[0023] The following description of exemplary embodiments of the present disclosure is made in conjunction with the accompanying drawings, including various details of the embodiments of the present disclosure to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be appreciated by those skilled in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope of the present disclosure. Similarly, for the sake of clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.

[0024] In this disclosure, unless otherwise specified, the use of terms such as "first" and "second" to describe various elements is not intended to limit the positional relationship, temporal relationship, or importance relationship of these elements. Such terms are only used to distinguish one element from another.

[0025] The terms used in the descriptions of the various examples described in this disclosure are for the purpose of describing specific examples only and are not intended to be limiting. Unless the context clearly indicates otherwise, if the number of elements is not specifically limited, the element may be one or more. In addition, the term "and / or" used in this disclosure encompasses any one and all possible combinations of the listed items.

[0026] With innovations in content production, the use of AI (artificial intelligence) to automatically generate videos from images and text has become commonplace, significantly enhancing the user experience of text-based content. However, the quality of videos produced using AI often varies greatly, requiring video platforms to assess their quality and screen out substandard videos to ensure the quality of the videos they publish.

[0027] In related technologies, in order to evaluate the quality of videos and filter out unqualified videos, the time period range corresponding to each quality evaluation dimension (or indicator item) is often manually marked offline and the output report is manually calculated. Specifically, this method requires manual playback of the video to be evaluated in a browser, recording the time period occupied by the score of each indicator item, and then manually calculating the proportion of the total time period with the same score under the same indicator item to the total length of the video, determining the evaluation results based on the scores and proportions, and finally manually filling in the form. However, this method is inefficient, time-consuming and labor-intensive, and cannot control the progress of the evaluation. There is no online data result, which is not conducive to data tracing and the rapid output of evaluation results. Therefore, there is an urgent need for a method that can evaluate the quality of videos efficiently and at low cost.

[0028] In response to the above technical problems, according to one aspect of the present disclosure, a video quality assessment method is provided.

[0029] The embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0043] Figure 1 The system 100 may be configured and operated in various ways to enable application of the various methods and apparatuses described in accordance with the present disclosure.

[0044] The video quality assessment method according to an embodiment of the present disclosure is described in detail below.

[0045] Figure 2 FIG. 2 shows a flow chart of a video quality assessment method 200 according to an embodiment of the present disclosure. Figure 2 As shown, method 200 includes steps S201 , S202 and S203 .

[0046] In step S201, quality assessment data of a video including a plurality of video segments is obtained. The quality assessment data includes a score on at least one quality assessment dimension.

[0047] In an example, the quality assessment data may be stored in a DB (Data Base) or a Remote Dictionary Server (Redis).

[0048] In the example, the quality assessment dimension can be a standard and angle for evaluating video quality, and the level of the video in various quality assessment dimensions can be directly related to the perception of the video to the user. The quality assessment dimension can be related to the quality of the video's picture or sound, for example, it can include quality assessment dimensions such as background sound, noise, freeze, picture correlation, picture jitter, and picture accuracy. The quality assessment dimension can be divided into multiple levels of quality assessment dimensions. For example, the first-level quality assessment dimension can include a quality assessment dimension related to the picture and a quality assessment dimension related to the sound, etc. Each first-level quality assessment dimension can be divided into multiple second-level quality assessment dimensions. For example, the above-mentioned background sound and noise can be second-level quality assessment dimensions under the first-level quality assessment dimension related to the sound, and the above-mentioned freeze, picture correlation, picture jitter, and picture accuracy can be second-level quality assessment dimensions under the first-level quality assessment dimension related to the picture.

[0049] In the example, a set of quality assessment dimensions can be pre-set, which may include, for example, quality assessment dimensions such as background sound, noise, freeze, picture correlation, picture jitter, and picture accuracy. When evaluating the quality of a video, the quality assessment data of the video may correspond to one or more quality assessment dimensions in the set of quality assessment dimensions. For different videos, the quality assessment may be performed from different quality assessment dimensions in the set of quality assessment dimensions. Therefore, by obtaining the quality assessment data of the video, it is possible to determine which quality assessment dimension or dimensions in the set of quality assessment dimensions have a score for the video segment, so as to determine from which quality assessment dimension or dimensions the video is quality assessed.

