< hardware configuration >

In the existing carousel method, an operator usually edits program lists of each carousel channel in a carousel mode in advance, and sets to cyclically play the program lists sequentially from a certain time point, so as to achieve a carousel effect. The channels in the carousel mode include, for example, a tv show channel, a movie channel, a variety channel, and the like. When accessing a carousel channel, a user will watch the program content of the program list provided by the channel from the video frame that the carousel channel is carousel to at the access time.

Taking fig. 1 as an example, the program list of a carousel channel in the carousel mode includes n videos, and the program list is sequentially played in a loop from a preset starting playing time. When user a accesses the carousel channel at 20:00, user a will start watching the program content of the program listings from the video frame (a certain video frame according to fig. 1 for video 1) that the carousel channel was carousel at 20: 00. When user B accesses the carousel channel at 00:00, user B will start watching the program content of the program listings from the video frame (a certain video frame according to fig. 1, video 3) that the carousel channel was carousel to at 00: 00. When user C accesses the carousel channel at 03:00, user C will start watching the program content of the program from the video frame (a certain video frame according to fig. 1, video 5) that specified the carousel channel to be carousel at 03: 00.

When user a, user B and user C all access the carousel channel at 03:00, user a, user B and user C will start watching the program content of the program from the video frame (a certain video frame of video 5 according to fig. 1) that the carousel channel has been carousel at 20: 00.

This means that, in the prior art, the same program list is provided for the carousel channel, and the program contents that can be viewed by different users through the carousel mode are the same, but in the case of different access times, the playing nodes of the program list that are viewed by different users are different. And under the condition of the same access time, the playing nodes of the program list watched by different users are also the same.

In order to meet the personalized requirements of different users, the invention provides a carousel mode for customizing a carousel program list for each user. Fig. 2a and 2b are schematic configuration diagrams of a carousel system 1000 for videos according to an embodiment of the present invention.

As shown in fig. 2a and 2b, the carousel system 1000 of video of the present embodiment includes a server 1100, a terminal device 1200, and a network 1300.

In one embodiment, the server 1100 may obtain a target video matching the target user according to a set period, and generate a carousel program of the target user according to the target video. The server 1100 sends the carousel program to the terminal device 1200 when receiving a request for acquiring a personalized program sent by the terminal device 1200.

The server 1100 may also obtain a target video matched with the target user when receiving a request for obtaining the personalized program list sent by the terminal device 1200, generate a carousel program list of the target user according to the target video, and send the carousel program list to the terminal device 1200.

The request for acquiring the personalized program list in this example may be sent to the server 1100 by the terminal device 1200 when the terminal device is powered on, or sent to the server 1100 by the terminal device 1200 when the terminal device enters the carousel mode, or sent to the server 1100 by the terminal device 1200 when the terminal device accesses a specified carousel channel. The designated carousel channel in this embodiment may be a carousel channel that is designated in advance according to an application scenario or a specific requirement and is used for playing a carousel program customized for a target user.

In another embodiment, the terminal device 1200 may also obtain a target video matching the target user when being powered on, entering a carousel mode, or accessing a designated carousel channel, and generate a carousel program of the target user according to the target video. When the terminal apparatus 1200 accesses the designated carousel channel, carousel is performed according to the carousel program.

Taking fig. 7 as an example, the designated carousel channel in the carousel mode includes user a's program list 1, user B's program list 2, and user C's program list 3. Program list 1, program list 2, and program list 3 each contain n videos. Specifically, the program list 1 comprises videos A1-An, the program list 2 comprises videos B1-Bn, and the program list 3 comprises videos C1-Cn. Each carousel is sequentially played back cyclically starting from the corresponding start play time. When user a accesses the specified carousel channel at 03:00, user a will start to view the program content of program 1 from the video frame (a certain video frame according to fig. 7, video a 5) that the specified carousel channel was carousel at 03: 00. When user B accesses the specified carousel channel at 03:00, user B will start viewing the program content of program guide 2 from the video frame (a certain video frame according to fig. 7, video B5) that the specified carousel channel was carousel at 03: 00. When user C accesses the designated carousel channel at 03:00, user C will start viewing the program content of program listing 3 from the video frame (a certain video frame according to fig. 7 for video C5) that the designated carousel channel was carousel to at 03: 00.

