Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
Referring to fig. 1, a flowchart illustrating steps of an embodiment of a video data processing method according to an embodiment of the present invention is shown, and is applied to a video processing system, where the video processing system includes at least two IO processing modules and a GPU module, and each acquisition channel of the IO processing module is respectively used to receive video data with a specified resolution, and specifically may include the following steps:
step 101, acquiring to-be-processed video data by adopting an acquisition channel of the IO processing module, wherein the to-be-processed video data comprises video data with specified resolution and is split into the video data with the specified resolution;
in a specific implementation, the embodiments of the present invention may be applied to a video processing system that can support video data of 8K (7,680 × 4,320) and resolutions below 8K, where the resolution of 8K is 4 times (2 times each length and width) and 16 times (4 times each length and width) 1080P (1920 × 1080) of 4K (up to or near 4096 pixel values per line in the horizontal direction of an image, regardless of the aspect ratio).
The Input/Output (IO) processing module is a device capable of acquiring data Input and outputting data, and has at least one acquisition channel for acquiring data and at least one Output channel for outputting data. Specifically, the I/O card may support a high resolution, for example, an I/O card supporting 4K resolution video data, and may collect and output the 4K resolution video data.
A GPU (Graphics Processing Unit) module may be a microprocessor used for image and Graphics related arithmetic operations. In particular, the method can be a graphics card or other graphics processing device integrated with a GPU.
In a specific implementation, the video processing system may employ two 4K I/O cards. The I/O card is provided with two 4K video data acquisition channels, and can acquire video data with specified resolution or split the video data into video data with specified resolution through the acquisition channels, wherein the specified resolution is 4K resolution. Because the 8K resolution ratio is 4 times of the 4K resolution ratio, namely one path of video data with the 8K resolution ratio can be split into 4 paths of video data with the 4K resolution ratio, the two I/O cards can be adopted to collect the video data with the 8K resolution ratio. Specifically, the video data with 8K resolution is split into 4 paths of video data with 4K resolution, and then the 4 paths of video data with 4K resolution are respectively acquired by the acquisition channels of the two I/O cards, so as to realize the acquisition of the video data with 8K resolution. After the video data is collected, the video data can be processed by adopting the video card. The video processing system provides two interfaces, 12G-SDI and ST-2110 IP.
Wherein ST-2110 is a set of standards that standardize the carrying, synchronization and description of different IP entity streams in the on-site production process, for on-site production, playback and other professional media applications. The SDI interface is a digital component serial interface and is a digital video interface standard, and the 12G-SDI can transmit signals of 4K60fps at most.
102, acquiring video processing parameters aiming at the video data to be processed;
the video processing parameters comprise setting parameters during video data processing and graphic and text information added into the video, the setting parameters comprise color depth, a rendering mode, a mapping mode and the like, and the graphic and text information comprises pictures and characters.
Color depth in the field of computer graphics represents the number of bits used to store a 1-pixel color in a bitmap or video frame buffer, also known as bits per pixel (bpp). The color bit number is in binary bits (bit), and the number of colors is expressed by the number of bits, and the higher the color depth, the more colors are available. The color depth is illustrated by "n-bit color" (n-bit color). If the color depth is n bits, i.e. 2nThe color is selected and the number of bits used to store each pixel is n.
In the embodiment of the present invention, the setting of the rendering mode includes whether to start HDR (High-Dynamic Range, High Dynamic illumination rendering), and the setting of the mapping mode includes a mapping manner of an 8K segmented image, specifically, SQD or 2SI, where SQD is to divide an 8K image into 4 equal parts, and 2SI is to divide every two pixels of each row into 4 self images.
In a specific implementation, after the video data is collected by the I/O card, the video data may be transmitted to the GPU processing module for processing, and before the processing, system setting may be performed, including: whether 8-Bit or 10-Bit color depth is used, whether HDR is supported, and whether to go to 2SI mapping mode, etc.
103, processing the video data to be processed by adopting the GPU module according to the video processing parameters to obtain target video data;
after the video processing parameters are set, the GPU module processes the video data collected by the I/O card according to the set parameters, and the processing of the video data may include format conversion, color depth conversion, HDR turning on or off, adding custom images and/or text, setting video windowing display, switching mapping modes of the segmented images, and the like.
In a specific implementation, 2-channel 8K video data may be received, and then a custom image and/or text may be added to the video data, for example, when a program is rebroadcast, a picture or text may be added to a rebroadcast picture, or a subtitle may be added to a television program. The windowing process may be performed on the 2-way 8K video data, that is, the 2-way video data is combined into one screen, for example, data a and data B, and the windowing process may be performed on the data a and the data B, so that the data a is displayed in a reduced size on the left half of the display device, and the data B is displayed in a reduced size on the right half of the display device.
And step 104, outputting the target video data by adopting an output channel of the IO processing module.
After the GPU module processes the obtained target video data, the obtained target data is transmitted to the I/O card, and the I/O card outputs the target data.
In a specific implementation, the video processing system can output the processed target video data through the output channels of the two I/O cards.
In the embodiment of the invention, the acquisition channel of the IO processing module is adopted to acquire the video data to be processed, wherein the video data to be processed comprises the video data with the specified resolution and the video data split into the specified resolution, the video processing parameters aiming at the video data to be processed are acquired after the video data are acquired, and the GPU module is adopted to process the video data to be processed according to the video processing parameters to obtain the target video data and then output by adopting the output channel of the IO processing module. Windowing and image-text superposition of 2-path 8K or multi-path 4K video data can be realized.
