Fig. 2 is a flowchart illustrating an implementation of a video quality adjustment method according to an embodiment of the present application, which is applied to a client, where the client is a terminal device or an application installed on the terminal device. The specific implementation flow of the method is as follows:

s21: responding to a watching request of the target video, and sending the watching request to a server;

s22: receiving attribute information of the target video returned by the server, wherein the attribute information is determined after the server detects the video content of the target video;

wherein the viewing request of the target video may be triggered by the user. For example, a user triggers a viewing request by clicking a target video in a video presentation interface of a certain video APP (Application), and a client sends the viewing request of the target video to a server, where the server is a server corresponding to the video APP.

In the implementation of the application, the server can detect the video content of the target video through technologies such as image recognition and determine the attribute information of the target video.

Specifically, when the video content of the target video is detected by the image recognition technology, the content in the video image can be detected by preprocessing, feature extraction, classifier recognition and the like on the video image of one frame in the target video, and then the attribute information of the target video is determined according to the video content.

The attribute information of the target video includes, but is not limited to, part or all of the following:

video category information, video picture information.

In the embodiment of the present application, the video category information includes one or more of video size, type, year, country, and the like.

The following examples illustrate different video genre information:

wherein the video types include: movies, non-movies, and the like, and non-movies may be specifically classified as dramas, documentaries, music videos (music videos), and the like.

The video size includes: the video playing method comprises the steps of dividing a long video and a short video, wherein when the long video and the short video are divided, the video with the playing time less than 10 minutes can be divided into the short video, and the video with the playing time not less than 10 minutes is divided into the long video; or, according to the size of the video file, videos larger than 100MB (Mbyte, megabyte) are divided into long videos, videos smaller than 100MB in length are divided into short videos, and the like.

The video ages include: the 20 th century 60 s, the 20 th century 70 s, the 20 th century 80 s, the 20 th century 90 s, the 21 st century, and so on.

The video countries comprise domestic and foreign countries, wherein the foreign countries can be specifically subdivided into: country A, country B, country C; the Chinese can be further differentiated into inland dramas, harbor dramas, Taiwan dramas and the like.

In the embodiment of the present application, the video picture information includes one or more of video brightness, hue, contrast, sharpness, resolution, and the like.

The following illustrates different video picture information:

the video tones can be divided into dark tones and bright tones; the definition of the video can be classified into standard definition, high definition, super definition and the like; video brightness can be classified as dark, normal, bright, etc.; video contrast can be divided into: strong, normal, weak, etc.; video resolution can be divided into: 480P, 720P, 1080P, etc., where the letter P denotes progressive scan.

S23: and adjusting the image quality of the target video according to the attribute information.

Optionally, when the image quality of the target video is adjusted according to the attribute information, firstly, image quality parameters corresponding to the attribute information need to be determined according to a preset corresponding relationship between the image quality parameters and the attribute information; and further adjusting the image quality of the target video according to the determined image quality parameters.

The image quality parameters include, but are not limited to, the following parts or all:

definition, color, brightness, color temperature, sharpness, contrast, lens distortion, dispersion, resolution of the video picture.

Wherein, the definition of the video image refers to the definition of each detail shadow and its boundary on the video image; color refers to the color of the video picture; brightness refers to the brightness of the video picture; color temperature refers to the color temperature of the ambient light source; sharpness is an index reflecting the sharpness of the image plane and the sharpness of the image edges; contrast refers to the luminance under a white picture (brightest) divided by the luminance under a black picture (darkest); lens distortion is actually a generic term for the intrinsic perspective distortion of optical lenses, i.e. distortion due to perspective, which is very detrimental to the imaging quality of photographs; the dispersion degree refers to the degree of dispersion, and the phenomenon that the complex color light is decomposed into monochromatic light to form a spectrum is called light dispersion; regarding the resolution, the image projected by the projector is composed of many small projected points, the resolution represents the number of these points, and the higher the resolution, the sharper the projected image.