Therefore, through the embodiment of the invention, different carousel program lists are customized for each user, so that under the condition that the access time of different users is the same, the program contents which can be watched through the carousel mode can be different, and the personalized requirements of different users can be met.

< method examples >

Fig. 3 is a schematic flow chart of a carousel method of video according to an embodiment of the present invention.

In one example, the video carousel method shown in fig. 3 may be implemented by only the terminal device alone, or may be implemented by both the server and the terminal device. In one embodiment, the terminal device may be the terminal device 1200 as shown in fig. 2a or fig. 2b, and the server may be the server 1100 as shown in fig. 2a or fig. 2 b.

As shown in fig. 3, the video carousel method of the present embodiment includes the following steps S3100 to S3200:

step S3100, under the condition that the occurrence of the trigger event for customizing the carousel program list for the target user is detected, acquiring a target video matched with the target user.

The target video matched with the target user can be preset for the target user, or can be obtained by the electronic equipment executing the embodiment of the invention through matching for the target user. The following describes an embodiment of obtaining a target video for a target user by matching with an electronic device.

In an embodiment where step S3100 is performed by a terminal device, the triggering event for customizing the carousel program for the target user may be turning on the terminal device, entering a carousel mode, or accessing a specified carousel channel.

In this embodiment, the target user may perform a corresponding operation to trigger the terminal device to turn on, enter the carousel mode, or access the designated carousel channel. Specifically, the target user may execute a corresponding operation through a remote controller, a keyboard, a mouse, or a touch screen, to trigger the terminal device to start up, enter the carousel mode, or access the designated carousel channel.

The designated carousel channel in this embodiment may be a carousel channel that is designated in advance according to an application scenario or a specific requirement and is used for playing a carousel program customized for a target user. The carousel channel may also include other channels in addition to the designated carousel channel. Specifically, the operator may set program lists corresponding to each of the other carousel channels in advance. The designated carousel channel corresponds to a single carousel program customized for the target user according to the method of the present embodiment.

The terminal equipment can acquire the target video matched with the target user from the video stored in the terminal equipment, and can also acquire the video matched with the target user from the server.

In an embodiment where step S3100 is performed by a server, the triggering event for customizing the carousel playlist for the target user may be reaching a set period; the server may also receive a request for obtaining the personalized program list from the terminal device. The setting period may be set in advance according to an application scenario or a specific requirement. For example, the set frequency may be 1 day or 1 week.

In this embodiment, the request for obtaining the personalized program list may be automatically sent to the server by the terminal device when the terminal device is powered on, may also be sent to the server by the terminal device when the terminal device enters the carousel mode, and may also be sent to the server by the terminal device when the terminal device accesses the specified carousel channel.

In an example, the target user may be all users using the terminal device, and then the terminal device may carry a device identifier of the terminal device in a request sent to the server to obtain the personalized program list, so that the server identifies the identity of the target user according to the device identifier carried in the request, and further obtains the target video matched with the target user. The device identifier may be an identification code for uniquely identifying the terminal device.

In another example, the target user may also be a user using a target account. When a target user logs in a terminal device through a target account of the target user, the terminal device may carry the target account of the target user in a request sent to a server for acquiring a personalized program list, so that the server identifies the identity of the target user according to the target account carried in the request, and further acquires a target video matched with the target user. The target account may be used to uniquely identify the user, and may be, for example, a user name, a mobile phone number, a mailbox, or the like.

Specifically, the obtaining of the target video matched with the target user may further include the following steps S3110 to S3120:

in step S3110, a user image of a target user is acquired.

In one example, the user representation of the target user may be pre-constructed and stored in the electronic device implementing the embodiments of the present invention, and may be updated at a set frequency. The electronic device may directly acquire a pre-stored user profile of the target user when performing the step S3110.

In this embodiment, the trigger event for customizing the carousel program for the target user further includes an update of the user profile of the target user. Then, when the user profile of the target user is updated, steps S3100 to S3200 in the present embodiment are executed to regenerate the carousel program of the target user.

