When the user plays the video by using the display device 200, if the video source itself contains the corresponding subtitle information, the display device 200 displays the subtitle content while playing the video, so as to realize the correspondence between the sound and the subtitle, and the user can intuitively experience the content of the video from both the auditory sense and the visual sense.

However, in the actual situation of video playing, some problems of mismatching of subtitles and sound usually occur. This kind of problem is mostly caused by improper production when producing the film source caption; or due to problems of the display device 200 player itself. When this occurs, the sound and subtitles played on the display device 200 do not correspond, and the viewing experience of the user is easily affected.

Based on the above, the embodiment of the present application provides a subtitle adjusting method and a display device 200, which can provide a display page with an adjustable subtitle for a user, and adjust the occurrence time of the subtitle according to an operation instruction of the user, so as to solve the problem that sound does not correspond to the subtitle.

As described in the foregoing embodiments, the display device 200 in the embodiment of the present application may include the display 260 and the controller 250. The user can use the display device 200 to normally play the video resource he wants to see, and usually if the video resource has a subtitle file, the controller 250 parses the subtitle file and synchronously displays the obtained subtitle content on the display 260 so that the subtitle content matches the video sound content.

FIG. 5 illustrates a schematic diagram of an interaction between a controller 250 and a user, according to some embodiments.

When the subtitle content on the display 260 does not match the video sound, for example, the playing content of the video sound is faster than the subtitle display content or the playing content of the video sound is slower than the subtitle display content, the user may adjust the timing of displaying the subtitle on the display 260, so that the subtitle content matches the video sound.

In a specific manner, as shown in fig. 5, the user may input a page display instruction to the display device 200, so that the controller 250 controls the display 260 to display the subtitle adjustment page in response to the page display instruction. After the user watches the subtitle adjustment page, the user selects the time offset to be adjusted, and further inputs a subtitle adjustment instruction to the display device 200, and in response to the instruction, the controller 250 needs to calculate at what time point the currently played subtitle content should be displayed after adjustment, that is, the time offset selected by the user is added to the current playing progress time point of the video resource, and the obtained target playing progress time point is the time point at which the adjusted subtitle should be displayed. Finally, the controller 250 controls the display 260 to play the target subtitle content corresponding to the target play progress time point while playing the video resource corresponding to the target play progress time point. The adjusted target subtitle content and the video resource are played synchronously, and then the matching of the subtitle and the sound can be realized.

In addition, the user may input the instruction to the display apparatus 200 by operating a key of the remote controller, or may input the instruction to the display apparatus 200 equipped with the voice module by voice.

FIG. 6 illustrates a schematic diagram of a subtitling page, according to some embodiments.

As shown in fig. 6, on the subtitle adjustment page, several time offset options for adjusting the subtitle display time have been provided to the user through a previous setting. Wherein the different time offsets represent the time at which the user can adjust the display of the subtitle in advance (fast forward) or in delay (backward) at a time, e.g. 0.5s means that the user can display the subtitle in advance for 0.5s, -0.5s means that the user can display the subtitle in delay for 0.5 s.

FIG. 7 illustrates a schematic diagram of a menu page according to some embodiments. Fig. 8 illustrates a schematic diagram of a subtitle setting page according to some embodiments.

In some embodiments, the display device 200 may also provide a plurality of play functions or services for the current video asset when displaying the video asset, and these functions or services may be displayed on a general menu page, which may include options regarding subtitle settings, as shown in fig. 7. Moreover, the subtitle setting is not limited to the function of adjusting the subtitle playing time, and there may be some other functions of subtitle language setting or subtitle selection, which are also displayed on a general subtitle setting page, as shown in fig. 8. When the user selects the play adjustment option on the subtitle setting page, the display 260 displays the final subtitle adjustment page.

It can be seen that in some embodiments, the user needs to select different pages step by step to view the caption adjustment page. In this case, each operation of selecting a function option by the user may be regarded as inputting a control instruction, for example, a menu display instruction, a setting page display instruction, a page display instruction, or the like, to the display apparatus 200. Then, the controller 250 of the display apparatus 200 controls the display 260 to display a menu page in response to a menu display instruction input by the user; and in response to a set page display instruction, controlling a display to display a subtitle set page; and then controls the display 260 to display a caption adjustment page in response to the page display instruction.

