Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. 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.
[ first embodiment ] A method for manufacturing a semiconductor device
As shown in fig. 1, a video source processing method according to a first embodiment of the present invention includes:
s11: acquiring at least one input video source;
s13: decoding the at least one input video source to obtain a number of video sources;
s15: determining the layout of splicing windows according to the number of the video sources;
s17: and splicing the at least one input video source according to the layout of the splicing window to obtain a spliced video source.
As shown in fig. 2, in another specific implementation manner, the video source processing method of this embodiment further includes:
s18 a: responding to the change of the number of the video sources, and changing the layout of the splicing window according to the changed number of the video sources to obtain the changed layout of the splicing window;
s18 b: and splicing the at least one input video source according to the changed splicing window layout.
As shown in fig. 3, in a further specific implementation manner, the video source processing method of this embodiment further includes:
s19: and carrying out scaling processing on the spliced video source to obtain a video source with a target resolution as output.
In order to more clearly understand the present embodiment, the following will illustrate the video source processing method of the present embodiment in detail with reference to fig. 4A, 4B, 5A and 5B.
Specifically, the video source processing method of this embodiment may specifically be a multi-video source decoding automatic stitching processing method, and the automatic stitching processing method may be widely applied to a plurality of different fields, and not only to the field of video processing stitching display.
As shown in fig. 4A, the left video source portion may be a web camera, streaming media server, or other video source; the video processing device 40 has video source decoding, splicing and output functions; the right part is a rear-stage display system, which is not limited to being a rear-stage video processing display system or display.
As mentioned above, the video processing device 40 is connected to the left video source part through a switch network communication connection or other connection method, for example, and it is only necessary that the video processing device 40 can normally acquire the video source. When four video source splicing processing needs to be realized, four video sources VS1-VS4 of the left video source part are accessed to the video processing device 40, then the video processing device 40 decodes the video sources VS1-VS4, determines a splicing window layout (for example, a 2 × 2 splicing window layout shown in fig. 4A, corresponding to four splicing windows) according to the number of the decoded video sources, performs automatic splicing processing to obtain spliced video sources, and then outputs the spliced video sources for a rear-stage display system to use according to a set or automatic resolution; this process does not require the number of stitching windows to be set in advance for the video processing apparatus 40. It is worth mentioning that, for the spliced video source obtained by the splicing processing, the spliced video source can be directly output according to the actual resolution of the spliced video source, and can also be output after being scaled according to the actual requirement.
Referring to fig. 4B, when the number of video sources in the left video source portion is increased to eight, the eight video sources VS1-VS8 in the left video source portion are accessed to the video processing device 40, and then the video processing device 40 performs decoding on the video sources VS1-VS8, determines a splicing window layout according to the number of video sources solved (for example, the 2 × 4 splicing window layout shown in fig. 4B corresponds to eight splicing windows), performs automatic splicing processing to obtain spliced video sources, and then outputs the spliced video sources for use by a subsequent display system according to a set or automatic resolution; this process does not require the user to reconfigure the number of stitching windows of the video processing device 40 and is not limited to four of the eight video sources VS1-VS8 for stitching output.
Therefore, the video processing device 40 of the present embodiment can continuously detect the change of the number of the input video sources, and when an input video source is newly added, the input video source can be dynamically re-spliced and output in an optimal splicing manner in time for the subsequent display system to use. It will be appreciated that it is of course also possible to re-stitch dynamically for situations where the input video source is reduced. Furthermore, it should be noted that the present embodiment does not limit the number of input video sources, the output resolution size, and the number and resolution of the stitching windows, and the limit mainly depends on the performance impact of the video processing apparatus 40. In addition, for the mosaic window layout, a mapping relation table between the number of video sources and the mosaic window layout may be preset on the video processing device 40, or a mosaic window layout may be immediately created based on the detected number of video sources by using a window layout function, which is not specifically limited herein.
In addition, referring to fig. 5A, the video processing apparatus 40 of the present embodiment includes, for example, an ethernet interface circuit 51 and an embedded processor 53 electrically connected to the ethernet interface circuit 51, wherein the ethernet interface circuit 51 is adapted as an input interface circuit for inputting at least one video source described in the foregoing step S11, and the embedded processor 53 is adapted to execute the foregoing steps S11, S13, S15 and S17, and even execute the foregoing steps S18a and S18b, and/or S19. As an example, as shown in fig. 5B, the ethernet interface circuit 51 includes two network ports 511a and 511B and two ethernet physical layer transceivers 513a and 513B, wherein the network port 511a is electrically connected to the ethernet physical layer transceiver 513a, the network port 511B is electrically connected to the ethernet physical layer transceiver 513B, and preferably the network ports 511a and 511B share a network transformer to form electrical connections with the ethernet physical layer transceivers 513a and 513B, respectively. In this case, a single internet access can receive a plurality of streaming media sources (corresponding to a plurality of input video sources), so that the number of video source input interfaces can be reduced to a greater extent. Furthermore, the video source output by the embedded processor 53, such as the stitched video source or the scaled stitched video source, may be output to the programmable logic device 55 for post-processing (such as clipping, rescaling, overlay stacking, etc.), and then provided to the back-end display system by the programmable logic device 55.
In summary, the video source processing method of the embodiment can automatically detect the number of input video sources, and determine the layout of the splicing window according to the number of video sources to implement the splicing processing of the input video sources, so that the layout of the splicing window does not need to be manually configured again when the number of video sources changes, the user operation is simplified, and the splicing output display effect can be improved.