In another example, the user representation may also be constructed upon detecting the occurrence of a triggering event that customizes the carousel for the target user.

Specifically, the step of constructing the user profile of the target user may include the following steps S3111 to S3112:

step S3111, a target user attribute reflecting the viewing habit of the target user is acquired.

The target user attribute may include, among other things, historical viewing data of the target user and/or personal information of the target user. The user attribute may be stored in the terminal device used by the target user or in the server.

The historical viewing data may be historical data of the target user viewing the video over a statistical period. For example, the historical viewing data may include the name, type, and viewing progress of the video viewed. The type of the video can be preset for the video, and includes, for example, ancient historical dramas, love dramas, spy dramas, war resistant dramas, martial arts dramas, campus dramas, comedy movies, action movies, thrillers movies, hedonic events, kids, animation, documentaries, laughters, games, sports, and the like.

In one example, the historical viewing data of the target user within the statistical period may be obtained. The statistical time period in this embodiment may be set in advance according to an application scenario or a specific requirement. For example, the statistical period may be within the past week. Then, the historical viewing data acquired in step S4100 may be viewing data of the target user within the past week.

In another example, a first set number of viewing data recently viewed by the target user may be obtained. The first set number in this embodiment may be set in advance according to an application scenario or a specific requirement. For example, the first set number may be 10, and then the historical viewing data acquired in step S4100 may be 10 viewing data that the target user has viewed most recently.

The personal information may be information reflecting the user's situation, and may include information such as the user's age, the user's sex, the region where the user is located, and the like. The personal information in this embodiment may be submitted to the server by the user after registering the account, and stored in the server.

Step S3112, constructing a user portrait of the target user according to the target user attribute.

The user image in this embodiment is image data representing the attribute related to the video viewing behavior of the corresponding user.

Data modeling can be performed by taking a preset user tag as output according to a plurality of user attributes (including historical viewing data and/or personal information of a corresponding user) as input in advance to obtain a data model. And inputting the target user attribute into the data model to obtain the user portrait of the target user.

After the user portrait of the target user is obtained by the present embodiment, the process continues to step S3120.

And S3120, obtaining a target video matched with the target user according to the user portrait.

In one example, a recommendation model may be created in advance to obtain a target video matching a target user according to a user profile based on the recommendation model. The recommended model may be a model trained from a collection of training samples including user portraits for obtaining a target video matching a target user.

Through the recommendation model, the target video matched with the target user is obtained according to the user portrait of the target user, the information obtaining behaviors of the target user and the target user can be integrated, and the video matched with the target user is accurately and effectively obtained, so that the follow-up steps are combined, the target user is accurately played in a video carousel mode, the actual requirements of the target user are actually met, and the user experience of the target user is improved.

After the user portrait of the target user is obtained, the target video matched with the target user can be obtained according to the user portrait.

In one example, the step of obtaining the target video matching the target user according to the user profile may further include the following steps S3121 to S3123:

in step S3121, a plurality of preset candidate videos are acquired.

The candidate videos in this embodiment may be all videos that may be provided by the electronic device that executes the embodiment of the present invention; the video with the score exceeding a preset score threshold value can be also used; the video with the watching times exceeding a preset time threshold value can also be displayed; or may be a video showing within a set period of time. The scoring threshold, the number threshold or the set period may be preset according to an application scenario or a specific requirement. For example, the score threshold may be 5 points, the number threshold may be 1000 ten thousand times, and the set period may be within the past month.

And S3122, obtaining the matching degree of each candidate video and the target user according to the user portrait.

In one example, a video image of each candidate video may be determined, and a matching degree between the corresponding candidate video and the target user may be obtained according to the video image and the user image. The video image is image data representing the attribute of the corresponding video. For example, a video image may include a type of corresponding video.

And S3123, selecting the candidate video with the matching degree meeting the preset conditions as the target video.

In one example, the preset condition may be that the matching degree is greater than or equal to a preset threshold value of the matching degree. Then, the candidate video with the matching degree greater than or equal to the threshold value of the matching degree may be selected as the target video. The threshold of the matching degree may be set according to an application scenario or specific requirements, for example, the threshold of the matching degree may be set to 80%.

