[ first embodiment ] A method for manufacturing a semiconductor device
Referring to fig. 1, a media playing control method according to a first embodiment of the present invention includes the following steps:
s11: determining a target playing progress of a program according to the time of a terminal system, wherein the target playing progress changes along with the time change of the terminal system;
s13: executing skip playing operation according to the target playing progress so as to play the program;
s15: after the skip playing operation, detecting whether a difference value between the actual playing progress and the target playing progress of the program meets a preset requirement;
s17: responding to the difference value not meeting the preset requirement, and determining the jumping target progress according to the actual playing progress, the difference value and the progress correction value;
s19: and jumping to a key frame matched with the jumping target progress to play the program according to the jumping target progress.
In this embodiment, when it is detected that a difference value between an actual playing progress and a target playing progress does not meet a preset requirement, a jump target progress is determined according to the actual playing progress, the difference value and a progress correction value, and then, according to the jump target progress, a program is played by jumping to a key frame matched with the jump target progress, for example, the program is played by jumping to a key frame closest to the jump target progress; therefore, the playing synchronization can be accelerated, and the quick playing synchronization can be realized.
Referring to fig. 2, optionally, in a specific embodiment, the step S11 includes the following sub-steps:
s111: searching operation is carried out in a program list according to the terminal system time so as to obtain the program;
s113: and calculating the difference between the terminal system time and the starting playing time of the program as the target playing progress.
In the embodiment, the program to be played at the current terminal system time point can be acquired by combining the terminal system time with the program list, and then the progress position of the program to be played at the current terminal system time point, that is, the target playing progress, can be calculated according to the acquired starting playing time of the program. It should be noted that the program list includes one or more programs, a single program may be a video, a text or other media, and each program typically has parameters such as a start playing time, an end playing time (or a playing duration).
Optionally, in a specific embodiment, the progress correction value includes a preset command response time consumption value and a preset key frame distribution related correction value. The embodiment presets the composition of the progress correction value and gives a default value, so that the calculation complexity of the progress correction value can be simplified, and system resources can be saved. Of course, in other embodiments, the progress correction value may only include the command response time consumption value, and does not include the key frame distribution related correction value, which may also be better than the prior art to achieve the synchronization of the playing progress quickly to some extent.

s21: and when detecting that the difference value between the actual playing progress and the target playing progress of the program meets the preset requirement, outputting a display control instruction to control the carried display screen to be switched from a black screen state to a program display state.
The terminal of the embodiment keeps the loaded display screen in the black screen state before the playing progress synchronization is achieved, so that the user does not sense the whole progress synchronization process, and the user experience is improved.
In order to more clearly understand the media playing control method of the present embodiment, the following takes the program as an example, and the detailed description is made with reference to a specific example.
Specifically, for the problem of play synchronization of the media play control terminal after the video program is restarted, the playing progress is adjusted by an algorithm on the basis of a player suitable for being installed on the media play control terminal to complete the play synchronization after the restart. In order to ensure the synchronicity after the terminal is restarted, it is necessary to ensure that the system time after the terminal is restarted is consistent with the system time of other synchronous playing terminals, and the synchronicity of time may adopt the existing mature time synchronization scheme, which is not described herein again. Under the condition that the system time is taken as a reference standard for synchronous playing, the synchronization can be realized only by adjusting the video playing progress to the position where the video should be played at the moment. Because the video playing jump can only jump to the key frame, the jump of the video needs time consumption and the time consumption may not be fixed, the terminal jumps of different models may have different time consumption, and the number of the key frames and the distribution difference of different video resources may be larger, and other influencing factors, when the player jumps, the playing progress is either slow or fast after the player jumps, and the probability of one-time jumping progress synchronization is lower; in fact, the playing synchronization does not need to be completely accurate, human eyes can distinguish the difference between the video schedules when the difference is lower than 24 frames per second, namely the error is within 40ms, the requirement of synchronous playing can be basically met, and the requirement of synchronous playing of the playing schedule can be met by considering that the playing schedule is possibly slow or fast, so the playing schedule can be achieved by locking the target within +/-20 ms.
In light of the above, the media playing control method of this example, for example, adopts the following steps to implement the synchronization of the playing progress.
(a) Firstly, after the terminal is restarted, calculating the progress that the video program should be played, namely the target playing progress, after entering the video program synchronous playing flow (step S11), specifically, subtracting the starting playing time of the video program from the terminal system time to obtain the target playing progress; then, a skip play operation is performed based on the target play progress to play the video program (step S13).
(b) A task thread is created to detect the difference between the actual playing progress and the progress that the simulcast should actually play, which thread is started when the player starts playing and needs to jump to the progress. Based on empirical values derived from experimental data, the thread is set to perform a test every 10 milliseconds, for example. During detection, the current actual playing progress and the target playing progress of the player are obtained and compared (step S15), and if the error (i.e., the difference value Δ t) is less than 10 ms (it is worth mentioning that the error is within 20ms, the requirement can be met, and for better visual effect, the error is further controlled within 10 ms in this example), the detection task is ended. Otherwise, if the time is greater than 10 ms, the subsequent skip play process is entered, i.e. the aforementioned steps S17 and S19 are executed. Before the jump playing flow is finished, the detection task is ignored until the detection is finished, and the next detection is not carried out.
(c) The task thread can help to adjust the playing progress to the expected playing progress on a certain time node as long as the task thread is executed, so that the synchronous playing after the video is restarted is realized. Of course, it may not be sufficient to do this only, but many hops may be required to complete, although synchronization may eventually be guaranteed. This adjustment time cannot be guaranteed, and may only take a fraction of a second or several minutes, even if the program is played over and without synchronization. Therefore, how to efficiently and quickly complete the progress jump becomes the key point of the media play control scheme in this example.
(d) In order to complete jump synchronization as fast as possible, the inventor of the present application has collected instruction response time-consuming values of a large number of media playing terminals, such as time t2 taken by a video program from the start of jump instruction issuance to the completion of jump, by executing a program playing jump function in batch. At the jump, the jump step is designed to be added to t2 on the basis of the time Δ t to be jumped, which greatly increases the probability of reaching the desired point in time directly after a jump. In addition, in order to further increase the probability that one jump reaches a desired time point (or a desired progress), in this example, a key frame distribution related correction value t3 is added according to the key frame distribution condition of a general video, and the jump step size is designed to be calculated by Δ t + t2+ t3 at each jump, so that the design greatly improves the success rate of the video jumping to the target progress.
(e) The key frame distribution of video can mostly guarantee 1 to 2 key frames per second. With such a video resource, the algorithm can jump to the target progress position quickly. However, for a very small number of resources with a small number of partial key frames, the progress synchronization time may become uncontrollable. Thus, this example devised two solutions to the problem: the first scheme is that basic information of a video program is read, if key frames of the video are distributed less than 1 frame per second, frame interpolation processing is carried out on the video, some non-key frames of the video program are modified into key frames, and the original video is replaced by the processed video; in the second scheme, a front-end device of the media playing and controlling terminal, such as an upper computer, reads video information, stores key frame time information in a file, and sends the file to the media playing and controlling terminal along with a program (certainly, key frame time information may also be generated locally by the media playing and controlling terminal), and when the playing progress of the media playing and controlling terminal jumps, the key frame distribution related correction value t3 is adjusted by obtaining the key frame time closest to the jumping target progress (step S163).
(f) In addition, the display screen carried by the media playing and controlling terminal is kept in a black screen state in the whole progress synchronization period, and the screen is opened only after the progress synchronization, namely, the program display state is entered (step S21), and the user does not feel in the whole process.
