Description

Technical Field

[0001] This invention relates to the field of digital video signal encoding, and in particular to a video transmission method, a video reception method, and related apparatus. Background Technology

[0002] Lossless video signal transmission refers to the transmission of video signals without any loss of the original data, thus ensuring video quality. Lossless video signal transmission can guarantee video clarity, color accuracy, and smoothness, thereby improving the viewing experience.

[0003] Most lossless video signal transmission technologies work by losslessly compressing the original image signal, transmitting it over a network to the receiving end, and then decoding and restoring it for output. Related technologies include deep compression schemes such as H.264 and H.265. However, current codec chips convert the image to YUV420 before encoding, which results in the loss of many color components, making the encoded image unable to meet the requirements of visually lossless quality.

[0033] In the following description, specific details such as particular system architectures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of this application. However, those skilled in the art will understand that the embodiments of this application may also be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, electronic devices, and methods are omitted so as not to obscure the description of the embodiments of this application with unnecessary detail.

[0034] It should be noted that although a logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in a different order than that shown in the flowchart. The terms "first," "second," etc., in the specification, claims, and the aforementioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0035] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] YUV format: YUV is a color encoding method that uses luminance (Y) and chrominance (U, V) to specify pixel color. In this encoding method, each pixel contains Y, U, and V components, but the Y and UV components can be discrete. A complete image can be displayed even without U and V components, although it will be black and white. Furthermore, there are various types of YUV formats. For example, each Y component may have its own corresponding U and V components, such as the YUV444 format; or several Y components may share U and V components, such as the YUV422 format.

[0037] Video encoding is a file compression technique that reduces the size of video and image files through compression. Original image and video files often contain redundant information, such as the correlation between adjacent pixels in an image and the correlation between adjacent frames in a video. Human vision is not sensitive to some of this redundant information. The process of compressing this redundant information is video encoding.

[0038] Deep compression is a video coding technique where the encoder searches for similar regions in consecutive images, identifying similar areas and their positional offsets. It then encodes the differences between these similar regions and their motion vectors. Differences between different similar regions are shared or quantized stepwise according to a bitrate control strategy. Based on search algorithms and coding strategies, deep compression includes H.264, H.265, JPEG, and AVS, among others.

[0039] A macroblock is a segmented unit in video coding that employs different compression strategies. Each frame of a video is divided into multiple macroblocks.

[0040] H.264 encoding is a coding standard known for its high compression, high quality, and support for streaming media transmission across various networks. It is a lossy encoding method. H.264 defines three types of frames: I-frames, P-frames, and B-frames. A fully encoded frame is called an I-frame. A P-frame is a frame that references a previous I-frame and only includes the differences in its encoded portion. A B-frame is a frame that references both preceding and following frames. The core algorithms of H.264 are intra-frame compression and inter-frame compression. The core of the H.264 algorithm is comparing the differences between I-frames, P-frames, and B-frames. When the differences are small, H.264 can provide a better compression ratio and faster encoding speed.

[0041] Figure 1 This is a schematic diagram of a video transmission system according to an embodiment of this application. (Reference) Figure 1The video transmission system 10 of this application includes a transmitter 11 and a receiver 12, which are connected via a network. The transmitter 11 includes a first logic chip, a first digital signal processor, and a first main processor. Figure 1 (Not shown in the image), the receiver 12 includes a second digital processor, a second main processor, and a second logic chip. Figure 1 (Not shown in the image); The first main processor is connected to the first logic chip and the first digital signal processor, respectively. The second main processor is connected to the second logic chip and the second digital signal processor, respectively. The first and second main processors are communicatively connected to achieve the communication connection between the transmitter 11 and the receiver 12. The first and second logic chips can be, for example, image signal processors (ISPs) with image conversion functions, field-programmable gate arrays (FPGAs), general-purpose central processing units (CPUs), or other programmable computing devices. The first and second digital signal processors are digital signal processors (DSPs). Similarly, a custom FPGA can also be used to implement the functions of a digital signal processor, but considering I / O bandwidth and cost, a digital signal processor is a more preferred embodiment. The first and second main processors are not limited; any non-dedicated computing device with good computing power can be used, such as a general-purpose central processing unit (CPU). The communication connection between the first main processor and the second main processor can be implemented through the built-in devices of the transmitting end 11 and the receiving end 12, such as network cards, or through other peripheral devices, such as mobile networks, or through direct network connection. The connection method is not limited here. The first logic chip, first digital signal processor, first main processor, second digital processor, second main processor, and second logic chip in the above video transmission system can all be implemented using existing devices. This eliminates the need to design separate digital signal processors and logic chips to implement the video transmission and video reception methods of the embodiments of this application, thereby reducing design costs.