Taking the example that the attribute information of the target video includes the video type information, when the image quality of the target video is adjusted according to the video type information:

optionally, the video types are classified into movies and non-movies, and the pre-configured corresponding relationship between the image quality parameters and the attribute information is as follows: the set of image quality parameters corresponding to the movie type is image quality parameter 1, and the set of image quality parameters corresponding to the non-movie type is image quality parameter 2, wherein the set of image quality parameters includes definition, color, brightness, color temperature, and contrast, and the image quality parameters 1 and 2 include one or more of different definition, color, brightness, color temperature, and contrast. For example, the picture quality parameter 1 of the movie type is: definition a1, color b1, brightness c1, color temperature d1, contrast e1, and non-movie type image quality parameters 2 are: definition a2, color b1, brightness c1, color temperature d2, and contrast c 1. The two image quality parameters 1 and 2 are different in definition and color temperature of image quality, and the rest are the same.

If the attribute information of the target video 1 received by the client includes the video type in the video category information, and the specific video type is a movie, the image quality parameter corresponding to the target video 1 may be determined to be the image quality parameter 1 according to the correspondence relationship.

Taking the example that the attribute information of the target video includes video picture information (color tone), assuming that the color tone of the video picture can be divided into a cool color tone and a warm color tone, when the image quality of the target video is adjusted according to the video picture information:

the pre-configured corresponding relationship between the image quality parameters and the attribute information is as follows: the image parameters corresponding to the cool tone are image parameters 3, and the image parameters corresponding to the warm tone are image parameters 4, wherein the image parameters include definition, color, brightness, color temperature, and contrast. The image quality parameters 3 and 4 are different in one or more of sharpness, color, brightness, color temperature, and contrast of the image quality. For example, the image quality parameter 3 of the cool tone screen is: definition a3, color b3, brightness c3, color temperature d3, contrast e3, and image quality parameters 4 of the warm-tone picture are as follows: definition a3, color b4, brightness c4, color temperature d4, and contrast c 3. The two image quality parameters 3 and 4 are different in color, brightness, and color temperature of the image quality, and the rest are the same.

In the above embodiment, the image quality parameter matching the attribute information of the target video can be directly determined from the pre-configured image quality parameter according to the corresponding relationship between the attribute information and the image quality parameter, so that when the image quality of the target video is adjusted according to the determined image quality parameter, the adjusted image quality can be more matched with the video content of the target video, and the viewing experience of the user can be effectively improved. In addition, the image quality parameters are determined and the image quality is adjusted directly according to the corresponding relation between the pre-configured image quality parameters and the attribute information, manual setting by a user is not needed, and the efficiency of image quality adjustment is improved.

In another alternative embodiment, the pre-configured image quality parameter may be a default image quality parameter specified value given by a professional, and the professional pre-configures different image quality parameter specified values according to different attribute information.

In the embodiment of the present application, the requirements for the best image quality effect on different screen types are different considering that the same movie is in different film source formats. Optionally, the client may further obtain hardware information of the playing device when playing the target video, for example, whether the screen type of the playing device is LCD or OLED, whether the film source format is SDR or HDR, and the like. On the basis, the hardware information of the playing device can be further associated with the image quality parameters so as to improve the matching degree of the image quality of the target video and the current playing device, and further improve the adjustment effect of the image quality and the user experience.

In this embodiment, when determining the image quality parameter corresponding to the attribute information based on the pre-configured correspondence relationship between the image quality parameter and the attribute information, the specific procedure is as follows:

Table 1 shows a corresponding relationship between image quality parameters, attribute information, and hardware information according to an embodiment of the present application. Wherein the attribute information is a video type (movie or non-movie), and the hardware information includes a screen type and a film source format.

