[ first embodiment ] A method for manufacturing a semiconductor device
As shown in fig. 1, a playlist editing method according to a first embodiment of the present invention is used to solve the problems of high complexity and low accuracy in manually calculating the number of media items and the playing times by a user, and improve the efficiency of playlist editing. The playlist editing method, for example, includes the steps of:
s20, obtaining the playing duration of each media item in the playing backup, wherein the playing backup comprises at least one media item;
s30, acquiring the total duration and the current duration of the playlist;
s40, obtaining the remaining duration of the first playlist according to the total duration and the current duration of the playlist;
s50, determining the alternate playing times of each media item according to the remaining time length of the first playing list and the playing time length of each media item in the spare piece.
Step S40 is specifically to perform subtraction operation on the total duration and the current duration of the playlist to obtain the remaining duration of the first playlist; step 50, specifically, obtaining the playing duration of the spare video according to the playing duration of each media item; dividing the remaining duration of the first playlist and the duration of the spare playing to obtain the number of playing candidates of the media item in the spare; step S50 may also be a step of obtaining the spare playing time of the spare according to the playing time of each media item; dividing the remaining duration of the first playlist and the playing duration of the spare film to obtain a first alternate playing time and a remaining duration of a second playlist of the media item in the spare film; selecting a target spare media item with the residual time length of the second play list in each media item in the spare as a target spare media item; and obtaining a second alternate playing time of the target spare media item according to the remaining duration of the second playlist and the playing duration of the target spare media item, and taking the sum of the first alternate playing time and the second alternate playing time of the target spare media item as the alternate playing time of the target spare media item.
The playlist editing method provided by the present embodiment may be implemented, for example, by software installed on a computer, such as a web browser. In order to facilitate a clearer understanding of the present embodiment, a web browser is taken as an example, and a playlist editing method of the present embodiment is described in detail below with reference to fig. 1.
Specifically, when an operator edits the playlist, for example, the operator acquires the playlist editing page through a browser, and the user sets the total duration of the playlist on the playlist editing page to 120 minutes, where the total duration of the playlist is the total duration that the user needs to play the playlist, and the total duration can be set by himself or herself as needed, and the user adds a media item a, a media item b, a media item c, a media item d, and a media item e in the playlist, sets the play times of each media item, and obtains the current duration of the playlist to 100 minutes, where the current duration of the playlist is the total duration that the media item added currently in the playlist and the play times of the media items can be played. For example, the user selects the media item d and the media item e as the backup, for example, the playing duration of the media item d is 10 seconds, and the playing duration of the media item e is 3 seconds, and the specific selection manner is, for example, that the user obtains the free duration according to the total duration and the current duration of the playlist, and selects the media item as the backup by checking the media item according to the free duration, or selects the media item in other places such as a media library as the backup, which is not limited in this disclosure. The webpage browser responds to the operation instruction selected by the user to determine that the media d and the media item e are spare pieces; for example, the playing duration of each media item in the playing back is automatically obtained, where the playing back includes at least one media item, that is, the playing durations of the media item d and the media item e are obtained; automatically acquiring the total duration of the playlist of 120 minutes and the current duration of the playlist of 100 minutes; obtaining a remaining time length of a first playlist according to the obtained total time length of the playlist of 120 minutes and the current duration of the playlist of 100 minutes, specifically, for example, subtracting the total time length of the playlist and the current duration of the playlist to obtain the remaining time length of the first playlist, that is, subtracting the total time length of the playlist of 120 minutes and the current duration of the playlist of 100 minutes to obtain the remaining time length of the first playlist of 20 minutes, that is, 1200 seconds; of course, other operations may be performed herein, and the invention is not limited thereto. And determining the alternate playing times of each media item in the backup according to the remaining time of the first playlist of 1200 seconds, the playing time of each media item in the backup, namely the playing time of the media item d of 10 seconds and the playing time of the media item e of 3 seconds. Specifically, the spare playing time of the spare is obtained to be 13 seconds according to the playing time of the media item d being 10 seconds and the playing time of the media item e being 3 seconds; dividing the remaining duration of the first playlist of 1200 seconds and the remaining duration of the spare film of 13 seconds, for example, to obtain 92 first alternate playing times of the media item in the spare film and 4 second remaining duration of the second playlist, and dividing the obtained quotient as the first alternate playing times and the remainder as the remaining duration of the second playlist; when the remainder obtained by dividing the remaining duration of the first playlist and the playing duration of the spare disc is zero, the obtained quotient, namely the first alternate playing time, is used as the alternate playing time of the media item in the spare disc; and when the remainder is greater than zero, taking the remainder as the remaining duration of a second playlist, and selecting a target spare media item in each media item in the spare as a target spare media item, wherein the target spare media item is the remaining duration of the second playlist. Specifically, for example, a time difference is obtained by subtracting the remaining time length of the second playlist from the playing time length of each media item, for example, a time difference of the media item d is 6 seconds by subtracting the remaining time length of the second playlist of 4 seconds from the playing time length of the media item d of 10 seconds, and a time difference of the media item e is 1 second by subtracting the remaining time length of the second playlist of 4 seconds from the playing time length of the media item e of 3 seconds; comparing the two time length differences to obtain the media item with a smaller time length difference, for example, comparing the time length difference of the media item d being 6 seconds with the time length difference of the media item e being 1 second, and determining the media item with the smaller time length difference as the target spare media item e; and obtaining the second alternate playing time of the target spare media item as 1 time according to the remaining time length of the second playlist of 4 seconds and the playing time length of the target spare media item, namely the playing time length of the media item e of 3 seconds, and taking the sum of the first alternate playing time of the target spare media item of 92 times and the second alternate playing time of 1 time as the alternate playing time of the target spare media item, namely the media item e of 93 times. And then, circularly executing the operations until the remaining time of the playlist cannot finish the playing of the media item with the minimum playing time, and finishing the execution to obtain a spare piece result: the number of playback candidates for media item d is 92, and the number of playback candidates for media item e is 93.
In a specific implementation manner of this embodiment, the playing order of the media items of the playlist is adjusted. For example, the playing order of the media items of the playlist is adjusted in response to a user dragging and moving operation, which is not limited by the invention.
In summary, the present invention obtains the playing duration, the total duration and the current duration of each media item in the backup by determining the media item as the backup, and determines the alternate playing times of the media items according to the playing duration, the total duration and the current duration of each media item, i.e. automatically calculating the playing times of the backup is realized, and the problems of high complexity and low accuracy in manually calculating the number and playing times of the media items by a user are solved, thereby greatly improving the efficiency of editing the playing list. In addition, the playing sequence of the media items of the playing list is adjusted by responding to the user operation instruction, so that the adjustment of the playing sequence of the spare media items is realized, the user can adjust the playing sequence of the media items at will according to the requirement, and the user experience is greatly improved.