[0050] In the example, the score range on the quality assessment dimension can be pre-set. For example, the quality assessment dimension can be pre-set to have four score values: 0, 1, 2, and 3. These four score values ​​can represent the quality of the video segment on the quality assessment dimension. For example, 0 points can indicate that the quality of the video segment on the quality assessment dimension is very low, 1 point can indicate that the quality of the video segment on the quality assessment dimension is relatively low, 2 points can indicate that the quality of the video segment on the quality assessment dimension is relatively high, and 3 points can indicate that the quality of the video segment on the quality assessment dimension is very high. A score value of "all" can also be set for the quality assessment dimension to indicate that the quality assessment of the video involves this quality assessment dimension, but the video reviewer has not assigned a score to the video on this quality assessment dimension.

[0051] In the example, the score of the video segment on the quality assessment dimension can be a score given by a video reviewer through subjective judgment. The video reviewer can use Figure 1 The clients 101 , 102 , 103 , 104 , 105 and / or 106 shown for video review upload scores of video segments on quality assessment dimensions and other quality assessment data to the server 120 .

[0052] In step S202 , for each quality assessment dimension, a score of at least one video segment evaluated on the quality assessment dimension among the plurality of video segments is determined.

[0053] In an example, the score of a video segment on a quality assessment dimension may be related to a predetermined judgment condition. The predetermined judgment condition may indicate whether the video segment is greater than, greater than or equal to, less than, or less than or equal to a predetermined threshold under a quality assessment indicator. The quality assessment indicator may include, for example, the number of occurrences, duration, and duration ratio of quality issues.

[0054] Since the score of a video segment on a quality assessment dimension can be a subjective score determined by a video reviewer, it may not accurately indicate the quality of the video segment. However, after determining whether the video segment meets the predetermined criteria based on a standard judgment basis, it can be determined whether the score corresponding to the predetermined criteria applies to the video segment, and this score can be used as the final score for the quality assessment dimension. This final score can then more accurately indicate the quality of the video segment.

[0055] In the example, the predetermined judgment condition corresponding to the score of the video segment in the quality assessment dimension may involve multiple quality assessment indicators. In this case, the multiple quality assessment indicators may have a predetermined logical operation relationship to constitute the predetermined judgment condition.

[0056] In step S203, a quality assessment result of the video is determined based on one or more video segments having a predetermined same score in the at least one video segment.

[0057] In an example, the quality assessment result of a video may include a final score on one or more quality assessment dimensions, and the score range of the final score may also be pre-set. For example, the final score of the video on each quality assessment dimension may be pre-set to have four score values: 0, 1, 2, and 3. These four score values ​​may represent the quality of the quality assessment result of the video on that quality assessment dimension. For example, a score of 0 may indicate that the quality of the video on that quality assessment dimension is very low, a score of 1 may indicate that the quality of the video on that quality assessment dimension is relatively low, a score of 2 may indicate that the quality of the video on that quality assessment dimension is relatively high, and a score of 3 may indicate that the quality of the video on that quality assessment dimension is very high.

[0058] According to the video quality assessment method of the embodiment of the present disclosure, the quality assessment result of the video is determined by determining the respective scores of at least one video segment evaluated on each quality assessment dimension among multiple video segments based on the quality assessment data uploaded by the video reviewer. The final score of the video on each quality assessment dimension can be automatically calculated according to predetermined rules or judgment conditions. Compared with manual statistics of video quality scores, the efficiency is greatly improved, and the accuracy of data calculation is also guaranteed, making the video quality assessment result more accurate and reliable.

[0059] Various aspects of the video quality assessment method according to embodiments of the present disclosure are further described below.

[0060] According to some embodiments, each quality assessment dimension may include at least one quality assessment indicator, where the at least one quality assessment indicator includes at least one of the number of times, duration, and duration ratio. Step S203 of the video quality assessment method 200 may include: determining a quality assessment result of the video based on whether the at least one quality assessment indicator satisfies a predetermined judgment condition for one or more video segments having the same predetermined score.

[0061] Figure 3 A schematic diagram illustrating setting judgment conditions according to an embodiment of the present disclosure is shown.

[0062] like Figure 3 As shown, the quality of the video segment can be evaluated based on the quality evaluation dimension of "broadcast accuracy" to determine whether to assign "0 points" to the video. The quality evaluation dimension can also be called a labeling item.