[0043] The video sending method according to the embodiments of this application will be described in detail below.

[0044] Figure 3 This is a flowchart of a video transmission method according to an embodiment of this application, see reference. Figure 3 This method is applied to, for example Figure 1 The transmitter 11 in the middle includes:

[0045] S110: Obtain the original transmitted video and obtain the original transmitted image based on the original transmitted video;

[0046] S120: Convert the original transmitted image into a preset image format to obtain the converted transmitted image;

[0047] S130: The converted and transmitted image is split according to color information to obtain multiple color images, including: a first color image, a second color image and a third color image;

[0048] S140: Encode multiple color images according to a preset encoding method to obtain a first encoded image of the first color image, a second encoded image of the second color image, and a third encoded image of the third color image;

[0049] S150: Convert the first coded image, the second coded image, and the third coded image into transmission information;

[0050] S160: Send the transmission information to the receiving end so that the receiving end can obtain the original transmitted image based on the transmission information and obtain the original transmitted video based on the original transmitted image.

[0051] According to this video transmission method, by splitting each original transmitted image in the original transmitted video into different first color images, second color images, and third color images at the sending end, and encoding and compressing them through a preset encoding method, the network pressure is reduced, and the receiving end can decode the received transmission information to obtain the original transmitted video that meets the requirements of visual lossless image quality.

[0052] Specifically, in S110, the original transmitted video is split. Since the original transmitted video is composed of multiple frames of images ordered chronologically, it can be easily split into multiple original transmitted images. In some embodiments, S110 is performed on a dedicated first logic chip, which is less expensive than general-purpose computing chips and, due to its specialization, allows for faster splitting.

[0053] In some embodiments, when splitting the original transmitted video into multiple original transmitted images, the position information of each original transmitted image within the original transmitted video is recorded. This position information is then converted into time frames for use in subsequent steps. However, in other embodiments, due to a better decoding and sorting method, time frames may not be obtained.

[0054] In S120, which converts the original transmitted image into a preset image format to obtain a converted transmitted image, specifically, the original transmitted image is converted into YUV444 format. YUV444 format is a type of YUV format where one pixel includes three components: Y, U, and V, and each pixel occupies 3 bytes. Similarly, S120 can be performed on a dedicated first logic chip, but another logic chip can also be used to handle the format conversion, thereby improving conversion efficiency. In some embodiments, the converted transmitted image can also be an image in the RGB color model (hereinafter referred to as RGB image).

[0055] In S130: The converted and transmitted image is split according to color information to obtain multiple color images, including a first color image, a second color image, and a third color image. Specifically, the first color image, the second color image, and the third color image are obtained from the YUV444 image split in S120, or the converted and transmitted image is an RGB image, obtained by splitting the RGB image into its three components. In embodiments where the converted output image is in YUV444 format, the color information refers to the information corresponding to the three components of YUV, such as luminance information, chrominance information, and saturation information. Therefore, S130 includes:

[0056] S131: Extract the first color component of the transmitted image based on the brightness information, and convert the first color component into a first color image;

[0057] S132: Extract the second color component of the transmitted image based on the chromaticity information, and convert the second color component into a second color image;

[0058] S133: Extract the third color component of the transmitted image based on the concentration information, and convert the third color component into a third color image.

[0059] In this design, the first color component can refer to luminance information (Y), the second color component can refer to chromaticity information (U), and the third color component can refer to density information (V). The first color image is a YUV400 format image containing all information of the first color component, the second color image is a YUV400 format image containing all information of the second color component, and the third color image is a YUV400 format image containing all information of the third color component. That is, the original YUV444 format converted output image is split into three YUV400 grayscale images. It is important to note that in this embodiment, the second and third color images differ from typical YUV400 images. For example, the first color image is actually a grayscale image of the original converted output image, while the second and third color images, although grayscale in form, are actually information carriers of the U and V components of the YUV444 image. During this process, no information in the converted output image is lost.

