(5): the server may replace the second program identification with the first program identification.
In this case, if the first program identifier included in the first program information is different from the second program identifier included in the second program information, the second program identifier may be replaced with the first program identifier, so as to obtain the modified initial program table.
Illustratively, the first program information includes a program identifier of program 1, and the second program information includes a program identifier of program 2. At this time, it may be determined that the second program identification included in the second program information is different from the first program identification included in the first program information. In this way, the second program identifier included in the second program information may be replaced by the first program identifier, so as to obtain the modified second program information, where the program identifier included in the modified second program information is program 1.
After the server replaces the second program identification with the first program identification, step (6) may be performed.
(6): the server searches advertisement information corresponding to each piece of program information in the initial program list.
After the server obtains the initial program list, the server may search for advertisement information corresponding to each piece of program information in the initial program list, and for at least one piece of third program information corresponding to the found advertisement information, the server may correct the corresponding third program information according to the advertisement information corresponding to each piece of third program information, thereby obtaining the corrected program list.
As an example, the server may obtain advertisement information corresponding to a plurality of programs identified by a plurality of program identifiers according to the plurality of program identifiers included in the initial program table. Among the programs identified by the program identifiers, there may be a program for which corresponding advertisement information cannot be acquired according to the program identifiers, that is, there is a program for which no advertisement is delivered.
The step (8) may be performed when at least one piece of third program information corresponding to the advertisement information is found, and the step (7) may be performed when at least one piece of third program information corresponding to the advertisement information is not found.
(7): the server may use the initial program table as the revised program table.
In this case, the server does not find at least one piece of third program information corresponding to the advertisement information, which indicates that no advertisement is inserted in any of the programs included in the initial program table, so that the start-stop time included in the initial program table does not need to be modified, and the initial program table can be directly used as a modified program table.
(8): the server determines the type of advertisement based on the advertisement information.
In some embodiments, the advertisement information includes an advertisement duration and an advertisement insertion point. In this way, for any piece of advertisement information in the at least one piece of advertisement information found according to the program identifier included in the initial program table, for convenience of description, it is referred to as first advertisement information, and the server may determine the type of the first advertisement corresponding to the first advertisement information according to the advertisement insertion point included in the first advertisement information. Wherein the type of the first advertisement comprises a pre-film advertisement and a film trailer advertisement.
As an example, the ad insertion point may be a time difference between the start time of the ad play relative to the start time of the program, or the end time of the program. In this way, the server may determine whether the type of the first advertisement corresponding to the first advertisement information is a pre-film advertisement or a post-film advertisement according to the advertisement insertion point included in the first advertisement information.
Optionally, the advertisement information may further include an advertisement duration and a type, so that it is possible to determine whether the first advertisement is a pre-trailer advertisement or a post-trailer advertisement directly according to the type included in the advertisement information.
If the type of the first advertisement is a pre-film advertisement, step (9) may be performed, and the start time in the start-stop time included in the third program information corresponding to the first advertisement information is corrected according to the advertisement duration included in the first advertisement information. If the type of the first advertisement is a trailer advertisement, step (10) may be performed to correct the end time in the start-stop time included in the third program information corresponding to the first advertisement information according to the advertisement duration included in the first advertisement information.
(9): the server may correct the start time in the start-stop time included in the third program information corresponding to the first advertisement information according to the advertisement duration included in the first advertisement information.
When the type of the first advertisement is a pre-film advertisement, the advertisement duration included in the first advertisement information may be obtained, and the start-stop time included in the third program information corresponding to the first advertisement information may be obtained. Thereafter, the start time of the start-stop time may be added to the advertisement time duration to obtain a corrected start time.
Illustratively, the first advertisement information includes an advertisement duration of 2min, and the third program information includes a start-stop time of 7:00, 7: 50. In this way, the server may add the start time 7:00 included in the start-stop time to the advertisement time duration 2min to obtain the corrected start time of 7:02, that is, the corrected start-stop time included in the third program information is 7:02, 7: 50.
(10): the server may correct the end time in the start-stop time included in the third section information corresponding to the first advertisement information according to the advertisement duration included in the first advertisement information.