[0063] In the example, the final score of the video on the quality assessment dimension of "broadcast accuracy" can be related to a predetermined judgment condition. Specifically, the user sets the predetermined judgment condition for the video on the quality assessment dimension of "broadcast accuracy" to include a score of "0", a type (i.e., quality assessment index) of "number of times", a condition of ">=", and a threshold of "5". Therefore, the predetermined judgment condition for the video to obtain a final score of "0" on the quality assessment dimension of "broadcast accuracy" is: the number of video segments that obtain a score of "0" on the quality assessment dimension of "broadcast accuracy" is greater than or equal to 5. In other words, it can be determined whether the video segments that are subjectively judged as "0" on the quality assessment dimension of "broadcast accuracy" by the video reviewers in the video have accumulated five or more occurrences. If so, the final score of the video on the quality assessment dimension of "broadcast accuracy" can be determined to be 0 points.

[0064] It is understandable that Figure 3This is just an example. Depending on the actual application, the "Score" column in the predetermined judgment condition content can also be checked as "1", "2", "3", or "all", the "Type" column can also be checked as "Duration" or "Duration Percentage", the "Condition" column can also be checked as ">", "<", or "<=", and the "Threshold" column can be entered with other custom values ​​to set different predetermined judgment conditions.

[0065] According to an embodiment of the present disclosure, by automatically calculating the final score of the video in each quality assessment dimension based on predetermined judgment conditions, the video quality assessment result can have higher accuracy and reliability compared to manual subjective scoring.

[0066] According to some embodiments, in response to each quality assessment dimension including at least two quality assessment indicators, a predetermined logical operation relationship may exist between the at least two quality assessment indicators to constitute a predetermined judgment condition.

[0067] Figure 4 A schematic diagram of setting judgment conditions according to another embodiment of the present disclosure is shown.

[0068] like Figure 4 As shown, the quality of the video segment can be evaluated based on the quality evaluation dimension of "picture relevance" to determine whether to assign a "0 score" to the video.

[0069] In the example, the final score of the video in the quality assessment dimension of "picture relevance" can be related to a predetermined judgment condition. Specifically, the user sets the predetermined judgment condition for the video in the quality assessment dimension of "picture relevance" to include two strategies. One of the strategies includes a score of "0", a type (i.e., quality assessment indicator) of "duration" (or duration), a condition of ">=", and a threshold of "30". The other strategy includes a score of "0", a type (i.e., quality assessment indicator) of "duration ratio", a condition of ">=", and a threshold of "0.2". The connection relationship between the two strategies (i.e., the predetermined logical operation relationship) is set to "||" (i.e., logical OR). Therefore, the predetermined judgment condition for the video to obtain a final score of "0" in the quality assessment dimension of "picture relevance" is: the cumulative duration of the video segments that obtain a score of "0" in the quality assessment dimension of "picture relevance" is greater than or equal to 30, or the cumulative duration of the video segments that obtain a score of "0" in the quality assessment dimension of "picture relevance" accounts for a proportion of the entire video duration that is greater than or equal to 0.2.

[0070] That is to say, it can be determined whether the cumulative duration of video segments that are subjectively judged as "0" by video reviewers in the quality assessment dimension of "broadcast accuracy" reaches 30 seconds or more, and whether the cumulative duration reaches 20% or more of the total duration of the entire video. If one or both of the following conditions are met: the cumulative duration of video segments that are subjectively judged as "0" by video reviewers in the quality assessment dimension of "broadcast accuracy" reaches 30 seconds or more, and the cumulative duration reaches 20% or more of the total duration of the entire video, then the final score of the video in the quality assessment dimension of "picture relevance" can be determined to be 0 points.

[0071] It is understandable that Figure 4 This is just an example. Depending on the actual application, the predetermined judgment condition may include more strategies, for example, 4 or 5. In the content of these strategies, the "Score" column can be checked as "0", "1", "2", "3" or "all", the "Type" column can be checked as "Number of times", "Duration" or "Percentage of duration", the "Condition" column can be checked as ">="", ">", "<" or "<=", the "Threshold" column can be used to enter various customized values, and the "Continuation" column can be checked as "||" (logical OR) or "&&" (logical AND) to set different predetermined judgment conditions.

[0072] In the example, the logical operation relationship checked in the "Continuation" column can indicate that the logical operation is performed on the result of the logical operation of the strategy and all previous strategies. When there is only one previous strategy, it means that the logical operation is performed on the previous strategy. When there is only one strategy under the quality assessment dimension, such as Figure 3 As shown, there is no need to predetermine the logical operation relationship.

