Fig. 2 schematically shows a flow chart of a data processing method according to an embodiment of the present disclosure.
The data processing method is applied to a mobile terminal, and as shown in fig. 2, the data processing method includes operations S210 to S230.
In operation S210, in the process of outputting the first segment of the multimedia file, the network parameters of the network environment where the mobile terminal is currently located and the current device operating parameters of the mobile terminal are obtained, where the first segment of the multimedia file is obtained from the server side.
According to embodiments of the present disclosure, the multimedia file may be a video, a document, or the like.
According to the embodiment of the disclosure, before the mobile terminal outputs the first segment of the multimedia file, the mobile terminal may send an acquisition request for acquiring the multimedia file to the server side, the server side responds to the acquisition request from the mobile terminal, first sends the first segment of the multimedia file to the mobile terminal, and the mobile terminal receives the first segment of the multimedia file sent from the server side.
According to an embodiment of the present disclosure, the network parameters may include at least one of: download rate, delay time, packet loss rate; the device operating parameters may include at least one of: the processor processes the rate, the remaining memory space, and the battery level.
In operation S220, a play quality level of the mobile terminal is determined according to the network parameter and the device operation parameter.
According to the embodiment of the disclosure, for example, the playing quality level of the mobile terminal can be determined according to the download rate and the remaining memory space; or, determining the playing quality grade of the mobile terminal according to the downloading rate and the battery power; or, the playing quality grade of the mobile terminal is determined according to the download rate, the delay time, the packet loss rate, the processing rate of the processor, the remaining memory space and the battery power, and the like.
According to the embodiment of the present disclosure, the playing quality level may be a quantization level, for example, a first level playing quality, a second level playing quality, a third level playing quality, and the like, where fluency is different when playing the video in the playing quality of different levels.
According to the embodiment of the disclosure, in the video playing process, the playing quality of a video is monitored in real time through the client side of the mobile terminal, the current playing quality is graded through acquiring the download rate of the network where the mobile terminal is located, the network delay and the battery power of the current equipment at the mobile terminal, the current playing quality of the mobile terminal is not calculated through analyzing and predicting the previous data at the server side, and the processing pressure of the server side is reduced.
In operation S230, the playing quality level of the mobile terminal is sent to the server, so that the server determines the bitrate of the second segment of the multimedia file according to the playing quality level of the mobile terminal.
According to the embodiment of the disclosure, different segments of the multimedia file respectively have corresponding code rates. For example, the first segment corresponds to a first code rate and the second segment corresponds to a second code rate. According to the embodiment of the present disclosure, the time duration of the slice is not limited, and for example, may be 2 seconds, and each slice may correspond to a video slice of 2 seconds.
According to the embodiment of the disclosure, when a user watches videos in a network environment, when a video server receives a user watching request, a video source can be immediately subjected to slicing with fixed time length and conversion of different video code rates, a first slicing (for example, the slicing time length is 3s) returned to the user is a video slicing with the lowest code rate, so that the later slicing can be cached, and by setting the code rate of the first slicing to be the lowest, smooth playing of the videos at the beginning can be ensured, meanwhile, the users can be ensured to watch the videos at least smoothly, and the lowest experience requirement of the users is met. Of course, the code rate of the first segment may not be the lowest, and is not described herein again.
According to the embodiment of the disclosure, for example, in the process of outputting the first segment of the multimedia file, the playing quality grade of the mobile terminal is "poor", and after the server receives the playing quality grade "poor" sent by the mobile terminal, the code rate of the second segment of the multimedia file can be smaller than or equal to the code rate of the first segment, so that the second segment can be ensured to be transmitted to the mobile terminal more stably as far as possible, and the mobile terminal cannot be jammed. According to the embodiment of the disclosure, the code rate may be the number of sampling times in a unit time, and the higher the code rate is, the higher the definition of the video is, and the larger the data amount is.
According to the embodiment of the disclosure, the server may segment the multimedia file in advance to obtain a plurality of segments including a first segment, each segment has one or more corresponding candidate code rates, and the code rate of the first segment is the lowest.
According to the embodiment of the present disclosure, it should be noted that, in a case that the bitrate of a first segment (which may be, for example, the first segment of a video) is the lowest, the bitrate of a subsequent segment is greater than or equal to the bitrate of the first segment. However, the size relationship between the code rates of the subsequent slices is not limited. For example, the code rate of the third segment may be lower than/equal to/higher than the code rate of the second segment, wherein when the code rate of the third segment is lower than the code rate of the second segment, the code rate of the second segment needs to be higher than the code rate of the first segment.
According to the embodiments of the present disclosure, it should be noted that the terms "first segment", "second segment", and "third segment" and the like in the description and the drawings of the present disclosure are used to distinguish different objects, where the "first segment" may not only represent a first segment in a multimedia file, the "second segment" may not only represent a second segment in the multimedia file, and the "third segment" may not only represent a third segment in the multimedia file. In fact, any one of the clips in the multimedia file can be referred to as a "first clip", a "second clip", and a "third clip" in the case that the playing or transmission order is satisfied. For example, the first segment may be a fourth segment in a multimedia file, the second segment may be a fifth segment in a multimedia file, and the third segment may be a sixth segment in a multimedia file.