TABLE 1

As can be seen from table 1, when the video type is a movie and the film source format of the playback device is SDR, the video type corresponds to the image quality parameter a; when the video type is a movie and the film source format of the playing device is HDR, corresponding to the image quality parameter B; when the video type is non-movie and the film source format of the playing device is SDR, corresponding image quality parameters A'; when the video type is non-movie and the film source format of the playback device is HDR, the video quality parameter B' corresponds to.

Each of the image quality parameters shown in table 1 includes one or more of brightness, color, red gain, light sensing, motion stream, RGB sensor, and the like.

The red gain is a parameter for adjusting the color value of red in the picture color. Motion stream, also called double-speed driving, is a technique for optimizing the dynamic effect of lcd tv by motion estimation and frame interpolation. Wherein the double speed is generally referred to as double speed, i.e. the drive refresh frequency is raised from 50Hz to 100 Hz. In short, a technique of inserting a transition frame therein by judging the difference between the preceding and following images. The RGB sensor is a color sensor, and is a device for detecting colors by comparing colors of an object with reference colors that have been previously taught. And when the two colors are matched within a certain error range, outputting a detection result.

Optionally, the four sets of parameters are further divided into two sets of parameters [ OLED ] and [ LCD ] according to the screen type in the hardware information of the playback device in the image quality parameter a, the image quality parameter B, the image quality parameter a ', and the image quality parameter B'.

Assuming that the video type of the target video 1 is a movie and the hardware information includes LCD and SDR, the image quality parameters determined according to the corresponding relationship between the image quality parameters, the attribute information and the hardware information shown in table 1 are:

brightness: 10; color: 52; a light sensor: closing; moving flow: custom (minimum).

If the video type of the target video 2 is non-movie and the hardware information includes HDR and OLED, the determined image quality parameters are, according to the correspondence between the image quality parameters, the attribute information, and the hardware information shown in table 1:

brightness: 50; red gain: -4; a light sensor: turning to ash; moving flow: automatic; an RGB sensor: and off.

Optionally, when the attribute information includes video picture information, the same reasoning applies, and a corresponding relationship among the video picture information, the playback device hardware information, and the image quality parameter is configured in advance, and the corresponding image quality parameter is determined according to the pre-configured corresponding relationship. Or, the corresponding relationship among the video attribute information, the video picture information, the playing device hardware information and the image quality parameters is configured in advance, and when the image quality parameters are determined, the corresponding image quality parameters can be determined directly according to the corresponding relationship.

For example, when the video type is a movie, the video tone is a cool tone, and the film source format of the playback device is SDR, the video type corresponds to the image quality parameter C; when the video type is a movie, the video tone is a warm tone, and the film source format of the playback device is SDR, the corresponding image quality parameters D are not listed one by one.

It should be noted that the correspondence relationships between the pre-configured image quality parameters and the attribute information and the hardware information, which are listed in the above embodiments, are merely examples, and any correspondence relationship is applicable to the embodiments of the present application.

In the above embodiment, the corresponding relationship between the attribute information and the image quality parameter further takes into account the influence of the hardware information of the playback device on the image quality, and the image quality parameter determined according to the corresponding relationship between the image quality parameter and the attribute information and the hardware information is more specific, and the image quality effect adjusted according to the method is better.

Referring to fig. 3, a flowchart of another method for adjusting video quality according to an embodiment of the present disclosure is applied to a server, and the method includes the following steps:

s31: detecting the video content of the obtained target video, and determining the attribute information of the target video;

the method for obtaining the target video generally comprises the following steps: and acquiring the target video uploaded to the server by the user.

In the embodiment of the present application, an image recognition technology may be mainly used for detecting the video content of the target video.

Optionally, the attribute information of the target video may also be determined by the server after extracting the video tag of the target video.

The video tags of the target videos can be uploaded by the user when the target videos are uploaded, namely the user determines the corresponding video tags according to the video content of the target videos and uploads the video tags to the server.

For example, if the target video 3 is a movie type, the target video 4 is an entertainment type, the target video 5 is a documentary type, etc., the video type of the target video may be marked by a video _ type tag.

