Technical Field

[0002] The present application relates to the field of video, and in particular to a video frame processing method and related equipment. Background Art

[0003] Current mainstream TVs and set-top boxes are equipped with image quality processing technology, the main purpose of which is to improve the image quality of the playback content, such as clarity, contrast, color performance, noise suppression, etc.

[0004] When a TV and set-top box are connected, the front-end set-top box processes the video source. The set-top box and TV are connected via a high-definition multimedia interface (HDMI) cable. After receiving the processed image from the set-top box via the HDMI cable, the back-end TV typically also processes the image quality. This double processing, performed by the set-top box and the TV, can cause side effects and degrade the visual quality.

[0005] Summary of the Invention

[0006] The embodiments of the present application provide a video frame processing method and related equipment, and the use of the embodiments of the present application is conducive to improving the display quality of video frames.

[0007] In a first aspect, an embodiment of the present application provides a video frame processing method, which is applied to a first video processing device.

[0008] The first video processing device obtains the first video frame and the capability information of the second video processing device, the capability information including the first picture quality algorithm supported by the second video processing device and the first level of the first picture quality algorithm. The higher the level of the first picture quality algorithm, the higher the display quality of the video frame processed using the first picture quality algorithm; the first video processing device traverses the picture quality algorithms supported by the first video processing device according to the first picture quality algorithm, and when it is determined that the first video processing device supports the first picture quality algorithm, obtains the second level of the first picture quality algorithm supported by the first video processing device; if the first level of the first picture quality algorithm supported by the second video processing device is not lower than the second level of the first picture quality algorithm supported by the first video processing device, the first video processing device processes the first video frame according to the first picture quality algorithm of the third level, and the third level is not higher than the second level of the first picture quality algorithm supported by the first video processing device.

[0009] The first video processing device determines the appropriate level of image quality algorithm to process the first video frame by comparing the level of the image quality algorithm supported by the first video processing device with the level of the image quality algorithm supported by the second video processing device, which helps to avoid excessive processing of the video frame and thereby improve the display quality of the video frame.

[0010] In combination with the first aspect, in one possible implementation, if the first level of the first image quality algorithm supported by the second video processing device is lower than the second level of the first image quality algorithm supported by the first video processing device, the first video processing device processes the first video frame according to the first image quality algorithm of the second level.

[0011] The first video processing device determines the appropriate level of image quality algorithm to process the first video frame by comparing the level of the image quality algorithm supported by the first video processing device with the level of the image quality algorithm supported by the second video processing device. This is beneficial to avoid excessive processing of the video frame and to improve the display quality of the video frame.

[0012] In combination with the first aspect, in one possible implementation, the first image quality algorithm is a clarity enhancement algorithm, a contrast enhancement algorithm, a color enhancement algorithm or a noise reduction algorithm, and the display quality of the video frame processed using the first image quality algorithm is characterized by the clarity, contrast, color vividness or noise of the video frame.

[0013] In combination with the first aspect, in one possible implementation, the first video processing device sends processing method information and a second video frame to the second video processing device. The processing method information includes the image quality algorithm and its level used by the first video processing device to process the first video frame. The second video frame is obtained by the first video processing device processing the first video frame using the supported image quality algorithm.

[0014] By sending processing method information to the second video processing device, the second video processing device can obtain the image quality algorithm and its level used by the first video processing device to process the first video frame, thereby determining the appropriate level of image quality algorithm to process the second video frame, avoiding excessive processing, and thereby improving the display quality of the video frame.

[0015] In a second aspect, an embodiment of the present application provides another video frame processing method, which is applied to a second video processing device.

[0016] The second video processing device obtains a second video frame and processing method information. The second video frame is obtained by the first video processing device using a supported image quality algorithm to process the first video frame. The processing method information includes the second image quality algorithm used by the first video processing device to process the first video frame and the first level of the second image quality algorithm; the higher the level of the second image quality algorithm, the higher the display quality of the video frame processed using the second image quality algorithm; the second video processing device traverses the image quality algorithms supported by the second video processing device, and when it is determined that the second video processing device supports the second image quality algorithm, obtains the second level of the second image quality algorithm supported by the second video processing device; if the second level of the second image quality algorithm supported by the second video processing device is higher than the first level of the second image quality algorithm used by the first video processing device to process the first video frame, and the first level is not 0, the second video processing device uses a second image quality algorithm of the third level to process the second video frame, and the third level is lower than the second level of the second image quality algorithm supported by the second video processing device.

