[ first embodiment ] A method for manufacturing a semiconductor device
Referring to fig. 1, a program playing method according to a first embodiment of the present invention is shown. The program playing method includes, for example:
s10, responding to the synchronous playing command, acquiring network time and updating the system time of the local computer based on the network time;
s11, determining a target playing page of the current playing program and a target playing position of the target playing page according to a preset playing rule, the system time of the local computer and the page playing time length of each page of the current playing program; and
and S12, starting to play the target playing page from the target playing position.
For the convenience of understanding the present invention, the following describes the program playing method according to the embodiment of the present invention in detail with reference to fig. 1 to 5. The program playing method of the embodiment of the present invention may be executed by program playing software running on a terminal 22 (as shown in fig. 5) of a playing system, for example, and the playing system further includes an upper computer 21, where the upper computer 21 is, for example, a program editing and publishing terminal. The specific implementation is as follows.
First, the upper computer 21 (specifically, program editing and publishing software installed on the upper computer 21) sends a synchronous play command to the terminal 22.
Then, the terminal 22 acquires the network time in response to the synchronized play command, and updates the local system time based on the network time. Specifically, the process of acquiring the network time may be, for example, the terminal 22 sends a time acquisition request to a network time server, and the network time server returns the network time to the terminal 22. Then, the terminal 22 updates the local system time to the network time.
And then, the terminal determines a target playing page of the current playing program and a target playing position of the target playing page according to a preset playing rule, the system time of the terminal and the page playing time of each page of the current playing program. For example, the preset playing rule may be that the reference playing time of the first page in the currently played program is 12:00 a day early morning (that is, the currently played program starts to be played circularly from the first page from 12:00 a morning and the pages included in the currently played program are played sequentially), the currently played program may include one or more pages, and when the currently played program has only one page, the preset playing rule is that the reference playing time of the page is 12:00 a day early morning, a specific preset playing rule may be customized by a user, and an embodiment of the present invention is not specifically limited herein.
As shown in fig. 2, S11 specifically includes: s110, determining the playing start time of each page before the system time of the local machine according to the preset playing rule and the page playing duration of each page; s112, determining a page corresponding to the latest playing starting time closest to the system time of the local machine in the playing starting time as the target playing page; s114, determining the played time length of the target playing page according to the latest playing starting time and the system time of the local player; and S116, determining the playing position of the target playing page corresponding to the played time length as the target playing position.
Specifically, the description will be given by taking an example in which the network time (i.e., the local system time) is 1:00 a.m., the preset playing rule is that the reference playing time of the first page in the currently played program is 12:00 a.m., the currently played program includes three pages, the page playing time of the first page is 10 minutes, the page playing time of the second page is 20 minutes, and the page playing time of the third page is 15 minutes. In step S110, determining the playing start time of each page before the system time of the local computer according to the preset playing rule and the page playing time of each page, that is, performing time accumulation calculation from the reference playing time, that is, beginning to play the first page at 12:00 am, beginning to play the second page at 12:10 am (the page playing time of the first page is 10 minutes), beginning to play the third page at 12:30 am (the page playing time of the second page is 20 minutes), beginning to play the first page at 12:45 am (the page playing time of the third page is 15 minutes), and beginning to play the second page at 12:55 am (the page playing time of the first page is 10 minutes); in step S112, determining a page corresponding to the latest playing start time closest to the local system time of 1:00 in the morning, that is, 12:55 in the morning, that is, the second page, as the target playing page; in step S114, determining the played time length of the target playing page, i.e. 5 minutes, according to the latest playing start time, i.e. 12:55 in the morning, and the local system time, i.e. 1:00 in the morning; and S116, determining the playing position of the target playing page corresponding to the played time length as the target playing position, namely the position corresponding to the 5 th minute of the second page. Of course, the specific process of determining the target playing page and the target playing position is not particularly limited in the embodiments of the present invention, as long as the target playing page of the currently playing program and the target playing position of the target playing page can be determined according to the preset playing rule, the system time of the local computer, and the page playing duration of each page of the currently playing program.
