The inventor of the present invention has studied and found that, even if a user has a video modification right, since the user cannot usually predict the subsequent (for example, next second) content of the video, it cannot be determined in advance which video segments are dragged and need to be skipped, and it cannot be determined in advance which video segments are splendid and need to be carefully tasted, and usually the entire video can be watched only according to the video duration, which results in low video playing efficiency, and limits the requirement of the user for watching more video in a fixed time period, which results in low video watching efficiency of the user.
Even if the user can accelerate or decelerate the playing speed of the video by fast forward or fast backward; however, the user operation is required to be tedious first; secondly, as the user cannot predict the subsequent content of the video, the positioning accuracy of fast forward and fast backward is low, the user is often required to pay a lot of extra operations to occupy the time for the user to watch the video, the requirement for the user to watch the video for more time in a fixed time period is still limited, and the efficiency for the user to watch the video is low.
In the embodiment of the invention, each video is divided into video clips of a plurality of time intervals in advance, and a playing speed is set for each time interval to form playing speed description information; when a video is played, acquiring a plurality of play speed description information respectively associated with a plurality of time intervals of the video; and playing the video clip corresponding to each time interval according to the acquired playing speed description information associated with each time interval. Therefore, by using the embodiment of the invention, the video clip corresponding to the associated time interval can be played according to the acquired play speed description information without extra operation of the user. Through carrying out reasonable setting to the broadcast speed description information of different time intervals, for example set up the broadcast speed description information of the time interval of comparatively draging the plot of the head song, the tail song, and the plot of video to the standard broadcast speed after accelerating, under the condition that does not influence the user and watches comparatively splendid or the video clip that a plurality of users generally are comparatively interested in, can shorten the actual broadcast duration of every video, thereby can play more videos in same period, promote the video broadcast efficiency of video server greatly, promote user's video viewing efficiency greatly.
The technical solution of the embodiments of the present invention is specifically described below with reference to the accompanying drawings.
In the embodiment of the invention, the video provided by the video service party can be played on line for the user to watch. For example, a user obtains video data online through a web browser or a video player, and plays the video.
Preferably, the video provided by the video service party can be played on the following occasions: vehicles (e.g., subways, buses, trains, taxis, or airplanes, etc.), building structures (e.g., waiting halls, bank halls, or office buildings, etc.), public facilities (e.g., billboards, or promotional windows, etc.).
In the embodiment of the invention, video clips corresponding to a plurality of time intervals can be divided from each video. For example, for a video of one entertainment program, a plurality of video segments of a beginning piece, a main content, a special guest stadium, a guest performance, and an ending piece may be chronologically divided from the video. The several video segments have respective time intervals, for example, when the playing time of the video is 53 minutes, the time intervals of the leader song, the main content, the special guest stadium, the guest performance, and the trailer song of the video may be respectively the 4 th second to the 1 st zeroth 6 second, the 1 st zeroth 6 second to the 40 th minute 0 second, the 40 th minute 0 second to the 45 th minute 0 second, the 45 th minute 0 second to the 50 th minute 0 second, and the 50 th minute 0 second to the 53 th minute 0 second of the playing time of the video.
In the embodiment of the present invention, a plurality of methods may be employed to determine a plurality of play speed description information associated with a plurality of time intervals of a video, respectively.
The first method for determining play speed description information associated with a time interval comprises the following steps: and determining the playing speed description information associated with each time interval of the video according to the recommendation information of the video service party.
It is easy to understand that the video service party usually needs to examine the video to be watched by the user in advance according to the regulations of relevant departments; or the video itself is made by the video service side; therefore, the video service side is very familiar with the content of the video, and can easily distinguish video clips of different time intervals in the video.
The video service party can determine the appropriate playing speed of the video clip of each time interval of each video according to historical data, empirical data, experimental data, and/or actual conditions, and generate playing speed description information according to the appropriate playing speed as the playing speed description information associated with the time interval.
Wherein the playback speed description information may be at least one of: absolute play speed, standard play speed, and multiples thereof. For example, the absolute play speed may be 22, 24, 25, or 30 frames/second, etc.; the standard playback speed may be 24 frames/second, and the multiple of the standard playback speed may be × 0.9, × 1, × 1.2(1.2 represents a multiple, and × 1.2 represents a 1.2-times speed of the standard playback speed), × 2.5, or × 10, and so on.
Further, research shows that the user does not perceive the playing speed not higher than x 1.2 obviously; that is, it is difficult for the user to partition whether the video is played at the standard play speed or at × 1.2 times the standard play speed with respect to the same video.
Preferably, after the playing speed description information associated with each time interval of the video is determined by the first method, the playing speed description information file of the video is generated according to a plurality of playing speed description information associated with a plurality of time intervals of the video respectively.
Specifically, a play speed description information file is created for each video, and the play speed description information file includes a plurality of pieces of description information. Each piece of description information includes: number of description information, time interval (start time and end time) of a video clip, and play speed description information of the time interval; preferably, each piece of description information may further include: the content of the video segment of the time interval is described.
For example, fig. 2 shows an example of a play speed description information file. The play-speed description information file shown in fig. 2 includes five pieces of description information numbered 1-5. The time interval of the first piece of description information is 4 seconds 299 milliseconds to 1 minute zero 6 seconds 290 milliseconds, the playing speed description information of the time interval is multiplied by 2.5 (namely 2.5 times of the standard playing speed), and the description information of the video clip corresponding to the time interval is 'head song, which can be multiplied by 2.5 times'. The details of the second to fifth pieces of description information are similar and are not repeated.
Further, in the embodiment of the present invention, the playback speed description information of the entire video may be determined according to the level and/or category of the content of the video. Preferably, the playing speed description information of the whole video is determined according to the difficulty level and/or the category of the content of the video.