[0017] Before processing the second video frame, the second video processing device determines a suitable level of image quality algorithm to process the second video frame by comparing the level of the image quality algorithm used by the first video processing device when processing the first video frame with the level of the image quality algorithm supported by the second video processing device. This is beneficial to avoid excessive processing of the video frame, thereby improving the display quality of the video frame.

[0018] In combination with the second aspect, in one possible implementation, if the second level of the second image quality algorithm supported by the second video processing device is higher than the first level of the second image quality algorithm used by the first video processing device to process the first video frame, and the first level is 0, the second video processing device uses the second image quality algorithm of the second level to process the second video frame; the first level of the second image quality algorithm is 0, indicating that the first video processing device does not use the second image quality algorithm to process the first video frame.

[0019] When the first video processing device does not use the second image quality algorithm to process the first video frame, the second video processing device uses the second image quality algorithm to process the second video frame, which is beneficial to improving the display quality of the video frame.

[0020] In combination with the second aspect, in one possible implementation, if the second level of the second image quality algorithm supported by the second video processing device is not higher than the first level of the second image quality algorithm used by the first video processing device to process the first video frame, the second video processing device uses a second image quality algorithm with a level of 0 to process the second video frame, thereby avoiding excessive processing and reducing the display quality of the video frame; wherein, the level of the second image quality algorithm is 0, indicating that the second video processing device does not use the second image quality algorithm to process the second video frame.

[0021] In combination with the second aspect, in one possible implementation, the second image quality algorithm is a clarity enhancement algorithm, a contrast enhancement algorithm, a color enhancement algorithm or a noise reduction algorithm, and the display quality of the video frame processed using the second image quality algorithm is characterized by the clarity, contrast, color vividness or noise of the processed video frame.

[0022] In combination with the second aspect, in one possible implementation, the second video processing device packages the image quality algorithms and their levels supported by the second video processing device into the capability information of the second video processing device, so that the first video processing device obtains the image quality algorithms and their levels supported by the second video processing device, thereby determining the appropriate level of image quality algorithm to process the video frame, thereby improving the display quality of the video frame.

[0037] The terms "first", "second", "third" and "fourth" in the specification, claims and drawings of this application are used to distinguish different objects rather than to describe a specific order.

[0038] "Multiple" refers to two or more. "And / or" describes the relationship between related objects, indicating the existence of three relationships. For example, "A and / or B" means: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally indicates that the related objects are in an "or" relationship.

[0039] The embodiments of the present application are described below with reference to the accompanying drawings.

[0040] 1 , which is a schematic diagram of a system architecture provided by an embodiment of the present application. As shown in FIG1 , the system architecture includes a first video processing device 101 and a second video processing device 102 .

[0041] The first video processing device 101 is connected to the second video processing device 102 via an interconnection interface. Optionally, the interconnection interface is HDMI, display port (DP) or other high-speed video interface.

[0042] The first video processing device 101 is a device capable of processing and outputting video signals, and the second video processing device 102 is a device capable of receiving, processing, and outputting video signals. Optionally, the first video processing device 101 is a set-top box, a split TV (box end), a smart mid-screen, a set-top box with a screen, a smart speaker, etc.; the second video processing device 102 is a TV, a split TV (TV end), a monitor, a large-screen device, etc.

[0043] Optionally, the first video processing device 101 and the second video processing device 102 are connected in a wired manner or a wireless manner.

[0044] The first video processing device 101 obtains a first video frame and obtains capability information of the second video processing device 102 from the second video processing device 102, where the capability information includes an image quality algorithm supported by the second video processing device 102 and the level of the image quality algorithm; wherein, a higher level of the image quality algorithm, a higher display quality of the video frame processed using the image quality algorithm; the first video processing device 101 processes the first video frame according to the image quality algorithm and its level supported by the first video processing device 101 and the image quality algorithm and its level supported by the second video processing device 102 to obtain a second video frame; the first video processing device 101 transmits the second video frame and the image quality algorithm and its level used to process the first video frame to the second video processing device 102.