Then, the terminal 22 starts to play the target playing page from the target playing position, and in the above example, the terminal 22 starts to play the media to be played corresponding to the second page from the 5 th minute of the second page.
In the technical scheme, the target playing page is played from the target playing position by determining the target playing page and the target playing position corresponding to the system time of the local terminal, so that the plurality of terminals play programs based on the same reference time, the terminals can play the programs synchronously, and the watching experience of audiences is improved.
According to the above, the target playing page comprises at least one media; as shown in fig. 3, after the terminal 22 starts playing the target play page from the target play position, the terminal 22 determines whether the type of the target media in the at least one media is a video (corresponding to step S13 of fig. 3); and in response to a target media of the at least one media being a video, periodically correcting a playing progress of the target media (corresponding to step S14 of fig. 3). Specifically, the type of the media may be video, picture, text, and the like, and the embodiments of the present invention are not limited thereto. The terminal 22 periodically corrects the playing progress of the media of which the type is video in the at least one media, so as to further realize the synchronous playing of the target playing program.
As mentioned above, as shown in fig. 3, the periodically correcting the playing progress of the target media specifically includes:
s142, the terminal 22 obtains the current system time of the local computer, the total image frame number of the target media and the current playing image frame number of the target media; here, since the local system time has been updated in step S10 of fig. 1, the current local system time acquired here is an accurate time, and the current local system time is a time corresponding to the time at which the periodic correction is performed. And the total image frame number of the target media is the attribute of the target media. The current playing image frame number of the target media, that is, the image frame number played in a time period from the latest playing start time, that is, early morning 12:55, to the current local system time, is usually automatically generated and stored when the media starts to be played, and here, the terminal 22 may directly read the current local system time, the total image frame number of the target media, and the current image playing frame number of the target media.
S144, the terminal 22 plays the time according to the latest playing start time, the current local system time, the media playing time of the target media andthe total image frame number determines the number of the expected playing image frames of the target media; the expected playing image frame number is specifically
S146, in response to that the expected playing image frame number is greater than or less than the current playing image frame number, the terminal 22 corrects the playing progress of the target media, so that the current playing image frame number of the target media is the expected playing image frame number. For example, the expected playing image frame number is 200 frames, and the current playing image frame number is 180 frames, which may be caused by video playing pause, in order to implement program playing synchronization, the playing progress of the target media is corrected, so that the target media jumps to a position corresponding to the expected image playing image, and the current playing image frame number of the target media is the expected playing image frame number. Of course, it is also possible that the expected number of playing video frames is less than the current number of playing video frames, which may be caused by the terminal decoder decoding process causing the video to play too fast.
As shown in fig. 5, the program playing method further includes that the terminal 22 determines a target playing time of a next page of the target playing page according to the latest playing start time and the page playing time of the target playing page (corresponding to step S15 in fig. 5), taking the above example as an example, the latest playing start time is 12:55 am, the page playing time of the target playing program, i.e., the second program, is 20 minutes, and the target playing time of the next page, i.e., the third page, is 1:15 minutes in the morning; at the target play time, the next page is played (corresponding to step S16 of fig. 5), that is, the third page is played beginning at 1:15 minutes in the morning. In the scheme, the target playing time of the next page is determined, and the next page is played at the target playing time without considering whether the target playing page is played completely, so that the synchronous playing of the programs is ensured.
In summary, the program playing method according to the embodiment of the present invention obtains the network time by responding to the synchronous playing command, and updates the system time of the local computer based on the network time; determining a target playing page of the current playing program and a target playing position of the target playing page according to a preset playing rule, the system time of the local computer and the page playing time of each page of the current playing program; and starting to play the target playing page from the target playing position, so that each program playing terminal can play the corresponding target playing page according to a preset playing rule, thereby realizing the consistency of the played contents of each program playing terminal, realizing the synchronous playing of the programs and improving the watching experience of audiences.