According to the embodiment of the disclosure, the server may segment the multimedia file in advance to obtain a plurality of segments including the first segment, and each segment has one or more corresponding candidate code rates. Under the condition that the server side obtains the playing quality grade sent by the mobile terminal, the server side can determine the code rate of the second segment of the multimedia file according to the playing quality grade of the mobile terminal.
According to the embodiment of the disclosure, the determining, by the server side, the code rate of the second segment of the multimedia file according to the playing quality grade of the mobile terminal includes: and the server determines the code rate of the second segment of the multimedia file from the one or more candidate code rates of the second segment according to the playing quality grade of the mobile terminal.
According to the embodiment of the disclosure, if the code rate adapted to the playing quality level is not within the range of the one or more candidate code rates, the code rate of the segment may be dynamically adjusted to a new code rate outside the range of the one or more candidate code rates. That is, the server may also dynamically adjust one or more candidate code rates of the second segment to a code rate adapted to the playing quality level according to the playing quality level of the mobile terminal.
According to the embodiment of the disclosure, when the server side fragments the multimedia file in advance, the server side can transcode other fragments except the first fragment in the plurality of fragments in advance according to one or more candidate code rates corresponding to the other fragments, so as to generate backups with different code rates for each of the other fragments.
According to the embodiments of the present disclosure, for example, the server side may generate a plurality of backups corresponding to a plurality of candidate bit rates for each segment. Specifically, for example, before the first segment is transmitted, candidate bitrate of the second segment is set in advance, 4 second segment backups corresponding to the 4 candidate bitrate are set in advance (the second segment backups may be encoded into the 4 backups in advance), then bitrate of the second segment of the multimedia file is determined from the 4 candidate bitrate of the second segment according to the playing quality level of the mobile terminal, and then the determined second segment backup corresponding to bitrate is selected for transmission.
According to the embodiment of the disclosure, the server side may not generate backups with different code rates for each segment, and may only select some segments in the multimedia file for backup.
According to the embodiment of the disclosure, the multimedia file (such as a video source) can be sliced in advance on the server according to fixed time, and backups with different code rates are prepared for each slice, so that when code rate selection is performed according to the playing quality grade, transcoding time can be saved, and the slice with the code rate corresponding to the playing quality grade can be directly issued.
According to the embodiment of the disclosure, before the first segment is transmitted, the server side does not need to set the code rate of the second segment in advance, after the playing quality grade of the mobile terminal is obtained, after the code rate is determined according to the playing quality grade of the mobile terminal, transcoding is directly performed according to the determined code rate, and then the second segment is transmitted. According to the embodiment of the disclosure, the second segment is transmitted after transcoding is directly carried out according to the determined code rate, transcoding backup is not carried out in advance, and memory occupation of a server can be reduced. According to the embodiment of the disclosure, for example, in the process of outputting the first segment of the multimedia file, the playing quality level of the mobile terminal is "better", and after the server receives the playing quality level "better" sent by the mobile terminal, the code rate of the second segment of the multimedia file can be greater than that of the first segment, so that the definition of the video can be improved, and the user experience can be improved.
According to the embodiment of the disclosure, the playing quality grade of the video watched by the current user can be obtained by analyzing the current network environment condition of the mobile terminal of the user and the running quality of the equipment, so that the code rate of the video fragments is dynamically adjusted according to different playing quality grades, the video playing is smoother, the video playing problem under the changeable network environment is processed in real time, and the watching experience of the user is improved.
According to the embodiment of the disclosure, in the process of outputting the first segment of the multimedia file by the mobile terminal, the playing quality grade of the mobile terminal is determined according to the current network parameter and the equipment operation parameter of the mobile terminal, and the playing quality grade is sent to the server, so that the server determines the code rate of the next segment according to the playing quality grade. The server side can determine the code rate of the next segment according to the playing quality grade, so that the server side does not need to run a complex algorithm, and the processing pressure of the server side is reduced; the playing quality grade of the mobile terminal is determined according to the current network parameters and equipment operation parameters of the mobile terminal, the playing quality grade can be evaluated in real time, then the code rate of the next segment is dynamically adjusted, so that the playing of the multimedia file is smoother, and the code rate switching strategy can be adaptively adjusted according to the situation that the network environment changes, so that the technical problem that the smoothness requirement of the mobile terminal for playing the video cannot be met by adopting the related technology is at least partially overcome, the smoothness of the played video is improved, and the technical effect of watching experience of a user is improved.
The method shown in fig. 2 is further described with reference to fig. 3-5 in conjunction with specific embodiments.
Fig. 3 schematically illustrates a flow chart for determining a playback quality level of a mobile terminal based on network parameters and device operating parameters according to an embodiment of the disclosure.
According to the embodiment of the present disclosure, as shown in fig. 3, determining the playing quality level of the mobile terminal according to the network parameter and the device operation parameter includes S310 to S330.