[0045] The second video processing device 102 processes the second video frame according to the image quality algorithm and its level adopted by the first video processing device 101 to process the first video frame, and the image quality algorithm and its level supported by the second video processing device 102; the second video processing device 102 displays the processed second video frame, or transmits the processed second video frame to a display device (not shown in Figure 1).

[0046] It can be seen that the first video processing device 101 and the second video processing device 102 process the video frames through negotiation, such as clarity enhancement processing, contrast enhancement processing, color enhancement processing, noise reduction processing, etc., which is conducive to improving the display quality of the video frames.

[0047] Referring to FIG2 , FIG2 is a flow chart of a video frame processing method provided in an embodiment of the present application. The method is applied to the first video processing device 101 in FIG1 . As shown in FIG2 , the method includes:

[0048] S201: A first video processing device obtains capability information of a second video processing device and a first video frame.

[0049] The capability information of the second video processing device includes the image quality algorithms supported by the second video processing device and their levels. The higher the level of the image quality algorithm, the higher the display quality of the video frame processed by the image quality algorithm.

[0050] In an example, the first video frame obtained by the first video processing device is obtained by the first video processing device from another device, or obtained from a local storage of the first video processing device.

[0051] In one example, when the interconnection interface is an HDMI interface, the capability information of the second video processing device is extended display identification data (EDID) information. When the first video processing device and the second video processing device perform an HDMI handshake, the first video processing device obtains the EDID information from the second video processing device and parses it to obtain the image quality algorithm and its level supported by the second video processing device. Of course, when the interconnection interface is DP, the capability information of the second video processing device is the information corresponding to DP, such as displayID information or EDID information. It should be understood that the interconnection interface can of course also be other high-speed video interfaces.

[0052] In one possible embodiment, the image quality algorithm includes but is not limited to a clarity enhancement algorithm, a contrast enhancement algorithm, a color enhancement algorithm, and a noise reduction algorithm; correspondingly, the display quality of the video frame processed by the image quality algorithm is characterized by the clarity, contrast, color vividness and noise of the processed video frame.

[0053] In one example, the image quality algorithms here are classified according to their functions, that is, the image quality algorithms include a class of image quality algorithms that implement the same function. This class of image quality algorithms includes a variety of specific image quality algorithms, and these specific image quality algorithms have corresponding levels. The level of the image quality algorithm supported by the video processing device (including the first video processing device and the second video processing device) refers to the maximum value of the level of this class of image quality algorithms. For example, the first image quality algorithm is used to enhance clarity, and the first image quality algorithm includes a first clarity enhancement algorithm, a second clarity enhancement algorithm, and a third clarity enhancement algorithm. Among them, the level of the first clarity enhancement algorithm is 1, the level of the second clarity enhancement algorithm is 2, and the level of the third clarity enhancement algorithm is 3. At this time, the level of the first image quality algorithm supported by the video processing device is 3.

[0054] It should be understood that the implementation logic of multiple specific image quality algorithms included in a category of image quality algorithms may be the same or different. For multiple specific image quality algorithms with the same implementation logic, the display quality of the video frames obtained using the specific image quality algorithm is adjusted by modifying the parameters in the specific image quality algorithm based on the specific image quality algorithm, thereby obtaining specific image quality algorithms of different levels.

[0055] In one example, the levels of the image quality algorithm are divided into 0, 1, 2, 3, 4, and 5. The larger the number, the higher the level. 0 means that the image quality algorithm is turned off, or it can be understood that the image quality algorithm is not used to process the video frame. In a specific example, the image quality algorithm is a clarity enhancement algorithm; when the clarity of the video frame processed by the image quality algorithm is higher than the first threshold and not higher than the second threshold, the level of the image quality algorithm is 1; when the clarity of the video frame processed by the image quality algorithm is higher than the second threshold and not higher than the third threshold, the level of the image quality algorithm is 2; when the clarity of the video frame processed by the image quality algorithm is higher than the third threshold and not higher than the fourth threshold, the level of the image quality algorithm is 3.

[0056] In another example, the image quality algorithm here is a specific algorithm for implementing a function.

