Referring to fig. 4, a flowchart of a video playback device according to another embodiment of the present application is shown, where the method may be applied to the video playback system shown in fig. 1, and the method may include the following steps:
step 401, a video playing device acquires a video image.
Step 402, the video playing device sends the video image to the mobile terminal.
Accordingly, the mobile terminal receives the video image from the video playing device.
For the description of steps 401 to 402, reference may be made to the above embodiments, which are not described herein again.
In step 403, the video playing device obtains image quality data, where the image quality data is data related to image quality collected during the process of watching the video playing device.
The video playing device can acquire image quality data within a preset time period, and the preset time period can be a default time period or a time period set by a user, which is not limited by the embodiment of the application. For example, the image quality data may be data related to image quality such as image sharpness, brightness, and contrast, and the type of the image quality data is not limited in the embodiments of the present application.
In step 404, the video playing device constructs an image quality image based on the image quality data, wherein the image quality image is used for representing image quality characteristics when the video playing device is watched, and the image quality image is used for performing image quality processing on the video image.
In a possible implementation, the portrait dimensions of the image quality portrait may include at least one of: sharpness preference, brightness preference, contrast preference, eye-protection preference, and the like. The definition preference refers to definition of frequently viewed video, for example, frequently viewed video with definition 480p, frequently viewed video with definition 720p, frequently viewed video with definition 1080p, and the like; the brightness preference refers to the brightness of the frequently viewed video, for example, the frequently viewed video with lower brightness, the frequently viewed video with higher brightness, and the like; the contrast preference refers to the contrast of frequently viewed videos, for example, videos with higher contrast are frequently viewed, videos with lower contrast are frequently viewed, and the like; eye protection preference refers to a normally open eye protection mode or a normally unopened eye protection mode. The embodiment of the application can set corresponding numerical values for the preferences, for example, a video with 480p of frequent watching definition corresponds to 0, a video with 720p of frequent watching definition corresponds to 1, and a video with 1080p of frequent watching definition corresponds to 2; the video with lower brightness is frequently watched and corresponds to 0, and the video with higher brightness is frequently watched and corresponds to 1; the video with higher contrast is watched frequently and corresponds to 0, and the video with lower contrast is watched frequently and corresponds to 1; the normally open eye protection mode corresponds to 0, and the normally open eye protection mode corresponds to 1.
In a possible implementation, the image quality representation may be presented in the form of a vector. For example, if the temperature of the image quality portrait includes a definition preference and a brightness preference, the definition preference is that a video with a definition of 1080p is frequently viewed, and the brightness preference is that a video with a lower brightness is frequently viewed, the image quality portrait may be represented as [2, 0 ].
Step 405, the video playing device sends the image quality portrait to the mobile terminal.

Correspondingly, the mobile terminal receives the image quality image from the video playing device, the image quality image is used for representing image quality characteristics when the video playing device is watched, and the image quality image is used for performing image quality processing on the video image.
In a possible implementation manner, step 405 may be executed simultaneously with step 402, that is, the video playing device may simultaneously transmit the video image and the image quality representation to the mobile terminal.
In a possible implementation manner, the video playing device may first perform step 405 and then perform step 402, that is, the video playing device may first send the image quality representation to the mobile terminal and then send the video image to the mobile terminal.
In a possible implementation manner, the video playing device may first perform step 402 and then perform step 405, that is, the video playing device may first send the video image to the mobile terminal, and then send the image quality representation to the mobile terminal.
The execution sequence of steps 402 and 405 is not limited in the embodiment of the present application.
And step 406, the mobile terminal performs image quality processing on the video image based on the image quality image to obtain a processed video image.
Wherein the processed video image is matched with the image quality portrait.
Still taking the above example as an example for explanation, assuming that the image quality image is [2, 0], the resolution of the processed video image obtained by the mobile terminal is 1080p, and the brightness is low.
