In some embodiments, when the first multimedia resource is a juvenile program, the user may also send a switching operation to the display device 200 when the latest accumulated playing duration obtained according to the playing duration of the first multimedia resource does not reach the set shutdown duration, and after receiving the switching operation, the display device 200 switches the first multimedia resource currently being played to the second multimedia resource, and detects the second media resource attribute of the second multimedia resource.

In some embodiments, if the second multimedia asset represented by the second asset attribute is a non-juvenile program, that is, the playing juvenile program is switched to a non-juvenile program, then it may be that the child does not watch the display device after watching the program for a certain period of time, and the parent or the ancestor continues to watch the display device. At this time, the display device 200 adds the obtained playing time length of the first multimedia asset to the total playing time length of the juvenile program, and does not obtain the playing time length of the second multimedia asset.

In some embodiments, if the second media asset attribute indicates that the second multimedia asset is a juvenile program, that is, the playing juvenile program is switched to another juvenile program, at this time, the viewing interests of the child may be changed, and the playing program is switched. At this time, the display device 200 has stopped playing the first multimedia asset and recorded the playing duration of the first multimedia asset, and the display device 200 may add the obtained playing duration of the first multimedia asset to the total playing duration of the juvenile program. And, the display device 200 continues to acquire the playing duration of the second multimedia resource, and adds the acquired playing duration of the second multimedia resource to the total playing duration of the juvenile program watched by the user, so as to obtain the accumulated playing duration.

The above describes the procedure in which the display apparatus 200 acquires the play time length of the juvenile program when the juvenile program is played, to acquire the cumulative play time length of the juvenile program watched by the user on the same day.

S605: and when the accumulated playing time length reaches the watching time length, controlling to stop watching the first multimedia resource.

In some embodiments, when the cumulative playing time of the juvenile program watched by the user on the same day reaches the set viewing time, the display device may control the user to stop watching the first multimedia resource currently played. For example, the display device 200 may control shutting down, locking a screen, or pausing playing the first multimedia asset.

In some embodiments, when the accumulated playing time period reaches the viewing time period, the display device 200 may obtain the playing progress of the first multimedia asset currently played.

In some embodiments, if the latest accumulated playing time length obtained according to the playing time length of the first multimedia resource does not reach the set shutdown time length, after the user switches the first multimedia resource to the second multimedia resource, when watching the second multimedia resource, the accumulated playing time length reaches the shutdown time length, and then the playing progress of the second multimedia resource is obtained. For example, the child is 2-4 years old, the corresponding shutdown time is less than or equal to 1 hour, the child views the first multimedia resource for 20 minutes, views the second multimedia resource for 40 minutes, and the cumulative playing time added to the two is 1 hour, at which time the display device 200 needs to obtain the playing progress of the second multimedia resource.

In some embodiments, when the multimedia asset is played through the playing component in the display device 200, the starting time may be recorded, the playing timing is performed based on the starting time, and the playing duration of the first multimedia asset may be obtained through the timing duration. And, the display device 200 may obtain the total duration of the first multimedia resource from the media asset data, and compare the playing duration with the total duration to obtain the playing progress.

In some embodiments, the display device 200 may obtain the playing progress of the first multimedia asset through the playing progress bar of the first multimedia asset.

In the above-described process, the viewing time period set by the display apparatus 200 is the daily cumulative viewing time period.

In some embodiments, the viewing duration set by the display apparatus 200 may also be a single viewing duration. When the shutdown time is the single viewing time, if the playing time of each single juvenile program reaches the viewing time, the display device 200 further obtains the playing progress of the currently played juvenile program. If the cumulative playing time length of the continuous plurality of juvenile programs reaches the viewing time length, the display device 200 further obtains the playing progress of the currently played juvenile program.

In some embodiments, the display device 200 may also obtain the single viewing duration and the daily accumulated viewing duration at the same time, i.e., the shutdown duration includes the single viewing duration and the daily accumulated viewing duration. The process of determining whether to acquire the currently played juvenile program according to the comparison of the playing time length and the shutdown time length is the same as that described above.