[0060] In addition, in some other embodiments, the first color image, the second color image, and the third color image may also be the yellow, green, and blue components in an RGB image, which are converted from an RGB image to YUV444 and then split into a first color image, a second color image, and a third color image of YUV400 through format change.

[0061] The above step S130 can be completed by the first logic chip, but another logic chip can also be used to handle the format conversion. The first logic chip includes multiple decoders, so the above YUV444 splitting can be performed synchronously or in parallel.

[0062] In S140: Multiple color images are encoded according to preset encoding methods to obtain a first encoded image of the first color image, a second encoded image of the second color image, and a third encoded image of the third color image. The first color image is encoded, for example using existing encoding formats such as H.264, H.265, JPEG, or AVS; no specific limitation is made here. However, it is important to note that when encoding, a standard must be selected that ensures the resulting image and video after subsequent decoding and splicing still conform to a lossless standard visible to the naked eye.

[0063] The above encoding can be performed in a first digital signal processor (DSP), which may include multiple encoders, thereby simultaneously encoding the first color image into a first coded image, the second color image into a second coded image, and the third color image into a third coded image. This achieves high encoding efficiency.

[0064] In some embodiments, since a time frame is obtained in S110, and considering subsequent sorting, the corresponding time frame can be added to the first coded image, the second coded image, and the third coded image during encoding. The time frame represents the position of the original transmitted image corresponding to the first coded image, the second coded image, and the third coded image within the original transmitted video. The encoding method for adding the time frame can be by adding a storage bit to each of the first coded image, the second coded image, and the third coded image during encoding to represent the time frame information.

[0065] In other embodiments, during S150: converting the first coded image, the second coded image, and the third coded image into transmission information, the time frame of the original transmission image corresponding to the first coded image, the second coded image, and the third coded image is obtained. When converting the first coded image, the second coded image, and the third coded image into transmission information, the time frame information is encoded into the transmission information and transmitted as part of the transmission information. The method of converting the transmission information is not limited, as long as existing packetization methods and transmission protocols do not lose the information contained in the first coded image, the second coded image, and the third coded image, are acceptable. Alternatively, partial information loss may be allowed, but the total loss should ensure that the original transmission video obtained by the receiving end after receiving and decoding the transmission information still meets the standard of visual losslessness.

[0066] Finally, the transmission information obtained in S150 is sent to the receiving end in S160, so that the receiving end can obtain the original transmitted image based on the transmission information and obtain the original transmitted video based on the original transmitted image, and send it to the receiving end.

[0067] Through the above embodiments, after converting the original transmitted video into a YUV444 format image, three color components in the YUV444 are extracted to obtain three YUV400 format images, and the YUV400 format images are encoded and transmitted respectively. No loss or information loss occurs during the assembly and transmission process.

[0068] In related technologies, there is a technique that splits a YUV444 image into two YUV420 images. In this technique, the UV components of the two YUV420 images only represent half of the V component of the original image. This results in the loss of spatial reference feature correlation between the Y, U, and V components. Therefore, during encoding, the search algorithm cannot calculate reasonable macroblock motion data, and the algorithm struggles to obtain similarity points between I-frames, P-frames, and B-frames, increasing the bandwidth required for encoding. For example, in the technique of splitting a YUV444 image into two YUV420 images, a complete U component is split and encoded independently by two encoders. This prevents the encoder from referencing the U component information in the other encoder. Assuming the two encoders are encoder A and encoder B, a portion of the U component information in the Nth frame (defined as an I-frame by the encoder) belonging to encoder A may be in the U component information of encoder B in the N+1th frame (defined as a P-frame by the encoder). In this case, the search algorithm cannot obtain the correlation between the U component information of the Nth and N+1th frames, resulting in the use of a lower compression ratio encoding strategy and increasing the overhead of the first digital signal processor. Furthermore, because some feature information is lost during the splitting process, the image will also lose some sharpness. In other words, splitting it into two YUV420 images cannot achieve a lossless effect to the naked eye.

[0069] Figure 4 This is a schematic diagram illustrating the encoding of an embodiment of this application. For example... Figure 4 As shown, the first digital signal processor includes a first encoder, a second encoder, and a third encoder. The first digital signal processor can simultaneously encode the first color image, the second color image, and the third color image of the Nth time frame to obtain the corresponding first encoded image, second encoded image, and third encoded image. During the encoding process, the first color image of the N+1th time frame is processed using the same first encoder as the first color image of the Nth time frame. This means the first encoder can obtain all the information of the color components contained in the first color image. Therefore, when a macroblock in the first color image of the N+1th time frame moves compared to the first color image of the Nth time frame, the encoder can better calculate the motion vector through the search algorithm and perform effective compression, resulting in less information loss during color image encoding. Similarly, a similar effect occurs for the second and third color images.

