Description
Technical Field
The invention relates to the technical field of display, in particular to a layer display method and a layer display device.
Background
In video processing devices such as video switchers and video splicers, it may support both single layer processing and multi-layer processing. When the layers opened by one input source are all output and displayed on one display interface, the video processing equipment only needs to consume one scaling processing channel. When a layer opened by one input source is spliced through a plurality of display interfaces to display a whole image, that is, when one layer spans a plurality of display interfaces, a corresponding number of scaling processing channels need to be consumed, for example, when the layer opened by one input source is displayed on two display interfaces, two image scaling processing channels need to be consumed. Each image scaling processing channel is typically configured with a preceding scaling unit and a succeeding scaling unit. At this time, the layer data of the input source acquired by the preceding stage scaling units of the two scaling processing channels are the same, and the configuration of the preceding stage scaling unit is also the same, so that the processing results of the two preceding stage scaling processing channels are ensured to be consistent. However, the configurations of the post-stage scaling units of the two scaling processing channels are different, and each post-stage scaling unit only reads the area data to be scaled and displayed from the volatile memory (also called memory), and outputs and displays the area data through the two display interfaces after scaling processing. At this time, the processing capacity of one preceding stage scaling unit in the two scaling processing channels is wasted, which reduces the layer processing capacity of the video processing apparatus. Further, the video processing device also supports multi-layer processing, i.e. it may configure multiple scaling processing channels to process layer data of multiple input layers. When a plurality of layers opened by a plurality of input sources, for example, three input sources, need to be displayed or roamed in a plurality of display interfaces, the number of internal scaling processing channels that need to be consumed is uncertain. Therefore, the layer scaling processing method not only limits the number of layers supported by the layer scaling processing method, but also causes trouble to users, so that the users cannot clearly know the number of layers supported by the device.

[ first embodiment ] A method for manufacturing a semiconductor device
As shown in fig. 1, a first embodiment of the present invention provides a layer display method. The layer display method can be applied to video processing equipment, and can be executed by a programmable logic device of the video processing equipment. Specifically, the layer display method provided in the embodiment of the present invention includes, for example, the steps of:
s11: acquiring first layer data;
s13: performing first scaling processing on the first layer data through a first preceding stage scaling unit of a first scaling processing channel to obtain first processed layer data, and temporarily storing the first processed layer data;
s15: respectively reading the first processed layer data to obtain a plurality of first region data and transmitting the plurality of first region data to a plurality of first post-stage scaling units of the first scaling processing channel;

s19: and outputting the processed first area data in a one-to-one correspondence manner through a plurality of first display interfaces.
Thus, in the embodiment of the present invention, the first pre-stage scaling unit in the first scaling channel scales and temporarily stores the input layer data, then respectively reading the regional image data of the corresponding region to be displayed, transmitting the regional image data to a plurality of first post-stage scaling units which are in one-to-one correspondence with a plurality of display interfaces of the first layer data to be displayed in the same first scaling processing channel to respectively perform second scaling processing, finally outputting and displaying through the plurality of display interfaces in one-to-one correspondence, the display of the input image layers across a plurality of display interfaces can be realized through the same zooming processing channel, compared with the prior art, the method saves the resources of the zooming processing channel when the input layer is displayed across a plurality of display interfaces, the programmable logic device can process more input layer data, and therefore the processing capacity of the video input layer is improved.
Furthermore, the number of the first pre-stage scaling units in one scaling processing channel is one, so that the scaling processing channel resources can be saved.
Wherein, step S13 specifically includes:
performing reduction processing or equal-scale scaling on the first layer data through one first-stage scaling unit to obtain first processed layer data, and temporarily storing the first processed layer data to a volatile memory;
wherein, step S17 specifically includes:
and performing amplification processing or equal-proportion scaling processing on the plurality of first area data in a one-to-one correspondence manner through the plurality of first post-stage scaling units to obtain a plurality of processed first area data.