In another example, the preset condition may be a second set number of the largest matching degrees. Then, a second set number of subsequent videos with the largest matching degree may be selected as the target video. The second set number may be set according to an application scenario or a specific requirement, and for example, the second set number may be 10.

Specifically, the candidate videos may be sorted in a descending order according to the matching degree, and a sorting value of each candidate video is obtained; and selecting candidate videos with the ranking values smaller than or equal to a second set number as target videos.

The target video obtained by the above embodiment may be one or more.

After the target video matching the target user is acquired through the present embodiment, the following step S3200 is continuously executed.

Step S3200, the carousel program of the target user is generated according to the target video.

The carousel program may include a name of the target video, and may further include a playing time period or a playing time of the target video.

Specifically, the playing sequence of each target video may be predetermined; and obtaining the playing time interval or the playing time of each target video in the carousel program according to the playing sequence and the playing time length of each target video and the preset initial playing time of the carousel program. The starting playing time of the carousel program may be set according to an application scenario or a specific requirement, for example, the starting playing time of the carousel program may be set to 00:00 of the current day on which the carousel method of this embodiment is executed.

For example, in the case where the target videos in the target videos obtained through step S3100 include video a1, video a2, video A3, video a4, and video a5, if the view length of each target video is 2 hours, the determined playing sequence is video a1, video A3, video a5, video a4, and video a2, and the preset starting playing time of the carousel program is 00:00 of the day, the obtained carousel program may be as shown in table 1 or table 2 below:

TABLE 1

Video A3	02:00:00
		Video A5	04:00:00
Video A4	06:00:00
		Video A2	08:00:00

In an example, the playing order of the target videos may be obtained by random sequencing, or by sequencing the target videos according to a preset sequencing parameter. The ranking parameter is a parameter used as a basis for ranking the target video, and may include any one or any combination of scores, popularity, showing time, number of comments, and matching degree with the target user, for example.

In an embodiment of the present invention, the target videos obtained in step S3100 are plural, and the step of generating the carousel program from the target videos may further include steps S3210 to S3230 as follows:

step S3210 determines a value of a ranking parameter of each target video, respectively.

The ranking parameter is a parameter used as a basis for ranking the target video, and may include any one or any combination of scores, popularity, showing time, number of comments, and matching degree with the target user, for example.

In the case that the sorting parameter includes the matching degree with the target user, the method for determining the matching degree between the target video and the target user may refer to the foregoing embodiments, and details are not described here.

The score, the popularity, the showing time, and the number of comments of the target video may be pre-stored in the electronic device executing the embodiment, and may be directly obtained when step S3210 is executed.

Step S3220, according to the value of the sorting parameter, sorting the plurality of target videos, and acquiring a sorting value of each target video.

The sorting manner in this embodiment may be, for example, a descending sorting manner from large to small, an ascending sorting manner from small to large, or other self-defined sorting manners.

Under the condition that the sequencing parameters comprise a plurality of parameters, determining the comprehensive score of the corresponding target video according to the value of the sequencing parameter of each target video; and sequencing the plurality of target videos according to the comprehensive scores, and acquiring a sequencing value of each target video.

Step S3230, generate the carousel program according to the ranking value of each target video.

In one embodiment, generating the carousel program according to the ranking value of each target video may include steps S3231 to S3232 as follows:

in step S3231, priorities of a plurality of preset play periods are acquired.

Specifically, the playing time period may be preset according to an application scenario or a specific requirement, for example, the time period between any two adjacent integer points in a day may be used as the preset playing time period, and the obtained playing time period may include 00:00 to 01:00, 01:00 to 02:00, … …, 22:00 to 23:00, and 23:00 to 24: 00.

In one example, the priority of each playing period may be preset, and may be directly obtained when step S3231 is performed.

In another example, obtaining the priorities of the plurality of preset play periods may further include steps S3231-1 to S3231-3 as follows:

step S3231-1, obtaining historical viewing data of the target user.

The historical viewing data in this embodiment may include the specific viewing time of the viewed video.

In step S3231-2, the number of viewing times in each play period is determined based on the historical viewing data, respectively.

Step S3231-3, determines the priority of each playing period according to the number of viewing times.