[0070] Therefore, the embodiments of this application can reduce encoder overhead and achieve better compression results.

[0071] The following describes the video receiving method corresponding to the video sending method described above.

[0072] refer to Figure 5 , Figure 5This is a video transmission method for receiving and processing transmission information sent by the video transmission method of this application, comprising:

[0073] S210: Receive transmission information and extract multiple encoded images from the transmission information. The encoded images include: a first encoded image, a second encoded image, and a third encoded image.

[0074] S220: Decode each encoded image according to a preset decoding method to obtain a color image, which includes: the first color image of the first encoded image, the second color image of the second encoded image, and the third color image of the third encoded image;

[0075] S230: Store multiple color images into a buffer, and perform image alignment on the color images in the buffer to obtain at least one image sequence;

[0076] S240: The original transmitted image is obtained by synthesizing the image sequence. The image sequence includes: the first color image, the second color image, and the third color image of the original transmitted image.

[0077] S250: Receives multiple raw transmitted images to generate raw transmitted video.

[0078] Specifically, in S210: receiving transmission information and extracting multiple coded images from the transmission information, the coded images include a first coded image, a second coded image, and a third coded image, with the decoding method corresponding to the encoding method and protocol used by the sending end when generating the transmission information. Thus, the first coded image, the second coded image, and the third coded image are obtained.

[0079] In some embodiments, the time frame of the original transmitted image corresponding to the first coded image, the second coded image and the third coded image in the original transmitted video can also be obtained through transmission information. The time frame represents the position information of the original transmitted image corresponding to the color image obtained after the coded image is decoded according to a preset decoding method in the original transmitted video.

[0080] In S220: Each encoded image is decoded according to a preset decoding method to obtain a color image. The color image includes: the first color image of the first encoded image, the second color image of the second encoded image, and the third color image of the third encoded image. The preset decoding method corresponds to the preset encoding method used in the video transmission method described above to encode the first color image, the second color image, and the third color image to obtain the first encoded image, the second encoded image, and the third encoded image. For example, it can be an existing compression method such as H.264, H.265, or JPEG. Preferably, H.264 or H.265 format is used for encoding.

[0081] In some embodiments, the decoded first color image, second color image, and third color image are the same as in the video transmission method described above, representing the Y, U, and V components of a YUV444 image, respectively. The first color image, second color image, and third color image are all YUV400 format images. Similar to the transmission method, the first color image, second color image, and third color image can also be images representing the RGB color components.

[0082] In S230, where multiple color images are stored in a buffer and aligned within the buffer to obtain at least one image sequence, S220 and S230 can be executed by a second digital signal processor. The second digital signal processor includes three channels: the first color image is processed by the first channel, the second color image by the second channel, and the third color image by the third channel. In some embodiments, no time frame is obtained in S210, therefore the color images need to be sorted to control the speed at which each color image enters and exits the second digital signal processor. This ensures that all color images belonging to the same original transmitted image are input to the second digital signal processor and aligned to obtain an image sequence before a color image belonging to another original transmitted image is input to the second digital signal processor. This is because the time it takes to obtain the first, second, and third color images from the first, second, and third coded images is uncertain; there may be a situation where a color image belonging to the previous frame has not yet been output when a color image belonging to the next frame has already been output. If the input is not controlled, the image sequence will become disordered, and the image sequence may contain color images belonging to different original transmitted images.

[0083] The image sequence in this application refers to an image group consisting of a first color image, a second color image, and a third color image belonging to the same original transmitted image. In S230, the three color images need to be integrated into an image sequence and then output together from the second digital signal processor. This is because when the second digital signal processor generates color images, factors such as internal scheduling and buffering may cause the output signals to REPEAT (repeat the previous frame) or LOST (discard a frame), or the start times of the output signals may differ, resulting in significant deviations in the start times of the three channels of the second digital signal processor. Due to the continuous nature of video signal decoding, when the above problems occur, the images from the three channels of the second digital signal processor will not be output synchronously for a considerable period of time. Therefore, a buffer needs to be designed to ensure that the three color images belonging to the same original transmitted image can be output only after alignment to obtain an image sequence.