[0073] According to an embodiment of the present disclosure, by connecting at least two quality assessment indicators with a predetermined logical operation relationship to form a predetermined judgment condition, the video can be scored in each quality assessment dimension from multiple angles at the same time, thereby further improving the reliability of the video quality assessment results.

[0074] According to some embodiments, in the quality assessment data, for each quality assessment dimension, a mapping relationship between a score on the quality assessment dimension and one or more video segments corresponding to the score may be stored. Figure 2 Step S202 of the video quality assessment method 200 may include: finding one or more video segments corresponding to the scores according to the scores on the quality assessment dimension based on the mapping relationship; and determining the scores of the one or more video segments.

[0075] In the example, since information related to the mapping relationship between scores on quality assessment dimensions and one or more video segments corresponding to the scores may be frequently read and written, such information can be cached using Redis's hash structure to support users in adding quality assessment data for video segments for multiple quality assessment dimensions at different time points.

[0076] In the hash structure, a constant + user email prefix + video ID (Identity document) can be used as the key, and the value of the time point can be used as the field. JSON characters can be used to store the start and end time points of each video segment and the duration of the video segment, and the current JSON characters can be used as the value of the hash structure.

[0077] In the example, other quality assessment data that does not need to be read and written frequently can be stored in the DB to ensure the stability of the quality assessment data.

[0078] In the example, you can first concatenate the keys of the hash structure corresponding to a certain user (for example, a video reviewer) and the video he or she evaluates, and query the values ​​of all hash structures corresponding to this key. Then you can traverse the json characters corresponding to the values ​​of different domains in the hash structure and convert the data type into an array. In this process, outliers can be eliminated. For example, outliers can be data where the start time of the video segment is less than 0, the end time of the video segment is greater than the total length of the video, or the end time of the video segment is less than the start time of the video segment. Next, a new array can be constructed for the quality assessment dimension. The new array can be used to store the mapping relationship between the score on the quality assessment dimension and one or more video segments corresponding to the score.

[0079] Figure 5 A schematic diagram of a storage mapping relationship according to an embodiment of the present disclosure is shown.

[0080] In this example, array 500 stores information at three levels, including a first level of quality assessment dimensions, a second level of score values ​​under a single quality assessment dimension, and a third level of video segments assigned the score values ​​under the single quality assessment dimension.

[0081] At the first level, array 500 may include quality assessment dimension 511, quality assessment dimension 512, quality assessment dimension 513 and multiple other quality assessment dimensions not shown. These quality assessment dimensions may be, for example, background sound, noise, broadcast accuracy, freeze, picture correlation, picture jitter, picture accuracy and other quality assessment dimensions.

[0082] Each quality assessment dimension may have multiple second-level score values. Taking quality assessment dimension 511 as an example, quality assessment dimension 511 may correspond to score value 521 (e.g., 0), score value 522 (e.g., 1), score value 523 (e.g., 2), and multiple other score values ​​not shown. In some embodiments, each quality assessment dimension may correspond to four different score values, such as 0, 1, 2, and 3.

[0083] Corresponding to each score value of each quality assessment dimension, there may be a corresponding video segment, and the information of these video segments may constitute the third level of array 500. In some embodiments, one or some score values ​​of some quality assessment dimensions may not have a corresponding video segment. Taking the score value 521 of the quality assessment dimension 511 as an example, the video segments with a score value 521 in the quality assessment dimension 511 may include video segment 531 (for example, 00:01-00:03 of the video), video segment 532 (for example, 00:05-00:10 of the video), video segment 533 (for example, 00:18-00:19 of the video), and multiple other video segments not shown.

[0084] In the example, by traversing array 500 and aggregating the data, the aggregated evaluation information of the video on a certain quality assessment dimension can be obtained, such as "[Quality Assessment Dimension 511] 00:01-00:03 (for example, it can correspond to video segment 531), 00:05-00:10 (for example, it can correspond to video segment 532), 00:18-00:19 (for example, it can correspond to video segment 533), a total of 8 seconds, accounting for 5%."

[0085] According to the embodiment of the present disclosure, by storing the quality assessment data of the video in a mapping relationship between the score on the quality assessment dimension and the video segment corresponding to the score, it is possible to facilitate the determination of the aggregated assessment information of the video on each quality assessment dimension, such as the total number of times the quality problem corresponding to the quality assessment dimension appears in the entire video, the cumulative duration, and the proportion of the cumulative duration in the entire video duration. At the same time, the quality assessment data of the video stored in this way can also facilitate video reviewers to control the progress of video quality assessment and trace quality assessment data. When it is necessary to add, modify or delete video segment information, the quality assessment data can be updated efficiently.

