Detailed Description
The core of the invention is to provide a self-adjusting playing method, a system and a device of an online video, the purpose of self-adjusting and optimizing the energy consumption of a battery is realized by dynamically adjusting the threshold value of a buffer, and the waste situation of network bandwidth is reduced to a certain extent when the user behavior is unstable.
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a flowchart illustrating a method for self-adjusting playing of an online video according to an embodiment of the present invention.
The self-adjusting playing method of the online video comprises the following steps:
step S1: after receiving an online video playing request, filling a group of video segments of a pre-played video into a preset buffer area, and controlling the periodic downloading of the video segments of the pre-played video through a preset buffer threshold value; wherein the buffer threshold characterizes the number of video segments downloaded at one merge.
In particular, merging and downloading a larger number of video segments is advantageous for reducing the power consumption of the terminal device in case the user's behavior pattern is in a steady state (in which the user neither jumps to another part of the current video nor exits the playing of the current video, i.e. the user is likely to watch the video online for a relatively long time). However, once the user's behavior pattern enters an unstable state (in this mode, even if the current video is not played completely, the user often jumps to another part of the current video, and may exit the playing of the current video, that is, the duration of time for the user to watch the same video is relatively short), a large number of merged downloaded video segments may be discarded, and these discarded video segments are not played at the client, which may cause a serious problem of wasting network bandwidth, and consume additional battery power. Merging and downloading a smaller number of video segments helps to reduce power consumption of the terminal device when the user's behavior pattern is in an unstable state.
Based on this, the present application sets the buffer threshold (representing the number of video segments downloaded in one merge) as an adjustable parameter, and sets a small initial value for the buffer threshold in advance (which may be the same as the amount of merging of video segments before optimization in the prior art). It should be noted that, before playing a new video each time, all the playing parameters should be initialized to prepare for waiting for the online video playing request of the user. This means that when an online video playing request comes, a new video will be played online or the playing jumps to a new video playing position using the original playing strategy.
After an online video playing request of a user is received, a group of video segments of a pre-played video corresponding to the online video playing request are immediately filled into a preset buffer zone at one time (called a buffer zone pre-fetching stage, the buffer zone is significant in that in order to prevent the situations of blocking and the like in the playing process of the video, a buffer zone is set in advance to be responsible for downloading and storing the video segments), so that the smooth playing of the pre-played video is realized. For downloading the later video segment of the pre-playing video, the present application controls the periodical downloading through the current buffer threshold.
Step S2: starting playing the pre-played video after the video segment is filled, counting the continuous online playing time of the pre-played video in real time, and judging whether the continuous online playing time exceeds a preset preheating time threshold value; if not, go to step S3; if yes, go to step S4.
Specifically, considering that the behavior pattern of the user is extremely unstable in the initial stage of video playback (referred to as the warm-up stage), the user is likely to jump to the playback of the video; with the increase of the continuous online playing time of the video, the user is more and more likely to watch the current online video for a long time (i.e. the behavior mode of the user is more likely to be continuously in a stable state), so that the online playing strategy is not suitable to be adjusted greatly when the video is in the preheating stage; after the video is in the preheating stage, the online playing strategy is suitable to be adjusted to a larger extent.
Based on this, the application sets a preheating time threshold (as a critical value for the online playing strategy change) in advance to distinguish the preheating stage of the pre-playing video. More specifically, the method and the device start timing when the pre-playing video starts to be played, and the timing time is the continuous online playing time of the pre-playing video. Meanwhile, judging whether the continuous online playing time exceeds a preset preheating time threshold value; if not, indicating that the pre-played video is in the pre-heating stage, not performing large adjustment on the online playing strategy (step S3); if yes, it indicates that the pre-played video is in the pre-heating stage, then the online playing policy is adjusted to a larger extent (step S4).
Step S3: the buffer threshold is incremented at a first growth rate to enable control of the periodic downloading of the video segments of the pre-play video by the incremented buffer threshold.