[0084] In other embodiments, a time frame is obtained in step S210 to resolve the potential chaos in the image sequence described above. The second digital signal processor used to execute S230 sets up a first buffer and a second buffer, aligning the color images by alternately writing them to different buffers based on time frames. Therefore, in some embodiments, before executing S230, the following needs to be performed:

[0085] S231: Decode a time frame from the encoded image. The time frame represents the position information of the original transmitted image corresponding to the color image obtained after the encoded image is decoded according to the preset decoding method in the original transmitted video.

[0086] S232: Add a time frame flag bit to the first color image, the second color image and the third color image according to the time frame;

[0087] The time frame flag can be a line of data added to the color image, and the information carried by the time frame flag is consistent with the time frame obtained from the decoded transmission information. The setting of the time frame flag also includes the following in S230:

[0088] S233: The color images are stored alternately in the first buffer and the second buffer;

[0089] S234: Select color images with the same time frame flag bit from the first buffer and the second buffer to form an image sequence. Figure 6 This is a schematic diagram of the buffering mechanism according to an embodiment of this application. (Reference) Figure 6 The received color image is buffered in a first buffer and a second buffer by a second digital signal processor. The second digital signal processor alternately places the received color image into the first buffer and the second buffer. For example, in... Figure 6 In this embodiment, the first channel first receives the first color image at the Nth time frame flag and places it into the second buffer. Then, it receives the first color image at the (N+1)th time frame flag and places it into the first buffer. Further, it receives the first color image at the (N+2)th time frame flag and places it into the second color image according to an alternating placement principle. The first, second, and third color images with the same time frame in the first and second buffers of the three channels are selected to align and output an image sequence.

[0090] It should be noted that, Figure 6 The second color image of the N-1th time frame flag bit in the second buffer has actually been output, but it is shown schematically for the purpose of better illustrating the method of the embodiments of this application.

[0091] In some embodiments, to better align the image sequence, the output interface of the second digital signal processor can be called at a preset period to output the first color image, the second color image, and the third color image of the time frame flag, thereby obtaining the image sequence. The preset period can be set according to the frame rate of the original transmitted video. For example, for an original transmitted image with a frame rate of 60fps, the interface can be called once every 16.7ms to output the color image, ensuring stable output from the output port of the second digital signal processor.

[0092] In other embodiments, due to internal logic of the second digital signal processor, the data in the time frame flag may be offset. For example, the time frame flag includes multiple bytes for storing data, one of which stores the data 210. Due to the influence of the second digital signal processor, when converting the encoded image into a color image, the data in this byte may shift slightly, for example, from 210 to 216. In this case, since the time frame flags attached to other color images have not changed or have changed inconsistently, the second digital signal processor cannot find a color image with the same time frame flag.

[0093] To address the aforementioned offset issue, step S232 of this application, which involves adding a time frame flag bit to the first color image, the second color image, and the third color image based on the time frame, may include: setting the Mth bit of the time frame flag bit to the first flag when the Mth byte of the time frame is greater than or equal to a first threshold; and setting the Mth bit of the time frame flag bit to the second flag when the Mth byte of the time frame is less than the first threshold.

[0094] Figure 7 This is a schematic diagram illustrating the setting of the time frame flag bit in an embodiment of this application. (Reference) Figure 7 ,exist Figure 7 The first threshold is 0, the first flag is 1, and the second flag is 0. Therefore, when the number represented by the Mth byte is greater than or equal to 0, the time frame flag is set to 1; similarly, when the number represented by the Mth byte is less than 0, the time frame flag is set to 0. For example, in... Figure 7 In the time frame, the first byte stores the data 137, which is greater than 0. Therefore, the corresponding flag in the time frame flag is set to 1. The third byte stores the data -210, which is less than 0. Therefore, the corresponding flag in the time frame flag is set to 0. By using this method, since the offset range of the time frame is small, representing one byte of the time frame with one bit can eliminate the impact of data offset during decoding on color image alignment, reducing the probability of assembly errors and preventing errors. The second digital signal processor can determine whether different color images belong to the same original transmitted image based on the time frame flag.