In some embodiments, the setting of the time offset may be set differently according to service requirements, user requirements, etc. of the display device 200, and the time offset needs to be divided into positive and negative, where a positive time offset is used to indicate a duration of fast forward when the subtitle content is played, and a negative time offset is used to indicate a duration of rewind when the subtitle content is played. In some embodiments, it is desirable to set a number of equally spaced increasing positive time offsets in sequence from zero time offset to its positive direction and a number of equally spaced decreasing negative time offsets in sequence from zero time offset to its negative direction, e.g., 0.5s apart, then the number of time offsets set may be 2.5s, 2.0s, 1.5s, 1.0s, 0.5s, 0.0s, -0.5s, -1.0s, -1.5s, -2.0s, -2.5s, etc.

FIG. 9 illustrates a control flow diagram for controller 250 according to some embodiments.

As described in the foregoing embodiment, the premise that the user can adjust the subtitle is: the played video resources carry subtitle files. In order to accurately match the caption content with the content of the sound in the video, in some embodiments, as shown in fig. 9, the controller 250 may also parse the caption file in the video resource to obtain all the caption content in the video resource and the caption time period displayed by each caption content. And storing the caption content and the caption time period in a content array and a time array, respectively.

For example, the original subtitle file may be in the form of:

00:00:00,000-->00:05:00,000

That girl thinks that she's so fine；

(which may be indicated as "That girl thronks That she's so fine" is shown on the display 260 within the first 5.0s of the video);

00:06:00,000-->00:08:00,000

That soon she'll have my mind；

(which may be expressed as displaying a "That song shot'll have my mind" on the display 260 within 6.0s-8.0s of the video);

00:09:00,000-->00:11:00,000

That girl thinks that she's so smart；

(which may be expressed as "That girl thinks That she's so smart" displayed on the display 260 within 9.0s-11.0s of the video);

00:13:00,000-->00:15:00,000

That soon she'll have my heart；

(which may be expressed as displaying a "That song shot'll have my heart" on the display 260 within 13.0s-15.0s of the video);

after the parsing and grouping by the controller 250, the caption contents are respectively stored in the content array a [00:00:00,000- >00:05:00,000, 00:06:00,000- >00:08:00,000, 00:09:00,000- >00:11:00,000, 00:12:00,000- >00:15:00,000 ].

After the content array and the time array are stored, the controller 250 responds to a control instruction of a user, and obtains the target subtitle content corresponding to the target playing progress time point from the content array according to the corresponding relation between the time period and the subtitle content. The specific method can be that whether the target playing progress time point exists in any subtitle time period of the time array is detected; and taking the subtitle time period containing the target playing progress time point as a target time period under the condition that the target playing progress time point exists in any one subtitle time period; since the caption time periods correspond to the caption contents in the content array one to one, the controller 250 may also obtain the target caption content corresponding to the target time period from the content array.

For example, if the offset selected by the user is 2.5s, and the current playing progress time point of the video resource is 4.0s, then the calculated target playing progress time point is 6.5s, and the controller 250 detects That 6.5s exists in 00:06:00,000- >00:08:00,000 in the time array B, where 00:06:00,000- >00:08:00,000 is a target time period, and the controller 250 acquires the target subtitle content "That son shell' live my mind" corresponding to the target time period from the content array. For another example, if the offset selected by the user is-1.0 s, the current play progress time point of the video resource is 4.0s, then the calculated target play progress time point is 3.0s, and the controller 250 detects That 3.0s exists in 00:00:00,000- - >00:05:00,000 in the time array B, where 00:00:00,000- - >00:05:00,000 is a target time period, and then the controller 250 acquires the target subtitle content "thin girl thin skin" s fine "corresponding to the target time period from the content array.

Finally, the controller 250 controls the display 260 to play the target subtitle content corresponding to the target time period while playing the video resource corresponding to the target play progress time point.

In addition, if the time offset selected by the user is too large, the target playing progress time point does not exist in any subtitle time period, which indicates that the adjustment range of the user is too large, and the adjusted subtitle display time point cannot be matched with any subtitle content, so that the controller 250 controls the display 260 to play the video resource corresponding to the target playing progress time point, and at the same time, no subtitle content is played.