[0057] It should be understood that the second video processing device may support one or more image quality algorithms, that is, the second video processing device supports one or more image quality processing on video frames.

[0058] S202: The first video processing device traverses the image quality algorithms supported by the first video processing device, and when it is determined that the first video processing device supports the first image quality algorithm, obtains a second level of the first image quality algorithm supported by the first video processing device.

[0059] The image quality algorithm supported by the second video processing device includes a first image quality algorithm, and the level of the first image quality algorithm is level 1. It should be understood that the first image quality algorithm is one of the image quality algorithms supported by the second video processing device.

[0060] Specifically, the first video processing device traverses the image quality algorithms supported by the first video processing device according to the first image quality algorithm to determine whether the first video processing device supports the first image quality algorithm; if it is determined that the first video processing device supports the first image quality algorithm, that is, the first video processing device and the second video processing device both have functions corresponding to the first image quality algorithm, then the first video processing device obtains the second level of the first video processing device's support for the first image quality algorithm.

[0061] S203. When the first level of the first image quality algorithm supported by the second video processing device is not lower than the second level of the first image quality algorithm supported by the first video processing device, the first video processing device processes the first video frame based on the first image quality algorithm of the third level.

[0062] Among them, the third level is not higher than the second level.

[0063] Specifically, the first video processing device processes the first video frame based on the first image quality algorithm of the third level, including three situations:

[0064] 1. The first video processing device processes the first video frame based on a first image quality algorithm of the second level;

[0065] 2. The first video processing device uses a first image quality algorithm with a level of 0 to process the first video frame, that is, the first video processing device turns off the first image quality algorithm and does not perform processing corresponding to the first image quality algorithm on the video frame; for example, the first image quality algorithm is a contrast enhancement algorithm, and the first video processing device does not perform processing corresponding to the first image quality algorithm on the first video frame, which means that the first video processing device does not perform contrast enhancement processing on the first video frame.

[0066] It should be understood that not performing the processing corresponding to the first image quality algorithm on the first video frame is a special way of processing the first video frame using the first image quality algorithm, which is to process the first video frame using the first image quality algorithm with level 0.

[0067] 3. The first video processing device selects a first picture quality algorithm whose level is lower than the second level and higher than 0 to process the first video frame, or adjusts parameters in the first picture quality algorithm whose level is the second level so that the display quality of the video frame processed by the first picture quality algorithm after adjusting the parameters is lower than the display quality of the video frame processed by the first picture quality algorithm whose level is the second level, and processes the first video frame using the first picture quality algorithm after adjusting the parameters.

[0068] When the first level of the first image quality algorithm supported by the second video processing device is lower than the second level of the first image quality algorithm supported by the first video processing device, the first video processing device processes the first video frame according to the first image quality algorithm of the second level. The processing effect of the first video processing device on the first image quality algorithm is better than that of the second video processing device, so the first video processing device uses the first image quality algorithm of the highest level to process the first video frame to improve the display quality of the video frame.

[0069] If it is determined that the first video processing device does not support the first image quality algorithm, the first video processing device traverses the image quality algorithms supported by the first video processing device according to other image quality algorithms supported by the second video processing device until the first video processing device has traversed all image quality algorithms supported by the first video processing device using all image quality algorithms supported by the second video processing device.

[0070] In one possible implementation, when it is determined that the first video processing device supports the third image quality algorithm and the second video processing device does not support the third image quality algorithm, the first video processing device processes the second video frame based on the first video processing device's support for the third image quality algorithm, and the first video processing device selects a level other than 0 for the adopted third image quality algorithm. The function of the third image quality algorithm is different from that of the first image quality algorithm.

[0071] In the above manner, the first video processing device processes the first video frame using a supported image quality algorithm to obtain a second video frame. For example, if the image quality algorithm supported by the first video processing device includes a contrast enhancement algorithm and a noise reduction algorithm, the first video processing device performs contrast enhancement and noise reduction processing on the first video frame using the contrast enhancement and noise reduction algorithms determined in the above manner to obtain the second video frame.

