As shown in fig. 2, before step S104, step S103 is further included: and acquiring the parameter information of the at least one media included in the program to be previewed.
In S104, the next playing time is the next playing time of the media.
In order to facilitate understanding of the present embodiment, a program preview method of the present embodiment will be described in detail with reference to fig. 3A to 3F.
In an embodiment of the present invention, media included in a program to be previewed may include general media and small containers, where the general media represents media directly arranged in the program, for example, including: text, pictures, video, digital clocks, analog clocks, weather components, rich text weather components, calendar components, web pages. A capsule is a combination of general media in a program that has a predetermined play order, i.e., a capsule includes a plurality of general media that can be played in the predetermined play order. The small container may also be referred to as a media collection, that is, a media collection comprising a plurality of general media having a predetermined play order.
The program preview method according to the embodiment of the present invention may be implemented, for example, by software installed on a PC, such as program preview software, which is previewed, for example, based on a browser, as shown in fig. 3A, which shows a program preview software interface 201. Program preview software interface 201 has program editing interface 203 and preview button 202 thereon. In response to a user adding at least one media, the program preview software adds 4 media, such as media 1, media 2, media 3, and media 4, respectively, on the program editing interface 203, for illustrative purposes, only 4 media are shown herein, and in practical applications, the user may add any number of media on the interface editing interface 203 according to the program requirements, and the number of media added on the program editing interface is not specifically limited in this embodiment of the present invention. In addition, the added media may be from the PC or may be obtained from a server, which is not specifically limited herein.
In the process of executing the program preview method according to the embodiment of the present invention by the program preview software, first, the program preview software receives an instruction for previewing a program to be previewed, for example, an instruction corresponding to clicking the preview button 202 by a user, records the time for receiving the instruction as a first time, and then, the program preview software obtains parameter information of 4 media on a program editing interface, where the parameter information includes the type of the media and the playing duration of the media, and the type of the media is the general media or the small container described above. Fig. 3B-3F describe parameter information of media 1 to 4 and a process of initializing each media information according to the parameter information of each media, that is, determining information such as a next play time of each media. As shown in fig. 3B, the type of the medium 1 is a general medium, the play duration is 2s, and the initialization parameter value of the medium 1 can be determined according to the parameter information of the medium 1, such as the type of the medium 1 and the play duration, for example, the number of plays is determined to be 0, the play duration is 2s, and the next play time is 0s. As shown in fig. 3C, the type of the medium 2 is a general medium, the playing duration is 2s, and the initialization parameter value of the medium 2 can be determined according to the parameter information of the medium 2, for example, the playing frequency is 0, and the playing duration is2s, and the next playing time is 0s. As shown in fig. 3D, the type of the medium 3 is a general medium, the playing duration is 4s, and the initialization parameter value of the medium 3 can be determined according to the parameter information of the medium 3, for example, the playing time is 0, the playing duration is 4s, and the next playing time is 0s. As shown in fig. 3E, the type of media 4 is a small container (i.e., a media collection) that includes 3 general media, which are general media a, general media b, and general media c, respectively, in a predetermined play order. Correspondingly, the play duration of the general media a is 2s, the play duration of the general media b is 1s, and the play duration of the general media c is 3s. The initialization parameter value of the medium 4 (media collection) may be determined according to the parameter information of the medium 4, for example, it is determined that the next play time of the general medium a is 0s, the next play time of the general medium b is 2s, the next play time of the general medium c is 3s, the play duration of the medium 4 is 6s, and the next play time of the general medium in the media collection 4 is determined according to the following formula:
wherein T is i For the duration of play of the ith generic media in the media collection in the predetermined order, where i is an integer, t n For the next playing time of the nth general media in the media collection according to the predetermined sequence, where n is an integer, specifically, for the first general media a in the media 4 according to the predetermined sequence, the next playing time of the second general media b is the playing duration of the first media a, that is, 2s, and the next playing time of the third general media c is the sum of the playing duration of the first general media a and the playing duration of the second general media b, that is, 2s plus 1s, that is, 3s. It should be noted that, in the embodiment of the present invention, the program preview software may optionally perform a generalization operation on the general media information in the program to be previewed, that is, use the general media with the same playing duration as a group of media, because for the general media, the general media with the same playing duration must also have the same playing time next time, becauseIn this way, when determining the target preview media, a group of general media can be quickly acquired, so that the running speed of the preview playing software can be increased, and the processing efficiency of the processor corresponding to the preview playing software can be improved.