In an exemplary embodiment, the step 101 of acquiring the to-be-processed video data by using the acquisition channel of the IO processing module includes:
when the video data to be processed is the video data with the non-specified resolution, dividing the video data to be processed into a plurality of sub-video data according to the specified resolution;
and respectively collecting the plurality of sub-video data by adopting the collection channel of the IO processing module.
In this example, the specified resolution is 4K and the unspecified resolution is 8K.
In a specific implementation, in order to implement the processing of 2-way 8K video data input, two I/O cards may be used to capture video data, where the I/O cards are 4K I/O cards, and each I/O card has 4 capture channels supporting 4K resolutions. Because 8K is 4 times of 4K, consequently can divide into 4 way 4K video data with 8K video data, then gather 1 way 8K video data wherein through 4 collection channels of two IO cards, other 4 collection channels gather another 1 way 8K video data to realize gathering 2 way 8K video data's purpose simultaneously.
The data collection method is described in detail below with reference to fig. 2, and fig. 2 is a schematic diagram illustrating a video data collection method according to an embodiment of the present invention. As shown in FIG. 2, there are I/O card 1 and I/O card 2, respectively, each having 4 acquisition channels, e.g., I/O card 1 having acquisition channels 11, 12, 13, and 14 and I/O card 2 having acquisition channels 21, 22, 23, and 24. After receiving the input 8K video data a and B, each path of 8K video data may be divided into 4 sub-video data, for example, the 8K video data a is divided into a1, a2, A3, and a4, the 8K video data B is divided into B1, B2, B3, and B4, and the two I/O cards respectively capture the video data through capture channels.
Specifically, the acquisition channels 11 and 13 of the I/O card 1 respectively acquire two paths of sub-video data a1 and a2 of the 8K video data a, and the acquisition channels 12 and 14 respectively acquire two paths of sub-video data B1 and B2 of the 8K video data B; similarly, the acquisition channels 21 and 23 of the I/O card 2 respectively acquire two paths of sub-video data A3 and a4 of the 8K video data a, and the acquisition channels 22 and 24 respectively acquire two paths of sub-video data B3 and B4 of the 8K video data B; therefore, 2 paths of 8K video data can be acquired through the two I/O cards.
In the embodiment of the invention, the video data with the non-specified resolution is divided into the sub-video data with the plurality of specified resolutions, and the acquisition channels of the I/O card are adopted to acquire the sub-video data, so that the simultaneous acquisition of 2 paths of 8K video data input and the simultaneous acquisition of multiple paths of 4K video data input can be realized, and the processing requirements of the multiple paths of high-definition video data input are met.
In an exemplary embodiment, the step 103 of processing, by using the GPU module, the to-be-processed video data according to the video processing parameter to obtain target video data includes:
and adding the image-text information into the sub-video data by adopting the GPU module, and synthesizing the sub-video data into target video data according to the set parameters.
In a specific implementation, after the GPU module receives the collected video data, the video data may be processed according to the setting parameters, such as adding graphics and text information to the video data, or performing windowing on 2-way input 8K video data.
In one example, the graphics information may be added to 2-way 8K video data, and synthesized into target video data, which is transmitted to the I/O card for output with a fill signal and a key signal. Wherein the fill signal is a signal for scanning an image block containing target and background pixels to thereby detect a fill pixel between target pixels located on the same row or column in the image block, and calculating a substitute pixel value based on pixel values of the target pixels in the image block, which is the content of the video data itself; the key signal maps the key information into a corresponding gray scale image by outputting a video signal, and the received gray scale image is converted into a corresponding Alpha value by the key mixing device, thereby completing the transmission of the transparent information. It can be seen that the key signals themselves are also video signals (with composite key signals, and also with numeric key signals) for describing the transparency of the image, which substantially reflects the Alpha value, one of the four parameters (R/G/B/Alpha, respectively) representing the 32-bit true color. It has wide application in many aspects such as subtitle superposition, superposition of image and background picture, etc.
In another example, the GPU processing module may perform windowing on 2-way 8K video data or multiple ways 4K video data, i.e. the video data is displayed in multiple windows. For example, performing 2-way windowing on 2-way 8K video data is to merge the 2-way 8K video data into one display window for display, specifically, the 2-way 8K video data may be divided equally and displayed on the left and right sides of the display window, or 1-way 8K video data therein is displayed in a full screen manner, and the other 1-way is displayed in a small window overlapping manner, which is the same principle for multi-way windowing of 4K video data, and the windowing manner may be set according to actual requirements, which is not limited in the embodiment of the present invention.
In the embodiment of the invention, the GPU module can add the graphic information into the video data to be processed or perform windowing processing on the video data to be processed according to the video processing parameters, so that windowing processing on 2-path 8K video data or multi-path 4K video data can be realized, and graphic packaging on the 2-path 8K video data can be realized.
In an exemplary embodiment, the step 104 of outputting the target video data by using the output channel of the IO processing module includes:
when the target video data is video data with non-specified resolution, dividing the target video data into a plurality of sub-target video data according to the specified resolution;
and respectively outputting the plurality of sub-target video data by adopting the output channel of the IO processing module.
In a specific implementation, after the GPU module finishes processing and obtains the target video data, the target video data may be transmitted to the IO processing module for output, and for the step and manner of the IO processing module outputting the target video data, the step and manner are the same as or similar to those of the IO processing module acquiring the input video data, but the transmission direction of the data is opposite, and details are not repeated here.

3. the I/O card transmits the acquired video data to a GPU module (in the example, a high-performance display card) for processing;
4. the high-performance display card processes the acquired video data according to the video setting parameters, including adding the graphic information into 2 paths of 8K video data, or windowing the 2 paths of 8K video data or multiple paths of 4K video data, and then synthesizing the video data into target video data;
