediately, but the frame dropping operation is performed only when the remaining available space of the buffer module 20 is lower than the preset space threshold, so as to fully utilize the storage capability of the buffer module 20. The value of the spatial threshold may be set and adjusted according to actual needs, but is usually set to a value larger than the size of one frame of image data. In addition, in this embodiment, the operation of determining whether the remaining available space of the cache module 20 is lower than the preset space threshold may be implemented by the control module 30, or may be implemented by the data write controller 40, without affecting the implementation of the present invention, for example, in the embodiment of fig. 2, the control module 30 may determine whether the remaining available space of the cache module 20 is lower than the preset space threshold.
Further, in an embodiment of the present invention, the data writing controller 40 may further be configured to:
after writing any frame of image data into the preset memory area, the frame header start-stop address of the frame of image data and the size of the frame of image data are sent to the BMC management module through the control module 30.
In this embodiment, the BMC management module needs to know the start position and the end position of each frame image in the memory area, considering that the BMC management module needs to send each frame image in the memory area to the remote end through the ethernet. For each frame of image data, the BMC management module may determine the start position and the end position of the frame of image by detecting the frame head flag and the frame tail flag of the frame of image. In this embodiment, considering that the BMC management module determines the start position and the end position of the frame of image, the time consumed by the BMC management module to clear the interrupt signal may be increased, and it is also not beneficial to send the image data to the remote end in time, so that the data write controller 40 obtains the start and stop address of the frame header of the frame of image data and the size of the frame of image data after writing any frame of image data into the preset memory area, and sends the frame of image data to the BMC management module through the control module 30, which reduces the workload of the BMC management module, and is also beneficial to improving the work efficiency of the output system of the video compressed image of the present application.
The implementation method has more obvious effect particularly in the situation that the BMC management module is busy.
When writing any frame of image data into a preset memory area, the data write controller 40 may determine the head of the frame according to the frame head flag, determine the tail of the frame according to the frame tail flag, start counting from the frame head flag of the frame through a counter provided in the data write controller 40 until the frame tail flag is detected, and stop counting, so as to obtain the size of the image data of the current frame. Since the data write controller 40 performs the write operation in a sequential write mode or a cyclic write mode, the data write controller 40 can also know the frame header start/stop address for writing the frame of image data into the memory area.
In addition, since the data write controller 40 needs to send an interrupt signal to the BMC management module through the control module 30, in this embodiment, the frame header start/stop address of the frame image data, the size of the frame image data, and the interrupt signal may be sent together. Of course, each frame of image data described in the present application refers to image data compressed by the compression module 10.
By applying the technical scheme provided by the embodiment of the invention, the blocking is prevented by actively dropping frames, thereby avoiding the situation of image tearing. Specifically, each time the BMC management module clears the primary interrupt signal, the data write controller 40 may read a frame of image data from the buffer module 20 based on a first-in first-out rule, write the frame of image data into the preset memory area, and output the primary interrupt signal to the BMC management module through the control module 30. Therefore, if the output system of the video compressed image of the present application operates normally, after the BMC management module reads the frame of image data from the memory area, the interrupt signal may be cleared in time, so that the data write controller 40 may write the next frame into the memory. Correspondingly, if it is determined that the currently existing interrupt signal is not cleared by the BMC management module and the duration exceeds the preset duration threshold, it is described that the current output of the video compressed image is blocked, so that the present application drops frames according to the preset active frame dropping rule. In conclusion, the scheme of the application can effectively output the video compression image, and avoids the situation of image tearing.
Corresponding to the above system embodiments, the embodiments of the present invention further provide an output method of video compressed images, which can be referred to in correspondence with the above.

step S103: when the current interrupt signal is determined not to be cleared by the BMC management module and the duration exceeds a preset duration threshold, the data write-in controller performs frame loss according to a preset active frame loss rule;
step S104: and the BMC management module outputs each frame of image data read from the memory area.