In some embodiments, if the playing progress of the current multimedia resource acquired by the display device 200 is less than the preset threshold, a play shutdown prompt is controlled to prompt the user that the display device will be automatically shutdown after the first preset duration. And if the playing progress is greater than or equal to a preset threshold, controlling automatic shutdown, wherein the preset threshold is set according to the tail part of the multimedia resource.

A schematic diagram of a display effect of the multimedia asset playing progress reaching a preset threshold according to some embodiments is exemplarily shown in fig. 7. Fig. 8 is a schematic diagram illustrating a display effect of a multimedia asset playing progress not reaching a preset threshold according to some embodiments. Referring to fig. 7 and 8, the display apparatus 200 compares the acquired play progress of the multimedia asset currently being played with a preset threshold, wherein the preset threshold may be set to 95%, and the remaining 5% is typically the end of the clip. As shown in fig. 7, the multimedia asset has been played for 38 minutes and 50 seconds, and its total duration is 40 minutes and 30 seconds, so 95.5% has been viewed and has been greater than the preset threshold. As shown in fig. 8, the multimedia asset has been played for 10 minutes 56 seconds, which has a total duration of 40 minutes 30 seconds, so 26.9% has been viewed, less than the preset threshold.

In some embodiments, when the playing progress of the multimedia asset being played is greater than or equal to the preset threshold, for example, greater than or equal to 95%, it may be determined that the multimedia asset being played is already played to the tail portion, and at this time, the display device 200 may be directly turned off. For example, when the playing duration reaches the shutdown duration, the playing progress of the multimedia resource being played is 98%, and the playing progress is at the tail part of the animation album, and the display device 200 is controlled to be shutdown at this time, so that the children cannot feel too big.

In some embodiments, when the playing progress of the multimedia asset being played is less than a preset threshold, such as less than 95%, the multimedia asset currently being played may be just started or may be played to a part in the slice, and in this case, the child may be highly attentive to the multimedia asset currently being played. The display device 200 may not perform the shutdown operation first, but control to play a shutdown prompt to prompt the user that the display device 200 will be automatically shutdown after the first preset time period, that is, prompt the user that the display device 200 will be shutdown, so that the child currently watching the program is ready for the psychological preparation that is about to be shutdown.

In some embodiments, the display device 200 controls the display 260 to display a floating layer on the current playing interface, where the floating layer is used to load text information that prompts the user that the display device will be automatically turned off after the first preset period of time. A display effect schematic of the display device 200 playing a shutdown prompt according to some embodiments is illustrated in fig. 9. In conjunction with fig. 9, a floating layer may be displayed on the current playing interface, where the floating layer is loaded with a "shutdown prompt: the child, you have seen the cartoon for a time as fast as back, and automatically shuts down after 2 minutes ", where the first preset time period is 2 minutes. After seeing the prompt, the child knows that the display device 200 is about to be turned off.

In some embodiments, the display device 200 may control the floating layer to be hidden after displaying a second preset duration on the current playing interface, where the second preset duration is less than the first preset duration. For example, the display device 200 may set the floating layer to a separate DOM (Document Object Mode, document object model) layer, and after the floating layer has been exposed for 10 seconds, hide, i.e., after 10 seconds, set the DOM layer in which the floating layer is located to an invisible state.

In some embodiments, the display device 200 may be turned off by the user after controlling the floating layer to be presented on the current playing interface. If the closing button at the upper right corner of the floating layer is selected through the remote controller, or a voice command of closing prompt is input to the display device 200, the display device 200 can hide the floating layer.

In some embodiments, the text information loaded on the float may not be known due to some children being older, such as children between 2-4 years of age. Therefore, the display device 200 may further control a speaker communicatively connected to the display device 200 to play a voice prompt, where the voice prompt is a voice message for prompting a user that the display device will be automatically turned off after the first preset time period.