[0072] In one possible implementation, before adopting the first image quality algorithm to process the first video frame, the first video processing device determines whether it is necessary to adopt the first image quality algorithm to process the first video frame. Specifically, the first video processing device determines whether the display quality corresponding to the first image quality algorithm of the first video frame meets the preset requirements. If not, the first video processing device adopts the first image quality algorithm to process the first video frame; if so, the first video processing device does not adopt the first image quality algorithm to process the first video frame, thereby avoiding excessive processing and reducing the display quality of the video frame. In one example, the first image quality algorithm is a contrast enhancement algorithm. If the contrast of the first video frame is less than the contrast threshold, it is determined to adopt the first image quality algorithm to process the first video frame; if the contrast of the first video frame is not less than the contrast threshold, the first video processing device does not adopt the first image quality algorithm to process the first video frame.

[0073] S204: The first video processing device sends the second video frame and processing mode information to the second video processing device.

[0074] The second video frame is obtained by processing the first video frame by the first video processing device using a supported image quality algorithm.

[0075] Specifically, after the second video frame, the first video processing device packages the image quality algorithm and its level used by the first video processing device to process the first video frame into processing mode information. After a path (e.g., an HDMI path) is established between the first video processing device and the second video processing device, the first video processing device sends the second video frame and the corresponding processing mode information to the second video processing device, thereby informing the second video processing device of the image quality algorithm and its level used by the first video processing device for the first video frame.

[0076] It should be noted that the first video processing device processes each acquired video frame in the above manner, which will not be described again here.

[0077] It should be noted that when the interconnection interface between the first video processing device and the second video processing device is HDMI, the processing mode information is packaged in the information frame packet. When the interconnection interface is DP, the processing mode information is packaged in the information frame packet or the auxiliary packet. Of course, the interconnection interface can also be other high-speed video interfaces.

[0078] In a specific embodiment, the first video processing device is a set-top box and the second video processing device is a television. As shown in FIG3 :

[0079] S301: The set-top box obtains EDID information from the TV and parses the EDID information to obtain the image quality algorithm and level supported by the TV.

[0080] S302: The set-top box traverses the image quality algorithms supported by the TV.

[0081] S303: Check whether the set-top box has traversed all the image quality algorithms supported by the TV.

[0082] If the set-top box has not yet completed the traversal of the image quality algorithms supported by the television, the set-top box executes S304. If the set-top box has completed the traversal of the image quality algorithms supported by the television, the process of determining the image quality algorithm and its level to be used for processing the video frame ends. The set-top box processes the first video frame using the image quality algorithm and its level determined in the manner described in FIG3 to obtain a second video frame. The image quality algorithm and level used to process the first video frame are packaged into an information frame packet, and the information frame packet and the second video frame are transmitted to the television.

[0083] The television may support one or more picture quality algorithms, and the set-top box may support one or more picture quality algorithms.

[0084] S304: The set-top box determines whether the set-top box supports the first image quality algorithm.

[0085] The set-top box traverses the picture quality algorithms supported by the TV. For the first picture quality algorithm supported by the TV, the set-top box determines whether the set-top box supports the first picture quality algorithm. If the set-top box supports the first picture quality algorithm, the set-top box obtains the second level of the first picture quality algorithm supported by the set-top box and executes S305. If the set-top box does not support the first picture quality algorithm, the set-top box executes S302.

[0086] S305: The set-top box determines whether the first level of the first image quality algorithm supported by the television is not lower than the second level of the first image quality algorithm supported by the set-top box.

[0087] When the first level of the first picture quality algorithm supported by the TV is not lower than the second level of the first picture quality algorithm supported by the set-top box, the set-top box executes S307; when the first level of the first picture quality algorithm supported by the TV is lower than the second level of the first picture quality algorithm supported by the set-top box, the set-top box executes S306.

[0088] S306: The set-top box starts the first image quality algorithm normally.

[0089] It should be understood that the set-top box normally turns on the first picture quality algorithm, which means that when the set-top box uses the second-level first picture quality algorithm to process the first video frame, it does not adjust the parameters in the first picture quality algorithm, thereby achieving the goal of not reducing the display quality of the second video frame processed using the first picture quality algorithm.

[0090] S307: The set-top box turns off, weakens, or normally starts the first image quality algorithm.