When the movie type is marked by the vio _ type tag, assuming that the movie type corresponds to the number 1, the vio _ type is 1; if the documentary type corresponds to the number 2, the vieo _ type is 2; assuming that the movie type corresponds to the number 3, the vieo _ type is 3.

When the server extracts the video tag and determines the attribute information according to the video tag, if the video tag extracted to the target video 4 has a video _ type field, it may be determined that the attribute information includes a video type, and if the video _ type is 2, it may be determined that the video type of the target video 4 is a documentary type.

In this way, the server can determine the attribute information of the video type directly according to the video _ type field, and the video content does not need to be detected, so that the method is simple and efficient. It should be noted that the video tag may also be used to mark other attribute information of the target video, such as color tone, brightness, and the like, and specific manners may be referred to in the above embodiments, and repeated details are not repeated.

In the embodiment of the application, if the target video uploaded by the user has no video tag, the server may detect the video content of the target video in an image recognition mode or the like, and further determine attribute information of the target video, such as a video type, a video color tone, and the like.

S32: and after receiving a watching request of the target video sent by the client, returning the attribute information of the target video to the client.

In the above embodiment, the server detects the video content to extract the attribute information of the video and send the attribute information to the client, and the client adjusts the image quality of the video according to the attribute information and plays the video. For each video, the attribute information of the video can be detected and determined, so that when the video quality is adjusted by the client, the video quality can be adaptively adjusted according to the video content, the adjusted video quality has better effect, and the matching degree of the video quality and the video content is improved. In addition, the viewing and feeling difference caused by the difference of different target video types can be effectively avoided, the operation that the user frequently modifies the setting of image quality parameters can be reduced, and the viewing and feeling experience of the user is greatly improved.

Fig. 4 shows an interaction timing chart of a video quality adjustment method according to an embodiment of the present application.

The specific implementation flow of the method is as follows:

step 401: an operator uploads a video to a server;

step 402: the server detects the video content of the video and determines the attribute information of the video according to the detection result;

step 403: a user selects a target video to watch;

step 404: the client side responds to a watching request triggered by a user, sends a watching request to the server and requests the video data of the target video;

step 405: the server returns the video data of the target video and the corresponding attribute information;

step 406: the client reads the hardware configuration of the television system, and the picture quality is set through the configurator according to the hardware configuration and the attribute information;

step 407: the client prompts the user that the image quality parameters are adjusted and then the adjusted image quality parameters are played.

In an optional implementation manner, the server may further obtain an environment control parameter corresponding to the target video, and convert the environment control parameter into an environment control instruction corresponding to a corresponding environment adjusting device, where the environment adjusting device has a binding relationship with the client; after receiving a viewing request of a target video sent by a client, the server returns video stream data of the target video and attribute information of the target video to the client, and also returns an environment control instruction to the client, so that the client controls corresponding environment adjusting equipment to adjust the viewing environment of the target video according to the control instruction.

Wherein the environmental attributes include, but are not limited to, some or all of the following:

temperature attribute, wind sound attribute, brightness attribute, position offset attribute.

In the embodiment of the application, the temperature attribute refers to the temperature of the environment when the user watches the film, and can be adjusted through environment adjusting equipment such as an air conditioner, a fan and the like; the wind sound attribute refers to wind sound in the environment when the user watches the film, and can be adjusted through environment adjusting equipment such as a fan and the like; the brightness attribute refers to the brightness in the environment when the user watches the film, and can be adjusted through environment adjusting equipment such as an electric lamp and the like; the position deviation attribute refers to a deviation of a viewing position of the user when the user views the target video, for example, the user deviates to a position closer to the playing device, deviates to a distance farther from the playing device, and the like, and can be adjusted by the environment adjusting device such as a sofa.

In this application embodiment, the environment adjusting device may be an internet of things device having a binding relationship with the client, and needs to access the internet of things, and the common environment adjusting device includes devices such as an electric lamp, an air conditioner, an air purifier, an intelligent sofa, and an electric curtain of an intelligent home.