In some embodiments, the display device 200 may play the voice information using a speaker while the floating layer is being shown on the current playing interface when the shutdown prompt is played.

In some embodiments, when the display device 200 controls to stop watching the current first multimedia asset, the obtained accumulated playing time length of the juvenile program watched by the current user may be compared with the watching time length to obtain the remaining watching time length. The display device 200 obtains the playing progress of the currently watched first multimedia asset, and obtains the remaining playing duration of the first multimedia asset according to the total duration and the playing progress of the first multimedia asset. If the remaining playing duration is smaller than the remaining viewing duration, the display device 200 sets a shutdown prompt according to the remaining playing duration, so as to prompt a user that the display device 200 will be automatically shutdown after the remaining playing duration. If the remaining playing time period is longer than the remaining viewing time period, the display device 200 sets a shutdown prompt according to the remaining viewing time period to prompt a user that the display device 200 will be automatically shutdown after the remaining viewing time period.

For example, for a child viewing time of 1 hour, the child's cumulative playing time for the juvenile program being viewed on the day is 55 minutes, with the remaining viewing time being 5 minutes. The remaining playing time of the animation film being watched at this time is 4 minutes, the display device 200 may prompt the user to shut down after 4 minutes. For another example, if the remaining playing time of the animation film being watched at this time is 20 minutes, the display device 200 may prompt the user to shut down after 5 minutes.

The process of viewing duration control is further described below with reference to the accompanying drawings.

A timing diagram of a method of viewing duration control according to some embodiments is illustrated in fig. 10. As shown in fig. 10, the server 400 may obtain information such as attributes of the user, user preferences, lifestyle habits, and user behaviors in advance, calculate user portrait data, and obtain the age of the child. And according to expert advice, a mapping relation between the age of the child and the viewing duration is established. After receiving the user's power-on operation, the display device 200 may send an acquisition request including the user identification to the server 400. The server 400 obtains the child ages from the corresponding user profile data according to the user identifications and queries the corresponding viewing durations through the child ages. The server 400 feeds back the viewing duration to the display device 200, and the display device 200 buffers the viewing duration locally.

The display device 200 plays the first multimedia asset corresponding to the asset control in response to the selection of the asset control input by the user, and views the first asset attribute. If the first media asset attribute characterizes the first multimedia asset as a non-juvenile program, the display device 200 does not acquire the play duration. When the display device 200 plays the non-juvenile program, a switching operation input by the user is received, the first multimedia resource being played is switched to the second multimedia resource, and the second media resource attribute is checked. The display device 200 determines whether to acquire the playing duration of the second multimedia asset according to the second media asset attribute. If the first media asset attribute characterizes the first multimedia asset as a juvenile program, the display device 200 obtains a playing time length thereof, so as to obtain an accumulated playing time length of the juvenile program watched by the user on the same day according to the playing time length thereof. When the accumulated playing time length reaches the shutdown time length, the display device 200 further obtains the playing progress of the first multimedia resource. If the playing progress is smaller than the preset threshold, the playing shutdown prompt is controlled to prompt the user that the display device 200 is shutdown. And if the playing progress is greater than or equal to a preset threshold value, controlling the display equipment to be automatically turned off.

When the display device 200 plays the first multimedia asset belonging to the juvenile program and the accumulated play time period does not reach the viewing time period, the user inputs a switching operation. The display apparatus 200 acquires the second media asset attribute of the switched second multimedia asset in response to the switching operation of the user. When the second multimedia resource is a non-juvenile program, recording the playing time length of the first multimedia resource, and accumulating the playing time length into the accumulated playing time length. And does not acquire the playing time length of the second multimedia resource. When the second multimedia resource is a juvenile program, the playing time length of the second multimedia resource is obtained, and the accumulated playing time length is obtained based on the playing time lengths of the two multimedia resources. If the accumulated playing time length reaches the viewing time length, the display device 200 further obtains the playing progress of the second multimedia resource. If the playing progress is smaller than the preset threshold, the playing shutdown prompt is controlled to prompt the user that the display device 200 is shutdown. And if the playing progress is greater than or equal to a preset threshold value, controlling the display equipment to be automatically turned off.