Therefore, the capacity of the volatile memory can be saved, more data can be stored, and the hardware cost can be saved by carrying out the reduction or equal-proportion scaling processing by the front-stage scaling unit and carrying out the amplification or equal-proportion scaling processing by the rear-stage scaling unit.
The first area data is part or all of the first processed layer data. Specifically, when at least two first region data of the plurality of first region data are the same, at least two processed first region data corresponding to the at least two first region data are also the same, and thus, the image copying function can be realized. Therefore, the layer data can be copied and displayed.
When two first area data in the plurality of first area data are the same; the first post-scaling units, which respectively read a plurality of first region data from the first processed layer data and transmit the first region data to the first scaling processing channel, specifically include: respectively reading the layer data after the first processing to obtain two first area data; and inputting the two first region data to two rear-stage scaling units in the plurality of first rear-stage scaling units in reverse data input order. Therefore, mirror image display of the layer data can be realized.
In addition, as shown in fig. 2, before outputting the plurality of processed first region data through the plurality of first display interfaces in a one-to-one correspondence manner, the layer display method may further include, for example:
s41: acquiring second layer data;
s43: performing third scaling processing on the second layer data through a second preceding stage scaling unit of a second scaling processing channel to obtain second processed layer data and temporarily storing the second processed layer data;
s45: respectively reading the second processed layer data to obtain a plurality of second region data and transmitting the second region data to a plurality of second post-stage scaling units of the second scaling processing channel;
s47: performing fourth zooming processing on the plurality of second region data in a one-to-one correspondence manner through the plurality of second post-stage zooming units to obtain a plurality of processed second region data; and
s49: and superposing the plurality of processed second region data to the plurality of processed first region data in a one-to-one correspondence manner to obtain a plurality of superposed data.
At this time, the outputting the plurality of processed first region data in a one-to-one correspondence through the plurality of first display interfaces specifically includes: and outputting the plurality of superposed data in a one-to-one correspondence manner through the plurality of first display interfaces.
Therefore, multi-interface display of multiple layers can be achieved through different scaling processing channels, such as the first scaling processing channel and the second scaling processing channel, system resources are saved, and layer processing capacity of the device is improved.
In order to facilitate understanding of the present invention, each step of the layer display method of the present embodiment will be described in detail below.
The layer display method provided by the embodiment of the invention can be suitable for realizing layer multi-interface display on video processing equipment. Typically, the video processing device may include, for example, a video splicer, a video switcher, and the like having a layer multi-interface display function such as a layer scaling process, and the like. Specifically, as shown in fig. 3, the video processing device 100 includes, for example, a microcontroller 110, a programmable logic device 120, a volatile memory 130, and a plurality of display interfaces 141, 142, 143, for example. The microcontroller 110 is connected to the programmable logic device 120, and the programmable logic device 120 is connected to the volatile memory 130. The programmable logic device 120 is also connected to a plurality of display interfaces 141, 142, and 143, respectively. More specifically, the Programmable logic device 120 is, for example, an FPGA (Field Programmable Gate Array), and is configured to receive the layer data, perform processing such as scaling processing, superimposing processing, and the like on the layer data, and output the processed image data to a display screen through the display interfaces 141, 142, and 143 for display. The programmable logic device 120 is configured with a scaling channel and a layer overlay module, so as to implement scaling processing, overlay processing, and the like of layer data. The microcontroller 110 may be, for example, an MCU, which is mainly used for loading FPGA programs, transceiving control instructions, and communicating with other devices such as an upper computer, etc. The volatile memory 130 may be, for example, a DDR (Double Data Rate SDRAM), which is mainly used for buffering Data and information during the operation of the video processing device, especially the programmable logic device 120. The layer display method provided by the embodiment of the invention mainly includes that the programmable logic device 120 performs scaling processing on input layer data through a first pre-stage scaling unit in a first scaling processing channel and temporarily stores the layer data, then reads area image data of an area to be displayed respectively through a plurality of first post-stage scaling units in the same scaling processing channel and performs second scaling processing respectively, and finally outputs and displays the area image data through a display interface corresponding to one.