[0091] It should be understood that the set-top box turning off the first picture quality algorithm means that the set-top box does not use the first picture quality algorithm to process the first video frame; the set-top box weakening the first picture quality algorithm means that when the set-top box uses the first picture quality algorithm to process the first video frame, it adjusts the parameters in the first picture quality algorithm to lower the level of the first picture quality algorithm, or selects a picture quality algorithm with a level lower than the second level to process the first video frame, so as to achieve the purpose of reducing the display quality of the second video frame processed by the first picture quality algorithm.

[0092] There are three image quality processing methods shown in S307: turning off the first image quality algorithm, weakening the first image quality algorithm, and normally turning on the first image quality algorithm. When it is determined to use the S307 method to process the video frame, the set-top box can choose one of the three methods to process the video frame for subsequent received video frames; for different video frames, the image quality processing methods used can be the same or different.

[0093] After executing S306 and S307, the set-top box executes S302.

[0094] It can be seen that in the solution of the present application, the first video processing device determines the appropriate level of image quality algorithm to process the video frame by comparing the level of the image quality algorithm supported by the first video processing device with the level of the image quality algorithm supported by the second video processing device, which is conducive to avoiding excessive processing of the video frame and thereby improving the display quality of the video frame.

[0095] Referring to FIG4 , FIG4 is a flow chart of another video frame processing method provided in an embodiment of the present application. The method is applied to the second video processing device 102 in FIG1 . As shown in FIG4 , the method includes:

[0096] S401: A second video processing device obtains a second video frame and processing mode information.

[0097] The second video frame is obtained by processing the first video frame using a supported image quality algorithm by the first video processing device. The processing mode includes the image quality algorithm used by the first video processing device to process the first video frame and its corresponding level. The second image quality algorithm is one of the image quality algorithms used by the first video processing device to process the first video frame. The higher the level of the second image quality algorithm, the higher the display quality of the video frame processed using the second image quality algorithm.

[0098] In one example, after a path is established between a first video processing device and a second video processing device, the second video processing device receives a second video frame and corresponding processing method information, and parses the processing method information to obtain the image quality algorithm and its level adopted by the first video processing device for the first video frame.

[0099] In one example, image quality algorithms include, but are not limited to, clarity enhancement algorithms, contrast enhancement algorithms, color enhancement algorithms, and noise reduction algorithms. Accordingly, the display quality of video frames processed using these image quality algorithms is characterized by the clarity, contrast, color vividness, and noise of the processed video frames. It should be understood that the image quality algorithms herein are categorized by function.

[0100] In one example, the levels of the image quality algorithm are divided into 0, 1, 2, 3, 4, and 5. The larger the number, the higher the level. 0 means turning off the image quality algorithm or it can be understood that the image quality algorithm is not used to process the video frame. In a specific example, the image quality algorithm is a clarity enhancement algorithm; when the clarity of the video frame processed by the image quality algorithm is higher than the first threshold and not higher than the second threshold, the level of the image quality algorithm is 1; when the clarity of the video frame processed by the image quality algorithm is higher than the second threshold and not higher than the third threshold, the level of the image quality algorithm is 2; when the clarity of the video frame processed by the image quality algorithm is higher than the third threshold and not higher than the fourth threshold, the level of the image quality algorithm is 3.

[0101] S402: The second video processing device traverses the image quality algorithms supported by the second video processing device, and when it is determined that the second video processing device supports the second image quality algorithm, obtains a second level of the second image quality algorithm supported by the second video processing device.

[0102] The image quality algorithm used by the first video processing device to process the first video frame includes a second image quality algorithm, and the level of the second image quality algorithm is the first level.

[0103] It should be understood that the image quality algorithms here are classified according to function, that is, the image quality algorithms include a class of image quality algorithms that implement the same function, and the level of the image quality algorithm supported by the second video processing device refers to the maximum level of this class of image quality algorithms.

[0104] Specifically, the second video processing device traverses the image quality algorithms supported by the second video processing device according to the second image quality algorithm to determine whether the second video processing device supports the second image quality algorithm; if it is determined that the second video processing device supports the second image quality algorithm, the second video processing device obtains the second level of support for the second image quality algorithm by the second video processing device.