In an optional implementation manner, when obtaining the environmental control parameter corresponding to the target video, the following two manners may be mainly used:

the method comprises the steps of obtaining a first obtaining mode, and obtaining preset environment control parameters corresponding to a target video.

In this way, the professional can perform professional configuration of the viewing environment on the target video to obtain the preset environment control parameters, and the professional uploads the preset environment control parameters to the server.

Taking the target video as a terrorist ice and snow killer as an example, the film can be generally viewed by setting darker light and lower temperature. If the brightness is measured by 100, the brightness of the lamp light corresponding to the film is set to be 30; if the normal temperature is 26 degrees, the temperature corresponding to the film can be set to be 2-3 degrees lower than the normal temperature, and the like.

In the above embodiment, after the professional makes a corresponding configuration suggestion of the environmental control parameter options for the existing environmental conditioning equipment, the server generates a corresponding environmental control instruction and issues the instruction to the client, so that the client can perform corresponding control on the existing environmental conditioning equipment.

And determining an environment control parameter matched with the video content of the target video according to the detection result of the video content of the target video.

In this way, the video content of the target video needs to be detected by the server, and the detection can be performed by technologies such as image recognition, and the like, and corresponding values of specific environmental attributes such as brightness change, rain, temperature change, visual offset and the like at each time point are recorded, and according to the environmental attributes and the corresponding values at each time point of the target video, the optimal environmental conditioning equipment is traversed, and converted into corresponding environmental control instructions.

For example, at a movie time point of 10 minutes and 6 seconds, the brightness changes, and the environmental control parameter corresponding to the brightness attribute is 10, which needs to be converted into an instruction for controlling the electric lamp. If the API (application programming Interface) corresponding to the defined brightness attribute is controlLight, the lighting control environment command can be obtained by conversion: controlLight (10).

For example, at a movie time point of 20 minutes and 6 seconds, the brightness changes again, and the environmental control parameter corresponding to the brightness attribute is 20, then the environmental control instruction for controlling lighting can be obtained by conversion: controlLight 20).

In the above embodiment, the final environmental control parameter is directly detected and determined based on the video content of the target video, so as to intelligently adjust the viewing environment of the user, and enable the viewing experience of the user to reach an optimal state.

In an optional implementation manner, if there are at least two environment adjusting devices for controlling the environment attribute corresponding to the same environment control parameter, the environment control parameter is converted into an environment control instruction corresponding to the corresponding environment adjusting device, which may be specifically divided into the following two manners:

and in the first conversion mode, selecting one environment adjusting device from at least two environment adjusting devices, and converting the environment control parameters into the environment control instruction corresponding to the selected environment adjusting device.

For example, if the environmental control parameter is wind sound 20, the corresponding environmental attribute is wind sound attribute, and the environmental adjustment device for controlling the wind sound attribute has an air conditioner and an electric fan, one environmental adjustment device may be selected from the air conditioner and the electric fan, and if the selected environmental adjustment device is the electric fan, the environmental adjustment device is converted into an environmental control instruction for controlling the electric fan: control FanWind (20).

If the selected environment adjusting equipment is an air conditioner, converting the selected environment adjusting equipment into an environment control instruction for controlling the air conditioner: control controlcontrollerWind (20).

And a second conversion mode, namely converting the environment control parameters into environment control instructions corresponding to the environment adjusting devices respectively aiming at the environment adjusting devices, and setting priorities for the environment control instructions.

In the mode, an environment control instruction controlcontrolcontrolcontrollerWind (20) can be obtained by converting the air conditioner; an environmental control command, controlFanWind (20), is available for the electric fan.

Wherein, when setting priority to the two environment control instructions, the priority can be determined according to the primary and secondary environment attributes of the corresponding environment adjusting device.