[0086] Figure 6 FIG. 6 is a flow chart of a video quality assessment method 600 according to another embodiment of the present disclosure. Figure 6As shown, the video quality assessment method 600 may include steps S601, S602, S603, S604, S605, S606, S607, S608 and S609. The method 600 may be executed for each quality assessment dimension to determine a quality assessment result of the video in the quality assessment dimension.

[0087] First, in step S601 , it may be determined whether the current quality assessment dimension is applied to the quality assessment of the current video.

[0088] In an example, a set of quality assessment dimensions may be pre-set, such as Figure 5 The first level of the array 500 is shown. During video quality assessment, a set of quality assessment dimensions can be traversed to determine which quality assessment dimension(s) in the set have scores for the video segment, thereby determining the quality assessment dimensions or dimensions from which the video is assessed.

[0089] If the current quality assessment dimension does not have a score for the video segment, that is, it has not been applied to the quality assessment of the current video, then the assessment result judgment of the quality assessment dimension can be directly ended.

[0090] If the current quality assessment dimension has a score for the video segment, that is, it is applied to the quality assessment of the current video, then step S602 can be continued to sort the score values ​​under the quality assessment dimension from low to high to facilitate subsequent data traversal.

[0091] In this example, since the predetermined criteria corresponding to a lower score value are often a subset of the predetermined criteria corresponding to a higher score value, when both the predetermined criteria corresponding to the lower score value and the predetermined criteria corresponding to the higher score value are met, the lower score value can be given greater weight, and the final score can even be determined as the lower score value. Therefore, by sorting the scores under this quality assessment dimension from low to high and then traversing the data, the video assessment results can be determined more efficiently.

[0092] In this example, all score values ​​under the quality assessment dimension may correspond to predetermined judgment conditions including one or more strategies, or only some score values ​​may correspond to predetermined judgment conditions including one or more strategies. Each quality assessment dimension may include one or more quality assessment indicators, so each predetermined judgment condition of these quality assessment dimensions may also include one or more strategies. These strategies may be, for example, Figure 3 (the predetermined judgment condition corresponding to the quality assessment dimension includes a strategy) or Figure 4 As shown in FIG5 (the predetermined judgment condition corresponding to the quality assessment dimension includes two strategies), the content of each strategy may include a score, a type (ie, a quality assessment indicator), a condition, and a threshold.

[0093] For each strategy corresponding to each strategy score value under the quality assessment dimension, step S605 can be executed. In step S605, it can first be determined whether the type (i.e., quality assessment indicator) in the content of the strategy is the number of times, duration, or duration ratio. By traversing Figure 5 The array 500 shown aggregates the data to obtain aggregated evaluation information of the video on the quality assessment dimension. The aggregated evaluation information may include the total number of times the quality problem corresponding to the quality assessment dimension appears in the entire video, the cumulative duration, and the proportion of the cumulative duration in the entire video duration. In some embodiments, when the quality assessment of the video involves the quality assessment dimension, but the video reviewer does not assign a score to the video on the quality assessment dimension, the quality assessment dimension can be configured as a score value of "all". In this case, the number of video segments can be directly accumulated to obtain the total number of times, or the duration of the video segments can be accumulated to obtain the cumulative duration, and the proportion of the cumulative duration in the entire video duration can be further obtained without traversing such as Figure 5 The array 500 shown aggregates the data. Based on the aggregated evaluation information on the quality evaluation dimension and the predetermined judgment conditions of the policy, the evaluation result of the policy can be determined. If the aggregated evaluation information on the quality evaluation dimension meets the predetermined judgment conditions of the policy, a Boolean value "true" can be output.

[0094] In step S606, it can be determined whether the score value corresponds to multiple strategies. If the score value corresponds to multiple strategies, then step S607 can be executed, and the result of this round (i.e., the Boolean value output by the current strategy) and the result of the previous round (i.e., the Boolean value obtained after the logical operation of all previous strategies) can be logically operated to update the output Boolean value. When this strategy is the first strategy corresponding to the score value, step S607 can be skipped. The logical operation relationship can also be pre-set in the strategy. If the logical operation relationship is set to "||", then when at least one of the Boolean value output by this strategy and the Boolean value obtained after the logical operation of all previous strategies is "true", the Boolean value "true" can be output. If the logical operation relationship is set to "&&", then when the Boolean value output by this strategy and the Boolean value obtained after the logical operation of all previous strategies are both "true", the Boolean value "true" can be output.