[0095] It is important to note that the setting of the first threshold is related to the second digital signal processor itself and the encoding method. Therefore, different first thresholds should be selected for different second digital signal processors and encoding methods to ensure that data offsets in the time frame do not exceed the first threshold. In some embodiments, since the above method is executed by a general-purpose processor, no data offset occurs, so the time frame can be directly used as the time frame flag. The first and second flags can also be freely set according to different computer systems; for example, the first flag can be 0 and the second flag can be 1.

[0096] Further, S240: Image synthesis is performed based on the image sequence to obtain the original transmitted image. The image sequence includes: the first color image, the second color image, and the third color image of the original transmitted image, including:

[0097] The first color image is converted into a first color component, and the first color component represents the brightness information of the original transmitted image;

[0098] The second color image is converted into a second color component, which represents the chromaticity information of the original transmitted image;

[0099] The third color image is converted into a third color component, which represents the density information of the original transmitted image;

[0100] The original transmitted image is obtained by synthesizing the first color component, the second color component, and the third color component.

[0101] S240 can be executed by a second logic chip, which may include three decoders. These three decoders simultaneously convert the first color image into its first color component, the second color image into its second color component, and the third color image into its third color component, thus completing the synthesis of the original transmitted image. Specifically, it can stitch together three YUV400 grayscale images to obtain a YUV444 image.

[0102] In an embodiment where a time frame flag has been added to the first color image, the second color image, and the third color image, step S240 also requires removing the time frame flag from the first color image, the second color image, and the third color image.

[0103] In S250: receiving multiple original transmitted images to generate the original transmitted video, different generation methods can be adopted according to different embodiments. In embodiments where time frames are received, the original transmitted images can be stitched together in the order of the time frames to generate the original transmitted video. In embodiments where time frames are not obtained, the original transmitted images can be sequentially generated into the original transmitted video according to the output order of S240.

[0104] Based on the aforementioned video transmission and reception methods, this application proposes a video transmission system, including a transmitter and a receiver. The transmitter includes a first logic chip, a first digital signal processor, and a first main processor. The receiver includes a second digital processor, a second main processor, and a second logic chip. The first main processor is connected to the first logic chip and the first digital signal processor, respectively. The second main processor is connected to the second logic chip and the second digital signal processor, respectively. The first main processor and the second main processor are communicatively connected. The first logic chip is used to obtain an original transmitted image based on the original transmitted video and convert the original transmitted image into a preset image format to obtain a converted transmitted image. The first logic chip is also used to split the converted transmitted image according to color information to obtain multiple color images, including a first color image, a second color image, and a third color image. The first digital signal processor is used to encode the multiple color images according to a preset encoding method to obtain a first encoded image of the first color image, a second encoded image of the second color image, and a third encoded image of the third color image. The first main processor is used to... The system converts a first coded image, a second coded image, and a third coded image into transmission information. The first main processor is further configured to send the transmission information to the receiving end, enabling the receiving end to obtain the original transmission image and the original transmission video based on the transmission information. The second main processor is configured to receive the transmission information and extract multiple coded images from it, including the first coded image, the second coded image, and the third coded image. The second digital signal processor is configured to decode each coded image according to a preset decoding method to obtain a color image, including the first color image of the first coded image, the second color image of the second coded image, and the third color image of the third coded image. The second digital signal processor is further configured to store the multiple color images in a buffer and perform image alignment on the color images in the buffer to obtain at least one image sequence. The second logic chip is configured to synthesize the images based on the image sequence to obtain the original transmission image, including the first color image, the second color image, and the third color image of the original transmission image. The second logic chip is further configured to receive multiple original transmission images to generate the original transmission video. This video transmission system can be integrated with... Figure 1 This corresponds to the video transmission system.

[0105] In one embodiment of the above implementation, the original transmitted video is converted into a YUV444 image, and then split into three color components (Y, U, V) to form three corresponding YUV400 images. These images are then encoded in grayscale and transmitted. At the receiving end, the images are decoded and reassembled to generate a new YUV444 image. This reduces the bitrate and ensures that the original transmitted video output at the receiving end is visually lossless. Furthermore, the above implementation can be achieved using existing digital signal processors and logic chips, eliminating the need for additional decoding chips and reducing costs. Further, by setting a time frame flag, the logic problem at the receiving end when stitching YUV400 images is solved, increasing stitching speed and reducing the probability of stitching errors. Additionally, by using one bit of the time frame flag to represent one byte of the time frame, the data offset problem caused by decoding in the logic chip is eliminated.