When the type of the first advertisement is a trailer advertisement, the advertisement duration included in the first advertisement information may be obtained, and the start-stop time included in the third program information corresponding to the first advertisement information may be obtained. The advertisement duration may then be subtracted from the end time included in the start-stop time to obtain a corrected end time.
Illustratively, the first advertisement information includes an advertisement duration of 2min, and the third program information includes a start-stop time of 7:00, 7: 50. In this way, the server may subtract the advertisement duration from the ending time 7:50 included in the starting and ending time by 2min to obtain the corrected ending time of 7:48, that is, the corrected starting and ending time included in the third program information is 7:00, 7: 48.
For the multiple searched advertisement information, the server may refer to the above steps (9) and (10) to modify the start-stop time of the program information corresponding to each advertisement information, so as to obtain a modified program list. The server may then store the revised program table and send the revised program table to the terminal.
Step 302: and the server receives a review request sent by the terminal, wherein the review request carries the target program identifier selected from the corrected program list.
The terminal may receive the modified program table transmitted by the server, and store the modified program table. Then, when detecting a review operation of the user, the terminal may display the modified program list, and detect a selection operation of the user for a plurality of program identifiers included in the displayed modified program list, and when detecting the selection operation, the terminal may take a program identifier corresponding to the selection operation as a target program identifier, and send the target program identifier carried in the review request to the server.
Illustratively, after the terminal receives the revised program list, as shown in fig. 5, a review interface may be displayed, where the review interface includes the revised program list 501 and a play window 502, and the play window 502 may display a program identifier, a start-stop time, a play progress, and a program preview of a review program currently being played by the terminal. The play window 502 may also display a fast forward option, a rewind option, and a pause option for the review program currently being played.
Accordingly, the server may receive a review request sent by the terminal, and obtain the target operation identifier carried in the review request.
Step 303: and the server acquires the start-stop time of the target program identified by the target program identification from the corrected program list according to the target program identification.
In this embodiment of the application, after the server obtains the target program identifier, the server may search the target program identifier from a plurality of program identifiers included in the stored modified program list, and obtain the start-stop time of the target program identified by the target program identifier.
Step 304: and the server acquires a target video stream according to the start-stop time of the target program and the target program identifier, and sends the target video stream to the terminal so that the terminal plays the target video stream.
In the embodiment of the application, after the server acquires the start-stop time of the target program, the advertisement information of the advertisement to be delivered can be acquired according to the target program identifier, and the advertisement information of the advertisement to be delivered includes the identifier of the advertisement to be delivered.

In some embodiments, the start-stop time point of the advertisement playing in the live program can be further obtained according to the review program table, after a review request of a user is received, the server queries the advertisement to be played, the playing time of which is in accordance with the start-stop time point of the advertisement playing, and then issues the advertisement to be played to the television together with the review target video stream.
In some embodiments, the server further needs to acquire a time point of playing the advertisement and a relative time position of the live program stream during the live broadcast process, so as to insert the advertisement in the reviewed target video stream according to the determined relative time position.
It should be noted that the server stores the corresponding relationship between the program identifier and the advertisement information of the advertisement to be delivered. In this case, the server may search for the target program identifier in the corresponding relationship, and obtain advertisement information of the advertisement to be delivered corresponding to the target program identifier.
After the server acquires the advertisement information of the advertisement to be launched according to the target program identifier, the server can acquire the program video stream corresponding to the target program from the stored video stream according to the start-stop time of the target program, and can acquire the advertisement video stream according to the identifier of the advertisement to be launched, which is included in the advertisement information of the advertisement to be launched.
It should be noted that the stored video stream includes a plurality of video data packets. Wherein each video data packet in the plurality of video data packets comprises a time stamp for indicating a transmission time of the corresponding video data packet when live. The server may search, according to the start time and the end time included in the start-stop time of the target program, two video data packets having the same time stamps as the start time and the end time, respectively, from among a plurality of video data packets included in the stored video stream, and use the two video data packets and all video data packets between the two video data packets as the program video stream.