Step 407, the mobile terminal sends the processed video image to the video playing device.
In a possible implementation manner, the mobile terminal sends the processed video image to the video playing device in a wired manner. For example, the mobile terminal sends the processed video image to a video playing device through a patch cord.
In a possible implementation manner, the mobile terminal sends the processed video image to the video playing device in a wireless manner. For example, the mobile terminal sends the processed video image to a video playing device through a network.
Accordingly, the video playing device receives the processed video image from the mobile terminal, and the image quality of the processed video image is higher than that of the video image.
In step 408, the video playing device plays the processed video image.
To sum up, in the technical scheme provided by the embodiment of the present application, the video images played by the video playing device are based on different dynamic transformations of the watching user, and the video images played in the embodiment of the present application are more suitable for the behavior habits of the user, so that the difference and diversity of the video images to individuals are improved.
Referring to fig. 5, a flowchart of a video playback device according to another embodiment of the present application is shown, where the method may be applied to the video playback system shown in fig. 1, and the method may include the following steps:
step 501, a video playing device acquires a video image.
Step 502, the video playing device sends the video image to the mobile terminal.
Accordingly, the mobile terminal receives the video image from the video playing device.
For the description of step 501 to step 502, reference may be made to the above embodiments, which are not repeated herein.
In step 503, the video playback device obtains a picture quality processing instruction, where the picture quality processing instruction is used to instruct to process the picture quality of the video image based on the target processing mode.
In a possible implementation manner, a selection list of a processing manner set is displayed on the video playing device, and the processing manner set includes at least one processing manner. The user can select a target processing mode through touch, gestures, voice, a remote controller and the like, so that an image quality processing instruction is triggered to be sent to the video playing device. The target treatment modality may include at least one treatment modality.
In a possible implementation, the target processing means includes at least one of: an HDR (High Dynamic Range) processing mode, an MEMC (Motion estimation and Motion Compensation) processing mode, an SR (Super Resolution) processing mode, an NR (Noise Reduction) processing mode, a DCI (Dynamic Contrast enhancement) processing mode, an ACM (Auto Color Management) processing mode, and an LD (Local Dimming) mode.
The processing mode can process, repair and optimize the image signals and images in the signals, plays a vital role in the aspects of definition, color, contrast, smooth picture and the like, and effectively improves the picture quality expression.
HDR processing is a set of techniques used to achieve a greater dynamic range of exposure than common digital image techniques. The purpose of the HDR approach is to correctly represent the range luminance from sunlight directly to the darkest shadows in the real world, which can provide a greater range of dynamic range and image detail. And processing the video image based on the HDR processing mode to obtain the HDR video. HDR Video is encoded by 10bit HEVC (High Efficiency Video Coding), and the resolution is also 4K resolution. In a possible implementation manner, the video playing device is required to support HDR, and the video playing device can play HDR video.
The MEMC processing mode is a dynamic picture compensation technology, and the principle is to use a dynamic image system, and add a frame of motion compensation frame between two traditional frames of images, and increase the 50/60Hz refresh rate of the common flat-panel television to 100/120 Hz. By estimating the motion track of the object, the corresponding appearance of motion operation in the picture in the process is intelligently calculated according to the relation between the front picture and the rear picture, then the picture which is not in the video source is generated and inserted between the original frames, and therefore the picture is more smooth. Therefore, the moving picture is clearer and smoother and is better than the normal response effect, so that the effects of removing the residual image of the previous frame of image and improving the dynamic definition are achieved, and the trailing of the image is reduced to the degree that human eyes cannot perceive the image. The original 24 frames of video are processed into 60 frames or even 120 frames, so that the problems of picture jitter, ghosting, tailing and the like are avoided, and the picture looks clearer and smoother. The MEMC processing mode is a frame supplementing mode, a high frame rate can obtain more smooth and vivid animation, and the more the number of frames per second is, the smoother the displayed motion is.