Specifically, the playing period with the larger number of viewing times may have a higher priority; the less the number of viewing times, the lower the priority of the playing period.

After the priority of each playing period is acquired, step S3232 is executed.

Step S3232, generating a carousel program according to the priority of each playing time interval and the ranking value of each target video.

Specifically, when the target videos are sorted in a descending order, the target videos with smaller sorting values may be set in a playing time period with a higher priority for playing.

For example, when the priority between the playing time periods 19: 00-20: 00 is the highest and the ranking value of the target video A3 is the smallest, the target video A3 in the carousel program list may be set to be played within the time periods 19:00: 00-20: 00: 00.

Therefore, the target video with the highest matching degree with the target video can be observed by the user in the period of watching frequently, and the user experience is improved.

In the example shown in fig. 4, if the target video is sorted in descending order, if the playing period with the largest number of viewing times of the target user is 19:00 to 20:00, and then the playing period is 12:00 to 13:00, the playing period 19:00 to 20:00 can be set to have the highest priority, and the playing period 12:00 to 13:00 can be set to have the second highest priority.

The target video with the ranking value of 1 can be set in the playing time interval 19: 00-20: 00 with the highest priority for playing, and the target video with the ranking value of 2 can be set in the playing time interval 12: 00-13: 00 with the second highest priority for playing. The other target videos may be set in the order of the predetermined start playing time of the carousel program.

After the carousel program is obtained through the steps of this embodiment, the following step S3300 may also be continuously performed.

In step S3300, if the target user accesses the carousel channel corresponding to the carousel program (i.e., the designated carousel channel), carousel is performed according to the carousel program.

This step S3300 may be performed by the terminal device.

In the embodiment where steps S3100 and S3200 are also performed by the terminal device, if the terminal device acquires the target video matching the target user and generates the carousel program of the target user according to the target video when the specified carousel channel is accessed, after the terminal device generates the carousel program, carousel is performed according to the carousel program. If the terminal device obtains the target video matched with the target user and generates the carousel program list of the target user according to the target video under the condition of starting or entering the carousel mode, the terminal device can perform carousel according to the carousel program list instead of performing carousel according to the carousel program list after generating the carousel program list when receiving the operation that the target user accesses the appointed carousel channel.

In the embodiment where steps S3100 and S3200 are performed by the server, the server may send the carousel program to the terminal device after generating the carousel program, so that the terminal device performs carousel according to the carousel program when receiving an operation of the target user to access the specified carousel channel. The server may also be configured to send the carousel program to the terminal device only when receiving a request for the terminal device to access a specified carousel channel after generating the carousel program, so that the terminal device performs carousel according to the carousel program.

And when the terminal equipment carries out carousel according to the carousel program, carrying out circular playing sequentially according to the playing time interval or the playing time of each target video in the carousel program.

In an embodiment of the present invention, the carousel method may further include determining a playing time point of a target video corresponding to the current time in the carousel program at the current time.

The current time in this embodiment may be the time when step S3310 is executed.

In one example, determining the playing time point of the target video corresponding to the current playing time in the carousel program at the current time may further include steps S4100 to S4300 as follows:

step S4100 determines the total playing time length of the carousel program.

And the total playing time length of the carousel program list is the sum of the playing time lengths of all the target videos in the carousel program list.

Step S4200, determining a playing node of the carousel program at the current time according to the total playing time and a preset starting playing time for playing the carousel program.

The playing node of the carousel program at the current moment can be obtained by determining the time length of the carousel program from the initial playing moment to the current moment and then determining the remainder of the time length divided by the total playing time length.

For example, when the total playing time is 12 hours, the current time is 15:00:00, and the preset starting playing time is 00:00:00, the obtained playing node of the carousel program list at the current time is 3:00: 00.

Step S4300, according to the playing node of the carousel program at the current time, obtaining the playing time point of the target video at the current time corresponding to the current time.

The target video corresponding to the playing node of the carousel program at the current time may be determined by traversing the carousel program, and then the playing time point of the target video corresponding to the current time at the current time may be obtained according to the playing time or the playing time period of the target video.

In the example that the obtained carousel program is as shown in table 2, if the playing node of the obtained carousel program at the current time is 3:00:00, the playing time point of the target video corresponding to the current time at the current time is 60 minutes of video a 3.