Taking the air conditioner as an example, the environment attribute that the air conditioner corresponds includes temperature, wind sound etc. and wherein main environment attribute is the temperature, divide into 3 gears: cold, normal temperature, hot; the secondary environment attribute is wind sound, and the integer value gear is generally 3: no wind, little wind, strong wind. Among them, the air conditioner is mainly used for controlling temperature because the wind sound effect produced by the air conditioner is not good as that of a fan. Taking an electric fan as an example, the corresponding main environmental attribute is wind noise, for example, an integer number gear is generally 3: no wind, little wind, strong wind.

Therefore, when the two environmental control commands are prioritized, the priority of the environmental control command corresponding to the electric fan can be set higher than the priority of the environmental control command corresponding to the air conditioner. In addition, the environmental control parameters can be converted into commands according to the priority definition, namely, the environmental control parameters are converted into commands controlFanWind (20) for controlling the fan, and then converted into commands controlControllerWind (20) for controlling the air conditioner.

Optionally, when there are at least two environment adjusting devices for controlling the environment attributes corresponding to the same environment control parameter, the environment adjusting devices may also be the same type of environment adjusting devices, for example, there are two air conditioners, and at this time, when determining the priorities of the two air conditioners, the priorities may be determined according to actual conditions, for example, according to the powers, locations, and the like of the air conditioners.

In the above embodiment, a manner of generating the environment control instruction when there are many environment adjusting devices for controlling the same environment attribute is provided, and the environment control parameter is converted into at least one environment control instruction by a priority or a selection manner, so that the generation efficiency or the use efficiency of the environment control instruction is improved.

In an optional implementation manner, after the client sends the viewing request to the server, the client should also receive video stream data of the target video returned by the server; after the image quality of the target video is adjusted according to the attribute information, the video stream data can be decoded, and the target video can be played through the adjusted image quality.

In the above embodiment, the target video is directly played through the adjusted image quality after the image quality is adjusted, which is helpful for improving the viewing experience of the user.

In an optional implementation manner, after the client sends the viewing request to the server, if an environment control instruction returned by the server is received, the corresponding environment adjusting device is controlled according to the environment control instruction, so as to adjust the viewing environment of the viewing target video.

The environment adjusting equipment is specifically bound with the client; the environment control instruction is obtained by converting an environment control parameter corresponding to the target video by the server, and the specific implementation manner may be referred to in the above embodiments.

In the embodiment of the application, after receiving the environment control instruction, the client controls the corresponding environment adjusting device according to the received environment control instruction.

For example, if the environment control command received by the client is control fanwind (20), the fan is controlled to adjust the rotating speed, and the wind noise is adjusted to 20; and if the environment control command received by the client is control light (10), controlling the electric lamp to adjust the light brightness to 10.

In the above embodiment, the client adjusts the film viewing environment of the target video based on the environment control instruction, so that the indoor environment achieves the best film viewing experience, and the user experience is improved.

In an alternative embodiment, if there are at least two environment control commands for controlling the same environment attribute; when the corresponding environment adjusting device is controlled according to the environment control instruction, the corresponding environment adjusting device needs to be controlled according to the priority of at least two environment control instructions.

For example, the client receives two environment control instructions for controlling the wind sound property, which are: the air conditioner control method comprises a control FanWind (20) and a control controlControlWind (20), wherein the priority of the control FanWind (20) is higher than that of the control controlControlWind (20), namely the control FanWind (20) is a first instruction, and the control ControlControlWind (20) is a second instruction, when a client controls an environment adjusting device according to the two environment control instructions, an electric fan is controlled according to the first instruction, and if the environment adjusting device bound with the client under the current environment does not have the electric fan, or the electric fan is controlled according to the first instruction and fails, the air conditioner is controlled according to the second instruction.

In the above embodiment, a manner is provided in which the environment adjustment device is controlled according to the priority when the client receives a plurality of environment control instructions for controlling the same environment attribute, and the environment adjustment device can be effectively controlled on the premise of ensuring the viewing environment adjustment.

