Description
Technical Field

Background
The MVR (Multi Video Review) function is to compress and splice input Video sources of a Video processor into a 1080p picture, and output the 1080p picture through an HDMI interface or a DVI interface. The user can receive 1080p pictures through the display and visually and real-timely monitor the state of the input video source in the video processor.
With the exponential rise of the application demand of large-screen display, people put forward more and more detailed requirements on video splicing products. For example, the resolution of the input video source is larger and larger, the number of the input video sources is more and more, and new layer processing requirements such as shadow, figure clipping, shading, special-shaped windows and the like are more and more varied. However, due to the fact that the size of an input video source is upgraded, resources meeting MVR functions occupy more and more, and the problem that the layer processing function with various types is limited at the same cost is accompanied, and the cost performance of a video processor is greatly affected. In the related art, the resource overhead of the MVR is often controlled by limiting the number of input video sources displayed in an MVR picture of a video processor, and a field worker selects the input video source to be displayed according to different scenes and displays the input video source on the MVR picture. In this way, when the number of input video sources is too large, the user needs to frequently switch the MVR picture to call the input video source to be previewed, and the operation workload is increased. In addition, when the usage scenario is complex, the user needs to reasonably arrange the access sequence of the input video sources, otherwise, all the input video sources in use may not be previewed in one page arrangement, which increases the difficulty in use.

[ first embodiment ] A method for manufacturing a semiconductor device
Referring to fig. 1, a multi-picture monitoring method is provided in a first embodiment of the present invention. As shown in fig. 1, the multi-screen monitoring method includes, for example, steps S11 to S13.
Step S11: receiving region information sent by a video processor;
step S12: performing zooming splicing processing on the target video source according to the region information to form a spliced picture;
step S13: and sending the spliced picture to the video processor, adding the spliced picture to a region to be compensated of a monitoring picture by the video processor to form a multi-picture monitoring picture, and outputting the multi-picture monitoring picture for display.
Specifically, the region information mentioned in step S11 includes, for example, information such as the screen layout of the region to be compensated and the screen resolution size of the region to be compensated. The video processor mentioned in step S11 is a video processor with MVR function, and typically includes programmable logic devices, a microcontroller, a memory, and other elements. The target video source mentioned in step S12 is, for example, a 1080P (resolution 1920 × 1080), a 4K1K (resolution 3840 × 1080) or a 4K2K (resolution 3840 × 2160) video source. The target video source format is, for example, HDMI (high Definition Multimedia interface), DVI (digital Visual interface), DP (display Port), SDI (serial digital interface), etc. It should be noted here that the target video source is at least one video source. The video source input interface corresponding to each video source is externally connected with video source equipment for example, so that the video source can be input through the video source input interface, or the video source input interface corresponding to a part of the video sources in the mentioned target video source is not externally connected with the video source equipment or is abnormally connected, so that the video sources are abnormally displayed, and the like. The forming of the spliced picture mentioned in step S12 forms, for example, a spliced picture. When the video source is abnormally displayed, information such as the abnormal display of the video source is displayed in a fixed area on the spliced screen. The monitor pictures mentioned in step S13 include, for example, input source pictures, PGM (Program, on-air picture) and PVW (preview, pre-monitor picture) of the video processor, and the input source pictures, the pre-monitor picture and the on-air picture are arranged in a row-column manner. The multi-picture monitoring picture is referred to as MVR picture, for example. Step S13 includes, for example, the video processor adding the stitched picture to the region to be compensated of the monitored picture at a ratio of 1:1, that is, after the video processor receives the stitched picture, the video processor directly adds the stitched picture to the region to be compensated at a ratio of 1:1 without scaling the stitched picture.
Further, before step S12, the multi-screen monitoring method of the present embodiment further includes, for example: and adjusting the image quality of the target video source. The image quality adjustment includes, for example: format conversion and parameter adjustment.