[0105] S403. If the second level of the second image quality algorithm supported by the second video processing device is higher than the first level of the second image quality algorithm used by the first video processing device to process the first video frame, and the first level is not 0, the second video processing device uses a second image quality algorithm of a third level to process the second video frame, wherein the third level is lower than the second level.

[0106] Specifically, the second video processing device processes the second video frame based on the second image quality algorithm of the third level, including three situations:

[0107] 1. The second video processing device processes the second video frame based on a second image quality algorithm with a second level;

[0108] 2. The second video processing device uses a second image quality algorithm with a level of 0 to process the second video frame, that is, the second video processing device turns off the second image quality algorithm and does not perform processing corresponding to the second image quality algorithm on the second video frame; for example, the second image quality algorithm is a contrast enhancement algorithm, and the first video processing device does not perform processing corresponding to the second image quality algorithm on the second video frame, which means that the second video processing device does not perform contrast enhancement processing on the second video frame.

[0109] It should be understood that not performing the processing corresponding to the second image quality algorithm on the second video frame is a special way of processing the second video frame using the second image quality algorithm, and is processing the second video frame using the second image quality algorithm with level 0.

[0110] 3. The second video processing device selects a second image quality algorithm whose level is lower than the second level and higher than 0 to process the second video frame, or adjusts the parameters in the second image quality algorithm whose level is the second level, so that the display quality of the video frame processed by the second image quality algorithm after adjusting the parameters is lower than the display quality of the video frame processed by the second image quality algorithm whose level is the second level, and processes the second video frame using the second image quality algorithm after adjusting the parameters.

[0111] In one possible implementation, if the second level of the second image quality algorithm supported by the second video processing device is higher than the first level of the second image quality algorithm used by the first video processing device to process the first video frame, and the first level is 0, the second video processing device uses the second image quality algorithm of the second level to process the second video frame. It should be understood that the fact that the first level of the second image quality algorithm used by the first video processing device to process the first video frame is 0 essentially means that the first video processing device does not use the second image quality algorithm to process the first video frame. Since the first video processing device does not use the second image quality algorithm to process the first video frame, the second video processing device can choose to use the second image quality algorithm of the second level to process the video frame to enhance the display quality of the video frame.

[0112] In one possible implementation, if the second level of the second image quality algorithm supported by the second video processing device is not higher than the first level of the second image quality algorithm used by the first video processing device to process the first video frame, the second video processing device uses a second image quality algorithm with a level of 0 to process the second video frame, that is, the second video processing device does not use the second image quality algorithm to process the second video frame. Since the level of the second image quality algorithm supported by the second video processing device is lower than the level of the second image quality algorithm used by the first video processing device to process the first video frame, that is, the first video processing device can process the display quality of the first video frame very well, and the second video processing device does not need to perform further processing on the processing result of the first video processing device, the second video processing device does not need to use the second image quality algorithm to process the second video frame.

[0113] In one possible implementation, if it is determined that the second video processing device does not support the second image quality algorithm, the second video processing device traverses the image quality algorithms supported by the second video processing device according to other image quality algorithms used by the first video processing device to process the first video frame, until the second video processing device has traversed the image quality algorithms supported by the second video processing device using all image quality algorithms used by the first video processing device to process the first video frame.

[0114] In one possible implementation, when the image quality algorithm used by the first video processing device to process the first video frame does not include the fourth image quality algorithm, and the second video processing device supports the fourth image quality algorithm, the second video processing device processes the second video frame based on the fourth image quality algorithm. The second video processing device may select a level other than 0 for the fourth image quality algorithm. The function of the fourth image quality algorithm is different from that of the second image quality algorithm.

[0115] In one possible implementation, before using the second image quality algorithm to process the second video frame, the second video processing device determines whether the second image quality algorithm needs to be used to process the second video frame. Specifically, the second video processing device determines whether the display quality corresponding to the second image quality algorithm of the second video frame meets preset requirements. If not, the second video processing device processes the second video frame using the second image quality algorithm; if so, the second video processing device does not process the second video frame using the second image quality algorithm, thereby avoiding excessive processing that may degrade the display quality of the video frame.