[0095] Next, in step S604, a determination is made as to whether all policies corresponding to the score value have been traversed. If not, steps S605 through S607 are continued until all policies corresponding to the score value have been traversed. Once all policies corresponding to the score value have been traversed, step S608 is executed to determine whether the current score value matches. If the score value corresponds to only one policy, this means that all policies corresponding to the score value have been traversed in step S606, and the process can then jump to step S608.

[0096] In step S608, if the Boolean value obtained at this time is "true", it can be said that it can match the current score value, and the score value is the final quality assessment result on the quality assessment dimension, and the assessment result judgment of the quality assessment dimension is completed.

[0097] If the Boolean value obtained at this time is not "true", it may indicate that the current score value has not been matched. In this case, step S603 may be used to determine whether all policies corresponding to all score values ​​have been traversed. If there are other score values ​​corresponding to policies under this quality assessment dimension, steps S604, S605, S607, and S608 may be performed for the next score value corresponding to a policy. If there are no other score values ​​corresponding to policies under this quality assessment dimension, step S609 may be performed to determine that the score is "null", indicating that this quality assessment dimension has no final score. At this point, the evaluation result judgment for this quality assessment dimension ends.

[0098] According to some embodiments, Figure 2 The video quality assessment method 200 shown or Figure 6 The video quality assessment method 600 may further include: obtaining updated quality assessment data; and re-determining a quality assessment result of the video based on the updated quality assessment data.

[0099] In this example, the updated quality assessment data may be the same as or different from the original quality assessment data. The updated quality assessment data may add new video segment data to the original quality assessment data, modify data related to one or more video segments in one or more quality assessment dimensions in the original quality assessment data, or delete data related to one or more video segments in one or more quality assessment dimensions in the original quality assessment data.

[0100] In this example, if the video reviewer believes that the original quality assessment data is missing, they can supplement and report the newly added quality assessment data. In this case, the value of the new time point can be used as the field of the hash structure, and the new video segment can be added as the value of the hash structure. Then, based on the updated quality assessment data, the video quality assessment result can be re-determined using the video quality assessment method of the above embodiment.

[0101] In this example, if the video reviewer believes that the original quality assessment data contains errors, they can logically delete the corresponding portion of the quality assessment data. In this case, the value of the time point corresponding to the video segment to be deleted can be used as the field of the hash structure to search and delete the corresponding hash structure value. Then, based on the updated quality assessment data, the video quality assessment result can be re-determined using the video quality assessment method of the above embodiment.

[0102] According to an embodiment of the present disclosure, by re-determining the quality evaluation result of the video when the quality evaluation data is updated, the quality evaluation result of the video can be corrected in time to ensure the accuracy of the quality evaluation result of the video.

[0103] According to some embodiments, Figure 2 The video quality assessment method 200 shown or Figure 6 The illustrated video quality assessment method 600 may further include: receiving a request to display a quality assessment result of the video; and displaying the quality assessment result of the video.

[0104] Figure 7 A schematic diagram showing a video quality assessment result according to an embodiment of the present disclosure is shown.

[0105] See also Figure 7 The display interface of the video quality evaluation result includes a video browsing frame, a current video information frame, a current video standard information frame and a video quality evaluation result display frame. Figure 7 The video quality assessment results shown in the figure show that the video shown on the left is evaluated for multiple picture-related quality assessment dimensions such as watermark / advertising issues, picture truncation, mosaics, and picture correlation, and the final scores of the video on these quality assessment dimensions are shown.

[0106] According to the embodiment of the present disclosure, by displaying the quality evaluation result of the video, the user can intuitively obtain the quality evaluation result of the video.

[0107] According to another aspect of the present disclosure, a network configuration device is also provided.

[0108] Figure 8 FIG. 8 is a structural block diagram of a video quality assessment apparatus 800 according to an embodiment of the present disclosure.