In some embodiments, the display device 200 may also gather user information via the detector 230, such as gathering image information via a camera or receiving sound information with a microphone. The display device 200 may determine whether the user currently viewing the display device 200 is a child and whether several children are present through the user information acquired by the detector 230.

In some embodiments, when the first media asset attribute characterizes the first multimedia asset as a mixed program, the display device 200 obtains the user information collected by the detector 230, so that the display device determines whether a child exists in a user currently watching the multimedia asset according to the user information. When the user information determines that the child exists in the user currently watching the multimedia resource, the playing time length of the first multimedia resource is acquired to count the total playing time length of the child programs. When it is determined through the user information that there is no child among users currently viewing the multimedia asset, that is, the currently viewed program is an adult, the display apparatus 200 may not acquire the play duration of the first multimedia asset.

In some embodiments, the display device 200 may also determine from the user information that there are several children in the user currently viewing the multimedia asset. When there is a single child in the users currently watching the multimedia resources, that is, only one child is currently watching the program, the display device 200 adds the playing duration of the first multimedia resource to the total playing duration of the juvenile program watched by the child, so as to obtain the cumulative playing duration of the juvenile program by the child. When a plurality of children exist in the users currently watching the multimedia resources, the playing time length of the first multimedia resources is respectively added to the total playing time length of the juvenile programs watched by each child, and the accumulated playing time length of each child on the juvenile programs is respectively obtained. For example, there are a child and a child currently watching the program, and the display apparatus 200 accumulates the play time length to the accumulated play time lengths of the a child and the B child after acquiring the play time length of the first multimedia asset.

In some embodiments, the display device 200 may count the cumulative playing time length of each child, and control to stop watching the first multimedia asset when only one child has the cumulative playing time length of the child program to reach the corresponding watching time length among the plurality of children currently watching the multimedia asset.

For example, according to the user portraits, it is counted that there is one child a aged 2 and one child B aged 7 in a certain household, and the display device 200 sets the viewing time period of the child a to 1 hour and the viewing time period of the child B to 2 hours, respectively. If the A children and the B children are watching the XX cartoon at the same time and the accumulated playing time length of the B children is up to 45 minutes after the current A children are stopped, the accumulated playing time length of the B children is 1 hour and 5 minutes. After the display device 200 obtains that the playing time length of the XX cartoon reaches 15 minutes, the cumulative playing time length of the child a is calculated to reach 1 hour, and the recommended watching time length is reached, and the display device 200 can control the display device 200 to stop playing the XX cartoon.

The display equipment provided by the application can give off prompts in advance when the time for watching the program by the children is long, so that the influence of sudden shutdown on physical and mental health of the children is avoided, and the user experience is improved. In addition, when the program watching duration of children is required to be controlled, parents are not required to set the child mode, the operation flow of parents is reduced, and when the programs of children are switched to the programs of non-children, the display equipment is not shut down due to the overlong playing duration of the current program.

Based on the same inventive concept as the display device, the embodiment of the application further provides a method for controlling the viewing time length, which comprises the following steps: the display device 200 sets a viewing time period according to a user portrait in response to an input power-on operation, wherein children in different age stages counted according to the user portrait correspond to different viewing time periods. The display device 200 detects a first media asset attribute of a first multimedia asset corresponding to a media asset control in response to an input selection operation of the media asset control. When the first media asset attribute characterizes the first multimedia asset as a non-juvenile program, the display device 200 does not acquire the playing duration of the first multimedia asset. When the first media asset attribute characterizes that the first multimedia asset is a juvenile program, the display device 200 obtains a playing duration of the first multimedia asset, so that a total playing duration of the juvenile program is counted according to the playing duration of the first multimedia asset, and an accumulated playing duration is obtained. When the accumulated playing time length reaches the viewing time length, the display device 200 controls to stop viewing the first multimedia asset.