On this basis, the step of performing carousel according to the carousel program list in step S3300 may include: and performing carousel on the carousel program from the playing time point of the target video corresponding to the current time at the current time.

In one example, the target user may also trigger the terminal device to display at least part of the carousel program for the target user to view based on the terminal device performing the operation of viewing the carousel program. The displayed carousel program list comprises a currently played target video and playing time thereof, and a next target video in the carousel program list and playing time thereof. The showing details of the carousel program may be as shown in fig. 5a or fig. 5 b.

In the interface shown in fig. 5a, the terminal device may display all target videos and playing times thereof included in the carousel program according to an operation performed by the target user to view the carousel program, and highlight the target video being played and the playing time thereof, so that the target user may determine the currently viewed program.

In the interface shown in fig. 5b, the terminal device may display only a part of the carousel program, including the currently played target video and its playing time, and the next target video and its playing time, according to the operation performed by the target user to view the carousel program, and highlight the currently played target video and its playing time, so that the target user can determine the currently viewed program.

In the embodiment of the invention, under the condition that the occurrence of the trigger event for customizing the carousel program list for the target user is detected, the target video matched with the target user is obtained, the carousel program list is generated according to the target video, and the carousel is carried out according to the carousel program list when the target user accesses the appointed carousel channel. Therefore, the carousel program is customized for each user, the individual requirements of different users can be met, and the carousel effect of thousands of people can be realized. In addition, because the embodiment does not need the participation of operators, the labor cost can be saved.

In an embodiment of the present invention, after the foregoing steps S3100 to S3200 are executed to obtain the carousel program of the target user, the carousel program may be stored in its own cache and/or in a database.

In this example, the storage time period of the cache and the database of the electronic device implementing this embodiment may be preset, and then, when the stored carousel program of the target user exceeds the corresponding storage time period, the carousel program is cleared. The stored carousel program can be emptied according to a preset cleaning period.

The storage time can be set according to application scenes or specific requirements. For example, the storage age of the database may be 1 day, the storage age of the cache of the server may be 2 hours, and the storage age of the cache of the terminal device may be 7 days.

Then, after the database clears the carousel program list matching the target user, if a trigger event for customizing the carousel program list for the target user is detected, the carousel program list needs to be customized for the target user again. The target user's carousel program generated each time may be the same or different.

< example 1>

The following describes a process implemented by a video carousel method according to an embodiment of the present invention. In example 1, for example, when an operation of accessing a specified carousel channel is performed while a target user watches the carousel channel through a terminal device, the terminal device is triggered to send a request for accessing the specified carousel channel to a server, the server obtains a user image of the target user in response to the request, obtains a target video matched with the target user according to the user image, generates a carousel program according to the target video, and sends the carousel program to the terminal device, and the terminal device performs carousel according to the received carousel program. Referring to fig. 6, the method may specifically include:

in step S5100, an operation of accessing the designated carousel channel is performed for the terminal apparatus 1200 by the target user.

Specifically, the operation may be an operation performed by the target user for clicking the designated carousel channel by using an auxiliary device such as a touch screen, a remote controller, a mouse, or a keyboard, with respect to the terminal device 1200.

In step S5200, a request for obtaining the personalized program list is issued to the server by the terminal apparatus 1200 in response to the operation.

In step S5310, the server 1100 obtains the user representation of the target user in response to the request.

The user portrait can be stored in the server in advance and updated according to a set period; the user representation of the target user can be constructed according to the target user attribute reflecting the watching habits of the target user in response to a request for accessing the appointed carousel channel sent by the terminal equipment.

The user attributes may include historical viewing data of the target user and/or personal information of the target user. The historical watching data may be the historical data of the videos watched by the target user in the statistical time period, or the first set number of watching data watched by the target user recently. The personal information may be information reflecting the user's situation, and may include information such as the user's age, the user's sex, the region where the user is located, and the like.

In step S5320, the server 1100 obtains a target video matching the target user according to the user representation of the target user.

In step S5410, the server 1100 determines the matching degree of each target video with the target user, respectively.