[0109] like Figure 8 As shown, the video quality assessment apparatus 800 includes: a data acquisition module 810 configured to acquire quality assessment data for a video comprising multiple video segments. The quality assessment data includes a score on at least one quality assessment dimension; a score determination module 820 configured to determine, for each quality assessment dimension, a score for at least one video segment evaluated on the quality assessment dimension from among the multiple video segments; and a result determination module 830 configured to determine a quality assessment result for the video based on one or more video segments from among the at least one video segment having a predetermined identical score.

[0110] Since the data acquisition module 810, the score determination module 820, and the result determination module 830 in the video quality assessment apparatus 800 may correspond to the following Figure 2 The steps S201 to S203 are described, so the details of each aspect are not repeated here.

[0111] In addition, the video quality assessment apparatus 800 and the modules included therein may further include submodules, which will be described in conjunction with the following. Figure 9 Provide detailed explanation.

[0112] According to an embodiment of the present disclosure, the quality assessment result of the video is determined by determining the respective scores of at least one video segment evaluated on each quality assessment dimension among multiple video segments based on the quality assessment data uploaded by the video reviewer. The final score of the video on each quality assessment dimension can be automatically calculated according to predetermined rules or judgment conditions. Compared with manual statistics of video quality scores, the efficiency is greatly improved, and the accuracy of data calculation is also guaranteed, making the video quality assessment result more accurate and reliable.

[0113] Figure 9 FIG. 4 shows a structural block diagram of a video quality assessment apparatus 900 according to another embodiment of the present disclosure.

[0114] like Figure 9 As shown, the video quality assessment apparatus 900 may include a data acquisition module 910, a score determination module 920, and a result determination module 930. The data acquisition module 910, the score determination module 920, and the result determination module 930 may be used together with the following examples: Figure 8 The data acquisition module 810, score determination module 820, and result determination module 830 shown correspond to each other, so their details are not repeated here.

[0115] In an example, each quality assessment dimension may include at least one quality assessment indicator, where the at least one quality assessment indicator includes at least one of the number of times, duration, and duration ratio. Result determination module 930 may include a condition judgment module 931 configured to determine a quality assessment result for the video based on whether the at least one quality assessment indicator satisfies a predetermined judgment condition for one or more video segments having the same predetermined score.

[0116] Therefore, by automatically calculating the final score of the video in each quality assessment dimension based on predetermined judgment conditions, the video quality assessment result can have higher accuracy and reliability compared with manual subjective scoring.

[0117] In an example, in response to each quality assessment dimension including at least two quality assessment indicators, a predetermined logical operation relationship may exist between the at least two quality assessment indicators to constitute a predetermined judgment condition.

[0118] Therefore, by connecting at least two quality assessment indicators with a predetermined logical operation relationship to form a predetermined judgment condition, the video can be scored in each quality assessment dimension from multiple angles at the same time, thereby further improving the reliability of the video quality assessment result.

[0119] In an example, for each quality assessment dimension, a mapping relationship between a score on the quality assessment dimension and one or more video segments corresponding to the score may be stored in the quality assessment data. Score determination module 920 may include: a video segment search module 921 configured to find one or more video segments corresponding to the score based on the score on the quality assessment dimension based on the mapping relationship; and a video segment scoring module 922 configured to determine the scores of the one or more video segments.

[0120] Therefore, by storing the quality assessment data of the video in a mapping relationship between the scores on the quality assessment dimensions and the video segments corresponding to the scores, it is possible to easily determine the aggregated assessment information of the video on each quality assessment dimension, such as the total number of times the quality problem corresponding to the quality assessment dimension appears in the entire video, the cumulative duration, and the proportion of the cumulative duration in the entire video duration. At the same time, the quality assessment data of the video stored in this way can also make it easier for video reviewers to control the progress of the video quality assessment and trace the quality assessment data. When it is necessary to add, modify or delete video segment information, the quality assessment data can be updated efficiently.

[0121] In an example, the apparatus 900 may further include: a data updating module 940 configured to obtain updated quality assessment data; and a result updating module 950 configured to re-determine a quality assessment result of the video based on the updated quality assessment data.

[0122] Therefore, by re-determining the quality evaluation result of the video when the quality evaluation data is updated, the quality evaluation result of the video can be corrected in time to ensure the accuracy of the quality evaluation result of the video.

[0123] In an example, the apparatus 900 may further include: a request receiving module 960 configured to receive a request for displaying a quality assessment result of a video; and a result display module 970 configured to display the quality assessment result of the video.

[0124] Therefore, by displaying the quality evaluation result of the video, the user can intuitively obtain the quality evaluation result of the video.