After determining the next play time for each media on the program editing interface, the program preview software will detect a screen refresh. Here, a screen refers to a screen of a device on which program preview software is running, for example, a display screen of a PC, for example, a display screen refresh frequency is typically 60 hz, that is, 60 times per second, that is, every 16.7ms, where a screen refresh is detected, that is, a refresh of the display screen is detected. When the screen refreshing is detected, responding to the screen refreshing, recording the screen refreshing time as a second moment, and then determining the preview duration time by the program preview software according to the first moment and the second moment, wherein the obtained value is obtained by subtracting the first value corresponding to the first moment from the second value corresponding to the second moment.
Further, the program preview software traverses next playing time of each media according to the determined preview duration, determines whether at least one media has a target preview media whose next playing time is equal to the preview duration, if so, schedules preview playing of the target preview media, and updates the next playing time of the target preview media so as to determine whether preview playing of the target preview media is performed according to the updated next playing time in response to the next preview playing.
Specifically, for example, if the preview play duration is 0s, that is, the difference between the second time of screen refresh and the first time of preview on is 0, media 1 to media 4 are traversed, and when the next play time of the general media a in media 1, media 2, media 3, and media 4 is determined to be 0, the general media a in media 1, media 2, media 3, and media 4 is preview played, and the respective corresponding next play times are updated. Specifically, as shown in fig. 3F, for media 1, the number of plays is 0 plus 1 before previewing the play of the media 1 to determine that the number of plays of the media 1 is 1. The next playing time is determined according to the determined playing times and the playing duration of the media 1, and may be obtained by multiplying the determined playing times and the playing duration, for example, that is, the next playing time of the media 1 is 2s. Correspondingly, for general media, the playing times and the next playing time determining process are similar to those of the media 1, and are not described herein, specifically, the playing times of the media 2 are updated to 1, and the next playing time of the media 2 is updated to 2s; and the number of play times of the media 3 is updated to 1, and the next play time of the media 3 is updated to 4s. For the general media a in the small container, which is the media 4, the next playing time is updated to be the sum of the current next playing time and the playing duration of the media 4, wherein the playing duration of the media 4 is the sum of the respective playing durations of a plurality of general media included in the media 4, that is, the general media a, the general media b and the general media c, wherein the playing duration of the media 4 is 6s, and for the general media a, the next playing time is updated to be the sum of the current next playing time 0 and the playing duration 6s of the media 4, that is, the next playing time of the general media a is updated to be 6s.
It should be noted that, the program preview software will respond to each screen refresh to traverse the media in the program to be previewed, so as to schedule and play the corresponding media, so as to complete the preview play of the media. In the embodiment of the invention, the corresponding media is scheduled to preview and play in response to each screen refresh, so that the phenomenon of frame loss of a picture can be avoided, and compared with the scheme of previewing and playing programs by using a timer in the prior art, the program previewing and playing problem can be realized, and the program previewing and playing delay is avoided. In addition, the program preview software periodically responds to the screen refreshing and updates the second moment, and judges whether the next playing time of at least one media accords with the preview condition, namely whether the next playing time of the target preview media is equal to the preview duration, and when the next playing time of the target preview media accords with the condition, the target preview media is previewed and updated.
In the above scheme, the preview duration is determined according to the first time of receiving the program to be previewed and the second time of refreshing the screen, the target preview media is determined according to the preview duration and the next playing time of the media in the program to be previewed, and the target preview media is scheduled to be previewed and played.