The format conversion is, for example, to convert the target video source into a uniform format target video source, and the uniform format target video source is, for example, an RGB format target video source. The mentioned parameter adjustment is for example in response to a human-computer interaction instruction, and some parameters such as brightness adjustment or chromaticity adjustment for the target video source are set to meet the user requirements. The mentioned human-computer interaction instructions are sent by a host computer, for example.
For better understanding of the present embodiment, a specific implementation of the multi-screen monitoring method according to the first embodiment of the present invention is described below with reference to fig. 2A and 2B.
The scenario set here is that the video processor accesses a plurality of paths of 4K extended video sources, for short, 4K input sources, through the source extender, and the video processor completes the MVR function, for example, the function of simultaneously monitoring all the input video sources without increasing more resources.
In the prior art, the source expander identifies the input video sources, performs image quality adjustment on all the input video sources, packages the input video sources and sends the input video sources to the video processor, and the hardware resources of the single functional source expander have a certain amount of surplus and cannot be well utilized.
As shown in fig. 2A and fig. 2B, the multi-picture monitoring method provided in the embodiment of the present invention utilizes the spare hardware resources of the source extender to pre-process all 4K input sources, i.e., the target video sources are scaled in advance according to the layout required by the MVR picture of the video processor to form a spliced picture and simultaneously transmitted to the video processor, and the video processor synthesizes the spliced picture with the already-prepared monitoring pictures according to the input source picture, PGM, and PVW of the video processor after receiving the spliced picture, and fills up the blank area, i.e., the area to be filled up, to form the final MVR picture. It should be noted that the shape of the blank area (i.e. the area to be compensated) in this embodiment is, for example, a shape in which a plurality of frames are arranged in a one-dimensional matrix as shown in fig. 2A, or a shape in which a plurality of frames are arranged in a two-dimensional matrix as shown in fig. 2B, but the invention is not limited thereto.
Since the scaling process of the target video source is already completed on the source expander, only the scaling ratio of 1:1, the consumed hardware resources can be almost omitted, and the realized MVR effect is completely consistent with the effect realized in the video processor and the picture quality.
In summary, the multi-screen monitoring method provided by this embodiment can avoid the tedious operation that the user needs to frequently switch the MVR screen to call the input video source to be monitored when the input video source is too many; the method and the device avoid the situation that when the use scene is complex, a user needs to reasonably arrange the input sequence of the input video sources, otherwise the input video sources in use cannot be monitored in one-page arrangement; the method and the device reduce the use difficulty, greatly reduce the resource overhead of realizing the same MVR function by the video processor after the video processor is accessed to the source expander, facilitate integration, do not limit the resolution and the quantity of input video sources, and reasonably utilize redundant hardware resources.
[ second embodiment ]
Referring to fig. 3, a second embodiment of the present invention provides a multi-screen monitoring apparatus. As shown in fig. 3, themulti-screen monitoring apparatus 20 includes, for example, aninformation receiving module 21, ascreen forming module 22, and ascreen transmitting module 23.
Theinformation receiving module 21 is configured to receive the region information sent by the video processor. Thepicture forming module 22 is configured to perform a scaling splicing process on the target video source according to the region information to form a spliced picture. Thepicture sending module 23 is configured to send the stitched picture to the video processor, so that the video processor adds the stitched picture to a region to be compensated of a monitored picture to form a multi-picture monitored picture and outputs the multi-picture monitored picture for display.
It should be noted that the multi-screen monitoring method implemented by themulti-screen monitoring device 20 of the present embodiment is as described in the first embodiment, and therefore, the detailed description thereof is omitted. Optionally, each module and the other operations or functions in the second embodiment are respectively for implementing the method in the first embodiment of the present invention, and are not described herein for brevity. The technical effect of themulti-screen monitoring apparatus 20 provided in this embodiment is the same as that of the multi-screen monitoring method in the first embodiment, and is not described herein again.