In operation S310, it is determined whether the network parameter satisfies a first preset condition;
according to an embodiment of the present disclosure, for example, a download rate and a delay may be used as network parameters for evaluating a network condition, the download rate may be in kb/s, and the delay time may be in ms. The first preset condition may be that the download rate is greater than or equal to 100kb/s and the delay time is greater than or equal to 100 ms.
In operation S320, under the condition that the network parameter satisfies the first preset condition, determining whether the device operation parameter satisfies a second preset condition;
according to the embodiment of the disclosure, for example, when the value corresponding to the current network parameter downloading rate is greater than 100kb/s and the delay time is greater than 100ms, whether the device operation parameter meets the second preset condition is further determined. For example, the device operating parameter may be a battery level, and the second predetermined condition may be that the battery level is greater than or equal to 20% of a full capacity.
According to the embodiment of the present disclosure, in the case that the network parameter does not satisfy the first preset condition, the play quality level of the mobile terminal may be determined as a preset level. For example, the predetermined level may be "poor", which indicates that the network environment is not good.
In operation S330, in case that the device operation parameter satisfies a second preset condition, the network parameter and the device operation parameter are calculated according to a first preset formula, and the playing quality level of the mobile terminal is determined according to a first result obtained by the calculation.
According to an embodiment of the present disclosure, the first preset formula is not limited. Taking the network parameters as the download rate and the delay time, and the device operation parameters as the battery level, the following formula (one) may be used:
Z＝(W1*V+W2*D+W3*B)*R：
where Z represents the calculated playback quality level, V represents the download rate in kb/s, D represents the delay time in ms, and B represents the battery level in%. W1, W2 and W3 are weights that the download rate, delay, battery level have, respectively. In general, W1 and W2 can be 1/250 and-1/100 respectively; in the case where the battery level satisfies the second preset condition, for example, the battery level is greater than 40% of the full capacity, W3 may take 0. R is the weighting coefficient of the formula, and can be 0.9 or 1, and the like. The value of Z can be between [1, 4 ]. The server side can send the fragments with corresponding code rates to the mobile terminal according to the transmitted playing quality grade, so that the watching fluency of the user is improved.
Fig. 4 schematically illustrates a flow chart for determining a playback quality level of a mobile terminal based on network parameters and device operating parameters according to another embodiment of the present disclosure.
As shown in fig. 4, in operation S340, in the case that the device operation parameter does not satisfy the second preset condition, the network parameter and the device operation parameter are calculated according to the second preset formula, and the play quality level of the mobile terminal is determined according to the calculated second result.
According to an embodiment of the present disclosure, the second preset formula is not limited. Taking the network parameters as the download rate and the delay time, and the device operation parameters as the battery level as an example, the following formula (two) may be used:
Z＝(W1*V+W2*D)*W3*B*R；
the definition of the parameters in the formula (two) is the same as that of the parameters in the formula (one), and the value of each parameter can refer to the value range in the formula (one).

When the percentage of the battery capacity B to the full-grid capacity is greater than 40% and less than 40%, the playing quality level of the mobile terminal can be determined according to different calculation formulas.
According to the embodiment of the disclosure, the network environment condition can be evaluated through factors such as download rate, delay time, packet loss rate and the like. Specifically, the network environment condition can be evaluated, for example, with reference to the following formula (iii).
T＝K*(L*Al+U*Au+J*Aj+D*Ad+C*Ac)；
Where T is the network environment, the coefficient K is the weight factor for normalizing the whole formula, and L, U, J, D and C represent packet loss rate, burstiness, jitter, delay time, and available current bandwidth, respectively. Al, Au, Aj, Ad, Ac are the weights of the corresponding parameters, respectively. From the equation (three), it can be seen that the relation between the delay time and the download rate and W is linear, and given packet loss rate, burstiness and jitter, Al, Au, Aj, Ad and Ac in the equation can take-1/100, 0.5, [1, 5], respectively.
According to the embodiment of the disclosure, the battery power has never been taken as a reference factor in a video bitrate selection strategy in the field, and the disclosure creatively selects the battery power as a parameter for evaluating the condition of equipment. Because the battery capacity can reflect the current device status, the battery capacity will affect the battery performance and the device temperature, and thus the CPU running speed, and the corresponding relationship between the battery capacity and the battery capacity is shown in table 1.

| Electric quantity of battery | Influence of |
| Over 50 percent | Battery power downIs slower |
| 40％～50％ | The mobile phone performance is not greatly influenced, and the electric quantity is reduced quickly |
| 20％～40％ | The CPU processing rate begins to decrease and the electric quantity is lower |
| Less than 20% | The processing capacity of the mobile phone is obviously reduced, and the electric quantity is very low |

And then, monitoring the playing environment of the mobile terminal in real time at the client, acquiring the current downloading rate, network delay and battery power of the user in real time through a timing task, and calculating the playing quality grade. And finally, the server selects the fragment transmission with different code rates according to different playing quality grades, and provides the video fragment with the highest quality code rate on the premise of ensuring the watching fluency of the user as much as possible. According to the method and the device, the evaluation logic of the fragmentation code rate is completed at the client instead of prediction processing at the server, so that the processing load of the server can be reduced, and the real-time performance can be improved.