[0116] In one possible implementation, the method of the present application further includes:

[0117] The second video processing device packages the image quality algorithms and their levels supported by the second video processing device into the capability information of the second video processing device, so that the first video processing device can obtain the image quality algorithms and their levels supported by the second video processing device, thereby determining the appropriate level of image quality algorithm to process the video frame, thereby improving the display quality of the video frame.

[0118] In a specific embodiment, the first video processing device is a set-top box and the second video processing device is a television. As shown in FIG5 :

[0119] S501: A television receives an information frame packet and a second video frame from a set-top box, and parses the information frame packet to obtain an image quality algorithm and level used by the set-top box to process the first video frame.

[0120] S502: The television traverses the image quality algorithm used by the set-top box to process the first video frame.

[0121] S503: Whether the television has traversed the image quality algorithm used by the set-top box to process the first video frame.

[0122] If the television has not yet completed the image quality algorithm used by the set-top box to process the first video frame, the television executes S504. If the television has completed the image quality algorithm used by the set-top box to process the first video frame, the television ends the process of determining the image quality algorithm and its level to be used for processing the video frame. The television processes the second video frame using the image quality algorithm and its level determined in the manner shown in FIG5.

[0123] The television may support one or more picture quality algorithms, and the set-top box may use one or more picture quality algorithms to process video frames.

[0124] S504: The TV determines whether the TV supports the second image quality algorithm.

[0125] The TV traverses the picture quality algorithms used by the set-top box to process the video frames. For the second picture quality algorithm used by the set-top box to process the video frames, the TV determines whether the TV supports the second picture quality algorithm. If the TV supports the second picture quality algorithm, the TV box obtains the second level of the second picture quality algorithm supported by the TV and executes S505. If the TV does not support the first picture quality algorithm, the TV executes S502.

[0126] S505: The television determines whether the second level of the second image quality algorithm supported by the television is higher than the first level of the second image quality algorithm used by the set-top box to process the first video frame.

[0127] If the second level of the second picture quality algorithm supported by the TV is not higher than the first level of the second picture quality algorithm used by the set-top box to process the first video frame, the TV executes step S506; if the second level of the second picture quality algorithm supported by the TV is higher than the first level of the second picture quality algorithm used by the set-top box to process the first video frame, the TV executes step S507.

[0128] S506: The television turns off the second image quality algorithm.

[0129] It should be understood that turning off the second image quality algorithm by the television means that the television does not use the second image quality algorithm to process the second video frame.

[0130] S507: The television determines whether the level of the second image quality algorithm used by the set-top box to process the first video frame is 0.

[0131] If the level of the second image quality algorithm used by the top box to process the first video frame is 0, the TV executes S508; if the level of the second image quality algorithm used by the top box to process the first video frame is not 0, the TV executes S509.

[0132] S508: The TV starts the second image quality algorithm normally.

[0133] It should be understood that the TV normally turns on the second picture quality algorithm, which means that when the TV uses the second-level second picture quality algorithm to process the second video frame, it does not adjust the parameters in the second picture quality algorithm, thereby achieving the goal of not reducing the display quality of the video frame processed using the second picture quality algorithm.

[0134] S509: The TV adjusts the second image quality algorithm to a weaker level.

[0135] It should be understood that the TV weakening the second picture quality algorithm means that when the TV uses the second picture quality algorithm to process the second video frame, it adjusts the parameters in the second picture quality algorithm, or selects a second picture quality algorithm with a level lower than the second level, thereby reducing the display quality of the video frame processed by the second picture quality algorithm.

[0136] After executing S506 , S508 , and S509 , the TV executes S502 .

[0137] It can be seen that in the solution of the present application, before processing the second video frame, the second video processing device determines the appropriate level of image quality algorithm to process the second video frame by comparing the level of the image quality algorithm used by the first video processing device when processing the video frame with the level of the image quality algorithm supported by the second video processing device, which is conducive to avoiding excessive processing of the video frame and thereby improving the display quality of the video frame.

[0138] It should be understood that this application uses the image quality algorithm as an example to illustrate that the first video processing device and the second video processing device adjust the display quality of the video frame in an adaptive manner provided by this application. The protection scope of this application is not limited to the image quality algorithm disclosed in this application, and other strategies that change the display quality of the video frame also fall within the protection scope of this application.