Specifically, the method sets a first low increasing speed in advance, and when the pre-played video is in the preheating stage, the method slowly increases the buffer threshold at the first increasing speed. The buffer threshold is slowly increased to realize the merging and downloading of the video segments at a slower speed, so that the energy consumption of the tail part of RRC (Radio Resource Control) is reduced by merging and downloading the video segments to achieve the aim of saving the energy of the battery.
More specifically, the main functions of RRC include establishment and release of radio resource connection, broadcast function of system information, radio access point establishment, reconfiguration and release. In a terminal device network, the establishment and release of radio frequency resource connection may affect the energy consumption of the terminal device accessing the network. And RRC tail energy consumption: when the video segment is downloaded each time, a video segment downloading session is started, and after the video segment downloading session completes downloading the video segment, the terminal equipment maintains a high-energy-consumption state for a period of time, and then enters a low-energy-consumption state. The high energy consumption of the no-download state caused by the part is the RRC tail energy consumption.
By increasing the buffer threshold (which means that more video segments will be downloaded in one merge at a time in each subsequent video segment download session), the merged video segment download session achieves a more efficient power consumption mode, and the unnecessary RRC tail energy after each video segment download session is naturally reduced after merging.
Step S4: increasing the buffer threshold at a second increase speed until the buffer threshold reaches a preset buffer extreme value, so as to realize that the periodical downloading of the video segment of the pre-playing video is controlled through the increased buffer threshold; wherein the first growth rate is less than the second growth rate.
Specifically, the method sets a higher second growth speed in advance, and when the pre-played video is after the pre-heating stage, the method increases the buffer threshold value at the second growth speed quickly until the buffer threshold value is increased to a preset buffer extreme value. The buffer threshold is rapidly increased, so that the video segments are merged and downloaded at a higher speed, and the energy consumption of the RRC tail part is reduced by merging and downloading the video segments, so that the aim of saving energy of the battery is fulfilled.
It can be seen that the present application uses an "incremental" strategy to adjust the buffer threshold, and analyzes and evaluates the current behavior pattern of the user through the continuous online playing time, so as to schedule online video playing by adopting different optimization strategies according to different behavior patterns of the user. That is, a unified framework is provided for different behavior patterns of the user through the mechanism, and the aim of self-adjusting and optimizing the battery energy consumption is achieved by dynamically and flexibly merging the video segment downloading sessions.
The invention provides a self-adjusting playing method of an online video, which comprises the following steps: after receiving an online video playing request, filling a group of video segments of a pre-played video into a preset buffer area, and controlling the periodic downloading of the video segments of the pre-played video through a preset buffer threshold value; wherein the buffer threshold value represents the number of the one-time merging downloading video segments; starting playing the pre-played video after the video segment is filled, counting the continuous online playing time of the pre-played video in real time, and judging whether the continuous online playing time exceeds a preset preheating time threshold value; if not, increasing the buffer threshold value at a first increasing speed; if so, increasing the buffer threshold value at a second increasing speed until the buffer threshold value reaches a preset buffer extreme value, so as to realize the control of the periodic downloading of the video segment of the pre-playing video through the increased buffer threshold value; wherein the first growth rate is less than the second growth rate.
Therefore, the method and the device consider that the behavior mode of the user is extremely unstable in the initial stage of video playing; and as the continuous online playing time of the video increases, the behavior mode of the user gradually tends to be stable. Therefore, the initial value of the buffer threshold is set to be low, the buffer threshold is slowly increased at the initial stage of video playing, and the buffer threshold is rapidly increased after the continuous online playing time of the video reaches a certain value, so that the purpose of self-adjusting and optimizing the energy consumption of the battery is achieved by dynamically adjusting the buffer threshold, and the waste situation of network bandwidth is reduced to a certain extent when the user behavior is unstable.
On the basis of the above-described embodiment:
as an optional embodiment, the self-adjusting playing method further includes:
and (4) solving the residual capacity of the buffer area in real time, and expanding the total capacity of the buffer area when the residual capacity is smaller than a preset capacity threshold value until the total capacity reaches a preset capacity extreme value.