[ third embodiment ]
Referring to fig. 4, a third embodiment of the present invention provides a multi-picture monitoring method. As shown in fig. 4, the multi-screen monitoring method includes, for example, steps S31 to S35.
Step S31: receiving video source interface information sent by a source expander;
step S32: forming a monitoring picture with a region to be compensated according to the video source interface information;
step S33: sending the region information of the region to be complemented to the source expander, so that the source expander performs zooming splicing processing on a target video source according to the region information to form a spliced picture, and sending the spliced picture;
step S34: receiving the spliced picture, and adding the spliced picture to the region to be compensated of the monitoring picture to form a multi-picture monitoring picture;
step S35: and outputting the multi-picture monitoring picture for display.
Specifically, the source expander mentioned in step S31 is a video source expander, which has a single function and has spare hardware resources. The mentioned video source interface information includes, for example, each video source interface type and the number of video source interfaces. The monitoring screen mentioned in step S32 includes, for example, an input source screen, a pre-monitoring screen, and an on-air screen, and the input source screen, the pre-monitoring screen, and the on-air screen are arranged in rows and columns. The step S32 of forming the monitoring picture with the region to be compensated according to the video source interface information may be understood that the picture layout of the region to be compensated is related to the number of video source interfaces, which may be obtained by dividing the region to be compensated according to the number of video source interfaces, where the video sources corresponding to all the video source input interfaces of the source expander are the target video sources. The method can also be understood as that visual frequency source input interfaces are determined according to the video source interface information, the area to be compensated is divided according to the number of the selected target video source input interfaces to obtain the picture layout, and the video source corresponding to the selected target video source input interface is the target video source. The region information mentioned in step S33 includes, for example, information such as the picture layout of the region to be compensated and the picture resolution size of the region to be compensated. The target video source mentioned in step S33 is, for example, a 1080P (resolution 1920 × 1080), a 4K1K (resolution 3840 × 1080) or a 4K2K (resolution 3840 × 2160) video source. The target video source format is, for example, HDMI (high Definition Multimedia interface), DVI (digital Visual interface), DP (display Port), SDI (serial digital interface), etc. It should be noted here that, for example, video source devices are externally connected to video source input interfaces corresponding to the respective target video sources, so that video sources are input through the video source input interfaces; or the video source input interfaces corresponding to some video sources in the mentioned target video source are not connected with external video source equipment or are connected abnormally, so that the video sources are displayed abnormally, and the like. The forming of the spliced picture mentioned in step S33 forms, for example, a spliced picture. The multi-picture monitoring picture referred to in step S34 is, for example, an MVR picture. Step S34 includes, for example, adding the stitched picture to the to-be-compensated region of the monitored picture at a 1:1 ratio. Namely, after the video processor receives the spliced picture, the spliced picture is directly added to the region to be compensated according to the proportion of 1:1 without scaling.
It should be noted that the difference between the multi-screen monitoring method disclosed in the present embodiment and the multi-screen monitoring method disclosed in the first embodiment of the present invention is that the present embodiment is described from the perspective of a video processor, for example, and the multi-screen monitoring method disclosed in the first embodiment is described from the perspective of a source expander, for example, the multi-screen monitoring methods implemented by the two methods are the same, and the descriptions of the specific related steps can be referred to each other.
In summary, the multi-screen monitoring method provided by this embodiment can avoid the tedious operation that the user needs to frequently switch the MVR screen to call the input video source to be monitored when the input video source is too many; the method and the device avoid the situation that when the use scene is complex, a user needs to reasonably arrange the input sequence of the input video sources, otherwise the input video sources in use cannot be monitored in one-page arrangement; the method and the device reduce the use difficulty, greatly reduce the resource overhead of realizing the same MVR function by the video processor after the video processor is accessed to the source expander, facilitate integration, do not limit the resolution and the quantity of input video sources, and reasonably utilize redundant hardware resources.