First, as shown in fig. 4, the programmable logic device 120 obtains first layer data of a first input layer received by the video processing apparatus 100.
The programmable logic device 120 performs a first scaling process on the first layer data through a first pre-stage scaling unit of a first scaling process channel to obtain first processed layer data, and temporarily stores the first processed layer data. Specifically, the programmable logic device 120 performs a first scaling process on the first layer data to obtain first processed layer data, and then temporarily stores the first processed layer data to the nonvolatile memory 130 connected to the programmable logic device 120. The first scaling process is, for example, a reduction process or an equal scaling process (i.e., a scaling ratio is 1:1), so that the space occupation of the volatile memory 130 by the first layer data can be reduced, and resources can be saved. The first scaling method herein can be implemented by using the existing scaling method, and the details of the present invention are not repeated herein.
Then, the programmable logic device 120 reads the first processed layer data to obtain a plurality of first region data, and transmits the plurality of first region data to a plurality of first post-stage scaling units of the first scaling channel. The plurality of first subsequent scaling units here are, for example, first subsequent scaling units configured for a plurality of display interfaces, for example, the display interface 1 and the display interface 2 in fig. 4, and the number of the plurality of first subsequent scaling units is equal to and corresponds to the number of the display interfaces one to one. In addition, the plurality of first area data here may be, for example, layer data in the first layer data to be displayed by each display interface. For example, the first layer data includes layer data of an upper area and a lower area, where one display interface is used to output layer data of an upper area for display, and the other display interface is used to output layer data of a lower area for display, and after images output and displayed by the two display interfaces are spliced, the whole image picture of the first layer data is obtained. That is, the data in the plurality of first region data may be layer data of different regions or portions in the first layer data. Of course, each of the first area data of the plurality of first area data may also be the same area or part of the layer data, so that all the display interfaces output and display the same picture, that is, the picture may be determined according to the position where the display screen connected to the display interface 1 or 2 needs to display the image data of the first layer data. When at least two first area data in the plurality of first area data are the same, at least two processed first area data corresponding to the at least two first area data are also the same, and thus, the image copying function can be realized. When two first area data in the plurality of first area data are the same; the programmable logic device respectively reads the layer data after the first processing to obtain two same first area data; and inputting the same two first region data to two subsequent scaling units of the plurality of first subsequent scaling units in reverse data input order, respectively. Therefore, mirror image display of the layer data can be realized. Thus, the layer processing capability of the video processing device 100 is improved and the display effect of the product is improved without occupying more scaling processing channel resources.
Then, the programmable logic device 120 performs a second scaling process on the plurality of first region data in a one-to-one correspondence manner through a plurality of first post-stage scaling units to obtain a plurality of processed first region data. The second scaling process here may be, for example, equal scaling (scaling of 1:1) or an enlargement process. It should be noted here that each first subsequent scaling unit is configured with a buffer area, that is, the number of the buffer areas is consistent with the number of the first subsequent scaling units, and the buffer areas are in one-to-one correspondence to buffer the processed first region data. For example, as shown in fig. 6, each first subsequent stage scaling unit is configured with a buffer a behind it, and the two buffer a are respectively used for buffering two processed first region data to be output through the display interface 1 and the display interface 2.
Finally, the programmable logic device 120 outputs the processed first region data through the plurality of first display interfaces in a one-to-one correspondence manner. As shown in fig. 6, the display interface 1 and the display interface 2 are respectively connected to the display screens and spliced into a first display screen to display the picture of the first layer data.
