[0031] The present disclosure will be further described in detail below in conjunction with the accompanying drawings and examples. It should be understood that the examples provided herein are merely for explaining the present disclosure and are not intended to limit the present disclosure. In addition, the examples provided below are partial examples for implementing the present disclosure, rather than providing all examples for implementing the present disclosure. In the absence of conflict, the technical solutions described in the examples of the present disclosure may be implemented in any combination.

[0032] It should be noted that, in the embodiments of the present disclosure, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a method or apparatus comprising a series of elements includes not only the elements explicitly stated, but also other elements not explicitly listed, or also includes elements inherent to the implementation of the method or apparatus. In the absence of further restrictions, an element defined by the sentence "comprising a ..." does not exclude the presence of other related elements (such as steps in the method or units in the apparatus, for example, a unit may be part of a circuit, part of a processor, part of a program or software, etc.) in the method or apparatus comprising the element.

[0033] For example, the video data transmission method provided by the embodiment of the present disclosure includes a series of steps, but the video data transmission method provided by the embodiment of the present disclosure is not limited to the recorded steps. Similarly, the video data transmission device provided by the embodiment of the present disclosure includes a series of units, but the device provided by the embodiment of the present disclosure is not limited to including the units explicitly recorded, and can also include units that need to be set up to obtain relevant information or perform processing based on information.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which the present disclosure pertains. The terms used herein are for the purpose of describing specific embodiments only and are not intended to limit the present disclosure.

[0035] It is understandable that in the specific implementation of this application, relevant data is involved. When the embodiments in this application are applied to specific products or technologies, user permission or consent is required, and the collection, use and processing of relevant data must comply with relevant laws, regulations and standards of relevant countries and regions.

[0036] Figure 1 The flowchart of the video data transmission method according to one embodiment of the present application is schematically shown. The execution subject of the video data transmission method can be any device with video playback capability, such as a TV, computer, mobile phone, smart watch, and home appliance.

[0037] like Figure 1As shown, the video data transmission method may include steps S110 to S140.

[0038] Step S110, during the video playback via the network, detecting whether playback freeze occurs through the network module;

[0039] Step S120: If yes, compress the video frame to be transmitted to obtain compressed video data;

[0040] Step S130, generating a bandwidth allocation amount according to the data packet size of the compressed video data;

[0041] Step S140: adjusting the bandwidth allocated to the multimedia module according to the bandwidth allocation amount through the network module, so that the multimedia module transmits the compressed video data based on the allocated bandwidth.

[0042] When playing a video over the network, the device receives video data from the network through the network module and transmits the video frames in the video data to the multimedia module, which then transmits the frames to the playback module for playback. In the embodiment of the present application, the network module provides a video playback detection function. During the process of playing a video over the network, the network module detects whether there is any playback freeze in the playback module.

[0043] After detecting playback freezes, the network module compresses the "untransmitted video frames" in the video data received by the network module that have not yet been transmitted to the multimedia module to generate compressed video data. Each compressed untransmitted video frame may include one or more video frames. Based on the packet size of the compressed video data, the bandwidth allocation corresponding to the packet size is further determined.

[0044] Furthermore, the network module adjusts the bandwidth allocated to the multimedia module according to the bandwidth allocation amount, so that the multimedia module transmits the compressed video data to the playback module based on the allocated bandwidth, thereby reliably avoiding the multimedia module from being unable to send video frame data to the playback module in a timely manner due to the small bandwidth, and reliably avoiding video playback freezes.

[0045] In this manner according to the embodiments of the present application, during the process of playing a video over the network, the network module detects playback freezes in real time and when playback freezes are detected, the video frames to be transmitted are compressed, and the bandwidth allocation amount is generated in reverse based on the data packet size of the compressed video data. The network module further adjusts the bandwidth allocated to the multimedia module based on the bandwidth allocation amount, so that the multimedia module can reliably transmit the compressed video data based on the allocated bandwidth, thereby effectively improving the smoothness of video playback and enhancing the user experience.

[0046] Described below Figure 1 When video data is transmitted under the embodiment, further optional specific embodiments are provided for each step performed.

[0047] In one embodiment, see Figure 2 The method of compressing the video frame to be transmitted to obtain compressed video data includes: step S210, obtaining network status data; step S220, compressing the video frame to be transmitted according to the network status data to obtain compressed video data.

