Description
Technical Field
The invention relates to a multimedia playing method and a multimedia playing system based on the state matching of a user terminal and video resolution, in particular to reasonable utilization of videos with different resolution types provided by a server side.
Background
In order to meet the requirements of users for different resolutions of videos, the videos provided by the server side have more than one resolution type, and usually have several resolution types for selection, 360P, 720P and 2K. In a current video playing method of a mobile device client (user terminal for short), mainly aiming at videos with resolution types of 360P, 720P, 2K and the like, a user can select a video with a corresponding resolution to play by himself, and the user terminal can also select a video with a resolution matched with a network speed to play according to the network speed of the user terminal.
With the appearance of 4K and 8K ultra-high definition videos in videos provided by a server, the network transmission capacity, the storage capacity and the computing capacity of a user terminal are updated, the selectable resolution types of users are increased, the requirements of the users playing the videos with various resolutions are different, the videos are played only according to the network speed and the resolution type selected by the users, and the influence of other states of the user terminal on the video watching experience is ignored.
In particular, whether the resolution of the video is large or small, there are respective advantages and disadvantages: the video with lower resolution is not clear in image quality, but has low requirements on the network transmission speed, the storage capacity and the operational capacity of the user terminal, and can be smoothly played at the user terminal with low network speed or poor performance; the resolution ratio is ultra-high definition 4K and 8K videos, the image quality is clear, the color is full, but the requirements on the network transmission speed and the storage capacity and the computing capacity of the user terminal are very high, and the phenomenon of pause can occur in the playing process of the user terminal in the network speed environment or insufficient operation.
Therefore, there are differences in user's preference for video, network environment where the user terminal is located, and performance of the user terminal, resulting in differences in user's demands for video resolution types. For example, users who like to watch self-timer short videos, users who use low-performance mobile phones, and users who play videos using traffic tend to select to watch low-resolution videos, so as to ensure that the short videos can be played smoothly and continuously with less consumption traffic; users who like to watch documentaries or action movies, and users who use large-screen mobile terminals such as tablet computers tend to select to watch high-resolution videos, so that the users can watch more shocky and faster. For different user requirements, the user simply selects each resolution type through network speed or the user selects each resolution type, and the method is not intelligent and diversified.
In addition, the screen size of the mobile user terminal is much smaller than that of a television and a computer display screen, the difference of visual effects of watching high definition (1080P) videos and super high definition (4K) videos is very small, and the visual effect obtained by a user is obviously not proportional to the operation and memory cost of the user terminal.
In the prior art, a playing method for reasonably combining user preference, network speed, user terminal running and storage resources and screen resolution is not available, so that the advantages of user terminal resources or video resources of various resolution types are difficult to be fully exerted, and the viewing experience of a user is not favorably improved.

2. Since the corrected priority value PXv is obtained by correcting the primary priority value Pv, for example, the video playing strategy of the user can be reflected in the selection of the video resolution type by correction, so that the playing of the video is more suitable for the subjective feeling of the user.