In some embodiments, the present application may provide a subtitling page as shown in fig. 6 for a user, and show each time offset option in a list on the subtitling page, where 0.0s represents a default value. In other embodiments, the application may also provide a subtitle adjustment page capable of autonomously filling in a time offset for the user, after the controller 250 obtains the time offset filled by the user, the target playing progress time point is obtained through the calculation as described in the above embodiments, the corresponding target subtitle content is obtained according to the manner described in the above embodiments, and finally, the controller 250 controls the display 260 to play the target subtitle content corresponding to the target playing progress time point while playing the video resource corresponding to the target playing progress time point.

As can be seen from the above, the display device 200 provided in the embodiment of the present application may provide a subtitle adjustment function for a user, and when the user uses the display device 200 to watch a video resource with subtitles, if it is found that sound is not matched with subtitles, a page display instruction may be input to the display device 200, and then the controller 250 of the display device 200 controls the display 260 to display a subtitle adjustment page; after watching the subtitle adjustment page, the user may input a subtitle adjustment instruction for selecting a certain time offset to the display device 200, and the controller 250 adds the time offset selected by the user to the current play progress time point of the video resource in response to the subtitle adjustment instruction to obtain a target play progress time point; finally, the controller 250 controls the display 260 to play the target subtitle content corresponding to the target play progress time point while playing the video resource corresponding to the target play progress time point. Therefore, the embodiment of the application can provide a display page with adjustable subtitles for a user, and adjust the occurrence time of the subtitles according to the operation instruction of the user so as to solve the problem that the sound and the subtitles do not correspond to each other.

The subtitle adjusting method provided in this embodiment of the present application may be applied to the controller 250 or some components that may implement the control function, as shown in fig. 10, where the method may include the following steps:

in step S101, in response to a page display instruction input by the user, the display 260 is controlled to display a subtitle adjustment page.

The subtitle adjustment page provides a time offset option for adjusting subtitle display time for a user; as shown in fig. 6 in particular, the different time offsets represent the time at which the user can adjust the subtitle display in advance (fast forward) or in delay (rewind) at a time.

Step S102, responding to a caption adjusting instruction input after a user watches a caption adjusting page, adding the time offset selected by the user and the current playing progress time point of the video resource to obtain a target playing progress time point.

Still taking the contents of the foregoing embodiment as an example, if the offset selected by the user is 2.5s and the current play progress time point of the video asset is 4s, the calculated target play progress time point is 6.5 s.

Step S103, controlling the display 260 to play the target subtitle content corresponding to the target playing progress time point while playing the video resource corresponding to the target playing progress time point.

For example, in the content array, the target subtitle content corresponding to 6.5s is "That soon she'll have my mind". Finally, the controller 250 controls the display 260 to display "That sound shot'll have my mind" at 6.5s of the video playing progress.

In some embodiments, the step of controlling the display 260 to display the subtitle adjustment page in response to the page display instruction input by the user may include:

in step S201, while controlling the display 260 to play the video resource and the subtitle content in the video resource, the display 260 is controlled to display a menu page in response to a menu display instruction input by a user.

The menu page may specifically include options such as subtitle setting, as shown in fig. 7.

In step S202, in response to a setting page display instruction for selecting a subtitle setting option input after the user views the menu page, the display 260 is controlled to display a subtitle setting page.

The subtitle setting page may specifically include options such as play adjustment, as shown in fig. 8.

In step S203, in response to a page display instruction for selecting a play adjustment option input after the user views the subtitle setting page, the display 260 is controlled to display a subtitle adjustment page.

In some embodiments, the present application may provide a caption adjustment page as shown in fig. 6 for the user, and show each time offset option in a list form on the caption adjustment page, where 0.0s represents a default value. In other embodiments, the application may also provide a subtitling page for the user that may autonomously fill in the time offset.

In some embodiments, the subtitle adjusting method may further include:

step S301, analyzing the caption file in the video resource, and obtaining all the caption contents in the video resource and the caption time periods displayed by each caption content.