In step S5420, the server 1100 performs descending order sorting on the multiple target videos according to the matching degree, and obtains a sorting value of each target video.

In step S5431, priorities of a plurality of preset play periods are acquired by the server 1100.

The priority of each playing period may be preset, or may be determined according to the viewing times of each playing period obtained from the historical viewing data of the target user.

In step S5432, the server 1100 generates a carousel program of the target user according to the priority of each playing time period and the ranking value of each target video.

For example, the priority of a plurality of preset play periods may be determined at the number of viewing times per play period obtained from the historical viewing data of the target user.

As shown in fig. 4, if it is determined that the playing period with the largest number of viewing times of the target user is 19:00 to 20:00 and then the playing period is 12:00 to 13:00, the playing period 19:00 to 20:00 may be set to have the highest priority, and the playing period 12:00 to 13:00 may be set to have the second highest priority.

The target video with the ranking value of 1 can be set in the playing time interval 19: 00-20: 00 with the highest priority for playing, and the target video with the ranking value of 2 can be set in the playing time interval 12: 00-13: 00 with the second highest priority for playing. The other target videos may be set in the order of the predetermined starting playing time of the carousel program.

In step S5510, the server 1100 determines the total play time of the carousel program.

In step S5520, the server 1100 determines a playing node of the carousel program at the current time according to the total playing time and the preset initial playing time for playing the carousel program.

The playing node of the carousel program at the current moment can be obtained by determining the time length of the carousel program from the initial playing moment to the current moment, and then determining the remainder generated by dividing the time length by the total playing time length.

In step S5530, the server 1100 obtains a playing time point of the target video at the current time corresponding to the current time according to the playing node of the carousel program at the current time.

Through traversing the carousel program, the target video corresponding to the playing node of the carousel program at the current moment can be determined. And then according to the playing time or playing time interval of the target video, the playing time point of the target video at the current moment corresponding to the current moment can be obtained.

In step S5600, the server 1100 transmits the carousel program and the target video corresponding to the current time to the terminal device at the play time point of the current time.

Step S5700, the terminal device 1200 receives the carousel program sent by the server and the play time point of the target video at the current time, which corresponds to the current time.

In step S5800, the terminal device 1200 performs carousel on the carousel program from the play time point of the target video corresponding to the current time at the current time.

The terminal device may first obtain a source file corresponding to the playing time point of the target video corresponding to the current time from the server for playing according to the playing time point of the target video corresponding to the current time at the current time, and perform carousel according to the carousel program.

As shown in fig. 7, according to the carousel method in this example, the generated carousel program of user a is program list 1, the carousel program of user B is program list 2, and the carousel program of user C is program list 3. Program list 1, program list 2, and program list 3 each contain n videos. Specifically, the program list 1 comprises videos A1-An, the program list 2 comprises videos B1-Bn, and the program list 3 comprises videos C1-Cn. Each carousel is sequentially played back cyclically starting from the corresponding start play time.

When user a accesses the designated carousel channel at 03:00, user a will start viewing the program content of program listing 1 from the video frame (corresponding to the playing time point at 03:00 of video a5 according to fig. 7) that the designated carousel channel was carousel at 03: 00. When the user B accesses the specified carousel channel at 03:00, the user B will start to watch the program content of the program guide 2 from the video frame (corresponding to the playing time point at 03:00 of the video B5 according to fig. 7) that the specified carousel channel was carousel at 03: 00. When the user C accesses the specified carousel channel at 03:00, the user C starts to view the program content of the program guide 3 from the video frame (corresponding to the playing time point at 03:00 of the video C5 according to fig. 7) that the specified carousel channel has been carousel at 03: 00.

Therefore, the program list of the appointed carousel channel is customized for each user, so that the watched video contents can be different when different users access the appointed carousel channel at the same time, and the individual requirements of different users are met.

< example 2>

On the basis of the above example 1, the target user may also trigger the terminal device to display at least part of the carousel program for the target user to view based on the terminal device performing the operation of viewing the carousel program. The displayed carousel program list comprises a currently played target video and playing time thereof, and a next target video in the carousel program list and playing time thereof. The showing details of the carousel program may be as shown in fig. 5a or fig. 5 b.