Further, typically, the greater the total capacity of the buffer, the greater the number of video segments that are allowed to be downloaded during the buffer pre-fetch phase, and thus, the number of subsequent video segment download sessions during the buffer maintenance phase will be reduced. It is known that the buffer pre-fetching phase can generally achieve a higher network download speed than the buffer maintenance phase, thereby saving the time consumed for data download, so that a larger buffer capacity can save energy consumption on the terminal device. However, the behavior mode of the user is neglected in a pure buffer expansion optimization manner, and if the behavior of the user is in an unstable mode, a large number of cached video segments are usually cleared, and the cleared video segments are not played at the client, so that a serious problem of network bandwidth waste is caused, and extra battery energy consumption is consumed.
It can be seen that a larger buffer capacity is advantageous for reducing the power consumption of the terminal device when the behavior pattern of the user is in a steady state. And in the unstable state of the behavior mode of the user, the smaller buffer capacity is beneficial to reducing the power consumption of the terminal equipment.
Based on this, the present application also sets the buffer capacity as an adjustable parameter and sets a smaller initial value for the buffer capacity in advance. It should be noted that, during the period when the buffer threshold is slowly increased, the initial capacity of the buffer is sufficient for downloading the video segment. In the phase of a rapid increase in the buffer threshold, there may be insufficient initial capacity of the buffer. Therefore, at the stage of increasing the buffer threshold, the method and the device solve the residual capacity of the buffer area in real time, compare the residual capacity of the buffer area with the preset capacity threshold, and expand the total capacity of the buffer area when the residual capacity of the buffer area is smaller than the preset capacity threshold. After the buffer zone is expanded, the residual capacity of the buffer zone is still obtained in real time, when the residual capacity of the buffer zone is smaller than a preset capacity threshold value, the total capacity of the buffer zone is expanded again (the capacity value of each expansion can be set in advance), and the total capacity of the buffer zone is stopped being expanded until the total capacity of the buffer zone reaches a preset capacity extreme value.
Therefore, the dynamic adjustment of the capacity of the buffer area is realized in the video playing process, and the purpose of optimizing the battery energy consumption by using different buffer area capacities according to different behavior modes of a user is achieved.
As an optional embodiment, after the playing of the pre-play video is started, the self-adjusting playing method further includes:
the played video segment is purged from the buffer.
Further, in the process of playing the pre-played video, the played video segment is cleared from the buffer area, so that sufficient storage space is provided for the subsequent video segment.
As an optional embodiment, the self-adjusting playing method further includes:
and after receiving a closing request of the pre-played video, closing the pre-played video, clearing the buffer area, and initializing all playing parameters.
Further, according to the method and the device, after a closing request of the pre-played video is received, the pre-played video is immediately closed, meanwhile, the buffer area is cleared, and all playing parameters (including the buffer threshold value and the buffer area capacity) are initialized to prepare for receiving a new online video playing request.
As an optional embodiment, the self-adjusting playing method further includes:
and after the pre-played video is played, clearing the buffer zone and initializing all playing parameters.
Further, the method and the device clear the buffer area after the pre-played video is played, and initialize all the playing parameters to prepare for receiving a new online video playing request.
As an optional embodiment, the self-adjusting playing method further includes:
and after a jump request of the pre-played video is received, clearing the buffer area, initializing all playing parameters, and re-executing the step of filling a group of video segments of the pre-played video into the preset buffer area so as to continuously play the pre-played video at the jump position.
Further, after a skip request (corresponding to a skip position of the pre-played video) of the pre-played video is received, the buffer area is immediately cleared, all playing parameters are initialized, and meanwhile, a step of filling a group of video segments of the pre-played video into the preset buffer area is executed again (the unplayed video after the skip position is taken as the current pre-played video), so that the pre-played video is continuously played at the skip position.