[0048] The network status data may include but is not limited to available bandwidth, throughput, signal strength, etc. The network module compresses the video frames to be transmitted according to the network status data, which can further ensure the transmission effect of the compressed video data.

[0049] It can be understood that in other optional embodiments, compressing the video frames to be transmitted to obtain compressed video data includes: compressing the video frames to be transmitted according to a predetermined compression method to obtain compressed video data.

[0050] In one embodiment, see Figure 3 , compressing the video frame to be transmitted according to the network status data to obtain compressed video data, including: step S310, performing status rating according to the network status data to obtain a network status level; step S320, determining a compression size according to the network status level; step S330, compressing the video frame to be transmitted according to the compression size to obtain the compressed video data.

[0051] According to the network status data, a status rating can be performed to obtain the current network status level. The higher the network status level, the better the network condition. The compression size is determined according to the network status level, and the video frame to be transmitted is compressed according to the compression size, that is, the compressed video data can be reliably obtained according to different network conditions.

[0052] In one embodiment, determining the compression size according to the network status level includes one of the following methods:

[0053] First, determining a predetermined size corresponding to the network status level as the compressed size;

[0054] The second method is to calculate a compression level according to a user rating of a video viewing user and the network status level, and determine the compression size according to the compression level.

[0055] In the first manner, corresponding predetermined sizes are set for different network status levels. The network module can determine the corresponding predetermined size according to the current network status level, and determine the predetermined size corresponding to the network status level as the compressed size.

[0056] In the second method, user ratings of video viewing users are further introduced. The network module calculates the compression level based on the user ratings of video viewing users and the network status level, and determines the compression size based on the compression level. Compression processing based on the compression size can further take user conditions into consideration and further ensure the user experience when transmitting based on compressed video data.

[0057] In one embodiment, the user rating of the video viewing user can be obtained in the following manner: obtaining the user characteristics, video preferences and video types of the video viewing user played through the network; analyzing according to the user characteristics, the video preferences and the video types to obtain the user rating; and transmitting the user rating to the network module.

[0058] In this embodiment, the device can pre-collect and record user characteristics and video preferences of video viewers. User characteristics may include, but are not limited to, age and vision data, and video preferences refer to the types of videos preferred by the user. The device can also obtain the type of the video currently being played over the network in real time.

[0059] The device analyzes the user characteristics, the video preferences and the video type to obtain the user rating, and transmits the user rating to the network module. The network module can then calculate the compression level based on the user rating and the network status level.

[0060] In one embodiment, the analysis based on the user characteristics, the video preferences and the video type to obtain the user rating may include: determining a deviation score based on the video preferences and the video type; determining a feature score based on the user characteristics; calculating based on the deviation score and the feature score to obtain a user score; and determining the user rating based on the user score.

[0061] Video preference refers to the video type preferred by the user. Based on the video preference and the video type, a deviation score between the video preference and the video type can be determined from a predetermined deviation table. The higher the deviation score, the greater the difference between the video preference and the video type.

[0062] User features may include but are not limited to sub-features such as age and vision data. The sub-feature scores of sub-features such as age and vision data may be queried from a preset feature score table, and the sub-feature scores of all sub-features may be summed to obtain the feature score of the user feature.

[0063] The user score is calculated based on the deviation score and the feature score according to a predetermined formula. For example, the deviation score and the feature score are summed to obtain the user score. Then, the user rating corresponding to the user score can be determined from the preset rating table.

[0064] In one embodiment, the compression level is calculated based on the user rating and the network status level, including one of the following methods:

[0065] The first method is to perform weighted summation of the user rating and the network status level according to a predetermined weighting coefficient to obtain the compression level;

[0066] The second method is to determine a dynamic weighting coefficient that matches the viewing status of the video viewing user, and perform weighted summation on the user rating and the network status level according to the dynamic weighting coefficient to obtain the compression level.

[0067] In the first manner, a fixed predetermined weighting coefficient is predetermined in advance, and then the user rating and the network status level are weighted and summed according to the predetermined weighting coefficient to obtain the compression level.

[0068] In the second approach, the device can first determine the viewing state of the video viewer, which can be an emotional state obtained through facial emotion recognition. It then determines a dynamic weighting coefficient that matches the video viewer's viewing state from a coefficient table. The coefficient table specifies dynamic weighting coefficients corresponding to different viewing states. The user rating and network status level are then weighted and summed according to the dynamic weighting coefficients to obtain the compression level. Based on this compression level, the compression size is determined for compression, further enhancing the user's viewing experience.