The flow of the primary priority value determination step is explained below.
Fig. 5 is a flowchart illustrating the primary priority value determination step.
As shown in fig. 5, the primary priority value determination step S300 includes the following sub-steps:
the coordinate system establishing step S310 establishes a planar direct coordinate system in which the width of the resolution is the horizontal axis and the height of the resolution is the vertical axis.
The diagonal endpoint determining step S320 is to determine diagonal endpoints with corresponding resolutions by using the screen resolution of the user terminal 1 and the widths and heights of the resolutions of various resolution types of the video played by the server side 2 as coordinates. For example, as shown, the video has a total of M resolutions, i.e., diagonal endpoints of M corresponding resolutions are determined.
And S330, determining rectangles corresponding to each diagonal line, namely setting the origin of the coordinate system as a common endpoint, and determining the rectangles corresponding to the screen resolution of the user terminal and each resolution type of the server-side video according to the screen resolution of the user terminal and the diagonal endpoints corresponding to each resolution type of the server-side video respectively, wherein each side of each rectangle is vertical or parallel to a coordinate axis.
A matching coefficient calculating step S340 of calculating matching coefficients WHv (v =1 … m) of various resolution types of the played video and the user terminal by the following expressions:
in the above expression, WH v Matching coefficient of a v-th resolution type of the server side video and the mobile terminal equipment, wherein v is the serial number of the server side video resolution type, M is the screen resolution of the mobile terminal equipment, k is the expansion coefficient of the mobile terminal equipment, M.k represents a rectangle formed in a coordinate system after the mobile terminal equipment expands by k times, A MK Is the area of the rectangle corresponding to M.k, C v Is a rectangle corresponding to the server-side video nth resolution type in the coordinate system,
is C v Area of the corresponding rectangle, R MK Is a matching factor.
The expansion coefficient k is a constant larger than 1, the k values corresponding to different screen resolutions are different, and the larger the screen resolution is, the larger the k value is. Assuming that the screen resolution of the user terminal 1a is 2376 pixels × 1080 pixels, and k =1.2, the width and height of the rectangle M · k is 1.2 times the width and height of the screen resolution, i.e., 2851.2 pixels × 1296 pixels. It is considered that the resolution value corresponding to the width and height of the rectangle M · k is a limit of the resolution display sharpness effect that the user can experience with the naked eye, that is, the difference in the visual effect of the video resolution corresponding to the width and height of the rectangle M · k is extremely small and cannot be distinguished with the naked eye of the user. The k value can be adjusted according to the test result.
Matching factor R MK Is a constant greater than 0 and less than 1, and R is corresponding to different screen resolutions MK Different values, the larger the typical screen resolution, R MK The smaller the value. R MK The function of (1) is to adjust the calculation result of the matching coefficient WHv, and when the screen resolution is large, R can be set MK Closer to 0, resulting in a matching coefficient WHvThe calculation of (2) is larger. R MK The value of (c) can be adjusted according to the test results.
As shown in FIG. 5, the rectangle intersection judging step S340a judges the rectangles M.k and C v (v =1 … m), if the intersection is equal to rectangle C v (v＝1…m)；
If not equal, the width and/or height of the rectangle M.k exceeds the rectangle C v A range of (1), considered as a rectangle C v The corresponding video resolution exceeds the limit of resolution display definition effect which can be experienced by naked eyes of a user, and the matching coefficient WH is v ＝0。
If equal, the width and height of the rectangle M.k do not exceed the rectangle C v A range of (1), considered as a rectangle C v The corresponding video resolutions are clearly distinguishable under the visual recognition of the user. Matching coefficient at this time
Through the above calculation, matching coefficients WHv (v =1 … m) corresponding to various video resolutions are obtained.