Therefore, in the embodiment of the invention, the first pre-stage scaling unit in the first scaling channel scales the input layer data and stores the scaled layer data temporarily, then, respectively reading the regional image data of the corresponding region to be displayed and respectively carrying out second zooming processing through a plurality of first post-stage zooming units which are in one-to-one correspondence with a plurality of display interfaces of the first layer data to be displayed in the same first zooming processing channel, finally, outputting and displaying through the plurality of display interfaces in one-to-one correspondence, this may enable display of input layers across multiple display interfaces via one scaling processing channel, compared with the prior art, the method saves the resources of the zooming processing channel when the input layer is displayed across a plurality of display interfaces, the programmable logic device can process more input layer data, and therefore the processing capacity of the video input layer is improved.
In addition, when the video processing apparatus 100 needs to process the input multiple layer data, multiple scaling channels need to be configured in the programmable logic device 120 to implement respective scaling and overlaying processes on the input multiple layer data. For example, as shown in fig. 5, the first layer data is processed through a first scaling channel of the programmable logic device 120; the second layer data is processed through a second scaling channel of the programmable logic device 120. Specifically, as shown in fig. 5, before the programmable logic device 120 outputs the processed first region data through the plurality of first display interfaces in a one-to-one correspondence manner, the programmable logic device 120 obtains the second layer data and processes the second layer data through the second scaling channel. The programmable logic device 120 performs third scaling on the second layer data through a second pre-stage scaling unit of a second scaling channel to obtain second processed layer data, and temporarily stores the second processed layer data. The third scaling processing here may also be, for example, reduction processing or equal-scale (processing ratio is 1:1) processing. The third scaling process may be a process different from the first scaling process or the same as the first scaling process, and the present invention is not limited thereto. In addition, the programmable logic device 120 temporarily stores the second processed layer data into a volatile memory, where the volatile memory may be the same as the volatile memory described above, or may be a different volatile memory, and the disclosure is not limited thereto. The programmable logic device 120 then performs a fourth scaling process on the plurality of second region data through the plurality of second post-scaling units in a one-to-one correspondence manner to obtain a plurality of processed second region data. Then, the programmable logic device 120 performs a second scaling process on the plurality of second region data in a one-to-one correspondence manner through the plurality of second post-stage scaling units to obtain a plurality of processed second region data; and then the programmable logic device 120 superimposes the plurality of processed second area data to the plurality of processed first area data in a one-to-one correspondence manner through a plurality of layer superimposing modules, so as to obtain a plurality of superimposed data. Finally, the programmable logic device 120 outputs the plurality of superimposed data after the superimposition processing through the plurality of first display interfaces in a one-to-one correspondence manner. The embodiment of the invention only uses two input layer data to carry out the layer display method, for example, the processing method is similar when a plurality of input layer data need to be displayed across the display interface, so that the layer data processing capability of the equipment is improved, more layer data can be processed, and more display effects are realized. In addition, it is worth mentioning here that the layer overlay processing module may be implemented by using an overlay processing technology mature in the prior art.
In summary, in the embodiment of the invention, the first pre-stage scaling unit in the first scaling channel scales the input layer data and temporarily stores the scaled layer data, then, respectively reading the regional image data of the corresponding region to be displayed and respectively carrying out second zooming processing through a plurality of first post-stage zooming units which are in one-to-one correspondence with a plurality of display interfaces of the first layer data to be displayed in the same first zooming processing channel, finally, outputting and displaying through the plurality of display interfaces in one-to-one correspondence, the display of the input image layers across a plurality of display interfaces can be realized through the same zooming processing channel, compared with the prior art, the method saves the resources of the zooming processing channel when the input layer is displayed across a plurality of display interfaces, the programmable logic device can process more input layer data, and therefore the processing capacity of the video input layer is improved. In addition, the copying and/or mirror image display of the image layer can be realized through more post-stage scaling units in the same scaling processing channel, and the system resources are further saved. Moreover, multi-layer cross multi-interface display is realized through different scaling processing channels, system resources are saved, and the layer processing capacity of the device is improved.