Optionally, a corresponding adjustment time may be further set in the environment control instruction, where the adjustment time is used to indicate a time at which the client controls the environment adjustment device.

For example, the client receives two environment control instructions for adjusting the brightness, wherein the adjusting time of the controlLight (10) is 10 minutes and 6 seconds after the target video is played, the client controls the electric lamp to adjust the brightness of the lamp light to 10 at the time of 10 minutes and 6 seconds; when the adjusting time of the control light (20) is 20 minutes and 6 seconds after the target video is played, the client controls the electric lamp to adjust the brightness of the light to 20 at the time of 20 minutes and 6 seconds.

In the embodiment, the film watching environment is adjusted by fully referring to the video content of the target video, and the user experience is improved.

Optionally, after receiving the environment control instruction, the client may further prompt the user to determine whether to perform the corresponding environment adjustment before controlling the corresponding environment adjustment device according to the environment control instruction, and execute the corresponding environment control instruction according to the selection of the user.

For example, when the target video is played for 10 minutes and 6 seconds, prompting the user whether to adjust the brightness of the electric lamp to 10, and if the user agrees, controlling the electric lamp to adjust the light; and if the user does not agree, the electric lamp is not controlled to adjust the light.

In the embodiment, the film viewing environment is adjusted according to the subjective consciousness of the user, so that the adjusted light source environment meets the user's experience, and the film viewing experience of the user is improved.

Referring to fig. 5, a schematic view of a viewing environment adjusting module provided in an embodiment of the present application is shown, where the viewing adjusting module is mainly used for a server to generate an environment control instruction corresponding to a target video, and specifically includes the following four parts:

1) and the environment adjusting equipment mark attribute defining module.

The model needs manual operation, environment attributes which can be matched with various environment adjusting devices are manually led in, some environment adjusting devices have multiple environment attributes, the environment adjusting devices can be marked as primary environment attributes and secondary environment attributes according to specific effects, and values of the environment attributes are defined, the definition is generally divided into 2-3 gears, each gear is a section, and electricity consumption caused by continuous control of the environment adjusting devices is avoided.

For example, the environment attribute corresponding to the electric lamp is brightness, and the brightness is 3 steps: dark, normal, bright; the corresponding attribute of the air conditioner is the main environmental attribute temperature, and is divided into 3 gears: cold, normal temperature, hot, secondary environment attribute wind sound, the integer numerical value gear is generally 3 grades: no wind, little wind, strong wind; the main environmental attribute that water spray fan corresponds is the wind sound, and integer numerical value gear is 3 grades generally: the raining effect can be controlled according to the switch variable of the water spray fan, and the switch variable comprises opening or closing; the main environmental attribute that intelligence sofa corresponds is offset, offset when watching the shadow through adjustment intelligence sofa offset control, and the position variable is: up, down, left, right, etc.

It should be noted that, as the environment adjusting devices increase more extractable environment attributes, the viewing experience becomes richer and richer.

2) And an environment attribute extraction module.

The module is mainly used for recording the corresponding numerical values of specific attributes of each time point of the target video, such as brightness change, rainfall, temperature change, visual offset and the like, through a video identification technology.

3) And the environment attribute and environment control instruction matching module.

The module is mainly used for traversing the optimal environment adjusting equipment through the attribute and the corresponding value of each time point of the target video obtained in the previous link, and converting the attribute into a corresponding environment control instruction, for example, at a movie time point 10.06, the brightness attribute (10) needs to be changed into the instruction controlLight (10) for controlling the electric lamp.

4) And the environment control instruction and video integration module.

The module is mainly used for integrating the time point of the environment control instruction with the video playing time point, so that when a user requests video data, the environment control instruction can be requested together, the environment control instruction and video stream data of a target video are issued to a client side together, and the client side controls the environment adjusting equipment to adjust the viewing environment according to the environment control instruction while playing the target video.