The flow of the primary priority value correction step 400 will be described below.
Fig. 6 is a flowchart illustrating the primary priority value correction step.
Before playing the video, the user selects one of the playing strategies in the user terminal in advance. The playing strategy comprises the following steps: the video definition is preferred, the equipment resource is saved preferably, the video fluency is preferred, and the resolution matching is preferred.
In the preliminary preference value correction step S400, correction priority values PXv (v =1 … m) of various resolution types under different playback strategies are calculated by the following expressions.
As shown in fig. 6, the primary priority value modification module 400 reads the playing policy and determines whether the playing policy is "when video definition is prioritized", and if so, calculates PX v ＝P v ·D v (ii) a If not, judging whether the playing strategy is 'when the resource of the equipment is saved preferentially', if so, calculating
If not, judging whether the playing strategy is 'when the video is fluent and has priority', if so, calculating->
If not, judging whether the playing strategy is 'when the resolution ratio is matched with the priority', if so, calculating PX v ＝P v ·WH v And if not, the playing strategy is read again.
The corrected priority values PXv (v =1 … m) of the respective resolution types can be obtained by calculation.
The correction priority value PXv includes information of screen resolution, video resolution, network transmission speed, memory resource occupancy rate and operation resource occupancy rate, and a user selects different playing strategies to obtain corresponding calculation results, so that the user terminal can play videos with corresponding resolutions according to the playing strategies selected by the user.
Due to the matching coefficient WH v And =0, the modified priority value PXv =0, so that when the video resolution type selection step S500 performs size sorting, the corresponding modified priority value PXv is arranged at the end, that is, the corresponding video resolution type can be removed, and the user does not play the video without manually modifying the resolution type, so that the operation cost of the user terminal and the visual experience of the user can be both considered, and the playing effect is more reasonable.
By the expression, screen resolution, network transmission speed, operation resources, memory resources and video resolution can be used as parameters, reasonable correlation calculation is carried out on each parameter according to a playing strategy preferred by a corresponding user, and then a corresponding video resolution type is selected to be played according to a calculation result. Therefore, the influence factors such as screen resolution, network transmission speed, operation resources, memory resources, video resolution and the like are combined with the user preference in a multi-element manner, the advantages of the user resource terminal and the video resources with various resolution types are fully exerted, and the watching experience of the user is improved.
As a modification, the server 2 reads the user terminal status of the user terminal 1a … … n, calculates the primary priority value and the correction priority value corresponding to each user terminal according to the video resolution type information, sorts the correction priority values, and selects a video with a suitable resolution type to be transmitted to each user terminal for playing.
Examples

The video provided by the server 2 has three video resolution types (2560 pixels by 1440 pixels, 1920 pixels by 1080 pixels, 1024 pixels by 720 pixels). The network transmission speed of the user terminal 1a is 2.8M/s, the memory resource occupancy rate is 60%, the operation resource occupancy rate is 40%, the value of the memory resource factor is 3, and the value of the operation resource factor is 4.

The following describes a specific calculation procedure of the primary priority value Pv (v =1, 2, 3) with reference to fig. 7 to 12:
the coordinate system establishing module 310 establishes a planar direct coordinate system with the width of the resolution as the horizontal axis and the height of the resolution as the vertical axis (step S310), i.e., the coordinate system in fig. 7-12.
The diagonal line endpoint determining module 320 determines diagonal line endpoints with corresponding resolutions by using the screen resolution of the user terminal 1 and the width and height of the resolutions of various resolution types of the video played by the server side 2 as coordinates respectively (S320), sets the origin of the coordinate system as a common endpoint, and determines corresponding rectangles M · k and C according to the corresponding diagonal line endpoints 1 Rectangle C 2 Rectangle C 3 。
As shown in fig. 7, the coordinate value of the end point of the rectangle M · k is 1.2 times the screen resolution (2376,1080) of the user terminal 1a, and the diagonal end point is determined to be (2851.2,1296), that is, the rectangle M · k can be determined. (Steps S320a, S330 a)
As shown in fig. 8, the rectangle C1 corresponds to a video resolution type of 2560 pixels x 1440 pixels, and the diagonal ends are (2560, 1440); as shown in fig. 9, the video resolution type corresponding to rectangle C2 is 1920 pixels by 1080 pixels, and the diagonal end point is (1920,1080); as shown in fig. 10, rectangle C3 corresponds to a video resolution type of 1024 pixels by 720 pixels with diagonal endpoints (1024,720). The rectangle C1, the rectangle C2 and the rectangle C3 can be determined. (Steps S320b, S330 b)
According to the expression
The calculation was performed as follows:
respectively judging (M, k) # C v And C v The relationship of (1):
as shown in FIG. 11, the diagonal lines in FIG. 11 are filled with a rectangle M.k, and the vertical lines are filled with a rectangle C 1 Filling the crossing lines with (M.k) # C 1 Obviously, (M.k) # C 1 ≠C 1 (step S340 a), so the resolution type is the matching coefficient WH of 2560 pixels 1440 pixels 1 =0 (step S340 b).
As shown in FIG. 12, the diagonal lines in FIG. 12 are filled with a rectangle M.k, and the vertical lines are filled with a rectangle C 2 Filling the crossing lines with (M.k) # C 2 It is obvious that (M.k) # C 1 ＝C 1 (step S340 a), so the resolution type is 1920 pixels by 1080 pixels of matching coefficient
(two decimal places are reserved for the calculation results in the current time and the following text; the process of substituting numbers is omitted for the calculation in the following text).
Using the same method, a matching coefficient WH of a resolution type of 1024 pixels by 720 pixels can be calculated 3 =1.40 (step S340 f).