For example, the present inventors have found that as the standard of living increases, more and more people begin to pay attention to diet adjustment, exercise, and exercise. Therefore, the scientific, methodical and experienced fitness video is very popular with users. The main exercise methods of the users are usually practice following the movements in the video. The traditional body-building video respectively prepares a plurality of corresponding body-building videos according to a plurality of difficulty levels, such as body-building videos of entry, low order, middle order, high order and breakthrough limit levels; the difference of action frequency and rest interval between actions exists among the fitness videos with different difficulty levels. However, the same exercise content requires the production and storage of exercise videos with multiple difficulty levels, which greatly increases the production and maintenance costs of the videos.
By utilizing the technical scheme of the embodiment of the invention, only one body-building video is required to be produced and stored for the same body-building content. Then, a plurality of pieces of playing speed description information are respectively configured for a plurality of difficulty levels of the fitness video. For example, the play speed description information of the fitness video of the entry, low, middle, high, and breakthrough limit levels may be configured as × 0.9, × 1, × 1.1, × 1.2, and × 1.3, respectively, etc. The storage space occupied by the playing speed description information is KB (kilobyte), which is far less than the storage space occupied by the video, and the manufacturing and maintenance cost of the video is greatly reduced.
Further, in the embodiment of the present invention, the playing speed description information of the video is determined according to the preset playing time period of the video.
For example, the inventor of the present invention found that the office worker is short in time, and is very short in time when staying relaxed in the evening towards nine-fifths of a night, so there is gold book saying that 20 to 22 points per day is the peak time when the user watches the video.
By using the technical scheme of the embodiment of the invention, the playing speed description information of all videos in the preset playing time segment within the peak time period can be set as the accelerated standard playing speed, for example, the standard playing speed is 1.1-1.2 times. And subsequently, the videos are played according to the accelerated standard playing speed, so that the video content of 2.2-2.4 hours can be played within 2 hours, and the user has no obvious feeling of accelerating the videos. Therefore, the playing quantity and efficiency of the videos in the same time period are increased under the condition that the user experience of watching the videos is not influenced.
The second method for determining the playing speed description information associated with the time interval comprises the following steps: and determining playing speed description information associated with each time interval of the video according to the operation of a plurality of users on the video.
A flowchart of a method for determining play speed description information associated with each time interval of a video according to operations of a plurality of users on the video is shown in fig. 1a, and includes the following steps:
s101: and collecting the operation of a plurality of users for each time interval of the video, and determining the habitual operation of the plurality of users for each time interval.
For each video, the operation of multiple users for each time interval of the video may be captured.
And according to the operation of the plurality of users for each time region of the video, determining the habitual operation of the plurality of users for the time region.
For example, a plurality of users take four operations for one time region of a video, and the number of users selecting each operation is different; the operation with the largest number of users can be used as the habitual operation of the plurality of users for the time zone.
S102: according to the habitual operation aiming at each time zone, the playing speed description information related to the time interval of the video is determined.
Habitual operations of a plurality of users for a time zone are various; for example, play, fast forward, skip, pause, rewind, and/or repeat play, etc.
When the habitual operation for a time zone is playing, the playing speed description information associated with the time zone is determined to be the standard playing speed.
When the habitual operation for a time zone is fast forward or skip, the playing speed description information associated with the time zone is determined as the standard playing speed after acceleration. For example, the standard playback speed is 1.2 times faster as indicated by x 1.2.
When the habitual operation for a time zone is pause, rewind and/or repeat play, the play speed description information associated with the time zone is determined to be the standard play speed after slowing down. For example, the standard playback speed indicated by x 0.9 is slowed down to 0.9 times the speed.
Preferably, when there is no habitual operation for a time zone, the playing speed description information associated with the time zone is determined according to the recommendation information of the video service party and/or the content of the video segment corresponding to the time zone.
Further, for a certain video, there is no user operation on the video, and naturally there is no habitual operation on the time region of the video. At this time, the playing speed description information associated with the time interval may be determined according to the recommendation information of the video service provider and/or the content of the video segment corresponding to the time zone. For example, the playback speed description information associated with the time region of the beginning of a movie of the video is set to a standard playback speed of × 10 times.
Preferably, as shown in fig. 1b, a flowchart of another method for determining play speed description information associated with each time interval of a video according to operations of multiple users on the video further includes the following steps based on the steps S101 to S102:

The second piece of description information in fig. 2 has a time interval of 290 milliseconds at 1 minute-zero 6 seconds to zero milliseconds at 40 minutes-zero seconds, the playback speed description information of the time interval is x 1.2 (i.e. 1.2 times the standard playback speed), and the description information of the video segment corresponding to the time interval is "dishonest do not disturb the subject content".
The time interval of the third piece of description information in fig. 2 is from 40 minutes zero seconds to 45 minutes zero seconds zero milliseconds, the playback speed description information of the time interval is × 1 (i.e., the standard playback speed), and the description information of the video segment corresponding to the time interval is "special guest, yellow dawn arena".
The fourth piece of description information in fig. 2 has a time interval from zero millisecond of 45 minutes to zero millisecond of 50 minutes, the playing speed description information of the time interval is × 0.9 (i.e. 0.9 times of the standard playing speed), and the description information of the video segment corresponding to the time interval is "guest live performance magic".
The time interval of the fifth piece of description information in fig. 2 is 50 minutes zero seconds and zero milliseconds to 53 minutes zero seconds and zero milliseconds, the playing speed description information of the time interval is x 10 (i.e. 10 times of the standard playing speed), and the description information of the video segment corresponding to the time interval is "trailer song, sponsor information".
A third method for determining play speed description information associated with a time interval includes: and determining the playing speed description information associated with each time interval of the video according to the setting information of other users for the playing speed of the video.