the video resolution type selection module 500 sorts the correction priority values PXv (v =1, 2, 3), and selects a video of a video resolution type having the maximum correction priority value PXv (v =1, 2, 3) from the server side 2 to play (step S500).
The following lists the calculation results of the user selecting various play strategies:
when the user selects the playback strategy to be "when the video definition takes precedence" (step S420 a), the calculation result of the correction priority value PXv (step S430a, step S440) is as shown in table 4:
TABLE 4
| v | Video | PXv | |
| 1 | 2560*1440 | 0 | |
| 2 | 1920*1080 | 2.79 | |
| 3 | 1024*720 | 0.95 |
PX2 > PX3 > PX1 (2.79 > 0.95 > 0), so the user terminal 1a plays back a video having 1920 pixels by 1080 pixels in the video resolution type corresponding to the correction priority value PX2 having the largest numerical value.
When the user selects the playback strategy to be "when the saving device resources are prioritized" (step S420 b), the calculation result of the corrected priority value PXv (step S430b, step S440) is as shown in table 5:
TABLE 5
| v | Video | PXv | |
| 1 | 2560*1440 | 0 | |
| 2 | 1920*1080 | 0.65 | |
| 3 | 1024*720 | 1.73 |
PX3 > PX2 > PX1 (1.73 > 0.65 > 0), so that the user terminal 1a plays back the video of 1024 pixels by 720 pixels in the video resolution type corresponding to the correction priority value PX3 having the largest numerical value.
When the user selects the playback strategy "when the video smoothness takes precedence" (step S420 c), the calculation result of the modified priority value PXv (step S430c, step S440) is as shown in table 6:
TABLE 6
| v | Video | PXv | |
| 1 | 2560*1440 | 0 | |
| 2 | 1920*1080 | 1.38 | |
| 3 | 1024*720 | 2.42 |
PX3 > PX2 > PX1 (2.42 > 1.38 > 0), so that the user terminal 1a plays back the video of 1024 pixels by 720 pixels in the video resolution type corresponding to the correction priority value PX3 having the largest numerical value.
When the user selects the playback strategy as "when resolution matching is prioritized" (step S420 d), the calculation result of the corrected priority value PXv (step S430d, step S440) is as shown in table 7:
TABLE 7
| v | Video | PXv | |
| 1 | 2560*1440 | 0 | |
| 2 | 1920*1080 | 1.38 | |
| 3 | 1024*720 | 2.42 |

In summary, for the user selecting different playing strategies, the user terminal 1a finally plays the video with the corresponding resolution type, and the summary of the playing results is shown in table 8:
TABLE 8
From the contents listed in table 8, the 2560 pixels 1440 pixels of video will not be played regardless of the playback strategy selected by the user, as long as the video resolution is not modified manually, since 2560 pixels 1440 are beyond the limit of resolution display definition effect that the user can experience with the naked eye.
After removing the videos with 2560 pixels by 1440 pixels, the videos with 1920 pixels by 1080 pixels are the clearest and are most matched with the screen resolution, so that when a user selects a playing strategy of 'priority on video definition' and 'priority on resolution matching', the videos with 1920 pixels by 1080 pixels can be watched.
The 1024 pixel by 720 pixel video has the minimum requirements on the operation resources, the memory resources and the network transmission speed of the user terminal, so that when the user selects the playing strategy of saving equipment resources and giving priority to the video fluency, the user can view the 1024 pixel by 720 pixel video.
And when the playing is finished, updating the state of the user terminal.
